No unit test can prove somebody actually + * bumped the property (a test sees only the current state, never the delta), so this is a speed bump, not a + * gate: it makes the change visible in review, in the same commit, with the reason spelled out in the + * failure message. + * + *

Regenerating. Run this test, copy the "actual" block out of the failure message into + * {@code src/test/resources/authentication-plugin-surface.txt}, and bump the major of {@code authentication.plugin.api.version} in + * {@code fe/fe-authentication/pom.xml} in the SAME commit. + * + *

{@code Plugin} / {@code PluginFactory} / {@code PluginContext} from fe-extension-spi are frozen here + * too, and identically in the other three families' baselines. They are loaded parent-first for every family + * (see {@code ChildFirstClassLoader.DEFAULT_PARENT_FIRST_PACKAGES}), so a change to them breaks all four + * plugin kinds at once — and turns all four baselines red at once, each asking for its own bump. + * + *

Signatures are recorded with their return type, unlike the older + * {@code connector-metadata-methods.txt} baseline: a changed return type is a MAJOR change by the same + * definition, and a name-and-parameters-only record cannot see it. + */ +public class AuthenticationPluginSurfaceTest { + + private static final String BASELINE_RESOURCE = "/authentication-plugin-surface.txt"; + + /** The types a authentication plugin implements or calls.

The whole domain is optional — every default fails loud with a "not supported" message, which is + * the correct answer for a connector whose format cannot evolve columns.

+ * + *

Minimum implementation set:

+ *
    + *
  • Flat column evolution: implement the six top-level ops as a GROUP — + * {@link #addColumn}, {@link #addColumns}, {@link #dropColumn}, {@link #renameColumn}, + * {@link #modifyColumn}, {@link #reorderColumns}. Both connectors that support column evolution + * implement all six; a partial set means some {@code ALTER} statements succeed on a table while others + * report "not supported" on the same table.
    • + *
  • Nested column evolution: the four {@code *NestedColumn} ops plus + * {@link #modifyColumnComment}, only for a format that can evolve fields inside a struct.
    • + *
+ * + *

A heterogeneous gateway connector must route BOTH groups to its sibling. Routing only the flat six is a + * silent trap: nested {@code ALTER} statements then hit the gateway's own throwing default even though the + * sibling supports them.

+ * + *

Dotted column paths (e.g. {@code s.b}, {@code arr.element.c}, {@code m.value}) are carried neutrally by + * {@link ConnectorColumnPath}; a single-part path targets a top-level column. The fe-core bridge routes + * top-level ADD/DROP/RENAME/MODIFY through the flat ops and reserves the {@code *NestedColumn} ops for the + * nested case, except {@link #modifyColumnComment}, which is the sole entrypoint for + * {@code MODIFY COLUMN ... COMMENT} (flat and nested alike).

  • No optional per-child list (nullability, comment, field id, comment-specified) may be + * longer than {@link #getChildren()}. Shorter stays legal — those four are read + * index-tolerantly, so a missing entry means "not carried" and falls back to its default.
    • + *
  • The type name is matched case-insensitively, so {@code "Struct"} cannot dodge the check. Any + * other type name is left alone: {@code typeName} is a free-form string with no vocabulary, so + * "this is not a complex type" cannot be inferred from it.

Read this page before adding a connector or extending these interfaces. It records the rules the + * existing connectors follow, and — where a rule is not yet fully honored — says so explicitly instead of + * describing the target state as if it were already true. Every rule below can be checked against the code + * that is cited with it; when the two disagree, the code wins and this page is the bug.

+ * + *

Rule 1 — declare a capability in exactly one of three layers

+ * + *
    + *
  1. A whole subsystem is present or absent → a getter on {@link Connector} that returns + * {@code null} when the subsystem is absent: {@code getScanPlanProvider()}, + * {@code getWritePlanProvider()}, {@code getProcedureOps()}, {@code getEventSource()}, + * {@code getRestPassthrough()}. These stay {@code null}-returning rather than {@code Optional}: the + * engine already branches on {@code null}, and changing the shape would be pure churn.
    2. + *
  2. A switch inside one subsystem → a {@code supportsXxx()} / {@code requiresXxx()} method on + * THAT subsystem's provider, which is the single and ONLY source of truth. {@link Connector} used to + * carry null-safe mirrors of the write switches so the engine never had to null-check; they were deleted, + * because a mirror is a second overridable answer to one question and a connector overriding one while + * leaving the provider at its default would produce two divergent answers with no compile error. The + * engine fetches the provider and asks it, treating a {@code null} provider as "not supported".
    3. + *
  3. A gate the engine must evaluate during static planning, before any provider is reachable → + * a constant in {@link ConnectorCapability}, resolved additively as + * (connector-level set) ∪ (per-table set). A switch that corresponds one-to-one with a provider does + * NOT belong here. Worked example, already written into the code: {@code SUPPORTS_SORT_ORDER} is an + * enum constant because the engine must decide during analysis whether {@code CREATE TABLE ... ORDER BY} + * is accepted, and no write-plan provider exists at that point; the runtime row-ordering sink trait + * {@code ConnectorWritePlanProvider.requiresFullSchemaWriteOrder()} lives on the provider. Both mention + * "write", but one gates a DDL clause and the other shapes the write path.
    4. + *
+ * + *

Use {@code Optional} for a missing value and {@code null} only for an absent + * subsystem; they are not two competing idioms for the same thing.

+ * + *

Current deviations. (a) A new switch must default to {@code false} (opt-in), so that adding a + * capability can never change an existing connector's behavior. One legacy switch violates this and defaults + * to {@code true}: {@code ConnectorPushdownOps.supportsCastPredicatePushdown(ConnectorSession)} — see the + * risk paragraph in its own javadoc, and do not copy its polarity. (b) The {@code supportsXxx()} shape also + * appears on non-provider interfaces ({@code ConnectorPushdownOps}, {@code ConnectorSchemaOps}, + * {@code ConnectorTableOps}); those are per-operation switches on the interface that owns the operation, + * which is consistent with layer 2, but there is no provider object to attach them to. (c) Per-table + * refinement of {@link ConnectorCapability} is honored for only five of the thirteen constants today, and + * each constant's own javadoc states its scope (catalog-only, or catalog ∪ per-table) and why; do not + * assume a newly added constant can be refined per table.

+ * + *

Rule 2 — which exception to throw, and when to fail loud

+ * + *

Two engine paths translate connector exceptions into user-facing errors, and they accept different + * types. Getting this wrong does not break anything visibly; it only degrades the error the user sees into an + * internal FE exception.

+ * + *
    + *
  • Metadata, DDL, DML and scan-planning paths → throw {@link DorisConnectorException} (or a + * subclass). It is the family the engine catches and re-wraps (for example into {@code DdlException}) on + * those paths.
    • + *
  • Catalog property validation ({@code ConnectorProvider.validateProperties}) → throw + * {@code IllegalArgumentException}. It is the ONLY type the engine unwraps there + * ({@code PluginDrivenExternalCatalog.checkProperties} catches it and re-throws its message as + * {@code DdlException}); several connectors depend on this and say so at their throw sites. Do not + * "correct" these to {@link DorisConnectorException}.
    • + *
+ * + *

Everything else ({@code UnsupportedOperationException}, {@code IllegalStateException}, plain + * {@code RuntimeException}) is untranslated and surfaces as an internal error. The one accepted use of + * {@code UnsupportedOperationException} is the "this optional SPI method is not implemented" idiom.

+ * + *

Subclass {@link DorisConnectorException} when the CALLER must distinguish outcomes, not to build + * a taxonomy for its own sake. Shipped precedent: {@code HiveDirectoryListingException} exists so the scan + * path can catch only a skippable listing failure while a plain {@link DorisConnectorException} + * still fails the query loud.

+ * + *

Fail loud vs. degrade silently. Anything the user explicitly asked for — DDL, writes, an explicit + * {@code ANALYZE ... WITH SAMPLE} — must fail loud, because a swallowed error there produces a wrong result + * or a wrong statistic that then looks authoritative. Anything the engine attempts opportunistically for + * optimization must degrade silently (return empty / a default, and log), because it must never be able to + * fail a query that would otherwise succeed.

+ * + *

Rule 3 — thrift types only at the BE protocol boundary

+ * + *

BE is C++ and has no plugin mechanism, so a payload destined for BE has to be a thrift type. That is the + * only reason thrift appears in this module, and the complete list of places it does is:

+ * + *
    + *
  • {@code api/scan/ConnectorScanPlanProvider} — {@code TFileCompressType}, {@code TFileScanRangeParams}, + * {@code TTableFormatFileDesc}
    • + *
  • {@code api/scan/ConnectorScanRange} — {@code TFileRangeDesc}, {@code TTableFormatFileDesc}
    • + *
  • {@code api/handle/ConnectorWriteHandle} — {@code TSortInfo}
    • + *
  • {@code api/write/ConnectorSinkPlan} — {@code TDataSink}
    • + *
  • {@link ConnectorTableMetadataOps#buildTableDescriptor} — {@code TTableDescriptor} (written as an inline + * fully-qualified name, not an import)
    • + *
+ * + *

Do not add a method that takes a thrift type as a PARAMETER. A new return value that must carry a BE + * payload may only reuse a type already on that list. {@code fe-thrift} is a {@code provided} dependency + * here: it is supplied by the parent classloader at runtime and is not part of a plugin package.

+ * + *

Current deviation. {@code fe-connector-spi} deliberately avoids thrift even for BE-bound data + * (it passes an enum NAME as a {@code String}, a neutral broker-address type, and a thrift enum's integer + * VALUE as an {@code int}). That is a local convention in that module, not a module-level invariant: it + * depends on this module, which depends on {@code fe-thrift}. Whether to unify the two styles is out of + * scope here.

+ * + *

Rule 4 — what belongs in this module and what belongs in {@code fe-connector-spi}

+ * + *

The split is by WHO IMPLEMENTS the type. A type the connector implements and the engine consumes + * belongs here ({@code fe-connector-api}). A type the engine implements and the connector consumes, + * plus the service-discovery entry point, belongs in {@code fe-connector-spi}. The dependency runs one way, + * {@code spi} → {@code api}; nothing here may reference the {@code spi} package.

+ * + *

The two module names are inverted relative to common usage (elsewhere, including Trino, + * "SPI" names what the plugin implements and "API" names the engine services it consumes). Here + * {@code fe-connector-api} holds the types a connector implements and {@code fe-connector-spi} holds the + * handful it consumes. The names are deliberately NOT being changed — renaming would touch every connector + * pom and the engine's dependencies for a naming win only — so read the content, not the name.

+ * + *

Current deviation. {@link ConnectorSession}, {@code ConnectorHttpSecurityHook} and + * {@code ConnectorValidationContext} are engine-implemented yet live here. This is a known misplacement, + * left alone because moving them would rewrite imports in every connector.

+ * + *

Rule 5 — lifecycle, and which methods run off the query thread

+ * + *
    + *
  • {@link Connector} — one instance per catalog, created once (see its own class javadoc).
    • + *
  • {@link ConnectorMetadata} — exactly one instance per catalog per statement, closed + * deterministically when the statement ends. The engine's single entry point for obtaining one + * ({@code PluginDrivenMetadata}) states this contract; {@link Connector#getMetadata} is not called + * anywhere else in the engine. {@link ConnectorMetadata#close()} must be idempotent, and one instance + * must not be shared across threads.
    • + *
  • {@link ConnectorStatisticsOps} — may run on engine background pools, and the engine pins no + * thread context classloader on any of them. See that interface's class javadoc for the pools and for + * what a connector has to do about it. This is the one contract on this page that causes a crash rather + * than a wrong answer when it is ignored.
    • + *
+ * + *

Rule 6 — a javadoc statement about ENGINE behavior must cite the engine code

+ * + *

These interfaces are the only behavioral contract a connector author has: connectors are packaged and + * class-loaded separately and cannot read the engine. A javadoc line that describes what the engine does with + * a value, and is wrong, is worse than no line at all — it produces an implementation that compiles, runs, + * and silently returns wrong results. So when documenting engine behavior, name the engine class (and + * ideally the method) that does it, so the next reader can re-verify instead of trusting the sentence.

+ * + *

Rule 7 — where a connector's tunable knobs live

+ * + *

Pick the channel by the SCOPE of the value. Only the second one obliges anyone to touch the engine, so + * a knob that can be catalog-scoped should be.

+ * + *
    + *
  • Per catalog → a key in {@code CREATE CATALOG ... PROPERTIES(...)}. The engine hands the + * whole property map to {@code ConnectorProvider.create} and exposes the same map per query through + * {@link ConnectorSession#getCatalogProperties()}; reject a bad value in + * {@code ConnectorProvider.validateProperties} (see Rule 2 for the exception type). Key names, parsing + * and defaults stay entirely inside the connector — prefix the key with the connector's type name + * so two connectors cannot collide. Shipped precedent: {@code hive.ignore_absent_partitions}, + * {@code hive.enable_hms_events_incremental_sync} and {@code hive.hms_events_batch_size_per_rpc} are + * declared in {@code HiveConnectorProperties} and read in {@code HiveScanPlanProvider} / + * {@code HiveConnector}; those key strings appear nowhere in {@code fe-core}.
    • + *
  • Per FE process (one deployment-level value for every catalog, e.g. a driver directory) + * → an {@code fe.conf} field forwarded through {@code ConnectorContext.getEnvironment()} by + * {@code DefaultConnectorContext.buildEnvironment}. This is the one knob shape that requires an engine + * change per key, so use it only when the value genuinely is not per catalog.
    • + *
  • Per session → read the query's session variables from + * {@link ConnectorSession#getSessionProperties()}. The connector does not declare them; it looks up the + * names it cares about.
    • + *
+ * + *

There is deliberately no declarative property-descriptor mechanism here. One was carried over + * from Trino ({@code ConnectorPropertyMetadata} plus two {@link Connector} getters) and shipped for several + * releases with zero implementors and zero consumers; it was removed rather than wired up, because in Doris + * it would not have solved the thing it looks like it solves — there is no {@code SET SESSION + * catalog.property} syntax to feed, and per-catalog values already arrive through the map above. If you find + * yourself wanting the engine to validate unknown catalog property keys, that belongs in + * {@code ConnectorProvider.validateProperties}, which already exists and already runs.

This is the ONLY vocabulary a connector receives for filter pushdown. A connector translates it into its + * own dialect (an iceberg {@code Expression}, a paimon {@code Predicate}, an ES query DSL document, a SQL + * {@code WHERE} fragment). Getting a translation subtly wrong does not fail the query — it silently returns + * the wrong number of rows, and {@code EXPLAIN} shows nothing unusual. So read Rule 1 before writing a + * converter; the three shipped row-loss bugs fixed in this area were all the same mistake.

+ * + *

Rules 1–3 are the contract. Rules 4–6 record what the engine actually produces and what it actually does + * with your answer, each citing the engine class so it can be re-verified (see Rule 6 of + * {@code org.apache.doris.connector.api} — the engine is not on a connector's classpath, so an unverifiable + * sentence here is worse than no sentence).

+ * + *

Rule 1 — translate exactly, or drop the whole conjunct. Never narrow it

+ * + * 
+ *   can express it exactly    -> push it down
+ *   cannot express it exactly -> drop the WHOLE conjunct and let BE evaluate it
+ *   never                     -> push a "close enough" predicate that matches FEWER rows
+ *
+ * + *

A pushed predicate that is too WIDE is recoverable: the engine keeps the conjuncts and BE re-evaluates + * them, so the extra rows are filtered out before the user sees them. A pushed predicate that is too NARROW + * is not recoverable by anything: the connector has already skipped files, partitions or row groups, and the + * rows never reach BE. That asymmetry — not convenience — is why dropping is always allowed and narrowing + * never is.

+ * + *

The precondition on "wide is safe". It holds only while the engine still has the conjuncts. If + * you tell the engine you consumed them (a {@code null} remaining filter, or index-level tracking — Rule 5), + * then a predicate that is too wide starts returning EXTRA rows. Read Rule 5 before claiming full pushdown.

+ * + *

Two concrete instances of the mistake, both shipped and both fixed:

+ *
    + *
  • {@code c <=> 5} translated to {@code c IS NULL}. Null-safe equality against a NON-NULL literal is plain + * equality; only against a NULL literal is it {@code IS NULL}. Collapsing the two cases returned zero + * rows for a table whose only match was {@code c = 5}. See {@link ConnectorComparison}.
    • + *
  • {@code s LIKE 'a_c%'} translated to "starts with {@code a_c}". {@code _} is a single-character + * wildcard, so {@code 'abc'} matches the user's pattern but not the prefix. See {@link ConnectorLike}.
    • + *
+ * + *

Rule 2 — which direction is safe depends on what the predicate is FOR

+ * + *

The same expression tree is used for three purposes, and "drop it" is only safe in two of them:

+ * + * + * + * + * + * + * + * + * + * + * + * + * + *
Safe direction per use
UseDropping a conjunct meansCorrect behavior
Scan pushdown ({@link org.apache.doris.connector.api.ConnectorPushdownOps#applyFilter}, + * {@code ConnectorScanPlanProvider.planScan})the filter widens; BE re-evaluates and covers itdropping allowed, narrowing forbidden
Write-time conflict detection + * ({@link org.apache.doris.connector.api.handle.ConnectorTransaction#applyWriteConstraint})conflict detection widens, i.e. gets more conservativedropping allowed
{@code ALTER TABLE ... EXECUTE ... WHERE} rewrite scopingMORE files get rewritten — dropping the whole WHERE rewrites the entire tablemust throw; dropping is not allowed
+ * + *

The engine already enforces the third row on its side: {@code UnboundExpressionToConnectorPredicateConverter} + * is strictly all-or-nothing and throws when any part of the {@code WHERE} cannot be represented neutrally. + * A connector consuming such a predicate must hold the symmetric invariant — a conjunct it cannot turn into + * file pruning is a hard error there, not a silent drop.

+ * + *

Rule 3 — column names, and what is NOT specified here

+ * + *

{@link ConnectorColumnRef#getColumnName()} carries the name as the engine knows it. Case handling is + * currently decided per connector and is deliberately not specified: paimon lower-cases both sides + * before matching field names, jdbc maps through its own remote-name table. If your remote system is + * case-sensitive, decide explicitly rather than assuming the engine normalized anything.

+ * + *

Rule 4 — what the engine actually produces

+ * + *

One producer. Every tree is built by {@code ExprToConnectorExpressionConverter} (fe-core). The + * other two entry points — {@code NereidsToConnectorExpressionConverter} for DELETE/UPDATE/MERGE and + * {@code UnboundExpressionToConnectorPredicateConverter} for {@code EXECUTE ... WHERE} — route literals and + * types back through it, so literal encoding is identical on all three paths.

+ * + *

Shape of the root. {@code convertConjuncts} returns the single node directly when there is + * exactly one conjunct (the root is NOT a {@link ConnectorAnd}), and a boolean {@code true} + * {@link ConnectorLiteral} when there are none. Do not assume an {@code AND} root.

+ * + *

Two arrival paths, only one of which strips CAST.

+ *
    + *
  • {@link ConnectorFilterConstraint} handed to + * {@link org.apache.doris.connector.api.ConnectorPushdownOps#applyFilter} is built by + * {@code PluginDrivenScanNode.buildFilterConstraint} and is NOT filtered: + * {@code supportsCastPredicatePushdown} is not consulted, so predicates wrapping a CAST reach you as-is + * (the converter unwraps the {@code CastExpr} node itself, handing you the inner expression).
    • + *
  • The {@code Optional filter} handed to {@code ConnectorScanPlanProvider.planScan} + * and {@code getScanNodePropertiesResult} comes from {@code PluginDrivenScanNode.buildRemainingFilter}, + * which DOES drop conjuncts containing a CAST when + * {@link org.apache.doris.connector.api.ConnectorPushdownOps#supportsCastPredicatePushdown} is false.
    • + *
+ * + *

Literal value domain. {@link ConnectorLiteral#getValue()} is one of exactly eight Java shapes. + * Note that {@code Integer} is never produced and that {@code LARGEINT} arrives as a decimal + * {@code String}:

+ * + * + * + * + * + * + * + * + * + * + * + * + * + *
Doris literal type to Java value
Doris typeJava class
NULL literal (any type){@code null} — see {@link ConnectorLiteral#isNull()}
BOOLEAN{@code Boolean}
TINYINT / SMALLINT / INT / BIGINT{@code Long} (never {@code Integer})
FLOAT / DOUBLE{@code Double}
DECIMAL*{@code BigDecimal}
CHAR / VARCHAR / STRING{@code String}
DATE / DATEV2{@code LocalDate}
DATETIME / DATETIMEV2{@code LocalDateTime}
anything else, incl. LARGEINT, IPV4/IPV6, JSON{@code String} from {@code Expr.getStringValue()}
+ * + *

Rule 5 — telling the engine what you consumed: two protocols, one of which does nothing

+ * + * + * + * + * + * + * + * + * + * + *
Residual protocols and their real effect
What you returnWhat the engine does
{@link FilterApplicationResult#getRemainingFilter()} == {@code null}{@code PluginDrivenScanNode.convertPredicate} clears ALL conjuncts. BE re-evaluates nothing, so + * every predicate you were given must have been pushed EXACTLY.
{@code getRemainingFilter()} != {@code null} (any expression, including the original one)Nothing is removed. The engine keeps every conjunct; matching residual sub-expressions back + * to individual conjuncts is not implemented. Returning "the half I did not push" does not give you + * credit for the half you did.
{@code ScanNodePropertiesResult} with not-pushed conjunct indices{@code PluginDrivenScanNode.pruneConjunctsFromNodeProperties} really does prune: conjuncts whose + * index you did NOT report are removed. This is the only protocol with per-conjunct granularity; + * it is used by exactly one shipped connector (es).
+ * + *

Consequence for everyone else: all three {@code applyFilter} implementations shipped today return the + * original expression as the residual, so their predicates are also evaluated on BE. That is correct but not + * free — and it is the reason a slightly-too-wide pushdown is survivable today.

+ * + *

Rule 6 — {@link ConnectorFunctionCall} is also the fallback carrier. Do not match it by name

+ * + *

{@code ExprToConnectorExpressionConverter.fallback} turns any expression it does not model into a + * {@link ConnectorFunctionCall} whose name is the rendered Doris SQL text and whose argument list is + * empty. It is not a function call at all. Matching function names blindly will make a connector + * translate {@code my_udf(a, b) = 1} as a call to a function literally named {@code "my_udf(a, b) = 1"}. + * jdbc handles this deliberately: an argument-less call whose name is not a plain identifier is emitted as a + * pre-rendered SQL fragment ({@code JdbcQueryBuilder}).

+ * + *

Two related shapes to expect:

+ *
    + *
  • {@code LIKE ... ESCAPE '!'} (the three-argument form) does not arrive as a + * {@link ConnectorLike} — the converter only builds one for the two-argument form, so it arrives as a + * {@code ConnectorFunctionCall} named {@code like} with three arguments. A connector that only handles + * {@link ConnectorLike} therefore never sees a custom escape character, and may assume the fixed + * backslash escape documented on {@link ConnectorLike}.
    • + *
  • Arithmetic and genuine scalar functions arrive as {@link ConnectorFunctionCall} with real arguments; + * those are safe to match by name.
    • + *
+ * + *

Anything you cannot interpret confidently falls under Rule 1: drop the conjunct.

It memoizes the + * (expensive) {@code FileSystem.listStatus} of each partition directory, keyed by {@code (db, table, location)}. + * + *

Why this exists. Legacy fe-core kept directory listings in the engine-side + * {@code HiveExternalMetaCache}'s {@code file} entry; once a hive catalog becomes plugin-driven that cache stops + * routing to it, so without this connector-owned cache every scan (and every periodic row-count refresh) would + * re-list every partition directory from the filesystem. Trino keeps the equivalent {@code CachingDirectoryLister} + * as a layer separate from its metastore cache — D2 mirrors that split.

+ * + *

Who reads it. {@link HiveScanPlanProvider} (the scan hot path) and + * {@link HiveConnectorMetadata#estimateDataSizeByListingFiles} (the row-count estimate) — both go through the SAME + * instance, held as a {@code final} field on the per-catalog {@link HiveConnector} (the only object that outlives a + * single query; the scan provider / metadata are rebuilt per call). A scan therefore warms the estimate and vice + * versa.

+ * + *

TCCL. The entry is contextual-only + manual-miss + no auto-refresh, so the loader runs synchronously on + * the CALLING thread — which is already pinned to the plugin classloader (the scan thread by + * {@code PluginDrivenScanNode.onPluginClassLoader}; the stats thread by {@code estimateDataSizeByListingFiles} + * itself). A background refresh thread would NOT inherit that pin and Hadoop's {@code FileSystem} reflection would + * fail to resolve its impl.

+ * + *

Failures are not cached, and are split by blast radius. The loader never caches a failed load (matching + * {@code MetaCacheEntry}'s null-is-a-miss / exception-propagates contract). A SYSTEMIC filesystem-resolution failure + * ({@link FileSystem#forLocation} unresolvable scheme/storage, or a lazily-surfaced {@code "No FileSystem for + * scheme"} — it fails for every partition of the table) is thrown as a plain {@link DorisConnectorException} and the + * scan path lets it propagate to fail the query loud. A LOCAL per-directory failure ({@link FileSystem#list}: this + * partition missing/unreadable) is thrown as {@link HiveDirectoryListingException} and the scan path skips just that + * partition with a warning (the pre-cache tolerance). The estimate path degrades to {@code -1} on either. This keeps + * a broken storage config from silently returning an empty scan (legacy failed {@code FileSystem.get} loud) while + * preserving one-bad-partition resilience.

WHY these assertions matter:

+ *
    + *
  • Names-only, no per-partition round-trip. The single most important invariant: listing + * partitions must call {@code get_partition_names} ONLY and never {@code get_partitions_by_names}. + * Legacy's hot partition-pruning path ({@code HiveExternalMetaCache.loadPartitionValues}) listed names + * only; paying the heavier per-partition fetch here would regress every partitioned-hive query. The + * fake fails loud if {@code getPartitions} is touched.
    • + *
  • {@code lastModifiedMillis} and the stat fields are UNKNOWN(-1). This is the deliberate + * §4.2 decision (freshness deferred to the MVCC/MTMV step); a regression that silently started filling + * them would re-introduce the round-trip this method exists to avoid.
    • + *
  • Value maps are keyed by remote partition-column name and unescaped. + * {@code PluginDrivenExternalTable.getNameToPartitionItems} reads values back by remote name, and + * legacy decoded Hive path-escaping ({@code %2F} -> {@code /}); getting either wrong corrupts the + * partition-value view.
    • + *
  • Unpartitioned tables list nothing without any metastore call (parity guard).
    • + *
  • The filter is ignored (legacy materialized the full set and pruned FE-side).

WHY (Rule 9): these diverts are what makes a foreign iceberg/hudi handle START flowing out of getTableHandle, + * which activates every {@code instanceof HiveTableHandle} guard-and-forward override in {@link HiveConnectorMetadata} + * (routed 3-way by the owning sibling).

    + *
  • An iceberg-on-HMS table must return the iceberg connector's handle unchanged, and a hudi-on-HMS table the + * hudi connector's handle unchanged — so each sibling's own unconditional concrete-handle cast on its + * scan/metadata path succeeds — NOT a HiveTableHandle stamped ICEBERG/HUDI, which would CCE the moment the + * sibling cast it.
    • + *
  • Routing must be BY TYPE and to the RIGHT sibling: a HUDI table must reach the hudi sibling, never the iceberg + * one (diverting it to iceberg would CCE / silently mis-read hudi data).

  • The HUDI arm must not swallow the genuine-UNKNOWN fail-loud (an unsupported non-view format still throws).

WHY (Rule 9): the two overrides encode two correctness-critical decisions.

+ *
    + *
  • {@code supportsBatchScan}: batch iff PARTITIONED and NOT transactional. ACID tables are excluded so the + * per-batch resolution does not open (and leak) a metastore read transaction per batch — they keep the + * synchronous path.
    • + *
  • {@code planScanForPartitionBatch}: hive's {@code planScan} resolves partitions from the handle's pruned + * set and IGNORES the passed partition set, so hive MUST override the batch hook to scope resolution to the + * batch. If it inherited the SPI default (which re-runs the whole-pruned-set {@code planScan} per batch), + * every partition's files would be emitted once per batch — DUPLICATE ROWS. The {@code ranges.size()==1} + * (and single-location listing) assertion below fails precisely under that bug.
    • + *

Why this exists. Without this decorator the hive connector would cache nothing — {@code getTable}, + * {@code listPartitionNames} and {@code getPartitions} would be fresh Thrift RPCs on every scan. Legacy fe-core + * kept these in the engine-side {@code HiveExternalMetaCache}, which stops routing to a hive catalog once + * it becomes a plugin-driven ({@code SPI_READY}) catalog. This decorator re-homes that caching inside the + * connector (Trino {@code CachingHiveMetastore} shape), so the connector stays performance-neutral vs + * legacy after the cutover. Because the {@code HmsClient} is also held by the hudi/iceberg siblings from + * this same module, the decorator is reusable by them later.

+ * + *

What it caches (4 methods), each on its own {@link MetaCacheEntry} configured from catalog + * properties {@code meta.cache.hive..(enable|ttl-second|capacity)} (defaults mirror the legacy + * fe-core {@code Config} values — the connector is {@code Config}-free):

+ *
    + *
  • {@code getTable} — keyed by {@code (db, table)} → {@link HmsTableInfo}.
    • + *
  • {@code listPartitionNames} — keyed by {@code (db, table, maxParts)} → partition-name list. Real + * callers pass the unbounded {@code maxParts}, so this is effectively one entry per table; keeping + * {@code maxParts} in the key keeps a bounded request from ever being served a fuller list.
    • + *
  • {@code getPartitions} — one entry PER PARTITION, keyed by {@code (db, table, partition-values)} → + * {@link HmsPartitionInfo}. A bulk request looks up each requested name (parsed to its values) and + * fetches only the misses in a single delegate call, storing each returned partition under its OWN + * values — so overlapping requests SHARE partition entries and the capacity bounds partition OBJECTS + * (legacy {@code HiveExternalMetaCache} / Trino {@code CachingHiveMetastore} shape), not request-lists. + * {@link HmsPartitionInfo} carries {@code transient_lastDdlTime} in its parameters, which a later step + * reads through this cache for the table max-modify-time.
    • + *
  • {@code getTableColumnStatistics} — keyed by {@code (db, table, requested-column-list)} → the + * (possibly sparse or empty) stats list. Same RPC-argument granularity; the empty-list "no stats" + * result is a legitimate cached value (only {@code null} loads are skipped). This is the planner + * column-stats fast path, off the scan hot path, so it caches at low priority but on the same + * machinery as the rest.
    • + *
+ * + *

Pass-through. Every other read, plus every write / DDL / ACID method, is passed straight + * through to the delegate. A later invalidation step arms {@link #flush(String, String)} / + * {@link #flushDb(String)} / {@link #flushAll()} onto {@code REFRESH TABLE} / {@code REFRESH DATABASE} / + * {@code REFRESH CATALOG}. This decorator does NOT + * self-invalidate around writes — coarse REFRESH + TTL bound staleness.

+ * + *

Cache-value safety. {@code HmsTableInfo} / {@code HmsPartitionInfo} / {@code HmsColumnStatistics} + * are immutable (all fields final, collections unmodifiable), so caching them by reference is safe. The + * three list-returning methods cache and return the delegate's outer {@code List} container by reference and + * do NOT defensively copy it — its elements are immutable but the container is shared, so callers must treat + * a returned collection as read-only (the codebase-wide metadata-cache convention). Null loads are never + * cached (the framework treats {@code null} as a miss), and a loader exception ({@link HmsClientException}) + * propagates to the caller and is not cached.

+ * + *

Live since the hms flip. {@code HiveConnector.createClient} wraps the pooled + * {@code ThriftHmsClient} in this decorator (see {@code HiveConnector.wrapWithCache}), so every hmsClient read + * in {@code HiveConnectorMetadata} — including the freshness probes — is cache-backed. Fully unit-testable in + * isolation.

    Holds a single SDK {@link Transaction} / {@link Table} for one SQL statement and the accumulated + * commit fragments ({@link TIcebergCommitData}, fed back from BE via {@link #addCommitData}). The SDK + * transaction is opened — through the {@link IcebergCatalogOps} seam wrapped in the auth context — by + * {@link #beginWrite}; {@link #commit()} builds the SDK operation for the {@link WriteOperation} from the + * accumulated fragments, stages it onto the transaction, then flushes with {@code commitTransaction()}.

    + * + *

    Op selection (P6.3-T04). Unlike the legacy class (which split {@code finishInsert} from + * {@code commit}), the unified {@link ConnectorTransaction} SPI exposes only {@link #commit()} — so the + * manifest build happens there (mirroring maxcompute): INSERT → AppendFiles; OVERWRITE dynamic → + * ReplacePartitions; OVERWRITE empty/unpartitioned → OverwriteFiles (clears the table); OVERWRITE static + * → OverwriteFiles.overwriteByRowFilter; DELETE → RowDelta (deletes); UPDATE/MERGE → RowDelta + * (rows + deletes). The {@code IcebergWriterHelper} equivalents (DataFile / DeleteFile / Metrics / + * PartitionData) live in {@link IcebergWriterHelper}.

    + * + *

    Conflict detection (P6.3-T05). The DELETE/MERGE {@link RowDelta} commit is guarded by the + * optimistic conflict-detection validation suite (validateFromSnapshot from the begin-time + * {@link #baseSnapshotId} / conflictDetectionFilter / serializable validateNoConflictingDataFiles / + * validateDeletedFiles / validateNoConflictingDeleteFiles / validateDataFilesExist) and, on a V3 table, the + * deletion-vector "rewrite previous delete files" {@code removeDeletes}. The conflict-detection filter is the + * O5-2 write constraint ({@link #applyWriteConstraint}, a neutral {@link ConnectorPredicate} converted lazily + * at commit) ANDed with a commit-time identity-partition filter derived from the commit fragments.

    + * + *

    Live since the iceberg SPI cutover. An {@code iceberg} catalog is served by this connector + * plugin, so plugin-driven iceberg writes route through this class ({@link #beginWrite} is wired by + * {@code planWrite}). The txn-id is the engine-allocated Doris global id, so the generic + * {@code PluginDrivenTransactionManager} registers it in both the per-manager map and + * {@code GlobalExternalTransactionInfoMgr} — no per-connector registration code is needed, mirroring + * maxcompute.

    Cache invalidation is the engine's responsibility (H-6 fix): the dispatch must NOT invalidate any + * cache — after the procedure returns, the engine ({@code ConnectorExecuteAction}) refreshes the mutated table + * through the standard refresh-table path, the only path that drops both the engine meta cache (LOCAL-name + * keyed) and the connector's own per-table cache (REMOTE-name keyed). This used to be asserted here through a + * recording context; it is now guaranteed structurally, because the connector-to-engine invalidation SPI no + * longer exists — there is nothing for a dispatch to call.

    WHY this matters: BE has no {@code split_type} field on the wire — it classifies a + * MaxCompute split purely by the numeric {@code split_size} it receives. {@code MaxComputeJniScanner} + * does {@code if (splitSize == -1) BYTE_SIZE else ROW_OFFSET} (MaxComputeJniScanner.java:125-128), + * then in {@code open()} builds {@code IndexedInputSplit} (BYTE_SIZE) or + * {@code RowRangeInputSplit(sessionId, startOffset, splitSize)} (ROW_OFFSET). If a byte_size split + * carries a real byte count (e.g. 268435456) instead of {@code -1}, BE silently mis-reads it as a + * ROW_OFFSET split and returns CORRUPT data (no error). So the provider's byte_size branch MUST emit + * size {@code -1}; this mirrors legacy {@code MaxComputeScanNode}'s + * {@code MaxComputeSplit(..., length=-1, fileLength=splitByteSize, ...)}.

    + * + *

    This test drives the PROVIDER's real byte_size split-building code + * ({@code buildSplitsFromSession}) with offline fakes (no network, no live ODPS) — so it locks the + * provider's CHOICE of {@code -1}, not merely the range mechanism. Reverting the byte_size branch to + * {@code .length(splitByteSize)} makes {@code byteSizeBranchEmitsMinusOneSizeSentinel} FAIL + * (getSize() would become the real byte size). The row_offset case is the contrast that proves only + * byte_size uses the sentinel — its size is the real row count, never {@code -1}.

    + * + *

    The connector module has no fe-core / Mockito; we reach the private split-building method via + * reflection and stub the ODPS {@code TableBatchReadSession} / {@code InputSplitAssigner} with plain + * Serializable fakes ({@code serializeSession} writes the session, so it must be Serializable).

    In production the connector runs inside {@code ConnectorPluginManager}'s plugin isolation, + * where {@code org.apache.doris.connector.} / {@code org.apache.doris.filesystem.} are parent-first + * (the shared SPI) while the connector impl and its third-party deps — including the ODPS SDK + * ({@code com.aliyun.odps.*}) — load child-first, getting an isolated copy per plugin. Risk R-004 is + * that loading the ODPS SDK in such isolation breaks (NoClassDefFoundError / ClassCastException) or + * that a per-plugin SDK copy poisons a process-wide singleton.

    + * + *

    Note that the two module names are inverted relative to common usage, where "SPI" names what a plugin + * implements and "API" names the engine services it consumes. Here {@code fe-connector-spi} is the smaller + * module and holds mostly engine-provided services. The names are deliberately not being changed; read the + * content rather than the name.

    + * + *

    Types in this package deliberately avoid thrift even for data that ends up at BE (an enum NAME as a + * {@code String}, a neutral broker-address type, a thrift enum's integer VALUE as an {@code int}). Treat that + * as a local convention of this module, not as a guarantee that the connector surface is thrift-free: this + * module depends on {@code fe-connector-api}, which does use thrift types at the BE protocol boundary.

+/**
+ * The connector-agnostic, role-aware driver of incremental metastore-event sync. It is the fe-core half
+ * of the metastore-event relocation: it iterates catalogs, asks each connector that exposes a
+ * {@link ConnectorEventSource} for a batch of neutral {@link MetastoreChangeDescriptor}s, and applies
+ * them to the engine's catalog→db→table object graph and caches — the plugin never touches
+ * {@code CatalogMgr}, {@code EditLog}, or the HA state.
+ *
+ * 
    Engine/connector split (Trino-aligned). The engine owns everything stateful and replicated:
+ * the per-catalog cursor, the master/follower role, the edit-log write of the synced cursor, and the
+ * follower→master {@code REFRESH CATALOG} forward. The connector owns only the metastore fetch +
+ * message parse behind {@code pollOnce}. This mirrors the legacy {@code MetastoreEventsProcessor} role
+ * logic exactly, but the source-specific work is now behind the SPI and the type gate
+ * ({@code instanceof HMSExternalCatalog}) is replaced by a capability probe ({@code getEventSource() != null}).
+ *
+ * 
    Dormant until the flip. Only a {@link PluginDrivenExternalCatalog} whose connector exposes an
+ * event source is driven; pre-flip no such catalog exists, so this daemon is inert. At the flip the legacy
+ * poller's gate goes false and this driver takes over, and the {@code MetaIdMappingsLog} replay handler is
+ * repointed to feed THIS driver's follower cursor (see {@link #updateMasterLastSyncedEventId}).
+ *
+ * 
    Classloader. {@code pollOnce} runs under a context-classloader pin to the event source's own
+ * plugin classloader (covering the notification RPC and the JSON/GZIP deserialization), mirroring
+ * {@code PluginDrivenScanNode.onPluginClassLoader}; the daemon thread does not inherit any pin.

+/**
+ * Converts a connector-neutral {@link ConnectorExpression} residual predicate (as returned by
+ * {@code ConnectorMetadata.getSyntheticScanPredicates}) BACK into a bound Nereids {@link Expression}. It is the
+ * reverse of the forward converters {@link NereidsToConnectorExpressionConverter} /
+ * {@link ExprToConnectorExpressionConverter} (same package) and is connector-agnostic: it only maps
+ * {@code ConnectorExpression} node types to Nereids nodes — the column names and literal values come entirely
+ * from the connector's payload, so there is ZERO source-specific logic here.
+ *
+ * 
    The analysis-time rule that injects a connector's synthetic scan predicate (e.g. hudi's incremental
+ * {@code _hoodie_commit_time} window) calls this to turn each returned {@code ConnectorExpression} into a
+ * {@code LogicalFilter} conjunct, binding {@link ConnectorColumnRef}s to the scan-output {@link SlotReference}s
+ * by name.
    
+ *
+ * 
    TOTAL and FAIL-LOUD — the deliberate INVERSE of the forward converter's drop-on-unknown contract.
+ * The forward converter returns {@code null} for unrepresentable nodes because dropping a conjunct only WIDENS
+ * a write-conflict filter (safe). Here the opposite holds: dropping a conjunct from a residual SCAN predicate
+ * UNDER-filters and leaks rows the connector meant to exclude (a correctness bug). So this throws on any node
+ * outside the supported grammar, on any column reference that does not resolve to a scan-output slot, and on
+ * any non-string literal — never silently returning null.
    
+ *
+ * 
    Supported grammar (what a connector residual predicate uses today): {@link ConnectorAnd},
+ * {@link ConnectorComparison} with an order/equality operator ({@code EQ/LT/LE/GT/GE}), {@link ConnectorColumnRef}
+ * bound by name, and STRING {@link ConnectorLiteral}s. Extend the dispatch (and add a
+ * {@code ConnectorType -> Nereids DataType} mapper for typed literals) when a connector needs a wider shape.

+ * Converts a Nereids {@link Expression} tree into an engine-neutral {@link ConnectorExpression} tree for the

+ * plan rather than a legacy {@code Expr}.
+ *
+ * 
    Node matrix = the legacy iceberg conflict matrix ({@code

+ * {@link SlotReference} on one side and a {@link Literal} on the other (operands are normalised to
+ * column-on-left, the operator unchanged — mirroring legacy {@code convertNereidsBinaryPredicate}).

+ * a real concurrent-write conflict); pushing a form legacy drops would narrow it and risk a missed
+ * conflict. AND drops unconvertible conjuncts (fewer ANDed predicates = wider); OR is all-or-nothing (a
+ * dropped disjunct would narrow it). See deviations-log DV-T07b-matrix.

+/**
+ * Lowers an {@code ALTER TABLE t EXECUTE proc(...) WHERE } predicate into an engine-neutral
+ * {@link ConnectorPredicate} for a {@code DISTRIBUTED} connector procedure (today: iceberg
+ * {@code rewrite_data_files}), so the connector can scope the rewrite to the files matching the {@code WHERE}.
+ *
+ * 
    This is the procedure-side analogue of {@link WriteConstraintExtractor} (the DELETE/MERGE write-time
+ * conflict path), but with two essential differences driven by the {@code EXECUTE} grammar and the rewrite
+ * semantics:
    
+ *
+ * 
      
+ *   
    1. The WHERE arrives UNBOUND. {@code ExecuteActionCommand} never runs the Nereids analyzer over
+ *       its {@code WHERE} (only the table name is analysed), so column references are {@link UnboundSlot}s
+ *       (a bare name from the parser), not bound {@link SlotReference}s. {@link WriteConstraintExtractor} /
+ *       {@link NereidsToConnectorExpressionConverter} require bound slots and would silently drop every
+ *       unbound leaf — yielding an empty predicate and a whole-table rewrite. Here each leaf column name is
+ *       resolved directly against the target table's schema ({@link ExternalTable#getColumn}), mirroring the
+ *       legacy {@code IcebergNereidsUtils.extractColumnName} which also accepted the unbound parser form.
      2. 
+ *   
    2. Fail-loud, never widen. For a write-time conflict filter, dropping an unconvertible conjunct
+ *       only widens the filter (safe). For a user-authored rewrite {@code WHERE}, dropping a conjunct
+ *       widens the set of files rewritten — at the limit, dropping the whole {@code WHERE} rewrites the
+ *       entire table. So this converter is strictly all-or-nothing: if any part of the {@code WHERE} cannot be
+ *       represented neutrally it throws (restoring the legacy live-rewrite behaviour, which threw), rather than
+ *       producing a partial/empty predicate. The connector enforces the symmetric invariant on its side
+ *       (a conjunct it cannot push to file pruning is also a hard error, not a silent drop).
      3. 
+ * 
    
+ *
+ * 
    Node matrix mirrors {@link NereidsToConnectorExpressionConverter} (the legacy iceberg WHERE node
+ * set): {@code And}/{@code Or}/{@code Not}, the five comparisons ({@code EQ}/{@code GT}/{@code GE}/{@code LT}/
+ * {@code LE}, column-op-literal), {@code In}, {@code IsNull}, {@code Between}. Literals route through
+ * {@link ExprToConnectorExpressionConverter} so the neutral type tokens are byte-identical to the scan /
+ * conflict paths; the connector then maps them to its own dialect. The {@link ConnectorColumnRef} carries the
+ * column's real type (resolved from the table schema) — accurate rather than a placeholder — even though the
+ * iceberg connector resolves the column by name and does not read it.
    
+ *
+ * 
    Engine-neutral by construction (no {@code instanceof Iceberg}, no iceberg imports): it speaks only the
+ * neutral {@code connector.api.pushdown} vocabulary plus generic Nereids nodes.

-     * Commits object storage partition updates (e.g., for S3, Azure Blob, etc.).
-     *
-     * 
    In object storage systems, the write workflow is typically divided into two stages:
-     * 
      
-     *   
    • Upload (Stage) Phase – Performed by the BE (Backend).
-     *       During this phase, data parts (for S3) or staged blocks (for Azure) are uploaded to
-     *       the storage system.
      • 
-     *   
    • Commit Phase – Performed by the FE (Frontend).
-     *       The FE is responsible for finalizing the uploads initiated by the BE:
-     *       
        
-     *         
      • For S3: the FE calls {@code completeMultipartUpload} to merge all uploaded parts into a
-     *         single object.
        • 
-     *         
      • For Azure Blob: the BE stages blocks, and the FE performs the final commit to seal
-     *         the blob.
        • 
-     *       
      
-     *   
      • 
-     * 
    
-     *
-     * 
    This method is executed by the FE and ensures that all uploads initiated by the BE
-     * are properly committed and finalized on the object storage side.

- * Hive engine implementation of {@link AbstractExternalMetaCache}.
- *
- * 
    This cache consolidates schema metadata and Hive Metastore-derived runtime metadata
- * under one engine so callers can use a unified invalidation path.
- *
- * 
    Registered entries:
- * 
      
- *   
    • {@code schema}: table schema cache keyed by {@link SchemaCacheKey}
      • 
- *   
    • {@code partition_values}: partition value/index structures per table
      • 
- *   
    • {@code partition}: single partition metadata keyed by partition values
      • 
- *   
    • {@code file}: file listing cache for partition/table locations
      • 
- * 
    
- *
- * 
    Invalidation behavior:
- * 
      
- *   
    • {@link #invalidateDb(long, String)} and {@link #invalidateTable(long, String, String)}
- *   clear all related entries with table/db granularity.
      • 
- *   
    • {@link #invalidatePartitions(long, String, String, List)} supports partition-level
- *   invalidation when specific partition names are provided, and falls back to table-level
- *   invalidation for empty input or unresolved table metadata.
      •

-/**
- * A metastore event is a instance of the class
- * {@link NotificationEvent}. Metastore can be
- * configured, to work with Listeners which are called on various DDL operations like
- * create/alter/drop operations on database, table, partition etc. Each event has a unique
- * incremental id and the generated events are be fetched from Metastore to get
- * incremental updates to the metadata stored in Hive metastore using the the public API
- * get_next_notification These events could be generated by external
- * Metastore clients like Apache Hive or Apache Spark configured to talk with the same metastore.
- * 
    
- * This class is used to poll metastore for such events at a given frequency. By observing
- * such events, we can take appropriate action on the {@link org.apache.doris.datasource.hive.HiveExternalMetaCache}
- * (refresh/invalidate/add/remove) so that represents the latest information
- * available in metastore. We keep track of the last synced event id in each polling
- * iteration so the next batch can be requested appropriately. The current batch size is
- * constant and set to {@link org.apache.doris.common.Config#hms_events_batch_size_per_rpc}.

-/**
- * Iceberg engine implementation of {@link AbstractExternalMetaCache}.
- *
- * 
    Registered entries:
- * 
      
- *   
    • {@code table}: loaded Iceberg {@link Table} instances per Doris table mapping, each
- *   memoizing its latest snapshot runtime projection
      • 
- *   
    • {@code view}: loaded Iceberg {@link View} instances
      • 
- *   
    • {@code manifest}: parsed manifest payload ({@link ManifestCacheValue}) keyed by
- *   manifest path and content type
      • 
- *   
    • {@code schema}: schema cache keyed by table identity + schema id
      • 
- * 
    
- *
- * 
    Manifest entry keys are path-based and intentionally not table-scoped. This allows
- * shared manifests to reuse one cache entry across tables in the same catalog.
- *
- * 
    Invalidation behavior:
- * 
      
- *   
    • catalog invalidation clears all entries and drops Iceberg {@link ManifestFiles} IO cache
      • 
- *   
    • db/table invalidation clears table/view/schema entries, while keeping manifest entries
      • 
- *   
    • partition-level invalidation falls back to table-level invalidation
      •

    This class provides configuration support for using Apache Paimon with - * Aliyun Data Lake Formation (DLF) as the metastore.

    Key Characteristics: - *

      - *
    • Internally uses HiveCatalog with custom HiveConf configured for Aliyun DLF.
      • - *
    • Relies on {@link ProxyMetaStoreClient} to bridge DLF compatibility.
      • - *
    • Requires Aliyun OSS as the storage backend. Other storage types are not - * currently verified for compatibility.
      • - *
    - * - *

    Note: This is an internal extension and not an officially supported Paimon - * metastore type.

    WHY this matters: for a connector whose sys tables have no point-in-time semantics (paimon — + * the default capability), a {@code FOR TIME AS OF} (snapshot) or {@code @incr}/scan-params query + * against a plugin system table ({@link PluginDrivenSysExternalTable}) is undefined; legacy + * {@code PaimonScanNode.getProcessedTable} throws for exactly this case. Without the guard the + * scan-params / snapshot would be silently dropped and the query would return the plain sys-table + * contents, masking a user error. These tests pin that the guard fails loud (Rule 12).

    + * + *

    P6.5-T07: the guard is now CONNECTOR-CAPABILITY-AWARE. A connector reporting + * {@code supportsSystemTableTimeTravel()==true} (iceberg — whose metadata tables legally time-travel) + * lets a pinned read ({@code FOR TIME AS OF}, {@code @branch}/{@code @tag}) through to the connector, + * which retains+honors the pin; {@code @incr} is rejected for EVERY connector (undefined on a synthetic + * metadata table). Paimon keeps the default {@code false} and the original blanket rejection.

    + * + *

    Driven on a Mockito mock with {@code CALLS_REAL_METHODS} (no constructor — building a full + * {@link FileQueryScanNode} needs a harness this module lacks) and the four accessors + * ({@code getTargetTable}, {@code getScanParams}, {@code getQueryTableSnapshot}, + * {@code sysTableSupportsTimeTravel}) stubbed, so the real guard runs against controlled state. The + * guard and the capability hook are package-private exactly to enable this.

    Why this matters (Rule 9 — tests encode WHY): the {@code backends:} block (the per-backend + * scan-range detail with {@code dataFileNum/deleteFileNum/deleteSplitNum}) is universal {@link FileScanNode} + * behavior: the parent emits it unconditionally under {@code VERBOSE && !isBatchMode()} + * ({@code FileScanNode#getNodeExplainString}).

    + * + *

    MUTATION killed: re-introducing {@code && "paimon".equals(desc.getTable().getDatabase() + * .getCatalog().getType())} makes a non-paimon catalog (here {@code max_compute}) skip the block, so + * {@code "backends:"} disappears from VERBOSE EXPLAIN → {@link #verboseEmitsBackendsBlockForNonPaimonConnector} + * goes red. {@link #nonVerboseOmitsBackendsBlock} pins the surviving {@code VERBOSE} gate so a mutant that + * drops the level check (always emitting the block) is also killed.

    Why a manifest attribute and not a method on the SPI. The plugin's declared version must + * physically travel with the plugin artifact. A {@code default} method on an SPI interface cannot do that: the + * SPI interface is always loaded parent-first from the FE kernel (see + * {@link ChildFirstClassLoader#DEFAULT_PARENT_FIRST_PACKAGES} and each family's parent-first prefixes), and + * every plugin zip excludes the SPI jar, so the default body executed on a "plugin's" behalf is the kernel's + * own code. Such a check is true by construction and can never reject anything. Reading a MANIFEST attribute + * of the jar that defines the plugin's factory class reads a value that was stamped when the plugin was built. + * + *

    One number, distributed to two places

    + * + *

    Each family declares its API version once, as a maven property in its parent pom. That single property + * flows to both sides of the comparison in the same build: + *

      + *
    1. into a filtered resource inside the family's SPI module, which this class reads to learn what the + * kernel expects;
      2. + *
    2. into the {@code } of every plugin jar built from that pom, which + * {@link DirectoryPluginRuntimeManager} reads to learn what a plugin declares.
      3. + *
    + * There is no second number to keep in sync, so no synchronization test is needed. + * + *

    Naming convention (families are derived, not enumerated)

    + * + *

    A family is named by a single lower-case token, e.g. {@code connector}. Everything else follows from it: + *

      + *
    • kernel resource: {@code /META-INF/doris/connector-plugin-api-version.properties}, holding + * {@code api.version=};
      • + *
    • plugin MANIFEST attribute: {@code Doris-Connector-Plugin-Api-Version}.
      • + *
    + * A new family only has to follow the convention on both the pom side and the manager side; this class stays + * family-neutral. + * + *

    Decision rule

    + * + *

The plugin API version in + * {@code } is the contract that says which FE a given plugin may load into, + * and the rule attached to it is blunt: any change to the surface below — adding a type or a method + * just as much as removing or re-signing one — is a MAJOR change.

D8）。 + +### 1.2 三个不可妥协的不变量 + +1. **fe-connector → fe-core 单向依赖**：禁止任何 `import org.apache.doris.{catalog,common,datasource,qe,analysis,nereids,planner}`。允许 `org.apache.doris.thrift.*`（provided）和 `org.apache.doris.connector.*` / `org.apache.doris.extension.*` / `org.apache.doris.filesystem.*`。CI 必须有 grep 守门。 +2. **Image / 元数据持久化向后兼容**：旧 FE image 中保存的 `IcebergExternalCatalog`、`PaimonExternalDatabase` 等 GSON 类型必须能被新 FE 反序列化并平滑迁移到 `PluginDrivenExternalCatalog`。范本是 `PluginDrivenExternalCatalog.gsonPostProcess()` 中对 ES/JDBC 的处理（已有），需推广到所有类型。 +3. **用户可见行为不回归**：`SHOW CREATE CATALOG`、`SHOW TABLE STATUS`、`information_schema.tables`、`EXPLAIN` 输出、错误信息、catalog `type` 字段、`engine` 字段（`getEngine` / `getEngineTableTypeName`）需保留旧名字。已经在 `PluginDrivenExternalTable.getEngine()` 用 switch 兜底，迁移过程中维护这个 switch。 + +--- + +## 2. 现状审视：先解决的 SPI 设计缺口 + +迁移之前必须先把 SPI 补齐到能承载所有六个连接器，否则边迁边补会被反复打回。 + +### 2.1 必须新增的 SPI 能力 + +> 全部加在 `fe-connector-api` 下；保持 `default` 方法策略以让现有连接器零迁移成本。 + +| 能力 | 当前在哪 | 计划新增的 SPI | +|---|---|---| +| **DDL info** —— `CreateTableInfo`/`PartitionDesc`/`DistributionDesc` 等都是 nereids 类型，连接器看不到 | `IcebergMetadataOps.createTable(CreateTableInfo)`、`HiveMetadataOps.createTable(CreateTableInfo)` | 在 `ConnectorTableOps` 增加 `createTable(session, ConnectorCreateTableRequest)`，引入 `ConnectorCreateTableRequest`、`ConnectorPartitionSpec`、`ConnectorBucketSpec` 三个 POJO；fe-core 侧加 `CreateTableInfoToConnectorRequestConverter` | +| **Procedures / Actions** —— Iceberg 10 个 `IcebergXxxAction` 通过 `BaseIcebergAction` 调用 `IcebergMetadataOps.commit*` | `datasource/iceberg/action/*` | 新增 `ConnectorProcedureOps`（`listProcedures`、`callProcedure(name, args)`），fe-core 侧 `ExecuteActionCommand` 走通用 dispatch | +| **元数据失效事件**（HMS notification）—— 21 个 `MetastoreEvent` 类 | `datasource/hive/event/MetastoreEventsProcessor` 调用 fe-core 的 `ExternalMetaCacheMgr.invalidate*` | 选项 A：把 event 处理整体搬到 `fe-connector-hms`，通过 `ConnectorContext.getMetaInvalidator()`（新增）回调 fe-core。选项 B：只把"轮询 HMS 拿事件流"和"解析事件"放连接器，"分发失效"留 fe-core。**推荐 A**（决策点 D4） | +| **事务管理器** | `transaction/HiveTransactionManager`、`IcebergTransactionManager` | 新增 `ConnectorTransactionFactory`（已存在的 `PluginDrivenTransactionManager` 当骨架），把 `HiveTransactionMgr` 内部状态搬进连接器实现 | +| **MVCC 快照** | `IcebergMvccSnapshot`、`PaimonMvccSnapshot` | 新增 `ConnectorMvccSnapshot` 类型，`ConnectorMetadata.beginQuery(session) -> ConnectorMvccSnapshot`；fe-core 侧 `MvccSnapshot` 接口由连接器提供实现 | +| **Vended credentials** | `IcebergVendedCredentialsProvider`、`PaimonVendedCredentialsProvider` | `ConnectorCapability.SUPPORTS_VENDED_CREDENTIALS` 已存在；新增 `ConnectorCredentials getCredentialsForScan(session, ConnectorScanRange)` | +| **Sys-tables / metadata-tables** | `IcebergSysExternalTable`、`PaimonSysExternalTable` | 在 `ConnectorTableOps` 增加 `listSysTableTypes()` / `getSysTableSchema(...)` | +| **Statistics 写入**（`ANALYZE TABLE`）| `HMSExternalTable.createAnalysisTask` | 把 `ExternalAnalysisTask` 改为只调 `ConnectorStatisticsOps`；新增 `setColumnStatistics` 方法 | +| **写路径 sink 配置**（不是数据本身，BE 写）|

列举**（给 TVF / SHOW PARTITIONS 用）| `MaxComputeExternalCatalog`、`PaimonExternalCatalog`、`HMSExternalCatalog` 各自的 `listPartition*` | 新增 `ConnectorTableOps.listPartitions(session, handle, filter)` / `listPartitionValues(session, handle, columns)` | + +### 2.2 推荐放弃 / 推迟的 SPI 演进 + +- **不要**为 ScanRange 引入更多多态——`PluginDrivenScanNode` extends `FileQueryScanNode` 的桥接策略已经验证可行（ES/JDBC）。 +- **不要**抽象 `Resource` 兼容层——旧 resource-backed catalog 用 `gsonPostProcess` 回填 `type` 已足够。 + +### 2.3 SPI 改动的版本号管理 + +> ⚠️ **已被取代（2026-07-29）**：`ConnectorProvider.apiVersion()` 与

**~25 周**（不含 lakesoul / RemoteDoris 等遗留类型清理）。 + +### 3.1 阶段 P0：SPI 缺口补齐 + +**目标**：让 §2.1 表里所有缺口都有对应 SPI 类型/方法在 `fe-connector-api`，且至少一个连接器的现有实现已经能在 `default` 模式下正常工作。 + +**任务**： + +1. 新增 SPI 类型：`ConnectorCreateTableRequest`、`ConnectorPartitionSpec`、`ConnectorBucketSpec`、`ConnectorProcedureOps`、`ConnectorMvccSnapshot`、`ConnectorCredentials`、`ConnectorMetaInvalidator`（在 SPI 包）。 +2. 在 `ConnectorTableOps`、`ConnectorMetadata`、`ConnectorContext` 上新增对应 default 方法。 +3. 在 `fe-core` 侧加 converter：`CreateTableInfoToConnectorRequestConverter`、`ConnectorRequestToCreateTableInfoConverter`（如果需要双向）。 +4. 给 `PluginDrivenExternalCatalog` / `PluginDrivenExternalTable` 加上分发：CREATE TABLE / EXECUTE PROCEDURE / ANALYZE / SHOW PARTITIONS 都路由到 SPI。 +5. 更新 `ConnectorPluginManager` 文档：列出"新 SPI 在 v1 中以 default 方法形式添加，连接器无需更新版本号"。 +6. CI 守门：grep 脚本 `tools/check-connector-imports.sh` 在 `fe-connector/**/*.java` 中扫描禁用 import 列表，作为 maven 的 `enforcer` 步骤。 + +**完成判据**： +- `mvn -pl fe-connector verify` 全绿。 +- JDBC、ES 仍正常（回归）。 +- 一条 fake 连接器（在测试目录下）能在不实现新 SPI 的情况下编译并工作。 + +### 3.2 阶段 P1：重复清理 + scan-node 收口 + +**目标**：在迁连接器之前先把已经造成混乱的旧代码清掉，并把 `PhysicalPlanTranslator` 的 scan-node 分支从 7 个减到 1 个。 + +**任务**： + +1. 删除 fe-core 旧的 `datasource/jdbc/client/Jdbc*Client.java` 13 个文件 + `JdbcFieldSchema.java`。删除前 grep `org.apache.doris.datasource.jdbc.client` 在 fe-core 内被谁引用——预期只有 `JdbcExternalCatalog` 等已经走 SPI 的代码会引用，需要它们也搬走或改路径。 +2. 删除 fe-core 重复的 `PaimonPredicateConverter`、`McStructureHelper`，让 fe-core 通过 SPI 桥接（如果 fe-core 真的需要这两个工具，应该挪到通用工具包；但更可能它们是 leak，可直接删）。 +3. **收口 `PhysicalPlanTranslator.visitPhysicalFileScan`**：把所有 `instanceof HMSExternalTable / IcebergExternalTable / TrinoConnectorExternalTable / MaxComputeExternalTable / LakeSoulExternalTable` 分支统一改为： + - 若 `table instanceof PluginDrivenExternalTable` → 走 `PluginDrivenScanNode.create(...)` + - 兜底（迁移期）保留老分支 + - 在每个连接器迁移完成时（P3–P7）删掉对应分支。 +4. 把 `visitPhysicalHudiScan` 改为内部委托 `PluginDrivenScanNode` 处理增量场景（这里是 `getScanNodeProperties()` 的扩展）。 +5. 把 `LogicalFileScan.computeOutput` 中的 `instanceof IcebergExternalTable` / `HMSExternalTable` 改成通过 `ConnectorMetadata.getTableSchema` 拿额外列（metadata column）。 + +**完成判据**： +- `PhysicalPlanTranslator` 不再 `import` 任何具体 `*ExternalTable` 类（除迁移期 fallback）。 +- 全量回归 P0 通过。 + +### 3.3 阶段 P2：trino-connector 迁移（先开荒） + +**为什么先做它**： + +- fe-core 侧只有 6 个文件 + `source/`，且只有 2 处反向 `instanceof` 引用。 +- fe-connector-trino 已经有 13 个文件，scan/predicate/plugin loader/services provider 都已搬好。 +- 没有 transaction、没有 event、没有 ACID。 +- 失败的爆炸半径最小，可以把整个 migration playbook 跑一遍。 + +**任务清单**（**这套清单就是后续每个连接器都要走的 playbook**）： + +1. **代码层面**： + - 把 `datasource/trinoconnector/TrinoConnectorExternalCatalog/Database/Table` 中尚未在 connector 模块中的逻辑搬过去（schema cache、plugin loader 关闭、property 校验）。 + - 在 `TrinoConnectorMetadata` 实现 `getTableSchema` / `listTableNames` / `getTableHandle` / `applyFilter` / `applyProjection`（多数已在）。 + - `TrinoScanPlanProvider` 已实现 `planScan` —— review 一遍 split 数量、Thrift desc 字段。 +2. **桥接层面**： + - `CatalogFactory.SPI_READY_TYPES` 加入 `trino-connector`。 + - `PhysicalPlanTranslator` 删除 `instanceof TrinoConnectorExternalTable` 分支。 + - `PluginDrivenExternalTable.getEngine() / getEngineTableTypeName()` 加 `trino-connector` 分支。 + - 检查 `TableIf.TableType.TRINO_CONNECTOR_EXTERNAL_TABLE` 是否仍需保留作为 GSON 兼容（**保留**，并在 `gsonPostProcess` 中迁移到 `PLUGIN_EXTERNAL_TABLE`）。 +3. **持久化兼容**： + - 在 `PluginDrivenExternalCatalog.gsonPostProcess` 中加 `trinoconnector → plugin` 的 logType 迁移（已有 ES/JDBC 范本）。 + - 在 `ExternalCatalog.registerCompatibleSubtype` 注册 `TrinoConnectorExternalCatalog` → `PluginDrivenExternalCatalog`。 +4. **测试**： + - 给 `fe-connector-trino` 加单元测试（mock Trino plugin），覆盖 schema 解析、predicate 转换、scan plan。 + - regression-test 里新增 `trino_connector_migration_compat` 测试：模拟旧 FE image 反序列化。 +5. **打包**： + - 验证 `mvn package -pl fe-connector-trino` 生成的 `plugin.zip` 内容、`lib/` 排除项是否完整。 + - 文档：在 `docs-next/` 添加 trino-connector 插件安装步骤。 +6. **删除 fe-core 旧代码**（迁移完成的最后一步）： + - `rm -rf fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/` + - `CatalogFactory.java` 移除 `case "trino-connector": ...` + - 删除 `import` 失败处全部走 SPI 改造。 + +**风险点**：Trino 插件加载（`TrinoPluginManager` 在连接器内部）要确认 classloader 隔离不会破坏 fe-core 现有 Trino 用法。如果有 BE 端共用 Trino 二进制的情况，需要复核。 + +### 3.4 阶段 P3：hudi 迁移 + +**特殊性**：hudi 没有自己的 `*ExternalCatalog`，它寄生在 HMS 上——表是 `HMSExternalTable.dlaType=HUDI`。 + +**任务**： + +1. **重构 DLA 模型**：在 SPI 层显式建模"一个 HMS 表实际是 hudi 表"。两个选项： + - **选项 A**（推荐）：在 `ConnectorTableSchema.tableFormatType` 上做约定值 `HUDI` / `ICEBERG` / `HIVE`，由 HMS 连接器探测后填充；Doris 侧 `PluginDrivenExternalTable` 根据这个值决定走 `PhysicalHudiScan` 还是 `PhysicalFileScan`。 + - **选项 B**：hudi 作为独立 catalog type，但 catalog 内部委托 HMS 连接器拿元数据。 + -

ORC/Parquet（FILE_S3）reader 只解析 canonical `AWS_ACCESS_KEY`/`AWS_SECRET_KEY`/`AWS_ENDPOINT`/`AWS_REGION`/`AWS_TOKEN`（`s3_util.cpp:146-150`）→ 私有 object-store 桶 native 读拿不到凭据 → **403/AccessDenied**。公有桶 + JNI 路不受影响（序列化 paimon `Table` 自带 `FileIO`）。裸 `AWS_*`/`access_key`（无 `s3.` 前缀）被前缀过滤整个丢弃。区别于已修两缝：FIX-STORAGE-CREDS 修 *catalog FileIO* 缝、FIX-REST-VENDED 修 *vended(REST) scan→BE* 缝。 + +**根因**：legacy `PaimonScanNode.getLocationProperties:650-652` **仅**返回 `backendStorageProperties`（`:176` = `CredentialUtils.getBackendPropertiesFromStorageMap(storagePropertiesMap)`，catalog 已解析的 `StorageProperties` map）。`getBackendPropertiesFromStorageMap` 逐 `StorageProperties` 调 `getBackendConfigProperties()` → canonical 键（`AbstractS3CompatibleProperties:106-120` 发 `AWS_*`；`HdfsProperties:163-200` 发已解析

The `fileFormat` string is used for `formatType` only on the **native** branch (`:174-178`, +where it is already the real orc/parquet). So changing the JNI/count `fileFormat` from `"jni"` to the +real format leaves JNI routing untouched and only corrects the inner `fileDesc.fileFormat` BE consumes. + +## Legacy parity +`paimon/source/PaimonScanNode.setPaimonParams`: `rangeDesc.setFormatType(FORMAT_JNI)` (routing) **and** +`fileDesc.setFileFormat(fileFormat)` (`:288`) where +`fileFormat = getFileFormat(paimonSplit.getPathString())` (`:259`) = +`FileFormatUtils.getFileFormatBySuffix(path).orElse(source.getFileFormatFromTableProperties())`. For a +JNI whole-`DataSplit`, `getPathString()` resolves to the first data file's name, and the fallback is the +table `file.format` property. For a homogeneous paimon table (one `file.format` per table) that equals +`defaultFileFormat`. So `defaultFileFormat` is the correct, legacy-faithful value (and is exactly BE's +own `FILE_FORMAT` resolution source). + +## Design +1. **`buildJniScanRange`**: `.fileFormat("jni")` → `.fileFormat(defaultFileFormat)` (the parameter it + already receives, currently ignored). Covers both the non-DataSplit metadata-split call + (`planScanInternal:357`) and the DataSplit JNI call (`:419`). +2. **`buildCountRange`**: add a `String defaultFileFormat` parameter; `.fileFormat("jni")` → + `.fileFormat(defaultFileFormat)`; thread `defaultFileFormat` from the call site (`planScanInternal:430`, + where it is in scope). +3. **`PaimonScanRange.Builder` default (`:244`)**: change `private String fileFormat = "jni"` → + `private String fileFormat = ""`. Every production caller sets `fileFormat` explicitly, so the default + is currently dead — but `"jni"` is the very invalid value this fix removes; an empty default is the + safe one (BE's `!file_format.empty()` guard then **skips** the backfill rather than ever injecting an + invalid format, and the native `formatType` branch only matches real `orc`/`parquet`). Pure safety net, + no behavioral change for any existing path. + +### Divergence note (accepted) +`defaultFileFormat` is the table's `file.format` option; legacy derives the JNI format path-suffix-first +(first data file), table-prop fallback. These differ only for a **mixed-format** table (e.g. after +`ALTER ... file.format` leaves old-format files), which paimon does not produce per-table; the table +option is the more correct per-table hint for the whole-split BE backfill. The native path keeps its +per-file suffix derivation (`buildNativeRange:450`, unchanged). + +## Implementation Plan +1. `buildJniScanRange`: `"jni"` → `defaultFileFormat`. +2. `buildCountRange`: add param + use it; update call site `:430`. +3. `PaimonScanRange.Builder.fileFormat` default `"jni"` → `""`. +4.

This matches the migration end-state where +`hive-catalog-shade` and fe-core's Hadoop stack are removed (user-confirmed 2026-06-12): a parent-first / `provided` +approach would break the moment fe-core sheds hadoop. Three coordinated changes: + +1. **Packaging** (`fe-connector-paimon/pom.xml`): add **`hadoop-aws`** only (groupId+artifactId; version + `${hadoop.version}`=3.4.2 + exclusions inherited from `fe/pom.xml` dependencyManagement). Empirically, the plugin + lib already bundles `hadoop-client-api-3.4.2.jar` (transitive) carrying `FileSystem` / hdfs `DistributedFileSystem` + / `SecurityUtil` / `DNSDomainNameResolver`; the ONLY FS impl missing from the child was `S3AFileSystem` + (`hadoop-aws`). So adding `hadoop-aws` completes the child closure. (Earlier draft also added `hadoop-hdfs` — dropped: + in Hadoop 3.x `DistributedFileSystem` lives in `hadoop-hdfs-client`/`hadoop-client-api`, NOT `hadoop-hdfs`, so it was + dead weight + extra duplication.) `S3AFileSystem`'s AWS SDK v2 classes (`software.amazon.awssdk.*`, the heavy + `:bundle` excluded in depMgmt) are not in the child and resolve from the FE parent classpath as a SINGLE copy → a + cross-loader reference but not a split (only one copy exists). `hive-common` stays bundled (child); + `org.apache.hadoop` stays child-first; no parent-first list change. + +2. **Configuration classloader** (`PaimonCatalogFactory.buildHadoopConfiguration`): after `new Configuration()`, call + `conf.setClassLoader(PaimonCatalogFactory.class.getClassLoader())`. Forces `Configuration.getClass("fs..impl")` + to resolve FS impls from the plugin loader (handles the `fs.s3a.impl`/`fs.hdfs.impl` config-driven path). + +3. **Thread-context CL pin** (`PaimonConnector.createCatalogFromContext`, the single chokepoint for all 5 flavors): + wrap the `executeAuthenticated(() -> CatalogFactory.createCatalog(...))` call in a + `setContextClassLoader(getClass().getClassLoader())` / restore-in-`finally`, mirroring `JdbcConnectorClient`.

The one-time class + resolutions + `SecurityUtil.` happen here (first FS touch), so pinning creation suffices for the observed + failures; later FS ops reuse the cached `FileSystem` / already-loaded classes. + +Why all three: #1 alone → ServiceLoader still reads parent (thread-context) service files → ServiceConfigurationError. +#3 alone → child lacks `S3AFileSystem` → "No FileSystem for scheme s3a". #2 covers the config-driven `getClass` path +that uses `Configuration.classLoader` (not the thread-context CL).

No `HiveConf` classloader change (#2 is scoped to `buildHadoopConfiguration`, filesystem/jdbc only). Flag for hms/dlf cutover e2e. +- **Version skew**: `${hadoop.version}` mirrors fe-core, so the bundled FS impls match `hadoop-common`/paimon expectations. +- **Local verification gap**: the full fix is only provable by the docker external suite (CI-gated). Local proof = + build + assert plugin `lib/` contents + connector UTs + the mechanism analysis above. + +## Test Plan +### Unit Tests +- `PaimonCatalogFactoryTest` must stay green; the existing `buildHadoopConfiguration*` test still asserts S3 prefix / + raw-key behavior (setClassLoader is orthogonal).

Its "loader-global +static cache" argument is also off — `FileSystem.SERVICE_FILE_SYSTEMS` / `Configuration.CACHE_CLASSES` are statics of +the *child's* `FileSystem`/`Configuration` class (per-loader), and are populated correctly under the #3 pin.

The 1-arg `normalizeStorageUri` becomes a delegate with a `null` +token → `effective == static` → **byte-identical to current behavior** (the 4 existing fe-core tests stay green). + +### SPI (`fe-connector-spi/ConnectorContext`) +Add the overload as a `default` that ignores the token (other connectors have no vended creds), so it is +a no-op extension for every non-paimon connector: + +```java +default String normalizeStorageUri(String rawUri, Map rawVendedCredentials) { + return normalizeStorageUri(rawUri); // ignore token; falls to the existing default (returns rawUri) +} +``` + +### Connector (`PaimonScanPlanProvider`) +Thread the once-per-scan vended token to the normalize sites: +1. `normalizeUri(String rawUri, Map vendedToken)` → `context.normalizeStorageUri(rawUri, vendedToken)` (null-context → rawUri, unchanged). +2. `buildNativeRange(...)` / `buildNativeRanges(...)`: add a `Map vendedToken` parameter; pass it to both `normalizeUri` calls (data file + DV). +3. `planScanInternal`: compute `vendedToken = (context != null) ? extractVendedToken(table) : Collections.emptyMap();` **once** (next to the `cppReader` flag) and pass it into `buildNativeRanges` at the call site (`:404`). + +`extractVendedToken(table)` is empty for non-REST (FileIO gate) → the 2-arg call degrades to the static +path → **non-REST scans are byte-unchanged**. It is computed **once per `planScan` invocation** (not per +file/sub-range — `validToken()` may refresh the token), separate from the existing +`getScanNodeProperties:558` extraction (two independent extractions; this is a pre-existing property of +the two-method plugin SPI, not introduced here). URI normalization is **invariant under token refresh** +— `validateAndNormalizeUri` consumes only scheme/bucket/key, never the access-key/secret/token — so the +two extractions can never disagree on the normalized URI (red-team gap5). It is NOT wrapped in +`executeAuthenticated` (parity: legacy did not wrap the FileIO/cred path; the existing +`getScanNodeProperties:558` call is also unwrapped). The pinned `resolveScanTable` table carries the same +`RESTTokenFileIO` reference as the base (verified: `AbstractFileStoreTable.copy` preserves `fileIO`), so +the token matches legacy's `source.getPaimonTable()` (red-team S5c). + +## Implementation Plan +1. SPI: add the `normalizeStorageUri(uri, token)` default to `ConnectorContext`. +2. fe-core: add `buildVendedStorageMap` helper; refactor `vendStorageCredentials`; add 2-arg override; make 1-arg delegate. +3. Connector: thread `vendedToken` (steps 1–3 above). +4. Tests (below). +5. Build SPI → fe-core → connector; checkstyle; import-gate. + +## Risk Analysis +- **Behavior change for non-REST**: none — empty token → static-map path, identical to today. +- **Behavior change for REST native**: was a hard throw → now normalizes via vended map (the fix). Vended + *replaces* static (legacy parity); REST static is empty so no regression for any non-REST flavor. +- **Fail-loud preserved**: REST + bad/empty token → `buildVendedStorageMap` returns null → static (empty) + → `LocationPath.of` throws (legacy also fails loud here). The normalize path stays fail-loud; the + BE-creds path (`vendStorageCredentials`/`getBackendStorageProperties`) stays fail-soft — unchanged asymmetry. +- **Perf**: for REST scans the typed map is rebuilt per normalize call (per file + per DV + per sub-range) + rather than once-per-scan as legacy did. The token is tiny; the empty-token short-circuit means non-REST + pays nothing. Behavior is identical; only re-derivation frequency differs. Noted as a minor, accepted + divergence (a once-per-scan cache would need extra SPI surface or an opaque handle — disproportionate to + a BLOCKER hotfix; revisit only if profiling flags it). +- **Other connectors**: untouched (SPI default ignores the token; only paimon calls the 2-arg). + +## Test Plan + +### Unit Tests +**fe-core — `DefaultConnectorContextNormalizeUriTest`** (the actual bug & fix): +- `vendedRestCredentialsNormalizeUnderEmptyStaticMap`: context with an **empty** static supplier (the REST + case) + a vended token carrying oss creds (`oss.access_key/secret_key/endpoint`) → `normalizeStorageUri( + "oss://bkt/.../part-0.parquet", token)` returns `s3://bkt/.../part-0.parquet`. **This is the gap that hid + the bug twice.** MUTATION: ignoring the token (old static-only path) → throws → red. +- `emptyTokenUnderEmptyStaticStillFailsLoud`: same empty-static context, **empty** token → `normalizeStorageUri( + uri, emptyMap)` throws `RuntimeException` (proves the fix is the token, not a swallow; and that fail-loud + is intact when there is genuinely no cred). +- `staticMapPathUnaffectedByEmptyToken`: oss-static context + empty token → still rewrites oss→s3 (regression + guard for non-REST; the 2-arg must fold to the static path). +- Existing 4 tests (1-arg) remain unchanged (1-arg now delegates with null token). + +**connector — `PaimonScanPlanProviderTest`** (the threading): +- Extend `RecordingConnectorContext`: override **only** the 2-arg `normalizeStorageUri(uri, token)` so it + (a) sets `lastVendedToken = token`, (b) increments `normalizeCount` once, (c) does the oss→s3 rewrite; + then make the existing 1-arg override **delegate** to `normalizeStorageUri(rawUri, null)` (single source; + no recursion — the 2-arg does the rewrite directly, never calls the 1-arg). After the connector switches + to the 2-arg call, the connector dispatches straight to this 2-arg override (NOT via the SPI default → + 1-arg), so `normalizeCount`/rewrite are driven by the 2-arg override.

-Dexec.skip=true -DskipTests package`。 + 两层原因——① `fe-connector-hms` 编译需要 `fe-connector-hms-hive-shade` 的 shade 产物，shade 绑在 + `package` 阶段，**冷缓存**下 `test-compile` 拿不到（缓存热时能过，所以这个坑时隐时现）； + ② 禁缓存才能保证测的是真实产物，见上一节。 +2. **pom 里的 `` 元素名与 Java 侧的派生规则没有构建期检查**（XML 元素名不能插值）。 + 四个期望字面量钉在 `ApiVersionGateTest` / `PluginApiVersionWiringTest` 里供评审对照。见设计 §14.2。 +3. **`information_schema.extensions` 的 version 列不是 NULL**，而是全表恒等于 FE 构建号 `1.2-SNAPSHOT` + （ASF 父 pom 的 `addDefaultImplementationEntries` 自动写入），因此设计 §8 的"顺带项"已作废为 no-op。 +4. **es / trino 的 plugin-zip 漏排除 `fe-filesystem-api` 已一并修好**（owner

`options()/getOptions()`；`ConnectorCapability.SUPPORTS_SCAN_PARAM_OPTIONS` +（paimon 声明）；`PluginDrivenExternalTable.supportsScanParamOptions()`；`BindRelation.validateOptionsTarget` +改成**能力驱动**（不再 `instanceof PaimonExternalTable`）。 + +**⚡ 上游两条改动本分支「结构上已覆盖」，无需移植**（这是本轮最大的省力点）： +1. `LogicalFileScan.initialSelectedPartitions` → `SelectedPartitions.NOT_PRUNED`：我们的 ctor 早已按 + **本引用自己的版本** `MvccUtil.getSnapshotFromContext(table, tableSnapshot, scanParams)` 取分区， + 而显式 pin 分支返回**空分区图**（= scan-all），效果等价。 +2. `LogicalFileScan.computeOutput` 的 `getFullSchema(scanParams)` 臂：`computePluginDrivenOutput()` + 已走同一条版本感知 schema 解析。 +3. 上游 `TableScanParams.getOrResolveMapParams`（每 relation 只解析一次）：我们由 + `StatementContext.versionKeyOf` 提供 —— key 含 `sp.getMapParams()`，所以 +

`PaimonConnectorMetadata.applySnapshot` 对 **sys handle** 不再原样返回，改为透传 scan options + （@incr / @options 都经这条），并调 `validateSystemTableOptions` 拒掉系统表包装器扛不动的 + `scan.file-creation-time-millis`。 + +### D. 顺带的独立修复（3 项） +1. `PaimonIncrementalScanParams.applyResetsIfIncremental` 的 null 重置从 2 个键 + （`scan.snapshot-id`/`scan.mode`）扩到**整个 inherited read-state family**（含各 fallback 键）—— + base 表可以合法持久化 `scan.tag-name`/`scan.timestamp-millis`，与 `incremental-between` 合并会抛或读错版本。 +2. `$binlog@incr` 的 `COUNT(*)` 下推否决：binlog reader 把 UPDATE_BEFORE/AFTER 打包成 1 行， + DataSplit 的物理 merged 行数不是合法 `COUNT(*)`。 +3. `getSysTableHandle` 的 forceJni 集合从 `binlog/audit_log` 扩到含 `row_tracking`， + 并统一到 `PaimonScanParams.requiresPaimonReader`（单一事实来源）。 + +### E. 3 项**有意不移植 / 反向裁决**（Rule 7/12，务必别在下一轮又"补回来"） + +| 项 | 判断

Goals +- Restore the **per-user Iceberg REST session-credential** feature that upstream `#63068` (`e545f1ad08a`) added and that the 2026-07-09 P6 rebase dropped (its iceberg consumer collided with the fe-core→SPI move). +- Do it **on the P6 catalog-SPI architecture** (iceberg lives in `fe/fe-connector/fe-connector-iceberg`), not the old fe-core tree. +- Be **aligned with Trino's actual model**: the per-query credential rides the connector session; the connector alone decides per-user vs shared; the iceberg integration seam is `org.apache.iceberg.catalog.SessionCatalog.SessionContext` (fixed by iceberg, shared with Trino). +- Preserve behavioral parity with #63068's semantics (fail-closed when `session=user` and no credential; per-user cache bypass; `access_token` + `token_exchange` modes). + +## 2. Non-goals +- No change to the **retained generic base** (MySQL-auth capture, `ConnectContext`/`SessionContext`/`DelegatedCredential`, FE-forward thrift 1004-1007, `ConnectProcessor`/`FEOpExecutor`). It already works (research note A7) — we build on it. +- No **BE** changes (this is FE metadata/auth only). +- Not adding a Trino-style **signed subject JWT** (`sub=`) in this pass — #63068 passes the OIDC token verbatim; Trino additionally signs. We match #63068 and record signing as a future Trino-parity item (Decision D6). +- No new credential *ingress* channels beyond what the retained MySQL-auth path already captures. +- Non-REST iceberg catalogs (hive/glue/hadoop metastore) and all other connectors (paimon/jdbc/es/maxcompute) are untouched at runtime. + +## 3. Constraints +- **User directive:** FE-only, align with Trino, design-doc-first (this doc) before implementation. +- **Module boundary:** `fe-connector-iceberg` **must not import fe-core.** The credential must cross into the connector through a **neutral SPI type**, never fe-core `DelegatedCredential`/`SessionContext`. +- **Byte/behavioral parity** with #63068 for the fail-closed and cache-bypass semantics (they are security-relevant). +- **Iceberg seam is fixed:** we depend on the same `iceberg-core` `RESTSessionCatalog` + `SessionCatalog.SessionContext(sessionId, identity, credentials, properties, wrappedIdentity)` that Trino uses. + +## 4. Background (one paragraph) +`#63068` captured a user's OIDC/JWT/SAML token at MySQL login into `ConnectContext.sessionContext` (a `DelegatedCredential`), forwarded it across FE nodes via thrift, and — at iceberg metadata time — built an iceberg `SessionContext` and routed through a per-user `RESTSessionCatalog` instead of the shared catalog, while bypassing the shared FE name caches. All of that credential *plumbing* is **generic and still present** on this branch; only the **iceberg consumer** (3 classes + routing + REST props + cache-bypass hooks) was deleted, and it was written against the pre-P6 fe-core iceberg tree. + +--- + +## 5. Architecture overview + +Three layers. The credential travels: **retained base → SPI session → connector**. + +``` + (RETAINED, unchanged) (NEW: FE bridge) (NEW/RE-MIGRATED: connector) + MySQL auth → DelegatedCredential fe-connector-iceberg + → ConnectContext.sessionContext ──► ConnectorSessionBuilder ──► ConnectorSession + (thrift-forwarded across FE) .from(ctx) copies cred .getDelegatedCredential() (neutral DTO) + into neutral SPI DTO │ + ▼ + IcebergSessionCatalogAdapter (re-migrated) + .toIcebergSessionContext(cred, mode) + → org.apache.iceberg…SessionCatalog.SessionContext + │ + ▼ + shared RESTSessionCatalog.asCatalog(ctx)/asViewCatalog(ctx) + │ + ▼ + Iceberg REST server (per-user authz + vended creds) + (RETAINED hook, re-added) ExternalCatalog.shouldBypassTableNameCache(ctx) ⇒ per-user requests skip shared FE caches +``` + +**Key adaptation vs #63068:** the decision + routing move from fe-core `IcebergMetadataOps`/`IcebergUtils` (which read `SessionContext.current()` off a thread-local) into the **connector**, driven by the **credential carried on `ConnectorSession`** (injected once in `buildConnectorSession`). This is both P6-correct (iceberg is now an SPI connector) and Trino-aligned (Trino reads `session.getIdentity().getExtraCredentials()`). + +--- + +## 6. Design decisions (please review) + +### D1 — Opt-in mechanism: **SPI capability flag `SUPPORTS_USER_SESSION`** (recommended) vs Trino's config-only +- **Trino:** no capability flag; every connector universally receives `extraCredentials`; opt-in is purely the iceberg connector's `session=user` config. +- **#63068 / memory plan:** an explicit gate. +- **Recommendation: add `ConnectorCapability.SUPPORTS_USER_SESSION`**, declared by the iceberg connector only when `iceberg.rest.session=user`. Rationale: (a) matches the established Doris pattern (every other cross-cutting behavior — `SUPPORTS_VIEW`, `SUPPORTS_SHOW_CREATE_DDL`, … — is a capability replacing a legacy `instanceof`); (b) **least-privilege**: the FE injects the user's delegated credential into a `ConnectorSession` *only* for connectors that declare they consume it, so a JDBC/ES/hive-iceberg session never carries the OIDC token it would never use (a security improvement over Trino's universal pass-through). The capability gates **FE injection**; the connector's `iceberg.rest.session` config still governs per-user-vs-shared *within* iceberg. Net: capability = "may receive a credential"; config = "how iceberg uses it". +- *If you prefer strict Trino parity* we drop the flag and always inject; call it. + +### D2 — Where the credential rides: **on `ConnectorSession`** (recommended) vs threading `SessionContext` through methods +- **Recommendation: put it on `ConnectorSession`** and inject once in `PluginDrivenExternalCatalog.buildConnectorSession()` (the single funnel for ~25 call sites). This is Trino's exact shape (`ConnectorSession.getIdentity().getExtraCredentials()`) and avoids #63068's per-method `SessionContext` overloads (which made sense in fe-core but would pollute the whole SPI surface). All connector ops already receive a `ConnectorSession`. + +### D3 — Neutral SPI credential DTO +- Add `ConnectorDelegatedCredential` in `fe-connector-api` (fields mirror fe-core `DelegatedCredential`: `Type {ACCESS_TOKEN, ID_TOKEN, JWT, SAML}`, `String token`, `OptionalLong expiresAtMillis`). `ConnectorSession.getDelegatedCredential(): Optional`. fe-core maps its `DelegatedCredential` → this DTO in the builder. The connector maps this DTO → iceberg OAuth2 keys (re-migrated `IcebergDelegatedCredentialUtils`). + +### D4 — Session routing location: **the connector** (recommended) +- Re-migrate `IcebergUserSessionCatalog` (capability seam) + `IcebergSessionCatalogAdapter` (Doris↔iceberg bridge) + `IcebergDelegatedCredentialUtils` into `fe-connector-iceberg`. The connector's catalog-ops layer (today `CatalogBackedIcebergCatalogOps`, wrapping one shared `Catalog`) becomes session-aware: for a REST flavor with `session=user` + a per-request credential, it builds the iceberg `SessionContext` and calls the shared `RESTSessionCatalog.asCatalog(ctx)`/`asViewCatalog(ctx)`; otherwise the existing shared path. **The `RESTSessionCatalog` stays a single shared instance** (never one-per-user) — exactly Trino and #63068. + +### D5 — Cache bypass: keep #63068's model, driven by the SPI capability + credential +- Re-add `ExternalCatalog.shouldBypassTableNameCache(SessionContext)` (default false) + the `ExternalDatabase` live-path rerouting. On the current SPI, the REST catalog is a `PluginDrivenExternalCatalog`; the override returns true when the connector declares `SUPPORTS_USER_SESSION` **and** the session carries a credential. Under `session=user` the REST server returns per-user metadata, so the shared (catalog+name-keyed, not user-keyed) db/table/view caches must be bypassed to avoid cross-user leakage. + +### D6 — Token handling: `access_token` (verbatim bearer) + `token_exchange` (typed key); **no signed subject JWT** this pass +- Match #63068 exactly (`iceberg.rest.oauth2.delegated-token-mode`). Trino additionally mints a `sub=` JWT in `session=user`; that matters only if the REST server must trust a *Doris-asserted* identity rather than the client's own OIDC token. Record as a **future Trino-parity follow-up**, out of scope here. + +--- + +## 7. Detailed design + +### 7.1 SPI layer — `fe-connector-api` +- **`ConnectorDelegatedCredential`** (new): immutable DTO. `enum Type { ACCESS_TOKEN, ID_TOKEN, JWT, SAML }`; `getType()`, `getToken()`, `getExpiresAtMillis(): OptionalLong`, `isExpired(now)`. +- **`ConnectorSession`** (edit): `default Optional getDelegatedCredential() { return Optional.empty(); }` + a stable `getSessionId(): String` if not already derivable (needed as the iceberg `SessionContext.sessionId()` — the AuthSession cache key; must equal the forwarded id). *(Confirm whether `getQueryId()` suffices or a session-scoped id is required — #63068 used the forwarded `SessionContext.sessionId`.)* +- **`ConnectorCapability`** (edit): add `SUPPORTS_USER_SESSION` (javadoc: gates FE injection of the per-user delegated credential; declared by iceberg-REST connectors configured `session=user`). + +### 7.2 FE bridge — `fe-core` +- **`ConnectorSessionBuilder.from(ConnectContext)`** (edit): if the target connector declares `SUPPORTS_USER_SESSION`, read `ctx.getSessionContext().getDelegatedCredential()`, map fe-core `DelegatedCredential` → `ConnectorDelegatedCredential`, and set it (plus the `SessionContext.getSessionId()`) on the built `ConnectorSession`. One place; covers all ~25 `buildConnectorSession()` call sites. (Capability check needs the connector/capabilities at build time — `PluginDrivenExternalCatalog` has the `Connector`; thread the capability set or a boolean into the builder.) +- **`ExternalCatalog.shouldBypassTableNameCache(SessionContext)`** (re-add, default false) + **`ExternalDatabase`** live-path rerouting (`getTableNamesWithLock`/`getTableNullable`/`isTableExist` → no-cache when bypassing; thread `updateTableNameLookup=false`). `PluginDrivenExternalCatalog` overrides `shouldBypassTableNameCache` to `capabilities.contains(SUPPORTS_USER_SESSION) && ctx.hasDelegatedCredential()`. Database-level bypass (the REST-catalog `getDbNames`/`getDbNullable` live paths, re-appending `information_schema`+`mysql`) is iceberg-REST-specific; in the SPI world it belongs on the plugin-driven catalog when the connector is session-aware — **open question O2** (below). + +### 7.3 Connector consumer — `fe-connector-iceberg` +- **`IcebergConnectorProperties`** (edit): add `iceberg.rest.session = none|user` (default none), `iceberg.rest.oauth2.delegated-token-mode = access_token|token_exchange` (default access_token), optional `iceberg.rest.session-timeout`. Validation: `session=user` ⇒ `security.type=oauth2`; relax the "oauth2 requires token/credential" rule for user-session. When `session=user`, the connector reports `SUPPORTS_USER_SESSION` from `Connector.getCapabilities()`. +- **Catalog build** (edit `IcebergCatalogFactory`/`IcebergCatalogOps`): build an iceberg **`RESTSessionCatalog`** for REST flavor (not `RESTCatalog`), default-bound via `asCatalog(SessionContext.createEmpty())`, so per-request `asCatalog(ctx)` is available. +- **`IcebergDelegatedCredentialUtils`** (re-migrate): `credentialKey(ConnectorDelegatedCredential.Type)` → `OAuth2Properties.{TOKEN, ID_TOKEN_TYPE, JWT_TOKEN_TYPE, SAML2_TOKEN_TYPE}`. +- **`IcebergSessionCatalogAdapter`** (re-migrate): holds plain `Catalog` + `Optional` + token mode. `catalog(session)` / `delegatedCatalog(session)` (throws without cred) / `delegatedViewCatalog(session)`; `toIcebergSessionContext(ConnectorDelegatedCredential, sessionId, mode)` → `new SessionCatalog.SessionContext(sessionId, null, credentials, ImmutableMap.of(), /*wrappedIdentity*/ user?)`. Credentials map = `access_token`→`{TOKEN:token}`, else `{credentialKey(type):token}`. +- **Session-aware catalog ops** (edit `CatalogBackedIcebergCatalogOps` or a session-aware subclass): each op (`loadTable`/`listTables`/`tableExists`/view ops/DDL) chooses `adapter.catalog(session)` vs the shared `catalog` based on `session.getDelegatedCredential().isPresent()` (the connector-side analog of `useSessionCatalog`). **Fail-closed:** if the connector is `session=user` but the session has no credential → throw (parity with #63068's `IcebergUserSessionCatalog.useSessionCatalog`). +- **Read-path** (`IcebergConnectorMetadata`/scan): the credential is already on the `ConnectorSession` passed to every metadata call, so table/schema/snapshot loads route through the adapter automatically; the FE-side cache bypass (7.2) ensures they aren't served from the shared cache. + +### 7.4 Data-flow (end to end, new architecture) +``` +login: MySQL token → DelegatedCredential → ConnectContext.sessionContext [RETAINED] +forward: FEOpExecutor → thrift 1004-1007 → ConnectProcessor.restore (sessionId kept) [RETAINED] +query: PluginDrivenExternalCatalog.buildConnectorSession() + → ConnectorSessionBuilder.from(ctx): if SUPPORTS_USER_SESSION, copy cred → ConnectorSession [NEW] + connector op(session): + session.getDelegatedCredential().isPresent() + ? adapter.delegatedCatalog(session) → RESTSessionCatalog.asCatalog(toIcebergSessionContext(...)) + : shared catalog [NEW] + FE cache: shouldBypassTableNameCache(ctx)=true → live, no shared-cache read/write [RE-ADD] +``` + +--- + +## 8. Edge cases +- **`session=user`, no credential** (e.g. password login to a user-session catalog) → **throw** fail-closed (never borrow a shared identity). Matches #63068 + its `IcebergMetadataOpTest`. +- **FE forward** — sessionId must be preserved across observer→master (retained thrift path) so the iceberg AuthSession key is stable; verify the SPI `getSessionId()` reflects the forwarded id, not a fresh UUID on the master. +- **Expired credential** — Doris does not reject non-iceberg SQL on datasource-token expiry (#63068's `ConnectProcessorDelegatedCredentialTest`); iceberg calls will fail at the REST server. Keep that behavior; surface a clear error. +- **Background/async threads** (metadata preload, auto-analyze, refresh) — `ConnectContext.get()` may be null → no credential → for a `session=user` catalog these must either be skipped or fail-closed, not silently use a shared identity. **Decide per background task** (open question O3). +- **View catalog** — REST `asCatalog()` is not itself a `ViewCatalog`; the default view catalog is `restSessionCatalog.asViewCatalog(createEmpty())`, per-user via `asViewCatalog(ctx)` (parity with #63068 `resolveDefaultViewCatalog`). +- **Nested namespaces** — gated by `isNestedNamespaceEnabled()` in #63068; preserve. +- **Cache correctness** — never populate the shared db/table/view caches from a per-user response (leakage). Assert via the re-migrated `ExternalDatabaseSessionContextTest`. + +## 9. Testing plan +Re-migrate the 8 #63068 test classes, retargeted: +- **Connector (new location):** `IcebergSessionCatalogAdapterTest` (credential-key mapping per mode; `delegatedCatalog` throws without cred; plain path without cred), plus connector-level "session=user + no cred throws" and "with cred routes to session catalog" (was `IcebergMetadataOpTest`), and read-path "view/table load bypasses shared cache" (was `IcebergUtilsTest`, `Mockito.verify(cache, never())`). +- **Retained base (should largely pass as-is; add if missing):** `DelegatedCredentialTest`, `ConnectProcessorDelegatedCredentialTest`, `FEOpExecutorDelegatedCredentialTest` — confirm they exist/pass on the current branch (they map to retained code; **task 0** verifies this). +- **Config:** `IcebergRestPropertiesTest`-equivalent in the connector property module (session=user⇒oauth2; token modes; no static-cred leakage into the shared catalog). +- **Cache bypass:** `ExternalDatabaseSessionContextTest`-equivalent (two tokens → two table sets; shared cache not populated; `lower_case_*` mapping). +- **Build/verify:** `mvn package -pl :fe-connector-iceberg,:fe-connector-paimon -am` (cache off) + relevant fe-core module tests; ideally a docker regression against a REST catalog that supports per-user sessions (Polaris/Lakekeeper) if available. + +## 10. Rollout, risks, alternatives +- **Rollout:** feature is opt-in (`iceberg.rest.session=user`, default `none`) → zero impact on existing catalogs. Ship behind the config; document. +- **Risk — cross-user cache leakage:** the highest-severity concern; mitigated by D5 bypass + `ExternalDatabaseSessionContextTest`. A review gate on the cache paths is warranted. +- **Risk — credential in memory/logs:** keep the token `SecuritySensitive`; never edit-log/persist (retained base already treats `SessionContext` as connection-scoped, non-persisted). Heed Trino's CVE-2026-34214 (creds leaked via query-info surfaces) — audit any `SHOW`/profile/`information_schema` surface that could serialize the credential. +- **Risk — SPI surface creep:** adding a credential accessor to `ConnectorSession` is universal; keep it a neutral, minimal DTO; only iceberg reads it. +- **Alternative considered — thread `SessionContext` through connector methods** (closer to #63068): rejected (D2) — pollutes the whole SPI, non-Trino, and the single-funnel injection is cleaner. +- **Alternative — config-only opt-in (pure Trino, no capability):** viable; rejected by default for least-privilege (D1), but a 1-line change if you prefer. + +## 11. Open questions (need your call) +- **O1 (D1):** capability flag `SUPPORTS_USER_SESSION` (recommended) vs pure-Trino config-only? +- **O2:** database-level cache bypass (`getDbNames`/`getDbNullable` live paths) — #63068 put it on `IcebergRestExternalCatalog`. On the SPI, does it live on `PluginDrivenExternalCatalog` (generic, gated by capability) or an iceberg-specific catalog subclass? Leaning generic-gated. +- **O3:** background/async tasks (preload/auto-analyze/refresh) under `session=user` — skip vs fail-closed? (They have no user credential.) +- **O4:** SPI `getSessionId()` — reuse `getQueryId()` or add a session-scoped id mirroring the forwarded `SessionContext.sessionId`? (Affects iceberg AuthSession cache key stability across a session's queries.) + +--- + +## 12. Ordered TODO (implementation plan — after approval) +Maps to the memory's 6-step plan, retargeted to the SPI + decisions above. + +0. **Verify retained base** on this branch: confirm MySQL-auth capture + `DelegatedCredential`/`SessionContext` + FE-forward (thrift 1004-1007) + `ConnectProcessor`/`FEOpExecutor` compile & their tests pass. (Establishes the foundation is intact.) +1. **SPI (fe-connector-api):** add `ConnectorDelegatedCredential` DTO; `ConnectorSession.getDelegatedCredential()` (+ `getSessionId()` if needed); `ConnectorCapability.SUPPORTS_USER_SESSION`. (memory step 1) +2. **FE inject (fe-core):** `ConnectorSessionBuilder.from(ctx)` copies the credential when the connector declares the capability; unit-test the injection + the no-capability skip. (memory step 2) +3. **Cache bypass (fe-core):** re-add `ExternalCatalog.shouldBypassTableNameCache` + `ExternalDatabase` live paths; `PluginDrivenExternalCatalog` override gated by capability+credential. Re-migrate `ExternalDatabaseSessionContextTest`. (part of step 5) +4. **Connector props (fe-connector-iceberg):** `iceberg.rest.session` + `delegated-token-mode` + validation; declare `SUPPORTS_USER_SESSION` when `session=user`; re-migrate `IcebergRestPropertiesTest`-equiv. (memory step 3) +5. **Connector session catalog (fe-connector-iceberg):** build `RESTSessionCatalog`; re-migrate `IcebergDelegatedCredentialUtils` + `IcebergSessionCatalogAdapter`; make catalog-ops session-aware (fail-closed); re-migrate `IcebergSessionCatalogAdapterTest`. (memory steps 4+5) +6. **Read/DDL routing (fe-connector-iceberg):** ensure `IcebergConnectorMetadata` metadata/scan/DDL ops honor the per-request credential via the adapter; re-migrate the `IcebergMetadataOpTest`/`IcebergUtilsTest`-equiv (fail-closed + cache-`never()`). (memory step 5) +7. **Verify:** full connector-suite build (cache off) + fe-core module tests; docker regression vs a per-user REST catalog if available.

Need to confirm the credential survives to the thread that calls `buildConnectorSession`. + +### A4. `listTableNamesFromRemote(SessionContext ctx, ...)` / `tableExist(SessionContext ctx, ...)` (fe-core:278/299) +Both **receive** a fe-core `SessionContext ctx` but call `buildConnectorSession()` **without** it → `ctx` discarded (memory's "DISCARD SessionContext").

Connector iceberg catalog construction — `CatalogBackedIcebergCatalogOps` (fe-connector-iceberg) +- Wraps a **single shared** `org.apache.iceberg.catalog.Catalog catalog` (`private final Catalog catalog`, :199); all ops delegate to it (`catalog.loadTable/listTables/tableExists/...`). +- Has a `restFlavor` boolean ctor arg (:210) → the connector already knows REST vs non-REST. +- **grep confirms: NO reference to `RESTSessionCatalog` / `SessionContext` / `DelegatedCredential` / `getExtraCredentials` in fe-connector-iceberg main.** The entire per-user session mechanism is absent here → **must be re-migrated** (the IcebergUserSessionCatalog / IcebergSessionCatalogAdapter role). +- → **Consumer point**: a session-aware REST catalog ops that, when `SUPPORTS_USER_SESSION` + a REST catalog + a per-request credential, builds/uses a per-user `org.apache.iceberg.rest.RESTSessionCatalog` with a `SessionCatalog.SessionContext` carrying the user's OAuth2/delegated credential, instead of the shared `catalog`. + +### A6.

The migration builds ON this — it is NOT rebuilt. +- **`ConnectContext`**: `private SessionContext sessionContext = SessionContext.empty()` + `getSessionContext()` / `setSessionContext()` (:316/:320). The per-connection credential lives here. +- **`SessionContext`** (fe-core datasource): `getSessionId()`, `getDelegatedCredential(): Optional`, `hasDelegatedCredential()`, `getDelegatedCredentialExpiresAtMillis()`, `isDelegatedCredentialExpired(now)`; factories `empty()/current()/of(cred)/of(sessionId,cred)`. +- **`DelegatedCredential`** (fe-core datasource): fields `Type type` (enum), `String token`, `Long expiresAtMillis`; `getType()/getToken()/getExpiresAtMillis()/isExpired(now)`. +- **Cross-FE forwarding intact**: `FrontendService.thrift` fields **1004-1007** (`delegated_credential_type/token/expires_at_millis/session_id`) retained; `ConnectProcessor` (:834-847) reads them off a forwarded `TMasterOpRequest` and rebuilds `context.setSessionContext(SessionContext.of(sessionId, new DelegatedCredential(...)))` on the master FE. `FEOpExecutor` sets them on the outbound request (to confirm in Part C). +- **Consequence**: on any FE thread running the query, `ConnectContext.get().getSessionContext().getDelegatedCredential()` yields the user's credential. `buildConnectorSession()` (A3) already reads `ConnectContext.get()` → the injection is a **1-line-ish** copy into the neutral SPI DTO. The thread-local caveat (A3) is covered because forwarding re-materializes the SessionContext on the executing FE. +- **Still to confirm on current branch (Part C / follow-up):** the MySQL-auth ingress (does `AuthenticatorManager`/`MysqlAuthPacketCredentialExtractor` still set the credential onto ConnectContext?), and whether `ExternalCatalog.shouldBypassTableNameCache` is retained. + +## Part B — Trino reference (delegated-credential / session SPI) *(subagent, read real Trino+Iceberg source 2026-07-10)* + +**Flow:** `X-Trino-Extra-Credential` header → `Identity.extraCredentials` (opaque `Map`, engine never interprets) → `ConnectorSession.getIdentity().getExtraCredentials()` → **per-request** `TrinoRestCatalog.convert(ConnectorSession)` → Iceberg `SessionCatalog.SessionContext(sessionId, user, credentials, properties, wrappedIdentity)` → **single shared** `RESTSessionCatalog` mints/refreshes a per-`sessionId` OAuth2 `AuthSession`. + +**The integration seam is Iceberg's, not Trino's** — `org.apache.iceberg.catalog.SessionCatalog.SessionContext` (iceberg **api** module): `SessionContext(String sessionId, String identity, Map credentials, Map properties, Object wrappedIdentity)`; getters `credentials()`, `properties()`, `wrappedIdentity()`. Doris depends on the **same** `iceberg-core RESTSessionCatalog`, so this contract is fixed for us too. + +**Two orthogonal config axes** (both catalog-level config, `IcebergRestCatalogConfig`): +- `iceberg.rest-catalog.security = NONE|OAUTH2|SIGV4|GOOGLE` → the *static, catalog-level* credential (`SecurityProperties.get()` → `{token, credential}`). +- `iceberg.rest-catalog.session = NONE|USER` (`SessionType`, default NONE) → per-user projection: + - **NONE**: `sessionId=randomUUID`, `user=null`, `credentials=` static catalog creds. One shared principal at the REST server. + - **USER**: deterministic `sessionId = user-queryId-source`, real `user`, `credentials =` the user's `extraCredentials` **plus a freshly Trino-SIGNED subject JWT** (`OAuth2Properties.JWT_TOKEN_TYPE`, `sub=`). Lets the REST server (Polaris/Lakekeeper/Unity) enforce per-user authz + vend per-user scoped storage creds. `wrappedIdentity` still carries the real identity for per-user FileIO. + +**Opt-in = per-connector CONFIG, NOT an SPI capability.** Trino has **no** "supports per-user session" capability flag; the SPI hands *every* connector `getExtraCredentials()` universally, and the iceberg connector alone decides via its `SessionType` enum. → **Design divergence to surface**: the memory's 6-step plan (from #63068) adds `ConnectorCapability.SUPPORTS_USER_SESSION`. Reconcile — see design-decision D1. + +**Cache tension (load-bearing):** the `RESTSessionCatalog` object is a **single shared instance** (`create()` memoizes it; per-user isolation is 100% at the per-request `SessionContext` layer — never cache a catalog-per-user). But per-user vended credentials mean the REST *server* enforces per-user authz/vending; a **shared FE metadata/name cache would leak one user's authorized/vended view to another** → for `session=user` the FE cache must be **bypassed or user-partitioned** (this is exactly what #63068's `shouldBypassTableNameCache` is for). Also: `sessionId` embeds `queryId` → the iceberg AuthSession cache is effectively **per-query** (token-exchange volume note). + +**Doris-specific gap:** MySQL/JDBC wire protocol has no `X-Trino-Extra-Credential` equivalent → Doris needs its own channel to get the user's OIDC credential onto the session. #63068 solved this via the MySQL auth path (see Part C). + +## Part C — #63068 as-built (`e545f1ad08a`) *(subagent, read the commit 2026-07-10; full note in agent transcript)* + +**Flow (pre-P6):** MySQL login → `MysqlAuthPacketCredentialExtractor` → `Authenticator` returns `AuthenticationResult` w/ expiry → `AuthenticatorManager.attachDelegatedCredential` builds `DelegatedCredential(type,token,expiry)` → `context.setSessionContext(SessionContext.of(cred))`. Observer→master forward: `FEOpExecutor.buildStmtForwardParams` writes thrift 1004-1007 → `ConnectProcessor.restoreForwardedSessionContext` rebuilds `SessionContext.of(sessionId,cred)` (**sessionId preserved**). Metadata ops read `SessionContext.current()`. + +**The 3 deleted iceberg-consumer classes (re-migrate):** +- **`IcebergUserSessionCatalog`** (capability interface, ~60 LOC): `useSessionCatalog(SessionContext): boolean` — the single decision, **THROWS if `session=user` but no credential** (a per-user catalog has no shared identity to borrow); `getRestSessionCatalog()`, `getDelegatedTokenMode()`, `isViewEnabled()`, `isNestedNamespaceEnabled()`. +- **`IcebergSessionCatalogAdapter`** (Doris↔Iceberg bridge, ~150 LOC): holds plain `Catalog` + `Optional` (the injected `RESTSessionCatalog`) + `DelegatedTokenMode`. `catalog(ctx)` (plain if no cred else `sessionCatalog.asCatalog(icebergCtx)`), `delegatedCatalog(ctx)` (requires cred), `delegatedViewCatalog(ctx)`, and `static toIcebergSessionContext(ctx, mode)` → `new org.apache.iceberg.catalog.SessionCatalog.SessionContext(ctx.getSessionId(), null, credentials, ImmutableMap.of())`. +- **`IcebergDelegatedCredentialUtils`** (~43 LOC): `credentialKey(DelegatedCredential.Type)` → Iceberg OAuth2 key: `ACCESS_TOKEN→OAuth2Properties.TOKEN`, `ID_TOKEN→ID_TOKEN_TYPE`, `JWT→JWT_TOKEN_TYPE`, `SAML→SAML2_TOKEN_TYPE`. + +**Credential map (`toIcebergCredentials`):** `access_token` mode → `{TOKEN: token}` (bearer, verbatim); `token_exchange` mode → `{credentialKey(type): token}` (server does RFC-8693 exchange). NOTE: #63068 passes the token verbatim; it does **NOT** mint a signed subject JWT the way Trino's `session=user` does (Trino adds `sub=`). If the REST server must trust a *Doris-asserted* identity rather than the client-supplied token, that signing step is a future gap (Trino parity) — for OIDC pass-through it isn't needed. + +**Config (`IcebergRestProperties`):** `iceberg.rest.session = none|user` (default none); `iceberg.rest.oauth2.delegated-token-mode = access_token|token_exchange` (default access_token); `iceberg.rest.session-timeout` → `CatalogProperties.AUTH_SESSION_TIMEOUT_MS`. **`session=user` requires `security.type=oauth2`.** Built around iceberg **`RESTSessionCatalog`** (not `RESTCatalog`) so `asCatalog(ctx)`/`asViewCatalog(ctx)` work; default catalog = `restSessionCatalog.asCatalog(SessionContext.createEmpty())`. The OAuth2 "requires credential or token" validation rule is relaxed for a user-session catalog (it has no static bootstrap cred). + +**Session routing (`IcebergMetadataOps`, pre-P6):** fields captured at construction (`userSessionCatalog`, `sessionCatalogAdapter`, `defaultViewCatalog`); private routers `catalog(ctx)`/`namespaces(ctx)`/`viewCatalog(ctx)` switch on `useSessionCatalog(ctx)`; every op got a `SessionContext` overload (read=`empty()`, DDL=`current()`). `IcebergUtils` read-path (`getIcebergTable/View/getSchemaCacheValue/...`) guards on `useSessionCatalog(dorisTable)` and **bypasses the shared meta cache** (`loadIcebergTableWithSession` loads live via `ops.loadTable(ctx,...)`). + +**Cache bypass:** `ExternalCatalog.shouldBypassTableNameCache(SessionContext): boolean` (default false) — overridden by the REST catalog to `useSessionCatalog(ctx)` ("bypass cache" ≡ "use per-user session"). Rationale: the shared db/table/view caches are keyed catalog+name, NOT user; under `session=user` the REST server returns per-user metadata → a shared cache would leak user A's visible set to user B. `ExternalDatabase` (+86) reroutes `getTableNamesWithLock/getTableNullable/isTableExist` to live, no-cache paths (threads `updateTableNameLookup=false`); the REST catalog mirrors this for **databases** (`getDbNames/getDbNullable` → live, re-append `information_schema`+`mysql`). + +**Generic (retained ✅) vs iceberg-consumer (re-migrate ❌):** ALL of SessionContext/DelegatedCredential/ConnectContext/ConnectProcessor/FEOpExecutor/thrift-1004-1007/mysql-auth = GENERIC, **retained & functional** (Part A7). Re-migration surface = the 3 deleted classes + session routing (`IcebergMetadataOps`/`IcebergUtils`/`IcebergRestExternalCatalog`) + config (`IcebergRestProperties`) + the two generic-but-iceberg-driven cache hooks (`ExternalCatalog.shouldBypassTableNameCache`, `ExternalDatabase` bypass). + +**⚠️ RE-TARGETING (the core adaptation):** #63068 lived in the **fe-core** iceberg tree. P6/#64688 **moved iceberg into `fe/fe-connector/fe-connector-iceberg`** (`IcebergConnectorMetadata`, `CatalogBackedIcebergCatalogOps` wrapping a single shared `Catalog`; the fe-core `IcebergMetadataOps` DDL shim remains but its session routing was stripped, and `IcebergRestProperties`/`IcebergRestExternalCatalog` no longer exist in fe-core). So the re-migration must (1) drive the decision off the **`ConnectorSession` credential** (Trino-style, injected in `buildConnectorSession`) instead of `SessionContext.current()`, and (2) place the RESTSessionCatalog + adapter in the **connector**, not fe-core. The fe-core cache-bypass hooks (`ExternalCatalog`/`ExternalDatabase`) stay in fe-core but key off the SPI capability + the injected credential. + +**Tests to re-migrate (8):** `IcebergSessionCatalogAdapterTest`(8: credential-key mapping, throws-without-cred), `IcebergMetadataOpTest`(+2: enabled+no-cred throws, +cred returns true), `IcebergUtilsTest`(+2: view routes to loadView, shared cache `never()` called), `DelegatedCredentialTest`(3: expiry semantics), `ConnectProcessorDelegatedCredentialTest`(5: forward re-hydrate, missing-field throws), `FEOpExecutorDelegatedCredentialTest`(1: forward copies+preserves sessionId), `IcebergRestPropertiesTest`(+7: session=user oauth2 build, token modes, no-leak into shared catalog), `ExternalDatabaseSessionContextTest`(4: per-token table sets, no shared-cache populate, lower_case names).

`=user`. +4. **Consumer**: session-aware REST ops in fe-connector-iceberg build a per-user `RESTSessionCatalog` from `session.getDelegatedCredential()` (re-migrated IcebergUserSessionCatalog/SessionCatalogAdapter/DelegatedCredentialUtils). +5. **Routing + cache bypass**: per-user session → bypass shared table-name cache

Java 值重推 canonical string；hive 用 `String.valueOf(val)` 推错（datetime 出 ISO `T`、decimal 出保 scale/科学计数），iceberg 手写 `dorisDateTimeString()` + bool `1/0` 推对；这是 hudi/paimon/hive 一系列分区匹配 bug 的共同 SPI 根因。 + +**核实过程**（融合 investigate.code_reality + verify.recheck_notes，均按当前工作树亲验）： + +1. `ConnectorLiteral.java`（fe-connector-api/.../pushdown/ConnectorLiteral.java:33-119）确实只存 `ConnectorType type` + 裸 `Object value`；访问器只有 `getType()`(81)、`getValue()`(86)、`isNull()`(90)；`toString()` 即 `value.toString()`(100-102)。工厂 `ofDatetime/ofDate/ofDecimal`(69-79) 只塞 `LocalDateTime/LocalDate/BigDecimal`，**不带 canonical 文本**。全类无任何 typed `getStringValue()`/canonical 访问器。**结构主张成立**。 +2. `ExprToConnectorExpressionConverter.convertDateLiteral`（fe-core/.../converter/ExprToConnectorExpressionConverter.java:302-322）：DATE/DATEV2 分支存裸 `LocalDate`(314)，否则 DATETIME 存裸 `LocalDateTime`(316-320)。边界处 `DateLiteral` 本可给 canonical 文本，但被丢弃。**「边界丢 canonical」主张成立**。 +3. `IcebergPredicateConverter`（fe-connector-iceberg/.../IcebergPredicateConverter.java:310-360, 507）：Boolean→`"1"/"0"`(322)、LocalDate 分支(326)、LocalDateTime→`dorisDateTimeString`(342)、BigDecimal 分支(348)。**iceberg 手写推对，成立**。 +4. 【关键反证】`HiveConnectorMetadata.extractLiteralValue`（fe-connector-hive/.../HiveConnectorMetadata.java:2246-2270）：LocalDateTime→`hiveDateTimeString()`(2259)、BigDecimal→`stripTrailingZeros().toPlainString()`(2267)、`String.valueOf(val)`(2269) 仅作标量兜底。注释 2255-2266 逐字记录了旧 `String.valueOf` 曾把整表剪到 0 行的 bug、并说明已改为 Hive-canonical 渲染。`git log -S 'stripTrailingZeros().toPlainString()'` 仅命中 commit `3593684715f`（hive 连接器引入）。**「hive 现行错」确已过时**。 +5. `HudiConnectorMetadata.extractLiteralValue`（fe-connector-hudi/.../HudiConnectorMetadata.java:1092-1108）：仅 LocalDateTime→`hiveDateTimeString`(1105)，**无 BigDecimal 分支**，decimal 走 `String.valueOf`(1107)。`git log -S stripTrailingZeros -- fe-connector-hudi/` 零命中，证明 hive 的 decimal 修复**从未同步到 hudi**。残留成立。 +6. （verify 补查，stage-1 未做）`PaimonPredicateConverter.convertLiteralValue`（fe-connector-paimon/.../PaimonPredicateConverter.java:244-290）：把 value 转成 Paimon **原生 typed 对象**（BigDecimal→`Decimal.fromBigDecimal`:266-268、LocalDateTime→Paimon Timestamp:286-287），再构造原生 Predicate，**不走 canonical 字符串比较路径**。 + +**背景**：SPI 的 `ConnectorLiteral` 是「裸 Object + toString」，没有 typed 访问器。canonical 文本在 fe-core 边界（`convertDateLiteral`）本可从 `DateLiteral` 拿到却被丢弃，只存 `LocalDateTime/LocalDate`。后果是每个连接器必须各自从 Java 值重建 Hive/Doris canonical 字符串，形成 divergent fill：iceberg 一套（推对）、hive 一套、hudi 一套、paimon 又用原生 typed 对象一套。「缺 typed 访问器 → N 份重复重建 → 易分叉」的设计缺口**客观存在**，报告对它的方向性观察准确且有价值。 + +**为何降为 PARTIAL（主张过时之处）**：报告把 hive 明确标为「现行错、根因」，称 `extractLiteralValue` 用 `String.valueOf` 推错。但当前工作树中该方法已修（见核实过程 4）——LocalDateTime 走 `hiveDateTimeString()` 输出 `2024-01-01 10:00:00`（空格分隔、补秒）而非 ISO `2024-01-01T10:00`；BigDecimal 走 `stripTrailingZeros().toPlainString()` 输出 `1`（去尾零、避科学计数）而非保 scale 的 `1.0000`；`String.valueOf` 仅对 Boolean/Int/Long 兜底，而这些类型 `String.valueOf` 结果恰是 Hive canonical（`true/false`、纯整数），不产生剪 0 行。因此报告基于「几天前代码」所述的 hive 活跃 bug 在当前代码已不存在。故非 CONFIRMED，也非 STALE_FIXED（架构缺口与 hudi 残留仍在）。 + +**影响**（基于当前代码的真实可复现面）： + +- **hive：无**。datetime/decimal 分区列做 WHERE 等值/IN 剪枝已正确。例：`SELECT * FROM hive_tbl WHERE dt_part = '2024-01-01 10:00:00'` 或 `dec_part = 1.0`，当前会命中而非剪到 0 行。 +- **hudi：decimal 分区列仍有潜在剪枝失配**。具体示例：hudi 表以 `decimal(8,4)` 列 `d` 分区、存储分区值字符串为 `"1"`，查询 `WHERE d = 1` —— Nereids 传入 BigDecimal `1.0000`，`extractLiteralValue` 走 `String.valueOf`(1107) 得 `"1.0000"`，与存储 `"1"` 字符串不等 → `matchesPredicates` 失配、该分区被**误剪**（本应命中的行返回空）。datetime 分区 hudi 已修（1105），不受影响。此残留的运行时可复现性依赖「hudi 用 decimal 列分区 + matchesPredicates 走字符串等值比较」前置，故措辞为「潜在失配」而非确证运行时 bug。 +- **DATE(LocalDate) 路径**：hive/hudi 均走 `String.valueOf`→`2024-01-01`（ISO 即 Hive canonical date），**无 bug**。 +- **Boolean 路径**：hive/hudi 的 `String.valueOf` 对 Boolean 产出 `true`/`false`，恰是 Hive 布尔分区 canonical，**无 bug**。iceberg 需 `1`/`0` 是其对接 `BoolLiteral.getStringValue()` 语义（IcebergPredicateConverter:321），两者要求不同、各自都对。故原报告笼统称「Boolean 出 true/false 不等于 canonical」在 hive 语境下不成立。 +- **paimon 校准**：paimon 不走 canonical-string 路径（原生 typed 对象），不存在 string-compare 失配。原报告把 paimon 归入「同一 canonical-string 分区 bug」对 paimon **不准确**；但 paimon 恰是第 4 份各自为政的字面量重实现，反而更强化「缺 typed SPI 访问器 → N 份分叉」的架构论点。建议把 paimon 从「受害连接器」改列为「另一种分叉规避方式」。 + +**修复方案**（超出本条主张范围，二选一）： + +1. 若只消除残留：把 hive 的 BigDecimal(`stripTrailingZeros().toPlainString()`) 分支镜像进 `HudiConnectorMetadata.extractLiteralValue`（HudiConnectorMetadata.java:1107 之前），与其已镜像的 LocalDateTime 分支一致。小步、低风险。 +2. 若根治架构分叉（工作量大、涉铁律 A「fe-core 只出不进」）：**不**在 fe-core 加 helper，而是在 `ConnectorLiteral` 上增设各连接器可复用的 canonical 渲染入口，或在 `ExprToConnectorExpressionConverter` 边界透传 `DateLiteral` 的 canonical 文本，消除三处（iceberg/hive/hudi）重复重建。此项应交 review 定夺，不宜在核实中擅动。 + +--- + +## #23 ConnectorDomain 无 CHAR padding + +**核实结论**：**CONFIRMED**（置信度 medium）。两阶段一致；verify 完整复读 `ConnectorRange`/`ConnectorFilterConstraint` 并确认死代码结论，`corrections` 为空。字面主张成立，但因目标类是死代码，**实际严重度低于报告标注的「潜伏」**。 + +**原报告主张**：`ConnectorDomain` 用 `Comparable` 建模谓词值，但没有 CHAR(n) 定宽 padding 语义；CHAR(n) 定宽比较（尾部空格填充）无法忠实表达。 + +**核实过程**（融合 investigate.code_reality + verify.recheck_notes）： + +1. `ConnectorDomain`（fe-connector-api/.../pushdown/ConnectorDomain.java:33-116）持有 `ConnectorType type` + `List ranges` + `boolean nullsAllowed`；值在 `ConnectorRange`（ConnectorRange.java:34,37）中以 `Comparable low/high` 存储。`equal()`(54-57) 裸塞值不归一化，`isSingleValue()`(109-112) 用 `low.equals(high)` 精确比较，`equals()`(125-138) 精确比较。**全类无任何按类型/长度做尾空格 padding 或截断的逻辑**——`type` 仅参与 equals/hashCode/toString，不驱动 CHAR(n) 定宽比较。**字面主张成立**。 +2. 整条 `ConnectorDomain/ConnectorRange` 抽象在当前工作树是**死代码**：grep `new ConnectorDomain|ConnectorDomain.(all|none|singleValue|onlyNull)|getColumnDomains|columnDomains`，排除 `ConnectorDomain.java`/`ConnectorFilterConstraint.java` 后**零命中**——从不被构造、从不被读取。 +3. 唯一生产侧构造 `ConnectorFilterConstraint` 的点 `PluginDrivenScanNode.java:1941`（经 `buildFilterConstraint`:1939）传 `Collections.emptyMap()` 给 columnDomains，故 domain map 恒空。 +4. 三个消费者 `HiveConnectorMetadata.applyFilter`（HiveConnectorMetadata.java:1103,1132）、`HudiConnectorMetadata`（:264,313）、`TrinoConnectorDorisMetadata`（:260）**全部只读 `constraint.getExpression()`**（表达式树，走 ConnectorLiteral 路径），无一调用 `getColumnDomains()`。 +5. `getColumnDomains|.columnDomains` 全仓仅命中 `ConnectorFilterConstraint.java` 自身（:32 javadoc、:47 构造赋值、:67 getter），无外部消费者；单参构造器亦默认 emptyMap。`ConnectorDomain` 自 `5c325655b8b`（初始 SPI 框架引入）后未再改动，自始未接线。 + +**背景**：`ConnectorDomain`+`ConnectorRange` 是 SPI 里一套「按列的取值域摘要」，javadoc 自称「Used for fast partition pruning」。它把谓词边界值以 `Comparable` 存储，只附带 `ConnectorType`，不携带 CHAR(n) 定宽长度，也无尾部空格填充逻辑。就类的形状而言，主张全部属实。 + +**影响**（当前对任何查询**零影响**；下例仅在假设未来有人接线 domain 剪枝时才成立）：设 hive 外表 `t(c CHAR(5))`，某行 `c` 逻辑值为 `'AB'`（CHAR 语义下等价于 `'AB '` 三个尾空格）。查询 `WHERE c = 'AB'`。若将来有人把这条谓词摘要成 `ConnectorDomain.singleValue(CHAR(5), "AB")`，`ConnectorRange.equal` 会用裸串 `"AB"` 做 `.equals` 比较（ConnectorRange.java:111,136），既不会把探针 padding 到 `'AB '`，也无从判断存储侧是 padding 还是 trim 的表示，可能与 CHAR 定宽语义下应命中的行错配。**但这条链路今天不存在**，且同样的 CHAR 填充问题在真正生效的表达式路径（ConnectorLiteral，`ExprToConnectorExpressionConverter.java:300-301` 把 `StringLiteral.getValue()` 原样塞入）里本就同样存在，属独立议题，与 `ConnectorDomain` 无关。此外该缺口对全部类型一视同仁地不生效，并非 CHAR 特有。 + +**修复方案**（优先级低，二选一）： + +1. **最省**：既然 `ConnectorDomain/ConnectorRange` 至今零使用，直接删除这套死抽象（连同 `ConnectorFilterConstraint.columnDomains` 字段与 `getColumnDomains()`），消除误导性 javadoc，避免后人误接线时踩 CHAR/DECIMAL 归一化坑。 +2. 若保留以备将来 domain 剪枝：在真正被填充的构造侧引入类型感知归一化（CHAR(n) 边界值统一 padding 到定宽再比较，或 `ConnectorType` 携带长度并在比较处 padding），但应等该路径真被启用时再做，现在做属投机（违反「不写投机代码」）。 + +综上：主张字面成立（CONFIRMED），但目标类是死代码，实际严重度低于「潜伏」，当前无需修，建议记为「删除死抽象」候选而非缺陷修复。 + +--- + +## 本类别小结 + +- **真问题（残留）**：#1 揭示的架构缺口——`ConnectorLiteral` 无 typed canonical 访问器、边界丢弃 `DateLiteral` canonical 文本——真实存在，且导致 hudi 的 **decimal 分区谓词** 仍走 `String.valueOf` 而与 hive 已修分支不对齐（HudiConnectorMetadata.java:1107）。这是本类别唯一有运行时可复现面的残留（潜在剪枝失配）。 +- **伪/已修**：#1 报告主张的核心——「hive 现行错、String.valueOf 推错」——已在 commit `3593684715f` 修复，与当前工作树不符（过时）；paimon 被误归为同类 canonical-string 受害者（实为原生 typed 路径，另一种规避方式）。#23 字面成立但目标是彻底死代码（columnDomains 恒空、零消费者），当前零影响。 +- **共性根因**：SPI 谓词/字面量层**缺少 typed、canonical-aware 的统一表示**。`ConnectorLiteral` 只携裸 Java 值 + `ConnectorType`，不带 canonical 文本；`ConnectorDomain` 只携 `Comparable` + 类型，不带 CHAR 长度/padding。结果是「每个连接器各自从 Java 值重建 canonical string」（#1，4 份分叉）或「无法忠实表达定宽语义」（#23）。修复难以在各连接器间对齐（hive 修了、hudi 没跟）正是这一缺口的直接症状。 +- **与其他类别关联**：#1 的 canonical-string 分区匹配问题，与「分区剪枝 / matchesPredicates」类别的连接器侧失配直接相连（谓词字面量是剪枝的输入）；#23 的 CHAR padding 缺口在真正生效的 `ConnectorLiteral`/表达式路径上同样存在，应并入「字符串/CHAR 语义忠实度」议题统一考量，而非孤立看 `ConnectorDomain` 死抽象。 diff --git a/plan-doc/catalog-spi-mismatch/analysis-B-schema-column-identity.md

SPI 数据模型固定为整型：`ConnectorPartitionField.java:38` `private final List transformArgs;`；构造器（`:40-47`）、getter（`:57-59`）、`equals/hashCode/toString` 全部围绕 `List`；类 javadoc（`:31-32`）明写 "carries numeric parameters"。 +2. ALTER 路径更严：`PartitionFieldChange.java:44` `private final Integer transformArg;`（**单个整数**，非 list），旧值字段同样是 `Integer`；javadoc（`:36`）说明只承载 bucket/truncate 宽度。 +3. 生产者（fe-core → SPI 转换）`CreateTableInfoToConnectorRequestConverter.java:178-199`（实际路径为 `fe/fe-core/src/main/java/org/apache/doris/connector/ddl/CreateTableInfoToConnectorRequestConverter.java`，非 JSON 提示的 `datasource/connector/converter/`）：`List args`（`:182`）；收集分支——`IntegerLikeLiteral` 走 `getIntValue()`（`:186-187`）；其它 `Literal` **仅当** `getValue() instanceof Number` 才 `intValue()` 入列（`:190-191`）。非 Number 字面量（如 `StringLiteral`，本身是 Literal 但 value 是 String）进入 `:188` 的 else-if 后，内层 `:190` 判 false→无 else→**什么都不做→静默丢弃**。`convertFields`（`:161-176`）对 `UnboundSlot` 走 identity 空 args，未知表达式静默丢。 +4. 消费者：`IcebergSchemaBuilder` 中只有 `bucket`（`:176`）与 `truncate`（`:197`）用到 args，经 `intArg`（`:206-212`）取 `args.get(0)` 当 int；`identity/year/month/day/hour` 均无参；未知 transform 直接抛异常（`:200`）。全连接器 grep `getTransformArgs/getTransformArg`：唯一消费者是 Iceberg——`IcebergSchemaBuilder`（CREATE）与 `IcebergCatalogOps.java:585/603/621`（ALTER，经 `getTransform(name, col, Integer arg)`）；Paimon/Hive 零消费，佐证其分区列 identity-only。 + +**背景**：SPI 用 `ConnectorPartitionField.transformArgs`（`List`）承载分区 transform 参数，ALTER 场景（`PartitionFieldChange.transformArg`）甚至只是单个 `Integer`。converter 从 Nereids `UnboundFunction` 抽参时只把整型字面量塞进 args，凡非 Number 的字面量被静默丢弃。 + +**影响（真实但纯潜伏，当前无可复现错误案例）**： + +遍历当前支持连接器的全部分区 transform，没有任何一个接受非整型参数： +- Iceberg 分区 transform 全集 = `identity / bucket[N] / truncate[W] / year / month / day / hour / void`，唯二带参的 `bucket`、`truncate` 都是整型宽度，`IcebergSchemaBuilder.java:176/197` 正是按 int 消费，`intArg`（`:206`）取 `args.get(0)`。 +- Paimon/Hive 的分区列均为 identity，无参。 + +因此对今天所有真实 DDL（如 `PARTITIONED BY (bucket(16, id), truncate(4, name), day(ts))`），`List` 完全够用，不会产生错误结果。真正暴露面只在未来引入「带非整型参数的分区 transform」时才出现，届时具体错误路径有两类： + +- **非整型（字符串）参数被静默丢弃**：假设未来支持 `truncate('prefix', col)` 这类字符串参数 transform，输入 `PARTITIONED BY (truncate('prefix', name))`→converter 在 `:190` 判 `'prefix'` 非 Number→丢弃该参数→连接器侧拿到空 args→`IcebergSchemaBuilder.java:207-210` 抛 "requires an integer argument"，或建出参数丢失的错误分区规格。 +- **小数参数被无声截断为 int**（verify 比 stage-1 更进一步发现的盲区）：即便是数值型但非整数的参数（`DecimalLiteral/DoubleLiteral`）也不会被丢弃，而是经 `:191` `((Number) v).intValue()` 被静默截断——例如 `truncate(4.9, col)`→args 变成 `4`。故上限不止「非整型丢失」，还含「小数参数被无声截断」。当前 Iceberg/Paimon/Hive 无小数参数 transform，同样不触发，仍属潜伏。 + +（verify 另一处措辞细化：非整型字面量的丢弃点精确说是 `:190` 内层 `if (v instanceof Number)` 判 false 后无 else，它确实进入了 `:188` 的 else-if 分支、只是分支内不处理；效果等同静默丢弃，不影响 stage-1 结论。） + +**修复方案**： + +现状无需改动（无活跃缺陷，遵循 YAGNI，不提前抽象）。若将来确有非整型参数 transform 需求，最小改动清单： +1. 把 `transformArgs` 从 `List` 放宽为 `List`（或 `List/List`）。 +2. 放宽 `CreateTableInfoToConnectorRequestConverter.convertTransformField` 的字面量收集（`:188-192`），不再静默丢弃非 Number、不再无声截断小数。 +3. `PartitionFieldChange.transformArg`（`:44`）一并放宽。 +4. 各连接器 SchemaBuilder 的 `intArg` 保持向后兼容（整型 transform 仍按 int 解析）。 +5. **（verify 补，stage-1 遗漏）** Iceberg ALTER 三个消费入口 `IcebergCatalogOps.java:585/603/621`（经 `getTransform` 消费 `Integer transformArg`）也要同步放宽——stage-1 修复方案仅提了 SchemaBuilder 的 CREATE 侧。 + +--- + +## 本类别小结 + +- **真伪分布**：本类别四条发现，无一是凭空伪报——但性质各异。#4 是「曾真、现已修」（STALE_FIXED）：报告基于几天前快照，缺陷真实且严重（🔴 丢行），但当前工作树已由 #65473 完整修复并加单测，无需再动。#13 是「机械事实真、定性高估」（PARTIAL）：`initialValues` 对 LIST/RANGE 显式值恒空未 lower 属实，但这是注释显式记录的有意分层、零消费者、需要的信息经 `hasExplicitPartitionValues` 无损保留并 fail-loud，属 vestigial 未接线槽位而非活跃缺陷，🟠 被高估。#14 是「技术事实真、休眠定性错」（PARTIAL）：paimon 的 raw spec 无类型不一致属实，但同一缺陷经 `getNameToPartitionValues` 在 `partition_values()` TVF 上活跃产错（DATE epoch-day 报错/错值、null 显 `__DEFAULT_PARTITION__` 而非 SQL NULL），并非休眠，严重度被低估。#20 是「真、但纯潜伏」（CONFIRMED）：类型层面的表达力上限确实存在，但当前三个连接器（Iceberg/Paimon/Hive）的所有分区 transform 均无非整型/小数参数，今天没有任何可复现的错误结果。 +- **共性根因**：四条都源于「SPI 数据模型对分区语义做了窄化/不完整假设」。#4 假设 HMS 返回的分区名与谓词字面量在**同一 escape 层**（忽略 HMS 的 Hive-escape）；#13 抽象槽位只接线一半（标志位接了、显式值 lowering 留待后续）；#14 用 raw spec 而非 rendered 值做按名索引（忽略 DATE/null 的渲染口径）；#20 假设 transform 参数恒为整型（忽略未来非整型/小数参数）。#4 已随迁移成熟被修正；#14 有活跃产错点需真修（改 `getNameToPartitionValues` 用 rendered 值）；#13、#20 则因当前需求边界内够用而保留为已知（vestigial / 潜伏上限）。 +- **与其他类别关联**：#4 报告自身点名「与 hudi P3 同族」——同属「分区值/名的 escape/unescape 一致性」问题族，应与 hudi 侧 P3 发现交叉核对是否同样已修；#14 的 raw-vs-rendered 分歧（DATE epoch-day、`__DEFAULT_PARTITION__` 未归一）与该族同源，是「分区值渲染口径一致性」的姊妹问题。#13、#20 属 DDL/schema 建模的表达力边界（「全部DDL」类），与其他 S 级潜伏项同属「先落地够用、留待需求驱动放宽」的一类，不建议提前抽象；其中 #13 的 vestigial 槽位可择机删除以消除 SPI 抽象错配。 diff --git

`currentResidual.residualFor(dataFile.partition()).equals(Expressions.alwaysFalse())` 命中即 skip 该文件 —— 这是 residual 的唯一用途(FE 剪枝)。 +2. 生成 BE range 的 `buildRange`(`IcebergScanPlanProvider.java:1241-1278`)完全不读 `task.residual()`,只写 path/start/length/fileFormat/formatVersion/partitionSpecId/partitionDataJson/partitionValues/deleteFiles 等,无任何 per-range

收到的过滤是 scan-node 级的整套下压 conjuncts(对每个文件逐行 apply),而非 iceberg 每文件裁剪后的 residual。 + +**背景**:iceberg 规划时,SDK 会为每个 `FileScanTask` 算一个 residual(残差谓词):把整体过滤按该文件的分区值绑定后,剩下 BE 仍需逐行验证的部分。理论上,若某文件的分区值已完全满足某分区谓词,该谓词可从该文件的 residual 中剔除,BE 无需对这些行重复验证。Doris(连接器与 legacy 一致)不利用这一 per-file 裁剪,而是把整套下压 conjuncts 挂在 scan-node 上。 + +**影响**:无正确性影响,仅极轻微的 BE 冗余计算。具体示例:一张按 `dt` 分区的 iceberg 表,查询 `WHERE dt='2026-01-01' AND val>10`。命中 `dt='2026-01-01'` 分区的数据文件,其 SDK per-file residual 会退化为仅 `val>10`(dt 谓词已由分区值满足);但 Doris 下发给 BE 的是整套 `dt='2026-01-01' AND val>10`,BE 对该分区每个文件的每一行仍会重复评估恒真的 `dt='2026-01-01'`。**结果完全正确**,只是多做一次恒真判断,开销可忽略。与 legacy 行为一致。 + +**是否需修复**:不需要作为缺陷修复。这是有意的、与 legacy 对齐的行为,severity 🟡/S 合理。若未来要做 per-file residual 下压优化,需在 `IcebergScanRange`/thrift 增 per-range residual 字段、BE 支持 per-split 覆盖 scan-node conjuncts —— 属大改且收益薄(仅省去恒真分区谓词的逐行判断),不建议在本迁移分支内做。 + +--- + +## 本类别小结 + +**真问题(需处理)**:仅 #21(`ConnectorDeleteFile` 欠建模/死代码)与 #26(iceberg residual 非 per-range 下发)判

迁移的一个核心张力——**文件级(per-file/per-split)语义如何在保持通用节点 connector-agnostic 的前提下正确传递**。项目选定的范式是「通用节点不含 source-specific 逻辑,per-connector 差异经能力位 SPI(`adjustFileCompressType`)或连接器自带 typed

表级统计 `IcebergConnectorMetadata.computeRowCount`（IcebergConnectorMetadata.java:746-768）：首取 `table.currentSnapshot().summary()`（**snapshot 级，非表级静态公式**）；三个计数器 `total-equality-deletes` / `total-records` / `total-position-deletes` 任一为 null → 返回 -1（761-762，兼容 compaction/overwrite 快照可能省略计数器，避免旧代码 `Long.parseLong(null)` NPE）；`total-equality-deletes != "0"` → 返回 -1（764-765）；否则 `total-records - total-position-deletes`（767，**已扣除 position delete，delete-aware**）。`getTableStatistics`（715-734）再把 `rowCount<=0` 折叠成 `Optional.empty()`（对应 legacy "0 -> UNKNOWN" 语义，系统表直接 empty）。 +- COUNT(*) 下推 `IcebergScanPlanProvider.getCountFromSummary`（IcebergScanPlanProvider.java:2295-2306）：共享同一 null-guard（2299）与 equality-delete gate——`equalityDeletes != "0"` → `return -1` 不下推（2303-2304）。另 `mayHaveEqualityDeletes` 类逻辑（1757-1759）亦按 `total-equality-deletes` 判断。 +- 两处代码注释均明标为 legacy `IcebergUtils.getCountFromSummary` 的忠实移植（upstream 32a2651f66b，#64648），且本就是 delete-aware。 + +**详解（主张为何不成立）**：主张的三点逐条与代码相反—— +- "行数用表级公式而非 snapshot·delete-aware"：错。`computeRowCount` 读的是 `currentSnapshot().summary()`（IcebergConnectorMetadata.java:747），是 snapshot 级；并从 `total-records` 扣除 `total-position-deletes`（767），是 delete-aware。 +- "equality-delete 未从行数扣除/gate"：错，恰好相反。equality delete 在读时需重投影、summary 无法精确净出，所以代码**显式** gate 到 -1（computeRowCount:764-765；下推:2303-2304），position delete 则被扣除。 + +即"未 gate equality delete"恰是代码刻意避免的场景，主张方向完全反了，可能基于过时或误读的代码。 + +**具体反例验证主张站不住**：一张带 `total-equality-deletes="5"` 的 iceberg 表，`computeRowCount` 走到 764-765 直接返回 -1，`getTableStatistics` 返回 `Optional.empty()`，CBO 拿到 UNKNOWN 而**不会**用未扣 equality delete 的 `total-records` 错误行数；COUNT(*) 下推路径同样在 2303-2304 return -1 不下推。主张担忧的"用未扣 equality delete 的行数"场景在代码里根本不可达。 + +**结论**：REFUTED，高置信，无需修复。若报告本意是"equality-delete 情况下行数退化为 UNKNOWN（而非精确估）"，那是有意的保守设计（summary 无法精确净出 equality delete），并非缺陷。 + +--- + +## #15 getTableStatistics 无 snapshot 参数 +

`computeRowCount` 用 `table.currentSnapshot()`；`FOR VERSION AS OF ` 查询下优化器拿 latest 行数、scan 读 pinned old 快照 → stats/scan 粒度偏斜（仅估计，不错结果）；schema 已原子 pin、stats 没有。 + +**核实过程**： +- SPI 签名 `ConnectorStatisticsOps.getTableStatistics(ConnectorSession session, ConnectorTableHandle handle)`（ConnectorStatisticsOps.java:32-36）不含任何 MvccSnapshot/version 参数；同接口 getColumnStatistics/estimateDataSizeByListingFiles/listFileSizes 均无快照维度。 +- fe-core 消费点 `PluginDrivenExternalTable.fetchRowCount()`（PluginDrivenExternalTable.java:1148-1160）：session 来自 `buildCrossStatementSession()`（1152，跨查询作用域、缓存性质，天然非 per-query），经 `resolveConnectorTableHandle`（1155）→ `getTableStatistics`（1160）。 +- `resolveConnectorTableHandle`（PluginDrivenExternalTable.java:116-120）仅调 `metadata.getTableHandle(session, dbName, getRemoteName())`，不 thread 任何快照/版本。 +- iceberg 实现 `IcebergConnectorMetadata.getTableStatistics`（IcebergConnectorMetadata.java:716-734）→ `computeRowCount(loadTable(session, iceHandle))`；`computeRowCount`（746-767）首行即 `Snapshot snapshot =

同形：`getTableStatistics(session, handle)`（PaimonConnectorMetadata.java:1183-1194）→ `catalogOps.rowCount(resolveTable(paimonHandle))`，handle 无快照维度。 +- 对照 schema 路径：`getPartitionColumns` / `getFullSchema` / `getNameToPartitionItems`（PluginDrivenExternalTable.java:632/689/807）均带 `Optional` 并经 `getSchemaCacheValue(snapshot)` pin——证实"schema pin、stats 不 pin"的不对称成立。 +- verify 补充：`getNameToPartitionItems`（807-855）虽签名带 snapshot，内部仍走无快照的 `resolveConnectorTableHandle`（821）+ `listPartitions(..., Optional.empty())`（831），即分区枚举同样非快照 pin——说明这是一族既有局限（与 P6-1 stats-grain 同源），非 stats 单点特例。 +- legacy 对照：master 分支 `IcebergUtils.getIcebergRowCount` 同样无条件 `icebergTable.currentSnapshot()`（无时间旅行感知），证实连接器是忠实端口，非迁移引入的回归。 + +**背景**：统计 SPI 的签名与 schema 系列 SPI 形成不对称——后者能把查询时点解析出的快照原子 pin 进 handle，而 fetchRowCount 经 `resolveConnectorTableHandle` 拿一个"裸"handle。因此行数天生是"表级、latest 快照"的口径，且 session 来自跨查询缓存作用域，更不可能携带某条查询的时间旅行时点。 + +**影响（具体示例）**： +输入：iceberg 表 `t` 有快照 S1（100 万行）后追加到快照 S2（300 万行，当前）。查询 `SELECT ... FROM t FOR VERSION AS OF JOIN big ON ...`。 +- 扫描侧经 MVCC applySnapshot 正确 pin 到 S1，只读 100 万行数据文件； +- 但 CBO 走 fetchRowCount → getTableStatistics → computeRowCount（currentSnapshot=S2）= 300 万，优化器按 300 万做基数估计和 join reorder。 +- 后果：stats 与真实扫描量偏斜 3 倍，可能选出次优的 join 顺序/分布方式/build-probe 侧。 +- **关键限定**：这只影响执行计划的代价估计，**不改变结果正确性**——扫描输出仍是 S1 的 100 万行真实数据。反向（FOR VERSION AS OF 一个后续被 DELETE 压缩的更"重"历史快照）则会低估。paimon time-travel 上同构。 + +**修复方案（可选、非必须）**：与 P6-1 stats-grain 是同族问题。若要真正修复，给统计 SPI 增加快照维度——`getTableStatistics` 签名引入 `Optional`（或让 fetchRowCount 侧把查询时点解析的快照 thread 进 handle），iceberg 侧改用 `table.snapshot(snapshotId)` 而非 currentSnapshot，paimon 类同。约束：(a) fetchRowCount 现走跨查询缓存 session，行数被 ExternalRowCountCache 缓存复用，做成 per-snapshot 需重设缓存键，成本不小；(b) 收益仅 CBO 估计精度、不涉正确性。综合看，保持现状（接受估计偏斜）是合理工程取舍，修复应与 schema/stats/partition 快照粒度统一治理时一并做，而非单点改。严重度 S/orange + "仅估计"标注公允甚至略偏保守。 + +--- + +## #16 getNewestUpdateTimeMillis 名说毫秒实微秒 + +**核实结论**：**PARTIAL**（高置信）。命名/单位错配为 CONFIRMED 事实，但非 S 级正确性缺陷（PARTIAL 成立）。**最终以 verify 为准**：verify `agrees=false`，因为 stage-1 的核心论据（"唯一消费者是 Dictionary"、"从不与任何 millis 量做算术"）**事实错误**——存在第二类消费者 CacheAnalyzer 确实把该微秒值与 wall-clock 毫秒混算。但该算术足迹的后果是良性的，故 severity 判 PARTIAL 仍成立。 + +**原报告主张**：`getNewestUpdateTimeMillis` 名字说 millis，但源（iceberg）定义是微秒，单位错配。 + +**核实过程**： +- SPI 定义 `ConnectorMvccPartitionView.getNewestUpdateTimeMillis()`（ConnectorMvccPartitionView.java:113），返回字段 `newestUpdateTimeMillis`（70），方法名带 "Millis" 后缀。javadoc（101-111）明写"单位由源定义、iceberg 为 MICROSECONDS、勿当 millis / 勿转换、只依赖单调性、与 master parity"。 +- iceberg 实现：`IcebergPartitionUtils.java` 从 PARTITIONS 元数据表 `row.get(9)` 读 `last_updated_at`（769-770 行布局注释，806 `lastUpdateTime=row.get(9,Long)`，iceberg 微秒），`newestUpdateTimeMillis = max(lastUpdateTime)`（603-604），传入 view 构造器（605-606）。名义 millis、实际 micros，错配属实。 +- range-view 透传：`PluginDrivenMvccExternalTable.java:815-823` 的 range-view 路径返回 `pin.getNewestUpdateTimeMillis()` 作为 `getNewestUpdateVersionOrTime()`。 +- 消费者复核（verify 关键补充）：grep `getNewestUpdateVersionOrTime` 全部 caller，发现 stage-1 漏判的第二类消费者： + - **Dictionary.java:271-296**

分区新鲜度探针的载荷，javadoc 明确要求调用方"只依赖单调性、从不依赖绝对刻度"，并与 master `IcebergExternalTable.getNewestUpdateVersionOrTime = max(partition.lastUpdateTime)` 逐字对齐。绝大多数消费者（Dictionary、SqlCacheContext、NereidsSqlCacheManager）确实只做单调/等值比较。 + +**影响（具体示例）**： +- 单调探针路径（Dictionary）：一张按 DAY transform 分区的 iceberg 表，某次探针取到 `last_updated_at = 1_700_000_000_000_000`（微秒）；写入新数据后快照更新，下次取到更大微秒值；`hasNewerSourceVersion` 判 `新值 > srcVersion` → 触发字典刷新。无论单位 micros/millis 结果一致，无失效路径。 +- **wall-clock 混算路径（CacheAnalyzer，verify 揭示的真实算术足迹）**：iceberg 微秒（~1.7e15）恒大于 epoch 毫秒（~1.7e12）。经 `now = Math.max(nowtime(), latestPartitionTime)` 把 `now` 抬到微秒刻度；:263 只对全局最大值持有者判 gate，`now == 该最大值` → 差值 ≈ 0 → "数据已静默 ≥ 30s"闸门**永不通过** → 触及该 iceberg 表的查询**实质上永不启用 SqlCache**。这是缓存**被安全抑制**（correctness-safe：不会误命中陈旧结果、不会误启用缓存），且与 master 行为一致（master 同样返回微秒）。因此**不构成正确性 bug**，只是 iceberg 表默默拿不到 SqlCache 的性能优化。 + +**为何仍判 PARTIAL 而非 S 级**：命名/单位错配是 CONFIRMED 的客观事实，但唯一真实的算术足迹（CacheAnalyzer）后果良性（安全抑制 + master parity），不存在"什么表/什么查询 → 错误结果"的可复现失效路径。故 severity 判 PARTIAL 成立。**须更正 stage-1 的错误表述**："零算术消费者 / 唯一消费者 Dictionary"是错的；正确表述为"存在一处 wall-clock 毫秒算术消费者（CacheAnalyzer），但其后果仅为 iceberg SqlCache 被安全抑制且与 master parity，故不构成正确性缺陷"。 + +**修复方案（低优先级，纯整洁化）**：若清理重命名，把方法/字段更名为不带单位语义的名字（如 `getNewestUpdateMonotonicMarker()`），同步 ConnectorMvccPartitionView.java、PluginDrivenMvccSnapshot.java:173、IcebergPartitionUtils.java:603 及相关测试。**根因值得一并标注**：CacheAnalyzer 端 `latestPartitionTime` 同时承载"毫秒时间戳"与"不透明版本 token"两义（把该 token 与

file:line，逐条吻合，仅补两点非纠正性说明。 + +**原报告主张**：`ConnectorMvccSnapshot` 是定点（snapshotId+schemaId），但 branch 是移动引用（head 会进）；applySnapshot 路由到 `scan.useRef(name)`，scan 跟 branch head（忽略 pin 的 snapshotId），而 schema/stats 定点；plan→scan 之间对 branch 的 schema-changing commit → BE 用旧 schemaId 读新 schema 数据 → 列错配/错行/崩溃；破了 pin 的 query 内一致版本契约。 + +**核实过程**：主张描述的每个单点机制在代码中逐一存在，但据以推导的 bug 前提（plan→scan 之间 branch head 会移动）被"每语句只加载一次表"的作用域堵死。 +- pin 捕获 `IcebergConnectorMetadata.resolveRef`（IcebergConnectorMetadata.java:1787-1798）：对 BRANCH/TAG/VERSION_REF 按 REF NAME 定点——`snapshotId = ref.snapshotId()`（1794）、`schemaId = SnapshotUtil.schemaFor(table, refName).schemaId()`（1792）、ref 名塞进 REF_PROPERTY（1796），均来自传入的 table。 +- `resolveTimeTravel`（1733-1735）对 BRANCH 走 `resolveRef(..., SnapshotRef::isBranch)`（1766），而 pin 捕获经 `loadTable(session, handle)`（625）→ `resolveTableForRead`（641-647）→ `IcebergStatementScope.sharedTable`。 +- `applySnapshot`（1821-1834）把 snapshotId + ref + schemaId 一起 `withSnapshot` 到 handle（1833）。 +- scan 侧 `IcebergScanPlanProvider.buildScan`（IcebergScanPlanProvider.java:1099-1124）：`if (handle.getRef()!=null) scan = scan.useRef(handle.getRef())`（1106）else `useSnapshot`（1108），在冻结的 `table` 上。 +- schema 定点：dict schema `pinnedSchema`（1141-1150）按 `handle.getSchemaId()` 取 `table.schemas()`；slot schema `getTableSchema(...,snapshot)`（IcebergConnectorMetadata.java:448-468）按 `snapshot.getSchemaId()`。二者绑同一被捕获的 schemaId（经 applySnapshot withSnapshot 1833 回填），注释（1131-1139 / 460-464）强制两侧 fallback 字节一致（SIGABRT 防护不变式）。 +- **决定性证据——三条路径读同一个每语句冻结的 Table 实例**：`IcebergStatementScope.sharedTable`（IcebergStatementScope.java:59-67）key = `"iceberg.table:"+catalogId+":"+db+":"+tbl+":"+queryId`，`session.getStatementScope().computeIfAbsent(key, loader)`——同一 queryId 下 pin 路径（resolveTableForRead 641-647）与 scan 路径（resolveTable，IcebergScanPlanProvider.java:2341-2358）key 完全相同，loader 至多跑一次，后到者复用同一 RAW Table 对象。类注释（31-47）明说 read metadata / scan planning / write 都解析同一张表。 +- verify 补充：作用域不仅堵住"两次远端 reload"，还屏蔽跨查询 tableCache 在 pin 与 scan 之间刷新——loader 只为首个调用者运行（ScanProvider 2348-2357 / Metadata 643-646），后到者恒拿 scope 内已冻结对象，与 tableCache 当前内容无关。 + +**为何非问题**：主张的失败场景要成立，必须在同一条 SELECT 内发生两件事：(a) pin 阶段从 branch 读到 schemaId=S_old；(b) scan 阶段 useRef 又从远端读到已推进的新 head（schema=S_new 的新数据）。只有当 pin 与 scan 分别触发两次独立远端 loadTable 时，这个"中间 commit"窗口才存在。而 `IcebergStatementScope` 保证单条语句对某张表只加载一次并冻结，useRef 是在这份不可变的内存 TableMetadata 上解析 branch，永远解析回 pin 时捕获的同一个 `ref.snapshotId()`，其 schema 恰是被定点的 schemaId。 + +**具体反例验证主张站不住**：表 `db.t` 有 branch=b1（head=snap_100，schema=S5）。执行 `SELECT * FROM t FOR VERSION AS OF 'b1'`： +- resolveRef 在 statement scope 首次加载 Table@T0，得 snapshotId=100、schemaId=5、REF_PROPERTY=b1。 +- 即便此刻别的 writer 向 b1 提交了 snap_200（schema 演进为 S6）， +- buildScan 复用同一个 Table@T0（scope 命中，不再 reload），`useRef("b1")` 在 T0 的 refs 上解析 → 仍是 snap_100；dict/slot schema 仍是 S5。 +- BE 拿到的是 (snap_100 数据 + S5 schema)，完全自洽，不会出现"用 S5 读 S6 数据"。 +- 要读到 snap_200 只能是下一条 query（新 queryId → 新 scope → 新加载），那时 pin 与 scan 又各自基于 T1 自洽。跨 query 读到更新的 head 是 branch 的正确语义（移动引用本就该跟 head），不是 bug。 + +**其他说明**： +- `useRef` 而非 `useSnapshot(ref.snapshotId())` 纯为 legacy parity（注释 IcebergScanPlanProvider.java:1102-1103、IcebergConnectorMetadata.java:1785、IcebergTableHandle.java:34-38），在冻结元数据上二者等价，无副作用。 +- 唯一"每次都加载"的分支：`sharedTable` 在 `session==null`（离线/直构造单测）或 `ConnectorStatementScope.NONE`（离线 planning）下每次 loadTable（IcebergStatementScope.java:43-46,60-62）。但那是无活跃语句的离线路径；生产 SELECT 持有真实 StatementContext scope，读侧走 computeIfAbsent 单次加载，无此窗口。 + +**结论**：主张把"branch 是移动引用 + useRef 跟 head"正确识别为机制，但错误假设 pin 与 scan 会二次 reload 从而暴露移动窗口；实际由 `IcebergStatementScope` 保证 query 内单次冻结加载，一致性契约被保证而非被破坏。评为 REFUTED，高置信。 + +--- + +## #18 FOR TIME AS OF 数字串当 epoch + +**核实结论**：**PARTIAL**（高置信）。investigate 与 verify 一致：机械事实 CONFIRMED（数字正则 → 当 epoch），"date/epoch 歧义/bug"定性 REFUTED，整体 PARTIAL、严重度低。verify 补两点非纠正说明。 + +**原报告主张**：FOR TIME AS OF 用数字 regex 判定，数字串被当 epoch，产生 date/epoch 歧义。 + +**核实过程**： +- fe-core `PluginDrivenMvccExternalTable.toTimeTravelSpec`（PluginDrivenMvccExternalTable.java:430-431）：当 `snap.getType()==VersionType.TIME` 时 `return ConnectorTimeTravelSpec.timestamp(value, isDigital(value))`。TIME 分支无条件把 digital 标志透传给连接器，fe-core 不做 datetime 校验（source-agnostic 分派）。 +- `isDigital`（452-453）= `DIGITAL_REGEX.matcher(value).matches()`，`DIGITAL_REGEX = Pattern.compile("\\d+")`（99，注释标 parity `PaimonUtil.isDigitalString`）——即纯数字串。 +- SPI 契约 `ConnectorTimeTravelSpec`（ConnectorTimeTravelSpec.java:43-46,118-128）：digital=true 表示 value 已是 epoch-millis，false 表示待解析 datetime 串。 +- iceberg `IcebergConnectorMetadata.parseTimestampMillis`（IcebergConnectorMetadata.java:1806-1812）：`if (spec.isDigital()) return Long.parseLong(getStringValue())`（当 epoch 毫秒），否则 `IcebergTimeUtils.datetimeToMillis(...)` 按 session 时区解析。结果喂 `SnapshotUtil.snapshotIdAsOfTime`（1749-1752）。javadoc（1800-1804）明写 legacy 一贯按 datetime 串解析、数字值本会失败，honoring digital 是 "benign superset"。 +- `IcebergTimeUtils.java:49` `DATETIME_FORMAT = ofPattern("yyyy-MM-dd HH:mm:ss")`，datetimeToMillis（97-99）用它 `LocalDateTime.parse`——合法 datetime 字面量必含 `-`/`:`/空格，`isDigital` 对其恒 false，无 date/epoch 交叠歧义。 +- paimon 对齐：`PaimonConnectorMetadata.java:694-695` 同样 `if (spec.isDigital()) return Long.parseLong(value)`，注释（672-673）标忠实复刻 legacy `PaimonUtil.getPaimonSnapshotByTimestamp`。 +- verify 补充：当前工作树中 legacy iceberg 的 FOR TIME AS OF 解析代码已被删除（`fe-core/.../datasource/iceberg/` 下无 timeStringToLong/snapshotIdAsOfTime/VersionType.TIME 命中），故"legacy 把数字值当 datetime 解析会失败"这一对照现基于 IcebergConnectorMetadata.java:1800-1804 与 IcebergTimeUtils.java:47-53 的 byte-parity 注释佐证，而非现存 legacy 源码——不影响结论。 + +**为何"歧义"定性夸大（REFUTED 部分）**：合法 datetime 字面量（`2023-01-01 00:00:00`）恒含非数字字符，`isDigital` 永远为 false，永远走 datetime 分支，不会被误当 epoch。真实日期与 epoch 之间没有任何交叠歧义。唯一会被当 epoch 的是"裸整数串"，而裸整数在 legacy 下从来不是合法 FOR TIME AS OF 输入。 + +**影响（具体示例）**： +- 合理用法：`SELECT * FROM ice_tbl FOR TIME AS OF '1700000000000'` → digital=true → epoch 1700000000000ms（2023-11）→ `SnapshotUtil.snapshotIdAsOfTime`。这是使用者显式想按 epoch 取的合理用法。 +- 误报级边角：`FOR TIME AS OF '20231001120000'`（用户以为是紧凑日期 yyyyMMddHHmmss）→ digital=true → 被 parseLong 当成 epoch 毫秒（约公元 2611 年）。verify 澄清机制：`SnapshotUtil.snapshotIdAsOfTime` 对晚于所有快照的时刻**静默返回最新快照**（仅当早于首个快照才抛异常 → 被 catch 成 empty，见 1720 注释），而非报错。注意：此紧凑格式在 Doris 下从来不是合法 datetime 输入，legacy iceberg 对它会 `datetimeToMillis` 解析失败抛异常；新连接器把它当 epoch 属于"更宽松地接受"而非在合法日期语义下静默误判——且 :1800-1804 明确记为有意的 benign superset。 + +**为何非缺陷 / 属既定设计**：digital → epoch 路径是跨连接器统一的既定契约：paimon:694-695 同样 parseLong 并标忠实复刻 legacy；`ConnectorTimeTravelSpec` javadoc（43-46,118-128）把"digital ⇒ epoch-millis 字面量"写进 SPI 契约；iceberg 侧有意镜像该语义并成文说明。 + +**结论**：机械事实为真（CONFIRMED 部分），但"date/epoch 歧义"危害定性不成立（REFUTED 部分）——合法日期串不会落入 epoch 分支，真正受影响的仅是本就非法的裸整数输入，且系有意对齐设计。整体 PARTIAL，实际严重度低。若仍要收紧，可在 fe-core 分派处对 TIME 类型不打 digital 标志（强制走 datetime 解析），或对紧凑数字串给出明确 "unsupported datetime format" 报错而非静默当 epoch；但这会破坏与 paimon 的既有对齐，需产品层拍板，不宜按 bug 直接改。 + +--- + +## #24 getFreshnessValue 一 long 两粒度 + +**核实结论**：**PARTIAL**（高置信）。investigate 与 verify 一致：字面观察正确（一 long 两种粒度），但由并列判别枚举完全化解歧义，非缺陷。verify 独立复核全部位点，并纠正 stage-1 analysis 草稿一处自相矛盾的括注（不影响 verdict）。 + +**原报告主张**：`getFreshnessValue` 一个 long 承载两种粒度——snapshot-id 或 millis（取决于源），语义歧义。 + +**核实过程**： +- `ConnectorMvccPartition.getFreshnessValue()`（ConnectorMvccPartition.java:49/82-84）确为单个 long，javadoc 明写"snapshot id or epoch-millis timestamp, per the view's freshness kind"。字面主张成立。 +- 判别标签在同一对象图上：`ConnectorMvccPartitionView.Freshness` 枚举 `{SNAPSHOT_ID, LAST_MODIFIED}`（ConnectorMvccPartitionView.java:59-65），javadoc 各自绑定 `MTMVSnapshotIdSnapshot` / `MTMVTimestampSnapshot`；构造器（72-74）payload 与标签一次传入，原子绑定，不存在"给了值忘了给粒度"的窗口。 +- 传递侧：`PluginDrivenMvccExternalTable.java:213-214` 读 `view.getFreshness()==SNAPSHOT_ID` 固化为 boolean `snapshotIdFreshness`；:229 存 per-partition freshnessValue；:232-233 一并进 pin（PluginDrivenMvccSnapshot.java:62/122/165-166）。 +- 消费侧 `getPartitionSnapshot`（PluginDrivenMvccExternalTable.java:680-711）：先无条件查 `pin.isSnapshotIdFreshness()`（688）→ `MTMVSnapshotIdSnapshot(value)`（692）；否则按 `isLastModifiedFreshness`（hive on-demand probe，702-706）或 pin-timestamp（710，`MTMVTimestampSnapshot`）分派。无"拿到 value 不知粒度"的路径。 +- 实际使用者收敛：iceberg 建 view 时两处（空表分支 557-558 + 正常分支 605-606，构造 partition 596）均**硬编码 `Freshness.SNAPSHOT_ID`**，恒发 snapshot-id、从不发 LAST_MODIFIED；paimon 不 override `getMvccPartitionView`（PaimonConnectorMetadata.java:105 / PaimonConnector.java:137），走默认 LIST/timestamp 路径，根本不经此 range-view long；hive override 仅委派给 sibling metastore（HiveConnectorMetadata.java:1399-1402）。 + +**为何不是 bug（PARTIAL）**：这个 long 是一个带标签联合（tagged union）的负载字段，判别标签始终在同一对象图上，消费侧无条件按标签分派，属标准 tagged-union 模式，不产生错误结果。构造不出"什么表/什么查询 → 什么错误结果"的例子：任何取用 freshnessValue 处都先读判别位。若强行让 iceberg 发错标签，那是连接器自身 bug，与"一个 long 两粒度"的 API 设计无关。当前 range-view 路径唯一实现者是 iceberg 且恒为 SNAPSHOT_ID，两粒度并存只是 API 面预留、实运行不共存。定性符合报告自评 🟡/S/潜伏。 + +**须更正 stage-1 一处笔误（不影响 verdict）**：stage-1 analysis 草稿写"snapshot-id 连接器（iceberg/paimon）永不落入 timestamp 分支"——**不准确**。paimon 恰是 timestamp 连接器：不 override range-view，`getPartitionSnapshot` 中落入 710 行 `MTMVTimestampSnapshot`（pin-timestamp 分支），即"落入 timestamp 分支"。正确表述：**iceberg 走 snapshot-id 分支、paimon 走 pin-timestamp 分支，二者均不触达 hive 的 on-demand probe（694-706，由 isLastModifiedFreshness 门控）；真正会读 timestamp 语义的正是 paimon**。源码 698-699 注释 "a snapshot-id connector (paimon/iceberg) NEVER reaches the probe" 中的 (paimon/iceberg) 是"非 hive"的宽松分组，非指 paimon 用 snapshot-id 语义。stage-1 的 code_reality 段本身已正确写明"paimon 走 LIST/timestamp 路径"，此仅为草稿括注与 code_reality 之间的自相矛盾。 + +**修复方案**：非必需。若要进一步消除 API 面表意负担，可把 payload 拆成语义命名的两个 getter，或引入小的值对象承载 (kind,value)；但属 taste 级重构，且会碰本项目"fe-core/SPI 只减不增、surgical"纪律，收益极薄，删旧代码期不建议动。 + +--- + +## #25 ConnectorMvccSnapshot 无 equals/hashCode + +**核实结论**：**CONFIRMED**（高置信）——严格限定为主张自己声明的 minor/latent "shape smell"范畴，非功能缺陷。investigate 与 verify 一致，verify 仅指出 stage-1 若干行号轻微漂移及一点补充（四个兄弟类还都定义了 toString）。 + +**原报告主张**：4 个 MVCC/stats 兄弟类（Partition/View/TimeTravelSpec/TableStatistics）都定义了 equals+hashCode，唯 `ConnectorMvccSnapshot` 没有 → 不能按 (table,version) 做 value-key，shape smell。 + +**核实过程**： +- `ConnectorMvccSnapshot`（ConnectorMvccSnapshot.java:34-150）是 final class，含 6 字段（snapshotId/timestampMillis/description/schemaId/properties/lastModifiedFreshness）+ Builder，body 末尾直接是 `build()`（约 148），**没有** override equals/hashCode/toString（verify 通读全文 1-150 确认）。 +- 四个兄弟类均有完整 equals+hashCode+toString：ConnectorMvccPartition（equals@88, hashCode@103, toString@108）、ConnectorMvccPartitionView（equals@118, hashCode@133, toString@138）、ConnectorTimeTravelSpec（equals@192, hashCode@207, toString@212）、ConnectorTableStatistics（equals@51, hashCode@63, toString@68）。 +- 两个 fe-core 包装类也都无 equals/hashCode：`ConnectorMvccSnapshotAdapter.java:32-41`（仅持有 snapshot + getSnapshot()）、`PluginDrivenMvccSnapshot.java:54-141`（持有 connectorSnapshot 字段并 delegate getters）。 +- 全仓 grep `ConnectorMvccSnapshot` 的 value-key 用法（`.equals`/`.hashCode`/`Set<`/`Map<` key/distinct/contains/HashSet）→ **零命中**。生产者 HudiConnectorMetadata:503（+ paimon 测试），消费者 PluginDrivenMvccExternalTable:380（`resolved.get()`），测试走逐字段 getter 断言。它只作为不透明 pin 按引用穿过查询生命周期（beginQuerySnapshot 产出 → 包进 adapter/PluginDrivenMvccSnapshot → BE 序列化边界 unwrap）。 +- verify 行号更正（annotation/javadoc 偏移，非实质）：ConnectorTimeTravelSpec equals @192（stage-1 记 191-209）、ConnectorTableStatistics equals@51/hashCode@63（stage-1 记 50-65）。补充：四兄弟均定义 toString，真正 parity 目标是 3 方法（equals+hashCode+toString）而非 2；stage-1 已把 toString 标为可选，无实际 gap。 + +**背景**：MVCC/stats 值对象家族里，四个 immutable value 类都实现了逐字段 equals+hashCode，同族的 ConnectorMvccSnapshot 独缺，构成家族内一致性缺口（shape smell）。 + +**影响评估——零运行时影响**：当前没有任何真实输入/表/查询会因此产生错误结果。所有使用点均不对其做 value 比较：既不作 Map/Set key，也不 distinct/contains，两个包装类同样无 equals/hashCode。主张里"不能按 (table,version) 做 value-key"是**假设性**能力缺失而非被现有代码踩中的路径。假想示例：若将来有人用 `Set` 对同一表同一 snapshotId 的两次 begin 结果去重、或写单测 `assertEquals(expectedSnapshot, actual)`，会退化为 identity 比较从而"永不相等"——但今天不存在这样的调用点，单测走逐字段 getter 断言。主张自评 🟡/S/潜伏，与代码现实吻合，无低估无夸大。 + +**修复方案（低优先级，纯一致性收敛）**：给 ConnectorMvccSnapshot 补一组 override，与兄弟类同风格：equals 覆盖 snapshotId/timestampMillis/schemaId/lastModifiedFreshness/description/properties 六字段（`==` 比三个 long/boolean，`Objects.equals` 比 description，`Map.equals` 比 properties），hashCode 用 `Objects.hash` 同集合，可顺带补 toString。该类已 import `java.util.Objects`，无需新增依赖，改动局限单文件、不碰任何调用方，符合 surgical 原则。鉴于零运行时影响，亦可选择不修、仅作为 backlog 一致性项跟踪。 + +--- + +## 本类别小结 + +**真问题（CONFIRMED，但均限定严重度）**： +- **#15**（stats 无 snapshot 参数）——唯一"真实但有边界"的问题：time-travel 下行数恒取 currentSnapshot 与 schema 已 pin 形成不对称，导致 CBO 基数估计偏斜；但**仅影响估计、不错结果**，且是 legacy `IcebergUtils.getIcebergRowCount` 的忠实端口、非迁移回归。 +- **#25**（ConnectorMvccSnapshot 缺 equals/hashCode）——纯**形态/一致性 smell**，零运行时影响，backlog 项。 + +**伪问题 / 定性夸大（PARTIAL / REFUTED）**： +- **#5**（iceberg 行数丢 equality-delete gate）——**REFUTED**：主张的三项断言全部反了。行数取 `currentSnapshot().summary()`（snapshot 级）、扣除 position delete（delete-aware）、并对 equality delete 显式 gate 到 -1/UNKNOWN（computeRowCount:764-765、下推:2303-2304），两处均为 legacy `IcebergUtils.getCountFromSummary`（#64648）的忠实 delete-aware 移植；属方向性误读，无需修复。 +- **#16**（微秒/毫秒命名错配）——事实成立但非 S 级；verify 纠正 stage-1"零算术消费者"的错误，真相是 CacheAnalyzer 确有 wall-clock 混算，但后果为**安全抑制** iceberg SqlCache（correctness-safe + master parity）。 +- **#17**（branch ref 移动）——**REFUTED**：机制单点属实，但 `IcebergStatementScope` 每语句单次冻结加载令 plan/scan 复用同一冻结 Table，移动窗口不存在。 +- **#18**（数字串当 epoch）——PARTIAL：合法 datetime 字面量必含非数字字符恒不误判，"歧义"夸大，且系跨连接器有意对齐设计。 +- **#24**（一 long 两粒度）——PARTIAL：tagged-union，判别枚举始终在场，消费侧无条件分派，构造不出失败场景。 + +**共性根因**： +1. **快照 pin 的粒度不统一**（#15 核心，#16/#17/#18 相关）——catalog SPI 已把 schema 系列做成快照感知（`Optional`），但 stats 与 partition 枚举路径仍走无快照的 `resolveConnectorTableHandle` + currentSnapshot。这是一族既有局限（与 P6-1 stats-grain 同源），应统一治理而非单点改。 +2. **legacy parity 优先于命名/单位纯净**（#16、#18）——多处刻意保持与 master 逐字对齐（微秒透传、digital→epoch benign superset），带来命名/单位表意负担，但均被消费侧的单调比较/判别位化解，不产生正确性问题。 +3. **多条主张把"存在某机制"误当"存在某 bug"**（#17、#24、#18）——报告正确识别了移动引用、tagged-union payload、数字正则等机制，但错误假设它们会在运行时被踩中；实际由 statement scope（#17）、判别枚举（#24）、字面量格式约束（#18）精确堵死。 + +**与其他类别的关联**：#15 明确指向 **P6-1 stats-grain**（快照粒度族问题），#17/#18 依赖 **IcebergStatementScope / 每语句单次加载**（见项目 memory「iceberg 表解析/缓存作用域」与「session=user 目录无活跃跨查询缓存」），#16 触及 **query-cache（SqlCache）** 子系统的 wall-clock 语义。若后续统一治理"快照粒度"，应把 stats（#15）、partition 枚举（#15 verify 补充）、以及 #16 的新鲜度 token 语义一并纳入，而非逐条打补丁。 diff --git a/plan-doc/catalog-spi-mismatch/analysis-F-write-txn-ddl.md b/plan-doc/catalog-spi-mismatch/analysis-F-write-txn-ddl.md new file mode 100644 index

声明：`ConnectorWriteHandle.getWriteContext()` 返回 `Map`，javadoc 明写 "Free-form write context: static partition spec, write path, and other connector-defined keys"（fe-connector-api/.../handle/ConnectorWriteHandle.java:47-51）。verify 额外指出**同一文件的类级 javadoc**（ConnectorWriteHandle.java:31-34）也复刻了同样的过度承诺措辞 "...whether it is an OVERWRITE, and a free-form write context (static partition spec, write path, etc.)"——即误导有**两处** locus。 +- 唯一生产路径：`PluginDrivenTableSink.bindDataSink` 中 writeContext 初始化为 `Collections.emptyMap()`（:164），唯一赋值 `writeContext = ctx.getStaticPartitionSpec()`（:169）；EXPLAIN 路径传 `Collections.emptyMap()`（:146）；字段 / 参数 / accessor 均命名通用 `writeContext`（:191/197/202/234-235）。确认唯一生产路径只塞静态分区 spec，不塞任何第二种 key。 +- 上游来源：`PluginDrivenInsertCommandContext` 字段名为 `staticPartitionSpec`，类注释自称 "static partition spec — a generic col -> val map"（PluginDrivenInsertCommandContext.java:29-32）；`setStaticPartitionSpec` 的全部 caller（grep 整个 fe-core）仅 InsertOverwriteTableCommand.java:432 与 InsertIntoTableCommand.java:526 两处，均静态分区场景，无第三生产者。 +- 全部消费者一律作静态分区值用：iceberg 仅在 OVERWRITE 且非空时 `setStaticPartitionValues(handle.getWriteContext())` 并塞进 IcebergWriteContext（IcebergWritePlanProvider.java:375、:420-421）；hive 传入 `HiveWriteContext.getStaticPartitionValues`（HiveWritePlanProvider.java:161 → HiveWriteContext.java:69）；maxcompute 局部变量直接命名 `staticPartitionSpec`（MaxComputeWritePlanProvider.java:100-101/133）。 +- javadoc 承诺的 "write path" 从不经此 map：hive writePath 由 `createTempPath`/`normalizeStorageUri` 独立算（HiveWritePlanProvider.java:152-156），iceberg 输出路径走 `resolveLocationFields`（IcebergWritePlanProvider.java:409-416），均与 writeContext 无关。 + +**背景**：catalog SPI 把写请求收敛到 `ConnectorWriteHandle`。静态分区（`INSERT INTO t PARTITION(a=1)` / `INSERT OVERWRITE ... PARTITION`）本是明确的 `col -> val` 语义结构，但 SPI 没有给它专门 accessor（如 `getStaticPartitionSpec()`），而是塞进命名为通用容器的 `getWriteContext(): Map`，并在 javadoc 里把承诺扩大为 "static partition spec, write path, and other

误导方向一：新连接器作者读 ConnectorWriteHandle.java:47-51（及类级 :31-34）的 javadoc，会以为可往 writeContext 放 write path 或自定义 key 并期待被填充 / 透传，但引擎侧（PluginDrivenTableSink.java:164-169）永远只写静态分区 spec，其它 key 恒空。 +- 误导方向二：阅读 `handle.getWriteContext()`（如 MaxComputeWritePlanProvider.java:100）者若按字面 "free-form context" 理解，可能误写多余的防御 / 过滤逻辑。 +- 文档与实现不一致会误导维护者，但不会让任何查询 / 写入产生错误数据。 + +**修复方案**（纯重命名 / 收窄语义的表层改动，不改行为）： + +1. 最小改（首选，贴合 Rule 3 surgical）：仅修正 javadoc，把 ConnectorWriteHandle.java **:47-51 与 :31-34 两处**的描述都收窄为 "the INSERT/OVERWRITE static partition spec as a col -> val map"，删掉 write path / other keys 的虚假承诺。**注意 verify 指出 stage-1 只提 :47-51 会漏改类级 :31-34，两处必须同改否则误导仍在。** +2. 更彻底：把方法 / 字段重命名为 `getStaticPartitionSpec()`（与生产者 `PluginDrivenInsertCommandContext.getStaticPartitionSpec`、消费者本地变量 `staticPartitionSpec` 对齐），同步改 3 个 plan provider（Iceberg/Hive/MaxCompute）+ PluginDrivenTableSink + 相关单测；并同步 `IcebergWriteContext.java:36` 按 getWriteContext 命名的注释引用（stage-1 修复点未含，属遗漏但极次要）。 + +当前无功能风险，不阻塞；建议先取方案 1。 + +--- + +## #8 ConnectorTransaction 私有方法泄漏 + +**核实结论**：**CONFIRMED**，置信度 high。两阶段一致（verify.agrees=true），但**最终以 verify 为准并采纳其重要补充**：verify 认可 stage-1 全部事实断言，但指出 stage-1「问题仅限这三个方法、全在 ConnectorTransaction」不完整——odps write-block 语义实为**双接口泄漏**，同时污染了 fe-core 的 `org.apache.doris.transaction.Transaction`。 + +**原报告主张**：通用事务接口被两个连接器塑形：`allocateWriteBlockRange(writeSessionId, count)` 是纯 odps write-session 语义（其它连接器 default 返 false/throw），`registerRewriteSourceFiles(Set)`/`getRewriteAddedDataFilesCount()` 是 iceberg-compaction 专属（default throw）；txn-id 粒度本身 OK。 + +**核实过程**（读了当前以下 file:line）： + +- 通用 SPI 接口 `ConnectorTransaction`（fe-connector-api/.../handle/ConnectorTransaction.java）确实携带三个 source-specific 方法，均带 default： + 1. `supportsWriteBlockAllocation()` default false（:78-80）+ `allocateWriteBlockRange(String, long)` default `throw "write block allocation not supported"`（:94-96）；javadoc（:73-77）明写 "e.g. maxcompute"。 + 2. `registerRewriteSourceFiles(Set)` default throw（:142-144），javadoc（:131-141）标 "Compaction rewrite (rewrite_data_files)"。 + 3. `getRewriteAddedDataFilesCount()` default throw（:154-156），javadoc（:146-153）标 compaction rewrite。 +- 唯一 override（grep 全仓确认无第三个）：MaxComputeConnectorTransaction.java:128-130 返 true、:132-160 实现 block_id 分配（count>0 校验、writeSessionId equals 校验、CAS nextBlockId、maxBlockCount 上限——纯 odps write-session 语义）；IcebergConnectorTransaction.java:365-376 `registerRewriteSourceFiles`（派生 iceberg DataFile）、:1175 `getRewriteAddedDataFilesCount`。 +- 调用侧：FrontendServiceImpl.java:3885-3893（getMaxComputeBlockIdRange RPC，先 `supportsWriteBlockAllocation()` 门控再 `allocateWriteBlockRange`）；ConnectorRewriteDriver.java:151/167（rewrite_data_files 驱动，静态类型 `connectorTx=ConnectorTransaction`）；PluginDrivenTransactionManager.java:175-185 委派 wrapper。 +- **verify 额外核对（stage-1 未覆盖，关键）**：fe-core 的 `org.apache.doris.transaction.Transaction` 本身也带 `supportsWriteBlockAllocation()`（Transaction.java:45-47 default false）与 `allocateWriteBlockRange`（:60-62 default throw）。FrontendServiceImpl:3885 的静态类型正是该 fe-core `Transaction`，实现者为 `PluginDrivenTransactionManager$PluginDrivenTransaction`（委派 connectorTx）；`JdbcTransaction` 等其它实现者当前**白继承**这两个 odps 默认方法。iceberg 那对 rewrite 方法则**只**泄漏在 connector-api ConnectorTransaction，未污染 fe-core Transaction（ConnectorRewriteDriver 直接持 connectorTx 调用）。 + +**背景**：`ConnectorTransaction` 应只承载所有连接器都需要的事务契约（getTransactionId/commit/rollback/close/addCommitData/getUpdateCnt 等）。但它额外带了三个只服务单一连接器的方法，以 default 塞进通用接口。且写块分配这对方法还额外挂在 fe-core 通用接口 `Transaction` 上。 + +**影响（具体示例）**：设计层 SPI 抽象错配（abstraction leak），非运行期 correctness bug——各连接器要么 override、要么被能力位 / default 正确兜住。 + +- 示例 1（不出错但语义耦合）：对一张 hive 表跑 INSERT，其事务从不实现 allocateWriteBlockRange，BE 写路径也不会对 hive 发 block 分配回调（`supportsWriteBlockAllocation` 返 false）；即便误调也只抛 "write block allocation not supported"。行为正确，但通用接口凭空多了 odps 概念。 +- 示例 2：对一张 iceberg 表跑 `CALL rewrite_data_files(...)`，ConnectorRewriteDriver.java:151/167 调这两个方法，仅 iceberg 能应答；若哪天让 paimon/hive 走同一 driver 而未 override，会在**运行期**撞 `UnsupportedOperationException` 而非编译期被拦——default-throw 把「未实现」从类型系统挪到运行期。 +- 架构代价：(1) 每个新连接器作者面对通用接口时看到三个与自己无关的 odps/iceberg 专属方法；(2) fe-core 通用契约被两个具体连接器塑形，违背 connector-agnostic 目标；(3) 按本仓库铁律（MEMORY: fe-core-source-isolation-iron-rules，fe-core 源须 connector-agnostic），把 odps 专属的 `allocateWriteBlockRange` 放到 fe-core `Transaction` SPI 上，**性质上比放在插件侧 connector-api 更违规**——这是这条发现里更该点名的一面。 + +**修复方案**（把 source-specific 语义下沉到窄 opt-in 能力接口，与本仓库既有 `supports*()` 能力 opt-in 范式一致）： + +- 写块分配：新增 `WriteBlockAllocatingTransaction`（含 `allocateWriteBlockRange`），MaxComputeConnectorTransaction 实现。**关键修正（采纳 verify）**：FrontendServiceImpl.java:3885 的调用点静态类型是 **fe-core `Transaction`**（非 ConnectorTransaction），故收敛必须在 **fe-core `Transaction` 这一层**（或其 `PluginDrivenTransaction` 委派 wrapper）一并做——不能只在 connector-api 侧新增窄接口，否则 fe-core `Transaction` 上的 odps 默认方法与 `JdbcTransaction` 等的白继承仍在，泄漏未消。 +- 压实重写：新增 `RewriteCapableTransaction`（含 `registerRewriteSourceFiles` + `getRewriteAddedDataFilesCount`），IcebergConnectorTransaction 实现；ConnectorRewriteDriver.java:151/167 先窄接口 `instanceof` 断言再调，把「不支持」从运行期 throw 提前为类型不匹配。此对只需在 connector-api 侧处理（未污染 fe-core）。 + +txn-id 粒度本身正确（getTransactionId/commit/rollback/close/addCommitData 是真通用契约），default 兜底无 correctness 缺陷，javadoc 已文档化这些方法的连接器专属性（属「有意但已记录的泄漏」），下沉为窄接口是自然收敛方向，属整洁度改进而非缺陷修复。 + +--- + +## #9 ConnectorBucketSpec 表分布 vs per-field bucket + +**核实结论**：**CONFIRMED**，置信度

PARTITION BY LIST (bucket(16, id)) ...`）完全正常——`convertTransformField` 转成 `ConnectorPartitionField(transform="bucket", args=[16])`，`buildPartitionSpec` 再转成 iceberg `builder.bucket(id, 16)`，建出的 partition spec 正确。 +- 潜伏风险 1（静默吞用户意图）：若用户对 iceberg 外表写 `DISTRIBUTED BY HASH(col) BUCKETS N`（Doris 表级分布语法），convertBucket 会产出 `algorithm="doris_default"` 的 bucketSpec，而 iceberg.createTable 完全忽略 `getBucketSpec()` → 该子句被**静默丢弃**（既不报错也不生效）。因 iceberg 本不用表级 hash 分布，危害有限。 +- 潜伏风险 2（文档陷阱）：javadoc（:31）声称 "iceberg_bucket" 是合法算法值，后续开发者若据此在 convertBucket 加 iceberg 分支发 "iceberg_bucket" 并期望 iceberg.createTable 去 `getBucketSpec()` 消费，会发现根本没有接线端——白写。这正是「类别错误」埋的雷。 + +**修复方案**（均轻量、非功能性）： + +- 首选（消除误导，最贴合外科手术式改动）：删除或改写 ConnectorBucketSpec.java:31 那行 javadoc，去掉从不存在的 "iceberg_bucket" 算法值，明确注明本 SPI 只承载表级 hash/random 分布，iceberg 的 per-field bucket 走 `ConnectorPartitionField` transform 路径。 +- 可选（防静默吞子句）：若担心风险 1，可在 iceberg.createTable 里对非空 `getBucketSpec()` fail-loud（抛 DorisConnectorException 提示改用 `PARTITION BY bucket(N,col)`），对齐 hive 连接器 fail-loud 既有范式（HiveConnectorMetadata.java:1646 附近）。但需先确认 legacy iceberg 建表对 `DISTRIBUTED BY` 的原有行为再决定，避免行为回归。 + +因不产生错误结果，建议按 S 级低优先处理，首选仅修文档。 + +--- +

fe-core-source-isolation-iron-rules、catalog-spi-plugindriven-no-source-specific-code）直接呼应。 + +**与其他类别的关联**：#8 中 write-block 泄漏到 fe-core `org.apache.doris.transaction.Transaction`，是本类别里唯一触碰 fe-core 源隔离铁律的一面，性质比纯插件侧泄漏更重，与「fe-core 通用契约不得被 source-specific 代码污染」的架构主线（其它类别的 PluginDrivenScanNode connector-agnostic 要求同源）相通；#7/#9 的「javadoc 承诺 vs 实际接线」错配则属纯文档层收敛，可在同一轮 SPI 清理中一并处理。 diff --git

`HudiForceJniTest` 锁定。去掉伪回归后仅剩纯架构观察（多连接器各自实现 reader-type 决策 + 3 种线上编码 + thrift 不对称），因三种湖格式删除/读语义本质不同，属 nit 而非 bug。 + - #28 是**已修陈旧债**（STALE_FIXED）——detect-and-delegate 已在 #65473 与「hms 进 SPI_READY_TYPES」原子一起落地，报告预测的失效模式从未真正出现。报告本身诚实标注为「分阶段债」，判断质量高。 +- **共性根因**：两条发现都源于「报告成文时间点」与「当前工作树」之间的代码演进（尤其 2026-07-20 前后的 #65473 与 hudi force_jni honor 实现）。这类发现应始终以当前工作树为基线复核，而非轻信 survey 描述。 +- **与其他类别的关联**：#28 的 sibling 委派机制（`resolveSiblingOwner` + child-first classloader）与「iceberg-on-HMS 委派需补 e2e」（见 MEMORY 中 `hms-iceberg-delegation-needs-e2e`）相关——当前休眠单测只证路由，异构 HMS 目录的 INSERT/DELETE/MERGE/ALTER/EXECUTE e2e 回归仍待统一补齐；这是后续工作项，而非本发现的功能缺陷。#27 若真要收敛统一 ReaderType 枚举，会碰「fe-core 只出不进 / 禁 scaffolding」铁律，应作为独立设计任务而非挂在本发现名下。 diff --git

Literal / 谓词粒度(#1, #18, #23) + +**#1 `ConnectorLiteral` 无 typed `getStringValue()`(🔴 根因)**——SPI 只揣裸 `Object` + `toString()==value.toString()`,逼每个连接器自己从 Java 值重推 canonical string。`LocalDateTime.toString()` 出 ISO `T`(`2021-01-01T00:00:00`)、`Boolean` 出 `true`/`false`、`BigDecimal` 出科学计数——都不等于 Doris/Hive canonical 形式。**同一缺口,divergent fill**:`HiveConnectorMetadata.extractLiteralValue:381` 用 `String.valueOf(val)` 推错;`IcebergPredicateConverter:310+` 手写 `dorisDateTimeString()` + bool `'1'/'0'` 推对。更讽刺:canonical string 在 `ExprToConnectorExpressionConverter:305` 边界拿得到,却为 datetime 丢弃(存裸 `LocalDateTime`)。这是 hudi/paimon/hive 一系列分区匹配 bug 的**共同 SPI 根因**。 + +### B. Schema / 列身份粒度(#2, #10, #11, #12, #19, #22) + +**#2 `getColumnHandles` 无 snapshot 参数(🔴)**——从 `table.schema()`(latest)建,handle 按**名字** key(揣的 fieldId 对身份判等是死的)。`buildColumnHandles` 做 `allHandles.get(slot.getColumn().getName())`,miss 就静默丢列。time-travel 跨 RENAME:query slot 带 pin 的旧名,latest map 里没有 → 列被丢出 `columns`。**iceberg 只因在 pin 下忽略 `columns`、从完整 pinned schema 重建 field-id dict 才幸免**(`IcebergScanPlanProvider:1268` 注释明说这防"BE StructNode DCHECK crash");**paimon native projection 按名消费 `columns`,无此 fallback → 更脆**。这是 P6-1 那个 crash 的 schema-grain 兄弟。 + +**#10 列 DEFAULT**:iceberg `parseSchema` 硬编码 `null`,从不读 `initialDefault()/writeDefault()`;且 `ConnectorColumn` 单 `defaultValue` 槽,连 iceberg v3 的 initial(填历史行)vs write(新写)两 default 都塌成一个。(P0 转换器传 null 已在 tip 修) + +**#11 paimon CREATE per-列类型参数**:CHAR/VARCHAR 长度塌成 `VarChar(MAX)`、DATETIME scale 塌成默认微秒;decimal 精度保留。 + +### C. 分区粒度(#4, #13, #14, #20) + +**#4 Hive 分区值不 unescape(🔴)**——`parsePartitionName` 取 `part.substring(eq+1)` 无 `FileUtils.unescapePathName`,legacy `HiveUtil:190` 有。含 `/ 空格 : % 非ASCII` 的分区值 → escaped actualValue 永不等于 unescaped 谓词 → 分区剪光丢行。和 hudi P3 同族(hive 副本)。 + +**#14 `listPartitionValues` 无类型**:paimon 返回原始 `partition.spec()` map(DATE=epoch-day `19723`、NULL=未归一 `__DEFAULT_PARTITION__`),与 `getPartitionName()`(格式化日期、归一 null)不一致;iceberg 无 override。休眠(TVF 还走 legacy HMS,零 fe-core 消费者)。 + +### D.

读 pinned old → stats/scan 偏斜(仅估计,不错结果)。**schema 已原子 pin,stats 没有**——P6-1 的 stats-grain 兄弟。 + +**#17 MVCC branch ref 定点 vs 移动(🟠)**——`ConnectorMvccSnapshot` 是定点(snapshotId+schemaId),但 branch 是**移动引用**(head 会进);`applySnapshot` 路由到 `scan.useRef(name)`,scan 跟 branch head(忽略 pin 的 snapshotId),而 schema/stats 定点。plan→scan 之间对 branch 的 schema-changing commit → BE 用旧 schemaId 读新 schema 数据 → 列错配/错行/崩溃。破了 pin 的"query 内一致版本"契约(legacy-parity 机制,但 SPI 把这个定点-移动分裂固化了)。 + +**#25 `ConnectorMvccSnapshot` 无 equals/hashCode**——4 个 MVCC/stats 兄弟类(Partition/View/TimeTravelSpec/TableStatistics)都定义了 equals+hashCode,唯它没有 → 不能按 (table,version) value-key。和 P6-2(version-blind context pin)同源。显式 time-travel 各 relation 各带 pin 作方法参数,故无确诊塌陷——shape smell。 + +### F. 写 / 事务粒度(#7, #8) + +**#8 `ConnectorTransaction` 私有方法泄漏(🟠)**——通用事务接口被两个连接器塑形:`allocateWriteBlockRange(writeSessionId, count)` 是纯 odps write-session 语义(其他连接器 default 返

**给读路径 SPI 补 snapshot 参数(杀 #2/#15/#22)**:`getColumnHandles(session, handle, snapshot)`、`getTableStatistics(session, handle, snapshot)`、谓词转换用 pinned schema。让 schema/stats/handle 和 scan 用**同一个 pin**,消除所有 time-travel 偏斜(而不是靠 iceberg 各自绕过)。 + +3. **`ConnectorScanRange` 补 `getCompressType()` 槽(杀 #6)**——per-file 压缩编码,P7 hive cutover 前必需(否则 hadoop block-lz4 等静默解码失败)。 + +4. **强制 per-split 语义 or 兜底(收 #3 及同类)**:要么 javadoc 明确 `getFileFormat()` 必须 per-file、加校验;要么 BE 侧在 range 无明确 format 时按**文件后缀**兜底(iceberg/native paimon 已是真格式,只救 JNI/COUNT 塌陷)。 + +5. **清理 vestigial 通用槽(治 #21/#9/模式 A)**:要么把 `ConnectorDeleteFile` 建模到能真用的粒度(content/seq/bounds/fieldId),要么删掉零调用者的 `getDeleteFiles()` / `iceberg_bucket` 值,免得下一个连接器信任一个 iceberg 悄悄忽略的槽。 + +6. **MVCC 值类型补齐(治 #16/#24/#25)**:`getNewestUpdateTimeMillis` 改名 `getNewestUpdateMarker`(或边界归一到 millis);`ConnectorMvccSnapshot` 加 equals/hashCode 以支持 (table,version) value-key(顺带对齐 P6-2)。 + +7. **收连接器专属方法进 facet(治 #8/#7)**:odps block-allocation、iceberg-compaction rewrite、writeContext 的静态分区语义——从通用 `ConnectorTransaction`/`ConnectorWriteHandle` 移进可选 facet 接口(像 `getProcedureOps()` 那样能力发现),别堆根接口。 + +**一句话**:SPI 的骨架是对的(iceberg 读侧证明了),问题是**反复在表级建模细粒度概念,靠 iceberg 各自绕过而非 SPI 统一保证**。三条根因级修法(Literal typed string、读路径 snapshot 参数、compress 槽)+ 清理 vestigial 槽,能把这份清单从 26 条压到个位数,并且让 P7 hive / 下一个连接器不必重新踩 paimon 已经踩过的坑。

iceberg 的编译/依赖已彻底清零（Batch 1–3）；Batch 4 删净 dynamodb/logs/bce 三个死依赖。**T5.1 有重大定性纠正**：这簇不是"live 待 SPI 迁移"，而是**已废弃/死功能**，正解是**瘦身成持久化空壳**（用户签字），非 SPI 迁移（详见进度日志 + T5.1）。**T5.2 又是一次定性误判（这次误判的是"活代码"）**：`catalog/authorizer/ranger/hive/` 不是"hive 数据源专有代码"，而是**通用的外部-catalog Ranger 授权器**——名字里的 "hive" 指 **Apache Ranger 内置的 "hive" 服务定义模型**（库/表/列/udf），非 Doris hive 连接器；9 文件零 hive/HMS

`Column.ICEBERG_ROWID_COL`(`__DORIS_ICEBERG_ROWID_COL__`)+position-delete 四元组 struct**（fe-core ~12 处 string-match）。Trino 对照：引擎自持通用 MERGE，连接器只贡献 rowId

`TIceberg*`/`TDataSinkType.ICEBERG_*_SINK`/`MERGE_PARTITIONED`、`Column.ICEBERG_ROWID_COL`、`iceberg_*` 标签、branch-label 值全未动）；EXPLAIN 无影响（无 `.out` 钉这些节点名，常规 EXPLAIN DELETE/MERGE 渲染通用

+ 连接器声明的表属性/能力），而非引擎的分析器。 + +**目标**：把这些按源 DDL 校验从 fe-core 下沉到 iceberg / paimon / hive 连接器；fe-core 侧只减不增（除新增一个**连接器无关**的能力位枚举成员）。 + +**为什么这条路可行（关键前置事实，均已核验）**： +- 送进连接器的建表请求 `ConnectorCreateTableRequest` **已携带全部所需字段**：每列 `nullable/isKey/type`（`ConnectorColumn`）、`bucketSpec`（= `DISTRIBUTE BY` 存在性）、`sortOrder`（= `ORDER BY` 写序子句）、`partitionSpec`（`LIST/RANGE/IDENTITY/TRANSFORM` + 字段 + `hasExplicitPartitionValues`）。→ 下沉**无须给 fe-core 加新管道**。 +- **已有范式**：`MaxComputeConnectorMetadata.createTable` 在方法开头调 `validateColumns(...)`（`fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java:377`），抛 `DorisConnectorException`（unchecked），由 `PluginDrivenExternalCatalog.createTable` 的 `catch

`session.getProperty("allow_partition_column_nullable", Boolean.class)`（默认 `true`）。 +- 连接器能力位机制**已存在且 fe-core 已在用**：`ConnectorCapability` 枚举 + `connector.getCapabilities().contains(...)`（`PluginDrivenExternalCatalog` 已用 `SUPPORTS_VIEW`/`SUPPORTS_USER_SESSION` 门控）。 +- **hms→hive 路由已澄清（定性核验）**：对 hive-metastore 目录建表**永远**建普通 hive 表，绝不会经此路径建 iceberg-on-HMS / hudi-on-HMS 表（引擎被 `checkEngineWithCatalog` 锁死成 `hive` + 每目录单连接器 + 兄弟分流不在建表路径，三重保险）。→ 把 hive 校验搬进 hive 连接器**不会误伤**其它表格式。 + +--- + +## 2. 采用的接缝与范式 +

`AnalysisException`；下沉后在**执行期**（连接器 `createTable`）抛 `DorisConnectorException`，稍晚，且命中 `IF NOT EXISTS` 已存在表时短路跳过——与 MaxCompute `validateColumns` 现状一致，已是既定放宽。 + +--- + +## 3. 逐项设计 + +### 3.1 paimon —— 拒绝 `DISTRIBUTE BY` + +- **搬出（fe-core）**：`CreateTableInfo.validate()` 的 paimon `else if`（`engineName==PAIMON && distribution != null` → 抛错）。⚠️ 这是 iceberg/paimon 的 `if / else-if` 链，**只删 paimon 这一臂**，iceberg 臂由 3.2 处理。 +- **搬入（连接器）**：`PaimonConnectorMetadata.createTable`（`fe-connector-paimon`）**第一句**（在 `PaimonSchemaBuilder.build` 之前、`executeAuthenticated` try 之外——try 的 catch 会把异常重写成 "Failed to create Paimon table ..."，会破坏文案）：`if (request.getBucketSpec() != null) throw new DorisConnectorException(<原文案>)`。 +- **文案**（字节保持）：`Paimon doesn't support 'DISTRIBUTE BY', and you can use 'bucket(num, column)' in 'PARTITIONED BY'.` +- **必要性**：`PaimonSchemaBuilder` **故意忽略** `bucketSpec`（源码注释在案）；若只删 fe-core 而不加连接器拒绝，`DISTRIBUTE BY` 会**静默成功**（回退）。 +- **信号保真**：`request.getBucketSpec()!=null ⇔ info.getDistribution()!=null ⇔ 用户写了 DISTRIBUTE BY`（自动默认分布仅 OLAP 引擎触发，不会污染 paimon）。 + +### 3.2 iceberg —— 拒绝 `DISTRIBUTE BY` + 排序列校验 + +- **搬出（fe-core）**： + -

`IcebergSchemaBuilder.buildSchema` 之前）： + 1. `if (request.getBucketSpec() != null) throw ...`（拒绝 DISTRIBUTE BY）。 + 2. 排序列校验：遍历 `request.getSortOrder()`，对每个 `ConnectorSortField.getColumnName()`

`Duplicate sort order column: `（e2e 断言 `Duplicate sort order column`） +- **注意**：今天 iceberg 连接器**信任** fe-core（`buildSortOrder` 只映射不校验）；下沉后必须**真正**对请求列校验。排序校验须在 `buildSchema` 之前，否则 metric 类型列会先在 schema 构建时因类型映射失败报另一条错（文案漂移）。大小写不敏感与现有 `resolveColumnName` 行为一致。 + +### 3.3 排序反向拦截（"只有 iceberg 支持排序"）→ 连接器能力位 + +- **搬出（fe-core）**：`validate()` 中 `if (sortOrderFields present) { if

order (ORDER BY) is not supported for engine ''`），不点名 iceberg。 + - **放置与全引擎奇偶保真**（实现已采**首选**）：现状的反向拦截不仅覆盖 SPI 引擎，也覆盖 legacy 内部目录引擎（mysql/broker/es）。**已落地**：在 `CreateTableInfo.validate()`（分析期）按目标目录的连接器能力位做**通用**门控——`catalog instanceof PluginDrivenExternalCatalog && catalog.getConnector().getCapabilities().contains(SUPPORTS_SORT_ORDER)`；不满足即抛 `Sort order (ORDER BY) is not supported for engine: `。SPI iceberg 有能力→放行（列级校验由 iceberg 连接器 `createTable` 做）；SPI 其它→拒绝；legacy 内部目录引擎（非 PluginDriven）→拒绝，奇偶保真。仅当建表带 `sortOrder` 时才触发 `getConnector()`（罕见，仅 iceberg 带 ORDER BY 的建表会在分析期 init 连接器，与随后执行期 init 相差毫秒，可接受），不点名数据源。 + +### 3.4 hive —— 拒绝 `NOT NULL` 列 + +- **搬出（fe-core）**：`validate()` 中 `for (columnDef) if (!columnDef.isNullable() && engineName==HIVE) throw

主源码对数据源库的编译期依赖**几乎清零**——唯一残留是死代码 `StatisticsUtil.getIcebergColumnStats`。但 **不能立即删** iceberg 依赖，因为还有 **5 个 iceberg 相关测试类**（连接器 metastore/property 解析测试）留在 fe-core 里，把 `iceberg-core`/`iceberg-aws` 钉在编译类路径上。 + +**可直接删（低风险）**：`lakesoul-io-java`、`scala-library`（均 provided、废弃 lakesoul、零引用）。 + +**删除需先动代码**：整个 iceberg-AWS 依赖簇（`iceberg-core` / `iceberg-aws` / `glue` / `s3tables` / `s3-tables-catalog-for-iceberg` / `aws-json-protocol`）应作为**一个批次**移除，前置条件是把 5 个 iceberg 测试类迁到连接器模块 + 删死方法。 + +**注释纠错（保留但注释是错的）**：`kryo-shaded` 注释写"for hudi catalog"，实际消费者是 `WorkloadSchedPolicy`；`avro`/`parquet-avro` 注释写"For Iceberg"，实际是 fe-core 的 parquet reader 在用。 + +**必须保留（S3 文件系统/凭证/UDF 需要，非数据源用途）**：`s3-transfer-manager`、`sts`、`url-connection-client`、`protocol-core`、`sdk-core`、`kryo-shaded`、`hive-exec(runtime)`、`commons-lang(runtime)`。 + +**代码层面**：fe-core 里仍有相当量的数据源特有代码，分两类—— +- **真·死代码**（可直接删）：iceberg 的 `StatisticsUtil.getIcebergColumnStats`、`UnboundIcebergTableSink` 及其分支、`IcebergInsertCommandContext`；hive 的 `HiveInsertCommandContext`。 +- **仍 LIVE 的数据源特有逻辑**（需迁移设计，不能简单删）：**iceberg 行级 DML 一整块（~15 个文件）**、hudi 的 `hudi_meta` TVF（3 文件）、legacy `engine=hive` broker-load 簇、`ranger-hive` 授权包、es 废弃内置引擎兼容桩、以及若干 `CreateTableInfo`/`Env`/`Coordinator` 里的按源硬编码分支。 +- **trino**：已完全迁移干净，fe-core 里 0 个 io.trino 引用、0 个 trino-connector 目录类。 + +--- + +## Part A — pom.xml 依赖可移除性分析 + +### A.1 判定口径 + +- **REMOVE**：fe-core 无编译引用、无运行时/反射/ServiceLoader 需要，且没有任何"保留项"（S3 文件系统 / 凭证签发 / parquet / UDF 引擎）传递依赖它。可直接删 ``。 +- **KEEP**：fe-core 因**非数据源**原因真需要它，或某个保留项需要它。 +- **REMOVE_AFTER_CODE_CHANGE**：只有一小块死代码 / 放错位置的代码把它吊着，先动那块代码即可转 REMOVE。 + +一条铁律：某依赖注释写"给 iceberg 用"**并不**意味着可删——必须确认 `hadoop-aws` / S3 文件系统 / 凭证代码（都保留）没有一并拉它（双用途）。 + +### A.2 iceberg / AWS-iceberg 依赖簇 —— 作为**一个批次**移除 + +| artifact | pom 行 | scope | 判定 | 依据 | +|---|---|---|---|---| +| `org.apache.iceberg:iceberg-core` | 576–580 | compile | **REMOVE_AFTER_CODE_CHANGE** | 主源码唯一消费者 `StatisticsUtil.getIcebergColumnStats`（死代码，全 `fe/` 零调用）用的是 iceberg-**api** 类；真正把 iceberg-**core** 钉住的是 **5 个测试类**（见下）。删死方法 + 迁走测试后可删；在 iceberg-aws 未删前它仍作为其 runtime 传递依赖存在。 | +| `org.apache.iceberg:iceberg-aws` | 581–585 | compile | **REMOVE_AFTER_CODE_CHANGE** | 唯一消费者是 2 个 `@Disabled` 测试 `AWSTest.java`、`IcebergGlueRestCatalogTest.java`（直接 `new GlueCatalog()` / `CatalogUtil.buildIcebergCatalog`）；主源码 0 引用。连接器 `fe-connector-iceberg/pom.xml:149` 自带 iceberg-aws，不依赖 fe-core 供给。 | +| `software.amazon.awssdk:glue` | 587–596 | compile | **REMOVE** | fe-core 主+测源码 0 个 `services.glue.*` 引用；在 JDK17 上做过**实证编译**：移除 glue jar 后 mirror `AWSTest.testGlueCatalog()` 仍编译通过（arity 不匹配的重载 + private 字段不触发 javac 符号解析）。生产 Glue 走插件（`GsonUtils.java:393` 的 `IcebergGlueExternalCatalog` 别名）。`hadoop-aws`/`s3-transfer-manager`/`iceberg-aws` 均不拉 glue。 | +| `software.amazon.awssdk:s3tables` | 765–768 | compile | **REMOVE** | 冗余：BOM（2.29.52）+ `s3-tables-catalog-for-iceberg` 已在 runtime scope 传递供给；fe-core 0 编译引用（`S3TablesTest` import 的是 `software.amazon.s3tables.*` 而非 `awssdk.services.s3tables`）。S3 文件系统用 `awssdk:s3`，不碰 s3tables。可**立即**删。 | +| `software.amazon.s3tables:s3-tables-catalog-for-iceberg` | 769–773 | compile | **REMOVE_AFTER_CODE_CHANGE** | 唯一编译消费者是 `datasource/s3tables/S3TablesTest.java:27`（`import software.amazon.s3tables.iceberg.S3TablesCatalog`）。构建 `-DskipTests` 仍会**编译**测试→不先删该测试则 `cannot find symbol`。下游 `fe-connector-iceberg`、`be-java-extensions` 各自声明，不依赖 fe-core。 | +| `software.amazon.awssdk:aws-json-protocol` | 619–622 | compile | **REMOVE（随本批一起）** | fe-core 0 引用。json 协议的唯一消费者是数据源客户端 glue / s3tables / iceberg-aws（各自 pom 已 compile 声明同版本 2.29.52）。保留项里 `sts`=query 协议、`s3`=xml 协议、`hadoop-aws`=0；故它应与 iceberg 簇**一起**离开，不要单独删。 | + +> **关键纠错（完备性 critic 发现，已本人二次核验）**：把 iceberg 依赖钉在编译类路径上的**不是主源码**，而是 5 个仍留在 fe-core 的测试类——它们本质是连接器 metastore/property 解析测试，应随迁移搬到 `fe-connector-iceberg`： +> - `src/test/java/org/apache/doris/datasource/property/metastore/IcebergUnityCatalogRestCatalogTest.java`（iceberg-core + `rest.*`） +> - `.../metastore/IcebergGlueRestCatalogTest.java`（iceberg-core + **iceberg-aws** `AwsClientProperties`/`S3FileIOProperties`） +> - `.../metastore/AWSTest.java`（**iceberg-aws** `glue.GlueCatalog`） +> - `.../metastore/IcebergDlfRestCatalogTest.java`（iceberg-core） +> - `.../datasource/s3tables/S3TablesTest.java`（iceberg-core + s3-tables-catalog） +> +> 因此 iceberg 依赖不是"主源码删干净了就能删"，而是**门槛在这 5 个测试类的归属**。 + +### A.3 AWS SDK 依赖簇 —— 双用途，**保留** + +这些是 AWS SDK v2 的共享底座，被**保留**的 S3 对象存储文件系统 + STS AssumeRole 凭证签发所需，与 iceberg 无关： + +| artifact | 判定 | 保留原因（非数据源消费者） | +|---|---|---| +| `software.amazon.awssdk:s3-transfer-manager` | **KEEP** | `hadoop-aws 3.4.2` 的 `S3AFileSystem` 硬引用 `transfer.s3.S3TransferManager`（jar 内 78 处 `transfer/*`）；父 pom 排除了 hadoop-aws 的 `awssdk:bundle`，此独立 jar 是唯一供给源。 | +| `software.amazon.awssdk:sts` | **KEEP** | `S3Properties.java:44-45`、`S3Util.java:51-52` 直接 import `StsClient` + `StsAssumeRoleCredentialsProvider`（对象存储凭证路径）。 | +| `software.amazon.awssdk:url-connection-client` | **KEEP** | `S3Util.java:47` 编译引用 + `DorisFE.java:241-242` 启动时 `System.setProperty("...http.service.impl", UrlConnectionSdkHttpService)` 解决"Multiple HTTP implementations"，对**所有** AWS SDK v2 客户端（含保留的 S3/STS）生效。 | +| `software.amazon.awssdk:protocol-core` | **KEEP** | `sts` / `s3` / `s3-transfer-manager` 的 2.29.52 pom 都直接依赖它（共享 marshaller 基座）。 | +| `software.amazon.awssdk:sdk-core` | **KEEP** | `S3Util.java:43-46` 引用 `ClientOverrideConfiguration`/`RetryPolicy` 等；且 fe-core **vendored** 了 `software/amazon/awssdk/core/client/builder/SdkDefaultClientBuilder.java`（引 ~30 个 sdk-core 类型）。 | + +### A.4 avro / parquet-avro —— 注释误导，实为 parquet reader 所用 + +| artifact | pom 行 | 判定 | 依据 | +|---|---|---|---| +| `org.apache.parquet:parquet-avro` | 633–636 | **REMOVE_AFTER_CODE_CHANGE** | fe-core 主+测 0 个 `org.apache.parquet.avro.*` 引用。真正的 parquet 消费者是 LIVE 非数据源代码 `common/parquet/ParquetReader.java`（`BrokerInputFile`/`LocalInputFile`），被 `httpv2/restv2/ImportAction.java:160`（HTTP 导入抽样）调用，只用 `org.apache.parquet.{io,column,hadoop,schema}`。**改法**：把 `parquet-avro` 换成 `parquet-hadoop`（+`parquet-column` 兜底）——`parquet-hadoop` 不依赖 avro，保留 ParquetReader 所需全部类，丢掉 avro 桥。 | +| `org.apache.avro:avro` | 627–631 | **REMOVE_AFTER_CODE_CHANGE（且与 iceberg 批耦合）** | fe-core 0 个 `org.apache.avro.*` 引用（`AvroFileFormatProperties*` 是纯属性解析，不 import avro）。但删除受两处传递依赖约束：① `iceberg-core`（compile）的 pom 声明 avro，故须**排在 iceberg 移除之后**才能真正离开编译类路径；② 保留的 UDF 引擎 `hive-exec:core`（runtime）也声明 avro→avro 会**永远**留在 runtime 类路径。净效果：删掉这条"给 iceberg"的显式声明是安全的（版本由 dependencyManagement 兜底），但要与 parquet-avro 的替换 + iceberg 移除**一起排期**，且并不会把 avro 真正逐出 `fe/lib`。 | + +### A.5 kryo-shaded —— 保留，但注释过期需纠正 + +| artifact | pom 行 | 判定 | 依据 | +|---|---|---|---| +| `com.esotericsoftware:kryo-shaded` | 675–679 | **KEEP（改注释）** | 注释 `` **已过期**。fe-core 唯一消费者是 `resource/workloadschedpolicy/WorkloadSchedPolicy.java:32` 的 `import com.esotericsoftware.minlog.Log`（`gsonPostProcess()` 里 `Log.error(...)`，live 非数据源）。`minlog` 由 `kryo-shaded-4.0.2` compile 传递、且是 `Log.class` 的唯一持有者；无其它编译路径供给。删它会破 `WorkloadSchedPolicy` 编译。**建议**：注释改为指向真实消费者（workload scheduling），别当"hudi 清理"删掉。 | + +### A.6 完备性 critic 发现的**额外**依赖（不在原 iceberg/hudi 清单内） + +| artifact | pom 行 | scope | 判定 | 依据（已本人核验） | +|---|---|---|---|---| +| `com.dmetasoul:lakesoul-io-java` | 498 | provided | **REMOVE** | lakesoul 已废弃（`CatalogFactory.java:143` 抛"Lakesoul catalog is no longer supported"）。fe-core 0 个 `com.dmetasoul`/lakesoul 类引用，全是 Gson 兼容重映射字符串。 | +| `org.scala-lang:scala-library` | 570 | provided | **REMOVE** | fe-core 0 个 `import scala.`（lakesoul 陪跑品）。 | +| `org.postgresql:postgresql` | 564 | provided | **REMOVE（先查测试）** | lakesoul 陪跑品，但 `src/test/.../catalog/JdbcResourceTest.java` import 了 `org.postgresql`，provided 在测试类路径上→删前需处理该测试。 | +| `com.baidubce:bce-java-sdk` | 556 | compile | **REMOVE（Batch 4 已删）** | 全 `fe/**/src` 零引用（主+测）、全仓库零 `com.baidubce`/反射/config 加载。BOS 走 S3 兼容路径（`cloud/storage/ObjectInfoAdapter.java` `case BOS`→`S3Properties`；`S3Properties.PROVIDERS` 含 BOS；`SchemaTypeMapper` BOS 已注释掉），原生 SDK 不在 BOS 路径上；fe-filesystem 亦不声明→非"迁移"而是"删"。**删除坑**：bce 是 fe-core 唯一传递带来 `javax.validation:validation-api` 的源，`ExternalMetaIdMgr` 一处装饰性 `@NotNull` 靠它编译（下一行 `Preconditions.checkNotNull(log)` 才是真校验，全 fe 唯一一处 javax.validation 用法）→删该注解而非加依赖（守 fe-core 只减不增）。连带清理孤立的 mqtt（仅 bce 传递）+ validation-api 依赖管理块/属性。 | +| `com.amazonaws:aws-java-sdk-dynamodb` | 371–374 | compile | **REMOVE（Batch 4 已删）** | `dependency:tree` 证其为 fe-core **直接叶子**（零传递消费者）；hadoop-aws 3.4.2 已随 Hadoop 3.4.0 移除 S3Guard（jar 内零 dynamodb 类，仅剩 `S3Guard.class` 一句"不再需要"的警告字符串）；ranger 审计无 DynamoDB destination；全仓库零 `dynamodbv2` 引用/反射/config。（be-java-ext 的 dynamodb 是 v2 `software.amazon.awssdk`，无关。） | +| `com.amazonaws:aws-java-sdk-logs` | 375–378 | compile | **REMOVE（Batch 4 已删）** | 同 dynamodb：直接叶子、零传递消费者。父 pom "only for apache ranger audit" 注释**已过时**——唯一引用 CloudWatch 的 `AmazonCloudWatchAuditDestination` 在 `ranger-plugins-audit`，而 fe-core 只有 `ranger-plugins-common:2.8.0→ranger-audit-core:2.8.0`（仅 File/base destination），`ranger-plugins-audit` 全不在 fe-core 546-jar 类路径上；全仓库零 `amazonaws.services.logs` 引用/config。 | +| `org.apache.kafka:kafka-clients` | 647 | compile | **超范围** | fe main 0 个 `import org.apache.kafka`（routine-load 经 BE thrift，`load/routineload/kafka/*` 是 Doris 类）。非湖仓 catalog，可能独立清理但不在本次数据源计划内。 | + +### A.7 看着像数据源、实为内部用途，**保留** + +| artifact | 判定 | 真实消费者 | +|---|---|---| +| `org.mariadb.jdbc:mariadb-java-client` | **KEEP（内部）** | `httpv2/util/StatementSubmitter.java:68`（`jdbc:mariadb://127.0.0.1` 打 FE 自己的 MySQL 端口）；JDBC 外表 catalog 是动态加载驱动，不靠这条编译依赖。 | +| `org.apache.ranger:ranger-plugins-common` | **KEEP（双用途）** | 既有 hive ranger（数据源），也有 Doris 内表 ranger 授权 `catalog/authorizer/ranger/doris/RangerDorisPlugin.java`（非数据源）→内表侧吊着它。 | +| `com.zaxxer:HikariCP`

ServiceLoader 注册（`ranger-hive`），领着 fe-core 里一个 9 文件的 hive 授权包（`HiveObjectType`/`HiveAccessType`/`RangerHiveResource`）。只 import `org.apache.ranger.*`（非 hive 库），属"源特有行为"违规。这是**授权迁移轴**，独立于连接器 scan 轴。 + + > **⚠️ 2026-07-21 T5.2 执行纠正——本条定性为「确认误判」（T5.1 同款过宽判定，这次误判的是"活代码"）**：`ranger-hive` **不是** hive 数据源专有代码，而是**通用的外部-catalog Ranger 授权器**。名字里的 "hive" 指 **Apache Ranger 内置的 "hive" 服务定义模型**（资源层级：库→表/udf→列；`HiveObjectType`/`HiveAccessType` 就是 Ranger hive 服务定义词汇，含 `SERVICEADMIN`/`TEMPUDFADMIN`），**非** Doris 的 hive/HMS 连接器。硬证：① 9 文件**零** `org.apache.hadoop.hive`/metastore/HMS/`datasource.hive` import（唯一 hadoop import 是审计用 `hadoop.conf.Configuration`），其余全是 `org.apache.ranger.*` + fe-core 鉴权框架类型；②

**中立性**：公共接口里不应该出现只有某一种数据源才成立的概念、名字或行为。 +2. **必要性**：每个方法都应该有真实的调用方；没人调用的方法是负债——它会让新连接器的作者以为"必须实现"。 +3. **单一职责**：一个接口应该只表达一件事。把互不相干的能力塞进同一个接口，会迫使实现者面对一大堆与自己无关的方法。 +4. **契约自洽**：接口文档写的规则，实现必须真的遵守；反过来，实现普遍采用的行为，文档不能写反。 + +--- + +## 二、现状概览 + +| 模块 | 内容 | 调研日（`7ff51a106f0`） | 复核日（`53a753e0a1b`） | +|---|---|---|---| +| `fe-connector-api` | 连接器要实现的业务接口 + 中立数据结构 | 95

仍然成立且升级为三方矛盾，是全文最该先做的一条** | + +--- + +## 四、问题详述 + +### A. 新增连接器仍然必须修改 fe-core + +这是最直接违背目标的一类问题，共 3 处。 + +#### A1. fe-core 里写死了"哪些类型走插件路径"的白名单 + +> **状态（复核 `53a753e0a1b`）：已落地。** `SPI_READY_TYPES` 全仓零命中，白名单由 `23b971a4db9` 整体删除；路由改为先问插件注册表。本节建议的"反向名单"也已经存在：`CatalogFactory.BUILTIN_CATALOG_TYPES = {"lakesoul", "doris", "test"}` 配 `isBuiltinCatalogType`，且那三个内建类型名成为保留字——插件声明它们时在注册期就被拒绝。 + +`fe-core/src/main/java/org/apache/doris/datasource/CatalogFactory.java:56` + +```java +private static final Set SPI_READY_TYPES = + ImmutableSet.of("jdbc", "es", "trino-connector", "max_compute", "paimon", "iceberg", "hms"); +``` + +只有出现在这个集合里的 catalog 类型才会去查找连接器插件（第 110 行）。 +也就是说：即使一个新连接器完整实现了 `ConnectorProvider` 并正确注册到 `META-INF/services`、 +插件包也放进了插件目录，**只要不在这行字符串里加上自己的类型名，`CREATE CATALOG` 就完全不会走插件路径**。 + +**背景**：这个白名单是迁移期的安全阀——迁移过程中同一个类型可能同时存在"老的内建实现"和"新的插件实现"， +白名单保证只有已经验证过的类型才切到新路径。 + +**原因**：它把"这个类型有没有插件"（可以运行时发现）和"这个类型允不允许用插件"（人工决策）混在了一起。 + +**解决方向**：把判断反过来——先问插件注册表"有没有 provider 支持这个类型"，有就走插件路径，没有再走内建分支。 +人工决策改由"是否把插件包放进插件目录"来表达，这本来就是插件机制天然的开关。 +迁移期若仍需保留强制内建的能力，可以改成一个**反向的**小名单（"这些类型即使有插件也强制走内建"）， +迁移完成后直接删掉，而不是每加一个连接器就改一次。 + +#### A2. fe-core 里按 catalog 类型做的两处 switch + +> **状态（复核 `53a753e0a1b`）：仍然成立，且属于已知未决而不是遗漏。** 两处 switch 原样存在（符号未变，行号已漂到 `getEngine()` / `getEngineTableTypeName()` 各自的定义处）。后续有一轮专门中立化了另外两处按类型名匹配的引擎分支（`73d90807eaf`），审到这两处时判定**暂不下沉**——它们只影响对外展示名，不影响功能可达性。 + +`fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenExternalTable.java:1275` 和 `1313` + +两个方法（`getEngine()` 与 `getEngineTableTypeName()`）都是对 catalog 类型字符串做 switch， +把 `"jdbc" / "es" / "iceberg" / "trino-connector" / "max_compute" / "paimon" / "hms"` 分别映射成对外展示的引擎名和表类型名。 +这两个值会出现在 `SHOW TABLE STATUS`、`information_schema.tables`、REST 接口里。 + +**背景**：这是为了兼容——迁移前每种外部表都是一个独立的 Java 类，有各自的展示名； +迁移后它们都变成同一个 `PluginDrivenExternalTable`，如果不 switch 就会统一显示成 `Plugin`，属于用户可见的行为回退。 + +**影响程度**：比 A1 轻。新连接器不加分支也能工作，只是展示名会落到默认值。 +但这仍然是"公共模块里按数据源名字分叉"的写法，与既定的架构原则冲突。 + +**解决方向**：把展示名变成连接器自己声明的东西。最小改动是在 `ConnectorProvider` 上加一个 +`default String getEngineDisplayName() { return getType(); }`，让 fe-core 直接取值； +已有的 7 个连接器各自返回它们的历史名字，switch 整体删除。这样新连接器不写也有合理默认值。 + +#### A3. 能力项是一个封闭枚举 + +`fe-connector-api/.../ConnectorCapability.java` + +`ConnectorCapability` 是一个 13 项的枚举。连接器通过 `Connector.getCapabilities()` 返回自己支持的集合。 +问题是：**任何一个新连接器只要需要一项现有枚举没覆盖的能力，就必须修改 `fe-connector-api`**。 + +这一点比 A1/A2 更微妙，因为"引擎要理解这项能力才能据此改变行为"，所以能力项本身确实需要引擎认识。 +但目前这 13 项中有相当一部分（见下表）本质上是"某个具体连接器的行为开关"，而不是通用能力： + +| 能力项 | 引擎侧真实用途 | 通用性 | +|---|---|---| +| `SUPPORTS_MVCC_SNAPSHOT` | 是否走快照读路径 | 通用 | +| `SUPPORTS_VIEW` | 是否把对象当视图 | 通用 | +| `SUPPORTS_PARTITION_STATS` | `SHOW PARTITIONS` 渲染几列 | 通用 | +| `SUPPORTS_PASSTHROUGH_QUERY` | `query()` 表函数 | 偏 JDBC | +| `SUPPORTS_SHOW_CREATE_DDL` | 是否渲染属性（防止 JDBC 泄漏密码） | 通用，但动机是安全兜底 | +| `SUPPORTS_TOPN_LAZY_MATERIALIZE` / `SUPPORTS_NESTED_COLUMN_PRUNE` | 优化器开关 | 通用（能力协商） | +| `SUPPORTS_METADATA_PRELOAD` | 是否预热元数据 | 通用（纯性能） | +| `SUPPORTS_USER_SESSION` | 是否注入用户凭证、是否绕开共享缓存 | 通用（安全） | +| `SUPPORTS_SORT_ORDER` | `CREATE TABLE ... ORDER BY` 是否被接受 | 通用（语法门禁） | +| `SUPPORTS_COLUMN_AUTO_ANALYZE` / `SUPPORTS_SAMPLE_ANALYZE` | 统计信息采集方式 | 通用 | +| `SUPPORTS_NESTED_COLUMN_SCHEMA_CHANGE` | 嵌套列 DDL 是否被接受 | 通用 | + +**结论**：枚举本身可以保留（引擎必须认识能力项），但需要**明确一条规则并写进枚举的类注释**： +只有"引擎必须据此改变自己行为"的开关才能进这个枚举； +只有连接器自己需要知道的东西一律不进。 +另外，从这些枚举项的注释里可以看出，绝大多数都是在替换迁移前的"按类名判断"逻辑， +所以这个枚举天然带有"历史包袱清单"的性质，值得在迁移收尾时重新审一遍哪些可以合并或删除。 + +#### A4. 另外两个封闭枚举的实际情况 + +- `ConnectorScanRangeType`（4 项）：见 C1，引擎根本不读，属于死接口，删掉即可，不构成扩展障碍。 +- `ConnectorColumnCategory`（3 项）：只有 3 个中立取值（默认 / 合成列 / 生成列），语义清晰，没有扩展压力，可以保留。 + +> **状态（复核 `53a753e0a1b`）**：`ConnectorScanRangeType` 已由 `da60bfadbac` 整族删除（见 C1 状态戳）。`ConnectorColumnCategory` 保持不变。A3 的 `ConnectorCapability` 枚举**仍是 13 项、一项没增没减**，本节结论未受这 44 个提交影响。 + +--- + +### B. 公共接口里混入了源专有语义 + +这类问题的共同表现是：接口的名字或语义只有在某一种数据源下才讲得通， +新连接器的作者读到它们时无法判断"我要不要实现"。 + +下表是逐条核对"某个方法在 8 个连接器里到底谁实现了"得到的结果（只列出真正有问题的）： + +| 接口方法 | 实现者 | 问题性质 | +|---|---|---| +|

| `sanitizeJdbcUrl` | **仍然成立** | +> | `validateAndResolveDriverPath` / `computeDriverChecksum` | 见下方**交叉核对修正**：前者不是 JDBC 专有 | +> | `schemaCacheTtlSecondOverride` | **仍然成立** | + +还有两个偏"默认值不中立"的问题： + +- `ConnectorScanRange.getFileFormat()` 默认返回 `"jni"`（`:67`）。"jni"不是一种文件格式， + 而是 BE 侧的一种读取机制。把格式和机制混在一个字段里，会让新连接器误以为自己必须返回某种文件格式。 +- `ConnectorScanRange.getTableFormatType()` 默认返回 `"plugin_driven"`（`:121`），而注释举的例子是 `"jdbc"`、`"hive"`。 + 这个字符串直接决定 BE 用哪个读取器，属于 FE/BE 之间的约定，却没有任何类型约束。 + +**为什么会变成这样**：这些方法几乎都是迁移过程中"某个连接器需要一个口子"时加上去的。 +加一个 `default` 方法成本极低（不影响其他连接器），于是公共接口逐渐变成了所有连接器需求的并集。 + +**解决方向**（三条，按适用场景选）： + +1. **能中立化的就中立化**。例如 `adjustFileCompressType` 的本质是"连接器有权决定最终压缩类型"， + 把方法名和文档改成中立表述（不再提 Hadoop 和 LZ4）即可； + `HIVE_DEFAULT_PARTITION` 的本质是"连接器自己的空分区哨兵值"，应该由 hive 连接器持有， + 公共层只保留"连接器可以声明哪些值代表 NULL"的中立能力（`ConnectorPartitionInfo` 已经有 `partitionValueNullFlags` 这条更好的路子）。 +2. **纯展示/诊断类的，改成中立的键值对**。`isNativeReadRange` 只服务于 EXPLAIN 的一行文字， + 而 `ConnectorScanPlanProvider.appendExplainInfo` 已经提供了"连接器自己往 EXPLAIN 里追加内容"的通道， + 前者应该被后者吸收掉。`getSerializedTable` 同理——它的内容最终就是进 `nodeProperties` 的一个值，没必要单独开一个方法。 +3. **真正只属于一种数据源的，移到专门的可选接口上**。参考 api 里已有的好做法： + `RewriteCapableTransaction`、`WriteBlockAllocatingConnectorTransaction` 是两个**窄的、可选实现的**接口， + 引擎用 `instanceof` 判断，连接器不实现就等于不支持。 + `executeRestRequest`（REST 透传）、`executeStmt` + `getColumnsFromQuery`（SQL 透传） + 完全可以照这个模式做成 `ConnectorRestPassthrough`、`ConnectorSqlPassthrough` 两个小接口。 + 同理，`ConnectorValidationContext` 里的驱动包相关方法应该拆到一个 JDBC 专用的校验上下文里。 + +> **交叉核对修正 ①（针对解决方向 1 的前半句）：`adjustFileCompressType` 不算中立性违规，这一整条撤销。** +> 它的方法名与默认实现（恒等）本来就是中立的；javadoc 里提 Hadoop 与 LZ4 的那一段，**恰恰是在解释这个钩子为什么必须存在**，末句原文就是"把这个 hadoop 专有事实圈在连接器里，通用节点保持与数据源无关"。它是"通用节点不得出现数据源专有代码"这条规则的**正面示范**，不是违规。把这段说明删掉，只会让下一个维护者不知道这个钩子干什么，进而把 LZ4 重映射写回通用扫描节点。 +> 注意：它出现在 G3 那份 thrift 类型清单里的那一行**依然成立**（入参是 `TFileCompressType`），两者不矛盾——一处讲语义中立性，一处讲类型依赖。 +> +> **交叉核对修正 ②（针对解决方向 1 的后半句）：空分区哨兵不能下沉到 hive 连接器。** +> 三条硬约束：引擎自己的分区路径解析在用它（`FilePartitionUtils`）；引擎渲染 `partition_values()` 表函数那一格也在用它（`MetadataGenerator`）；**非 hive 的 paimon 连接器主动把空分区归一成这个串**。下沉会让 `fe-core` 反过来依赖 hive 插件，直接违反"`fe-core` 只出不进"的纪律。 +> 实际走的是另一条路（`ec24a866d45`）：**原地中立化改名** `HIVE_DEFAULT_PARTITION` → `NULL_PARTITION_NAME`，值一个字节没动，并把引擎侧那份重复定义删掉——调研日 FE 树里有两份同串定义，现在只剩一份。真正下沉的是**只对目录名式分区成立**的那三个归一方法，它们被内联进唯一使用者 hudi（`2ed7da4cb68`），hudi 自己持有私有的 `"\N"`。 +> +> **交叉核对修正 ③（针对上表第 10 行与解决方向 3 的末句）：`validateAndResolveDriverPath` 不是 JDBC 专有，这条建议在调研日就是错的。** +> iceberg 与 paimon 都在用它做 `CREATE CATALOG` 的驱动 URL 安全门（paimon 侧还有单测钉住），照"拆到 JDBC 专用校验上下文"去做会**直接打断这两个连接器**。真正只属于 JDBC 的只有 `computeDriverChecksum`（唯一调用方是 jdbc）。 + +--- + +### C. 无人调用的死接口 + +这些方法/类型仍在公共接口里，但**在整个仓库（排除测试）中找不到引擎侧的调用点**。 +它们的危害不是运行时错误，而是误导：新连接器的作者读到接口时会认真去实现它们。 + +#### C1. 扫描分片类型（`ConnectorScanRangeType` + 两个 getter） + +> **状态（复核 `53a753e0a1b`）：已整族删除**（`da60bfadbac`）。枚举、两个 getter、以及连带发给 BE 的那个死属性键全部消失，全仓零命中；新增的双向断言测试守住"不再有这个键发给 BE"。 +> +> **交叉核对修正**：本节写的"全部 7 个连接器"是 **8 个**——漏了 trino（`TrinoScanRange`）。按"7 个"去删会漏改 trino 而编译失败。另外，两个方法的默认值情况**并不对称**：分片上那个是接口抽象方法、没有默认实现，所以 8 个分片类被迫逐个实现；扫描计划提供者上那个**有默认值** `FILE_SCAN`，只有 hive / es / jdbc 三家做了与默认值等价的多余覆写。 + +- `ConnectorScanPlanProvider.getScanRangeType()`（`:52`），文档写着"引擎据此决定生成哪种 Thrift 扫描分片结构"。 +- `ConnectorScanRange.getRangeType()`（`:43`），同样的说法。 + +实际情况：`fe-core/src/main` 中**没有任何一处读取这两个方法**（只有测试类里的匿名实现）。 +引擎统一走文件扫描分片结构，具体差异由 `populateRangeParams` 由连接器自己填。 +但这两个方法**没有默认实现或者默认值形同虚设**，于是全部 7 个连接器都老老实实实现了 `getRangeType()` +（es / hive / hudi / iceberg / jdbc / maxcompute / paimon），hive、es、jdbc 还额外实现了 `getScanRangeType()`。 + +这是一次纯粹的无效劳动，而且文档是错的。 + +**建议**：删除 `ConnectorScanRangeType` 枚举和这两个方法；如果将来真的需要多种分片结构， +应该由 `ConnectorScanRange` 的具体子类型来表达，而不是一个平行的枚举标签。 + +#### C2. `ConnectorScanPlanProvider.estimateScanRangeCount`（`:432`） + +> **状态（复核 `53a753e0a1b`）：仍然成立，且是 C 段唯一的幸存者。** 44 个提交没有一个碰过它——接口声明仍在 `ConnectorScanPlanProvider`，唯一实现仍是 `JdbcScanPlanProvider`，`fe-core` 仍然零调用。C 段其余六条（C1 / C3 / C4 / C5 / C7，以及 C6 的一半）都已处置，**只有这一条被漏下了**。 + +文档说"引擎可能用它预分配资源或决定扫描并行度"。全仓搜索结果：**只有接口声明和 JDBC 的一个实现，零调用点**。 + +**建议**：删除。真正在用的并行度提示是 `streamingSplitEstimate`（见后文），两者功能重叠。 + +#### C3. `ConnectorTableOps.listPartitionValues`（`:499`） + +> **状态（复核 `53a753e0a1b`）：已删除**（`891709a08e7`）。该提交的正文同时记录了本节指出的文档错误——javadoc 指向 `partition_values()`，实际走的是分区列举那条路。 + +文档说"被 `partition_values()` 表函数和列去重优化使用"。 +实际情况：`partition_values()` 表函数（`fe-core/.../tablefunction/PartitionValuesTableValuedFunction.java`） +走的是分区列 + 分区项那条路，从不调用这个方法。 +但 paimon、maxcompute、hudi 三个连接器都实现了它（并且实现里还要处理列顺序对齐等细节）。 + +**建议**：确认历史上的调用点确实已经迁走后删除；若还有保留价值，必须把文档改成真实用途。 + +#### C4. 连接器属性描述（`ConnectorPropertyMetadata` + `Connector.getTableProperties()` / `getSessionProperties()`） + +> **状态（复核 `53a753e0a1b`）：已删除**（`a7de939fba9`），选的是本节两个选项里的"删除"。值对象与 `Connector` 上那两个 getter 一并消失。**注意不要误伤同名方法**：`PluginDrivenExternalTable.getTableProperties()` 与 `ConnectorSessionImpl.getSessionProperties()` 是引擎侧另外两个活方法，与本节无关。 + +`ConnectorPropertyMetadata` 是一个 120 行、带泛型和 4 个工厂方法的完整值对象， +配套 `Connector` 上两个返回 `List>` 的方法（`Connector.java:235` 和 `:240`）。 + +全仓搜索（含测试目录）：**除了它自己的定义文件之外，`ConnectorPropertyMetadata` 这个类型名在整个仓库里一次都没出现过**。 +（注意不要与 `PluginDrivenExternalTable.getTableProperties()` 混淆，那是另一个同名方法，返回的是普通字符串 map。） + +这是一个完整设计好、但从未接线的属性描述子系统。 + +**建议**：要么删除，要么补上真实用途（例如驱动 `CREATE CATALOG` 的属性校验和 `SHOW` 类语句的属性文档）。 +保持现状是最差的选择——它给新连接器作者一个错误信号，以为需要声明属性元数据。 + +#### C5. `ConnectorPartitionHandle`（handle 包） + +> **状态（复核 `53a753e0a1b`）：已删除**（`d258eb20f2a`）。 + +一个空的标记接口，全仓零引用（fe-core 和所有连接器都没用过）。 + +**建议**：删除。 + +#### C6. 与"是否重写了方法"重复的能力声明 + +> **状态（复核 `53a753e0a1b`）：仍然成立。** 布尔位与建库方法都还在，仍然靠实现者手工保持同步；本节提的两个补救（改抛"不支持"异常 / 加契约测试）都没做。 + +`ConnectorSchemaOps.supportsCreateDatabase()`（`:58`）与 `createDatabase(...)`（`:63`）是一对： +前者返回 true 才会走"建库前先检查远端是否存在"的逻辑，后者是真正的建库实现。 +当前 4 个连接器（hive / iceberg / paimon / maxcompute）两者都实现了，暂时没有不一致。 + +问题在于这两者**在语义上必然同进同退**，却由实现者手工保持同步。 +一个新连接器只实现 `createDatabase` 而忘了 `supportsCreateDatabase`， +`CREATE DATABASE IF NOT EXISTS` 的行为就会悄悄退化，且没有任何检查会发现。 + +**建议**：删除布尔方法，改为让默认的 `createDatabase` 抛出一个引擎可识别的"不支持"异常， +引擎据此判断；或者至少加一条契约测试强制两者一致。 + +#### C7. `Connector` 上 6 个写特性的空安全转发 + +> **状态（复核 `53a753e0a1b`）：已删除**（`dfbefc790e8`），而且删得比本节建议的更彻底——不是"把空安全逻辑挪到引擎侧工具方法"，而是把这一族**连同 per-handle 变体共 11 个**（本节估的是 9 个）整体删掉，引擎改为先按表句柄取写计划提供者、再直接问它。副作用是 G1 描述的对称性缺口**在结构上不再可能存在**。 + +`Connector.java:132`–`:186` 有 6 个方法（`supportsWriteBranch`、`requiresParallelWrite`、 +`requiresFullSchemaWriteOrder`、`requiresPartitionLocalSort`、`requiresPartitionHashWrite`、 +`requiresMaterializeStaticPartitionValues`），每一个的实现都是同一句话： +"取写计划提供者，为 null 则返回 false，否则转发同名方法"。 + +核对结果：**没有任何连接器重写过 `Connector` 上的这 6 个方法**，全部只在 `ConnectorWritePlanProvider` 上实现。 +所以这 6 个方法纯粹是给引擎用的便利转发。 + +**建议**：这不算错误，但它让 `Connector` 接口膨胀了 6 个方法（加上 3 个 per-handle 变体共 9 个）， +新连接器作者需要判断"这些我要不要实现"。 +更干净的做法是把这段空安全逻辑放到引擎侧的一个工具方法里，`Connector` 只保留 `getWritePlanProvider(handle)`。 + +#### C8. 重载堆叠 + +> **状态（复核 `53a753e0a1b`）：部分处置。** 建表的两个重载已合成**一个**（javadoc 明写"刻意只保留一个 create"），删掉的正是本节点名的那个丢信息的 legacy 版；建库的 cascade 重载也已收成单个四参版本，javadoc 记下了旧重载导致 `DROP DATABASE ... FORCE` 静默不级联的原因。**`planScan` 的 4 个重载、以及"带快照 / 不带快照"那两组重载原样还在**，本节提的"一个方法 + 一个请求对象"没有做。 + +- `ConnectorScanPlanProvider.planScan` 有 **4 个重载**（4/5/6/7 参数），后一个默认委托给前一个。 + 新连接器必须读完 4 段文档才知道该实现哪一个。 +- `ConnectorTableOps.createTable` 有 2 个重载，旧的那个（`schema, properties`）会丢掉分区、分桶、`IF NOT EXISTS` 信息， + 文档自己称之为"legacy"。而且它的两个参数存在冗余——`ConnectorTableSchema` 里本来就有 `properties` 字段， + 默认实现（`:241`）把 `request.getProperties()` 同时塞进 schema 和第二个参数。 +- `ConnectorSchemaOps.dropDatabase` 有 2 个重载（是否 cascade）。 +- `ConnectorTableOps.getTableSchema` / `getColumnHandles`、`ConnectorStatisticsOps.getTableStatistics` + 各有"带快照"和"不带快照"两个版本。 + +**建议**：把参数逐步增长的重载合并成**一个方法 + 一个请求对象**。 +`ConnectorCreateTableRequest` 已经是这个模式的正确示范，`planScan` 应该照做 +（`ConnectorScanRequest` 承载 columns / filter / limit / requiredPartitions / countPushdown）， +这样以后再加规划维度就不用再开一个重载。带快照的那组重载可以把快照并入请求对象或做成可选参数。 + +--- + +### D. 能力声明有 5 套并存机制 + +这是新连接器作者最容易困惑的地方。目前"我支持某个功能"可以用 5 种完全不同的方式表达： + +| 机制 | 例子 | 引擎侧判断方式 | +|---|---|---| +| 1. 枚举集合 | `getCapabilities()` 返回 `SUPPORTS_VIEW` | 集合包含判断 | +| 2. 接口上的布尔方法 | `supportsCreateDatabase()`、`supportsTableSample()`、`supportsBatchScan()`、`supportsColumnHandleSnapshotPin()`、`supportsCastPredicatePushdown()`、`supportsSystemTableTimeTravel()` | 直接调用 | +| 3. getter 返回 null 表示不支持 | `getScanPlanProvider()`、`getWritePlanProvider()`、`getProcedureOps()`、`getEventSource()` | 判空 | +| 4. 窄的可选接口 + `instanceof` | `RewriteCapableTransaction`、`WriteBlockAllocatingConnectorTransaction` | 类型判断 | +| 5. 表级能力用字符串 CSV 传递 | `ConnectorTableSchema` 的 `__internal.connector.per-table-capabilities` 键，值是枚举名的逗号串 | 解析字符串 | + +五套机制的取舍确实各有道理（枚举适合静态、getter 适合有实现体、`instanceof` 适合"不支持就没有这个方法"）， +但目前**没有一处文档说明选择规则**，结果是同一类问题在不同地方用了不同解法。 +最典型的矛盾是：写能力（`WriteOperation` 集合）曾经在枚举里、后来搬到了 provider 上， +`ConnectorCapability` 的类注释还专门解释了这件事； +而扫描能力（`SUPPORTS_TOPN_LAZY_MATERIALIZE`、`SUPPORTS_NESTED_COLUMN_PRUNE`）却留在枚举里。 + +第 5 种尤其值得注意：把一组枚举值序列化成 CSV 字符串，塞进本来用于承载表属性的 map， +再由 fe-core 解析回枚举。它绕开了类型系统，出错时不会在编译期暴露，只会在运行时表现为"能力莫名其妙没生效"。 + +**建议**：定一条明确的规则并写进 `ConnectorCapability` 的类注释，例如： + +- 有实现体的能力（读、写、存储过程、事件源）→ 用 getter 返回 null 表达； +- 纯粹的布尔开关且引擎需要在**规划期静态判断**的 → 进 `ConnectorCapability` 枚举； +- 只有一种数据源需要的窄能力 → 独立的可选接口 + `instanceof`； +- 需要**按表**变化的能力 → 这是目前唯一确实缺失的机制，应该做成一个正经的接口方法 + （例如 `Set getTableCapabilities(session, handle)`），而不是 CSV 字符串。 + +> **状态（复核 `53a753e0a1b`）** +> +> - **第 5 种机制已经消失**（`5a6d76abadb`）：那个 `__internal.` 的 CSV 键全仓零命中，`ConnectorTableSchema` 上换成了类型化的 `Set` 字段与 getter，字段 javadoc 里还留了一句"它曾经是一个装枚举名 CSV 的保留键"。**本节建议的第 4 条已经落地**，形态与建议一致（载体是表 schema 而不是新的 `getTableCapabilities(session, handle)` 方法）——**现在再照建议加一个方法，会造出第二条并行通道**。 +> - **"没有一处文档说明选择规则"已被推翻**（`d572751af49`）：`fe-connector-api` 的 `package-info.java` 里现在有"规则一

`53a753e0a1b`）：已按域拆分**（`a9567456c44`），并且每个域接口都写了"最少实现集"。实际拆出来的 6 个域接口与本节提议的分组基本一一对应，只有三处命名不同：句柄/schema 组叫 `ConnectorTableMetadataOps`（不是继续叫 `ConnectorTableOps`）、列 DDL 组叫 `ConnectorColumnEvolutionOps`（不是 `ConnectorColumnDdlOps`）、分区枚举组叫 `ConnectorPartitionListingOps`（不是 `ConnectorPartitionOps`）；系统表那三个方法没有单独成组，并进了 `ConnectorTableMetadataOps`。`ConnectorTableOps` 自身现在只剩 2 个方法（`executeStmt` / `getColumnsFromQuery`，见 B 段），其余全在域接口里。 +> +> **连带后果**：本文 B 段与 C 段所有形如 `ConnectorTableOps.java:NNN` 的锚点，现在都指向一个已经不含那个成员的文件——核对时请按符号名去对应的域接口里找。 + +按语义分组： + +| 职责 | 方法 | +|---|---| +| 表句柄与 schema | `getTableHandle`、`getTableSchema`×2、`getColumnHandles`×2、`supportsColumnHandleSnapshotPin`、`listTableNames` | +| 系统表 | `listSupportedSysTables`、`getSysTableHandle`、`isPartitionValuesSysTable` | +| 视图 | `viewExists`、`listViewNames`、`getViewDefinition`、`dropView` | +| 表级 DDL | `createTable`×2、`dropTable`、`renameTable`、`truncateTable`、`renderShowCreateTableDdl` | +| 列 DDL | `addColumn`、`addColumns`、`dropColumn`、`renameColumn`、`modifyColumn`、`reorderColumns` + 5 个嵌套列版本 | +| 快照引用与分区规格 DDL | `createOrReplaceBranch`、`createOrReplaceTag`、`dropBranch`、`dropTag`、`addPartitionField`、`dropPartitionField`、`replacePartitionField` | +| 分区枚举 | `listPartitionNames`、`listPartitions`、`listPartitionValues` | +| 杂项 | `getPrimaryKeys`、`getTableComment`、`executeStmt`、`getColumnsFromQuery`、`buildTableDescriptor` | + +一个只读的连接器（比如一个新的对象存储格式）需要实现的只有第一组和"分区枚举"， +但它必须面对全部 43 个方法的文档才能确认这一点。 + +**建议**：按上表拆成 `ConnectorTableOps`（句柄/schema/列表）、`ConnectorViewOps`、`ConnectorTableDdlOps`、 +`ConnectorColumnDdlOps`、`ConnectorSnapshotRefOps`、`ConnectorPartitionOps` 若干个接口， +`ConnectorMetadata` 继续继承它们（对现有实现零影响，因为 Java 的接口继承是扁平的）， +但新连接器可以按需只看自己关心的那几个。这是纯粹的文档与认知成本优化，不改变任何运行时行为。 + +#### E2. `ConnectorScanPlanProvider` —— 24 个方法，混了 6 类东西 + +> **状态（复核 `53a753e0a1b`）：仍然完全成立。** 尤其是本节点出的那个矛盾——接口声称提供者"每次调用新建、无状态"，却要求它释放另一次调用中开启的读事务——原样存在，hive 仍然靠连接器级的读事务管理器绕过。这是全文仍然开放的问题里最实的一条。 + +规划（`planScan` 4 个重载 + `streamSplits` + `planScanForPartitionBatch`）、 +能力开关（`supportsBatchScan` / `supportsTableSample` / `supportsSystemTableTimeTravel` / `ignorePartitionPruneShortCircuit`）、 +Thrift 填充（`populateScanLevelParams` / `getDeleteFiles`）、 +EXPLAIN 渲染（`appendExplainInfo`）、 +诊断（`collectScanProfiles`）、 +**事务生命周期**（`releaseReadTransaction`）。 + +最后一项特别值得指出：接口自己的文档在 `getScanPlanProvider(handle)` 处写明 +"提供者是每次调用新建的、无状态的"（`Connector.java:76`）， +但 `releaseReadTransaction(queryId)`（`:539`）要求这个"无状态"对象能够释放另一次调用中开启的事务。 +hive 的实现只能靠把状态放在连接器级的 `HiveReadTransactionManager` 上来绕过这个矛盾 +（`HiveScanPlanProvider.java:347`）。也就是说，接口声明的对象生命周期和它承担的职责是冲突的。 + +**建议**：把每查询的读事务生命周期移到 `Connector` 上（连接器才是长生命周期对象）， +或者引入一个显式的"查询级资源"抽象；EXPLAIN 与诊断方法可以合并成一个"扫描诊断"接口。 + +#### E3. `Connector` —— 32 个方法 + +> **状态（复核 `53a753e0a1b`）：大部分已落地，方法数 34 → 21。** 本节列举的负担里，**REST 透传**、**属性描述**、**写特性转发（实为 11 个）** 三项已经删除或搬走；**缓存失效那 4 个 `invalidate*` 原样还在**，本节建议的"拆成 `ConnectorCacheInvalidation` 可选接口"没有做。异构网关路由（`ownsHandle` + per-handle getter）也还在，但 per-handle getter 从 4 组减到 3 组。 + +除了合理的入口方法外，还承担了：缓存失效（4 个 `invalidate*`）、连通性测试（3 个）、 +存储属性推导、schema 缓存 TTL 覆盖、REST 透传、属性描述（死接口）、异构网关路由（`ownsHandle` + 4 组 per-handle getter）、 +写特性转发（9 个）。 + +**建议**：至少把缓存失效（4 个方法）拆成一个 `ConnectorCacheInvalidation` 可选接口—— +大多数连接器不缓存任何东西，这 4 个方法对它们完全是噪音。 + +#### E4. `ConnectorContext` —— 19 个方法，引擎服务的大杂烩 + +包含：身份（catalog 名/id）、认证（`executeAuthenticated`）、HTTP 安全钩子、JDBC URL 清洗、 +缓存失效回调、兄弟连接器工厂、**存储相关的 8 个方法**（凭证归一化、URI 归一化 3 个重载、 +BE 文件类型、broker 地址、BE 存储属性、类型化存储属性、文件系统、空目录清理）、BE 连通性探测。 + +存储那 8 个方法明显自成一体，应该是一个独立的 `ConnectorStorageContext`（由 `ConnectorContext` 提供）。 + +> **状态（复核 `53a753e0a1b`）：仍然成立，一步未动。** `ConnectorStorageContext` 这个类型名全仓零命中，从未被创建过。这一条已经在另一条工作线里单独立项，被标为**高危**——它跨引擎与全部插件的边界，落地必须配插件包重部署冒烟。 + +#### E5. `ConnectorMetadata` 是一个约 70 方法的聚合接口 + +> **状态（复核 `53a753e0a1b`）：结构未变，自身方法 11 → 10**（"属性"那个已随 F4 一并删除）。本节指出的"MVCC 与 handle 改写方法散在 `ConnectorMetadata` 自身而不是一个 Ops 子接口里"仍然成立。注意它继承的 6 个接口是 `ConnectorSchemaOps` / `ConnectorTableOps` / `ConnectorPushdownOps` / `ConnectorStatisticsOps` / `ConnectorWriteOps` / `ConnectorIdentifierOps`——而 `ConnectorTableOps` 自己又继承了 6 个域接口，所以家族合计已是 75 个声明。 + +它继承 6 个 Ops 接口，自己再加 11 个（属性、5 个 MVCC 相关、3 个 handle 改写、快照 schema）。 +这些 MVCC 与 handle 改写方法（`applySnapshot`、`applyRewriteFileScope`、`applyTopnLazyMaterialization`） +在语义上属于同一族——"在规划前把某个信息织进表句柄"——但它们分散在 `ConnectorMetadata` 自身而不是一个 Ops 子接口里。 + +--- + +### F. 语义不清的接口 + +#### F1. `ConnectorScanRange.getLength()` 的单位不确定（`:56`） + +> **状态（复核 `53a753e0a1b`）：仍然成立，一步未动。** `getLength()` 的文档仍然只写"字节数"，各连接器的语义分歧原样存在，`supportsTableSample()` 这个补丁式的布尔开关也还在，仍然只有 hive 声明。 + +文档写"要读取的字节数，-1 表示整个文件"。 +实际语义按连接器而异：hive/iceberg 是字节数；MaxCompute 默认与 Paimon 的 JNI 分片返回 -1； +MaxCompute 的行偏移模式返回的是**行数**。 + +这个歧义已经产生过真实后果：任何"按大小做采样/切分"的通用逻辑都不能直接用这个值， +所以 `supportsTableSample()`（`ConnectorScanPlanProvider:268`）才不得不存在， +用一个额外的布尔开关来声明"我的 length 真的是字节数"。目前只有 hive 声明了它。 + +**建议**：把字段拆开——`getLengthInBytes()` 语义唯一，行数之类的连接器私有信息进 `properties`。 +在此之前，至少要把这个歧义写进 `getLength()` 的文档（现在文档是明确说"字节"的，与事实不符）。 + +#### F2. `null` 与空集合的三态区分 + +三处接口用"null 和空集合表示不同含义"来编码信息： + +- `ConnectorWritePlanProvider.getWriteSortColumns`（`:96`）：`null` = 无写排序；空 list = 有排序但列不可解析。 +- `ConnectorWritePlanProvider.getWritePartitioning`（`:119`）：`null` = 未分区；空 spec = 另一回事。 +- `ScanNodePropertiesResult`：靠一个 `hasConjunctTracking` 布尔区分"没有跟踪"和"跟踪了但全部下推"。 + +> **交叉核对修正：第二条不成立，应从本节删除。** `getWritePartitioning` 只有**两态**，不存在"空 spec = 另一回事"这个第三态。接口 javadoc 写得很明确，还给了理由：`null`（**而不是空 spec**）表示目标未分区，对齐旧实现的"是否已分区"判据，引擎据此回退到非分区的合并分布。唯一的生产者是 iceberg（未分区表返回 `null`，有测试钉住），唯一的消费者是引擎侧的行级合并写入节点，全仓没有任何一处让"空规格"表示第三种含义。 +> 同一节的另外两条（写排序列的 `null` vs 空 list、`hasConjunctTracking` 布尔位）**是真的**，且复核日仍然成立——写排序列的接口默认值确实是 `null`。 +> +> **状态（复核 `53a753e0a1b`）**：本节提的补救（改用 `Optional` 或显式的 `WriteOrdering.none()`）没有做。 + +这种编码方式很容易被实现者写反（返回 `Collections.emptyList()` 而不是 `null` 就会改变行为）， +而且编译器不会提醒。 + +**建议**：改用 `Optional>`，或者引入显式的 `WriteOrdering.none() / WriteOrdering.of(...)`。 + +#### F3. `ConnectorWriteHandle.getWriteContext()` 名不符实 + +> **状态（复核 `53a753e0a1b`）：仍然成立。** 连接器侧的方法名没改；而引擎侧现在已经在用本节提议的那个名字（`getStaticPartitionSpec()`），于是两个名字跨边界并存，比调研日更值得统一。 + +方法名是"写上下文"（暗示是一个自由的信息袋），但它的文档自己承认： +唯一的生产者只往里放静态分区规格，三个消费方（hive/iceberg/maxcompute）也都当静态分区规格用。 + +**建议**：直接改名为 `getStaticPartitionSpec()`。 + +#### F4. `ConnectorMetadata.getProperties()` 没有契约（`:54`） + +> **状态（复核 `53a753e0a1b`）：本节已作废——符号已删除**（`891709a08e7`），选的是本节两个选项里的"删除"。 + +文档只有一句"返回连接器级属性"。是 catalog 属性？是连接器自己派生的属性？给谁看的？ +在 fe-core 的插件驱动路径上找不到调用点。 + +**建议**：补充契约或删除。 + +#### F5. `ConnectorSession` 有三条读配置的路径且互相重叠 + +> **状态（复核 `53a753e0a1b`）：仍然成立，一步未动。** 两个命名空间仍在 `getProperty` 里被静默合并，同名时会话变量仍然静默覆盖 catalog 配置。 + +`getCatalogProperties()`（catalog 属性全集）、`getSessionProperties()`（会话变量全集）、 +`getProperty(name, type)`（`ConnectorSession.java:75`）。 +第三个的引擎实现（`ConnectorSessionImpl.java:131`）会**先查会话变量、再查 catalog 属性**—— +两个命名空间被静默合并，调用方无法知道拿到的值来自哪一边，同名时会话变量会静默覆盖 catalog 配置。 + +**建议**：让 `getProperty` 明确它查哪个命名空间，或者干脆删掉它（只有 hive 的 2 处在用）。 + +#### F6. 参数风格不统一：句柄 vs 字符串名 + +`ConnectorTableOps` 内部同时存在两种寻址方式： + +- 用表句柄：`getTableSchema(session, handle)`、`dropTable(session, handle)`、`listPartitions(session, handle, filter)`…… +- 用库名/表名字符串：`getPrimaryKeys(session, dbName, tableName)`、`getTableComment(session, dbName, tableName)`、 + `viewExists(session, dbName, viewName)`、`getViewDefinition(...)`、`dropView(...)` + +后者绕过了句柄，意味着连接器要么重新解析一次表、要么维护两条查找路径。 +更实际的影响是：**异构网关连接器无法按句柄把请求路由给正确的兄弟连接器**， +因为字符串参数里没有任何信息说明这张表属于哪种格式。 + +> **交叉核对修正：结论的后半句不成立。** 前半句是对的——网关**确实无法用"按句柄类型路由"这个惯用手法**去处理名字寻址的方法，这一点现在已经明文写进 SPI 文档（`ConnectorTableMetadataOps` 的接口注释专门有一段："某方法按**名字**而不是句柄寻址；异构网关按具体句柄类型把外来表路由给兄弟连接器，因此无法这样路由名字寻址的方法；如果你在写网关，必须显式处理它"）。 +> 但后半句"字符串参数里没有任何信息说明这张表属于哪种格式"是**错的**：网关完全可以拿库名/表名回查一次元数据再判定格式，hive 网关现在就是这么做的（取回 HMS 表对象 → 交给格式探测器 → 只对 iceberg 表返回注释，取不到就降级成空串）。这条路径正是靠它修好了"异构目录下 iceberg 表注释显示为空"这个用户可见缺陷。 +> +> **状态（复核 `53a753e0a1b`）**：本节建议的"统一为句柄寻址"没有做；名字寻址的那一组里，`getPrimaryKeys` 已随死接口面一并删除（`891709a08e7`），其余仍在。 + +**建议**：统一为句柄寻址。视图相关的方法确实可能在拿到句柄前调用，那就应该有一个明确的 +"库/表名寻址"分组并说明为什么，而不是与句柄方法混排。 + +#### F7. 两个方向相反但同名的失效接口 + +- `Connector.invalidateTable/invalidateDb/invalidateAll/invalidatePartition`（`Connector.java:312`–`:336`）： + **引擎 → 连接器**，用于 `REFRESH TABLE` 等命令通知连接器丢弃自己的缓存。 +- `ConnectorMetaInvalidator.invalidateTable/invalidateDatabase/invalidateAll/invalidatePartition/invalidateStatistics` + （`fe-connector-spi/.../ConnectorMetaInvalidator.java`）： + **连接器 → 引擎**，用于连接器收到元数据变更事件后通知引擎丢弃缓存。 + +两组方法名几乎完全一样、参数也几乎一样（只有 `invalidateDb` vs `invalidateDatabase`、 +以及 partition 参数一个是"分区名列表"一个是"分区值列表"这两处细微差别），方向却相反。 +这是一个非常容易写错的设计，而且写错了不会报错，只会表现为"缓存偶尔不刷新"。 + +> **状态（复核 `53a753e0a1b`）：命名冲突已经消失，本节的改名建议应当撤销。** +> "连接器 → 引擎"那一整套推模型（`ConnectorMetaInvalidator` 及其引擎侧实现）已由 `0a21334f95e` 删除——它是死的：连接器 `src/main` 里除了两个类加载器钉桩包装类的透明转发没有任何生产调用，而引擎侧实现自己在注释里承认按分区失效履约不了（降级成整表失效）、统计失效是空操作。反向的元数据变更通知现在走**拉模型**（引擎侧的事件同步驱动定期向连接器 `pollOnce`）。 +> 活着的那一组（`Connector.invalidate*`，引擎 → 连接器）原样保留。**不要**为了消歧义去给它改名而动 8 个连接器——名字已经不撞了。 + +**建议**：至少把其中一组重命名以体现方向（例如引擎→连接器的那组叫 `onRefreshTable/onRefreshDatabase`）， +并统一 partition 参数的语义（现在一个传规范化分区名、一个传分区值列表）。 + +#### F8. 用字符串 map 传递结构化信息 + +> **状态（复核 `53a753e0a1b`）：部分落地。** 七个保留键里，**表级能力那个已经提升为类型化字段**（`5a6d76abadb`，见 D 段状态戳），**主键列那个已随死接口面删除**（`891709a08e7`）。分区列、分桶列、以及三个"已渲染好的 SQL 子句"仍然靠字符串键传递，本节对它们的批评仍然成立。 + +`ConnectorTableSchema` 定义了 7 个 `__internal.` 前缀的保留键，用来在**表属性 map** 里夹带结构化信息： +分区列（CSV）、主键列（CSV）、分桶列（CSV）、表级能力（枚举名 CSV）、 +以及三个已渲染好的 SQL 片段（LOCATION 子句、PARTITION BY 子句、ORDER BY 子句）。 + +这么做的原因可以理解——避免为每种信息都往 `ConnectorTableSchema` 加字段。 +但代价是：这些本该是类型化字段的东西，现在靠字符串键约定传递，拼错一个键不会有任何提示。 +尤其是"已渲染的 SQL 子句"这三个键，等于让连接器直接生成 Doris SQL 文本， +把语法渲染的责任推给了插件；一旦 Doris 的 DDL 语法变化，所有连接器都要跟着改。 + +**建议**：把分区列/主键列/分桶列/表级能力提升为 `ConnectorTableSchema` 的正式字段（有类型、有默认值）； +三个 SHOW CREATE 相关的渲染键，改为让连接器返回结构化描述（例如分区字段 + 变换名 + 参数），由 fe-core 负责渲染文本。 + +--- + +### G. 对称性缺口与潜在缺陷 + +#### G1. 6 个写特性只有 3 个提供了"按表"变体 + +> **状态（复核 `53a753e0a1b`）：已落地，走的是本节推荐的那条路。** `dfbefc790e8` 把 `Connector` 上这一族转发方法（连同 per-handle 变体共 11 个）整体删除，引擎改为先 `getWritePlanProvider(handle)` 拿到提供者、再直接读特性。**"按表语义天然成立"因此兑现了，这个对称性缺口在结构上不再可能出现。** + +异构网关连接器（hive catalog 同时服务 plain-hive、iceberg-on-HMS、hudi-on-HMS 三种表） +需要按表决定用哪个写计划提供者。`Connector` 为此提供了带表句柄的重载，但**只覆盖了一半**： + +| 写特性 | 有连接器级方法 | 有按表变体 | +|---|---|---| +| `supportedWriteOperations` | 是 | 是 | +| `supportsWriteBranch` | 是 | 是 | +| `requiresPartitionHashWrite` | 是 | 是 | +| `requiresMaterializeStaticPartitionValues` | 是 | 是 | +| `requiresParallelWrite` | 是 | **否** | +| `requiresFullSchemaWriteOrder` | 是 | **否** | +| `requiresPartitionLocalSort` | 是 | **否** | + +核对当前实现：hive 与 iceberg 的 `requiresParallelWrite` 和 `requiresFullSchemaWriteOrder` **恰好都是 true**， +两者的 `requiresPartitionLocalSort` **恰好都是 false**（只有 MaxCompute 是 true）， +所以今天不会出错。但这属于"碰巧对齐"，不是设计保证。 + +一旦出现某个通过网关委派、且这三项与网关本身不同的表格式（例如把 MaxCompute 作为兄弟连接器接入）， +引擎就会拿网关自己的写特性去规划兄弟连接器的写入，表现为分布方式错误 → 输出文件数异常或写入结果不正确。 + +**建议**：要么补齐三个缺失的按表变体，要么（更好）取消这 9 个转发方法， +让引擎直接通过 `getWritePlanProvider(handle)` 拿到 provider 再读特性——那样按表语义天然成立，不存在对称性问题。 + +#### G2. 写能力自洽性校验从未在真实连接器上运行 + +> **交叉核对修正：本节的核心事实在调研日就是错的。** 用 `git grep` 回到 `7ff51a106f0` 复核，那一刻**已经有四个真实连接器的契约测试在调用** `validate`：iceberg、elasticsearch、jdbc、maxcompute。所以"8 个真实连接器没有任何一个调用过它""这 4 条规则今天完全没有被验证"两句都不成立，类注释描述的机制是**部分已经实现**的机制、不是虚构的机制。 +> 真实缺口比原文窄得多、也具体得多：**唯一声明"分区哈希写"的 hive 没有调用点**，因此涉及它的两条不变量缺少真实连接器的正样本，只有引擎侧那个假连接器测试在压。照原文"给 8 个连接器各补一个契约测试"去做，其中 4 个是重复建设，而真正缺的那一个原文根本没点出来、最可能被漏掉。 +> +> **状态（复核 `53a753e0a1b`）**： +> - 类注释已经修好（`29b46660ac4`），现在专门有一段"Actual coverage today"，写明四家在调、并点名 hive 是那两条不变量唯一的空白。**H2 那一小节因此整条作废。** +> - 调用点数量没变（4 个连接器 + 1 个引擎侧假连接器测试），但四家的**有效性**并不一样：es 是只读连接器，写计划提供者为 `null`，`validate` 一进来就早退，等于零条不变量被压到；jdbc 有写但四个前件全 `false`，属于空过；**真正压到真前件的只有 iceberg（声明分支写）与 maxcompute（声明分区本地排序）**。 +> - 本节提的"把检查扩展到按表变体"没有做，而且现在有了更明确的说法：验证器读的是连接器级提供者，引擎写路径按表解析提供者，异构网关可以在这里自洽却按表答得不同——这一点已被写进类注释，标为**有意为之、不在验证器职责范围内**。 + +`ConnectorContractValidator`（`fe-connector-api/.../ConnectorContractValidator.java`） +定义了 4 条写能力自洽规则（例如"要求分区本地排序就必须同时要求并行写和全 schema 顺序"、 +"两个分区分布模式互斥"）。它的类注释写着： + +> 这些不变量由**各连接器的契约测试**（构建每个连接器并调用 `validate`）来强制执行。 + +实际情况：全仓唯一的调用点是 `fe-core/src/test/.../ConnectorContractValidatorTest.java`， +它用的是**手写的假连接器**，8 个真实连接器没有任何一个调用过它。 + +也就是说这 4 条规则今天完全没有被验证。 +更关键的是：它只检查连接器级的方法，即使被调用，也检查不到 G1 描述的按表场景。

Layer 2 — the connector-agnostic per-statement `ConnectorMetadata` funnel + +**What it is.** A per-statement memoization arena (the Doris analog of Trino's per-transaction `CatalogMetadata`) that guarantees *one `ConnectorMetadata` instance per (statement, catalog)*, so every read / scan / DDL / MVCC / write resolver in a statement shares one metadata — and, for a connector that memoizes its loaded table on that metadata, one loaded remote table. + +Pieces, at HEAD: + +- **SPI seam (neutral):** `fe-connector-api/.../connector/api/ConnectorStatementScope.java`. Interface with `computeIfAbsent` (line 45), typed `getOrCreateMetadata` default (lines 55-57), best-effort idempotent `closeAll` default no-op (lines 66-67), and the `NONE` no-op scope that memoizes nothing (lines 70-75). Reached from a connector purely via `ConnectorSession.getStatementScope()`, whose SPI default is `NONE` (`ConnectorSession.java:142-144`) — so any connector that does nothing still compiles and behaves byte-identically to "load every time." +- **The funnel itself:** `fe-core/.../datasource/plugin/PluginDrivenMetadata.get(session, connector)` (lines 53-71). Keyed `"metadata:" + catalogId` (line 70); builds via `connector.getMetadata(session)` at most once per statement. It also pins the *building identity* under `"metadata-identity:" + catalogId` and throws `IllegalStateException` if a second Doris principal reuses the instance (lines 63-69) — turning a would-be cross-user credential reuse into a hard error. This is the **only** file in fe-core allowed to call `Connector#getMetadata` (enforced by gate §5). +- **The arena impl:** `fe-core/.../connector/ConnectorStatementScopeImpl.java`. A `ConcurrentHashMap` (line 44) so off-thread scan pumps that reuse the one session reach the same scope; `computeIfAbsent` (lines 49-51); **two-tier `closeAll`** (lines 64-98, guarded by `closed` for idempotency): pass 1 finalizes any `CatalogStatementTransaction` (rolls back an uncommitted txn), pass 2 closes every remaining `AutoCloseable` value (the memoized metadata) — txn finalized *before* the metadata it was minted from is closed. +- **The physical home:** `fe-core/.../nereids/StatementContext.java`. Field `connectorStatementScope` (line 209); lazily built by `getOrCreateConnectorStatementScope()` (lines 656-661); dropped/closed per prepared-statement execution by `resetConnectorStatementScope()` (lines 672-677); **fallback close** in `close()` for statements that never reach a coordinator (external DDL/SHOW/DESCRIBE/EXPLAIN/foreground ANALYZE), guarded by `isReturnResultFromLocal` (lines 995-997). +- **Write-transaction co-holder:** `fe-core/.../datasource/plugin/CatalogStatementTransaction.java`. Minted from the *shared* metadata's write facet via `begin()` (lines 80-84); `finalizeAtStatementEnd()` is the deterministic backstop (lines 100-107). Connector-agnostic — traffics only in neutral `ConnectorWriteOps`/`ConnectorSession`/`ConnectorTransaction` SPI types. + +**Lifecycle** (open → memoize → two-tier close): +1. **Open:** `ConnectorSessionBuilder.captureStatementScope()` (`ConnectorSessionBuilder.java:190-203`) reads the scope off the live `ConnectContext`'s `StatementContext` at session-build time (request thread). **This is *not* gated by connector type** — there is no `iceberg`/type branch; any session built from a live statement gets the real scope, else `NONE`. +2. **Memoize:** every resolver calls `PluginDrivenMetadata.get(...)`. Verified breadth at HEAD: **58 call sites across 15 fe-core files** (`PluginDrivenExternalCatalog/Table/Database`, `PluginDrivenMvccExternalTable`, `PluginDrivenScanNode`, `PluginDrivenInsertExecutor`, `BindSink`, `PhysicalPlanTranslator`, `PhysicalExternalRowLevelMergeSink`, `ShowPartitionsCommand`, `IcebergRowLevelDmlTransform`, `ConnectorExecuteAction`, `CallExecuteStmtFunc`, `MetadataGenerator`, `JdbcQueryTableValueFunction`). +3. **Close (two-tier):** primary is the getSplits query-finish callback — `PluginDrivenScanNode` registers `statementScope::closeAll` via `QeProcessorImpl.registerQueryFinishCallback`, skipping `NONE` (lines 1235-1237); fallback is `StatementContext.close()` (line 995). Both idempotent. + +**Cross-statement background loaders** are deliberately forced through a `NONE` scope (a read-through, not a hazard): `PluginDrivenExternalCatalog` builds their sessions `.withStatementScope(ConnectorStatementScope.NONE)` (lines 1161, 1168), so a synchronous background `fetchRowCount` cannot capture the live statement's scope. + +**Two connector-agnostic memos ride on top** (both byte-identical to re-resolving): +- `PluginDrivenScanNode.resolveScanProvider()` memoizes the `(handle, provider)` pair keyed on `currentHandle` *identity* via the immutable `ResolvedScanProvider` holder (lines 245-275), so the per-split `getFileCompressType`/`getDeleteFiles`/`classifyColumn` hot path stops re-allocating + TCCL-swapping a provider per split. This is the "generic-node provider memo (C14)." +- `PluginDrivenScanNode.metadata()` caches this node's funnel result in a volatile field (lines 189, 203-210) so per-method resolvers don't re-hit the scope map. + +**Heterogeneous-gateway extension (still Layer-2 mechanics, lives in the hive connector):** `HiveConnectorMetadata.memoizedSiblingMetadata()` (lines 302-304) memoizes the iceberg/hudi-on-HMS **sibling** metadata on *the same per-statement scope*, keyed `"metadata:" + catalogId + ":" + ownerLabel` (the three gateway connectors share one catalogId, so the owner label keeps them distinct — lines 293-295). It uses only `fe-connector-api` types (no fe-core dep). + +**Does Layer 2 already apply to ALL of `SPI_READY_TYPES`?** **Yes, universally, with no iceberg gate.** `SPI_READY_TYPES = {jdbc, es, trino-connector, max_compute, paimon, iceberg, hms}` (`CatalogFactory.java:56-57`); every one is a `PluginDrivenExternalCatalog` whose reads/scans go through `PluginDrivenExternalTable`/`PluginDrivenScanNode`, i.e. through the 58 funnel call sites; and `captureStatementScope()` has no type branch. hudi is not its own type — it is served only as a sibling under the hms gateway (`CatalogFactory.java:51-55`), and *that* path also rides the funnel via `memoizedSiblingMetadata`. + +**Caveat worth stating plainly:** the funnel guarantees *one metadata per statement*, but whether that collapses repeated remote loads is **per-connector** — it only helps if that connector's `ConnectorMetadata` (or its long-lived `Connector`) actually memoizes the loaded table/schema.

Connector-side copy of fe-core's `common.CacheFactory` (plugins can't import fe-core). +- **`CacheSpec`** — the `(enable, ttl-second, capacity)` config value; `fromProperties(props, engine, entry, default)` reads `meta.cache...*`; `CACHE_TTL_DISABLE_CACHE`(0)/`CACHE_NO_TTL`(-1) sentinels. This is exactly the knob every Layer-1 cache uses. +- **`MetaCacheEntry`** — the Caffeine-**free** unified cache-entry API: lazy/contextual loading, manual-miss-load (I/O outside Caffeine's lock, striped per-key dedup), key/predicate/full invalidation, and stats (`getLoadSuccessCount`, backing the `loadCountForTest` measurement gates). This is the shared engine under all six iceberg caches. +- **`MetaCacheEntryStats`** — the stats/`isEffectiveEnabled` view. +- **`ConnectorPartitionViewCache`** and **`PartitionViewCacheKey`** — an already-written **generic version of `IcebergPartitionCache`**: same contextual-only, manual-miss-load `MetaCacheEntry` shape, same `CacheSpec` wiring, but keyed by the engine-agnostic `PartitionViewCacheKey` with opaque value `V` and no engine imports. Its own javadoc states it "is the generic version of `IcebergPartitionCache`." + +**Who uses the substrate today** (verified imports/instantiations across `fe-connector/*/src/main/java`): +- `MetaCacheEntry`: **hive** (`HiveFileListingCache`), **hms** (`CachingHmsClient`), **iceberg** (all six above), **maxcompute** (`MaxComputePartitionCache`), **paimon** (`PaimonLatestSnapshotCache`). **Not** jdbc / es / trino-connector (none). +- `ConnectorPartitionViewCache` — actual `new …()` sites: **hive** `HiveConnector.java:136`, **iceberg** `IcebergConnector.java:281` & `:284` (mvcc view + list-partitions view), **paimon** `PaimonConnector.java:158`. + +**Is it the natural home to generalize Layer-1?** **Yes, and generalization is already underway.** The substrate exists, is Caffeine-free (safe across the loader split), reads a uniform `meta.cache...*` config namespace, and `ConnectorPartitionViewCache` is a *proof* that the exact iceberg pattern generalizes (it is `IcebergPartitionCache` with the key/value abstracted). The other five iceberg caches are structurally identical (all `new MetaCacheEntry<>(name, null, spec, commonPool, false, true, 0L, true)`), so `IcebergTableCache`/`IcebergCommentCache`/`IcebergFormatCache`/latest-snapshot could each collapse into a typed `ConnectorXViewCache` wrapper the same way. + +**One drift flag (Rule 7/12):** `ConnectorPartitionViewCache`'s class javadoc says "this class has **NO consumers yet**" — that is **stale at HEAD**: three connectors (hive, iceberg, paimon) already instantiate it. Worth a doc-only fix. + +--- + +## 4. Layer 3 — authorization cache isolation under `iceberg.rest.session=user` + +The hazard: name-only-keyed caches would let a user who can `LIST` but not `LOAD` a table receive metadata a *different* user's `loadTable` produced ("list ≠ load" disclosure), because per-user authorization lives *inside* the delegated `loadTable` round-trip. + +**iceberg-REST-specific mechanisms:** +- `IcebergConnector.isUserSessionEnabled()` (`:870-874`) = `rest.session == user` **and** flavor is REST. +- Under it, the connector **nulls** its live cross-query caches in the constructor: latest-snapshot (`:231`), table (`:243`, also nulled for REST vended-creds), partition (`:254`), format (`:260`), and both `ConnectorPartitionViewCache` instances (`:279`, `:282`). `IcebergCommentCache` is *only* built for REST-vended-and-not-session-user (`:269`). So under `session=user` every shared cache is off → `beginQuerySnapshot`/reads go live per-user. Each field carries the reviewed marker `authz-cache-session-user-disabled` or `authz-cache-exempt` (enforced by gate §5). + +**fe-core-general mechanisms** (apply to *any* `SUPPORTS_USER_SESSION` connector, not just iceberg — iceberg-REST is simply the only one that currently declares the capability): +- `ExternalCatalog.shouldBypassSchemaCache(SessionContext)` — base default `false` (`ExternalCatalog.java:367-369`); the generic name-keyed schema cache is bypassed live when true. +- `PluginDrivenExternalCatalog` overrides it as `supportsUserSession() && ctx != null && ctx.hasDelegatedCredential()` (`:1212-1214`), with sibling `shouldBypassTableNameCache` (`:1190-1192`) and `shouldBypassDbNameCache` (`:1200-1202`) closing the same disclosure at the db-name/table-name-cache level. Consumed by `ExternalTable.java:439`. + +So Layer-3 is split: the *policy predicate* (`shouldBypass*`, capability+credential gated) is connector-general fe-core; the *cache-nulling* is iceberg-connector-local because that's where the caches live. + +--- + +## 5. The two anti-drift build gates + +- **`tools/check-fecore-metadata-funnel.sh`** — **connector-GENERAL.** Fails the build on any executable `Connector#getMetadata()` in `fe/fe-core/src/main/java` outside the one legal carrier `datasource/plugin/PluginDrivenMetadata.java` (allow-list: the funnel file; a `getMetadata-funnel-exempt` marker; no-arg `getMetadata()`; comment lines). Invariant enforced: *one `ConnectorMetadata` per (statement, catalog) for every connector* — i.e. Layer 2. Its root is `fe/fe-core`, no iceberg specificity (lines 20-59, 67-105). +- **`tools/check-authz-cache-sharding.sh`** — **iceberg-ONLY.** `TARGET_REL` is hard-coded to `fe-connector-iceberg/.../IcebergConnector.java` (line 57); it requires every `final …Cache[ <]` holder field there to carry `authz-cache-session-user-disabled` or `authz-cache-exempt` (lines 65-96). Invariant enforced: *no new shared cross-query cache on IcebergConnector without a declared `session=user` isolation discipline* — i.e. Layer 3, for iceberg. It explicitly notes the fe-core schema cache is a *different* cache protected separately by `shouldBypassSchemaCache` (lines 37-39). If a second connector ever declares `SUPPORTS_USER_SESSION`, this gate would need a new target — it does not generalize as written. + +--- + +## 6.

Trino claims are grounded in the actual current source I fetched (`InMemoryTransactionManager`, `CatalogMetadata`, `CatalogTransaction`, `SharedHiveMetastoreCache`); where I rely on architectural knowledge rather than a fetched line I say so. + +--- + +## 1. Trino's per-transaction metadata lifecycle, and how faithful the Doris Layer-2 funnel is + +### 1a. What Trino actually does + +The lifecycle unit in Trino is the **transaction**, not the session and not the statement. Three layers cooperate: + +- **`InMemoryTransactionManager.TransactionMetadata`** holds `activeCatalogs`, a `ConcurrentHashMap`. `getTransactionCatalogMetadata(catalogHandle)` lazily does `catalog.beginTransaction(...)` on first touch of a catalog and caches the resulting `CatalogMetadata` for the transaction; `asyncCommit()`/`asyncAbort()` iterate `activeCatalogs.values()` and `commit`/`abort` each exactly once. (fetched from `InMemoryTransactionManager.java`.) +- **`CatalogMetadata`** wraps up to three `CatalogTransaction`s (the normal catalog, `information_schema`, system tables). `getMetadata(session)` returns the normal one; `getMetadataFor(session, handle)` routes by handle. (fetched from `CatalogMetadata.java`.) +- **`CatalogTransaction`** is where the one-metadata-per-transaction guarantee physically lives: + ``` + @GuardedBy("this") private ConnectorMetadata connectorMetadata; + synchronized ConnectorMetadata getConnectorMetadata(Session session) { + if (connectorMetadata == null) { + ConnectorSession cs = session.toConnectorSession(catalogHandle); + connectorMetadata = connector.getMetadata(cs, transactionHandle); + } + return connectorMetadata; + } + ``` + and `commit()`/`abort()` are gated by an `AtomicBoolean finished` so the connector transaction finishes once. (fetched from `CatalogTransaction.java`.) + +Two structural properties fall out of this and matter for Doris: + +1. **The `ConnectorMetadata` instance lives for the whole transaction and is the memo home.** Because Trino hands the connector one long-lived instance per transaction, connectors keep per-transaction working state *on that instance* (Iceberg's `IcebergMetadata` retains loaded tables/statistics; Hive's metadata holds a per-transaction metastore view). Repeated `resolveTable`/`getTableStatistics` within the transaction therefore collapse **for free** — the engine never needs a separate "load once per statement" seam. +2. **`getMetadata(session, transactionHandle)`** — the transaction handle is woven into the metadata at creation, so read and write are the same transaction by construction. `MetadataManager` (the engine's façade) routes every metadata call to `transactionManager.getCatalogMetadata(...).getMetadata(session)`, i.e. always through this cached instance. + +### 1b. What Doris does, and whether the emulation is sound + +Doris cannot use the session as the memo home, and the framework is explicit about why: + +- `ConnectorSessionImpl` is **immutable** and is **rebuilt** at each seam (`ConnectorSessionBuilder`); the PR cites ~26 rebuilds/statement. I confirmed the load-bearing fact — the session is immutable (`ConnectorSessionImpl.java:36`, all fields `final`) and constructed on demand rather than retained — so it *cannot* carry mutable per-statement memo. I did not independently count 26. +- Instead the memo hangs on the one **`StatementContext`**: `getOrCreateConnectorStatementScope()` (`StatementContext.java:656`) lazily builds a `ConnectorStatementScopeImpl` (`StatementContext.java:209` field). The scope is a `ConcurrentHashMap` (`ConnectorStatementScopeImpl.java:44`). +- Each session **captures the scope reference at build time** (`ConnectorSessionBuilder.captureStatementScope()` :190–203) so off-thread scan pumps that reuse one session still reach the same scope even without a `ConnectContext` thread-local — the direct analog of Trino handing the same `CatalogTransaction` to every operation on the transaction. +- The funnel is **`PluginDrivenMetadata.get(session, connector)`** (`PluginDrivenMetadata.java:53`), which memoizes `connector.getMetadata(session)` under key `"metadata:"+catalogId` on the scope (:70). This is the Doris analog of `CatalogTransaction.getConnectorMetadata`. It is the *only* place fe-core may call `Connector#getMetadata` — enforced build-wide by `tools/check-fecore-metadata-funnel.sh` (present, executable). I count **59** call sites in fe-core routed through it. + +**Assessment — is hanging the memo on `StatementContext` (not the session) sound?** Yes, with two caveats worth stating plainly: + +- **Sound mechanically.** The session is the wrong home precisely because it is immutable and rebuilt; the `StatementContext` is the one object that lives exactly as long as the statement and is reachable from every seam. The `ConcurrentHashMap` + `computeIfAbsent` gives every caller of a key the same instance (required because scan and write both mutate the shared table/delete-supply). Teardown is deterministic and idempotent: `closeAll()` (`ConnectorStatementScopeImpl.java:65`) runs two ordered passes (finalize any `CatalogStatementTransaction`, then close every `AutoCloseable` metadata), fired from the `getSplits` query-finish callback (`PluginDrivenScanNode.java:1237`) with a `StatementContext.resetConnectorStatementScope()` fallback (`StmtExecutor.java:1077`, `ExecuteCommand.java:95`). This mirrors Trino's `activeCatalogs.values()` commit/abort sweep + `AtomicBoolean finished`. +- **Caveat 1 — statement ≠ transaction.** Trino's unit is the whole `BEGIN…COMMIT` block; a multi-statement Trino transaction shares one `ConnectorMetadata` (and one connector transaction) across all its statements. Doris's unit is **one statement** (the scope key includes `queryId`, e.g. `IcebergStatementScope.java:64`), and a prepared-statement `EXECUTE` explicitly *drops* the scope per execution (`resetConnectorStatementScope`). For external-catalog reads and autocommit external DML (iceberg/hive) this is equivalent, because each such statement is its own transaction. But the read-consistency-within-a-transaction guarantee Trino gives across a multi-statement block is, in Doris, only a within-*statement* guarantee. Fine today; document it so nobody assumes cross-statement metadata sharing. +- **Caveat 2 — the metadata carries no transaction handle.** Trino's `getMetadata(session, transactionHandle)` bakes the transaction in; Doris's `getMetadata(session)` does not, and recovers write-transaction coupling with a *separate* co-holder (`CatalogStatementTransaction`, see §4) plus a **fail-loud identity pin** (`PluginDrivenMetadata.java:63–69`): the memo records the building user and throws if a second identity reuses the instance. Trino never needs that check because a transaction is single-identity by construction; Doris adds it because one shared singleton connector serves all users and a `session=user` metadata bakes in a delegated credential. This is a reasonable adaptation, not a defect. + +**Net:** the emulation is faithful in shape (lazy one-metadata-per-(statement,catalog), deterministic teardown, single routing funnel, arch-gate-enforced) and the choice to hang it on `StatementContext` is the correct — indeed the only — option given Doris's immutable-rebuilt session. + +--- + +## 2. Cross-transaction connector caches: the long-lived-shared vs per-transaction-view split + +### 2a. Trino + +Trino keeps a **long-lived shared cache** separate from a **per-transaction view**, per connector: + +- **Metastore.** `CachingHiveMetastore` is the shared, TTL-bounded cache (`getTable`, `getPartition(s)`, `getTableStatistics`/`getPartitionStatistics`, `listPartitionNames`). `SharedHiveMetastoreCache.ImpersonationCachingHiveMetastoreFactory` holds a `LoadingCache` **keyed by identity user** (`cache.getUnchecked(identity.getUser())`), configured `expireAfterWrite(userCacheTtl)` + `maximumSize(userCacheMaximumSize)` — i.e. under impersonation the cache is **sharded per identity**, not shared across users (fetched from `SharedHiveMetastoreCache.java`; corroborated by PR #9482 "add impersonation to SharedHiveMetastoreCache and remove per-user metadata caching from CachingHiveMetastore"). Over that shared cache Trino layers a **per-transaction `CachingHiveMetastore`** (the `createPerTransactionCache`/memoize wrapper) so that within one transaction repeated reads are consistent and never re-hit the metastore. +- **Directory listing** is a *separate* cache layer: `CachingDirectoryLister` (shared) with `TransactionScopeCachingDirectoryLister` giving the per-transaction consistent view — deliberately not folded into the metastore cache. +- **Iceberg** caches the resolved `Table` in the `TrinoCatalog` implementations (a Caffeine `Cache` gated by the `iceberg.metadata-cache` / expiration config), and `IcebergMetadata` additionally holds per-transaction working state on the instance. +- **Invalidation** is TTL + explicit: `CachingHiveMetastore.invalidateTable(...)` is called around writes so a write *within the transaction* invalidates the relevant entries; the per-transaction wrapper prevents a stale read of the just-written table. + +### 2b. Doris equivalents at HEAD + +Doris re-homed exactly this shape inside the connectors (the SPI cutover had left plain-hive caching nothing once a catalog became plugin-driven): + +| Trino | Doris (HEAD) | +|---|---| +| `CachingHiveMetastore` (metastore RPCs) | `CachingHmsClient` — decorates `HmsClient`, caches `getTable`/`listPartitionNames`/`getPartitions`/`getTableColumnStatistics`, each on its own `MetaCacheEntry`, keyed to Trino/legacy shape; class doc explicitly cites "Trino `CachingHiveMetastore` shape" (`fe-connector-hms/.../CachingHmsClient.java`) | +| `CachingDirectoryLister` / `TransactionScopeCachingDirectoryLister` | `HiveFileListingCache` — memoizes `FileSystem.listStatus` per `(db,table,location)` on a `MetaCacheEntry`; doc cites "Trino keeps the equivalent `CachingDirectoryLister` as a layer separate from its metastore cache" (`fe-connector-hive/.../HiveFileListingCache.java`) | +| Iceberg `TrinoCatalog` table cache + metadata memo | Two-level: cross-query `IcebergTableCache` (`getOrLoad`, `IcebergTableCache.java:86`) **plus** per-statement `IcebergStatementScope.sharedTable` (`IcebergStatementScope.java:59`), reached from `IcebergScanPlanProvider.resolveTable` (:2353 → `loadRawTable` :2378) | +| Iceberg partition/format/comment/manifest/snapshot metadata caches | `IcebergPartitionCache`, `IcebergFormatCache`, `IcebergCommentCache`, `IcebergManifestCache`, `IcebergLatestSnapshotCache`, plus the generic derived `ConnectorPartitionViewCache` (`IcebergConnector.java:169–203`) | + +**How Doris splits shared vs per-statement:** the cross-query caches live as `final` fields on the long-lived per-catalog connector (rebuilt only by `REFRESH CATALOG`), and the per-statement view is the `StatementContext` scope. For iceberg this is a genuine two-level split (`sharedTable` over `IcebergTableCache`) that matches Trino's per-transaction-view-over-shared-cache. For hive, `CachingHmsClient`/`HiveFileListingCache` are shared-only; the per-statement view is only the single `ConnectorMetadata` the funnel memoizes. + +**Invalidation** is coarser than Trino by design: Doris uses TTL + `REFRESH TABLE/DATABASE/CATALOG` flush (`IcebergTableCache.invalidate/invalidateDb/invalidateAll`; `CachingHmsClient.flush/flushDb/flushAll`). The `CachingHmsClient` doc states it **does not self-invalidate around writes** ("coarse REFRESH + TTL bound staleness"). Trino *does* invalidate within the transaction around a write. **Gap:** a Doris-side write leaves a TTL-bounded stale window for a subsequent read of the same table (no read-your-write within the coarse cache). Recommendation: either add write-path invalidation to `CachingHmsClient` or force the post-write read through a live (scope-`NONE` / bypass) read, matching Trino's per-transaction invalidation. + +**Authorization.** This is the sharpest divergence. Trino, under impersonation, **still caches but shards the cache key by identity** (`LoadingCache`). Doris, under `iceberg.rest.session=user`, **disables the caches entirely** — `latestSnapshotCache`/`tableCache`/`partitionCache`/`formatCache`/`commentCache` are set `null` under `isUserSessionEnabled()` (`IcebergConnector.java:231–273`), and fe-core adds `shouldBypassSchemaCache(SessionContext)` so schema is re-read live per user. This is enforced by `tools/check-authz-cache-sharding.sh` (every cache field must carry `authz-cache-session-user-disabled` or `authz-cache-exempt`). It is *safe* (it closes the "can-LIST-cannot-LOAD" metadata-disclosure the name-only keys would leak) but it is **coarser and slower** than Trino: `session=user` catalogs get no cross-query metadata cache at all. Recommendation (future): follow Trino and **key the caches by identity** rather than disabling them, restoring caching under `session=user`. That is a larger change (every key gains a user dimension) and the current "disable" is the correct conservative first cut. + +--- + +## 3. The unification question — does Trino have one generic connector cache, or per-connector caches on a shared toolkit? + +**Trino has no single unified connector cache.** It has a shared **low-level toolkit** — `io.trino.cache` (`EvictableCacheBuilder`, `SafeCaches`, `NonEvictableCache`/`NonKeyEvictableLoadingCache`, `CacheStatsMBean`) over Guava/Caffeine — and each connector builds *its own* caches on top: `CachingHiveMetastore`, `CachingJdbcClient`, the Iceberg catalog `tableCache`, `CachingDirectoryLister`. The reused unit is the *builder + eviction-safety + stats* machinery, not a cache and not a cache key model. This is deliberate: the cached objects and their key/invalidation/authorization semantics differ irreducibly per connector (an iceberg `Table` is not an `HmsTableInfo` is not a paimon `Table`). + +**Doris is already on this Trino-correct path.** `fe-connector-cache` is exactly the shared toolkit: `MetaCacheEntry` (Caffeine encapsulated behind a Caffeine-free API, striped single-flight locks, manual-miss-load, stats — `MetaCacheEntry.java`), `CacheSpec`, `CacheFactory`, and the one genuinely generic reusable *cache* `ConnectorPartitionViewCache`/`PartitionViewCacheKey`. Adopters confirmed by import: **hive, hms, iceberg, maxcompute, paimon** all build on `MetaCacheEntry`/`CacheSpec`/`ConnectorPartitionViewCache`; the only direct-Caffeine use in a connector is `org/apache/iceberg/DeleteFileIndex.java`, which is vendored iceberg code, not a Doris cache. + +**Lesson for the "unify the connector cache framework" goal:** + +1. **Do not build a single connector-agnostic metadata cache.** Trino proves the right seam is the toolkit, because the cached value types and their invalidation/authz rules are per-connector. Doris already has that toolkit (`MetaCacheEntry`) and it is already broadly adopted. Unifying *harder* than Trino (one cache to rule them all) would fight the same semantics Trino refused to fight. +2. **The real unification opportunity Doris is missing is not the caches — it is the per-statement dedup.** Trino gets "load each table once per transaction" *for free* because the `ConnectorMetadata` instance is the transaction-lived memo home (§1a-1). Doris's funnel guarantees one `ConnectorMetadata` per statement, but whether repeated `resolveTable` within that statement collapses is **per-connector and not uniform** — see §5. Iceberg routes table loads through the statement scope (`IcebergStatementScope.sharedTable`); the others do not. The highest-value "unification" is a shared **"resolve table via the statement scope"** helper so every connector inherits one-load-per-statement, closing the Variant-B gap uniformly instead of connector-by-connector. +3. **Converge the last bespoke caches onto `MetaCacheEntry`** — notably paimon still lacks a cross-query raw-`Table` cache (§5), and jdbc/es keep their own structures. + +--- + +## 4. Write-path consistency — read + write sharing one metadata / one transaction + +**Trino.** Read and write share the identical `ConnectorMetadata` for the transaction (the single `CatalogTransaction.connectorMetadata`): `beginInsert`/`finishInsert`/`beginMerge`/`finishMerge` are invoked on the same instance the reads used, and the connector transaction is finished by `CatalogTransaction.commit()`/`abort()` on the same `transactionHandle`. The write therefore sees exactly the reads' snapshot; there is one handle, one metadata, one commit. + +**Doris (HEAD).** The framework copies this "one-metadata-one-write-transaction-per-statement" model deliberately: + +- The **8 write-path `getMetadata` seams are routed through the same `PluginDrivenMetadata` funnel**, so read and write share the one memoized `ConnectorMetadata`, guarded by the fail-loud identity pin (`PluginDrivenMetadata.java:63–69`) — a `session=user` metadata baking in one user's delegated credential can never be silently reused to execute another user's write. +- The write transaction is hoisted into **`CatalogStatementTransaction`** (`CatalogStatementTransaction.java`), co-held on the scope next to the shared metadata. `begin(writeHandle)` mints the connector transaction from the **shared metadata's own write facet** (`writeOps.beginTransaction(session, writeHandle)`, :81) and registers it in `PluginDrivenTransactionManager`, so the write inherits exactly the read arm's client/ops — the class doc explicitly names this "mirroring Trino's `CatalogTransaction`: one metadata instance and one transaction per (statement, catalog)." +- Teardown is the deterministic two-pass in `closeAll()`: pass 1 `finalizeAtStatementEnd()` rolls back a transaction the executor never committed (only a mid-flight abort leaves one active), pass 2 closes the shared metadata — transaction is always finished **before** the instance it was minted from is closed (`ConnectorStatementScopeImpl.java:70–96`, `CatalogStatementTransaction.java:100`). `finalizeAtStatementEnd` is a no-op on every normal path (the executor already finished the txn, so the manager no longer holds it), and can never undo a committed write. + +**Faithfulness / gaps:** +- Faithful in the essential: read and write provably share one metadata and one connector transaction, torn down in the right order, with a fail-loud cross-identity guard Trino gets structurally. +- **Narrower scope than Trino:** the co-holder is per-*statement* (per `queryId` scope), so a *multi-statement* Doris transaction that mixes external writes and reads does not share one metadata/txn across statements the way a Trino `BEGIN…COMMIT` does. For Doris's autocommit external DML (iceberg/hive) this is equivalent; flag it if multi-statement external transactions are ever targeted. + +--- + +## 5.

The three places it diverges from Trino are all worth tracking: + +1. **Per-statement table dedup is non-uniform** — Trino gets it for free from the transaction-lived metadata instance; Doris has it only for iceberg (via the scope). **This is the single highest-value generalization** and the true meaning of "unify the connector cache framework": a shared statement-scope table-resolution helper, not a shared cache. Paimon is the concrete offender (transient-on-handle only, no cross-query table cache). +2. **Write-path cache invalidation** — Doris relies on coarse REFRESH+TTL where Trino invalidates within the transaction (read-your-write gap). +3. **`session=user` authorization** — Doris *disables* caches where Trino *shards by identity*; correct-but-slow, and the natural next step is Trino-style per-identity keying. + +Sources: [InMemoryTransactionManager](https://github.com/trinodb/trino/blob/master/core/trino-main/src/main/java/io/trino/transaction/InMemoryTransactionManager.java), [CatalogMetadata](https://github.com/trinodb/trino/blob/master/core/trino-main/src/main/java/io/trino/metadata/CatalogMetadata.java), [CatalogTransaction](https://github.com/trinodb/trino/blob/master/core/trino-main/src/main/java/io/trino/metadata/CatalogTransaction.java), [SharedHiveMetastoreCache](https://github.com/trinodb/trino/blob/master/lib/trino-metastore/src/main/java/io/trino/metastore/cache/SharedHiveMetastoreCache.java), [PR #9482 (impersonation in SharedHiveMetastoreCache)](https://github.com/trinodb/trino/pull/9482). \ No newline at end of file diff --git a/plan-doc/connector-cache-unification/appendix-C-funnel-universality.md b/plan-doc/connector-cache-unification/appendix-C-funnel-universality.md new file mode 100644 index 00000000000000..3dd487052a1f00 --- /dev/null +++ b/plan-doc/connector-cache-unification/appendix-C-funnel-universality.md @@ -0,0 +1,77 @@ +All evidence is grounded.

EsConnectorMetadata.getTableSchema builds `new ConnectorTableSchema(indexName, columns, "ELASTICSEARCH", Collections.emptyMap())` (EsConnectorMetadata.java:90-93) — an EMPTY properties map; the raw mapping JSON is discarded. But EsMetadataFetcher.fetchMapping needs the raw mapping (keyword-sniff / doc_value / date-compat) via EsMappingUtils.resolveFieldContext(columnNames, sourceIndex, indexMapping, mappingType) (EsMetadataFetcher.java:57-63). So the scan-path field context CANNOT be derived from the currently cached schema value. | The redundant remote mapping fetch (ES-F2) is REAL and the multiplier holds, but the proposed fix is understated: eliminating it requires either enriching ConnectorTableSchema to carry the raw mapping/field-context, or adding a per-statement/cross-query mapping (field-context) cache — i.e. it is NOT a zero-new-cache 'just reuse the schema' change.

Layer-2 funnel memo keyed "metadata:"+catalogId + identity pin "metadata-identity:"+catalogId via getUser (PluginDrivenMetadata.java:64,70). ResolvedScanProvider memo keyed on currentHandle identity (PluginDrivenScanNode.java:254-256, class at 267). RowCountCache at PluginDrivenExternalTable.java:907. No dedicated connector scan-metadata cache — confirmed absent (EsScanPlanProvider re-fetches). + +FUNNEL PARTICIPATION — CONFIRMED (funneled=true, metadataMemoizesLoadedTable=no). EsConnectorMetadata holds only restClient+properties; getTableSchema (81-94) calls restClient.getMapping every call; getColumnHandles (97-106) re-invokes getTableSchema -> 2nd remote GET; no memo fields. EsScanPlanProvider is a separate object (EsConnector.java:56-58 returns new provider each call), memoized only per scan node. + +HOT-PATH FINDINGS — all four CONFIRMED: +- ES-F1 (P1, 2x, not memoized): fetchMetadataState called from planScan (EsScanPlanProvider.java:99, reached via getSplits->planScan at PluginDrivenScanNode.java:1303) AND from buildScanNodeProperties (line 169, reached via getScanNodePropertiesResult at PluginDrivenScanNode.java:1863). getOrLoadPropertiesResult IS cached (cachedPropertiesResult, line 1838/1870), so the second path fires exactly once — 2x total, constant, verified. Each fetch = fetchMapping+searchShards+getHttpNodes (EsMetadataFetcher.java:51-89); NODES_DISCOVERY_DEFAULT="true" (EsConnectorProperties.java:38) so getHttpNodes really runs. planScan loop (113-138) is over an in-memory routing map with no remote call — correctly characterized as variant B/D, not loop-amplified. +- ES-F2 (P1, ~2x): fetchMapping->getMapping (EsMetadataFetcher.java:57-58; RestClient:161-168) duplicates the schema-resolution mapping fetch. Real; see correction on fix scope. +- ES-F3 (P2, 2x): buildColumnHandles (PluginDrivenScanNode.java:1917-1920) -> getColumnHandles -> getTableSchema -> raw getMapping, bypassing ExternalSchemaCache; buildColumnHandles runs at 1263 (getSplits) and 1841 (getOrLoadPropertiesResult) — 2x confirmed. +- ES-F4 (P2, 1x/handle): getTableHandle->existIndex `_mapping` GET (EsConnectorMetadata.java:74; RestClient:104-114). Confirmed low-cost. + +Per-SELECT remote tally (~4x getMapping + 2x searchShards + 2x _nodes/http) reproduces from the code. No missed P0: no heavy op sits in a per-split/per-file loop, so the audit does not UNDERSTATE anything — worst case is constant-factor. + +AUTHZ — CONFIRMED. Single catalog-level Basic credential (EsConnector.java:95-100; RestClient:76-78); no session=user/OIDC/kerberos. EsConnectorMetadata overrides no write/partition/comment/stats methods (grep for getTableStatistics/listPartitions/getTableComment/beginWrite/applyFilter returned nothing) — read-only, non-partitioned confirmed. authz-session-user-isolation N/A is correct.

fail-loud guard at HiveConnector.java:548-556 lives inside getOrCreateIcebergSibling and its error text is iceberg-specific ('iceberg-on-HMS sibling ... unexpectedly declares SUPPORTS_USER_SESSION'). getOrCreateHudiSibling (:576-591) has NO equivalent guard, so the '548-562 mirrored contract' does not literally cover the hudi sibling. | hudi's authz-safety instead rests on two verified facts: (a) HudiConnector does not override getCapabilities, so it inherits the empty default with no SUPPORTS_USER_SESSION (confirmed — the only getCapabilities hits are javadoc in HudiConnectorMetadata, no override); and (b) the hive front door itself is never session=user. The audit's substantive conclusion (name-only caches are authz-safe, no Layer-3 isolation / shouldBypassSchemaCache needed) is UNCHANGED and correct. | | +| HD-P03 multiplier: '3x within one pass' partition metadata-table scans for a filtered partitioned SELECT. | For a FILTERED query the code deliberately dedups to ~1 listing: applyFilter (non-hive-sync) lists once at HudiConnectorMetadata.java:289-291, then resolvePartitions returns the prunedPaths and short-circuits WITHOUT calling listAllPartitionPaths (HudiScanPlanProvider.java:635-638). The connector's own comment at HudiConnectorMetadata.java:288 states 'a filtered query lists exactly once (here) instead of there.' So '3x within one pass' is an upper bound, not the single-pass norm. | The '3x' only materializes when fe-core independently invokes multiple of listPartitions / listPartitionNames / listPartitionValues (each re-calls collectPartitions -> a fresh HoodieTableMetadata scan, HudiConnectorMetadata.java:707-713) and/or on an UNFILTERED scan where resolvePartitions does list (HudiScanPlanProvider.java:648). The CORE finding — a metadata-table partition scan re-run at multiple entrypoints with NO (table,instant)-keyed cache — is CONFIRMED; only the per-pass count is query-shape-dependent. | | +| HD-P01 multiplier '~5-6x per planning pass' and HD-P05 citation 'planScan.buildHadoopConf (:912-927)'. | Several metaClient build sites are conditional: applyFilter builds one only when a partition predicate is present AND non-hive-sync (:289-291); getScanNodeProperties builds one only when !force_jni (:363); the 3-arg MVCC getTableSchema fires only on the time-travel/MVCC path. HD-P05's '912-927' is the buildHadoopConf METHOD definition, not the planScan call site (the actual call is planScan:147). | Minimum unconditional metaClient builds per pass are ~3-4 (getColumnHandles->getSchemaFromMetaClient :800-801, beginQuerySnapshot->latestInstant :749-750, planScan :148-151, getScanNodeProperties :363), reaching 5-6 with the conditional sites — so '5-6x' is a valid upper bound. HD-P05 substance (buildHadoopConf/storageHadoopConfig built twice per pass at :147 and :363; normalizeNativeUri per-file at :445 and :476) is correct; only the line citation is loose.

Exactly one HudiConnectorMetadata per statement, but it memoizes NOTHING: fields are only {hmsClient:153, properties:154, metaClientExecutor:156, storageHadoopConfig:161} — grep for any HoodieTableMetaClient/InternalSchema/Schema/HoodieTimeline/partition/schema FIELD returns only method signatures, no cache field. Scan provider is a separate object (HudiConnector.getScanPlanProvider returns new HudiScanPlanProvider, :136-138) building its own metaClient in planScan (:148-151) and getScanNodeProperties (:363). + +HOT-PATH FINDINGS — all 5 independently CONFIRMED as real heavy remote-IO ops with genuinely NO memoization (no pre-existing cache catches them): HD-P01 (HoodieTableMetaClient.build reads .hoodie/hoodie.properties + loads active timeline, per line 916-917 comment; rebuilt at every metadata+scan entrypoint), HD-P02 (getTableAvroSchema(true) + resolveTableInternalSchema re-resolved at getSchemaFromMetaClient:819-821, planScan:188/194/220, getScanNodeProperties:382-383), HD-P03 (listAllPartitionPaths = HoodieTableMetadata.create+getAllPartitionPaths at :734-742, no (table,instant) cache), HD-P04 (raw ThriftHmsClient, Variant C — CachingHmsClient exists+used by hive but hudi bypasses it), HD-P05 (buildHadoopConf/storageHadoopConfig 2x + normalizeNativeUri per-file, CPU-only, correctly rated P2). The audit correctly EXCLUDED false positives (per-file schemaIdResolver at :232-241 is genuinely per-file, not a hoistable invariant; format-cache/comment-cache not applicable — getTableType is authoritative at :156, detectFileFormat is a cheap suffix check at :899-910, no getComment override). No severe finding was understated and no finding is covered by an existing cache. Overall verdict (hudi is the least-cached SPI connector; iceberg framework pattern applies and is needed) STANDS. diff --git a/plan-doc/connector-cache-unification/connectors/jdbc.md b/plan-doc/connector-cache-unification/connectors/jdbc.md new file mode 100644 index 00000000000000..24fab9d705b80f --- /dev/null +++ b/plan-doc/connector-cache-unification/connectors/jdbc.md @@ -0,0 +1,90 @@ +## 连接器附录:jdbc(fe-connector-jdbc,catalog type `jdbc`) + +### 结论速览 +`jdbc` 是**关系型透传(relational passthrough)**连接器:FE 只负责元数据发现 + 生成远程 SQL,真正的数据扫描由 BE 的 `JdbcJniReader` 直接对远端库执行。它**没有** iceberg 那套 split / file / manifest / partition / snapshot 规划层,所以 iceberg 热路径缓存框架(cross-query Table/Partition/Format/Manifest cache)对它基本无对应目标。其昂贵远程元数据早已被 **fe-core 跨查询缓存**前置,连接池是 **per-catalog 单例**。审计结论:**不套用 iceberg 式连接器缓存**;只存在两处 P2 级冗余远程取列,适合用轻量 per-statement memo 收口。 + +Migration:`jdbc` ∈ `SPI_READY_TYPES`(`CatalogFactory.java:57`),`JdbcConnectorProvider.getType()=="jdbc"`(`JdbcConnectorProvider.java:41`),经 SPI 路由到 `PluginDrivenExternalCatalog`。legacy fe-core `JdbcExternalCatalog/JdbcExternalTable` 已删;残留 fe-core `datasource/jdbc/client/JdbcClient` 仅服务 CDC/streaming-job 校验,不在 catalog 查询热路径。**LIVE**。 + +### 缓存与记忆一览 + +| 缓存 / 记忆 | 层 | scope | key | TTL / 失效 | file:line | 前置了哪个连接器远程调用 | +|---|---|---|---|---|---|---| +| HikariDataSource 连接池 | 连接器 | cross-query(per-catalog 单例) | 每 client 一池 | connector 生命周期,`close()` 销毁 | `JdbcConnectorClient.java:89` / `JdbcDorisConnector.java:188` | 所有远程 round-trip 的实际资源复用点 | +| CLASS_LOADER_MAP 驱动 classloader | 连接器 | 进程级 cross-query | driver URL | 永不淘汰(986696 Metaspace 泄漏修复) | `JdbcConnectorClient.java:78,268` | 驱动加载 | +| OceanBase compat-mode delegate | 连接器 | cross-query(per-client volatile) | 单 delegate | client 生命周期 | `JdbcOceanBaseConnectorClient.java:45,59` | `ob_compatibility_mode()` 方言探测(一次) | +| ExternalSchemaCache | fe-core | cross-query | `SchemaCacheKey(table)` | expire-after-access + refresh/DDL | `ExternalMetaCacheMgr.java:365` / `ExternalTable.java:447` | `getTableSchema`(via `initSchema`,`PluginDrivenExternalTable.java:469`) | +| ExternalRowCountCache | fe-core | cross-query | `RowCountKey(catalog,db,table)` | expireAfterWrite ~1 天,异步 | `ExternalRowCountCache.java:45` | `getTableStatistics`(via `fetchRowCount`,`:1133`) | +| MetaCache 名录/对象 | fe-core | cross-query | db 名 / (db,table) 名 | expire-after-access + refresh | `metacache/MetaCache.java:65` | `listDatabaseNames`/`listTableNamesFromRemote`(`PluginDrivenExternalCatalog.java:293,310`) | + +**关键事实**:连接器模块(`fe-connector-jdbc`)自身**没有任何元数据缓存**(grep `Cache/memo/Caffeine/LoadingCache` 在连接器代码零命中)。上表前三行是资源/方言单例,后三行是 fe-core 缓存。`JdbcConnectorMetadata` 无状态,每次调用都原样转发 `JdbcConnectorClient` 做一次新的 JDBC 元数据 round-trip(`JdbcConnectorMetadata.java:119/162/144`)。 + +### Funnel 参与 + +- **已 funnel**:所有 fe-core 读 seam 经 `PluginDrivenMetadata.get` 取 metadata(`initSchema:449`、`fetchRowCount:1126`、`getComment:923`、`PluginDrivenScanNode` 的 `metadata()`、`JdbcQueryTableValueFunction:53`)。 +- **metadata 不 memo loaded table**:`JdbcConnectorMetadata` 只持 `client+properties` 引用,`getTableSchema/getColumnHandles/getTableStatistics` 每次都远程取,内部无 memo。JDBC 也**没有**可缓存的昂贵 `Table` 对象。 +- **funnel 对 JDBC 收益有限**:funnel 保证「每语句一个 metadata 实例」,但该实例构造近乎零成本,真正昂贵的连接池已是 per-catalog 单例;funnel 唯一有用之处是提供了一个活的 per-statement scope,可用来 memo `getColumnHandles`——但目前没用上。cross-statement 缓存加载器(`buildCrossStatementSession`,`:1153`)显式用 `ConnectorStatementScope.NONE`,把 schema/rowcount/名录的跨查询缓存契约固化,合理。 + +### 热路径重复取数审计 + +| #

No `[K]` type parameter, identity-sharding dimension, or credential abstraction is added (Rule 2). + +--- + +## A/B/C/D components (revised) + +### A — Generic cross-query cache wrapper (fe-connector-cache) + +**Layer**: `fe/fe-connector/fe-connector-cache`, package `org.apache.doris.connector.cache` (JDK+Caffeine only, verified zero fe-core imports — the fe-core `datasource/metacache/` `CacheSpec`/`MetaCacheEntry` is an independent duplicate this track never touches; iron rule A clean for the whole A track). + +**What is generalized (grounded).** `ConnectorPartitionViewCache[V]` already is the octet iceberg hand-rolls: `new MetaCacheEntry[...](engine + "." + entryName, null, spec, ForkJoinPool.commonPool(), false, true, 0L, true)` (`ConnectorPartitionViewCache.java:70-71`), `matches`/`matchesDb` on the key (`PartitionViewCacheKey.java:66-72`). The five iceberg caches differ only in **key type**, **value type**, and the **db-match predicate**. It hardcodes exactly two axes: `ENTRY_PARTITION_VIEW="partition_view"` and the key class. The manifest cache is **excluded** (path-keyed, no-TTL, default-off, `DataFile`-typed, `authz-cache-exempt` — read only after a per-user `resolveTable`; `IcebergConnector.java:203`). + +**Class shape.** Promote to `ConnectorMetadataCache[V]`: +- **Value stays opaque `[V]`** — load-bearing: values are `String` (comment/format), raw credentialed `org.apache.iceberg.Table` (table-handle), 2-long `CachedSnapshot` (latest-snapshot), `List[…]` (partition). A concrete value type would be useless to a second connector. +- **Key**: rename `PartitionViewCacheKey` → `ConnectorTableKey(db, table, snapshotId, schemaId)` (body already generic; only its name is partition-flavored). Unused axes pass `-1`. One key type for all six cases. +- **Two ctors**: framework-native per-entry (`meta.cache.[engine].[entry].{enable|ttl-second|capacity}`, recommended for hudi/mc/es) **and** pre-resolved `CacheSpec` (so iceberg keeps its single shared `meta.cache.iceberg.table.ttl-second` knob across all five caches — operator back-compat). The `ttl<=0 -> CACHE_TTL_DISABLE_CACHE` mapping that is copy-pasted five times today moves into `CacheSpec.of`/`fromProperties` (already there). +- **Delete `ConnectorPartitionViewCache[V]`** (revision #6). Iceberg/hive/paimon are touched by the rename in PR-1 anyway; have them construct `ConnectorMetadataCache[V]` directly (hive currently does `new ConnectorPartitionViewCache[](\"hive\", props)` at `HiveConnector.java:134` → `new ConnectorMetadataCache[](\"hive\", \"partition_view\", props)`). One type, no inheritance layer for a non-SPI toolkit class. +- **Fix the stale javadoc** `"this class has NO consumers yet"` (`ConnectorPartitionViewCache.java:33`, confirmed false — iceberg `:197,199`, hive `:134`, paimon consume it). +- **Pin legacy telemetry names in the iceberg retrofit** (Review 3 #8): the framework-native ctor derives `name = engine + \".\" + entryName` (→ `iceberg.table`), but iceberg's live entry names are `iceberg-table`, `iceberg-partition`, `iceberg-latest-snapshot`, etc. (`IcebergTableCache.java:70`). The iceberg retrofit MUST pass the exact legacy `name` via the pre-resolved `CacheSpec` ctor so dashboards/log-greps/`*ForTest` accessors don't silently break. + +**Credential policy stays connector-side (iron rule D).** The wrapper is value-opaque and knows nothing about credentials. The connector nulls the field under its gate exactly as today (verified `IcebergConnector.java:231,243,254,260` — `isUserSessionEnabled()`/`restVendedCredentialsEnabled` ternaries): table-handle null when `isUserSessionEnabled() || restVendedCredentialsEnabled`; comment null unless `restVended && !userSession`; format/partition/latest-snapshot null under `isUserSessionEnabled()`. A null field ⇒ `get()` never called ⇒ live bypass. **Trino alignment**: shared low-level toolkit + per-connector caches, no unified cache; we deliberately do NOT port Trino's per-identity `LoadingCache[user,…]` sharding — Doris keeps the binary null-field cut (correct for D1, no connector needs identity keying). + +### B — Statement-scope seam (fe-connector-api ONLY; fe-core untouched) + +**Premise correction (verified).** The memo substrate is already built and already in **fe-connector-api**: `ConnectorStatementScope.computeIfAbsent(key, Supplier)` (`:45`), `ConnectorSession.getStatementScope()` defaulting to `NONE` (`:142`), backed by `ConnectorStatementScopeImpl` (ConcurrentHashMap, idempotent `closeAll`) hung on `StatementContext` (`:209,656`). Iceberg and hudi depend on fe-connector-api and on **neither fe-core nor fe-connector-cache** — a literal fe-core class would be *unreachable* by the retrofit. **The D4 mandate is satisfied with 0 fe-core source lines; iron rule A is not crossed at all.** + +**The seam: one bare static helper + a namespace registry in fe-connector-api** (beside `ConnectorStatementScope`): + +``` +public final class ConnectorStatementScopes { + private ConnectorStatementScopes() {} + // resolve db.table once per statement; keyNamespace namespaces the value TYPE so a heterogeneous + // gateway statement touching two connectors cannot collide on (db,table) -> ClassCastException. + public static [T] T resolveInStatement(ConnectorSession session, String keyNamespace, + String db, String table, Supplier[T] loader) { + if (session == null) { + return loader.get(); // == ConnectorStatementScope.NONE + } + String key = keyNamespace + ":" + session.getCatalogId() + ":" + db + ":" + table + + ":" + session.getQueryId(); + return session.getStatementScope().computeIfAbsent(key, loader); + } +} +``` + +- No new interface, no new type on `ConnectorSession`, no new SPI method — it reuses the existing primitive and standardizes the **security-critical** key convention (dropping `queryId` leaks cross-statement; dropping `catalogId` collides across a cross-catalog MERGE). Centralizing this once is a real correctness win over two connectors re-deriving it (Review 1 #2 grants this). +- **Namespace registry** (Review 3 #7): define the `keyNamespace` constants (`iceberg.table`, `hudi.metaclient`, `maxcompute.handle`, `es.metadata_state`) in one small holder beside `ConnectorStatementScopes`, documented as a reviewed-uniqueness invariant mirroring the existing metadata-funnel key convention (`ConnectorStatementScope.java:51`). `catalogId` already sits inside the key, so two connectors under different catalogs can't collide even on an equal namespace — but the registry prevents same-catalog namespace reuse. + +**Retrofit + consumption:** +- **Iceberg (retrofit)**: `IcebergStatementScope.sharedTable` collapses to `return ConnectorStatementScopes.resolveInStatement(session, \"iceberg.table\", db, table, loader);` — namespace `iceberg.table` reproduces the existing `\"iceberg.table:\"` prefix byte-for-byte, so the funnel sites keep identical hits/misses/`NONE` fallthrough. `rewritableDeleteSupply` stays iceberg-private (a `(catalogId,queryId)`-keyed scan→write delete bridge, not table resolution — out of the seam). **Residual (Review 1 #2): whether to land this retrofit in PR-2 or defer it** — retrofitting audited iceberg widens the diff for no functional gain, but it is also the parity proof. Recommendation: keep it in PR-2 guarded by iceberg's existing memo tests; if the owner wants a narrower blast radius, hudi can be the sole first consumer and iceberg converges later. +- **Hudi (consumes)**: `HoodieTableMetaClient mc = ConnectorStatementScopes.resolveInStatement(session, \"hudi.metaclient\", db, table, () -> buildMetaClient(...))` collapses the ~6 builds/query → 1. Derived `TableSchemaResolver`/Avro/`InternalSchema` compute once off the single memoized client (~4x re-parse → 1). **MANDATORY (Review 3 #5, revision #4)**: memoize a **non-closeable projection** (the resolved schema/timeline snapshot callers need), NOT the raw `HoodieTableMetaClient`, because `closeAll` pass-2 closes every stored `AutoCloseable` at statement end (`ConnectorStatementScopeImpl.java:82`) and hudi is the first connector data-object that may be closeable / hold a `HoodieStorage`/`FileSystem`. This ordering was validated for iceberg's non-closeable `Table`, never for a closeable client. +- **Maxcompute (consumes, B1 only)**: memoize inside `MaxComputeConnectorMetadata.getTableHandle` via `resolveInStatement(session, \"maxcompute.handle\", db, table, …)`. All fan-out sites in `resolveConnectorTableHandle` then hit the connector memo; the remote `exists()` HEAD probe + lazy `get()` fires once. **fe-core untouched. B2 struck.** Precondition verified: `ConnectorSessionBuilder.captureStatementScope()` reads `sc.getOrCreateConnectorStatementScope()` (`:202`), so all in-statement `buildConnectorSession()` calls share one scope instance — B1 genuinely fires. +- **mc claim scoped (Review 1 #5)**: the collapse applies to the in-statement `buildConnectorSession()` subset only; `buildCrossStatementSession()` callers (refresh/cross-statement paths) bind a non-per-statement scope and by design do not share the memo. Do not "fix" them into it. + +**Rule D safety.** The L1 memo is single-identity by construction — a statement resolves one catalog under one identity (`PluginDrivenMetadata` fail-loud pin), scope per-statement + GC'd at end. It never crosses users even when the L2 §A cache is disabled for a vended catalog. + +### C — Authz gate generalization (tools/check-authz-cache-sharding.sh) — REDESIGNED + +> **SUPERSEDED (2026-07-24, owner decision): the gate was REMOVED, not generalized.** Two rounds of adversarial +> clean-room review showed that structurally verifying "this cache is null under session=user" in a shell +> script requires understanding arbitrary Java boolean/multi-line syntax (compound `&&`/`||` guards, multi-line +> lambda loaders, string literals, nested ternaries) — intractable and fragile (false positives break builds on +> legit code; false negatives silently miss leaks). The runtime `IcebergConnectorCacheTest` already proves the +> invariant for the real caches; the gate (`tools/check-authz-cache-sharding.sh` + self-test + the +> `fe-connector/pom.xml` execution) was deleted and replaced by an explicit `ATTN` comment at the iceberg cache +> sites. See [`../progress.md`](../progress.md) "2026-07-24 (5)". The redesign notes below are retained for history only. + +Pure tooling; touches no product source. The original owner-file field-marker scan is **rejected** (Review 2 BLOCKER, Review 3 #3): verified that iceberg holds cache fields on both `IcebergConnector.java` (marked) and `IcebergConnectorMetadata.java:152-171` (unmarked injected), and hive constructs an unmarked cross-query `partitionViewCache` at `HiveConnector.java:134` that the `.contains()` filter excludes from scope. A field-marker gate verifies a comment near a declaration, not the actual null-gate, and is blind to any holder off `*Connector.java`. + +**Redesigned gate — construction-site scan, location-independent:** + +- **Stage 1 — enumerate declaring modules**: `find` all `*Connector.java` under `*/src/main/java/*` (exclude `target/`); keep a module whose `*Connector.java` **declares** the capability via `\.add\([^)]*ConnectorCapability\.SUPPORTS_USER_SESSION` OR `(EnumSet|Set|ImmutableSet)\.of\([^)]*SUPPORTS_USER_SESSION`, after stripping comment lines (`^\s*\*`, `^\s*//`). This admits `IcebergConnector.java:860` (`.add(...)`). +- **Stage 1b — gateway modules in scope (Review 2 major)**: ALSO keep any module whose `*Connector.java` **reads** a sibling capability via `\.getCapabilities\(\)\.contains\([^)]*SUPPORTS_USER_SESSION` — this is the gateway signature (`HiveConnector.java:543`). Gateways delegate to per-user siblings and hold live cross-query caches, so they are in-scope, not excluded. Additionally assert the fail-loud front-door guard is present (the `throw` at `HiveConnector.java:546`); if a gateway reads the sibling capability but lacks the fail-loud assertion, FAIL. +- **Stage 2 — scan construction sites module-wide** (the key change): within each in-scope module, grep ALL `src/main/java` files for construction expressions `new (ConnectorMetadataCache|[A-Za-z_][A-Za-z0-9_]*Cache)[ <(]` (the holder idiom), distinguishing them from injected ctor-param reference fields (which are not `new`). Each construction site must either: + - sit inside a capability null-gate — its assignment RHS is a `isUserSessionEnabled() ? null : new …` (or equivalent capability-gated) ternary — the `authz-cache-session-user-disabled` contract, **now checked at construction, not just as a field comment**; OR + - carry an on-line/line-above `authz-cache-exempt` marker with justification. +- **Stage 3 — hive's `partitionViewCache` (Review 2 major)**: require it to carry an explicit `authz-cache-exempt` marker documenting "front door never declares SUPPORTS_USER_SESSION + fail-loud sibling guard," so the exemption is a reviewed claim, not an invisible gap. (It is unconditionally constructed and unmarked today — `HiveConnector.java:112,134`.) +- **Anti-no-op floor (Review 2, design §C.2)**: if Stage 1+1b yields **zero** in-scope modules, `exit` non-zero — a capability rename or grep drift must fail loud, never silently turn the gate into pass-everything. + +**Self-test additions**: (a) fixture with `.contains(SUPPORTS_USER_SESSION)` + fail-loud guard + an `authz-cache-exempt` cache → PASS (gateway path); (b) same gateway but MISSING the fail-loud guard → FAIL; (c) fixture declaring via `.add`/`EnumSet.of` with a `new …Cache(` constructed unconditionally (no null-gate, no marker) → FAIL (proves construction-site + null-gate check); (d) fixture with a marked field but constructed unconditionally → FAIL (proves the marker-detached-from-guard hole is closed). Keep iceberg as the primary declarer fixture. + +**Scope reality**: today Stage 1 resolves to `{iceberg}` and Stage 1b to `{hive}`; hudi/mc/es have no capability override (verified) and vend static credentials, so their caches are authz-safe without the gate and correctly fall outside it. D3 is **forward-insurance**, orthogonal to D1/D2, and does not block them. The fe-core defense layer (`PluginDrivenExternalCatalog.shouldBypass*Cache`, keyed off runtime `.contains(SUPPORTS_USER_SESSION)`, `:1289`) is already connector-agnostic and needs no change. + +### D — Connector consumption + +**D.1 Hudi (flagship) — consumes B (primary) + A (secondary).** +- **metaClient + schema memo (B)**: route both `HoodieTableMetaClient.builder()` sites through `resolveInStatement(session, \"hudi.metaclient\", …)` — memoizing a **non-closeable schema/timeline projection** (mandatory, §B). `buildMetaClient` reloads the active timeline for freshness, so the per-statement tier is the correct one for the raw client; a cross-query cache of the raw metaClient would be wrong. +- **HMS layer**: hudi is HMS-backed; its metastore access sits behind the shared `CachingHmsClient` (Trino `CachingHiveMetastore` shape, coarse REFRESH+TTL, TCCL-pinned per the `ThriftHmsClient.doAs` memory) exactly as iceberg-on-HMS/hive, so `getTable`/listing round-trips are shared cross-query beneath the per-statement memo. +- **`(table, instant)` partition cache (A) — tension resolved (revision #5, rejecting Review 3 #6's either/or)**: a `ConnectorMetadataCache[List[HudiPartition]]`, `entryName=\"partition\"`, key `ConnectorTableKey(db, table, instant-as-snapshotId, -1)`. **Pin (adopting Review 2 minor + Review 3 #6's fresh requirement)**: the instant MUST be `metaClient.getActiveTimeline().filterCompletedInstants().lastInstant()` (latest *completed*, never inflight/requested), **re-derived fresh each statement** from the statement-scoped metaClient. This is cheap (timeline read); the *expensive* partition-listing is what the cache saves. Cross-query hits occur when the table has not committed between queries (the common case — a stable table's latest-completed-instant is the same value each statement, so the key is identical); a new commit mints a new instant → new key → miss → fresh load. Freshness is therefore preserved AND hit rate is real — Review 3's "near-zero hit rate" holds only for a table committing on every query, which is not the steady state. TTL+REFRESH is the backstop (iron rule E). The cached value is a pure `List[HudiPartition]` projection with **no live metaClient/FileSystem reference** (assert in test). +- **Pom**: add `fe-connector-cache` dependency (absent today) and **verify hudi's shade/assembly self-bundles Caffeine ≥ 2.9.3** — hudi does not receive it transitively as iceberg does via iceberg-core; otherwise the child-loaded `MetaCacheEntry` `NoClassDefFound`s at runtime though it compiles (framework-coherence memory note). +- Iron rules: A honored (all memo/caches connector-side); D honored (hudi vends no per-user credentials, no `SUPPORTS_USER_SESSION`); E honored (instant-in-key + TTL + fresh derivation). + +**D.2 Maxcompute — consumes B only (B1).** +- Memoize `MaxComputeConnectorMetadata.getTableHandle` per statement (`maxcompute.handle`); collapses the ~14–17-site `resolveConnectorTableHandle` fan-out → 1, dropping the redundant remote `tables().exists()` HEAD probe + lazy `tables().get()` to once. Within one resolved handle the ODPS metadata already amortizes (`odpsTable.getSchema()`). +- **No new cross-query cache**: mc already owns `MaxComputePartitionCache` keyed `(db,table)`, constructed on the Connector (`MaxComputeDorisConnector.java:79` — the §C construction-site scan covers it). It uses static AK/SK, declares no `SUPPORTS_USER_SESSION` (verified) → rule-D-compliant as-is, no §A wrapper this round. +- Verify: ODPS static identity confirmed → handle safe to share per-statement (residual: whether it could later be promoted cross-query). Confirm `getTableHandle` has `ConnectorSession` access for the B1 wrap. + +**D.3 Es — consumes B only, must NOT get a cross-query cache (iron rule E).** +- **per-scan hoist of `EsMetadataState` (B)**: `fetchMetadataState` fires 2x/query (planScan + buildScanNodeProperties). Memoize the **mapping/schema half** per statement via `resolveInStatement(session, \"es.metadata_state\", …)` → 1 fetch. Es has no `*Cache` field at HEAD (grep empty), so there is nothing to regress yet — PR-6 introduces the memo. +- **mapping/field-context carrier**: `getTableSchema` discards the raw mapping string `resolveFieldContext` later needs (`EsConnectorMetadata.java:85-93`), forcing ~4 remote `getMapping`/query. Attach the raw mapping to the **statement-scoped `EsMetadataState`** (or `EsTableHandle`), NOT to the generic `ConnectorTableSchema` (must stay connector-agnostic — iron rule B). Collapses ~4 `getMapping` → 1. +- **CRITICAL split (iron rule E)**: `EsMetadataFetcher.fetch()` bundles `fetchMapping()` (reuse-safe) with `fetchShards()` (live shard routing). The memoized `EsMetadataState` carries **only** mapping/field-context; `fetchShards` is **always re-run per statement** and is **never** a cross-query name-keyed cache. Es gets no §A cache. + +--- + +## Sequencing + +Foundation → flagship → two small PRs → gate. Each PR independently landable + verified. + +1. **PR-0 (verification gate, blocks PR-2)** — confirm the prepared-EXECUTE scope lifecycle (Review 3 #4). Verified: `connectorStatementScope` is `StatementContext`-owned with a reset+close path (`StatementContext.java:672-677`) and closes at result return (`:995-996`). **Mechanism correction (2026-07-23 recon):** a prepared `EXECUTE` does NOT get a fresh `StatementContext` — it deliberately *reuses* one across executions (`ExecuteCommand.java:89`). Isolation is provided not by a fresh context but by an explicit `statementContext.resetConnectorStatementScope()` at the top of every `ExecuteCommand.run()` (`ExecuteCommand.java:95`, before all branches) plus a per-retry reset (`StmtExecutor.java:1077`). Recon also confirmed external/connector tables genuinely reach this path (they never take the OLAP short-circuit fast path — that rule matches `logicalOlapScan()` only, `LogicalResultSinkToShortCircuitPointQuery.java:88,97` — so an external-table prepared query always runs the normal `executor.execute()` planner, re-resolving the table each execution). The reset call is therefore reachable and load-bearing, but had NO test proving `ExecuteCommand` invokes it (existing tests cover only the reset primitive). Encode as a **wiring test** that drives `ExecuteCommand.run()` (two EXECUTEs of one prepared stmt must NOT share a memoized table). Cheap; do it before shipping the shared helper. +2. **PR-1 — Generic cache wrapper (fe-connector-cache).** Add `ConnectorMetadataCache[V]` (both ctors); rename `PartitionViewCacheKey` → `ConnectorTableKey`; **delete** `ConnectorPartitionViewCache[V]` and repoint iceberg/hive/paimon to construct `ConnectorMetadataCache[V]` directly; fix the stale javadoc. Pure addition + rename + deletion; no behavior change. Verify: reactor test-compile + existing partition-view tests. +3. **PR-2 — Statement-scope seam (fe-connector-api) + iceberg retrofit.** Add `ConnectorStatementScopes.resolveInStatement` + namespace registry; collapse `IcebergStatementScope.sharedTable` to delegate (byte-identical key). **fe-core: 0 lines. B2 does not exist.** Verify: iceberg per-statement memo tests + full iceberg suite prove cost-invariance. (Residual: defer iceberg retrofit to narrow blast radius — Review 1 #2.) +4. **PR-3 (foundation-first) — Iceberg cache convergence.** Retrofit the five hand-rolled caches onto `ConnectorMetadataCache[V]` via the pre-resolved-`CacheSpec` ctor (shared knob + **pinned legacy names**), keeping connector-side credential null-gates. **Gated on the new `invalidateDb` parity test** (revision #3). Residual #2: now vs later. +5. **PR-4 — Flagship hudi.** Pom dep + Caffeine-bundling verification; metaClient + schema memo via B (**non-closeable projection**); HMS behind `CachingHmsClient`; the `(table, completed-instant, fresh-per-statement)` cross-query partition cache via A; per-scan hoist. **E2E regression required** (heterogeneous + standalone hudi-on-HMS, per the HMS-delegated-capability memory rule), including a concurrent-commit partition-listing test. +6. **PR-5 — Maxcompute (small).** B1 memo inside `getTableHandle`; drop the redundant `exists()` probe. Verify: remote-op call-count on a SELECT. +7. **PR-6 — Es (small).** Per-scan hoist `EsMetadataState` via B; attach raw mapping to statement-scoped state; split `fetch()` so shard routing stays per-statement. Verify: `getMapping` → 1; shard routing re-runs per statement. +8. **PR-7 — Gate generalization (D3, redesigned).** Construction-site module-wide scan + gateway handling + anti-no-op floor + null-gate assertion; extend self-test fixtures. Orthogonal; recommended after PR-1/PR-2 (marker/`*Cache` conventions stable) and before any of hudi/mc/es would declare session=user. + +PR-1 + PR-2 are the foundation and unblock PR-3/4/5/6.

Affects operator surface and any `CacheSpec.applyCompatibilityMap` back-compat for existing mc/es TTL properties. +4. **Comment cache as a first-class entry?** Iceberg builds `commentCache` only for vended catalogs (plain catalogs serve comments from the table-handle cache). None of hudi/mc/es requested a comment cache — leave "comment" per-connector (recommended) rather than modeling it in the wrapper? +5. **MVCC-pin shape.** Keep the pin as opaque `[V]` over the 4-tuple `ConnectorTableKey` with `-1` sentinels (recommended — iceberg `(snapshotId,schemaId)`, paimon single long, hudi instant, mc/es none all fit one key), rather than a fixed 2-axis value type? +6. **Credential-value hardening: contract vs convention.** Keep the current convention (connector nulls the field + §C construction-site null-gate assertion, now enforced) — the smaller design matching today — or add a type/marker contract that makes the wrapper *refuse* credentialed values? Given the redesigned gate now checks the null-gate at construction (R2 closed), convention is likely sufficient; a contract is extra insurance. +7. **Gate strictness + gateway posture.** Hard build FAIL on zero declarers (recommended) — confirmed. And confirm the hive gateway is **in-gate-scope with a required fail-loud-guard assertion** (this design's position, Review 2 major) rather than documented as out-of-scope. +8. **Maxcompute cross-query shareability.** Confirm ODPS uses a static (non-per-user) identity so a resolved handle could later be promoted cross-query — this round it is statement-scoped only (safe default). Verified: mc declares no `SUPPORTS_USER_SESSION`; owner to confirm the identity model for any future promotion. \ No newline at end of file diff --git a/plan-doc/connector-cache-unification/designs/foundation-design-draft.md b/plan-doc/connector-cache-unification/designs/foundation-design-draft.md new file mode 100644 index 00000000000000..d4d078a7961176 --- /dev/null +++ b/plan-doc/connector-cache-unification/designs/foundation-design-draft.md @@ -0,0 +1,259 @@ +Verification confirms the load-bearing recon claims: `ConnectorStatementScope.computeIfAbsent` lives in fe-connector-api (not fe-core); `ConnectorPartitionViewCache[V]` + `PartitionViewCacheKey(db,table,snapshotId,schemaId)` already exist with the exact contextual-only MetaCacheEntry octet; the "NO consumers yet" javadoc is confirmed stale (iceberg, hive, paimon all wire it — IcebergConnector.java:281,284, HiveConnector.java:134, PaimonConnector.java:158); and the gate hardcodes `TARGET_REL` to IcebergConnector.java with the `FIELD_DECL` + two-marker logic.

Generalizing = promote it to `ConnectorMetadataCache[V]` with an `entryName` ctor arg + a neutral key name. Iceberg retrofits with zero behavior/cost change; hudi/mc/es instantiate typed copies. + +- **(B) The D4 seam does NOT need to grow fe-core.** The per-statement memo arena (`ConnectorStatementScope.computeIfAbsent`, `ConnectorSession.getStatementScope()`, backed by `ConnectorStatementScopeImpl` on `StatementContext`) is **already complete and already connector-agnostic, and lives in fe-connector-api** — which iceberg and hudi depend on, and fe-core does **not**. Iceberg's only connector-private piece is a 9-line key-convention wrapper (`IcebergStatementScope.sharedTable`). The minimal D4 seam is a single static convenience helper in fe-connector-api that standardizes that key convention. This means **iron rule A is not actually crossed** — the sanctioned fe-core exception can be declined. This is the #1 residual owner decision. + +- **(C) The gate generalization** is a discovery change, not a new mechanism: replace the hardcoded `TARGET_REL` with a two-stage scan (enumerate `*Connector.java`, keep only files whose `getCapabilities()` *declares* `SUPPORTS_USER_SESSION` via `.add(...)`/`EnumSet.of(...)`, excluding `.contains(...)` guards and comments), then run the existing field+marker logic verbatim on each. Today it resolves to exactly `{iceberg}`, so behavior is unchanged and immediately testable. + +- **(D) Consumption**: hudi (flagship) consumes both B (metaClient + schema memo per statement — the ~6x/~4x redundancy) and A (a `(table, instant)` cross-query partition cache); maxcompute consumes B (collapse the 14–17-site `getTableHandle` fan-out, killing the repeated remote `exists()` probe) — it already has a cross-query partition cache; es consumes B only (per-scan hoist of `EsMetadataState`, split mapping from shard routing), and must **not** get a cross-query cache (iron rule E). + +- **(E) Sequencing** is foundation-first: cache wrapper PR → api seam PR (+ iceberg retrofit, proven by existing tests) → flagship hudi PR (with e2e) → small mc PR → small es PR → gate PR (orthogonal, land any time). + +The design deliberately targets **only the two real cross-query consumers (iceberg + hudi)** plus the two per-statement-only consumers (mc + es).

Generic cache wrapper (fe-connector-cache) + +### A.1 What is being generalized (grounded) + +The five iceberg cross-query caches (`IcebergTableCache`, `IcebergLatestSnapshotCache`, `IcebergPartitionCache`, `IcebergFormatCache`, `IcebergCommentCache`) each construct the identical contextual-only entry — `new MetaCacheEntry[...]("iceberg-", null, spec, ForkJoinPool.commonPool(), false, true, 0L, true)` — expose `getOrLoad(key, Supplier)` = `entry.get(key, ignored -> loader.get())`, `isEnabled()` = `entry.stats().isEffectiveEnabled()`, and `invalidate`/`invalidateDb`/`invalidateAll` via `invalidateKey`/`invalidateIf`/`invalidateAll`. They differ only in **key type**, **value type**, and the **db-match predicate**. `ConnectorPartitionViewCache[V]` (fe-connector-cache) already captures this exact shape for one case, keyed by `PartitionViewCacheKey(db, table, snapshotId, schemaId)` with `matches`/`matchesDb` predicates on the key — and is already a live consumer in iceberg/hive/paimon. It hardcodes exactly two axes: `ENTRY_PARTITION_VIEW = "partition_view"` (the property namespace + entry name) and the key class. + +The manifest cache is explicitly **excluded** — it is path-keyed, no-TTL, default-off, iceberg-`DataFile`-typed, authz-exempt (read only after a per-user `resolveTable`), and carries a per-scan `ScanStats` stash. It is not a cross-query generalization target. + +### A.2 Generic class shape + +**Layer**: fe-connector-cache, package `org.apache.doris.connector.cache` (the connector-side copy — JDK+Caffeine only, zero fe-core deps; NOT fe-core's `datasource/metacache`). + +Promote `ConnectorPartitionViewCache[V]` to a general `ConnectorMetadataCache[V]`: + +``` +public final class ConnectorMetadataCache[V] { + private final MetaCacheEntry[ConnectorTableKey, V] entry; + + // Framework-native ctor: per-entry namespace meta.cache...(enable|ttl-second|capacity) + public ConnectorMetadataCache(String engine, String entryName, Map[String,String] props) { + CacheSpec spec = CacheSpec.fromProperties( + props == null ?

Unused axes pass `-1`. Every one of the five iceberg caches maps onto it: + - table-handle / comment / latest-snapshot: `(db, table, -1, -1)` + - file-format: `(db, table, snapshotId, -1)` + - partition (raw): `(db, table, snapshotId, -1)` + - partition-view (existing): `(db, table, snapshotId, schemaId)` + + This is one key type for all six. Iceberg's caches currently key by `TableIdentifier` / composite `(TableIdentifier, snapshotId)`; retrofit swaps them to `ConnectorTableKey`, functionally identical (a `TableIdentifier` is `db.table`). + +- **Value**: stays **opaque `[V]`**. This is load-bearing: `comment`/`file-format` are `String`, but `table-handle` is a raw `org.apache.iceberg.Table` (credentialed), `latest-snapshot` is a 2-long `CachedSnapshot`, `partition` is `List[IcebergRawPartition]`. A wrapper that owned a concrete value type would be useless to any second connector. Opaque `[V]` serves all. + +- **Config — expose BOTH styles**: the framework-native per-entry ctor (`meta.cache...*`, recommended for hudi/mc/es) **and** the pre-resolved `CacheSpec` ctor so iceberg keeps its single shared knob `meta.cache.iceberg.table.ttl-second` across all five caches (operator back-compat). This also retires the `ttl<=0 -> CACHE_TTL_DISABLE_CACHE` mapping that is copy-pasted five times today (it moves into `CacheSpec.of`/`fromProperties`, already there). + +- Keep the existing `ConnectorPartitionViewCache[V]` as a 3-line thin subclass/factory that calls the new ctor with `entryName="partition_view"`, so its three current consumers (iceberg/hive/paimon) are untouched byte-for-byte. **Fix the stale "NO consumers yet" javadoc** (confirmed false at HEAD). + +### A.3 How iceberg is retrofitted without behavior/cost change + +Delete the five hand-rolled cache classes; replace each field with a typed `ConnectorMetadataCache[V]` built from the **same pre-resolved `CacheSpec`** iceberg already derives from `resolveTableCacheTtlSecond` (default 86400, capacity 1000). Because the octet, the loader wiring, the `isEffectiveEnabled` gate, and the invalidation semantics are identical, cache hits/misses/eviction are unchanged; existing iceberg cache tests (`*ForTest` accessors, `loadCountForTest`) prove invariance. + +**Iron rule D at the fault line**: the wrapper stays value-opaque and **knows nothing about credentials**. The credential policy stays exactly where it is today — in the *connector*, which nulls the field under its gate: +- table-handle: null when `isUserSessionEnabled() || restVendedCredentialsEnabled(props)` (stricter, because the value carries FileIO credentials). +- comment: null unless `restVendedCredentialsEnabled && !isUserSessionEnabled()`. +- format/partition/latest-snapshot: null under `isUserSessionEnabled()`. + +A null field ⇒ `get()` never called ⇒ live bypass (exactly today's behavior). The wrapper never needs a credential flag; the gate script (§C) enforces the marker on the field declaration. + +- **Layer**: fe-connector-cache (connector-side, child-loaded). **Iron-rule impact**: none on A — fe-core source does not grow; the new memo is connector-side (rule A honored); the class holds no property parsing beyond `CacheSpec.fromProperties`, which already lives here (rule C honored). +- **Trino alignment**: matches Trino's "shared low-level toolkit (`io.trino.cache`), per-connector caches, NO single unified cache." **Divergence**: we do not port Trino's per-identity `LoadingCache[user, ...]` sharding — Doris keeps the binary enable/disable (null field) cut, which is correct for D1 (no connector needs identity keying). +- **Consumers**: iceberg (retrofit, 5 caches), hudi (`(table,instant)` partition cache), and — if they ever add a cross-query cache — mc/es. Not needed by es this round (rule E). + +--- + +## B. Minimal fe-core statement-scope seam + +### B.1 The premise correction + +D4 was framed as extracting a **fe-core** seam that crosses iron rule A. Recon (unanimous across agents, verified above) shows the substrate is **already built and already in fe-connector-api**: + +- `ConnectorStatementScope.computeIfAbsent(String key, Supplier[T])` — the whole memo primitive, opaque `Object` values under string keys; `NONE` runs the loader every call (fe-connector-api). +- `ConnectorSession.getStatementScope()` — neutral access point, defaults to `NONE` (fe-connector-api). +- `ConnectorStatementScopeImpl` (ConcurrentHashMap, two-pass idempotent `closeAll`) hung on `StatementContext` with per-execution reset — **already in fe-core, needs zero change**. +- Iceberg's only connector-private code is `IcebergStatementScope.sharedTable(session, db, table, Supplier[Table])`: null-session ⇒ load; else key = `"iceberg.table:" + catalogId + ":" + db + ":" + table + ":" + queryId` ⇒ `computeIfAbsent`. +- Iceberg and hudi both depend on **fe-connector-api**, and on **neither fe-core nor fe-connector-cache** (a literal fe-core class would be unreachable by the retrofit; fe-connector-cache has no dep on ConnectorSession). + +### B.2 The seam: one static helper in fe-connector-api + +**Layer**: fe-connector-api, beside `ConnectorStatementScope` (connector-side SPI module). + +``` +public final class ConnectorStatementScopes { + private ConnectorStatementScopes() {} + + /** Resolve db.table once per statement and share the one object across every resolver. + * keyNamespace namespaces the value TYPE so a heterogeneous gateway statement touching + * two connectors cannot collide on the same (db,table) and hit a ClassCastException. */ + public static [T] T resolveInStatement(ConnectorSession session, String keyNamespace, + String db, String table, Supplier[T] loader) { + if (session == null) { + return loader.get(); // == ConnectorStatementScope.NONE + } + String key = keyNamespace + ":" + session.getCatalogId() + ":" + db + ":" + table + + ":" + session.getQueryId(); + return session.getStatementScope().computeIfAbsent(key, loader); + } +} +``` + +This adds **no new interface, no new type on the SPI, no fe-core source** — it reuses the existing `computeIfAbsent` primitive and standardizes the key convention iceberg hand-rolls. `keyNamespace` is a **required** parameter (not a hardcoded prefix): it both reproduces iceberg's exact existing key and prevents cross-connector value-type collisions in a gateway statement. + +### B.3 Retrofit + consumption + +- **Iceberg (retrofit)**: `IcebergStatementScope.sharedTable` collapses to `return ConnectorStatementScopes.resolveInStatement(session, "iceberg.table", db, table, loader);` — byte-identical key (namespace `"iceberg.table"` reproduces the `"iceberg.table:"` prefix), so the 4 funnel sites (`resolveTableForRead:646`, scan `:2360`, write `:704`, txn `:212`) keep identical hits/misses and `NONE` fallthrough. `rewritableDeleteSupply` stays iceberg-private (it is a `(catalogId, queryId)`-keyed scan→write delete bridge, not a table resolution, and is **out of the seam**). +- **Hudi (consumes)**: wrap the metaClient build — `HoodieTableMetaClient mc = ConnectorStatementScopes.resolveInStatement(session, "hudi.metaclient", db, table, () -> buildMetaClient(...));` — collapsing the ~6 builds/query to 1. Hudi has no per-statement memo today (two independent `HoodieTableMetaClient.builder()` sites), so this is a clean new consumer. Derived state (`TableSchemaResolver`/Avro/`InternalSchema`) is then computed once off the single memoized metaClient, killing the ~4x re-parse. Hudi needs **no new module dependency** for the seam (already depends on fe-connector-api). + +### B.4 The sanctioned fe-core exception (only if the owner insists / for the mc fan-out) + +The maxcompute redundancy is a *fe-core artifact*: `PluginDrivenExternalTable.resolveConnectorTableHandle` (fe-core:116) calls `metadata.getTableHandle` fresh at 14–17 sites. Two placements collapse it: + +- **B1 (recommended, fe-core flat)**: memoize *inside* the connector's `getTableHandle` via `resolveInStatement(session, "maxcompute.handle", db, table, ...)`. All 14–17 fe-core calls then hit the connector's per-statement memo; the remote `exists()`+`get` fires once. fe-core untouched. +- **B2 (sanctioned D4 exception, generic)**: wrap the one fe-core call site in the *existing* primitive — `session.getStatementScope().computeIfAbsent("tablehandle:" + catalogId + ":" + db + ":" + remoteName + ":" + queryId, () -> metadata.getTableHandle(...))`. This is the **smallest possible reading** of the sanctioned exception: **no new fe-core type, no new SPI method** — just a memoized call site reusing `computeIfAbsent`, benefiting every connector (including non-migrated ones) uniformly. fe-core source grows by ~3 lines in an existing method. + +**Recommendation**: use **B1** for the two named seam consumers (iceberg + hudi resolve raw `Table`/metaClient objects connector-side). Use **B2** for maxcompute if the owner wants the generic fan-out collapsed without touching mc's `getTableHandle` — mc is the connector that most justifies the sanctioned exception, and even then it costs zero new SPI surface. + +- **Iron-rule impact**: B1 = none (rule A intact). B2 = the sanctioned minimal exception, ~3 lines, reusing an existing primitive. +- **Trino alignment**: this recreates, at *statement* granularity, Trino's per-*transaction* "load each table once / read+write share one metadata." **Divergence**: Doris's unit is the statement (scope keyed by queryId, reset per prepared EXECUTE), so nothing may assume cross-statement reuse. +- **Rule D safety**: the L1 memo is single-identity by construction — a statement resolves one catalog under one identity (`PluginDrivenMetadata` fail-loud pin), scope is per-statement + GC'd at end. So the memo never crosses users even when L2 (the §A cross-query cache) is disabled for a vended catalog. **Lifecycle caveat for hudi**: `ConnectorStatementScopeImpl.closeAll` closes any stored `AutoCloseable` at statement end; if a hudi version's `HoodieTableMetaClient` (or a wrapper) is `AutoCloseable`/holds a `HoodieStorage`/`FileSystem`, verify auto-close-at-statement-end is desired, else memoize a non-closeable projection. +- **Consumers**: iceberg (retrofit), hudi (metaClient), maxcompute (handle, B1 or B2), es (metadata state, §D). + +--- + +## C. Authz gate generalization + +**Layer**: `tools/check-authz-cache-sharding.sh` + its self-test — pure tooling, touches no product source (rule A trivially honored). Wired at fe-connector reactor `validate` phase with `${project.basedir}` as root (already reaches all connector modules; no pom change). + +### C.1 The change: discovery replaces the hardcoded target + +Replace `TARGET_REL='fe-connector-iceberg/.../IcebergConnector.java'` with a three-stage scan: + +- **Stage 1 — enumerate**: `find "${ROOT}" -path '*/src/main/java/*' -name '*Connector.java'` (excluding `target/`). +- **Stage 2 — filter to declarers**: keep a file only if it **declares** the capability, matching the declaration form and excluding references/comments: + - INCLUDE lines matching `\.add\([^)]*ConnectorCapability\.SUPPORTS_USER_SESSION` OR `(EnumSet|Set|ImmutableSet)\.of\([^)]*SUPPORTS_USER_SESSION` + - after stripping comment lines (`^\s*\*`, `^\s*//`) and **excluding** any line containing `.contains(`. + + This is the single load-bearing distinction: it admits `IcebergConnector.java:860` (`capabilities.add(...SUPPORTS_USER_SESSION)`) and rejects `HiveConnector.java:543` (`sibling.getCapabilities().contains(...SUPPORTS_USER_SESSION)` — a fail-loud guard, not a declaration) and the fe-connector-api javadoc mentions. A static grep does **not** try to evaluate iceberg's `if (isUserSessionEnabled())` runtime guard — any source-level `.add` means the connector *can* carry the capability, so its caches are in scope unconditionally (correct conservative altitude). +- **Stage 3 — classify verbatim**: run the **existing** `FIELD_DECL='final ([A-Za-z_][A-Za-z0-9_]*)?Cache[ <]'` + two-marker (`authz-cache-session-user-disabled` / `authz-cache-exempt`, on-line-or-line-above) logic on each declaring file. No change to marker vocabulary or RED/GREEN semantics — iceberg keeps passing unchanged, and the existing self-test stays valid. + +### C.2 Invariants and guards + +- **Scan the OWNER file only** (`*Connector.java`), never the whole module: the constructor-injected reference fields in `*ConnectorMetadata`/`*ScanPlanProvider` are unmarked *by design*; a whole-module scan would false-positive on all of them. State this as an explicit invariant. +- **Anti-no-op floor**: if Stage 2 yields **zero** declarers, `exit` non-zero (mirroring today's `exit 2` for missing target). Without this, a capability rename or grep drift silently turns the gate into pass-everything — the highest-risk failure of any discovery gate. +- **Self-test additions**: (a) a fixture connector with a `.contains(SUPPORTS_USER_SESSION)` guard + comment + an unmarked cache field MUST NOT be scanned (proves REFERENCE excluded); (b) a second fixture that DECLARES via `.add`/`EnumSet.of` with an unmarked cache MUST fail (proves multi-connector discovery). Keep the iceberg fixture as the primary declarer. + +### C.3 Scope reality + +Today only iceberg declares the capability; hudi/mc/es have no `getCapabilities` override and vend static (not per-user) credentials, so their new caches are authz-safe **without** the gate and correctly fall outside it (rule D). D3 is therefore **forward-insurance**: it changes behavior for exactly one connector now (no-op vs iceberg) but auto-enrolls any future session=user adopter before an unguarded cross-query cache can leak. It is **orthogonal** to D1/D2 and does not block them. Documented residual: whether the hive-gateway path (a sibling could declare the capability, guarded at `HiveConnector.java:543`) is in-gate-scope or explicitly out (the front door never declares it). + +Note: the fe-core defense layer (`PluginDrivenExternalCatalog.shouldBypass{TableName,DbName,Schema}Cache`, keyed off `getCapabilities().contains(SUPPORTS_USER_SESSION)` at runtime) is **already** connector-agnostic and needs no change — it auto-covers any future declarer. The gate only closes the connector-side hole where a new `*Cache` field is added and forgotten. + +--- + +## D. Connector consumption (hudi / maxcompute / es) + +### D.1 Hudi (flagship) — consumes B (primary) + A (secondary) + +- **metaClient + schema memo (B)**: route both `HoodieTableMetaClient.builder()` sites through `resolveInStatement(session, "hudi.metaclient", db, table, () -> buildMetaClient(...))`. Collapses ~6 builds → 1/statement and, since `TableSchemaResolver`/Avro/`InternalSchema` are derived off the single memoized client, ~4 schema re-parses → 1. This is the flagship win, and the **per-statement** tier is the correct one: `buildMetaClient` reloads the active timeline for freshness, so a cross-query cache of the raw metaClient would be wrong; the per-statement memo is exactly right. +- **Wrap `CachingHmsClient`**: hudi is HMS-backed (depends on fe-connector-hms/metastore-hms). Its HMS access should sit behind the shared `CachingHmsClient` (Trino `CachingHiveMetastore` shape, coarse REFRESH+TTL, TCCL-pinned per the memory notes on `ThriftHmsClient.doAs`) exactly as iceberg-on-HMS and hive do — so metastore round-trips (`getTable`, listing) are shared cross-query at the HMS layer, beneath the per-statement metaClient memo. +- **`(table, instant)` partition cache (A)**: a `ConnectorMetadataCache[List[HudiPartition]]` with `entryName="partition"`, key `ConnectorTableKey(db, table, instant-as-snapshotId, -1)`. The instant (commit time) is hudi's MVCC coordinate, so pinning it into the key makes the cache always-correct (rule E: new instant ⇒ new key; plus bounded TTL + REFRESH invalidation). This is the secondary, TTL-bounded win — build it after the per-statement memo. +- **per-scan hoist**: the two scan-planning sites reuse the single memoized metaClient/schema via B. +- **Pom**: add `fe-connector-cache` dependency (currently absent). **Verify** hudi's assembly/shade bundles **Caffeine ≥ 2.9.3** — hudi does not receive it transitively the way iceberg does via iceberg-core; otherwise the child-loaded `MetaCacheEntry` `NoClassDefFound`s at runtime though it compiles (per the framework-coherence memory note). +- **Iron rules**: A honored (all new memo/caches connector-side); D honored (hudi vends no per-user credentials, no `SUPPORTS_USER_SESSION`, so the `(table,instant)` name-keyed cache needs no per-user disabling); E honored (instant in key + TTL). **Trino**: mirrors Trino keeping the fresh per-transaction view (timeline) distinct from the long-lived metastore cache. + +### D.2 Maxcompute — consumes B only + +- **per-metadata handle memo (B)**: the seam target is `resolveConnectorTableHandle`'s 14–17-site fan-out (recon corrects the report's "10"). Use **B1** (wrap `MaxComputeConnectorMetadata.getTableHandle` in `resolveInStatement(session, "maxcompute.handle", db, table, ...)`) or the sanctioned **B2** (memoize the fe-core call site). Either collapses to one `getTableHandle`/statement, which **drops the redundant remote `tables().exists()` HEAD probe + lazy `tables().get()`** to once. Within one resolved handle the ODPS metadata already amortizes (`odpsTable.getSchema()` reused by schema/columns/scan); the fan-out is the only leak. +- **No new cross-query cache**: maxcompute already owns a cross-query `MaxComputePartitionCache` keyed `(db, table)` (owned in the Connector, so the §C owner-file scan covers it). It uses a static AK/SK identity and does not declare `SUPPORTS_USER_SESSION` — so it is rule-D-compliant as-is and needs no §A wrapper this round. +- **Verify**: ODPS uses a static (not per-user) identity, so the resolved handle is safe to share per-statement (and would even be cross-query-safe) — confirm before treating it as shareable (rule D). Confirm `getTableHandle` has `ConnectorSession` access for the B1 wrap. +- **Iron rules**: A honored (B1) or sanctioned-minimal (B2); D honored. **Trino**: same "resolve once per unit" as iceberg. + +### D.3 Es — consumes B only, must NOT get a cross-query cache + +- **per-scan hoist of `EsMetadataState` (B)**: `fetchMetadataState` fires 2x/query (planScan + buildScanNodeProperties). Memoize the **mapping/schema half** per statement via `resolveInStatement(session, "es.metadata_state", db, table, ...)` → 1 fetch. +- **mapping/field-context carrier**: `getTableSchema` currently discards the raw mapping string that `resolveFieldContext` later needs (`EsConnectorMetadata.java:85-93`), forcing ~4 remote `getMapping` calls/query. Attach the raw mapping to a **statement-scoped `EsMetadataState`** (or the `EsTableHandle`), not to the generic `ConnectorTableSchema` (which must stay connector-agnostic — rule B). `resolveFieldContext` then reuses it, collapsing ~4 `getMapping` → 1. +- **CRITICAL split (rule E)**: `EsMetadataFetcher.fetch()` currently bundles `fetchMapping()` (reuse-safe) with `fetchShards()` (live shard routing). The reuse layer may memoize the **mapping** within a statement but **shard routing must stay per-statement fresh and must NEVER be a cross-query name-keyed cache**. So the memoized `EsMetadataState` carries only mapping/field-context; `fetchShards` is always re-run. Es gets **no §A cross-query cache**. +- **Iron rules**: A honored (state connector-side); B honored (raw mapping rides the handle/state, not the generic schema); E honored (shard routing stays per-statement). **Trino**: mirrors Trino keeping `CachingDirectoryLister`/shard state as a fresh per-transaction layer distinct from the metadata cache. + +--- + +## E. Sequencing + +Foundation first, then flagship, then the two small PRs, then the gate. Each PR is independently landable and independently verified. + +1. **PR-1 — Generic cache wrapper (fe-connector-cache).** Add `ConnectorMetadataCache[V]` (both ctors); rename `PartitionViewCacheKey` → `ConnectorTableKey` (mechanical, updates iceberg/hive/paimon imports); make `ConnectorPartitionViewCache[V]` a thin `entryName="partition_view"` specialization; **fix the stale javadoc**. Pure addition + rename; no behavior change.

Verify: iceberg's existing per-statement memo tests + full iceberg suite prove cost-invariance. **This is where the owner's D4 decision is exercised** — land it as the fe-connector-api helper (rule A intact); only if the owner insists on the literal fe-core exception, add the B2 memoized call site as a separate, clearly-flagged commit. + +3. **PR-3 (optional, foundation-first) — Iceberg cache convergence.** Retrofit iceberg's five hand-rolled caches onto `ConnectorMetadataCache[V]` using the pre-resolved-`CacheSpec` ctor (shared `table.ttl-second` knob), keeping the connector-side credential null-gates.

Orthogonal — can land any time, but recommended **after PR-1/PR-2** so the marker contract and `*Cache` type convention are stable, and **before** hudi/mc/es would ever declare session=user. + +PR-1 and PR-2 are the foundation and unblock everything. PR-4/5/6 depend on both. PR-7 is independent. + +--- + +## Risks + +- **Iceberg retrofit re-touches audited caches.** Converging the five caches (PR-3) widens the diff over previously-audited code. Mitigation: the octet + `CacheSpec` + invalidation are provably identical; gate on existing `*ForTest`/`loadCountForTest` assertions; keep the shared-knob ctor so operator-facing config is byte-identical. If the owner prefers a narrower blast radius, PR-3 can be deferred and iceberg's five caches left as-is (they already work), with `ConnectorMetadataCache` used only by new consumers — but that forgoes the foundation-first convergence the mandate asks for. +- **Hudi Caffeine bundling.** Compiles but `NoClassDefFound`s at runtime if the hudi assembly doesn't self-carry Caffeine ≥ 2.9.3. Mitigation: verify hudi's shade/assembly config (not just ``) and add an explicit Caffeine dep if not transitively present; smoke-test with a redeploy. +- **Hudi metaClient lifecycle in the statement scope.** If a hudi version's `HoodieTableMetaClient` (or a memoized wrapper) is `AutoCloseable`/holds a `FileSystem`/`HoodieStorage`, `closeAll` auto-closes it at statement end — desirable only if nothing outside the statement retains it. Mitigation: verify per hudi version; if not, memoize a non-closeable projection, not the client. +- **Gate discovery drift → silent no-op.** A capability rename or grep-form change could empty the declarer set. Mitigation: the anti-no-op floor (`exit` non-zero on zero declarers) + the two new self-test fixtures. +- **Es shard-routing regression.** Any reuse layer that accidentally memoizes `fetchShards` output cross-query (or even reuses stale routing across a statement in a way that misroutes) breaks correctness. Mitigation: the memoized `EsMetadataState` must, by construction, hold only mapping/field-context; keep `fetchShards` a separate always-fresh call; assert routing re-runs. +- **Cross-connector key collision in a gateway statement.** Two connectors memoizing the same `(db, table)` under the same namespace would collide on the opaque `Object` and `ClassCastException`. Mitigation: `keyNamespace` is a required, connector-distinct parameter in `resolveInStatement` (and the §A cache is per-connector-instance, so no cross-connector sharing there). +- **Credential leak via a future generic cache.** If a future connector caches a credentialed value under only the session=user gate, the name-keyed cache could leak (list≠load). Mitigation: the wrapper stays value-opaque and the credential gate stays in the connector (null the field); the §C gate enforces the marker on every `*Cache` field. Residual: whether to harden this from convention to a type/marker contract (see below). + +--- + +## Residual owner decisions + +1. **D4 placement (highest priority).** Recon shows the reachable home for the seam is **fe-connector-api**, not fe-core — iceberg/hudi cannot depend on fe-core, and the memo primitive already exists there. Do you accept re-reading "fe-core seam" as "fe-connector-api helper" (`ConnectorStatementScopes.resolveInStatement`), leaving **fe-core source flat and iron rule A untouched**? If you still want the literal fe-core exception, its minimal form is the B2 memoized call site in `resolveConnectorTableHandle` — **zero new fe-core type, ~3 lines reusing the existing `computeIfAbsent`** — used chiefly to collapse maxcompute's fan-out generically. (Recommendation: fe-connector-api helper for iceberg+hudi; B2 only if you want mc's fan-out collapsed without touching the mc connector.) + +2. **Iceberg cache convergence now vs later (PR-3).** Retrofit all five iceberg caches onto `ConnectorMetadataCache` this round (foundation-first, max convergence, wider diff over audited code) — or add the generic class for new consumers only and leave iceberg's five as-is (narrower, less convergence)? + +3. **Config namespace for hudi/mc/es caches.** Framework-native per-entry knobs (`meta.cache...*`, recommended) or a single shared per-catalog knob like iceberg's `table.ttl-second`? Affects operator surface and any back-compat mapping (`CacheSpec.applyCompatibilityMap`) for existing mc/es TTL properties. + +4. **Comment cache as a first-class entry?** Iceberg builds `commentCache` only for vended catalogs because plain catalogs serve the comment path from the table-handle cache. Do hudi/mc/es have a table-handle cache to piggyback, or does each need a standalone comment path? Decides whether the wrapper models "comment" as a first-class entry or leaves it per-connector. (Given D1 scope, likely leave per-connector — none of hudi/mc/es requested a comment cache.) + +5. **Latest-snapshot / MVCC-pin shape.** Iceberg's pin is `(snapshotId, schemaId)`, paimon's is a single long, hudi's is an instant, mc/es have no snapshot axis. Keep the pin as opaque `[V]` over the 4-tuple key (recommended — one key, `-1` sentinels) rather than a fixed 2-axis value type? + +6. **Credential-value hardening: contract vs convention.** Should the wrapper *refuse* credentialed values by a type/marker constraint, or keep the current convention (connector nulls the field under its gate + the §C marker enforces it)? Convention is the smaller design and matches today; a contract is insurance against a future connector caching a credentialed value under only the session=user gate. + +7. **Gate strictness on empty declarer set.** Hard build FAIL (recommended) vs warning when Stage 2 finds zero declarers? And is the hive-gateway sibling path (guarded at `HiveConnector.java:543`) in-gate-scope or explicitly documented as out? + +8. **maxcompute cross-query shareability.** Confirm ODPS uses a static (non-per-user) identity so a resolved handle is safe beyond a single statement — this decides whether mc's handle memo may be statement-scoped only (safe default) or could later be promoted cross-query (rule D). \ No newline at end of file diff --git a/plan-doc/connector-cache-unification/designs/review-1.md b/plan-doc/connector-cache-unification/designs/review-1.md new file mode 100644 index 00000000000000..e819e400f59420 --- /dev/null +++ b/plan-doc/connector-cache-unification/designs/review-1.md @@ -0,0 +1,103 @@ +I have enough grounding.

The design is buildable, but several parity/portability claims are overstated. Objections most-severe-first. + +--- + +## 1. [blocker — for the B2 variant] The sanctioned fe-core exception (B2) memoizes `getTableHandle` for EVERY connector, not just maxcompute + +**Issue.** §B.4-B2 and PR-5 wrap the *generic* fe-core funnel `PluginDrivenExternalTable.resolveConnectorTableHandle` (fe-core) in `computeIfAbsent`. That funnel is the single site all connectors flow through. Memoizing it changes the call-count contract of `getTableHandle` for jdbc/paimon/trino/hive/iceberg — every connector outside this round's D1 scope and outside its test coverage. + +**Reasoning.** The design frames "benefits every connector uniformly" (§B.4-B2) as an advantage, but that is precisely the parity hazard: today `resolveConnectorTableHandle` is called fresh at 14–17 sites, and any connector that relies on that — a remote `exists()` probe used as a liveness/authorization check, a freshness re-read, a side-effecting handle build — silently loses those repeats. You cannot assert parity for connectors you are not testing this round. This also sits at the exact fault line of iron rule A (fe-core grows) with an unbounded blast radius, which is the opposite of "minimal sanctioned exception." + +**Fix.** Drop B2. Use **B1 (connector-local memo inside `MaxComputeConnectorMetadata.getTableHandle`)** for maxcompute too — it collapses the same fan-out with zero fe-core growth and zero cross-connector reach. If the owner insists on a fe-core site, scope it so only the maxcompute path is memoized (e.g. gate on the connector already opting in), never the shared funnel unconditionally. The design's own recommendation already leans B1; make it the only option. + +--- + +## 2. [major] Iceberg retrofit is NOT byte-identical: it changes db-invalidation from iceberg `Namespace` equality to plain `String` equality + +**Issue.** §A.2/§A.3 claim the retrofit onto `ConnectorTableKey(db,table,…)` is "functionally identical (a `TableIdentifier` is `db.table`)." But four of the five caches key by `TableIdentifier` and invalidate a db via **iceberg Namespace equality**, not string equality: +- `IcebergTableCache.java:102-103`: `Namespace ns = Namespace.of(dbName); entry.invalidateIf(id -> id.namespace().equals(ns))` +- same in `IcebergLatestSnapshotCache.java:108-110`, `IcebergPartitionCache.java:121-123`, and format cache. + +`ConnectorTableKey`/`PartitionViewCacheKey` invalidate via `Objects.equals(this.db, db)` (`PartitionViewCacheKey.java:71-73`). + +**Reasoning.** For single-level namespaces these coincide, but the retrofit relocates db extraction from "iceberg's `Namespace` object at invalidation time" to "a `String db` frozen into the key at build time." That diverges for any multi-level namespace, and it moves a piece of iceberg-specific identity logic into the generic key construction — exactly the kind of silent semantic drift on already-audited, already-shipped code the mandate says to avoid. "Same cache keys, same call counts" is not established for the invalidateDb path. + +**Fix.** Before PR-3, add an explicit parity test that `invalidateDb` on the retrofitted key evicts exactly the same entries as the `Namespace.equals` path (including a multi-level-namespace case, or an assertion that iceberg-on-Doris namespaces are provably always single-level). Keep the db-extraction in the connector's key builder, not in the generic class. Treat PR-3 (§ residual #2) as deferrable if this parity can't be cheaply proven. + +--- + +## 3. [major] The generalized gate silently protects only caches placed on `*Connector.java`; nothing enforces that a `SUPPORTS_USER_SESSION` connector puts its cross-query caches there + +**Issue.** §C.2 keeps "scan the OWNER file only (`*Connector.java`)" and treats constructor-injected `*Cache` fields on `*ConnectorMetadata`/`*ScanPlanProvider` as "unmarked by design." Generalizing Stage-1/2 to "any declarer" makes this file-scoping a load-bearing, N-connector invariant with zero enforcement. + +**Reasoning.** Today it is safe only by luck: iceberg happens to hold all five caches on `IcebergConnector` (`IcebergConnector.java:169-200`). A future (or even this round's hudi) session=user adopter that holds its `(table,instant)` cache on `HudiConnectorMetadata` or a scan provider would declare the capability, pass the gate (the declaring `*Connector.java` has no unmarked `*Cache` field), and leak. The gate's whole purpose — "added a new cross-query cache and forgot to isolate it becomes a build failure" — is defeated for any cache not physically on the Connector class. + +**Fix.** When a connector is in the declarer set, scan its whole module for `*Cache` **holder** fields (final `…Cache` type), not just `*Connector.java`; OR add a companion invariant check that a declaring connector may hold authz-sensitive `*Cache` fields only on the Connector class and fail otherwise. The §C.2 "false-positive on injected reference fields" concern is real, but the fix is to distinguish holder (`new …Cache(`) from injected reference (ctor param) — not to narrow the scan to one file. + +--- + +## 4. [major] The statement-scope seam's correctness rests entirely on `queryId` lifecycle, which the design extends to three new connectors without verifying it + +**Issue.** `resolveInStatement` (and iceberg's existing `IcebergStatementScope.sharedTable`, `IcebergStatementScope.java:64`) key by `session.getQueryId()`. The whole cross-statement-isolation and prepared-EXECUTE-reuse safety claim (§B.2, §B "Rule D safety," `ConnectorStatementScopeImpl.java:64-98` idempotent `closeAll`) depends on: (a) `queryId` is stable within one statement across the request thread and all off-thread scan pumps, and (b) `queryId` differs per prepared `EXECUTE` re-execution. + +**Reasoning.** Iceberg already depends on this, so it is pre-existing for iceberg — but the design generalizes the dependency to hudi/mc/es and to a shared helper, and asserts "reset per prepared EXECUTE" (§B.3, "reused prepared context sees each execution's own table") as fact without grounding it. If `queryId` is NOT refreshed per EXECUTE while the `StatementContext`/scope IS reset, the seam is safe (scope cleared); if the scope is reused but `queryId` is refreshed, also safe; but if BOTH are reused (scope + queryId), you get cross-execution stale memo — a correctness bug. This is unverified and it is the foundation everything else builds on. Residual #8 asks about mc identity but nobody verified the queryId/scope reset interaction. + +**Fix.** Before PR-2, verify against `ExecuteCommand`/`StatementContext` that either the scope is reset OR `queryId` changes on every prepared re-execution (ideally both), and encode it as a test: two EXECUTEs of one prepared statement must NOT share a memoized table. Don't ship the shared helper on an assumed lifecycle. + +--- + +## 5. [major] Hudi is the first `AutoCloseable` connector value in the scope; `closeAll` use-after-close is a hard requirement, not a "caveat" + +**Issue.** §B.3/§D.1 route `HoodieTableMetaClient` (and derived `TableSchemaResolver`/`InternalSchema`) through the scope. `ConnectorStatementScopeImpl.closeAll` (`:84-96`) closes every stored `AutoCloseable` at statement end. Until now the only closeable scope value was `ConnectorMetadata`; the shared iceberg `Table` is not closeable, so this path was never exercised for a connector data object. + +**Reasoning.** If any hudi version's `HoodieTableMetaClient` is `AutoCloseable` or holds a `HoodieStorage`/`FileSystem`, and any consumer (BE-thrift schema assembly, an off-thread scan pump, a derived schema object that lazily touches the FS) retains it past the point `closeAll` fires, you get use-after-close on the flagship connector. The impl comment claims `closeAll` "runs after the scan off-thread pumps have quiesced," but that ordering was validated for iceberg's non-closeable `Table`, not for a closeable metaClient whose derived objects may outlive the store slot. The design lists this as risk #3 with mitigation "memoize a non-closeable projection" — but leaves it optional. + +**Fix.** Make it mandatory for the flagship: memoize a **non-closeable projection** (the resolved schema/timeline snapshot the callers actually need), never the raw closeable client, unless close-at-statement-end is provably safe for that hudi version AND no derived object escapes. Add a test that exercises a scan pump reading the memoized hudi state after nominal statement end. + +--- + +## 6. [major] Hudi's secondary `(table, instant)` cross-query cache (A) conflicts with the freshness claim — it delivers either ~zero cross-query benefit or staleness + +**Issue.** §D.1 says `buildMetaClient` "reloads the active timeline for freshness" (so the per-statement metaClient memo is correct), then also proposes a cross-query `(table, instant)` partition cache keyed by `instant-as-snapshotId`. + +**Reasoning.** These pull opposite directions. If the latest instant is resolved fresh each statement (the stated freshness goal), then each statement's `(table,instant)` key is a fresh instant with near-zero cross-query hit rate — the cache buys almost nothing. If instead the latest-instant resolution is itself cached cross-query (à la iceberg `latestSnapshotCache`) to get hits, you reintroduce the TTL staleness window the freshness claim was avoiding, and rule E's "new instant ⇒ new key" is vacuous because you're pinning a stale instant. The design asserts both benefits without resolving the tension. + +**Fix.** Decide explicitly: either (a) hudi latest-instant is cross-query cached under bounded TTL+REFRESH (accept iceberg-equivalent staleness, real hit rate) — then document the staleness parity; or (b) latest-instant is per-statement fresh — then drop the (A) cross-query cache for hudi this round (per-statement memo already captures the win) rather than shipping a cache that can't hit. Don't claim both. + +--- + +## 7. [minor] Cross-connector `keyNamespace` collision is a runtime `ClassCastException`, mitigated only by hand-assigned strings with no registry + +**Issue.** §B.2 makes `keyNamespace` a required param and §Risks notes the collision, but the namespaces are free-form strings (`"iceberg.table"`, `"hudi.metaclient"`, `"maxcompute.handle"`, `"es.metadata_state"`) stored as opaque `Object` in one `ConcurrentHashMap` (`ConnectorStatementScopeImpl.java:44`). A duplicate namespace across two connectors in a heterogeneous gateway statement is caught only at runtime as a `ClassCastException`. + +**Reasoning.** The metadata-funnel already treats its key convention (`"metadata:" + catalogId` plus owner label, `ConnectorStatementScope.java:51`) as a reviewed invariant. The new seam adds a parallel, larger key space with no central definition — easy to collide under refactor, invisible until a gateway query hits it. + +**Fix.** Put the namespaces in one place (a small constants holder / enum next to `ConnectorStatementScopes` in fe-connector-api) and document uniqueness as a reviewed invariant, mirroring the funnel-key convention. Optionally fold `catalogId` before `keyNamespace` so two connectors under different catalog ids can't collide even with an equal namespace. + +--- + +## 8. [minor] `ConnectorMetadataCache` telemetry/cache names change unless the retrofit is pinned to the old names + +**Issue.** Each iceberg cache today has a distinct entry name (`"iceberg-table"`, `"iceberg-partition"`, `"iceberg-latest-snapshot"`, … at `IcebergTableCache.java:70`, `IcebergPartitionCache.java:97`, etc.), surfaced through `MetaCacheEntry.stats()`. The framework-native ctor derives `name = engine + "." + entryName` (§A.2) → `"iceberg.table"`, a different string. + +**Reasoning.** Any operator dashboard, log grep, or `*ForTest`/`loadCountForTest` assertion keyed on the old names breaks silently. The design says iceberg uses the pre-resolved `CacheSpec` ctor (which takes `name`), so it *can* keep old names — but that must be stated as a retrofit requirement, not left to the framework-native derivation. + +**Fix.** Pin the retrofit to pass the exact legacy `name` strings; add it to the PR-3 checklist and assert names in the existing cache tests so a drift fails. + +--- + +## 9. [nit] "Iron rule A is not actually crossed" is true only if the owner accepts re-reading the mandate; the fe-core B2 form still exists in the doc as a live recommendation + +Residual #1 correctly surfaces that the reachable home is fe-connector-api (iceberg/hudi can't depend on fe-core, confirmed: they import `org.apache.doris.connector.api.*`). But the doc simultaneously recommends B2 (fe-core growth) for maxcompute. Pick one posture: if the design's thesis is "rule A stays intact," then B2 should be removed, not recommended — see objection #1. Leaving both makes the "rule A untouched" headline conditional on a decision the doc elsewhere pre-empts. + +--- + +## Overall verdict + +**Request changes.** The foundation genuinely mostly exists and the direction is sound, but the design overstates parity in three shipped-code-touching places: the fe-core B2 memo (blocker for that variant — unbounded cross-connector blast radius, use B1), the iceberg db-invalidation semantics change (major — not byte-identical, `Namespace` vs `String` equality), and the gate's unenforced "caches live on `*Connector`" invariant (major — defeats the gate's purpose for any cache held off the Connector class). Two more majors are unverified-foundation risks (queryId/prepared-EXECUTE lifecycle; hudi `AutoCloseable` use-after-close) and one is an internal contradiction (hudi freshness vs the (A) cross-query cache). None are unfixable; all are cheap to close before the respective PRs, and PR-1 (generic wrapper) plus a lifecycle-verified PR-2 can proceed once objections #4 and the #2 parity test are settled. \ No newline at end of file diff --git a/plan-doc/connector-cache-unification/designs/review-2.md b/plan-doc/connector-cache-unification/designs/review-2.md new file mode 100644 index 00000000000000..2d29205395ca30 --- /dev/null +++ b/plan-doc/connector-cache-unification/designs/review-2.md @@ -0,0 +1,44 @@ +Verification complete against HEAD.

Hudi can mirror it as a connector-private `HudiStatementScope.sharedMetaClient` — zero shared surface, each connector owns its own key convention, which the design itself concedes must be connector-distinct (the `keyNamespace` param is *required* precisely because the convention can't be shared).

Writing the adversarial review. + +--- + +# Adversarial design review — cache-unification (AUTHZ + FRESHNESS lens) + +Verification anchored at HEAD. The recon's structural claims hold: `ConnectorPartitionViewCache` is the octet the design describes (fe-connector-cache/…/ConnectorPartitionViewCache.java:46-110), it is live in iceberg/hive/paimon, the "NO consumers yet" javadoc is stale (same file:33-34), the gate hardcodes `TARGET_REL` to IcebergConnector.java (tools/check-authz-cache-sharding.sh:52-54), and hudi/mc/es declare no `SUPPORTS_USER_SESSION`. But three cache-safety objections survive, and the most severe one attacks the exact question in my mandate. + +## [BLOCKER] D3's generalized gate cannot see the generic wrapper's real instantiation sites — a future per-user connector that builds its `ConnectorMetadataCache` outside `*Connector.java` gets zero coverage + +**Issue.** The gate scans **field declarations on the owner `*Connector.java` file only** (script:52-54, `FIELD_DECL` at :80, and §C.2 enshrines "Scan the OWNER file only … never the whole module" as an invariant). But the generic wrapper is already declared in **two** places per connector — the Connector (marked) *and* the `*ConnectorMetadata` (unmarked, injected): +- iceberg: IcebergConnector.java:197-200 (marked) vs IcebergConnectorMetadata.java:170-171 (unmarked) +- hive: HiveConnector.java:112 vs HiveConnectorMetadata.java:241 +- paimon: PaimonConnector.java:143 vs PaimonConnectorMetadata.java:108 +- maxcompute: MaxComputeDorisConnector.java:61 vs MaxComputeConnectorMetadata.java:79 + +Today this is safe only because every connector *also* constructs and holds the instance on the Connector, where the marker sits. The gate's guarantee is therefore "every `*Cache` field textually present in `*Connector.java` of a declaring connector is marked" — **not** "every cross-query cache instance reachable by a declaring connector is isolated." + +**Reasoning.** Generalization actively worsens this. Today's `Iceberg*Cache` are dedicated classes the author naturally constructs in the Connector. A generic, injectable `ConnectorMetadataCache` is trivially constructed *anywhere* — a metadata object, a `*ScanPlanProvider`, a factory. A future connector that declares `SUPPORTS_USER_SESSION` and does `new ConnectorMetadataCache<>(...)` inside its `*ConnectorMetadata` (never touching `*Connector.java`, exactly as the injected field already lives there today) produces a name-keyed cross-query cache the gate structurally cannot see. That is precisely the "future per-user connector silently gets a name-keyed cross-query cache the gate fails to catch" failure I was told to hunt. The design bakes the hole in by declaring owner-file-only an invariant. + +**Fix.** Gate on the **construction expression**, location-independently: within any connector module whose `*Connector.java` declares `SUPPORTS_USER_SESSION`, grep module-wide for `new ConnectorMetadataCache<` / `new ConnectorPartitionViewCache<` (and the residual `new *Cache(` holders) and require each such construction site to carry a marker or sit under a capability null-gate. Keep the owner-file field-decl scan as a secondary net. A construction-site gate is inherently immune to where the field is *declared*. + +## [MAJOR] The marker is an unverified, copy-pasteable comment; the opaque wrapper moves the only real safety (the null-gate) into a construction idiom the gate never checks + +**Issue.** Safety is entirely convention: the connector writes `isUserSessionEnabled() ? null : new ConnectorPartitionViewCache<>(...)` (IcebergConnector.java:279-284) and the wrapper is value-opaque (ConnectorPartitionViewCache.java:46, "holding an opaque value V"). The gate only checks that the *marker string* is present near the field decl — it never checks that construction is actually null-gated. + +**Reasoning.** With a generic wrapper, PR-1/PR-4/PR-5 will copy both the field+marker line *and* the ternary idiom into new connectors. A mis-paste that keeps the marker but drops the `isUserSessionEnabled() ? null :` guard (or guards on the wrong flag) is a silent cross-user leak that passes the build GREEN — the marker asserts a discipline the code no longer honors. This is a pre-existing weakness, but generalization multiplies the copy-paste surface and detaches the marker (on the field) from the guard (at construction), making drift easier. + +**Fix.** Tie the gate to the construction guard, not just the field marker: for a `authz-cache-session-user-disabled` field, assert its assignment RHS is a capability-gated ternary (or the field is provably null under the capability). Add a RED self-test fixture: field marked disabled, constructed unconditionally → must FAIL. Without this, D3 verifies a comment, not a behavior. + +## [MAJOR] Stage-2's `.contains(` exclusion drops HiveConnector, which already holds an unmarked, unconditional, name-keyed cross-query cache AND is the gateway delegating to per-user iceberg/hudi + +**Issue.** §C.2 excludes lines with `.contains(`, so HiveConnector (whose only `SUPPORTS_USER_SESSION` reference is `sibling.getCapabilities().contains(...)` at HiveConnector.java:543) is classified a non-declarer and never scanned. Yet HiveConnector.java:112/134 holds `partitionViewCache`, an **unmarked, unconditionally-constructed, (db,table,-1,-1)-keyed cross-query cache** (comment at :108-111 says hive has "NO session=user … cache-disabling convention … constructed unconditionally"). And hive is the HMS gateway that delegates to per-user iceberg/hudi siblings. + +**Reasoning.** Today this is safe by a *runtime* guarantee, not the gate: the front door "never declares SUPPORTS_USER_SESSION" (comment :537) and fail-louds if a sibling does (:543-546). The design's residual #7 frames hive as merely "in-gate-scope or documented out." That undersells it: hive has a *live* cross-query cache that the generalized gate is *structurally blind to* by construction (the `.contains(` exclusion), so the entire safety of the gateway path rests on one runtime assertion the gate does not verify. If a future refactor makes the hive front door per-user (or the fail-loud assert is weakened), the gate stays GREEN while hive's `partitionViewCache` leaks. + +**Fix.** Treat a connector that *reads* a sibling's `SUPPORTS_USER_SESSION` (the gateway signature) as in-scope, and gate the presence of the fail-loud front-door assertion. At minimum, require hive's `partitionViewCache` to carry an explicit `authz-cache-exempt` marker with the "front door never per-user + fail-loud guard" justification, so the exemption is a reviewed claim rather than an invisible gap. + +## [MINOR] Hudi `(table, instant)` key: correctness needs "latest **completed** instant, re-read fresh per statement" — the design asserts correctness without pinning either + +**Issue.** §D.1 keys the cross-query partition cache by `(db, table, instant-as-snapshotId, -1)` and claims "always-correct (new instant ⇒ new key)." But correctness depends on two unstated properties: (a) the instant is the latest **completed** instant (not a requested/inflight one), and (b) it is re-derived **fresh each statement** from the per-statement metaClient that reloads the active timeline. + +**Reasoning.** If the key uses an inflight/requested instant, a concurrent writer can bind the entry to a partial partition set. If the instant is sourced from anything longer-lived than the per-statement metaClient, a stale instant can serve a stale partition list while still labeled "latest." The instant-in-key argument is only as strong as the freshness of the instant that forms it. + +**Fix.** Specify: the key uses `metaClient.getActiveTimeline().filterCompletedInstants().lastInstant()` (or equivalent), re-derived from the statement-scoped metaClient each statement. Add an e2e that lists partitions across a concurrent hudi commit and asserts no partial/stale set (this also satisfies the memory rule that HMS-delegated capabilities need e2e). + +## [MINOR] Enforce, don't just intend, the hudi/es freshness boundaries + +**Issue/Reasoning.** Two intent-level safeties need a test to be real: (1) es — the memoized `EsMetadataState` must hold only mapping/field-context and `fetchShards()` must re-run every statement (es has **no** `*Cache` field at HEAD — grep empty — so there is nothing to regress *yet*, but PR-6 introduces the memo); (2) hudi — the raw metaClient must stay in the per-statement seam and must never be promoted into the cross-query `ConnectorMetadataCache` layer, and the `closeAll` AutoCloseable caveat (§B.3 / Risks) must be checked so a statement-end close cannot corrupt the derived `(table,instant)` list (which stores `List`, not the client — so OK, but assert it). + +**Fix.** Add assertions/tests: es shard routing re-runs per statement; the hudi cross-query cache value type is a pure projection with no live metaClient/FileSystem reference. No design change, but make these gate-tested rather than convention. + +## [NIT] Rename churn + stale javadoc + +`PartitionViewCacheKey → ConnectorTableKey` re-touches iceberg/hive/paimon main+test imports (mechanical, low risk). Fix the confirmed-stale "this class has NO consumers yet" javadoc (ConnectorPartitionViewCache.java:33-34) in PR-1 as the design already notes. + +--- + +**Overall verdict: DO NOT SHIP D3 AS DESIGNED.** The A/B/D/E cache *placements* survive the authz+freshness lens (all D1 connectors use static creds; hudi's instant-in-key is sound once "completed + fresh" is pinned; es shard routing stays per-statement). But the gate generalization (D3) is the weak seam: as specified, it verifies owner-file field markers, while the generic wrapper's real instantiation sites already live unmarked in `*ConnectorMetadata` today and can move anywhere tomorrow — so a future per-user connector can obtain a name-keyed cross-query cache the gate cannot see (BLOCKER), the marker is an unverified comment detached from the actual null-gate (MAJOR), and hive's live unmarked cross-query cache plus its per-user delegation path fall structurally outside the gate (MAJOR). Re-scope D3 to gate cache **construction expressions** module-wide within capability-declaring (and gateway) connectors, and assert the null-gate, before the wrapper is generalized — otherwise the generalization ships a wider attack surface with a narrower gate. \ No newline at end of file diff --git a/plan-doc/connector-cache-unification/progress.md

**未被测试压住的 6 行**：`loadBuiltins` / `loadPlugins` 这两段循环体**两边都没有测试** + （`ConnectorPluginManagerTest` 的 16 个用例全是直接调 `registerDiscovered`，不走这两个入口； + 要压住得往 fe-core 测试 classpath 塞 `META-INF/services` 或造插件目录，代价远超收益）。 + **本轮靠对照兄弟类 `FileSystemPluginManager` 逐行读来确认**，不是靠测试。改这两段时要知道这点。 +2. ~~**`discard` 不对称**~~ **已补齐（用户拍板）**：合并后 `loadPlugins` 的两条拒绝路径现在都调 + `runtimeManager.discard(handle.getPluginName())` 关掉插件 classloader，对齐 `FileSystemPluginManager` + 「每条拒绝路径都 discard」的惯例。**安全性依据**：`registerDiscovered` 返回 `false` 时 + `claimedTypes.add` 被 `problem ==

`LOG.error` 过拒绝理由，再记一条就是重复。 + +--- + +## 上上上轮（2026-07-27）：rebase 到上游 `1aa5ae9597e` —— 「零冲突」但树是坏的 + +`git pull --rebase upstream-apache branch-catalog-spi`，**72 个提交全部重放，0 个文本冲突**， +`range-diff` 71 个

因为第十三批 + （`executeStmt` / `getColumnsFromQuery` 搬去 `ConnectorPassthroughSqlOps`）和 + `drop the create-database mirror switch`（删 `supportsCreateDatabase()`）**没同步基线资源**而失败。 + `ConnectorMetadata.java` 与

+代码侧这条工作线已经做完。剩下的全部是**积压的端到端与插件包重部署冒烟**（见下方欠账清单），本地无集群一律跑不了。 + +如果要继续在代码上找事做，下面这些是本轮顺带记下的、**没有人认领**的候选（都不是这条线的欠账）： + +- `streamSplits` 与 `getScanNodeProperties` / `getScanNodePropertiesResult` 仍是位置参数（5 参 / 4 参）。它们**没有重载链**，所以没有 `planScan` 那种「实现了却静默失效」的陷阱，本轮刻意没动。真要统一风格可以让它们也接 `ConnectorScanRequest`。 +- 引擎构造扫描请求时若漏掉 `.countPushdown(...)`，COUNT(*) 下推会静默退化成全量扫描，而 fe-core 侧**没有任何单测**压这个调用点（连接器侧有 paimon/iceberg 的 countPushdown 用例，但它们直接调 `planScan`）。这不是本轮引入的，改造前那个位置参数同样没被压住。 +- 逐个连接器接入 `renderShowCreateTableDdl`（今天只有 hive 在用），各自独立排期。 + +--- + +## 📌 第十四批落地后的事实变化（1 个提交） + +1. **`ConnectorScanPlanProvider.planScan` 只有一个方法了**：`planScan(ConnectorSession, ConnectorScanRequest)`。四个重载（4/5/6/7 参）全部删除。 +2. **新增下推信号不再新增重载**：往 `ConnectorScanRequest` 加一个带默认值的字段即可，所有连接器自动拿到，**不可能再出现「实现了最短的那个抽象方法、静默失去 limit / 分区裁剪 / COUNT 下推」**。 +3. **`planScanForPartitionBatch(session, request, partitionBatch)`**，默认实现走 `request.withRequiredPartitions(batch)`。hive 仍然覆写它（它的 `planScan` 不是按分区集作用域的，继承默认会每批重放整个裁剪集 → 重复行）。 +4. **请求对象的默认值就是「引擎没有额外要求」**：无过滤、limit = -1、分区集为空（= 扫全部）、无 COUNT 下推。`requiredPartitions` 传 `null` 与传空等价（引擎在裁剪到零时早就短路了，走不到这里）。 +5. **零行为变化**：每个连接器收到的值与改造前逐字相同；批模式那条路仍然是「无 limit、无 COUNT 下推」。 + +--- + +## 📌 第十三批落地后的事实变化（8 个提交） + +1. **`estimateScanRangeCount` 已删除**（SPI 默认 + jdbc 覆写），全仓复扫零命中。 +2. **`ConnectorTableOps` 现在真的什么都不声明了**，只是六个域接口的聚合。SQL 直通搬进新的 **`ConnectorPassthroughSqlOps`**（可选接口，jdbc 实现）。 +3. **`ConnectorCapability.SUPPORTS_PASSTHROUGH_QUERY` 已删除**。判据改为「metadata 是否 `instanceof ConnectorPassthroughSqlOps`」——**实现接口就是声明本身**，不再有能力位与实现两个答案。两个入口（`query()` TVF、`CALL EXECUTE_STMT`）都改成类型判定。 +4. **`ConnectorSchemaOps.supportsCreateDatabase()` 已删除**，`CREATE DATABASE IF NOT EXISTS` 的远端存在性预检改为**无条件**（对齐 Trino 的 `CreateSchemaTask`）。 + **⚠ 唯一的用户可见行为变化**：jdbc / es / trino / hudi 目录上 `CREATE DATABASE IF NOT EXISTS <远端已存在的库>` 由「报 CREATE DATABASE not supported」变成**静默成功**。两个问题都不回答的连接器（`databaseExists` 保持默认 false）行为不变。 +5. **`ConnectorWriteHandle.getWriteContext()` → `getStaticPartitionSpec()`**，与引擎侧产出方同名。 +6. **`JdbcQueryTableValueFunction` → `PluginDrivenQueryTableValueFunction`**（fe-core 里最后一个按数据源命名、实际服务任意连接器的类）。 +7. **`supportsCastPredicatePushdown` 现在没有任何连接器是「继承来的」**：iceberg / es / trino 就地声明 `true` 并写明各自拿这个谓词做什么、`true` 是接受风险而非安全声明；hive / hudi **对残余谓词零消费**（`planScan` 与 `getScanNodeProperties` 都不看），这个开关对它们是死的，因此不加空覆写，改在 SPI 文档里记下整张地图。零行为变化。 +8. **契约校验器的每条不变量都有真连接器正样本了**：maxcompute 压 local-sort 臂，新增的 `HiveConnectorContractTest` 压 hash 臂与两臂互斥。 + +--- + +## 📌 第十二批落地后的事实变化 + +1. **`ConnectorContext` 只剩 7 个方法 + 一个 `getStorageContext()`**（404 行 → 155 行）。新增存储服务加在 `ConnectorStorageContext`，**不要加回 `ConnectorContext`**。 +2. **钉桩失效的残留风险写在两处注释里**：今天没有任何存储方法跑插件代码；将来若有，钉桩子类必须覆写 `getStorageContext()` 返回自己的包装。 +3. **测试替身的静默退化是隐性风险**：替身实现了 `ConnectorStorageContext` 却忘写 `getStorageContext()` 时能编译过，覆写全变死代码。 +4. **`ForwardingConnectorContextTest` 是反射驱动的**，`ConnectorContext` 上加方法不加转发会直接构建失败并点名方法。 +5. **插件包必须与 FE 同版本部署**。混部表现为运行期 `AbstractMethodError`，不是启动期拒绝。 + +--- + +## 📌 第十一批 / 第十批落地后的事实变化（仍然成立） + +1. **外部表的引擎名由连接器说了算**（`ConnectorProvider.displayEngineName()`，默认取目录类型名，只有 MaxCompute 覆写）。`SHOW CREATE TABLE` 的 `ENGINE=` 与 information_schema 的 ENGINE 列取同一个值。 +2. **`displayEngineName()` 与 `acceptedCreateTableEngineNames()` 是两件事**：hms 目录**显示** `hms`、**接受** `ENGINE=hive`。 +3. **`CreateTableInfo` 里没有任何引擎名判定**，改按目标目录路由；外部目录的建表语句不带引擎名（null），这是刻意的。 +4. **`MODIFY ENGINE` 子系统已删除**，但**刻意保留** `ModifyTableEngineOperationLog` / `OperationType.OP_MODIFY_TABLE_ENGINE` / 重放分支——老镜像要能读。 +5. **引擎名从来没有被持久化过**，所以这条线不需要镜像版本号 / gson 迁移 / editlog 垫片。 + +--- + +## ⚠️ 做下一批之前必看 + +1. **`UnusedLocalVariable` 是开启的**（第十四批踩到）：把方法参数改成「从请求对象解包成同名局部变量」时，只解包**真正用到**的那些——多解一个就是 checkstyle 失败。判断「用到了吗」别用裸 grep（hudi 的 `columns` 只出现在**别的方法**里，多解了一个）。 +2. **任务文档与登记表会过期，动手前必须按符号重侦察。** 第十三批又实证一次：登记表把「hive 契约正样本」「读事务矛盾」估成中等成本，实际都是低；而 `supportsCastPredicatePushdown` 登记的「五个连接器继承默认值」是错的——其中两个（hive/hudi）根本不消费残余谓词，那个开关对它们是死的。**别按登记表的成本估算排期，先看代码。** +2. **`git commit` 提交的是整个索引，不是你刚 `git add` 的那几个文件。** 第十三批踩到：更早的 `git mv` 把重命名留在索引里，被第一个提交顺手带走，留下一个**编译不过**的中间提交（文件名已改、类名未改）。修法是 `git reset --mixed HEAD~N` 后逐个重做。**每次提交前先 `git status --porcelain` 看索引里到底有什么。** +3. **改名类改动会撞行长上限**：`getWriteContext` → `getStaticPartitionSpec` 让 iceberg 一行超 120 字符被 checkstyle 挡。改名后一定要跑改动模块的 `checkstyle:check`。 +4. **`CustomImportOrder` 对新增 import 很敏感**：`sed` 插 import 时按字典序插，`ConnectorMetadata` 在 `ConnectorPassthroughSqlOps` 之前。 +5. **hive 连接器的单测不能碰 `getOrCreateClient()`**（会建真的 `ThriftHmsClient`，测试环境没有 Hadoop 栈）。要真实的写提供者就直接 `new HiveWritePlanProvider(null, props, ctx)`（构造是纯赋值），或匿名子类覆写 `getWritePlanProvider()`。 +6. **纯 Mockito mock 上的新方法默认返回 null / 什么都不做**。加 SPI 方法后必须查所有 mock 该接口的测试。 +7. **仓库有 60 余个顶层未跟踪项**（含明文密钥的配置、临时日志、workflow 脚本）。**严禁 `git add -A`**，一律显式路径。 +8. **删除类改动必须配全仓符号 grep + 清空 `test-classes` 后重跑**。 + +--- + +## 🧭 待用户拍板 + +完整清单在 **[open-decisions.md](./open-decisions.md)**。**已拍板三十四条**（第十三批新增四条：建库布尔位删除 / SQL 直通独立接口并删能力位 / `planScan` 收成请求对象 / CAST

条（唯一一条会改变用户可见行为的）**： + +**`CREATE DATABASE IF NOT EXISTS` 在不能建库的目录上**：拿一个 jdbc（或 es / trino / hudi）目录，对一个**远端已存在**的库执行 `CREATE DATABASE IF NOT EXISTS `，断言**成功且无输出**（改动前会报 `CREATE DATABASE not supported`）；再对一个**不存在**的库执行同一条语句，断言仍然报 `CREATE DATABASE not supported`。两条都需要真集群。另需回归 jdbc 的 `query()` TVF 与 `CALL EXECUTE_STMT`（入口判定换成了类型判定）。 + +**第十二批新欠 1 类（最重的一条，仍未跑）**： + +**插件包重部署冒烟**——`mvn

`ENGINE=maxcompute` 需真实阿里云账号）；trino-connector / max_compute 的 ENGINE 列不再是 NULL 但全仓零断言，值得补一条。 + +**第十批欠的**：7 处改写后的断言必须实跑（`test_iceberg_create_table.groovy:61,66,71` 与

新增数据源相关代码；遇到「删 A 才能编译过」就把逻辑就近挪进 `fe-core` 工具类的冲动时，停手重新分析真实归属。 + +--- + +## 五、需要拍板的事 + +完整清单见 **[open-decisions.md](./open-decisions.md)**（约 40 条，多数有推荐值照做即可）。**必须先定的四件事**（其中两件已拍板）： + +1. ~~**含隐式类型转换的谓词下推默认值**（08 号）~~ **已拍板并落地**（2026-07-26，第十三批）：保持默认 `true`，但让每个连接器显式写出自己的答案。侦察发现它并非五家齐一——iceberg / es / trino 真的会拿它做源端过滤（三家就地声明 `true` 并写明这是「接受风险」而非「安全声明」），hive / hudi 对残余谓词根本不消费、这个开关对它们是死的（因此不加空覆写，改在 SPI 文档里记下整张地图）。零行为变化。 +2. ~~**连接器自声明属性：接线还是删除**（24 号）~~ **已拍板：删除**（2026-07-25），已随 11 号落地，入口形状写进了包级说明的规则七。 +3. **建表能力下沉的报错文案变化**（18 号）：三类组合的拒绝点会提前、文案会变。同一份文档还纠正了一个会误导施工的事实——**仓库里根本不存在分桶子句的正向端到端护栏**，这个高风险任务必须自己补一条。 +4. ~~**插件与内建目录类型的路由优先级**（15 号）~~ **已拍板并落地**：插件优先（现有类型行为不变）+ **三个内建类型名成为保留字，插件声明它们时在注册期就被拒绝**。借鉴 Trino 的「单一注册表 + 重名直接拒绝」，于是「遮蔽」不再是需要接受的代价。 + +11 号里的「是否外部表」字段**已拍板：删除**（2026-07-25）。判断依据见那份任务文档的落地记录第 8 条：它在任何能到达连接器的路径上都是编译期常量 `true`，而「保留并让 hive 真正消费」按字面做会把所有 Doris 建的 hive 表从托管表改成外部表、`DROP TABLE` 不再删数据。读侧的主键方法**已拍板：删除**（2026-07-25，随 12 号落地）——两条通道都没有读取方，其中保留属性键那条是「写进去就被剥掉」。 diff --git a/plan-doc/connector-public-interface-cleanup/audit-report.md

表与库元数据 / 写入与事务 / 扫描与分片 / 下推 / 多版本与统计 / 存储过程与建表请求 / 会话与装配层 / 校验与事件），5 个按横切维度（可扩展性卡点穷举、源专有语义扫描、死接口面普查、契约一致性核对、重复机制排查）。每个单元都被明确要求**只看代码**，不得阅读 `plan-doc/` 下任何已有评审文档，且每条结论必须给出在当前代码上实测到的 `文件:行号` 与原文摘录。 +2. **对抗式复核**：把去重后的每一条结论交给复核者，复核者的默认立场是「这条是错的」，只有在代码上亲自验证且推翻失败时才判为成立。复核者要重跑「无调用方 / 无实现方」类断言的全仓搜索，并检查建议是否撞上客观障碍（例如 `fe-core` 只出不进的隔离纪律、Gson 持久化兼容、跨插件类加载器边界、FE 与 BE 的 thrift 有线格式兼容）。 +3. **我本人的独立通读**：在上述结论产出之前，我自己完整读过 `Connector`、`ConnectorMetadata`、`ConnectorType`、`ConnectorCapability`、`ConnectorSession`、`ConnectorProvider`、`ConnectorContext` 全文，以及六个 `Ops` 子接口和两个 Provider 的全部方法签名，并亲手验证了若干条最容易误判的结论（死接口面、契约校验器是否真的在跑）。文档里的判断以这一层为准，不是转述。 +4. **交叉核对与完备性补检**：一个单元持有两轮结论并逐条回到代码实测，产出附录 C；另一个单元反过来问「这轮漏了什么」——把 100 个公共源文件与已确认结论做交叉、逐个读完 19 个完全未被覆盖的文件、并把「由引擎实现、连接器消费」的那几个接口当作一类单独审，产出附录 D。**附录 D 里有本次调研最有行动价值的一条**（引擎实现的接口默认值全是静默降级，且两个类加载器钉桩包装类今天已经漏转发），以及第二、第三个可能静默少行的连接器缺陷。 + +### 1.2 结论规模与可信度口径 + +原始结论 194 条，跨单元去重后 176 条，经对抗复核： + +| 判定 | 条数 | 含义 | +|---|---|---| +| 成立 | 59 | 现象与原因都经代码验证，确实违反公共接口设计原则 | +| 部分成立 | 113 | 现象存在，但原始描述过宽、定位不准或原因分析有误；复核给出了更准确的表述 | +| 被推翻 | 4 | 事实错误，或有充分设计理由、不应算缺陷 | + +附录 D 的补检结论**不在这 172 条里**（它们是针对本轮盲区新增的），其中包含 1 条高、1 条中高与若干条低。 + +「部分成立」占比高（三分之二）本身是一个重要信息：**这套接口的问题大多不是「某个方法写错了」，而是「文档说的和代码做的不是一回事」**——所以第一遍看代码的人容易把现象描述得比事实更严重。文档正文采用复核后的准确表述；附录 A 给出全部 172 条成立/部分成立结论的完整清单，逐条带位置，可独立复核。 + +**行号可能随后续提交漂移。核对时请以符号名为准，不要以行号为准。** + +### 1.3 与同一天另一份文档的关系 + +`plan-doc/connector-api-spi-design-review-2026-07-25.md` 是同一天早些时候另一轮审查的产物（689 行）。本文是**独立重做**的一轮，写作时正文结论完全不依赖那份文档；两者的交叉核对结论见附录 C。保留两份而不是覆盖，是因为两轮独立结论的一致部分本身就是最强的可信度证据，而分歧部分正是最需要人来拍板的地方。 + +### 1.4 一句话结论 + +**这套接口的抽象层次和默认值设计是对的（全默认方法 + 能力 opt-in，与 Trino 的路线一致），真正的问题集中在五件事上：** + +1. **引擎侧还留着一层按数据源类型名硬编码的开关**，使得「注册了插件就能工作」这个承诺目前不成立——最关键的一处是 `fe-core` 里的类型白名单。 +2. **「声明一项能力」有多条并行通道**，其中一条是把能力名拼成逗号分隔字符串塞进属性表，拼错不会报错、只会静默失效。 +3. **接口文档与实现大面积脱节**：有的方法文档承诺的用途和真实用途完全不同，有的契约（异常、单位、null 语义）被实现有意违背，有的扩展点从来没有被引擎调用过。新连接器作者按文档写，会写错。 +4. **有相当规模的死接口面**：零调用方或零实现方的方法/类/枚举。它们的成本不是占空间，而是**逼着每个新连接器为不存在的出口交税**，并持续制造「我实现了为什么没生效」的排查浪费。 +5. **由引擎实现的那几个接口（上下文、会话）几乎全是带默认实现的方法，而默认值都是「静默降级」**。它既让引擎可以合法地不履约，也让连接器侧的逐方法转发包装类漏一个方法都不会报错——**今天已经漏了**（附录 D.2）。这一类接口此前没有被任何审查视角覆盖过。 + +--- + +## 二、判断标准 + +调研用的是下面八条公共接口（API/SPI）设计原则。它们不是凭空拟的，前四条对应用户提出的四类问题，后四条是审查过程中必须一并核对的配套要求。 + +1. **中立性**：这两个模块被所有连接器共享，不应出现只有某一个数据源才有的概念、命名、常量或语义假设。要特别警惕第二种形态——**名字是通用的，但语义只对某一个源成立**，这比直接写 `hive` 更危险，因为它不会被任何按名字扫描的检查发现。 +2. **可扩展性**：新增一个连接器不应需要修改 `fe-core`、`fe-connector-api`、`fe-connector-spi`。封闭枚举、类型白名单、按类型的 `switch` 与 `if` 链、对公共类型的 `instanceof` 链、硬编码注册表，都违背这一点。 +3. **无冗余**：不应存在没有生产调用方或没有实现方的接口；同一件事不应有多套并存的表达；不应有无意义的重载堆叠或几乎重复的值对象。 +4. **语义清晰**：方法名要与实际行为一致；返回值的单位、`null` 与空集合的区别、异常契约、线程安全、幂等性要写清；不应用 `Map` 偷运结构化信息而不定义键的契约。 +5. **单一职责**：一个接口不应把互不相干的能力捆在一起，逼迫连接器实现与自己无关的方法。 +6. **实现一致性**：接口文档声明的契约，各连接器的实现要真的遵守。 +7. **对称性**：读与写、表级与连接器级、单条与批量等成对能力不应有缺口。 +8. **抽象不泄漏**：公共接口不应暴露引擎内部类型，也不应要求连接器依赖引擎内部实现细节。 + +**关于第 2 条有一个前提必须先说清，否则后面每一条建议都会被它误伤：**「新增连接器不应需要修改公共模块」禁止的是「**每**新增一个连接器都要**再**改一次」，不是「永远不许往公共模块加声明位」。给 `ConnectorProvider` 加一个带默认实现的方法，是一次性的开放动作——加完之后第 9 个、第 10 个连接器都不必再碰它。本文所有「新增声明位」的建议都是这个性质；凡是做不到一次性的（例如 BE 侧按数据源开的 thrift 槽位），一律归入「结构性约束，不建议动」。 + +--- + +## 三、总体判断 + +### 3.1 先说做得对的部分 + +为了让后面的批评有参照，先明确这套接口在架构上做对了什么——这些**不应该**在整治中被改回去： + +- **全默认方法 + 能力 opt-in**。`ConnectorTableOps` 的 46 个方法全部有默认实现，`ConnectorScanPlanProvider` 24 个里 23 个有默认实现。新连接器只实现自己支持的部分，其余自动降级。这与 Trino 的 `ConnectorMetadata`（上百个默认方法）是同一条路线，是正确的。 +- **异构网关的按表 provider 选择**。`Connector.getScanPlanProvider(handle)` / `getWritePlanProvider(handle)` / `getProcedureOps(handle)` 让一个目录服务多种表格式（Hive 元存储目录里的 Iceberg 表委派给 Iceberg 连接器）。Trino 没有这个模型（它靠多个目录解决），这是 Doris 特有且必要的本地化。 +- **按语句作用域的解析记忆（`ConnectorStatementScope` / `ConnectorStatementScopes`）**。键的约定（命名空间以连接器类型名为前缀，因此跨连接器不撞由构造保证）写得清楚，且刚刚完成了把源专属命名空间常量下沉到各连接器、公共模块只留中立约定的整理。这是本轮唯一一处「接口设计做得完全干净」的地方，可以作为其它部分的范本。 +- **存储与凭证的归属**。属性解析放在插件侧、`fe-core` 不解析元存储属性，这条既定架构目标在 `ConnectorContext` 上被贯彻得比较彻底。 + +### 3.2 五个结构性问题（一句话版） + +| # | 问题 | 最关键的一处证据 | +|---|---|---| +| 一 | 引擎侧的类型白名单让「装了插件就能用」不成立 | `fe-core` 的 `CatalogFactory.java:56` 用一个写死的七元素集合决定谁能走插件路径 | +| 二 | 「声明一项能力」有多条并行通道，其中一条无编译期约束 | `ConnectorTableSchema.java:98` 把能力名拼成逗号分隔字符串塞进属性表，且只对 13 个能力中的 5 个生效 | +| 三 | 入口接口与元数据接口把互不相干的职责捆在一起 | `Connector` 34 个方法里有 11 个只是把写计划提供者的同名方法再镜像一遍 | +| 四 | 相当规模的死接口面，且有的还是**强制实现**的 | `ConnectorScanRange.getRangeType()` 是 8 个连接器必须实现的抽象方法，它的返回值全仓库无人读取 | +| 五 | 接口文档与实现脱节，新人照文档写会写错 | `ConnectorTableOps.listPartitionValues` 的文档说它服务某个表函数，而那个表函数走的是另一个方法；这个方法零生产调用方，却有三个连接器实现了它并配了单测 | +| 六 | **由引擎实现的那几个接口，默认值全是「静默降级」，而且今天已经有两个包装类漏转发** | `ConnectorContext` 19 个方法里 17 个有默认实现，iceberg 与 paimon 的类加载器钉桩包装类各漏转发 1～2 个方法，漏转发不报编译错、只会静默返回接口默认值（`getFileSystem` 默认返回 `null`）。详见附录 D.2 | + +--- + +## 四、主题一：新增一个连接器，今天必须碰公共模块的哪些地方 + +这是本次调研最核心的一节。26 项相关结论按「一个仓库外的第三方连接器作者今天会撞上什么」分层，因为混在一起看会导致投入错配。 + +### 4.1 硬阻塞：不改公共模块，连接器根本跑不起来，或该能力完全不可用 + +#### （1）目录类型白名单——最该删的一处 + +`fe/fe-core/src/main/java/org/apache/doris/datasource/CatalogFactory.java:56` 有一个写死的集合： + +```java +private static final Set SPI_READY_TYPES = + ImmutableSet.of("jdbc", "es", "trino-connector", "max_compute", "paimon", "iceberg", "hms"); +``` + +判定点在同文件 `:110` 与 `:119`：**只有类型名落在这个集合里，引擎才会去问插件**。一个第三方连接器即使正确注册了 `ConnectorProvider`、被插件加载器成功装配，`CREATE CATALOG` 也不会走到它——会掉进后面的内建类型 `switch`，最终抛「未知目录类型」。 + +这个集合目前承担两件事，必须拆开看： + +- **迁移期灰度门禁**：只让这七个类型走插件路径。这个作用可以直接删。 +- **排除 hudi**：hudi 已经注册了 `ConnectorProvider`（返回类型名 `"hudi"`），但它没有独立的目录概念——一张 hudi 表寄生在 Hive 元存储目录上，运行时由 hms 网关通过 `ConnectorContext.createSiblingConnector("hudi", ...)` 构造为内嵌兄弟连接器。代码注释里明确写了「不要把 hudi 加进这个集合」。这个作用必须有替代品。 + +**建议**：把第二件事上移为 provider 的显式声明，然后删掉白名单。 + +```java +// fe-connector-spi: ConnectorProvider +/** + * 本 provider 的类型能否作为一个独立目录出现在 CREATE CATALOG 的 type 属性里。 + * 返回 false 表示这个连接器只以内嵌兄弟身份存在（由另一个连接器构造并持有）， + * 引擎不会为它建独立目录；它仍然参与服务发现与兄弟查找。默认 true。 + */ +default boolean isStandaloneCatalogType() { + return true; +} +``` + +目录创建流程改为：**先问插件（不带任何白名单）→ 再问引擎内建类型 → 都没命中才报错**。这个形状比现状严格更好：现在如果元数据镜像里存在一个不在白名单里的外部目录，重放（replay）会直接抛异常导致 **FE 起不来**；改后一律降级注册，首次访问时报错。 + +顺带说明一个副作用：白名单存在，使 `ConnectorProvider.supports(catalogType, properties)`（按属性而非仅按类型名分派的能力）**实际不可用**——目前 0 个连接器覆写它。删掉白名单后这个能力才真正激活。 + +#### （2）`CREATE TABLE` 的四处协同改动 + +新连接器要支持建表，今天必须在 `fe/fe-core/.../nereids/trees/plans/commands/info/CreateTableInfo.java` 改四个地方：目录类型到引擎名的 `switch`（`:918-926`）、引擎名白名单（`:954-976`）、分区与分桶子句的允许列表（`:1135-1145`），另有一处引擎名常量。代码注释 `:911` 自己写着「两个 switch 必须保持同步」——这是一个已知的、被记录下来的重复。 + +**建议**：把「本目录建表用哪个引擎名」下沉为连接器声明（返回空表示不支持建表），把「允许 PARTITION BY / DISTRIBUTED BY 子句」做成两个能力位。引擎侧的三处硬编码随之退化为读声明。这一批风险最高，必须靠端到端测试兜住——尤其要保持**校验的优先级顺序**，此前已有过把连接器内多阶段校验合并后丢掉优先级、导致建表用例失败的先例。 + +#### （3）扫描分片的格式路由键，中立默认值在 BE 侧没有分支 + +`ConnectorScanRange.getTableFormatType()`（`scan/ConnectorScanRange.java:113-122`）名义上是一个中立字符串，默认值是 `"plugin_driven"`。但 BE 侧对这个值是**白名单式**消费：`file_scanner_v2.cpp` 的两个判定函数各自维护一个已识别集合，不在集合里的值会被 V2 拒收、回落 V1，而 V1 的 reader 链没有无条件兜底分支，最终在 `file_scanner.cpp:1323-1329` 硬失败（"Not supported create reader for table format"）。也就是说**中立默认值在生产上是不可达的死值**：8 个连接器全部覆写了它。 + +**补检后这一条比上面写的更严重**（见附录 D.1）：BE 侧那条本该充当「插件通用逃生门」的 JNI 分支**自己也是封闭的**——`be/src/exec/scan/file_scanner.cpp:1081-1174` 的 JNI 分支内部是 6 段硬编码数据源名的 if-else，**既没有 else，也没有「按参数给我一个 JNI 读取器类名」的通用入口**；原生读取链同样是按源名的 if-else。所以一个新连接器要跑通**读路径**，今天必须改 `gensrc/thrift`（给共享 IDL 加按源的字段）+ `be/src/exec/scan/file_scanner.cpp` + 新读取器类（走 JNI 的还要加 `be/java-extensions` 模块并挂到共享类路径）。**这是本次调研发现的唯一真正的硬阻塞**：它不在 FE 侧，改不掉。 + +**建议**：不新增机制，改两件事——把方法从「带默认值」改成**抽象方法**（让「新连接器必须显式做这个决定」在编译期就显形），并在文档里写清「这不是自由字符串，取值必须属于 BE 已识别的集合，返回未识别值会在查询期硬失败，新增取值必须同步改 BE」，同时说明这是「BE 是 C++ 且无插件机制」的结构性后果，不是本接口能消除的。彻底修法（在 BE 的 JNI 分支加一个通用兜底，读取器类名与参数由属性表承载）投入产出不成立——树外连接器如果要复用某个已有读取器，直接返回那个读取器的名字就行。 + +### 4.2 软阻塞：连接器能跑，但拿不到与既有数据源同等的行为 + +这一层的共同形态是：`fe-core` 里用数据源**类型名字符串**做判定，新连接器不在名单里就静默拿不到某个行为。四处： + +| 位置 | 现状 | 后果 | 建议 | +|---|---|---|---| +| `MetastoreEventSyncDriver.java:119` | `!"hms".equalsIgnoreCase(type)` 决定是否为一个尚未初始化的目录做一次性强制预初始化以播种事件游标 | 新连接器即使实现了 `Connector.getEventSource()`，只要目录从未被查询过，事件源永远不会被激活。而 `Connector.getEventSource()` 的文档明确承诺「引擎的事件驱动完全与连接器无关，从不用 `instanceof`」——这句话在未初始化目录上是假的 | provider 上加 `providesEventSource()`（默认 false），引擎按它判定 | +| `FileQueryScanNode.CACHEABLE_CATALOGS:119` | 按目录类型白名单决定表是否纳入 BE 文件缓存的准入治理 | 新连接器静默绕过缓存治理 | 做成能力位（「本连接器的数据由 BE 原生文件读取器读取，参与文件缓存」） | +| `Env#changeCatalog:6509` | 硬编码 `"es"` → 切入 `default_db` | 新连接器无法声明「切换到本目录时自动进入某个默认库」 | provider 上加 `defaultDatabaseOnUse()`（默认空） | +| `DefaultConnectorContext#buildEnvironment:568-596` | FE 全局配置项逐键手工转发给连接器（9 个键，其中一处注释明写「键名必须与某连接器里的读取处逐字一致」）；`ConnectorSessionBuilder:222-233` 又另塞两个 | 新连接器要加一个可调参数，必须改 `fe-common` 的配置类、`fe-core` 的会话变量类，再在 `fe-core` 加一行手工转发 | 见 4.5 —— 这是一个更大的话题 | + +另外 `ConnectorScanProfile` 名义中立，但分组名必须匹配 `fe-core` 的 `SummaryProfile` 里按数据源硬编码的常量表，新连接器要输出扫描剖析信息就得改 `fe-core`。 + +### 4.3 不阻塞但仍是按类型分支的地方 + +`PluginDrivenExternalTable.getEngine()`（`:1275-1305`）与 `getEngineTableTypeName()`（`:1313-1330`）各有一张七项类型名 `switch`，用于保留迁移前的用户可见展示名。两张表**逐字重复**。 + +这一处**不建议下沉**：默认分支已经回落到通用值，新连接器零改动即可工作（不是阻塞）；消费者只做字符串拼接、不做枚举反查，所以它是纯展示。给连接器开一个「自选展示名」的自由度，代价是把兼容表从一处搬到七个连接器（净增代码）并引入误用面。**只建议把两张重复的表合并成一张，并加注释冻结它**（「翻闸前遗留展示名兼容表，新连接器不入表」）。 + +### 4.4 真正改不掉的结构性约束 + +这些不是缺陷，只应把边界写清楚，避免下一轮审查再把它们当问题提一遍： + +- **`fe-connector-api` 依赖 `fe-thrift`**，以及 `gensrc/thrift` 里按数据源开的联合体字段和 BE 侧的 `if` 链。**根因是 Doris 的 BE 是 C++ 且没有插件机制**：任何需要 BE 解释的负载都必须改 IDL 加 BE，中立字段名救不了这一点。Trino 能做到句柄完全不透明，是因为它的 worker 是 JVM，可以加载插件——这是根因差异，不是设计水平差异。 +- **`ConnectorCapability` 是封闭枚举这件事本身**。能力位的定义就是「引擎必须消费的开关」，一个没有引擎消费方的能力位毫无意义，所以新增一种能力必然涉及引擎改动。这不算可扩展性缺陷。真正该改的是它的**按表维度载体**（见主题二）。 +- **引擎名白名单里的内部表与已下线外部表类型**（`olap` / `mysql` / `odbc` / `broker` 等）：用户可见的遗留 SQL 语法，不能移除。 +- **构建脚本里的连接器模块名单**（`build.sh` 两处硬编码九个模块名）：可以改成目录通配（仓库里 `tools/check-connector-imports.sh` 已有先例），但 Maven 的 `` 必须显式列出，保留。 + +### 4.5 一个尚未排期、需要先拍板的落点：连接器自声明属性 + +`fe-connector-api` 里**已经有** `ConnectorPropertyMetadata` 这个类，以及 `Connector.getTableProperties()`（`:235`）和 `Connector.getSessionProperties()`（`:240`）两个取得器。这是从 Trino 直译过来的机制——在 Trino 里它是活的，直接支撑 `CREATE TABLE ... WITH (...)` 的合法键校验与 `SET SESSION 目录.属性 = 值`，连接器加一个可调参数**完全不碰引擎**。 + +在 Doris 这边，它**零实现零调用**（全仓库 15 处命中全在类自身和两个取得器内部）。实际通道是 4.2 表格最后一行那条手工转发。 + +这意味着一个真实卡点：**今天所有数据源专属旋钮只能落到 `fe-common` 的全局配置与 `fe-core` 的会话变量这条封闭路径上。** 把这两个已有接口接线成 Trino 那样的声明式属性，是「连接器加参数零公共模块改动」的正解，但它会改变 FE 配置项的用户可见位置（全局配置键变成按目录 / 按会话的属性），涉及兼容承诺——**需要单独决策，不宜和其它整治混在一起**。现存的六个数据源专属配置键都是迁移前既有的 `fe.conf` 名字，必须保留兼容。 + +如果决定不做，那么正确处置是**删掉这三个死接口**，并在设计文档里记下「未来若要做连接器自声明属性，这就是入口形状」——而不是让它们在公共接口里继续当装饰。 + +--- + +## 五、主题二：「声明一项能力」有多条并行通道 + +### 5.1 现象 + +一个连接器要告诉引擎「我支持某项可选能力」，今天有这些互不统一的通道： + +1. **能力枚举集合**：`Connector.getCapabilities()`（`:211`）返回 `Set`，13 个常量。 +2. **按表能力的逗号分隔字符串**：`ConnectorTableSchema.PER_TABLE_CAPABILITIES_KEY`（`:98`，键名 `__internal.connector.per-table-capabilities`），把能力名拼成 CSV 塞进表属性 `Map`。 +3. **写计划提供者上的布尔特性**，再在 `Connector` 上镜像一层空安全转发：`Connector.java:132/138/144/150/156/162/168/177/183` 共 9 个方法，方法体一律是「取 provider，为空返 false，否则转发」。 +4. **取得器返回 `null` 当能力探针**：`getScanPlanProvider()`（`:66`）、`getWritePlanProvider()`（`:93`）、`getProcedureOps()`（`:192`）、`getEventSource()`（`:347`）。后者的文档原文就写着「这是一个能力探针取得器」。 +5. **返回 `Optional` 表示「不支持」**：`ConnectorMetadata` 上 5 处，`Connector.schemaCacheTtlSecondOverride()`（`:359`）。 +6. **散落在各子接口上的 `supportsXxx()` 默认方法**：`ConnectorSchemaOps:58`、`ConnectorPushdownOps:72`、`ConnectorTableOps:172`、`ConnectorScanPlanProvider:89/250/268`。 +7. **窄标记接口 + 引擎侧 `instanceof`**：`WriteBlockAllocatingConnectorTransaction`、`RewriteCapableTransaction`。 + +经复核，这七条里**只有三条构成真正的冗余**，其余是不同形态的正当表达（值缺失用 `Optional`、子系统缺席用 `null`、能力开关挂在拥有它的子接口上——后者恰恰是应该收敛到的目标形态）。三条真冗余是： + +- **第 1 条与第 2 条是同一批能力的两条异质通道**（类型化集合 vs 字符串 CSV）。 +- **第 3 条的 11 个镜像方法与写计划提供者上的同名方法语义完全重复**（实测行号 `115/126/132/138/144/150/156/162/168/177/183`，其中 9 个返回布尔、2 个返回写操作集合）。 +- **第 4 条与第 5 条在同一个接口内用两种方式表达「不存在」**。 + +### 5.2 为什么是问题 + +**（a）字符串 CSV 通道没有任何编译期约束，拼错静默失效。** 而且这条通道**只对 13 个能力中的 5 个生效**：引擎只在 `PluginDrivenExternalTable.java:302` 的一个私有方法 `hasScanCapability` 里读 CSV，它的调用方只有 5 处；其余 8 个能力只读连接器级集合，完全绕过 CSV（`PluginDrivenExternalTable:337/353/438`、`PluginDrivenExternalCatalog:316/1289`、`PluginDrivenExternalDatabase:60`、`ShowPartitionsCommand:350`、`QueryTableValueFunction:78`、`CreateTableInfo:794`）。但接口文档承诺的是「任何能力都可以按表细化」。而 hive 网关会把兄弟连接器的**全部**能力反射进 CSV（`HiveConnectorMetadata.java:582`），多余的被静默丢弃。 + +一句话：**接口文档承诺 13/13，实现只兑现 5/13，而且没有任何地方记录是哪 5 个。** 同时 `hasScanCapability` 这个名字也是错的——它已经服务于 ALTER 列 DDL 与 ANALYZE，与「扫描」无关。 + +**（b）11 个镜像方法给同一个事实开了第二个可覆写入口。** 目前 0 个连接器覆写它们，所以没出事——但那是运气，不是设计保证。一旦某个连接器覆写了 `Connector.requiresParallelWrite()` 而没同步改写计划提供者，两个答案就会分叉，而这种分叉**没有任何测试能捕获**。 + +**（c）新连接器作者无法预判该用哪一套。** 根因很直接：**`fe-connector-api` 没有 `package-info.java`**（实测零命中），也没有任何地方写下「什么该放哪一层」。`ConnectorCapability` 的类文档只解释了一条边界（写操作与 sink 特性不放枚举、放 provider），而这条边界本身也是逐项拍的：`SUPPORTS_SORT_ORDER`（建表期的 ORDER BY 子句门）在枚举里，`requiresFullSchemaWriteOrder`（写路径的行序）在 provider 上，两者都属于「写能力」。 + +### 5.3 建议 + +**第一步（零风险，最该先做）：把规则写下来。** 新增 `fe-connector-api/package-info.java`，规定**三层且仅三层**： + +- **第一层「整块子系统有没有」**：`Connector` 上的 provider / ops 取得器，缺席用 `null`（引擎已按 `null` 判定，改 `Optional` 是纯变更噪音）。 +- **第二层「某块子系统内部的开关」**：该 provider 自己的 `supportsXxx()` / `requiresXxx()`，一律默认 false，引擎先拿到 provider 再问。**禁止在 `Connector` 上做镜像转发。** +- **第三层「引擎在拿不到 provider 时也必须问的静态规划开关」**：`ConnectorCapability` 枚举，且一律支持「连接器级 ∪ 按表级」的加法解析。凡是与某个 provider 一一对应的开关不得进枚举。 +- 「值缺失」用 `Optional`；「整块子系统缺席」用 `null`。这两者的区分写进规则。 + +**第二步：把按表能力从字符串升级为类型化集合。** 给 `ConnectorTableSchema` 加建造器与 `Set` 字段，删掉 CSV 键。已核实这个类**不参与 Gson 持久化**（只是进程内 schema 缓存值），没有兼容负担。同时把引擎侧 9 处直读能力集合的地方统一改走一个入口（`hasCapability`，实现为「连接器级 ∪ 本表级」），这样「哪些能力支持按表细化」从 5/13 变成 13/13，规则从「取决于引擎具体在哪读」变成「全部一致」。 + +**第三步：删掉 11 个镜像方法**，改为公共模块里的 `final` 静态派生器（真源唯一性由语言保证），并顺手补齐「7 个写特性只有 4 个有按表形态」的对称性缺口——按表形态是免费的，因为 `getWritePlanProvider(handle)` 默认就回落到连接器级。 + +--- + +## 六、主题三：大接口把互不相干的职责捆在一起 + +### 6.1 现状规模 + +| 接口 | 行数 | 方法数 | 混在一起的职责 | +|---|---|---|---| +| `ConnectorTableOps` | 504 | 46（全部有默认实现） | 表句柄解析 / 系统表 / 读 schema / 渲染建表语句 / 列句柄 /

个）/ 列分类 / 压缩类型调整 / 扫描节点属性（2 套）/ EXPLAIN 渲染 / 剖析信息 / thrift 参数填充 / 删除文件回读 / 序列化表回读 / 查询生命周期（释放读事务） | +| `Connector` | 362 | 34（1 个抽象） | 元数据工厂 / 三类 provider 取得器（各 2 个）/ 9 个写特性镜像 / 能力集合 / 存储属性派生 /

1 个批量）/ BE 文件类型 / broker 地址 / BE 存储属性 / BE 连通性探测 / 类型化存储属性 / 文件系统 / 空目录清理 | +| `ConnectorMetadata` | 235 | 自身 11 个，加上继承的六个 `Ops` 子接口共约 81 个 | 六个子接口 + 多版本快照 / 时间旅行 / 重写文件范围 / Top-N 延迟物化信号 | + +### 6.2 判断：哪些是真问题，哪些不是 + +**不是问题的部分（不要照抄 Trino 改回去）**： + +- **入口接口的聚合形状本身**。Trino 的 `Connector` 同样是「元数据工厂 + 若干 provider + 属性描述 + 生命周期」的聚合。要收的是**镜像转发和缓存失效那一族**，不是聚合本身。 +- **元数据接口很宽**。Trino 的 `ConnectorMetadata` 是 100 多个全默认方法的巨接口，靠文档告诉实现者「最少实现集」。所以 46 个全默认方法在这个坐标系里并不异常——**目标不是拆到多小，而是分域 + 每域写清最少实现集**。 + +**是真问题的部分**： + +- **`ConnectorTableOps` 里混着四组只有一个数据源用得上的方法**：分支与标签（4 个）、分区字段演进（3 个）、执行裸 SQL、透传查询取列。它们对其余连接器是纯噪音。 +- **`ConnectorScanPlanProvider` 混了三个不同抽象层次**：分片生成（连接器的核心职责）、能力开关（应属第二层规则）、以及 thrift 填充与「回读引擎刚写完的结构」这类协议细节。其中 `getDeleteFiles(TTableFormatFileDesc)` 让连接器去读**自己刚填进去的** thrift 子结构，`releaseReadTransaction(String queryId)` 把查询生命周期挂在一个「扫描计划提供者」上——这两个都是职责错位。 +- **`ConnectorContext` 上挂着 `sanitizeJdbcUrl`**：一个只有 JDBC 连接器用得上的方法，长在所有连接器共享的引擎服务接口上（见主题五）。 + +### 6.3 建议 + +有一个非常有利的事实：**`ConnectorTableOps` 在全仓库没有任何一处被当成静态类型使用**——只出现在注释与文档链接里。这意味着**把它按域拆成多个父接口是零破坏重构**：连接器一行不改、编译期完全兼容。这是整套整治能分批落地的最大杠杆。 + +建议的形状： + +- `ConnectorTableOps` 按域拆成 6 个父接口（表基础 / 视图 / 表级 DDL / 列演进 / 快照引用管理 / 分区列举），`ConnectorTableOps` 保留为它们的聚合，**每个父接口的类文档写清「最少实现集」**。零破坏，可当天合入，并为后续每一批划定域边界。 +- `ConnectorScanPlanProvider` 拆三层（分片生成 / 能力开关 / 协议填充），收敛 4 个 `planScan` 重载（现状是引擎只调最宽的那个，而抽象方法是最窄的那个，导致连接器出现**不可达的覆写**）。 +- `ConnectorContext` 把存储相关的 9 个方法收成一个服务对象。**这一批高危**：iceberg 与 paimon 各有一个逐方法转发的包装类，用于把线程上下文类加载器钉到插件加载器上；改动必须做插件包重部署冒烟验证。 + +--- + +## 七、主题四：没有调用方或没有实现方的接口面 + +### 7.1 为什么这件事比看起来严重 + +死接口面的成本不是占空间，是三种真实伤害： + +1. **强制实现的死方法在向每个新连接器收税。** `ConnectorScanRange.getRangeType()` 是抽象方法，8 个连接器全部实现了它，返回值全仓库无人读取。连 `fe-core` 的 4 个测试匿名类都得为满足这个抽象方法写一遍实现——这就是它的传染成本证据。 +2. **文档错误制造排查浪费。** `ConnectorScanRangeType` 的文档说「引擎据此选择 thrift 结构」，这是错的（真正决定的是 `populateRangeParams` 的多态覆写与格式类型）。一个连接器作者改了这个枚举发现不生效，会去查引擎，查不到。 +3. **有的死接口留着比删掉危险。** `ConnectorPushdownOps.applyLimit` 零实现，而它的调用时机（在残余谓词构建之前）**绕过了「剥离隐式类型转换时禁止把 LIMIT 下推到数据源」这条安全抑制**。哪天有人实现了它，就会得到错误结果。 + +### 7.2 可以直接删（纯公共模块内部，零实现零调用零持久化） + +以下每一条都经过全仓库重扫确认（含 `fe-core`、8 个连接器、测试、be-java-extensions、服务发现配置与反射字符串）： + +| 删除对象 | 依据 | +|---|---| +| `ConnectorPropertyMetadata` 整类 + `Connector.getTableProperties()` + `Connector.getSessionProperties()` | 全仓 15

+| 位置 | 现象 | 建议 | +|---|---|---| +| `Connector.executeRestRequest`（`:303`） | REST 透传逃生门，文档写「例如 Elasticsearch」。唯一实现方是 ES，唯一调用方是一个按类型名 `=="es"` 硬判的 REST 端点 | 摘成独立可选接口，由 ES 连接器实现。**那个 REST 端点自己的类型判定不动**——它本身就是 ES 兼容 API，按类型收窄是正确边界；缺陷在于把 ES 形状的方法挂在所有连接器都继承的入口接口上 | +| `ConnectorContext.sanitizeJdbcUrl`（`:79`） | JDBC 地址消毒长在中立的引擎服务接口上，且「使用任何 JDBC 地址前必须调用」的契约只有 JDBC 连接器遵守——iceberg 与 paimon 的 JDBC 元存储把用户地址直接交给第三方 SDK 建连 | 改名为中立的出站地址消毒，契约收口为「连接器**自行**建立连接时必须调用；第三方 SDK 内部建连不在覆盖内」。另可作为独立安全增强给 iceberg / paimon 补调用 | +| `ConnectorPartitionValues.HIVE_DEFAULT_PARTITION` | 公共接口里唯一的数据源品牌字符串常量，且中立命名的 `normalize()` / `isNullPartitionValue()` 只有 hive 语义成立 | **常量不删不改值**（它是分区名身份与 BE 列路径解析的字节兼容基础，物化视图与表函数已持久化这些名字），只做中立化命名 + 保留旧名别名一轮；把带 hive 与 hudi 语义的三个归一方法**下沉到唯一的生产调用方**（hudi 连接器） | +| `ConnectorScanRange.isNativeReadRange()` | 名字中立，存在的唯一目的是拼某个连接器的 EXPLAIN 行，且只有它实现 | 去掉文档里的源专属键名，或按需下沉 | +| `ConnectorScanPlanProvider.getSerializedTable(Map)` | 名字通用、语义未定义，实现只是把自己写进属性表的一个源专属键原样取回 | 定义清楚或下沉 | +| `ConnectorValidationContext.requestBeConnectivityTest` | 名义中立，实质只能是 JDBC：字节数组里偷运一个 JDBC 表结构，整数是另一个枚举的序号 | 补文档说清载荷契约；结构性中立化需跨 thrift 与 BE，不属本轮 | + +### 8.2 第二类：名字中立，但语义只对一个数据源成立（更危险） + +- **`ConnectorWritePartitionField`**：`transform` 是某个数据源分区变换的 `toString()` 文本，`fe-core` 直接字符串比对 `"identity"`，`sourceId` 字段的文档自称是那个源的字段编号。**但这不能简单合并或改值域**——已核实 BE 侧用正则解析带括号的形式（如 `bucket[16]`）并直接做字符串比较，FE 把该串**原样**塞进 thrift。所以「变换串含参数又并列一个参数字段＝冗余」这条不成立，那是 FE 与 BE 有线格式的镜像。可做的是：在公共模块定义词表常量与 `isIdentity()`，把有线格式写进文档，让 `fe-core` 不再出现裸字面量比较。 +- **`BranchChange` / `TagChange` / `DropRefChange`**：字段集是某个数据源快照引用模型的一比一映射（含快照 id 与三个保留期旋钮），却挂在所有连接器共享的表操作接口上。建议把字段名改成 SQL 级中立名（对齐公共 SQL 语法里的用词），**不建议**把快照 id 改成不透明类型——可表达性上限由公共 SQL 语法决定，改接口不增加任何表达力。 +- **`event` 包**（`MetastoreChangeDescriptor` / `ConnectorEventSource` / `EventPollRequest` / `EventPollResult`）：整包是某种元存储通知日志模型的中立包装（单调递增的长整型事件游标），唯一实现者就是那个元存储。**不建议改类名或把游标改成不透明字符串**：游标是长整型这个形状是引擎侧编辑日志与主从上界收敛共同决定的，改类型要先解决编辑日志兼容和「不可比较的游标如何算从节点上界」。本轮只在文档里写清「游标必须是可比较的数值 id」这条前置假设。 +- **`ConnectorMetadata.applySnapshot`** 的公共契约把某个数据源专有的扫描选项键写成了中立接口的回退规则，公共模块自带单测也硬编码了那个键名。建议改成「连接器自行决定如何承载，接口不规定任何选项键名」。 +- **`ProcedureExecutionMode.DISTRIBUTED`** 的结果 schema 被硬编码成某个数据源某个过程的四列（在 `fe-core` 的 `ConnectorRewriteDriver` 里）。建议把结果 schema 交还连接器（与单次调用模式对称），引擎只负责编排并把每组统计原样回传。 +- **`SUPPORTS_NESTED_COLUMN_SCHEMA_CHANGE`** 的语义被定义为「某个数据源风格的 schema 变更子句集」——中立名字承载单源定义。只需改述文档。 +- **`ConnectorSession.getSessionId`**、**`ConnectorContext.vendStorageCredentials`**、**`ConnectorDelegatedCredential.Type`** 的文档把某个数据源的认证/SDK 语义写成了唯一动机。纯措辞问题，一次性文档批处理。 + +### 8.3 第三类：通用引擎代码里残留的数据源分支 + +`fe-core` 的通用扫描节点 `PluginDrivenScanNode` 里还有 ES 专属分支：`:559-563`（EXPLAIN 输出某个 ES 参数）与 `:1829-1835`（往 ES 专属属性里塞 limit）。这违反了「通用节点保持与连接器无关」这条既定纪律，而且**接口侧已经有承接点**——ES 的扫描计划提供者已经覆写了 EXPLAIN 追加与扫描级参数填充两个方法。建议搬进连接器，把引擎侧需要的三个判据（下推的 limit、是否所有过滤都已下推、批大小）以中立的合成键传入（同文件已有这套机制的先例）。 + +--- + +## 九、主题六：抽象泄漏 —— 两套相反的 thrift 规则 + +这是本轮我认为**最值得单独拎出来**的一致性问题，因为它不是某个方法的瑕疵，而是两个公共模块在同一个问题上采用了相反的规则。 + +**`fe-connector-spi` 刻意避开 thrift**： +- `ConnectorContext.getBackendFileType(...)` 返回**枚举名字符串**（如 `"FILE_S3"`），文档明写「返回枚举名（一个普通字符串）以使本接口保持 thrift-free，连接器自己映射回去」。 +- `getBrokerAddresses()` 返回中立的 `ConnectorBrokerAddress` 主机端口对，而不是 thrift 的网络地址结构，理由同上。 +- `testBackendStorageConnectivity(int storageBackendTypeValue, ...)` 更进一步——把一个 thrift 枚举**的整数值**当参数传。 + +**`fe-connector-api` 完全不避**： +- `ConnectorScanPlanProvider` 直接 import 三个 thrift 生成类（`TFileCompressType`、`TFileScanRangeParams`、`TTableFormatFileDesc`）。 +- `ConnectorScanRange` import 两个（`TFileRangeDesc`、`TTableFormatFileDesc`）。 +- `ConnectorSinkPlan` 以 `TDataSink` 为核心，`ConnectorWriteHandle` 用 `TSortInfo`。 +- `ConnectorTableOps.buildTableDescriptor` 返回 `TTableDescriptor`，而且是用**内联全限定名**写的（`ConnectorTableOps.java:464`）——这种写法本身就是「知道这里不该出现它」的痕迹。 + +**后果**：一个新连接器作者读 `spi` 会以为「公共接口不碰 thrift，引擎会用中立类型和我交互」，读 `api` 会发现自己必须直接构造引擎的 thrift 对象。两种预期在同一次实现里冲突。而 `spi` 那条「thrift-free」的规则也没有真正兑现——它的整数参数形态其实是**比直接用类型更差的耦合**：丢了类型安全，还是绑死了枚举取值。 + +**建议**：接受「面向 BE 的负载必须走 thrift」这个结构性事实（根因是 BE 是 C++ 且无插件机制），但把规则统一写下来，放进 `fe-connector-api/package-info.java`： + +- 明确 thrift 只允许出现在**面向 BE 的协议边界**上（分片参数、数据 sink、表描述符），并列出当前的完整清单； +- 明确**不再新增** thrift 入参的方法； +- 把 `spi` 侧那三处「为了 thrift-free 而做的字符串/整数化」的理由写清，或者反过来——既然 `api` 已经依赖 thrift 而 `spi` 又依赖 `api`，那这三处的字符串化收益为零，可以考虑统一； +- 三处可行的纯值搬运中立化（压缩类型调整、写句柄的排序信息、`getDeleteFiles` 改成 `ConnectorScanRange.getDeleteFilePaths()`）属于低优先的洁净化，可排在后面或不做。 + +--- + +## 十、主题七：语义与契约不清 + +### 10.1 用字符串表把结构化信息偷运过边界 + +三处，都违反「不应用 `Map` 偷运结构化信息而不定义键契约」： + +**（a）`ConnectorTableSchema` 的保留键。** 7 个 `__internal.` 前缀键承载：分区列、主键、按表能力集合、分布列，以及三段**预渲染的 Doris SQL 片段**（位置、PARTITION BY 子句、ORDER BY 子句）。前四个应该类型化（见主题二）。后三段**建议保留在属性表**：让连接器预渲染确实把 Doris 的反引号规则泄漏进了插件，但把它搬回引擎就要求引擎理解各数据源的变换语法，直接违反「引擎不解析属性」的既定架构目标。这是有意取舍，只应在文档里写清「连接器负责按 Doris 反引号规则转义」。 + +**（b）扫描节点属性表。** `ConnectorScanPlanProvider.getScanNodeProperties` 返回 `Map`，但**键的契约不在公共模块**——一半散在 `fe-core` 的私有常量里（`PluginDrivenScanNode.java:127-130`，其中还有带数据源名前缀的键），一半散在各连接器的字面量里。新连接器只能靠读引擎源码抄字符串。建议在公共模块建一个键常量类，把契约集中并公开。 + +**（c）`ConnectorWriteHandle.getWriteContext()`。** 用无键契约的字符串表偷运静态分区值，方法名与内容不符——**它自己的文档都承认了这一点**。 + +### 10.2 数值的单位与「未知值」没有统一约定 + +- **`ConnectorScanRange.getLength()`** 文档写「字节数」，但 MaxCompute 在按行偏移的模式下返回**行数**，而引擎无条件把它累加进「总文件大小」。这是一个已知的项目级事实（分片长度的语义因连接器而异），正确的处置不是统一语义，而是**按大小的通用特性必须走能力 opt-in**，并把文档改成据实描述。 +- **`ConnectorMvccSnapshot.getSnapshotId()`** 没有定义「未知 / 无快照」的取值：建造器默认 0，而引擎的空 pin 判定与某连接器的统计逻辑都按 `-1` 或 `< 0` 判断。只带属性的 pin 会静默拿到 0。 +- **`ConnectorPartitionInfo.lastModifiedMillis`** 契约是 epoch 毫秒，hudi 填的是它自己的时刻串（`yyyyMMddHHmmssSSS` 形式的数字）。**这是一个有实际后果的缺陷**：引擎拿它与墙上时钟相减做 SQL 缓存的窗口门禁，非 epoch 毫秒会让这类查询的 SQL 缓存**永久不启用**（「永久」的机制是引擎把当前时间与这个更大的数取最大值，于是差值恒为 0，不是「等一会儿就好」）。**影响面（后续核实后收窄）**：仅在会话开关打开、且表是**分区** hudi 表时可见（无分区 hudi 表的版本令牌本来就是 0、本来就不可缓存）。修法在连接器侧（转换成 epoch 毫秒），引擎零改动；注意时刻串不带时区，按表配置的时区生成，转换时要读表配置而不是用全局时区。 +- **统计接口的「未知」有三种表达**（`Optional.empty()` / `UNKNOWN` 常量 / 特殊数值），其中 `UNKNOWN` 常量零使用且与接口约定矛盾。 + +### 10.3 异常契约缺失 + +`DorisConnectorException` 只是一个空壳基类，公共模块**没有定义异常契约**。实际上连接器混用四个异常族，而引擎只翻译其中一族。表现出来的具体问题： + +- `resolveTimeTravel` 的契约写「不支持的规格返回空」，三个连接器全部改为**抛异常**，且异常类型三家不一致。 +- `listFileSizes` 的契约明确写「出错必须返回空、不得抛异常」，**唯一实现故意抛出，并有单测锁死抛出行为**。这一条经核实**实现是对的、文档是错的**：显式的采样分析必须 fail loud，吞掉异常会让采样因子静默塌成 1.0，产出错误的统计。 +- `ConnectorProvider.create()`（无参版，`:93`）为满足插件工厂的类型上界而存在，实现是无条件抛异常——违反父接口契约。目前不可达，最小处置是标注过时 + 文档写明「任何调用都是错误用法」。 + +**建议**：在 `package-info` 里定义异常分层（用户错误 / 配置错误 / 远端不可用 / 内部错误），规定连接器一律抛 `DorisConnectorException` 的子类，并给出「什么时候该 fail loud、什么时候该静默降级」的判据。这比逐个方法补文档更有效，因为它给的是规则而不是个例。 + +### 10.4 生命周期与线程模型没写进契约 + +- **`Connector.getMetadata` 返回的实例**：引擎按「每语句一实例、语句结束时关闭」使用，但契约没写；同时 `ConnectorMetadata.close()` **没有任何连接器实现**（共享客户端由 `Connector.close` 释放）。建议在两处交叉写清「每语句一实例、语句结束由引擎关闭、关闭必须幂等、单实例不跨线程共享」，并互相引用到语句作用域类。 +- **统计接口在引擎的后台统计线程上被调用，而引擎不钉线程上下文类加载器**——公共接口完全没写这个契约，唯一的实现靠自己补救。这在本项目里是一类已知的高危坑（跨插件类加载器的按名反射）。必须写进契约。 +- **`ConnectorStatementScope` 关闭后的状态未定义**，实现允许「关闭后复活」，此后写入的可关闭值永远不会被关闭。 + +### 10.5 方法名与行为不符 / 重载堆叠 + +- `ignorePartitionPruneShortCircuit()` 是双重否定命名。 +- `ConnectorType` 这个名字指的是**数据类型**（"INT" / "DECIMAL"），不是「连接器的类型」。这个命名会让每个第一次读代码的人误判（我自己就误判了一次）。改名成本已不可承受（同一词表被下推侧、schema 映射侧与引擎反向构造三方共用），**只补文档**。 +- `ConnectorType` 用 7 个构造器（6 个便捷 + 1 个规范）+ 9 个静态工厂 + 5 组平行列表承载可选元数据，且 `equals` 只覆盖其中一部分（这一点是有意的、文档也写清了，不算缺陷）。 +- `planScan` 四级望远镜重载：引擎只调最宽的一个，抽象方法却是最窄的那个。 +- `getScanNodeProperties`（返回 `Map`）与 `getScanNodePropertiesResult`（返回包装对象）两个面：引擎只调后者，6 个连接器只实现前者并经默认委派生效。**这不是两套竞争机制**（后者的默认实现显式包装前者），但**同时覆写两者会静默丢掉一个**——必须补一句文档，并把包装对象「用调了哪个构造器」隐式编码一个布尔位的做法改成两个具名静态工厂。 + +--- + +## 十一、主题八：实现与接口定义不符 + +这一节回答用户提出的第二个问题（「实现是否符合接口定义」）。共 24 条，分四类。 + +### 11.1 四个有实际用户可见后果的缺陷 + +**（1）三路以上的 OR 谓词在某个连接器上会丢行。** `ConnectorOr` 被文档化为 N 元（`getDisjuncts()` 返回列表），但 trino 连接器的谓词转换器只读**前两个** disjunct（`TrinoPredicateConverter.java:114-118`）。`WHERE a=1 OR a=2 OR a=3` 会在数据源侧按 `a=1 OR a=2` 过滤——**结果少行**。修法：按列做域并集折叠全部 disjunct；同时给 `ConnectorOr` 构造器加「至少两个」校验与防御性拷贝。 + +**（2）复杂类型的字段名会被丢掉，引擎静默编造替代名。** `ConnectorType` 的字段名列表与子类型列表是两条平行列表，两者的对应关系**既没有契约也没有校验**（构造器不校验长度）。trino 连接器构造 STRUCT 时丢掉了字段名，引擎侧于是编造 `col0` / `col1`。修法：构造期校验，并在文档里把平行列表的对应关系写成契约。 + +**（3）`WHERE 列 <=> 5` 这种空值安全比较会被 paimon 下推成「该列 IS NULL」。⚠ 后续核实：这条默认潜伏，不是默认可观察。** + +先说这个重要更正：优化器有一条改写规则（`NullSafeEqualToEqual`），在**过滤条件位置**只要一边不可为空（字面量恒不可为空）就会先把 `列 <=> 5` 改写成 `列 = 5`（判据在该类的 `canConvertToEqual`：`(!left.nullable() && !right.nullable()) || (isInsideCondition && (!left.nullable() || !right.nullable()))`）。所以普通的 `WHERE c <=> 5` 通常到不了连接器的坏分支。该规则带可禁用标签，通过会话变量关掉它之后才会走到坏分支——这条复现路径是按代码推导的，**未起集群实跑验证**。 + +因此正确的定性是：**缺陷客观存在且严重（一旦到达就静默少行），但默认被优化器改写挡住，属潜伏缺陷。** 它仍然必须修——连接器的正确性不能依赖一条可以被关掉的优化规则。下面是缺陷本身： 比较算子枚举的公共契约总共只有一行文字（`pushdown/ConnectorComparison.java:27` 列出七个算子名），**没有任何地方说明右操作数可能是空值字面量、空值安全比较的语义、以及不可精确翻译时必须放弃下推（不得收窄）**。于是五个消费者各写一遍：iceberg 做对了并写了注释，trino 做对了，maxcompute 显式放弃，es 有专门测试——**只有 paimon 错了**：它先把空值字面量过滤掉（`PaimonPredicateConverter.java:245-247`），于是 `:173-174` 的空值安全分支**只可能在字面量非空时到达**，`WHERE c <=> 5` 被翻成 `c IS NULL`，paimon 据此做文件级裁剪，`c=5` 所在的数据文件被跳过——**静默少行，且 BE 复算补不回来**。 + +**（4）含单字符通配符或转义的 LIKE 谓词会被 paimon 收窄成前缀匹配，也会少行。** `ConnectorLike` 的全部契约就是一句「值 LIKE 模式」（`pushdown/ConnectorLike.java:23-24`），**没有**转义字符、`%` 与 `_` 的方言、正则是部分匹配还是整串锚定、大小写敏感性。paimon 于是只要「不以 `%` 开头且以 `%` 结尾」就转成前缀匹配（`PaimonPredicateConverter.java:233-238`），对 `_` 与被转义的 `%` 没有任何守卫——`LIKE 'a_c%'` 变成 `startsWith("a_c")`。ES 那侧则把 Doris 的正则原样交给 ES 的正则查询，而两者的锚定语义不同。 + +**这四条的归责（后续逐条核实后修正）**： + +- **（1）是本次迁移引入的回退**，不是上游既有缺陷。迁移前的实现在它自己的二元谓词模型下是正确完备的；缺陷来自迁移把输入换成了 N 元列表，却照抄了「读两个孩子」的写法。（上游 `master` 上也已存在同样写法的连接器文件，由迁移早期的一个 PR 带入，但 `master` 上迁移前的旧路径仍在，所以只有本分支这段是生效路径。）**提交信息里不得把它描述成上游既有缺陷。** +- **（2）是本次迁移引入的**（同一处类型映射在迁移前会判断字段名是否存在）。附带一点：迁移前对匿名字段一律用同一个名字、本身会重名，所以修复时用「名字 + 下标」是**有意偏离**迁移前行为的改进，不是平价移植。 +- **（3）（4）是 paimon 连接器的问题，经 `git show master` 逐字对比确认与上游既有实现完全相同——是上游既有缺陷的忠实移植，不是本次迁移引入的回退。** + +另外，（4）的行为后果是代码路径推断、未跑端到端验证；后续核实还发现**第三种同根因形态**：`%` 夹在模式串中间（例如 `LIKE 'a%b%'`）现在也会被当成字面前缀下推。所以修法要收紧为「含 `_` 或转义符直接放弃；剥掉末尾连续 `%` 之后主体仍含 `%` 或为空则放弃」。 + +但对本次调研而言，共同点是：**接口没有校验、没有契约，就是让这类实现错误能活下来、并且四家连接器各写一遍各错一遍的原因**。公共接口该做的是把逐算子语义与「不可精确翻译必须返回不下推」写进契约；连接器侧的两个 bug 另开修复并配端到端回归。 + +### 11.2 文档描述的用途与真实用途完全不同（文档陈旧） + +| 方法 | 文档说 | 实际 | +|---|---|---| +| `ConnectorTableOps.listPartitionValues` | 服务分区值表函数 | 零生产调用方；那个表函数走 `listPartitions`（`PluginDrivenExternalTable.java:898-899`） | +| `ConnectorScanRangeType` | 引擎据此选择 thrift 结构 | 引擎从不读它；真正决定的是参数填充方法的多态覆写 | +| `ConnectorEventSource.getCurrentEventId` | 引擎用它先探测有没有新事件再拉取 | 零调用；游标完全由拉取结果驱动 | +| `ConnectorContractValidator` | 「由每个连接器的契约测试调用 validate 来强制」 | 只有 4 个连接器的测试调用；**唯一声明了分区哈希写的 hive 恰好没调**，导致相关不变量在生产连接器上没有正样本。另外它只校验连接器级形态，而引擎读的是按表形态 | +| `ConnectorProcedureOps.getSupportedProcedures` | 引擎用它做路由与校验 | 两项都不成立：路由走执行模式，未知名拒绝由连接器在执行方法内完成；唯一读取点自身无生产调用方 | +| `ConnectorPartitionInfo` | 「不填分区值则引擎回退解析分区名」 | 引擎侧的回退已被删除、改成了元数（arity）硬校验，且调用方的 try/catch 把失败降级成「整表无分区」 | +| `ConnectorMvccSnapshot` | 「会被序列化进 BE 的扫描分片」「属性会传播到 BE」 | 引擎两件事都不做（由连接器自己的扫描计划提供者送达） | +|

只对残余谓词路径成立；`applyFilter` 路径**不剥**。而三个实现 `applyFilter` 的连接器都继承了**不安全的默认 true** | + +最后一条需要人拍板：建议**把默认值改成 false（安全侧）**，让连接器显式声明自己能正确处理隐式类型转换的谓词语义，并把文档改成据实描述两条路径的差异。彻底修法需要在引擎侧给被剥壳的比较打标记，让连接器能自查——因为表达式模型里**没有类型转换节点**，剥壳发生在引擎侧，连接器目前无从自查。 + +### 11.3 契约被实现违背 + +- `listFileSizes` 的异常契约（见 10.3，**实现对、文档错**）。 +- `resolveTimeTravel` 的「返回空」通道（见 10.3，**实现对、文档不完整**——引擎侧只有「未找到」一种用户文案，空值无法表达「语法不支持」，所以抛异常是必要的；应把这条写进契约）。 +- `sanitizeJdbcUrl` 的「必须调用」契约只有一个连接器遵守（见 8.1）。 +- `ConnectorContext.getHttpSecurityHook` 的用法契约（对外 HTTP 前后调用）也只有一个连接器遵守，iceberg / paimon 的 REST 目录用用户提供的地址发 HTTP 却不过这个防护钩子。 +- `ConnectorTransaction` 契约声明回滚与关闭可重复调用，hive 实现不满足（二次回滚会在已关闭的线程池上再提交任务）。 +- `ConnectorSchemaOps` 的库名参数在兄弟方法之间**一个是本地名一个是远端名**，文档完全没约定。 +- `listPartitions` 的过滤参数在生产中恒为空，却被三个连接器重新解释成「绕过缓存」的开关。 +- `WriteOperation.UPDATE` 从来不是可声明的写能力：无连接器在支持集合里声明它，引擎准入只查删除或合并——**只支持删除的连接器会被放行执行更新**。 +- `getUpdateCnt()` 契约只写「受影响行数」，但引擎依赖一个未在接口上定义的 `-1` 哨兵（只写在某个默认实现的类注释里）。 +- EXPLAIN 路径传给写侧 EXPLAIN 方法的写句柄是**伪造的**（覆写标志恒 false、上下文恒空、排序信息恒 null），接口文档未告知。 + +### 11.4 按表能力 CSV 的静默丢弃（见主题二） + +补一个实现细节，它是这一簇里最关键的：**「未知能力名」要分两种**——不是任何合法能力常量名的 token（纯拼写错，必然是 bug，应抛异常）vs 是合法常量但不在可细化子集里（hive 有意反射兄弟连接器全集，必须静默忽略）。只有区分这两者，才能既 fail loud 又不破坏异构网关。 + +--- + +## 十二、主题九：对称性缺口 + +- **写特性的按表形态只做了 7 个中的 4 个**。异构网关拿不到另外 3 个的按表答案，注释里自陈「靠两边恰好都为 true 侥幸成立」。按主题二第三步的做法，这个缺口是**免费**补上的。 +- **hive 网关为 12 个 DDL 转交了 iceberg 兄弟，却漏了 5 个按路径寻址的列 DDL**（含唯一入口 `modifyColumnComment`）——后果是 Hive 元存储目录里的 Iceberg 表上 `MODIFY COLUMN COMMENT` 直接不可用。这是实现缺口，不是接口缺陷，但值得单独修。 +- **列统计只有「单列、无快照」一种形态**：表统计有带快照的重载而列统计没有，且底层的批量能力被包成逐列往返。 +- **建表请求没有主键字段**：paimon 只能从属性表里偷运主键，而读侧却有一个一等公民的 `getPrimaryKeys()`（它自己又是死接口）。 +- **`apiVersion` 不匹配在两条引擎路径上行为相反**：一条告警后静默跳过，一条直接抛。 +- **「改写表句柄」的一族方法分裂成两种返回约定**，且 `applySnapshot` 的文档声称与 `applyFilter` 同构，实际不同构。 + +--- + +## 十三、主题十：`api` 与 `spi` 两个模块的边界说不清 + +这一条是我自己在通读时发现的，也是完备性核查要单独确认的一项。 + +**事实**：`spi` 依赖 `api`（单向，方向本身是清晰的）。`api` 的模块描述说自己是「面向消费方的 API：核心 Connector 接口、元数据子接口、不透明句柄、会话、值对象、能力枚举」；`spi` 的包文档说自己是「连接器实现必须履行的 SPI 契约，主入口是 `ConnectorProvider`」。 + +**问题**：这个划分说不清，且现状自相矛盾。 + +- 如果边界是「谁实现」：`spi` 放「引擎实现、连接器消费」的东西（`ConnectorContext`、`ConnectorMetaInvalidator`、`ConnectorBrokerAddress`）+ 服务发现入口（`ConnectorProvider`），`api` 放「连接器实现、引擎消费」的东西。**但这条规则被大量违反**：`ConnectorSession`（引擎实现、连接器消费）、`ConnectorHttpSecurityHook`（引擎实现）、`ConnectorValidationContext`（引擎服务）全在 `api`。 +- 如果边界是「thrift 洁净度」：`spi` 声称 thrift-free，但它依赖的 `api` 就依赖 `fe-thrift`（见主题六），所以这条也不成立。 +- 实际效果上，两个模块**总是同时出现在连接器的编译类路径上**，也都被编进 `fe-core`，所以这个拆分**没有带来任何可强制的依赖约束**——它今天只是一个命名约定。 +- **更进一步：两个模块的名字与内容整体是反着的。** 按业界惯例（也是 Trino 的用法），「连接器要实现的东西」叫 SPI，「连接器要消费的引擎服务」叫 API。而这里 `fe-connector-api`（95 个文件）装的是**连接器要实现**的接口，`fe-connector-spi`（5 个文件）装的是**连接器要消费**的引擎服务。所以问题不只是「某个类放错边」，是两个模块名整体倒置。 +- `fe-connector-spi/pom.xml:38` 的模块描述里写着它「包含 `ConnectorProvider`、`ConnectorContext` 和 `ConnectorTypeMapper`」——**`ConnectorTypeMapper` 这个类全仓不存在**（唯一命中就是这行描述本身）。陈旧描述。 +- 边界没有任何机器校验：`tools/check-connector-imports.sh` 里不含任何关于「什么该放 api、什么该放 spi」的规则。 +- 依赖方向本身**已核实无问题**：`api` 不 import `spi`（实测零命中），`spi` → `api` 单向；`fe-thrift` 在 `api` 里是 `provided`、不传递。但「`spi` 没有引擎类型」这句只对 thrift 成立——`spi` 依赖 `fe-filesystem-api`，把文件系统类型递给连接器，性质与 thrift 同类（只是那是有意的内部 API 边界）。 + +**另外，缓存失效这件事被这个边界切成了两半，而且方向相反**： + +- `api` 侧：`Connector.invalidateTable / invalidateDb / invalidateAll / invalidatePartition`——引擎通知连接器丢缓存。**这套是活的**（引擎侧 16 处调用）。 +- `spi` 侧：`ConnectorMetaInvalidator`——连接器通知引擎丢缓存。**这套零连接器调用，且引擎侧履约不了它的契约**：按分区失效传的是分区列值而引擎缓存按分区名索引，只能降级成整表；统计失效没有入口，是空操作。真正在跑的是拉模型（连接器暴露事件源 + 引擎轮询后自行失效）。iceberg 的测试注释已明确记载「连接器侧通知曾被有意移除」。 + +**建议**： + +1. **给两个模块各写一份 `package-info`，把边界规则写下来**，并按规则把放错位置的类型归位（或者明确承认这个划分只是历史产物、以「谁实现」为准并逐步归位）。 +2. **删掉 `ConnectorMetaInvalidator` 这套死的推模型**（连带引擎侧实现与两个包装类的转发），只留拉模型。这样「失效」这件事只剩一个方向、一套词汇。 + +--- + +##

+--- + +## 十六、明确不建议动的部分 + +这一节和上一节同等重要——它防止下一轮审查把同样的东西再提一遍。 + +1. **展示名兼容表**（主题四第 4.3 节）：只合并去重 + 加注释冻结，不下沉。 +2. **ES 兼容 REST 端点自身的类型判定**：那个端点本身就是 ES 形状的 API，按类型收窄是正确边界。缺陷只在于把 ES 形状的方法挂在共享入口接口上。 +3. **数据类型的 token 词表**（`DECIMALV3` / `DATEV2` / `DATETIMEV2` 等）：同一词表被下推侧、schema 映射侧与引擎反向构造三方共用，改名会造成两套词表分叉。只补文档。 +4. **`ConnectorCapability` 封闭枚举本体**：能力位必须有引擎消费方，新增能力必然涉及引擎改动，这不是缺陷。 +5. **预渲染的三段建表语句片段**：搬回引擎会违反「引擎不解析属性」的既定架构目标。只补文档说清转义责任。 +6. **公共模块依赖 `fe-thrift` 与按数据源开的 thrift 联合体**：根因是 BE 是 C++ 且无插件机制。只写清边界。 +7. **写侧与建表侧的分区/排序值对象不合并**：生命周期与标识空间不同，且写侧是 BE 有线契约的直接镜像。该做的是中立化文档与命名对齐。 +8. **两个单字段谓词包装类（读侧与写侧）不合并**：null 契约相反是有单测显式覆盖的有意设计。该做的是删掉公共文档里的内部工单号、补上第二条生产路径的说明、并写清「写侧谓词可能比用户的 WHERE 更宽」。 +9. **两套残差谓词协议不合并**：下标协议是当前唯一真正生效的，残差协议在引擎侧被实现成「什么都不摘」（细粒度反查标为未来增强）。合并需要先实现细粒度反查。该做的是补文档。 +10. **分区空值哨兵的字符串值**：物化视图与表函数已持久化这些名字，BE 的列路径解析也依赖它。只改命名与归属，不改值。 +11. **事件游标是长整型这个形状**：由引擎编辑日志与主从上界收敛共同决定。只写清「游标必须可比较」。 +12. **`ConnectorMetadata` 的 `Closeable` 面**：9 个实现全不覆写，但语句作用域的关闭逻辑本身并非空转。删掉会关闭一个将来必然需要的扩展点，只补幂等契约。 +13. **`ConnectorContractValidator` 不删也不搬进引擎**：它不是死代码，而是被有意限定在契约测试里调用的静态断言工具（不在目录注册期跑有客观理由：读写能力检查会构造写计划提供者，某连接器会提前建远端目录）。真正该做的是三件事：把这个仅测试使用的类从公共模块主源搬到测试构件（否则它会随 API 构件发布）、给 hive 补一条调用它的契约测试（补上那个精确的覆盖缺口）、把它扩展成同时校验按表形态。 +14. **`ConnectorScanPlanProvider` 上四个 `supportsXxx()`**：它们正是能力声明第二层的正确形态，不动。 + +--- + +## 十七、与 Trino 连接器接口设计的对照 + +对照的意义不是「照抄」，而是分清**哪些差异是合理的本地化取舍，哪些是直译后没接线的缺陷**。 + +### 17.1 合理的本地化（不要改回去） + +| 差异 | 判断 | +|---|---| +| Trino 的分片与表句柄完全不透明，由连接器自己序列化，worker 直接反序列化回连接器自己的类；Doris 必须走 thrift 的按数据源联合体 | **合理**。Trino 的 worker 是 JVM 可以加载插件，Doris 的 BE 是 C++ 且无插件机制。这是根因差异 | +| Trino 的元数据接口是每事务一个，生命周期由接口里的事务方法定义；Doris 是每语句一个 + 语句作用域 | **合理**。Doris 引擎没有「每事务一个元数据对象」的概念，语句是它的自然作用域。缺的只是把契约写清 | +| Trino 没有建表引擎名概念；Doris 有一张引擎名白名单 | **合理**。MySQL 兼容的用户可见遗留语法，不可能整体移除。只该把「外部目录的引擎名」变成连接器声明 | +| Trino 的能力协商主要靠「试着下推，不支持就返回空」；Doris 有 13 个布尔能力位 | **合理**。Doris 的优化器在很多点上需要的是**布尔前置门**（能不能开启 Top-N 延迟物化、能不能进后台自动分析、建表能不能接 ORDER BY 子句），不是「试着下推看连接器接不接」 | +| Trino 只有异步分片源；Doris 以同步分片列表为主 + 流式为可选分支 | **合理**。Doris 的扫描节点需要在计划阶段把分片信息落进 thrift | +| Trino 没有「一个目录服务多种表格式」的模型（它靠多个目录）；Doris 有异构网关 | **合理且必要**。正因如此，「7 个写特性只有 4 个有按表形态」才是真缺口——这不是抄漏了，而是本地化没做完 | +| 两边的元数据接口都是上百个默认方法、一律「默认不支持」 | **一致，是本项目做得好的部分** | + +### 17.2 直译后没接线的真缺陷 + +1. **连接器属性描述符体系**：Trino 里它是活的（直接支撑建表的合法键校验与按目录设置会话属性），Doris 直译了类和两个取得器但**没有对应语法接线**，成了零实现零调用的死面。这是照抄未落地，不是取舍。（详见主题四第 4.5 节） +2. **不透明事务句柄**：Trino 里它是整个接口体系的枢轴，Doris 自己管事务、句柄从不跨接口传递，于是成了零引用的空标记接口，而它的文档给出的存在理由可验证为假。 +3. **「下推后是否需要重算统计」的布尔位**：Trino 有对应机制，Doris 没有，零消费方，三个实现一律传 false。 +4. **投影下推的赋值信息**：Trino 会用它重写计划节点，Doris 引擎只取句柄，连接器被要求构造引擎会丢弃的数据。 +5. **`applyLimit`**：Trino 里是活的协商入口，Doris 有两条 limit 通路而只有另一条接线，且这条的调用时机绕过安全抑制。 +6. **分片形态枚举**：Trino 没有「分片类型」这一层，Doris 自造了封闭枚举、把数据源名字写进公共枚举，还配了一个必须实现却无出口的抽象方法。**这是自造的缺陷**。 +7. **推模型的缓存失效**：Trino 没有这个接口（它的元数据缓存生命周期在连接器内），Doris 自造了推通道，已被拉模型取代且引擎履约不了它的契约。 +8. **能力经字符串表偷运**：Trino 的按表差异走类型化字段，从不用字符串表承载结构化事实。 +9. **在入口接口上做 provider 方法的镜像转发**：Trino 里不存在这种东西——能力永远只在它归属的那个 provider 上。 +10. **函数调用节点的名字字段被三义复用**（真函数名 / 算术运算符号 / 引擎渲染好的整段 Doris 方言 SQL 片段）：Trino 的对应节点持有强类型函数名 + 类型，**从不**偷运 SQL 文本；Trino 接口里根本没有「渲染好的 SQL 片段」这个概念。Doris 这个字段目前只靠一个连接器里的一条正则区分三种形态——**这是本轮发现里最纯正的接口设计缺陷**。建议加一个载荷判别枚举（函数 / 算术运算符 / 已渲染 SQL）。 +11. **`ConnectorType` 是字符串 token 而非一等类型系统**：Trino 的类型是接口一等公民（对象而非名字）。这是设计缺陷，但**迁移成本已不可承受**，只补文档是此刻唯一理性的处置。 +12. **服务发现工厂的类型上界泄漏**：Trino 的插件与连接器工厂是两个独立类型、没有继承约束；Doris 的 provider 因继承插件工厂而带了一个必抛异常的无参构造方法。 + +--- + +## 十八、给下一步的三个具体动作 + +1. **先合第 1、2、3 批**（写规则 + 文档据实 + 零破坏分域）。这三批不改变任何运行时行为，但它们直接解决用户提出的「后续新增连接器时能够清晰地实现接口」——今天一个新连接器作者的主要困难不是接口能力不够，而是**没有任何地方告诉他规则是什么，而文档告诉他的有一部分是错的**。 +2. **然后合第 5 批（删类型白名单）**。这是唯一能真正兑现「新增连接器不需要修改公共模块」的一批；在它合入之前，这个承诺在代码上是假的。 +3. **就第 4.5 节（连接器自声明属性）先做决策**：接线成声明式属性，还是删掉那三个死接口。这条卡着「连接器加一个可调参数是否需要改公共模块」这个问题的最终答案，且它牵动用户可见的配置位置，必须由人拍板，不宜由整治批次顺手带过。 + + +--- + +## 附录 A：全部结论清单（172 条） +

C.2 那份文档需要修正的地方 + +**五处事实错误**： + +1. **「8 个真实连接器没有任何一个调用过契约校验器」——错。** 实测有 4 个连接器的契约测试在调用（iceberg / es / maxcompute / jdbc 各一处）。由此推出的「这些规则今天完全没有被验证」「注释描述了并不存在的机制」两条结论随之作废。真实缺口精确到一点：唯一声明了分区哈希写的 hive 没有调用点，所以那两条不变量缺真实连接器正样本。（本文主题十一与主题十六第 13 条采用的是修正后的版本。） +2. 「7 个连接器实现了分片类型方法」——实测 **8 个**（漏了 trino）。 +3. 「分片类型的两个方法都没有默认实现」——实测只有分片上那个是抽象的，扫描计划提供者上那个有默认值。 +4. 「写侧分区规格存在『空规格＝另一回事』的第三态」——代码与文档里都不存在，是虚构的第三态。该处文档写得很清楚（明确写了「`null`（不是空规格）表示目标表无分区」并给了理由）。 +5. 规模数字若干处偏差：入口接口 34 个方法（非 32）、会话接口 15 个（非 14）、分区信息值对象 6 个构造器（非 8）、公共 API 模块 10149 行（非约 9800）。 + +**三处需要改结论（不是改数字）**： + +1. 推模型的失效接口应**删除**，不是改名——它零连接器调用，且引擎侧履约不了它的分区粒度契约。 +2. 分区空值哨兵**不能下沉**到 hive 连接器：引擎自己的路径解析在用它，非 hive 连接器（paimon）主动把空分区名归一到它，而且引擎侧已经存在第二份同串定义——下沉只会变成三份。 +3. 压缩类型调整方法**不算中立性违规**：它的文档存在的目的恰恰是把 Hadoop 专有事实圈在连接器里、让通用节点保持与连接器无关。那份文档在两个小节里对同一处给了互相打架的定性。 + +### C.3 那份文档独有、经核实成立、应当并入的六条 + +这六条本轮没有覆盖到，实测成立，补记在此： + +1. **`ConnectorScanRange.getFileFormat()` 的默认值是 `"jni"`**（`:67-68`），把「文件格式」与「读取机制」混在一个字段里。5 个连接器覆写它，jdbc / trino / maxcompute 吃默认值。这一条与本项目已知的一个坑直接相关：扫描级的格式类型决定 BE 走 V1 还是 V2 读取器，发错值会把整个连接器永久钉在 V1。 +2. **`supportsCreateDatabase()` 与 `createDatabase()` 必须手工同进同退**（`ConnectorSchemaOps.java:58` / `:63`）：只实现后者会跳过引擎的远端预检，导致「远端已存在但本 FE 缓存没有」时抛远端错误而不是静默成功。四家连接器成对实现。**但那份文档提的修法（删布尔位、靠异常判定）不可行**——那个布尔门的作用正是不给不支持建库的连接器发无谓的远端查询，删掉会让 jdbc / es / trino 每次「若不存在则建库」都多打一次远端。正解是保留布尔位 + 补一条契约测试。 +3. **带快照与不带快照的成对重载堆叠**：读 schema 与取列句柄各有一对，表统计有带快照的重载而列统计没有。 +4. **`buildTableDescriptor` 用内联全限定名写 thrift 返回类型**（`ConnectorTableOps.java:464`）——风格与公共模块其它 5 处 `import` 不一致，本身就是「知道这里不该出现它」的痕迹。（本文主题六已收录这一点。） +5. **「提供者每次新建、无状态」与「要求它释放跨调用的读事务」自相矛盾**：入口接口文档原文写着提供者是每次调用新建且无状态（`Connector.java:75-77`），而扫描计划提供者上却有一个释放读事务的方法（`:540`），hive 只能把状态挂在连接器级的管理器上。这是契约内部的自相矛盾（公共模块已用查询标识作跨调用键把这条缝写进契约），属文档层问题，实现不会踩雷。 +6. **按名字寻址导致异构网关拿不到表注释**：`getTableComment` 用库名 + 表名寻址（`ConnectorTableOps.java:423`），默认返回空串，hive 网关**完全没有覆写**它，而引擎正是用它实现表注释。后果：同一张 Iceberg 表在独立 Iceberg 目录下有注释，挂在 Hive 元存储目录下拿到空串；hive 自身的表注释也恒为空。**这是「按名字寻址无法委派给兄弟连接器」这个设计问题的第一个可观测代价**，值得单独修。 + +### C.4 本轮独有、优先级应排在那份文档全部条目之前的三条 + +那份文档在结尾自陈未覆盖三个包（下推、建表请求、多版本），并判断「这三组主要是值对象，中立性上没有明显问题」。本轮恰好在这三块查出了整份材料里最严重的几条，说明那句判断下得太早： + +1. **三路以上 OR 谓词会丢行**（trino 连接器只读前两个 disjunct）——**全部材料里唯一可能静默少数据的问题**。 +2. **复杂类型字段名被丢弃，引擎静默编造替代名**（trino 连接器构造 STRUCT 时不传字段名）。 +3. **通用扫描节点里仍有 ES 专有分支**——这直接违反「通用接口层禁止出现数据源专有代码」这条既定规则，而且同一个文件里自己写了这条规则、承接钩子也已经存在、ES 连接器还已经实现了那个钩子。 + +### C.5 两份文档的处置建议 + +**都保留。** 那份文档在若干处的事实核对比本文更精确（尤其是接口规模与写特性一节），本文在若干处推翻了它的结论并补出了它明示未查的三个包。建议在那份文档头部加一行指向本文，并按 C.2 列出的五处事实错误与三处结论改动就地修正——**不要用本文覆盖它**，两轮独立结论的并存本身就是可信度证据。 + +--- + +## 附录 D：完备性补检 + +前面 14 个审查单元有一个共同盲区：**它们审的都是「连接器实现的那一侧」**。补检单元把 100 个公共源文件与已确认结论做交叉，逐个读完了 19 个**完全没有被任何结论覆盖**的文件，并把「由引擎实现、连接器消费」的那几个接口当作一类单独审。结果如下。 + +### D.1 读路径存在一个改不掉的硬阻塞（比正文主题四写的更严重） + +正文主题四第 4.1 节（3）已并入这一条的结论：BE 侧的 JNI 分支本该是插件的通用逃生门，实测它**自己也是封闭的**（`be/src/exec/scan/file_scanner.cpp:1081-1174`，6 段按源名的 if-else，无 else、无「按参数给我一个读取器类名」的入口；原生读取链 `:1408-1530` 同样如此）。引擎侧把连接器给的格式串原样透传（`PluginDrivenScanNode.java:1793`），未识别格式在格式类型映射里落到 JNI（`:1972-1973`），于是走到 BE 的 JNI 分支、匹配不上任何源名、读取器为空、在 `:1326-1330` 抛「不支持为该表格式创建读取器」。 + +**结论**：「新增连接器不需要改公共模块」这句话在**读路径**上根本不成立——必须改共享 IDL + BE。这是根因性的（BE 是 C++ 且无插件机制），FE 侧的任何接口设计都消除不了它。文档必须明写这一点，否则第一个树外连接器作者会在跑通 `CREATE CATALOG` 之后才撞上它。 + +### D.2 由引擎实现的接口，默认值全是「静默降级」，而且今天已经有两个包装类漏转发 + +**这是补检发现的最有行动价值的一条。** + +`ConnectorContext` 的 19 个方法里**只有 2 个是抽象的**（取目录名、取目录 id），其余 17 个都有默认实现，而这些默认值的语义是：地址消毒原样返回（`:79-81`）、认证包装**直接跑、不套安全上下文**（`:98-100`）、失效通知返回空操作（`:109-111`）、**取文件系统返回 `null`**（`:391-393`）、取存储属性/BE 存储属性/broker 地址返回空、空目录清理什么都不做（`:412-414`）。 + +对比之下，同样由引擎实现的 `ConnectorValidationContext` 是 **6 个方法全抽象**，而连接器侧要实现的 `ConnectorProvider` 是 2 抽象 + 5 默认（方向正确）。**同一类接口三套不同政策，两个模块里没有任何成文规则。** + +**活证据（不是假设）**：iceberg 与 paimon 各有一个把线程上下文类加载器钉到插件加载器上的包装类，它们逐方法转发 `ConnectorContext`—— + +- `fe-connector-iceberg/.../TcclPinningConnectorContext.java:99-208` 只转发 **18/19**，漏了取文件系统； +- `fe-connector-paimon/.../TcclPinningConnectorContext.java:77-177` 只转发 **17/19**，漏了取文件系统与批量地址归一器。 + +漏转发**不会有编译错误**，包装类会返回接口默认值。**注意定性**：实测 iceberg 与 paimon **今天都还没有任何一处调用引擎文件系统**（hive 有 6 处直接调用、并经内部辅助方法扩散到约 19 处）。所以这是**潜伏缺陷，不是当前可观测的错误**——这两个连接器一旦开始用它，拿到的会是 `null` 而不是引擎文件系统。paimon 漏转发的批量地址归一器属于另一种性质：行为仍正确，只是退回逐次归一，是**静默的性能回退**。更要紧的是机理：**以后每往 `ConnectorContext` 加一个带默认实现的方法，这两个包装类都会静默丢掉那次类加载器钉桩**——正是本项目已经踩过并记录过的类加载器分裂事故类型，而编译器不会提示。 + +**建议**：把引擎必须履约的方法改成抽象（至少地址消毒、认证包装、取文件系统这三类安全与资源方法），或者让两个钉桩包装类改为继承公共模块提供的一个转发基类——一处补全，包装类不再逐个手抄。 + +### D.3 会话接口同病，且有一个默认值会静默关掉刚做完的性能优化 + +`ConnectorSession.getStatementScope()` 的默认值是「不做任何记忆」（`:142`）。任何没有覆写它的会话实现都会**静默关闭全部按语句的记忆化**——本项目刚落地的按语句去重优化会全部失效，且没有任何日志。 + +`getSessionId()` 默认回退到查询 id（`:42`），而它自己的文档说存在理由就是「跨查询稳定以复用一次认证的会话」——默认值恰好破坏了这个目的。`getSessionProperties()` 默认返回空表，于是所有由会话变量驱动的连接器行为静默走死默认。 + +成本侧证据：全仓 19 个会话实现，其中 18 个是测试替身，每个都要手写 8 个抽象方法。而抽象与默认的划分没有原则可循：取区域设置是抽象的（几乎无人真正需要），取语句作用域（正确性与性能关键）反而是默认的。 + +### D.4 新增一个只读连接器的真实最小成本（量化「可发现性」缺陷） + +按编译器强制的抽象方法实测，一个新连接器的**最小实现集**是： + +- 服务发现侧：取类型名、创建连接器（其余有默认实现；另继承一个语义上不存在的无参创建方法）； +- 入口接口：**只有 1 个**（取元数据对象）； +- 元数据接口及其 6 个子接口：**抽象方法 0 个**。 + +也就是说**编译能通过，但一行也不工作**。要真正可用，作者必须「自己发现」该覆写哪些——取表句柄、取表 schema（默认抛「未实现」）、取列句柄、列库名、列表名、判库存在。**这是「可发现性」缺陷的量化证据：46 个默认方法里没有任何机器可读的「最小实现集」标记，只能靠抄别的连接器。** 这也是正文建议第 3 批（按域拆父接口 + 每域写清最少实现集）真正要解决的问题。 + +扫描侧最小集是：一个分片生成方法（唯一的抽象方法）+ 一个分片实现，而后者强制实现两个方法，其中一个（分片类型）**已被证明是死表面**。 + +### D.5 两个「直觉上以为要改、实测不用改」的点 + +这两条值得明确写下来，否则会被当成漏检： + +1. **新连接器不需要任何持久化注册。** 所有插件目录/库/表共用同一套通用类的 Gson 子类型；`GsonUtils.java:362-506` 里全是「老类型 → 通用插件类」的**兼容映射**，不是新增点。新连接器零 Gson 改动、零镜像兼容负担。 +2. **标量类型映射不是封闭分支。** 引擎侧的类型反向构造在默认分支直接按名字创建 Doris 标量类型（`ConnectorColumnConverter.java:322-328`），所以新连接器可以直接用任意 Doris 标量类型名而**无需改引擎**。（先前只提到「拼错会静默退化为不支持类型」，这一半是好消息，应一并记下。） + +### D.6 补检出的其余问题 + +| # | 问题 | 位置 | 严重度 | +|---|---|---|---| +| 1 | **标识符映射只有「远端名 → 本地名」单方向**，反向映射事实上由引擎自己在缓存对象上承担，而 jdbc 连接器内部其实两个方向都实现了。这条关键分工既不在文档里，也不对称——任何需要「按本地名反查远端名」的新能力都会再在引擎侧造一次轮子 | `ConnectorIdentifierOps.java:37/49/63` | 低 | +| 2 | **`Serializable` 是零执行的假契约，且已被实现规避/违反**：四个公共类型声明了它，每个实现都被迫写序列化版本号；但引擎全树没有任何序列化这些类型的路径。而且 trino 的表句柄把真身字段声明为 `transient`（反序列化后必然不可用），hive 的表句柄持有一个**不可序列化**的类型（真序列化会抛异常）。建议删掉这个声明，或写清「引擎从不序列化，声明仅为将来预留」 | `handle/ConnectorTableHandle.java:25` 等 4 处 | 低 | +| 3 | **句柄家族的身份契约不对称**：列句柄用重声明 `equals`/`hashCode` 强制身份语义，表句柄什么都不要求——尽管表句柄会进语句作用域的键、跨 provider 传递、参与 EXPLAIN。另外具名列句柄是非 final 类而 `equals` 用 `instanceof` 判定，子类加字段后会与父类互等，破坏它所在接口强制的身份契约；透传查询句柄的构造器不校验查询串非空而 `toString()` 直接取子串（空值会抛空指针） | `handle/` 四个文件 | 低 | +| 4 | **库元数据对象里唯一被消费的是属性表里的位置字段，名字字段零消费**（调用方本来就传入库名）。这是第 4 处「结构化信息塞进属性表」。附带：子接口的默认实现返回空属性表，把「本数据源没有位置概念」和「位置为空」塌成同一态 | `ConnectorDatabaseMetadata.java:33/46-48`、`ConnectorSchemaOps.java:47-50` | 低 | +| 5 | **复杂类型的元数（arity）契约缺失**：数组需 1 个子类型、映射需 2 个、结构体 n 个，构造器不做任何校验；引擎对空子类型列表**静默产出 `ARRAY` / `MAP`**（无告警）。四组平行列表同样「越界即未设置」、无长度校验。（正文主题十一第 11.1 节（2）只覆盖了结构体字段名这一半） | `ConnectorType.java` 构造器、`ConnectorColumnConverter.java:242-249` | 低 | +| 6 | **表格式字符串的第三份定义在引擎侧**：一个 10 值的按源名枚举只服务遗留路径，插件路径根本不经过它；但 iceberg 连接器的文档反过来把这个**引擎私有枚举**当作自己返回值的权威词表。于是同一词表有三份定义（引擎枚举 / BE 的 if 链 / 各连接器字面量），公共模块一份都不持有 | `fe-core/.../scan/TableFormatType.java:20-30`、`IcebergScanRange.java:207-208` | 低 | +| 7 | **区间谓词未声明边界是否含端点**（SQL 的 BETWEEN 含端点）；**分片源继承的关闭方法未说明谁负责吞异常**。都是一句文档的事 |

直通接口做成通用路径透传**（`executeRestRequest(path, body)`），不做成 `getMapping` / `search` 两个具名方法。理由：具名版会把两个 ES 词汇的动词写进本该中立的公共模块；端点侧的路径拼接与安全面单独立项处理。 +- **19 号｜那两个 HTTP 端点的既有安全面记录并单独立项**（表名不校验直接拼进 URL、无目录级权限检查、口令检查只在某全局开关打开时才做），本批不动。 + +--- + +## ⚠ 必须先定的四件事 + +1. **含隐式类型转换的谓词下推默认值**（08 号）：`supportsCastPredicatePushdown` 目前默认 `true`，而它承诺的「引擎会先剥掉类型转换」只对残余谓词那条路径成立。改成默认 `false`（安全侧）等于跨六个连接器的行为改动，会在残余谓词路径上少推一些谓词。三个选项见 08 号文档 5.1。 +2. **连接器自声明属性：接线还是删除**（24 号）：影响 FE 配置项的用户可见位置，涉及兼容承诺。文档推荐删除并把入口形状记进设计文档，理由是接线也解决不了真实卡点。 +3. **建表能力下沉后有三类组合的报错文案会变**（18 号）：改前改后都是拒绝，只是拒绝点提前。要么接受文案变化，要么在下沉时保留原文案。**另外 18 号还纠正了一个会误导施工的事实：仓库里根本不存在分桶子句的正向端到端护栏**，这个任务必须自己补一条。 +4. ~~**插件与内建目录类型的路由优先级**（15 号）~~ **已拍板并落地，见上面第 6 条。** + +## 其余条目（按任务编号） + +### 01　修复 trino 连接器对三路以上 OR 谓词只取前两支导致的丢行 + +1) 是否接受把 `ConnectorAnd` 的同类改动（浅包裹 → 真拷贝 + 至少两个校验）排除在本次提交之外？文档按「排除」写，理由是它今天所有生产者都已守住 ≥2、无实际风险，混进来会稀释一个正确性修复的变更意图。若希望一次改完，把 5.3 的第一条移进 5.2 即可。2) 新加的构造器校验是硬抛 IllegalArgumentException（单分支 OR 视为调用方逻辑错误，要求当场暴露）。如果更偏保守（担心某条冷路径在生产上因此抛错），可改成「降级为返回唯一分支 + WARN 日志」，但那会让契约重新变成软约束——需要拍板取哪一种。3) 端到端回归是否要求本任务同步补进 external_table_p0/trino_connector 的现有用例（需要 docker 环境实跑），还是允许只交单元测试、e2e 与其它三条缺陷修复一起统一补。 + +### 02　修复 paimon 连接器把「空值安全等于」下推成 IS NULL 导致的丢行 + +1）空值字面量那一半要不要一起做？最小正确性修复只需「非空字面量 → equal」；额外把 `c <=> NULL` 下推成 IS NULL 是新增裁剪能力（与 iceberg 对齐、语义安全，因 isNull 只依赖空值计数统计与类型无关）。文档给了推荐方案（两半都做）与最小方案（只做非空那半），需用户拍板取哪个。2）要不要补 paimon 端到端回归用例？补的话用例里必须 `set disable_nereids_rules='NULL_SAFE_EQUAL_TO_EQUAL'` 才压得到连接器路径，需要 docker 环境；文档现列为可选、不阻塞合并。3）本文档刻意不改 ConnectorComparison 的契约文字（留给「下推表达式契约补全」任务），如果用户希望两件事一次提交完成，需要明确合并顺序以免同一行冲突。 + +### 03　修复 paimon 连接器把含单字符通配符或转义的 LIKE 收窄成前缀匹配 + +1) es 那处 REGEXP 锚定语义不一致是否与本任务同批修？文档已按「由排期决定、本任务不做」处理，需用户拍板。2) 同一个文件里的空值安全比较缺陷（`列 <=> 5` 被下推成 IS NULL）是另一份任务，是否与本任务并到同一次端到端回归里跑？文档给了建议但未替用户决定。3) 修复后 `_`/转义/中间 `%` 三类模式串不再裁剪文件，会多读数据——这是「快但错」换「慢但对」，方向上不认为有争议，但若有对 LIKE 性能敏感的场景需用户知晓。 + +### 04　修复 trino 连接器丢弃复杂类型字段名导致引擎编造 col0 / col1 + +1) 匿名 ROW 字段的命名：文档选择 `col` + 下标（与引擎兜底及其它四个连接器一致），有意不复刻迁移前「所有匿名字段都叫 col」的重名行为——这是唯一一处刻意的行为偏离，若你要求严格 legacy parity 请拍板改回。2) 新校验对「非复杂类型标签带了子类型」不做检查（typeName 是无词表裸字符串，不能反向断言），是否接受这个收窄。3) fe-core 侧 ConnectorColumnConverter 的三处静默降级分支（col+下标、ARRAY、MAP）文档建议零改动保留为防御（fe-core 只出不进 + 改抛会把单列退化升级为整表加载失败），若你希望它们也 fail loud 需单独立项。4) 是否要求本任务必须补 trino 的 STRUCT 端到端用例（现状零覆盖），还是接受仅单元测试验收。 + +### 05　修复 hudi 在「最后修改时间」字段里填时刻串导致查询缓存永久失效 + +1) 时区处理要不要按我推荐的「从表配置 getTimelineTimezone() 读」来做（多两个方法、零额外远程调用、消除显式 UTC 表的小时级偏差），还是接受一行的 HoodieInstantTimeGenerator.parseDateFromInstantTime（更简单，但按 FE 全局时区解析）。我在文档里已选前者，若你偏好极简可以改。2) instant 解析失败时的策略：我选了 log warn + 返回 0（不炸查询热路径），这与仓库里同一条路径上 requestedTimeToInstant 的 Long.parseLong 「fail-loud」风格不完全一致，是否接受这个不一致。3) 端到端用例放 p2（hudi 环境在 p2）意味着它不进 p0 常规回归，只在跑 hudi 外部环境时验证；是否需要额外在 p0 加一条不依赖 hudi 环境的替代守卫（目前靠单测的量级断言承担）。 + +### 06　补齐两个连接器对引擎上下文的转发缺口，并根治「加一个方法就漏一次类加载器钉桩」的机理 + +1) 转发基类叫 ForwardingConnectorContext 并放在 fe-connector-spi（org.apache.doris.connector.spi），等于给公共模块新增一个公共类。这条工作线的目标是「新增连接器不必改公共模块」，新增基类方向一致，但仍是公共表面 +1，请确认接受；若不接受，退路是只手工补齐两处漏转发（不根治机理，以后每加方法仍会漏）。 +2) 基类只保证「不丢转发」，不保证「不丢钉桩」——将来新增的方法若会进入插件代码，仍需钉桩子类显式覆写。文档把这条残留风险写进基类注释与单测失败提示。是否接受这个边界，还是希望更强的做法（例如默认全部方法都钉桩、只对明确不需要的方法 opt-out）？后者会改变现有行为并带来无谓开销，我不推荐。 +3) 任务 14（删除推模型失效接口）也要改这两个包装类，文档已建议 06 先做、14 后做。若排期上想反过来，需要在 14 里重做一次同样的迁移。 + +### 07　把公共模块的设计规则写下来（两个模块各一份包级说明） + +1) 包级说明正文用英文还是中文：文档已按仓库既有 javadoc 惯例（fe-connector-cache/package-info.java、全部接口 javadoc 均为英文，且这条线最终要进上游 apache/doris）定为英文，中文只出现在本施工说明书里。若用户希望包级说明写中文，需要在动手前拍板。2) fe-connector-api/pom.xml:35-38「Consumer-facing API」的修正不在种子明确列出的范围内（种子只点了 spi/pom.xml:38 的 ConnectorTypeMapper），我按「规则四要说清模块名与内容倒置」把它一并列入改动清单（一行描述、零风险）；如希望严格限定范围，可从清单里去掉。3) 规则二的异常四分类是否要落成真实的异常子类（如 DorisConnectorUserException 等），本任务按「只写规则不加类」处理（加子类会牵动全部连接器的 throw 点与引擎 catch，属独立任务）；若用户希望本轮就建子类层次，需另立任务并重排依赖。 + +### 08　修正与实现矛盾的接口文档（一批） + +1) `supportsCastPredicatePushdown` 的默认值怎么办（必须拍板，文档 5.1 给了三选项）：A 默认翻 false（对齐 opt-in 纪律，但等于跨 iceberg/hive/hudi/es/trino/hms 六个连接器的行为改动，会在残余谓词路径少推谓词）；B 本批只改文档、默认值不动、翻转另开一项配端到端回归（我推荐 B）；C 引擎在拆壳处打标记让连接器能自查（要在公共接口加表达能力，远期）。 +2) 三处与「删掉没有调用方的接口面」任务重叠的符号（listPartitionValues、ConnectorScanRangeType 一族、getCurrentEventId）：确认按「删除任务处理、本任务不改文档」执行？若你决定保留其中任何一个，请告知，我在 5.2 已给出对应的文档改法。 +3) 六处裸工单号 `#65329` 是否要清（改成行为描述 / 写全 apache/doris#65329 / 原样保留）？它是上游公开编号，不属于内部符号泄漏，故列为可选项。 +4) 可选的 hive 契约测试正样本（补一行 validate 调用）要不要做？如果 hive 连接器在无元存储的单测环境里构造不出写计划提供者，我的处置是不硬凑、只在 javadoc 里记下缺口——确认可接受？ + +### 09　补全下推表达式的契约（逐算子语义 + 不可精确翻译必须放弃下推） + +**已完成（2026-07-25）。** 1) 与 2) 已拍板见上面第 10、12 条；3) 按「如实记录不统一」执行。原文保留以备回溯： +1) 可选工具方法要不要做：文档给的是「只加一个 ConnectorLikePatterns.exactPrefix，EQ_FOR_NULL 不加工具方法」的最小方案；若希望零新增 API（纯文档任务），可整块摘掉，其余不受影响。2) 与任务 07、08 的文档分工需拍板确认：本文约定 pushdown 包内文档 + ConnectorScanPlanProvider/ScanNodePropertiesResult 上残差协议相关那几行归 09，其余陈旧文档归 08；若 08 的清单已包含这几处，请以先落地者为准并划掉重复项。3) 列名大小写规则目前各连接器自行决定（paimon 强制小写、jdbc 走映射表），本任务只如实记录不统一；要不要统一是行为决策，需另开任务并拍板。 + +### 10　把 ConnectorTableOps 按域拆成父接口，并为每域写清最少实现集 + +1) 域的个数：要不要把系统表三方法（listSupportedSysTables / getSysTableHandle / isPartitionValuesSysTable）从「表基础」里再拆出第 7 个域？拆了「表基础」从 14 降到 11、最少实现集更干净；不拆则与调研建议的 6 域一致。我按 6 域写。2) executeStmt / getColumnsFromQuery 暫留聚合接口是否可接受？替代方案是本任务就把它们摘成可选接口，但那会牵动 jdbc 连接器，本任务就不再是零破坏。3) 「方法集合冻结」测试的基线文件在后续删死接口批次里必然要改（那是故意的减速带），是否接受这个维护成本？若不接受，可退化为只断言方法数量与「每个域接口的方法名集合」两条较松的断言。4) 标记注解取名 ConnectorMustImplement（含 when() 说明触发前提）是否合意，还是更偏好统一的 javadoc 标签而完全不引入新类型？ + +### 11　删除第一批死接口面（公共模块内部，不动连接器生产代码） + +**已完成（2026-07-25，5 个提交）。** 下面这条已拍板为「删除」，保留原文以备回溯：ConnectorCreateTableRequest.isExternal 的处置——选项 A 直接删（建议）／选项 B 保留但必须同时补类文档说明「external 在连接器语境下的确切含义」并让至少一个连接器真正读它改变行为（如 hive 决定写 EXTERNAL_TABLE 还是 MANAGED_TABLE）／选项 C 维持零消费零文档（不允许）。 +另外一提：另一条同性质判断题 getPrimaryKeys（含 ConnectorTableSchema.PRIMARY_KEYS_KEY）要改 paimon 生产代码，不在本批，留给「需连带改连接器」那批一并拍板。 + +### 12　删除第二批死接口面（需要连带修改连接器） + +**已完成（2026-07-25）。** 四条全部拍板：1) 见上面第 13 条；2) 见第 11 条；3) 保留 jdbc 客户端层方法；4) 见第 9 条（删）。原文保留以备回溯： +1) hive 的 properties 死字段怎么收：推荐「删字段+赋值、保留全部构造签名（最宽构造器留一个未用形参）」，代价是留一个未用形参；若评审更在意形参整洁，则要动最宽构造器签名及其调用点（构造点共 31 处，需另做一笔独立改动）。 +2) hudi 的 partition_values() 新鲜度：今天走缓存，可能落后一个 TTL。要不要改成绕过缓存取最新？本任务不改，只把注释与测试改成据实描述。 +3) jdbc 连接器内部三处 getPrimaryKeys（client 层）删掉 SPI 覆写后暂无调用者：保留（推荐）还是同批清理？清理会牵动 MySQL 的 KEY_SEQ 重排与 OceanBase 委派，属连接器内部事务。 +4) 调研报告 7.4 节把 getPrimaryKeys 标为「判断题不是事实题」：本文按「删」写。若最终决定保留主键接口，则必须同时补契约文档并让至少一个连接器真正消费它，不允许维持零消费+零文档 —— 这一点需要在动手前确认口径。 + +### 13　删除分片类型枚举族（本轮最有价值的一条删除） + +**已完成（2026-07-25）。** 两条排除项均按「不做」拍板，见上面第 14 条。原文保留以备回溯： +1) getProperties() 是否也降为带默认实现（返回空表）——文档给出的建议是「本任务不做」，理由是收益仅 5 处、代价是 jdbc 那条唯一走默认 populateRangeParams 的链路失去编译期强制；如果你希望把 ConnectorScanRange 做成「零必须实现方法」的接口，这一项需要你拍板，并应作为独立提交。2) 是否顺带清掉同样落在 jdbc_params 里、BE 也不读的 connector_file_format 键（连带 ConnectorScanRange.getFileFormat() 这条表面）——我按「不扩大范围」处理成排除项，因为它牵动扫描级格式类型这条已知风险线；若你希望一次删干净，可把它并入本任务或单开一条。 + +### 14　删除推模型的缓存失效接口，让「失效」只剩一个方向 + +**已完成（2026-07-25）。** 1) 06 号先落地，本轮照删（转发已收到公共基类，删除点是那一处而非两个连接器）；2) 见上面第 15 条；3) 旧计划文档的作废说明随本轮文档提交补。原文保留以备回溯： +1) 顺序拍板：本任务与编号 06（补齐上下文包装类转发缺口）是「先删后补」还是合成一个提交？文档默认建议先删本任务。 +2) IcebergProcedureOpsTest 里 7 处 ctx.invalidatedTables 断言，文档主张删掉（删接口后其失败条件在类型层面不可能出现，留着就是永不会红的测试），设计意图保留在类注释里——若你更希望保留某种形式的守护断言，需要另行指定形式。 +3) 早期计划文档（00-connector-migration-master-plan.md、01-spi-extensions-rfc.md、decisions-log.md 的 D-004）里仍写「HMS 事件管线通过这个接口回调」，文档建议补一句作废说明而不改写历史进度记录——是否照此处理由你确认。 + +### 15　删除目录类型白名单，让注册了插件的连接器真的能被路由到 + +1) 路由顺序：文档采纳「插件优先于引擎内建类型」（保持现有七个类型行为逐字不变），代价是第三方插件可以遮蔽 `doris`/`test`/`lakesoul` 这三个内建类型名。若你更希望内建类型不可被遮蔽，需要改成「内建优先」并在 getType() 契约里把这三个名字列为保留字——请拍板。2) 插件目录批次撞名的处置：文档选「跳过后来者 + LOG.error」以保住 loadPlugins 既有的「部分成功、不阻塞 FE 启动」契约；类路径批次选「抛 IllegalStateException」。若你认为撞名严重到应当一律阻止 FE 启动（宁可起不来也不要不确定的胜者），需要改口径。3) 类型冲突检测建议抽一个包内可见的登记方法以便直测——这是为可测性引入的一个小接缝，若你不接受在 fe-core 增加这个接缝，则该条只能靠伪造 META-INF/services 来测（不推荐）。4) 建目录报错文案里要不要列出「当前已注册类型」清单：这会把已安装插件列表暴露给任何能执行 CREATE CATALOG 的用户，可诊断性与信息暴露的取舍请确认。 + +### 16　把引擎里三处按数据源名判定的软阻塞分支改成中立声明 + +1) `supportsFileCache()` 这个方法名要不要换（候选：`participatesInFileCache()` / `readsWithNativeFileReader()`）——语义是「数据由 BE 原生文件读取器读取、BE 文件缓存对它有效」，用 supportsXxx 前缀是为了对齐既有 supportsBatchScan / supportsTableSample 的约定，但名字本身不如后两个候选自解释。2) paimon 的文件缓存声明：今天白名单里有 `paimon`，但 paimon 的部分表走 JNI 读取（`supportsTableSample` 的 javadoc 明确说 Paimon JNI ranges 长度为 -1）。本文按「零行为差」要求 PaimonScanPlanProvider 声明 true 以保持现状；如果 owner 认为「JNI 读取不该做准入判定」，那这次迁移就顺带修一个既存的误覆盖，需要拍板是保现状还是改语义。3) 四处是否拆成 4 个独立提交（本文建议拆），以及第四处（删剖析常量）要不要单独走一次评审——它会改变所有查询的剖析输出行。 + +### 17　把按表能力从字符串升级为类型化集合，并删掉写特性的镜像方法 + +1. 写特性镜像方法的删除范围：文档按 11 个（含 2 个 supportedWriteOperations）来写，调研报告口径是 9 个。若坚持只删 9 个，入口接口上会残留同一种镜像，需要用户确认取哪个口径。 +2. 让 iceberg-on-HMS 表继承 SUPPORTS_SHOW_CREATE_DDL / SUPPORTS_VIEW / SUPPORTS_METADATA_PRELOAD 是不是想要的改进？文档把它明确排除在本任务之外（列进「不要顺手做」，理由是真实行为变化需独立评审 + 异构目录端到端回归）。若用户认为这本身就是要兑现的能力，应作为独立任务排期。 +3. 「fe-core 只出不进」的判定：文档在 PluginDrivenExternalCatalog 上新增一个通用访问器 hasConnectorCapability，用来替掉 4 个类里重复的样板判断（整体净删行、非数据源相关代码）。若用户认为这仍属「往 fe-core 加东西」，可退化为各调用点原地保留直读，只做类型化那部分。 + +### 18　把建表能力从引擎白名单下沉为连接器声明（高风险，需端到端兜底） + +1) `analyzeEngine` 的判据从「引擎名」换成「目标目录的能力位」后，有三类组合的**报错文案会变**（改前改后都是拒绝，只是拒绝点提前）：内部目录写 `ENGINE=hive` 且带 `PARTITION BY`；jdbc 目录写 `ENGINE=hive` 且带 `PARTITION BY`；非插件的 `doris`/`test` 目录建表。文档给的方案是「实测确认没有用例依赖旧文案就接受这三处文案变化」，若您要求**绝对零文案变化**，则需要在非插件目录场景保留一份封闭的旧引擎名清单（更丑但零变化）——请拍板选哪种。 +2) 新增能力位命名建议为 `SUPPORTS_CREATE_TABLE_PARTITION_BY` / `SUPPORTS_CREATE_TABLE_DISTRIBUTED_BY`（与既有 `SUPPORTS_SORT_ORDER` 同族、都是建表子句门）；如果您更偏好与既有短命名一致的 `SUPPORTS_PARTITION_CLAUSE` 之类，需在动手前定名，之后改名要动 4 个连接器。 +3) 建表引擎名声明放在 `Connector`（实例级，需要不强制初始化的读法）还是放在 `ConnectorProvider`（类型级，天然不需要初始化）？文档推荐 `Connector`，理由是与既有能力位读法同构、且同类不强制初始化的读法已有两处先例；若您希望彻底避开「分析期触碰目录初始化」，可改放 provider，但 fe-core 需要新增一条按类型查 provider 的通路。 + +### 19　把 Elasticsearch 专有的逃生门与通用扫描节点里的 ES 分支归位 + +一个：EXPLAIN 侧缺少 `limit <= batch_size` 判据，会让 batch_size 较小时用户看到一个并未真正生效的 `ES terminate_after`。文档默认逐字保留这个既有不一致（验收基线=EXPLAIN 文本不变），是否允许在搬迁的同一轮里把连接器侧 EXPLAIN 判据补齐成与实际下推一致（代价是 batch_size 小于 LIMIT 时 EXPLAIN 输出会变；现有 p2 用例 limit 5/3 远小于默认 batch_size，不会变红）？已写入第七节。 + +### 20　分区空值哨兵的中立化命名与归一方法下沉 + +1) 中立常量叫什么：文档草案用 NULL_PARTITION_NAME（因为原来占着 NULL_PARTITION_VALUE 名字的 "\\N" 会随方法一起下沉到 hudi，名字腾出来了，不会混淆）。备选 DEFAULT_PARTITION_NAME。请拍板一个名字，否则实施时会反复改 import。 +2) 是否真的要保留 @Deprecated 旧名别名一轮：本仓库内所有引用都会在本任务里一次改完，别名只对「仓库之外按旧名编译的第三方连接器」有意义。如果 fe-connector-api 还没作为公开 API 发布过，可以直接删旧名、少一个过时符号；发布过就按文档保留一轮。 +3) hudi 的空值渲染 "\\N" 与 hive/paimon 的空串是否要统一（BE 在空值位为 true 时理论上忽略该字符串）：文档明确列为「不要顺手做」，若要统一需单独立项并配端到端验证。请确认这个划界。 + +### 21　把扫描节点属性表的键契约集中到公共模块 + +1) `hive.text.` 这个源专属前缀名：本文按「符号名中立化（TEXT_PROPERTY_PREFIX）、字面量保持历史值不变」处理，把真正改值（→ `text.`）排除在外。若您认为「通用层不出现源专属符号」要做彻底、连字面量一起改，请拍板——那需要引擎与 hive 同步改并配 hive 文本/CSV/JSON 端到端回归，风险从「结构调整」升为「有行为风险的改名」。2) 删除 `FileQueryScanNode.getSerializedTable()` 与其 :472 调用（fe-core 纯减 3 行）是否纳入本任务：纳入则树内无残余死钩子，不纳入则 fe-core 留两处死代码。文档按「纳入」写，若您偏好更小改面可拆出。3) 常量类的类名：文中用 `ScanNodePropertyKeys`；若您希望与既有命名（如 `ConnectorPartitionValues`）对齐成 `ConnectorScanNodeProperties`，请指定，动手前改名成本为零。 + +### 22　把分布式过程的结果列定义交还连接器 + +1) 汇总放在哪一侧：本文按「引擎对连接器给出的每组数字做直和后交出四个总数」定稿（理由：改动最小，求和三行本来就在驱动器 :178-180；且统计对象字段与 ConnectorRewriteGroup getter 同名，映射一目了然）。另一个可选形态是把 List 连同新增文件数一起交给连接器、由连接器自行聚合（好处是连接器可选非求和的聚合方式，坏处是把编排对象塞进结果 API）。若用户偏好后者，5.1/5.2 需相应调整。 +2) 新增类与方法的命名是否照批：ConnectorRewriteStatistics / ConnectorProcedureOps#buildRewriteResult。命名刻意避开数据源词，但「rewrite」是否算中立词（本文按「合并重写操作模型的中立词」处理，并在 5.3 明确不重命名既有 ConnectorRewriteDriver / planRewrite / RewriteCapableTransaction）需确认。 +3) 是否顺手给端到端用例补一条列名断言（6.3 可选加强）。补了以后列名从此有端到端护栏，但会让本任务多碰一个 groovy 文件；本文默认不补，等用户拍板。 +4) IcebergRewriteDataFilesAction 是否要同时覆写 getResultSchema()（今天不可达，纯为与八个单次调用兄弟保持自描述一致）。本文建议覆写，属可去掉的 3 行。 + +### 23　把引擎上下文里的存储服务收成独立服务对象（高危） + +1) 引擎侧实现方式：文档推荐让 DefaultConnectorContext 同时实现 ConnectorContext 与 ConnectorStorageContext、getStorageContext() 返回 this（零逻辑搬迁、fe-core 只加约 6 行、6 个 fe-core 单测零改动）。如果用户认为「独立服务对象就该有独立实现类」，需要接受把 300 多行含锁的文件系统缓存与 close() 生命周期搬进新类的额外风险——请拍板取哪一种。 +2) 改名后的方法名：文档定为 sanitizeOutboundUrl（调研报告备选 sanitizeRemoteUrl / validateOutboundEndpoint）。若用户偏好其中另一个，改一处即可。 +3) CURRENT_API_VERSION 是否递增（见 unverified 第 5 条）。 +4) 本任务与任务 14 的先后：两者都改转发基类但互不冲突，文档只要求「不要合在同一个 commit」，未指定先后；如需固定顺序请指示。 + +### 24　待拍板：连接器自声明属性——接线还是删除 + +1) **主决策**：选项一（接线成声明式属性）还是选项二（删掉三个死接口并把入口形状写进设计文档）。文档给出的推荐是选项二，理由三条：该机制即使接线也不解决真实卡点（值住在 fe.conf、无按会话覆盖语法）；它现在挂错位置，接线等于重做设计，留着不省事；它挡住的唯一真缺陷（目录属性拼错键静默失效）有成本低得多的现成入口 ConnectorProvider.validateProperties。 +2) 若拍选项一，是否接受我建议的拆分：本次只做「目录级描述符 + 未知键默认只告警」，把 7 个 fe.conf 键搬迁与「SET SESSION 目录.属性」语法各自单独立项。 +3) 与 11 号任务的去重由谁承担：本文选项二与 11 号任务改动清单第 1 项是同一次删除，需要指定在哪个任务里落地，另一个标注为「已由对方完成」。 +4) 两个已记录但本文明确不做的独立小项，是否要各自立任务：把 max_compute_write_max_block_count 从会话通道搬回环境通道（它是 fe.conf 字段却走了会话属性通道，与 ConnectorSession.getSessionProperties 的 javadoc 冲突）；以及给目录属性加「未知键告警」（无论主决策选哪条都可独立做）。 + +### 25　修正同日另一份评审文档里的事实错误与结论 + +1) 那份文档里被推翻的条目，是「就地改写成修正后的事实」还是「保留原文 + 追加一行『经交叉核对推翻』」？我按前者写（更省读者力气），但对第 589-591 行那种纯转述条目给了删除/留说明两种选项，需要拍板一种以保持全文一致。2) 修正标记用什么字样：我建议统一后缀「（交叉核对修正）」，如果你希望文档看起来干净不留痕，可以改成只在头部说明「本文已按交叉核对结果修订，逐条见任务空间报告附录 C」。3) hive 的契约测试调用点要不要顺带在这一轮补上（会引入 Java 改动、需要全反应堆含测试源 test-compile 验收）？我按「不顺手做」处理，留给代码任务。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/01-fix-trino-or-predicate-row-loss.md

`convertAnd`（`:102-112`）是**遍历全部** `getConjuncts()` 的，只有 OR 这一支是取下标。 + +### 转换结果会真的落到数据源上 + +转换出的 `TupleDomain` 有两个消费点，两处都会把它交给 Trino 自己的连接器做实际过滤： + +| 位置 | 用途 | +| --- | --- | +|

+`TrinoConnectorDorisMetadata.java:292-296` 有一段注释说明它会把原始表达式作为「剩余谓词」回传，让 BE 再算一遍： + +```java +// Trino tracks the remaining filter as a TupleDomain, not as a Doris ConnectorExpression. +// Returning the original expression keeps BE-side re-evaluation, matching the legacy +// fe-core scan-node behavior. +``` + +但 BE 的重算只能**再筛掉**行，不可能把源端根本没返回的行补回来。所以这层兜底对本缺陷完全无效。 + +## 三、为什么这是个问题 + +1. **这是正确性缺陷，而且是静默的。** 用户看不到任何报错或告警，只是结果行数变少。这类问题往往要等到与其它系统对数才被发现。 +2. **实现与公共接口的契约不符。** 接口说自己是 N 元，实现只处理 2 元。八个连接器里只有 trino 这一家是取下标的——`getDisjuncts()` 的全部其它消费者（paimon `PaimonPredicateConverter.java:134`、es `EsQueryDslBuilder.java:267`、maxcompute `MaxComputePredicateConverter.java:152`、iceberg `IcebergPredicateConverter.java:215` 与 `:633`）都在遍历整个列表。 +3. **公共类没有把这个约束变成可执行的校验。** `ConnectorOr` 的文档写了「两个或更多」，构造器却只做非空判断；而且它只用 `Collections.unmodifiableList` 包了调用方传进来的列表**视图**（调用方之后改自己的列表，节点内容就会跟着变），而同一个包里的 `ConnectorIn`（`ConnectorIn.java:40-41`）是先 `new ArrayList<>(...)` 真拷贝再包不可变的。同包两种写法不一致。 + +### 归责：是本次迁移引入的，不是上游既有行为 + +必须写清，因为处理方式不同： + +- **旧实现是对的。** 迁移前 fe-core 的 `TrinoConnectorPredicateConverter`（`git show master:fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/source/TrinoConnectorPredicateConverter.java`，OR 分支在 `:112-115`）也是读 `getChild(0)` / `getChild(1)` 两个孩子，但它的输入是老 Expr 抽象树里的 `CompoundPredicate`——那个类的构造器只接受两个操作数（`git show master:fe/fe-catalog/src/main/java/org/apache/doris/analysis/CompoundPredicate.java:42-50`），三路 OR 在那里是嵌套的二元树，靠递归天然覆盖全部分支。**读两个孩子在旧模型下是完备的。** +- **迁移换了输入模型但没换读法。** 新的 `ConnectorOr` 是拉平后的 N 元列表，照抄「读两个」就漏了。所以这是**移植时引入的回退**，不是忠实搬运上游缺陷。 +- **注意**：`master` 上已经有这个带缺陷的文件（`fe/fe-connector/fe-connector-trino/...` 在 `master` 上存在，由本次迁移的早期提交 apache/doris#62183 带入）。但 `master` 上 trino 目录仍走 fe-core 老路径（`fe/fe-core/.../trinoconnector/` 在 `master` 上还在，在本分支已删除），所以**只有本分支上这段代码是线上生效路径**。修复应视为修自己引入的回退，不要在提交信息里描述成上游缺陷。 + +## 四、用一个最小例子说明 + +假设一张

OR c_int = 3 OR c_int = 4` | 只剩 `IN (1, 2)`，丢 2 行 | `IN (1, 2, 3, 4)` | + +结果就是「查得越复杂，丢得越多」，且没有任何提示。 + +## 五、解决方案 + +### 5.1 目标状态 + +**`TrinoPredicateConverter.convertOr` 折叠全部分支。** 逐个转换所有 disjunct，收集成列表后交给 Trino 的 `TupleDomain.columnWiseUnion(List)` 一次性做列级并集： + +```java +private TupleDomain convertOr(ConnectorOr or) { + List> parts = new ArrayList<>(); + for (ConnectorExpression child : or.getDisjuncts()) { + // Not caught per-disjunct on purpose: dropping an OR arm narrows the pushed + // predicate and loses rows. Let the failure propagate so the caller degrades + // to TupleDomain.all() (no pushdown) instead. + parts.add(doConvert(child)); + } + if (parts.isEmpty()) { + return TupleDomain.all(); + } + return TupleDomain.columnWiseUnion(parts); +} +``` + +三个要点： + +1. **不要在循环里 catch 单个分支的异常。** `convertAnd`（`:102-112`）catch 并跳过失败的孩子是安全的——少一个 AND 条件只会让下推**变宽**，BE 会补算回来。OR 相反：少一支就是收窄，正是本缺陷的成因。让异常向上抛，由 `convert`（`:74-84`）的 catch 兜到 `TupleDomain.all()`，即「放弃下推、全量扫描」，语义安全。这与 iceberg 的处理方式一致（`IcebergPredicateConverter.java:212` 有一行注释明写 OR 是 all-or-nothing）。 +2. **`columnWiseUnion(List)` 用不了空列表。** 实测 trino-spi 435 的 `columnWiseUnion(List)` 在列表为空时抛 `IllegalArgumentException("tupleDomains must have at least one element")`，所以必须留空集合守卫返回 `TupleDomain.all()`。加上 5.1 的构造器校验后这条守卫在实践上不可达，但它是廉价的失败安全兜底，保留。 +3. **逐对折叠与一次性并集等价，但仍用 List 重载。** 列级并集里「一个列只有在所有分支都出现时才保留，其域取并集」，逐对折叠与整体计算结果相同；用 `List` 重载只是更直白，也少一次中间对象。 + +**`ConnectorOr` 构造器补齐契约。** 签名不变，只补校验与真拷贝，与同包 `ConnectorIn` 对齐： + +```java +public ConnectorOr(List disjuncts) { + Objects.requireNonNull(disjuncts, "disjuncts"); + if (disjuncts.size() < 2) { + throw new IllegalArgumentException( + "ConnectorOr requires at least two disjuncts, got " + disjuncts.size()); + } + this.disjuncts = Collections.unmodifiableList(new ArrayList<>(disjuncts)); +} +``` + +已核实**全部现存生产者都已满足这个前置条件**，加校验不会打破任何调用点： + +| 生产者 | 是否可能少于 2 个 | +| --- | --- | +|

明确不要顺手做的事 + +- **不要给 `ConnectorAnd` 一起加校验和拷贝。** 它是同样的浅包裹形状（`ConnectorAnd.java:34-37`），但已核实它的所有生产者（`WriteConstraintExtractor.java:86`、两个 Nereids 转换器、`ExprToConnectorExpressionConverter`）都已经守住了「只剩一个就不包 AND」，今天没有实际风险。把它一起改会让这次提交从「修一个会丢行的缺陷」变成「顺带整理公共类」，稀释了变更意图，也需要另做一遍全生产者核对。留给后续的一致性清理。 +- **不要顺手实现「剩余谓词」的精细化。** `TrinoConnectorDorisMetadata.java:292-296` 的注释里提到「未来可以把剩余 TupleDomain 映射回 ConnectorExpression 并清掉已完全下推的条件」。那是性能优化（少一次 BE 重算），与本缺陷无关，而且清错了就是另一次丢行。 +- **不要动 `convertAnd` 的「catch 并跳过」写法。** 它对 AND 是安全的（下推变宽），改成 all-or-nothing 只会降低下推率。 +- **不要在 fe-core 侧做任何改动。** fe-core 现阶段只出不进，这个缺陷完全在连接器与公共接口类里，无需碰引擎。 +- **不要写脚本或正则门禁去检查「是否遍历了 getDisjuncts()」。** 那是语言语义判断，本仓库已有结论：这类静态门禁误报比漏报更毒。用单元测试锁住行为即可。 + +## 六、怎么验证 + +### 单元测试要断言什么 + +在 `TrinoPredicateConverterTest` 里新增（现有 `CONVERTER` / `col()` / `expect()` / `singleValue()` 辅助方法直接可用，见 `:89-107`）： + +1. **三路同列 OR** —— `c_int=1 OR c_int=2 OR c_int=3` 必须得到 `c_int` 上含三个等值 range 的域。**这条在修复前必须失败**（改代码前先跑一次确认它红，这是本任务唯一的变异验证要求：如果它在旧代码上就绿，说明用例没打到缺陷）。 +2. **四路同列 OR** —— 证明修的是「全部分支」而不是把 2 改成 3。 +3. **三路跨列 OR** —— 例如 `c_int=1 OR c_bigint=2 OR c_str='x'`，列级并集下没有任何列在所有分支中都出现，结果必须是 `TupleDomain.all()`（放弃下推、不收窄）。这条锁住「不要为了下推而编造约束」。 +4. **含不可转换分支的 OR** —— 例如 `c_int=1 OR c_int=2 OR <一个裸列引用>`，结果必须是 `TupleDomain.all()`，**不能**是 `c_int IN (1,2)`。这条正面锁住 5.1 里「不要 per-disjunct catch」的决定，是防止本缺陷以另一种形态复活的关键用例。 +5. **保留现有的两路 OR 用例不改**，作为不回退的基线。 + +在新建的 `ConnectorOrTest` 里断言：0 个和 1 个分支抛 `IllegalArgumentException`；2 个及以上正常；构造后往调用方原 `ArrayList` 里再 `add` 一个分支，`getDisjuncts()` 的大小不变（证明是真拷贝）。 + +### 命令 + +单模块测试（必须禁用 maven build cache，否则 surefire 会被静默跳过而报 BUILD SUCCESS）： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -pl

的查询与结果断言。**这一步需要 docker 外部环境，本 session 通常跑不了**——补了用例后如实标注「未在本地执行」，不要声称已通过。单元测试已经能覆盖转换逻辑本身，端到端只是额外保险。 + +## 七、风险与回退 + +- **风险很低。** 生产改动是一个私有方法的循环化，加上一个公共构造器的前置校验。改动方向是「让下推更完整」，不会产生新的收窄。 +- **唯一需要留意的是新加的构造器校验会硬抛异常。** 已逐一核对全部生产者与测试用例都传 2 个以上（见 5.1 的表），并且 `mvn test-compile` + 全量单测能把遗漏暴露出来。若后续有人在别处构造单分支 OR，会立刻在构造点抛错而不是静默降级——这是刻意选择：单分支 OR 是调用方的逻辑错误，应当被发现。 +- **下推变完整后，某些查询扫到的数据会比修复前多。** 这不是回退，是本来就该读的数据。但如果有依赖旧（错误）行数的回归用例基线，需要更新基线而不是回滚修复。 +- **回退方式**：两个文件各自独立可回滚。若只想回退构造器校验、保留转换器修复，也是可行的——转换器的修复不依赖校验。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`：

NULL」，方向完全相反；要改成「右边是非空字面量就翻成等值比较，右边是空值字面量才翻成 IS NULL」，与 iceberg / trino / es 三家已经写对的做法一致。 + +## 二、背景：现在的代码是怎么写的 + +谓词下推的入口是 `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonPredicateConverter.java`。它把引擎交下来的中立表达式树（`ConnectorExpression`）翻译成 paimon 自己的 `Predicate`，翻不出来就返回 `null`，让 BE 端自己再过滤一遍——这是安全的放宽方向。 + +出问题的是比较表达式的翻译函数 `convertComparison`（`PaimonPredicateConverter.java:144-178`）： + +```java +Object value = convertLiteralValue(literal, fieldTypes.get(idx)); // :156 +if (value == null) { // :157 + return null; // :158 +} +switch (cmp.getOperator()) { + case EQ: + return builder.equal(idx, value); // :162 + ... + case EQ_FOR_NULL: + return builder.isNull(idx); // :173-174 + default: + return null; +} +``` + +关键在于 `convertLiteralValue`（`PaimonPredicateConverter.java:244-247`）开头就写着： + +```java +if (literal.isNull()) { + return null; +} +``` + +也就是说：**空值字面量在 :156 就已经被变成 `null`，在 :157 被提前 return 掉了**。等执行流走到 :173 的 `case EQ_FOR_NULL` 时，右操作数一定是个非空字面量——却返回了 `builder.isNull(idx)`。 + +注意 `value == null` 在这里有两种完全不同的含义，代码把它们混在一起了：一是「字面量本身是空值」，二是「这个 paimon 类型故意不下推」（同文件里 FLOAT、CHAR、TIMESTAMP WITH LOCAL TIME ZONE 都会返回 `null`，见测试 `floatNotPushed` / `charNotPushed` / `ltzNotPushed`）。修复时必须靠 `literal.isNull()` 把两者区分开。 + +翻出来的谓词有两个下游消费点，都在 `PaimonScanPlanProvider.java`： + +- `:506` 把它交给 paimon 的 `ReadBuilder.withFilter`，在 FE 规划阶段做分区级 / 数据文件级裁剪； +- `:783` 把它序列化进 `paimon.predicate` 属性发给 BE 的 paimon JNI reader，在读取时再过滤一次。 + +顺带说明：paimon 连接器不声明「已消费某个 conjunct」，所以原始条件仍会作为残余过滤在 BE 上重算（`PluginDrivenScanNode.buildRemainingFilter`）。残余过滤只能再减行，不可能把 FE 阶段已经裁掉的文件找回来。 + +**同一个算子，其他四家都是对的：** + +| 连接器 | 位置 | 做法 | +| --- | --- | --- | +| iceberg | `IcebergPredicateConverter.java:245-251` 与 `:252-254` | 只有「值转换失败且 `literal.isNull()` 且算子是空值安全等于」才转 `Expressions.isNull`；非空时和普通等值走同一分支 | +| trino | `TrinoPredicateConverter.java:132-139` | 显式按 `((ConnectorLiteral) cmp.getRight()).isNull()` 分两支：`Domain.onlyNull` 还是 `Range.equal` | +| es | `EsQueryDslBuilder.java:396-405` | `value == null` 走 `must_not exists`，否则走 term 查询；并有两个专测 `EsQueryDslBuilderTest.java:176` 与 `:201` | +| maxcompute | `MaxComputePredicateConverter.java:172-173` | 注释说明 ODPS 无对应算子，落到 default 直接放弃下推 | + +**归责（必须写清）**：这不是本次连接器迁移引入的回退。`git show master:fe/fe-core/src/main/java/org/apache/doris/datasource/paimon/source/PaimonPredicateConverter.java` 里的老实现，在 `binaryExprDesc` 中同样是先 `if (value == null) return null;`，再 `case EQ_FOR_NULL: return builder.isNull(idx);`——写法逐字相同。这是上游既有缺陷的忠实移植，本任务是顺手把它修掉。 + +## 三、为什么这是个问题 + +1. **翻译方向相反，不是收窄而是错。** 下推的容许方向只有「放宽」（多读点、让 BE 再过滤）。把「等于 5」翻成「为空」既不是原条件的超集也不是子集，两者的结果集是互斥的。 +2. **后果是静默少行。** FE 阶段按「IS NULL」裁剪，含 `c=5` 的数据文件根本不会进入扫描列表；BE 的残余过滤只能删行，补不回来。用户观察到的现象是：`WHERE c <=> 5` 返回 0 行（或只剩恰好也满足 IS NULL 的行），**没有任何报错、没有 warning**，`EXPLAIN` 里看到的裁剪后分区数也偏小。 +3. **默认会话下这条缺陷目前是潜伏的，但仍必须修。** 这一点是对早期调研结论的修正：Nereids 有一条改写规则 `NullSafeEqualToEqual`（`fe/fe-core/src/main/java/org/apache/doris/nereids/rules/expression/rules/NullSafeEqualToEqual.java:66-87`），在过滤条件位置只要有一边不可为空（字面量恒不可为空），就会把 `c <=> 5` 提前改写成 `c = 5`，所以走普通 `WHERE` 时坏分支通常到不了连接器。但是： + - 这条规则带 `ExpressionRuleType.NULL_SAFE_EQUAL_TO_EQUAL` 标签，可以被会话变量 `disable_nereids_rules` 关掉（`ExpressionPatternRules.java:78/95/111` 按该标签查 `disableRules` 位图）。关掉之后就是一条实打实的错误结果查询。 + - 连接器的翻译正确性不能建立在「某条可关闭的优化规则一定先跑过」之上。等值下推是连接器自己的契约义务。 + - 一旦坏分支出现在 OR 里（`convertOr`，`PaimonPredicateConverter.java:132-142`），错误的那一支会污染整个 OR 谓词，影响范围比单个 conjunct 更大。 +4. **根因在公共接口一侧。** 比较算子的公共契约总共只有一行文字：`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/pushdown/ConnectorComparison.java:27` 写着 `Supported operators: EQ, NE, LT, LE, GT, GE, EQ_FOR_NULL.`，然后 `:41` 给了个 `EQ_FOR_NULL("<=>")` 的符号。没有任何地方写明「右操作数可能是空值字面量」、「空值安全等于的语义是什么」、「不能精确翻译时必须放弃下推、只准放宽不准收窄」。于是五个消费者各写一遍，四家写对一家写错。**补这段契约文字是另一个任务（下推表达式契约补全）的事，本任务不改 `ConnectorComparison`。** + +## 四、用一个最小例子说明 + +建一张 paimon 表，`c` 列可为空，写入三行：`c = 5`、`c = 7`、`c = NULL`。 + +```sql +-- 让优化器不要抢先把 <=> 改写掉，直接压到连接器的翻译逻辑上 +set disable_nereids_rules = 'NULL_SAFE_EQUAL_TO_EQUAL'; + +SELECT * FROM paimon_ctl.db.t WHERE c <=> 5; +``` + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +| --- | --- | --- | +| `WHERE c <=> 5` | 下推给 paimon 的是 `isNull(c)`；只有 `c IS NULL` 的文件被读进来，BE 再用原条件 `c <=> 5` 过滤 → **返回 0 行** | 下推 `equal(c, 5)` → 返回 `c = 5` 那一行 | +| `WHERE c <=> NULL` | 空值字面量在 `convertLiteralValue` 就被丢掉 → 整个条件不下推，BE 全量过滤 → 结果正确，只是白读数据 | 下推 `isNull(c)` → 结果同样正确，且能做文件级裁剪 | +| `WHERE c = 5` | 下推 `equal(c, 5)` → 正确（对照组，说明问题只在空值安全等于这一支） | 不变 | + +一句话：第一行现在是**错的**（少行），第二行现在是**对但浪费**的，本任务把两行都摆正。 + +## 五、解决方案 + +### 5.1 目标状态 + +`convertComparison` 里把「值转换失败」这个统一出口拆成两种情形，形状与 iceberg 对齐（先判空值安全等于的空值特例，再走原有 switch）： + +```java +Object value = convertLiteralValue(literal, fieldTypes.get(idx)); +if (value == null) { + // 只有 `col <=> NULL` 能在没有值的情况下翻译：它等价于 IS NULL。 + // 其他情况（普通比较遇空值字面量、或该 paimon 类型故意不下推）一律放弃下推。 + if (cmp.getOperator() == ConnectorComparison.Operator.EQ_FOR_NULL && literal.isNull()) { + return builder.isNull(idx); + } + return null; +} +switch (cmp.getOperator()) { + case EQ: + case EQ_FOR_NULL: // 右边是非空字面量时，`<=>` 与 `=` 的结果集完全一致 + return builder.equal(idx, value); + ... + // 原 `case EQ_FOR_NULL: return builder.isNull(idx);` 删除 +} +``` + +为什么非空时用 `equal` 是精确等价而不是放宽：`c <=> 5` 为真当且仅当 `c = 5`（`c` 为空时结果是 false 而非 unknown）。paimon 的 `Equal` 继承 `NullFalseLeafBinaryFunction`，空值本身不会匹配 `equal`，语义正好吻合。 + +**注意判定顺序**：必须先判 `literal.isNull()` 再判类型，不能只判「算子是 `EQ_FOR_NULL`」就返回 `isNull`——否则一个 FLOAT 列上的 `c <=> 1.5`（值转换因类型故意不下推而失败）又会被翻成 IS NULL，等于换个地方复发同一个 bug。 + +### 5.2 改动清单 + +| 文件 | 改什么 | +| --- | --- | +|

IS NULL 分支；`:173-174` 的 `case EQ_FOR_NULL` 从返回 `isNull` 改为与 `case EQ` 合并（fall-through 到 `builder.equal`）。两处都补注释说明为什么。 | +| `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonPredicateConverter.java` 类注释 | 类头注释里补一句「空值安全等于按右操作数是否为空值字面量分流」，与 iceberg 同类注释口径一致。可选但推荐。 | +|

`EQ`，需要再加一个能指定算子和空值字面量的辅助方法（`ConnectorLiteral.ofNull(type)` 已存在，见 `ConnectorLiteral.java:45`）。 | + +### 5.3 明确不要顺手做的事 + +- **不要改 `ConnectorComparison.java`**（不改那行 `Supported operators`、不改枚举、不加 javadoc 契约段落）。契约补全是另一个任务的范围，两个任务同时改同一行会互相打架。 +- **不要顺手修同一个文件里 LIKE 的收窄缺陷**（`convertLike`，`PaimonPredicateConverter.java:218-239`，含单字符通配符 `_` 的模式被当成前缀匹配）。那是独立的一条，单独一个任务、单独一次提交，便于回退定位。 +- **不要动 iceberg / trino / es / maxcompute 的转换器**。四家已核实为正确实现，改它们只会引入风险。 +- **不要在 `fe-core` 里加一个「统一改写空值安全等于」的公共 helper**。当前阶段 `fe-core` 数据源相关代码只出不进；而且在引擎侧统一改写会把连接器各自的翻译义务藏起来，下一个连接器照样会写错。 +- **不要去改 Nereids 的 `NullSafeEqualToEqual` 规则**，也不要为了「反正优化器会改写」就不修连接器。优化器改写是加分项，不是正确性依据。 +- **不要新增 `supportsXxx()` 能力位**。这不是「paimon 不支持某个能力」，而是「翻译写错了」，能力位在这里没有意义。 +- **不要写 shell / 正则的构建门禁**去校验「`case EQ_FOR_NULL` 后面不许接 `isNull`」。本仓库已有明确结论：静态门禁只适合存在性与前缀类不变量，要理解 switch 分支极性就等于在 shell 里写 Java 解析器，误报比漏报更毒。用单元测试 + 注释即可。 + +## 六、怎么验证 + +**单元测试（必须）**，加在 `PaimonPredicateConverterTest.java`，全部离线（转换器只需要一个 `RowType`，不需要 catalog）： + +1. `eqForNullWithNonNullLiteralPushesEqual`：INT 列上构造 `ConnectorComparison(EQ_FOR_NULL, col("id"), literal 5)`，断言产出 1 个谓词，且 `((LeafPredicate) p).function()` 是 `org.apache.paimon.predicate.Equal`（可用 `Assertions.assertSame(Equal.INSTANCE, leaf.function())`），`leaf.literals().get(0)` 等于 `5`。 + 注释要写清 WHY：**如果这里翻成 IS NULL，含 `id=5` 的数据文件会在 FE 规划阶段被裁掉，查询静默少行**。 +2. `eqForNullWithNullLiteralPushesIsNull`：同一列上用 `ConnectorLiteral.ofNull(...)`，断言 `function()` 是 `org.apache.paimon.predicate.IsNull`，且 `literals()` 为空。 +3. `plainEqWithNullLiteralNotPushed`：`ConnectorComparison(EQ, col, ofNull(...))` 必须一个谓词都不产生（普通等值遇空值字面量结果恒为 unknown，不能翻成 IS NULL 也不该翻成 equal）。 +4. `eqForNullOnNonPushableTypeNotPushed`：FLOAT 列上 `EQ_FOR_NULL` 配非空字面量 `1.5`——值转换会失败（FLOAT 故意不下推），断言产出为空，**不能**变成 IS NULL。这条专门守住 5.1 里提到的判定顺序。 + +**变异验证（必须做，写进测试注释）**：把改好的 `case EQ_FOR_NULL` 改回 `return builder.isNull(idx)` → 第 1 条测试必须变红；把第 4 条对应的守卫条件从 `literal.isNull()` 放宽成只判算子 → 第 4 条必须变红。两条测试各自能被对应的错误写法打红，才算测到了意图而不是行为快照。 + +**编译门禁（最强单一信号）**：全反应堆含测试源编译，**不许**加跳过测试编译的参数。 + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile -DskipTests +``` + +**跑测试**必须显式关掉 maven build cache，否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -pl fe-connector/fe-connector-paimon

`<=>` 用例。如果要补，注意两点：一是必须在用例里 `set disable_nereids_rules='NULL_SAFE_EQUAL_TO_EQUAL'`，否则优化器会先把条件改写掉，用例根本压不到连接器路径，改坏了也照样绿；二是断言要同时覆盖 `c <=> 非空值`（有行）、`c <=> NULL`（只出空值行）和 `c = 非空值`（对照）。这一项不阻塞本任务合并。 + +## 七、风险与回退 + +风险低。行为变化被严格限制在「算子是空值安全等于」这一条分支上，其余算子的代码路径逐字不变，第 3、4 条测试就是用来钉住这一点的。 + +唯一的新增行为是「`c <=> NULL` 现在会下推成 IS NULL」——这是从「不下推」变成「下推一个语义正确的 IS NULL」，属于新增裁剪能力。paimon 的 `isNull` 叶子谓词只依赖空值计数统计，与列类型无关，因此即使在 FLOAT / CHAR / 带本地时区时间戳这些故意不下推值比较的列上也是安全的（iceberg 就是这么做的）。如果评审希望把改动面压到最小，可以只做「非空字面量 → equal」这一半，把空值字面量继续留给 BE 过滤；两种方案都修掉了正确性缺陷，前者额外多一点裁剪收益。 + +回退：单文件 `git

会据此跳过本该被读到的数据文件，查询**静默少行**。本任务把这个下推收紧成「只有能证明等价时才下推，否则放弃下推」。 + +## 二、背景：现在的代码是怎么写的 + +Doris 把查询过滤条件翻成连接器可消费的表达式树（`ConnectorExpression`），`LIKE` 会变成 `ConnectorLike`。paimon 连接器用 `PaimonPredicateConverter` 把这棵树翻成 Paimon SDK 的 `Predicate`。 + +出问题的就是这个转换方法，`fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonPredicateConverter.java:233-238`： + +```java +String pattern = ((ConnectorLiteral) patternExpr).getValue().toString(); +if (!pattern.startsWith("%") && pattern.endsWith("%")) { + String prefix = pattern.substring(0, pattern.length() - 1); + return builder.startsWith(idx, BinaryString.fromString(prefix)); +} +return null; +``` + +即：**只要模式串不以 `%` 开头、且以 `%` 结尾，就把「去掉最后一个字符」的结果当作字面前缀**交给 Paimon 的 `startsWith`。除此之外的模式串（同一方法的 `:238`）返回 `null`，表示放弃下推——这部分是对的。 + +转换出来的谓词有两个消费点，都在 `PaimonScanPlanProvider.java`： + +- FE 规划期：`:488` 调转换器，`:506` `readBuilder.withFilter(predicates)`。Paimon SDK 在 `newScan().plan()` 里用这些谓词做分区裁剪与数据文件裁剪（该类的类注释 `:120-125` 明确说明 paimon 是「纯谓词驱动」的裁剪，连引擎给的分区集都不消费）。 +- BE 读取期：`:780-783` 再转换一遍，序列化进 `paimon.predicate` 交给 BE 的 Paimon JNI scanner，做行级过滤。 + +两条路都意味着：**下推的谓词一旦比原谓词严格，被裁掉的文件/被过滤掉的行 BE 侧再也补不回来**（BE 上仍挂着原始 `LIKE` 过滤，但它只能过滤已经读到的行，不能把跳过的文件读回来）。 + +两条相关事实也已核对： + +- `ConnectorLike` 的公共契约总共只有一句话——「A LIKE/REGEXP predicate: `value LIKE pattern`」（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/pushdown/ConnectorLike.java:24-26`），枚举只有 `LIKE` / `REGEXP` 两个值（`:32-35`）。**没有任何地方约定转义字符是什么、`%` 与 `_` 的方言、正则是部分匹配还是整串锚定、大小写敏感性，也没有约定「翻不精确就必须放弃下推」。** 契约缺失是这类实现错误能活下来的土壤。 +- Doris 的 `LIKE` 默认转义字符是反斜杠：BE 侧实现 `be/src/exprs/function/like.cpp` 的快速路径正则 `:58` 明确把 `\%` 与 `\_` 当成转义后的字面量处理，并在 `:815` 的 `remove_escape_character` 里去掉转义再做前缀/后缀/子串匹配；自定义 `ESCAPE` 走 `:980` 之后的 `has_custom_escape` 分支。也就是说 BE 自己**是**做了 paimon 这里缺的那层守卫。 + +**归责**：这不是本次迁移引入的回退。`git show master` 对比确认，老的 fe-core 实现 `master:fe/fe-core/src/main/java/org/apache/doris/datasource/paimon/source/PaimonPredicateConverter.java:164-165` 是完全相同的写法（`name.equals("like") && !s.startsWith("%") && s.endsWith("%")` → `startsWith(s.substring(0, s.length() - 1))`）。属于上游既有缺陷的忠实移植。 + +## 三、为什么这是个问题 + +违反的原则只有一条，但很硬：**谓词下推只允许放宽，不允许收窄。** 引擎把过滤条件交给数据源，是为了让数据源少读数据；数据源如果把条件理解得比原意更严格，就会跳过本该返回的数据，而引擎无法察觉——因为返回的行数看起来「合理」，只是少了。 + +用户能观察到的现象：**同一张 paimon 表、同一条带 `LIKE` 的 SQL，结果比正确答案少行**，且没有任何报错、日志或 `EXPLAIN` 提示。切到别的引擎（Spark 读同一张 paimon 表）结果不一致。这类问题在生产上极难定位，因为它不崩、不慢、只是答案不对。 + +具体有三种模式串会踩中（第三种是本次核实时新发现的，最初那轮调研里没有）： + +1. **含单字符通配符 `_`**：`LIKE 'a_c%'` 里 `_` 应匹配任意一个字符，被当成字面下划线 → 下推 `startsWith("a_c")` → 真正含 `abc…` 的文件被裁掉。 +2. **含反斜杠转义**：`LIKE 'a\%%'` 的原意是「以字面量 `a%` 开头」，前缀应为 `a%`，但代码原样取到 `a\%`（带反斜杠）→ 下推 `startsWith("a\\%")` → 一行都匹配不上，结果可能直接空集。 +3. **`%` 夹在中间**：`LIKE 'a%b%'` 不以 `%` 开头、以 `%` 结尾 → 代码取前缀 `a%b` 并当成字面串 → 下推 `startsWith("a%b")`。这是同一个漏洞的第三种表现，修法相同。 + +一个附带确认（不用改）：`NOT LIKE` 不受影响。fe-core 把 `NOT` 翻成 `ConnectorNot`（`ExprToConnectorExpressionConverter.java:223-224`），而 paimon 的 `convertSingle`（`PaimonPredicateConverter.java:105-118`）没有 `ConnectorNot` 分支，直接返回 `null` 放弃下推。带 `ESCAPE` 子句的三参数 `LIKE` 也进不来（`ExprToConnectorExpressionConverter.java:117` 要求恰好两个子表达式）。 + +**诚实标注**：上述「少行」是从代码路径推断出来的，**尚未跑端到端验证**。所以本任务的第一步就是先写出一个能复现的端到端用例，先看到红，再动生产代码。 + +## 四、用一个最小例子说明 + +准备一张 paimon 表，两行数据，**分两次 insert**（这样两行落在两个不同的数据文件里，文件级统计就能触发裁剪）： + +```sql +-- 数据：第一个文件只有 'abc1'，第二个文件只有 'a_c1' +-- 查询（_ 是通配符，应该同时命中两行） +SELECT s FROM paimon_tbl WHERE s LIKE 'a_c%' ORDER BY s; +``` + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +| --- | --- | --- | +| `s LIKE 'a_c%'` | 下推 `startsWith("a_c")` → 只有 `'a_c1'` 所在文件被读，返回 1 行 | `_` 是通配符，两行都该返回：`a_c1`、`abc1` | +| `s LIKE 'a\%%'`（找以字面 `a%` 开头的值） | 下推 `startsWith("a\%")`（多了个反斜杠）→ 可能返回 0 行 | 返回所有以 `a%` 开头的行 | +| `s LIKE 'a%b%'` | 下推 `startsWith("a%b")`（`%` 被当字面量）→ 少行 | 返回以 `a` 开头、中间有 `b` 的行 | +| `s LIKE 'abc%'`（唯一安全的形态） | 下推 `startsWith("abc")` | 不变，继续下推 | + +修完之后的判断逻辑，用伪代码表达就是这么几行： + +``` +若 pattern 含 '_' 或含 '\' -> 不下推（返回 null） +去掉 pattern 末尾连续的 '%'，得到 body +若 body 为空，或 body 里还有 '%' -> 不下推 +否则 -> startsWith(body) +``` + +「含反斜杠就整体放弃」这条看起来粗，但它同时保证了「去掉末尾 `%`」不会误剥一个被转义的 `%`——因为到那一步已经确定串里没有反斜杠了。宁可少下推几个模式串，也不能下推错。 + +## 五、解决方案 + +### 5.1 目标状态 + +`PaimonPredicateConverter.convertLike` 只在**能证明等价**时才产出 `startsWith`，其余一切模式串返回 `null`（走不下推、由 BE 全量过滤，慢但正确）。不新增 SPI、不新增能力位、不改公共接口签名，只在连接器内部收紧一个判断。 + +建议把判断抽成同类里的一个私有静态方法，便于单测直接打： + +```java +/** + * Returns the literal prefix a Doris LIKE pattern is equivalent to, or null when the + * pattern cannot be proven equivalent to a prefix match. Declining is always safe; + * narrowing is not (Paimon prunes files from this predicate and BE cannot recover them). + */ +private static String literalPrefixOrNull(String pattern) +``` + +`convertLike` 里的调用形态： + +```java +String prefix = literalPrefixOrNull(pattern); +if (prefix == null) { + return null; +} +return builder.startsWith(idx, BinaryString.fromString(prefix)); +``` + +### 5.2 改动清单 + +| 文件 | 做什么 | +| --- | --- | +| `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonPredicateConverter.java` | 新增私有静态 `literalPrefixOrNull(String)`；`convertLike`（`:218-239`）里把 `:234-237` 那段替换为调用它。方法注释写清「Doris LIKE 默认转义符是反斜杠；不可精确翻译必须放弃下推，不得收窄」，并说明为什么收窄在这里是致命的（谓词同时用于 Paimon 文件裁剪与 BE JNI 行过滤，见 `PaimonScanPlanProvider:506` 与 `:783`）。 | +| `fe/fe-connector/fe-connector-paimon/src/test/java/org/apache/doris/connector/paimon/PaimonPredicateConverterTest.java` | 新增一组 LIKE 用例（该文件目前**一个 LIKE 用例都没有**，已核实 grep 无命中）。见第六节的断言清单。 | +| `regression-test/suites/external_table_p0/paimon/`（新增一个 groovy 文件，例如 `test_paimon_like_pushdown.groovy`） | 端到端复现 + 回归。用 `spark_paimon_multi`（框架方法在

`test_paimon_predict.groovy:30-38`。 | + +### 5.3 明确不要顺手做的事 + +- **不要去补 `ConnectorLike` 的公共契约文档/校验。** 「把逐算子语义与『不可精确翻译必须放弃下推』写进公共契约」是另一份任务的范围（见 audit-report.md 11.1 节末尾那段结论）。两边同时动 `fe-connector-api` 会互相冲突，本任务只修连接器实现。 +- **不要顺手修 es 那处同根因的问题。** 详见第八节：`EsQueryDslBuilder.java:512-522` 把 Doris 的 `REGEXP` 模式原样交给 ES 的 `regexp` 查询，锚定语义不同。是同一个根因的第二处，但涉及 ES 侧语义与另一套端到端环境，**是否同批修由排期决定**，不要塞进本任务。 +- **不要顺手扩大下推能力**（比如给 `%abc` 加后缀匹配、给 `%abc%` 加子串匹配）。那是性能增强，不是本任务的正确性修复，且要先核实所用 Paimon SDK 版本是否真有对应的 `endsWith` / `contains` 构造器。混在一起会让「这次到底修了什么」说不清。 +- **不要试图在连接器里建模排序规则与大小写敏感性。** 现状是 Doris `LIKE` 与 Paimon `startsWith` 都按字节比较，本任务不引入这个维度。 +- **不要顺手处理不含任何通配符的 `LIKE 'abc'`。** 现状是不下推（等价于 `=`，是个可下推机会），但那是增强不是修 bug。 +- **不要往 fe-core 加任何东西。** 当前阶段 fe-core 只出不进，这个修复完全在插件内部可解。 + +## 六、怎么验证 + +**第一步（先看到红）**：先写端到端用例并跑通「现在是错的」。用例形态：建一张带字符串列的 paimon 表，分三次 insert 分别写入 `abc1`、`a_c1`、`a%b1`，然后断言 + +- `WHERE s LIKE 'a_c%'` 返回 `a_c1` 与 `abc1` 两行（修复前预计只返回 1 行）； +- `WHERE s LIKE 'a\\%b%'` 返回 `a%b1`（修复前预计 0 行）； +- `WHERE s LIKE 'a%b%'` 返回 `a%b1` 与 `abc1`（`abc1` 里 `a` 后有 `b`）； +- `WHERE s LIKE 'abc%'` 仍返回 `abc1`（证明安全形态的下推没被误伤）。 + +如果某条在修复前就是绿的，**必须在实施记录里写清哪条没能复现**，不要默认「三条都复现」。文件级裁剪是否触发依赖 Paimon 的统计与读取路径（native raw-file 读 vs JNI 读），分文件写入是为了让裁剪确定触发；若仍不复现，改用 JNI 读路径的表（例如带 deletion vector 的表）再试一次。 + +**第二步：单元测试**（`PaimonPredicateConverterTest`）。断言的是「下推出来的 Paimon 谓词是什么」，不需要集群： + +| 输入模式串 | 期望 | +| --- | --- | +| `abc%` | 产出前缀 `abc` 的 `startsWith` | +| `abc%%` | 产出前缀 `abc` 的 `startsWith` | +| `a_c%` | **不下推**（转换结果为空列表） | +| `a\%%` | **不下推** | +| `a\_c%` | **不下推** | +| `a%b%` | **不下推** | +| `%abc%` / `%abc` / `abc` | 不下推（现状行为，作为回归护栏钉住） | +| `%` | 不下推 | + +测试要按 Rule 9 的要求把「为什么」写进注释：断言的不是「返回 null」这个实现细节，而是「翻不精确时必须放弃下推，因为收窄会让 Paimon 跳过文件而 BE 补不回来」。 + +**变异验证**（推荐做，成本很低）：把新方法里的 `_` 检查单独注释掉，确认 `a_c%` 那条单测转红；再恢复。证明这些测试不是「永远绿」的空壳。 + +**编译门禁**：全反应堆含测试源的 test-compile 是最强单一信号。 + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile -Dmaven.build.cache.enabled=false +``` + +不得使用任何跳过测试编译的参数。跑单测： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test -pl fe-connector/fe-connector-paimon -am \ + -Dtest=PaimonPredicateConverterTest -DfailIfNoTests=false -Dmaven.build.cache.enabled=false +``` + +`-Dmaven.build.cache.enabled=false` 不是可选项：不加它 surefire 会被 build cache 静默跳过，日志出现 `Skipping plugin execution (cached): surefire:test`，此时 `BUILD SUCCESS` 是空的（见 `plan-doc/HANDOFF.md` 构建坑第 1 条）。另外注意 `mvn ... | tail` 之后的 `$?` 是 `tail` 的退出码，要读日志里的 `BUILD SUCCESS` / `BUILD FAILURE` 行。 + +## 七、风险与回退 + +- **功能风险：低。** 改动只把「下推」变成「不下推」，不下推的语义永远是安全的（BE 侧仍有原始 `LIKE` 过滤），不会产生错误结果。 +- **性能风险：小而真实。** 原本被错误下推的那几种模式串（`_`、转义、中间 `%`）今后不再裁剪文件，这类查询会多读数据。这是把「快但错」换成「慢但对」，方向上没有争议；受影响的只是这三类模式串，最常见的 `'前缀%'` 形态完全不受影响。 +- **兼容性风险：无。** 不涉及 Gson 持久化类型标签、不涉及 thrift 有线格式、不改公共接口签名，插件独立打包也不影响 fe-core。 +- **回退**：单文件单方法改动，`git revert` 即可。端到端用例可独立保留（它断言的是正确行为，回退生产代码后会转红，这正是它该做的）。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` 11.1 节第（4）条：本任务的出处，含「行为后果是代码路径推断、未跑端到端验证」的原始标注，以及「（3）（4）是 paimon 连接器的问题，且与上游既有实现完全相同」的归责结论。 +- 同一节第（3）条：paimon 把空值安全比较 `列 <=> 5` 下推成「该列 IS NULL」，同样是「不可精确翻译却收窄」的错误，同样在 `PaimonPredicateConverter` 里。**是另一份任务**，但如果两个任务由同一人连着做，可以合并成一次端到端回归跑。 +- 同一根因的第二处（本任务范围之外）：`fe/fe-connector/fe-connector-es/src/main/java/org/apache/doris/connector/es/EsQueryDslBuilder.java:512-522` 把 Doris 的 `REGEXP` 模式串原样交给 ES 的 `regexp` 查询（`:522` 调 `regexpQuery`，`:661` 是其实现）。Doris 的 `regexp` 是部分匹配、Lucene 的 `regexp` 是整串锚定，语义不同。值得一提的是 ES 那侧本来就有干净的「拒绝下推」机制（`notPushDownList`），修起来有落点。 +- audit-report.md 第十五节整治路线表第 6 项 ——

侧的字段名带上，另一方面在公共接口 `ConnectorType` 的构造期把「字段名列表必须与子类型列表等长同序」这个到今天为止既无文档、也无校验的不变量变成硬约束，让下一个连接器无法再犯同样的错。 + +## 二、背景：现在的代码是怎么写的 + +### 2.1 类型是怎么从连接器流到引擎的 + +连接器不认识 Doris 的 `Type`，它只用公共接口里的 `ConnectorType`（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorType.java`）描述一个列的类型；引擎侧再由 `fe/fe-core/src/main/java/org/apache/doris/datasource/connector/converter/ConnectorColumnConverter.java` 把它翻成 Doris 的 `Type`。 + +`ConnectorType` 描述复杂类型的方式是**多条平行列表**（`:54-84`）：`children` 存子类型，`fieldNames` 存 STRUCT 的字段名，另外还有三组可选的按子元素元数据（`childrenNullable` / `childrenComments` / `childrenFieldIds` / `childrenCommentSpecified`）。类里一共 7 个公开构造器（`:86-148`）——6 个便捷构造器（`:86`、`:91`、`:96`、`:102`、`:108`、`:115`）加 1 个规范构造器（`:123`），便捷构造器全部层层委派到最长的那个规范构造器（`:123-148`），而**这个规范构造器只做了 `typeName` 的非空检查和不可变包装，对任何一条列表的长度都不做校验**。 + +工厂方法是给这些平行列表兜底的（`:162-215`）：`arrayOf` 保证 1 个子类型、`mapOf` 保证 2 个、`structOf(names, fieldTypes, ...)` 强迫调用方同时给出名字和类型。除 trino 与 es 之外的连接器都走工厂：`HmsTypeMapping.java:150`、`HudiTypeMapping.java:220`、`IcebergTypeMapping.java:89`、`MCTypeMapping.java:135`、`PaimonTypeMapping.java:200`，全部是 `structOf(names, types, ...)`，且 names 与 types 在同一个循环里成对填充。es 只用裸构造器包 ARRAY，且传的是 `Collections.singletonList(type)`（`EsTypeMapping.java:182-183`），个数恰好正确。 + +### 2.2 出问题的地方：trino 侧丢名 + +`fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoTypeMapping.java:107-112`： + +```java +} else if (type instanceof RowType) { + List children = new ArrayList<>(); + for (RowType.Field field : ((RowType) type).getFields()) { + children.add(toConnectorType(field.getType())); + } + return new ConnectorType("STRUCT", -1, -1, children); +} +``` + +循环里只 `add(field.getType())`，`field.getName()` 从头到尾没被读过（Trino 435 的 `RowType.Field` 提供 `Optional getName()`，trino 版本见 `fe/pom.xml:416`）；返回时用的是 4 参数裸构造器，`fieldNames` 槽位空缺。同一方法里相邻的 ARRAY（`:92-97`）与 MAP（`:98-106`）分支也用裸构造器，只是子类型个数恰好对，没有暴露出问题。 + +这个映射有两个消费点，都在 `TrinoConnectorDorisMetadata.java`：`:213` 是表结构（`DESCRIBE` / 查询分析看到的列类型），`:366` 是投影下推时回报给引擎的表达式类型。 + +### 2.3 引擎侧的宽容：缺名就编造 + +`ConnectorColumnConverter.java:258-273`： + +```java +private static Type convertStructType(ConnectorType ct) { + List children = ct.getChildren(); + List fieldNames = ct.getFieldNames(); + ArrayList fields = new ArrayList<>(); + for (int i = 0; i < children.size(); i++) { + String fieldName = i < fieldNames.size() ? fieldNames.get(i) : "col" + i; + ... +``` + +`:263` 这一行就是「编造」：名字缺了就用 `col` + 下标，**不告警、不抛错**。同一个文件里 ARRAY 与 MAP 也是同样的宽容风格：子类型列表为空时 `convertArrayType`（`:242-248`）返回 `ARRAY`、`convertMapType`（`:250-256`）在子类型不足 2 个时返回 `MAP`，一样没有任何提示。 + +同类的「缺名就编造」兜底在反方向（`ConnectorType` → 数据源类型）的连接器代码里还有四处：`HmsTypeMapping.java:239`、`IcebergSchemaBuilder.java:137`、`PaimonTypeMapping.java:289`、`MCTypeMapping.java:212`。也就是说这套「平行列表可以对不齐、对不齐就猜」的风格已经在五个地方复制过。 + +### 2.4 两条补充事实 + +- **这是迁移引入的回退，不是历史一直如此。** 迁移前 fe-core 里的老实现 `TrinoConnectorExternalTable.trinoConnectorTypeToDorisType()`（`git show master:fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorExternalTable.java`，ROW 分支）明确判断 `field.getName().isPresent()`，有名字就 `new StructField(name, childType)`，没名字才退化。所以真实字段名在迁移前是能被用户看到的。顺带一个细节：老实现对匿名字段用的是 `new StructField(childType)`，而 `fe/fe-type/src/main/java/org/apache/doris/catalog/StructField.java:46,69-70` 把这种字段一律命名为 `"col"`——多个匿名字段会重名，这本身是老实现的缺陷。 +- **现有单元测试断不出这个缺陷。** `fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoTypeMappingTest.java:123-133` 的 `testStructCarriesFieldTypes` 用 `RowType.field("a", INTEGER)` / `RowType.field("b", VARCHAR)` 造了带名字的 ROW，却只断言 `getChildren()` 的两个子类型名，从不看 `getFieldNames()`——名字丢没丢它都是绿的。 + +## 三、为什么这是个问题 + +**用户能观察到的后果（正确性）**：Doris 的 STRUCT 子字段访问是**按名字**解析的。`fe/fe-core/src/main/java/org/apache/doris/nereids/trees/expressions/functions/scalar/ElementAt.java:142-147`（struct 字段访问的类型推导）在按名字找不到字段时抛 `AnalysisException: the specified field name <名字> was not found: ...`。字段名一旦被换成 `col0` / `col1`，用户对着自己在 Trino / Hive 里定义的字段名写查询，一律在分析期就被拒；`DESCRIBE` 也只会显示编造出来的名字，用户连"真名是什么"都查不到。唯一还能用的访问方式是按序号（`s[1]`），而这恰好掩盖了问题——冒烟测试如果只用序号访问，看起来一切正常。 + +**公共接口层违反的设计原则**： + +1. **平行列表的对应关系是不变量，却既没有契约也没有校验。** `ConnectorType` 的类文档（`:25-53`）花了大段篇幅说明 `childrenNullable` / `childrenComments` / `childrenFieldIds` 三组可选元数据「parallel to children」以及为什么它们不参与 `equals`，但**对 `fieldNames` 与 `children` 的对应关系一个字都没写**，`getFieldNames()`（`:245-247`）甚至没有 javadoc；7 个构造器（6 个便捷 + 1 个规范，`:86-148`）也没有一处校验长度。于是"名字和类型必须等长同序"完全靠调用方自觉。 +2. **违约被静默吸收，而不是 fail loud。** 一个连接器写错了，代码能编译、表能加载、`DESCRIBE` 有输出，错误一路潜行到用户写查询的那一刻才以「字段不存在」的形式冒出来，而那时报错现场已经离真正的错误点（连接器的类型映射）很远了。 +3. **同一个坑对 ARRAY / MAP 一样敞开。** ARRAY 需要 1 个子类型、MAP 需要 2 个，公共接口同样不校验，引擎同样静默产出 `ARRAY` / `MAP`（`ConnectorColumnConverter.java:242-256`）。今天没人踩只是因为工厂方法恰好被大多数连接器用了。 + +另外值得注意的一点：`fieldNames` 是**参与** `equals` / `hashCode` 的（`ConnectorType.java:313-333`），也就是说字段名在这个类的设计里属于「类型的结构身份」，不是可有可无的附加元数据。丢名不是"少带了点信息"，是构造出了一个身份就不对的类型。 + +## 四、用一个最小例子说明 + +假设 Trino 侧（比如 trino-connector 挂 hive）有这么一张表： + +```sql +-- 数据源侧的表定义 +CREATE TABLE t (id int, s row(a int, b varchar)); +``` + +在 Doris 里通过 trino 连接器查它： + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +| --- | --- | --- | +| `DESC t;` | `s` 显示为 `struct` | `s` 显示为 `struct` | +| `SELECT s.a FROM t;` | 分析期报错 `the specified field name a was not found` | 正常返回 `a` 列的值 | +| `SELECT s['b'] FROM t;` | 同上，按名访问全军覆没 | 正常返回 | +| `SELECT s[1] FROM t;` | 恰好能跑（按序号访问） | 恰好能跑（行为不变） | + +公共接口这一侧的问题，用两行就能说明白： + +```java +// 今天：编译通过、构造成功、什么都不报，直到用户按名字查子字段才炸 +new ConnectorType("STRUCT", -1, -1, Arrays.asList(intType, strType)); // 名字全丢 +new ConnectorType("STRUCT", -1, -1, Arrays.asList(intType, strType), List.of("a")); // 名字只给一半 + +// 期望：上面两行都在构造点立刻抛 IllegalArgumentException +``` + +## 五、解决方案 + +### 5.1 目标状态 + +**(a) trino 侧把名字带上，并改用工厂方法。** `TrinoTypeMapping.toConnectorType` 的 ROW 分支改成： + +```java +} else if (type instanceof RowType) { + List rowFields = ((RowType) type).getFields(); + List names = new ArrayList<>(rowFields.size()); + List types = new ArrayList<>(rowFields.size()); + for (int i = 0; i < rowFields.size(); i++) { + RowType.Field field = rowFields.get(i); + // Trino ROW fields may be anonymous (RowType.anonymousRow); name them by position so that + // every field still gets a distinct, resolvable name. + names.add(field.getName().orElse("col" + i)); + types.add(toConnectorType(field.getType())); + } + return ConnectorType.structOf(names, types); +} +``` + +匿名字段的处理要写清楚：**用 `col` + 下标，而不是复刻老实现给所有匿名字段同名 `"col"` 的做法**。理由是重名字段在 Doris 侧一样无法按名访问，属于老实现的缺陷；`col` + 下标与引擎兜底（`ConnectorColumnConverter.java:263`）以及其它四个连接器的反向兜底命名完全一致，是本仓库既有约定。这是本任务唯一一处有意偏离迁移前行为的地方。 + +ARRAY / MAP 两个分支顺带改成 `ConnectorType.arrayOf(...)` / `ConnectorType.mapOf(...)`（等价改写，只为让「复杂类型一律走工厂」在这个文件里成为一眼可见的事实）。 + +**(b) 公共接口加构造期校验。** 在 `ConnectorType` 的规范构造器（`:123-148`）末尾调用一个新的私有静态方法，签名草案： + +```java +/** + * Fail loud on a malformed complex type: the parallel lists carried alongside {@link #getChildren()} + * must line up with it, and the three complex type tags have a fixed arity. + */ +private static void validateShape(String typeName, List children, List fieldNames, + List childrenNullable, List childrenComments, + List childrenFieldIds, List childrenCommentSpecified) +``` + +校验规则（`typeName` 用 `toUpperCase(Locale.ROOT)` 比对，与 `ConnectorColumnConverter.convertType` 的 `:229` 一致，避免 `"Struct"` 这种拼写绕过校验）： + +| 类型标签 | 规则 | +| --- | --- | +| `ARRAY` | `children.size() == 1` | +| `MAP` | `children.size() == 2` | +| `STRUCT` | `children` 非空；`fieldNames.size() == children.size()`；`fieldNames` 中不含 `null` | +| 以上三者 | 四组可选元数据列表（nullable / comments / fieldIds / commentSpecified）每一条要么为空（表示未携带），要么长度恰好等于 `children.size()`；比 `children` 长一定是调用方错了 | +| 其它标签 | **不校验**。`typeName` 是无词表的裸字符串，不能反过来断言「非复杂类型一定没有子类型」 | + +异常一律用 `IllegalArgumentException`（与同一构造器里 `Objects.requireNonNull` 的失败风格一致），消息里带上 `typeName` 和实际长度，例如 `STRUCT field name count (1) must match child type count (2)`。因为所有构造器与工厂方法都汇聚到这个规范构造器，一处落地即全覆盖。 + +**(c) 把契约写进类文档。** 在 `ConnectorType` 类 javadoc（`:25-53`）里补一段说明：`fieldNames` 与 `children` 是等长同序的平行列表、STRUCT 必须携带全部字段名、三个复杂类型标签的子类型个数固定、四组可选元数据要么不带要么带全，并注明这些在构造期强制。同时给 `getFieldNames()`（`:245-247`）补一行 javadoc 指向该契约。 + +**实施顺序**：(a) 必须与 (b) 在同一次改动里落地，且先改 trino——否则先加校验会让 trino 的表加载与现有 `TrinoTypeMappingTest` 立刻抛异常。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +| --- | --- | +| `fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoTypeMapping.java`（ROW 分支 `:107-112`，ARRAY `:92-97`，MAP `:98-106`） | ROW 分支收集字段名并改用 `ConnectorType.structOf(names, types)`，匿名字段用 `col` + 下标；ARRAY / MAP 改用 `arrayOf` / `mapOf`。加注释说明匿名字段命名的来由 | +| `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorType.java`（规范构造器 `:123-148`、类 javadoc `:25-53`、`getFieldNames()` `:245-247`） | 新增私有 `validateShape(...)` 并在规范构造器末尾调用；补齐平行列表契约文档 | +| `fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoTypeMappingTest.java`（`:123-133`） | 扩写 `testStructCarriesFieldTypes` 断言字段名；新增匿名

`regression-test/suites/external_table_p0/trino_connector/hive/`（可选） | 补一个 STRUCT 列的端到端用例，见第六节 | + +### 5.3 明确不要顺手做的事 + +- **不要动 `equals` / `hashCode`**（`:313-333`）。三组按子元素元数据被有意排除在类型身份之外，类文档 `:39-46` 已写明理由（类型身份等于结构形状，可空性与注释由消费方逐字段单独比较），改它会波及所有基于类型相等的模式变更检测。 +- **不要动 fe-core 的兜底分支**（`ConnectorColumnConverter.java:263` 的 `col` + 下标、`:242-256` 的 `ARRAY` / `MAP`）。三个理由：本阶段 fe-core 只出不进；构造期校验落地后这些分支已经不可能被合法构造的 `ConnectorType` 触发，留着当防御；把它们改成抛异常会把「某一列显示退化」升级成「整张表加载失败」，风险大于收益。 +- **不要顺手清理另外四处反方向的缺名兜底**（`HmsTypeMapping.java:239`、`IcebergSchemaBuilder.java:137`、`PaimonTypeMapping.java:289`、`MCTypeMapping.java:212`）。它们在 `ConnectorType` → 数据源类型的方向上，输入来自 fe-core 的转换器，与本缺陷不是同一条路径；逐一改属于扩大范围。 +- **不要给 ARRAY / MAP 发明 `fieldNames` 语义**。今天没有任何生产者给它们传名字，校验里也只要求「STRUCT 必须带全名字」，不去规定 ARRAY / MAP 必须为空——留出余地，但不主动定义新语义。 +- **不要把这 7 个构造器重构成 builder**，也不要给 `ConnectorType` 加新的工厂重载。校验落在唯一的规范构造器上就够了，重构会波及全部连接器。 +- **不要写 shell / 正则静态门禁**去检查「有没有人用裸构造器造 STRUCT」。本仓库已有结论：这类门禁只适合存在性与前缀类不变量，语言语义交给构造期校验加单元测试。 + +## 六、怎么验证 + +### 单元测试要断言什么 + +`TrinoTypeMappingTest`（扩写与新增）： + +1. **带名 ROW**：`RowType.rowType(RowType.field("a", INTEGER), RowType.field("b", VARCHAR))` 转换后 `getFieldNames()` 必须等于 `["a", "b"]`，且与 `getChildren()` 等长同序。**改代码前先跑这条，它必须是红的**——这是本任务的变异验证要求：如果它在旧代码上就绿，说明用例没打到缺陷。 +2. **匿名 ROW**：`RowType.anonymousRow(INTEGER, VARCHAR)`（Trino 435 提供）转换后名字为 `["col0", "col1"]`，锁住匿名字段各自拿到互不相同的名字这一决定。 +3. **嵌套**：`row(a int, b row(c int))` 转换后内层 STRUCT 的字段名也必须是 `["c"]`，证明递归路径同样带名。 +4. 现有的 ARRAY / MAP 用例（`:105-121`）保持不改，作为改用工厂方法后行为未变的基线。 + +新建 `ConnectorTypeTest`（`fe-connector-api`）： + +1. STRUCT 名字数少于子类型数、多于子类型数，两向都抛 `IllegalArgumentException`；断言消息里同时出现两个长度（否则报错对定位没帮助）。 +2. STRUCT 子类型列表为空、`fieldNames` 含 `null` 元素，抛异常。 +3. ARRAY 传 0 个或 2 个子类型、MAP 传 1 个或 3 个，抛异常。 +4. 任一组可选元数据列表比 `children` 长时抛异常；**为空时必须仍然合法**（`HudiTypeMapping` / `MCTypeMapping` 的 `structOf(names, types)` 就走这条路，`ConnectorColumnConverterTest.java:446-453` 也依赖它）。 +5. 大小写不敏感：`new ConnectorType("struct", -1, -1, children)`（无名字）同样抛异常，证明校验不能被拼写绕过。 +6. 合法路径全部不抛：`structOf` 的三个重载、`arrayOf` 两个重载、`mapOf` 两个重载，以及 `withChildrenFieldIds` 在 ARRAY（1 个 id）/ MAP（2 个 id）/ STRUCT（N 个 id）上的调用——后者对应 `IcebergTypeMapping.java:66-67,75-76,89` 的真实用法。 +7. 非复杂类型标签不受影响：`ConnectorType.of("JSONB")`、`of("DECIMALV3", 10, 2)` 正常。 + +### 现成的回归网 + +新校验最有价值的副作用是：所有构造复杂类型的既有测试都会变成它的回归网。这几个必须仍然全绿——`fe-core` 的 `ConnectorColumnConverterTest`（大量 `structOf` / `arrayOf` / `mapOf` + `withChildrenFieldIds`），以及 `HmsTypeMappingTest`、`HudiTypeMappingTest`、`HudiSchemaParityTest`、`IcebergTypeMappingReadTest`、`IcebergSchemaBuilderTest`、`IcebergNestedColumnEvolutionTest`、`MCTypeMappingTest`、`PaimonTypeMappingReadTest`、`PaimonTypeMappingToPaimonTest`、`HiveConnectorMetadataSchemaTest`。 + +### 命令 + +单模块测试（**必须禁用 maven build cache**，否则 surefire 会被静默跳过而报 BUILD SUCCESS）： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml \ + -pl fe-connector/fe-connector-api,fe-connector/fe-connector-trino -am \ + -Dmaven.build.cache.enabled=false \ + -Dtest=TrinoTypeMappingTest,ConnectorTypeTest -DfailIfNoTests=false test +``` + +编译门禁（最强的单一信号，验收必跑；`ConnectorType` 加了硬校验，要靠全反应堆确认没有别处的生产或测试源在构造不合法的复杂类型）： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile -Dmaven.build.cache.enabled=false +``` + +不要加任何跳过测试编译的参数。checkstyle 会扫测试源，新建文件要过。 + +### 端到端回归（可选，需要外部环境） + +`regression-test/suites/external_table_p0/trino_connector/hive/` 与 `external_table_p2/trino_connector/` 下**目前没有任何 STRUCT 列的用例**（已 grep 确认），所以这个缺陷此前不可能被端到端拦住。补一条最有价值：建一张带 `struct` 列的 hive 表（`test_trino_prepare_hive_data_in_case.groovy` 是"用例内建表"的现成模板），断言 `DESC` 输出的字段名以及 `SELECT s.a` 能跑通。这一步需要 docker 外部环境，本 session 通常跑不了——补了用例后如实标注「未在本地执行」，不要声称已通过。单元测试已经覆盖转换逻辑本身。 + +## 七、风险与回退 + +- **总体风险低。** trino 侧是一个 `else if` 分支内部的改写，方向是「补上本该带的信息」，不改变任何类型的形状与个数；`ConnectorType` 侧是纯前置校验，合法调用路径的行为完全不变。 +- **主要风险是新校验硬抛异常。** 已逐一核对全部生产侧构造点：只有 `TrinoTypeMapping`（本次修）与 `EsTypeMapping.java:182-183`（ARRAY 单子类型，合法）用裸构造器，其余连接器一律走工厂且名字与类型在同一循环成对填充；四组可选元数据的现有传参也都是等长或为空。测试源里的构造点由全反应堆 `test-compile` 加上第六节列出的既有测试兜住。若后续有人构造出对不齐的复杂类型，会在构造点立刻抛错而不是静默编造名字——这是刻意选择。 +- **用户可见变化：trino 目录下 STRUCT 列的字段名会从 `col0` / `col1` 变成真实名字。** 外部表结构不落盘持久化，升级后重新加载即生效，无需元数据迁移。如果有人此前把 `col0` 写进了查询或视图，那些写法会失效——但它们本来就是在依赖一个缺陷，并且真实名字恰好叫 `col0` 的情况仍然正常工作。 +- **回退**：两处改动互相独立，各自都是单文件局部改写，直接 revert 即可。注意若只 revert trino 侧而保留校验，trino 目录的 STRUCT 列会在表加载时抛异常——要回退就一起回退。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`： + - `### 11.1 四个有实际用户可见后果的缺陷` 第（2）条 —— 复杂类型字段名被丢弃，本缺陷的摘要条目； + - `### A.6 实现与接口定义不符（一致性）（24 条）` 第 116 条 —— 平行列表无契约无校验，原始判定与位置。 + - 同一章的第 124 条记录了 `ConnectorType.typeName` 的另一个问题（javadoc 说是「连接器自己的类型系统」，实际必须用 Doris 内部拼写，未知名字静默退化为 `UNSUPPORTED`）。它与本任务同在 `ConnectorType`，但**不在本任务范围内**：那是词表与文档问题，本任务只处理复杂类型的形状校验，不要混在一起改。 +- 相邻任务：`tasks/01-fix-trino-or-predicate-row-loss.md` 同样同时改 `fe-connector-trino` 与 `fe-connector-api`，但改的是 `TrinoPredicateConverter` 与 `ConnectorOr`，与本任务无文件重叠，两者可独立进行；两者采用同一种「在公共接口构造期 fail loud」的修法，实施时可互相参照措辞风格。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/05-fix-hudi-partition-timestamp-unit.md

`ConnectorPartitionInfo.getLastModifiedMillis()` 约定的单位是「epoch 毫秒」（1970 年以来的毫秒数，当前约 1.7×10¹²），hudi 连接器往这个字段里填的却是 Hudi 自己的时刻串 `yyyyMMddHHmmssSSS` 当成数字（约 2.0×10¹⁶，比墙上时钟大四个数量级）。引擎会拿这个值与当前时间相减来判断「这张表最近有没有在写」，减出来的值恒为 0，于是**分区 hudi 表（以及任何与它一起扫的查询）的 SQL 结果缓存永远不会启用**。本任务在连接器侧把时刻转成真正的 epoch 毫秒，引擎零改动。 + +## 二、背景：现在的代码是怎么写的 + +**（1）契约方。** `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorPartitionInfo.java:166-169`： + +```java +/** @return last-modified epoch millis, or {@link #UNKNOWN}. */ +public long getLastModifiedMillis() { + return lastModifiedMillis; +} +``` + +契约就这一句：epoch 毫秒，或者 `UNKNOWN`（`-1`，见 `:32`）。 + +**（2）hudi 连接器怎么填的。** 分区列举的公共收集点是 `HudiConnectorMetadata.collectPartitions`（`fe/fe-connector/fe-connector-hudi/src/main/java/org/apache/doris/connector/hudi/HudiConnectorMetadata.java:716`），它有两条支路，都把「最新已完成 instant」当作最后修改时间往下传： + +- 走 HMS 同步分区时（`:733`）：`return buildPartitionInfos(hmsNames, partKeyNames, latestInstant(handle));` +- 走 hudi 自己的元数据列举时（`:742-749`）：`HudiScanPlanProvider.latestCompletedInstant(metaClient)` 的结果作为 `Map.Entry` 的 key 传下去。 + +落笔的地方是 `buildPartitionInfos`（`:759-778`），第 775 行就是那个参数： + +```java +result.add(new ConnectorPartitionInfo(name, values, Collections.emptyMap(), + ConnectorPartitionInfo.UNKNOWN, ConnectorPartitionInfo.UNKNOWN, + instant, ConnectorPartitionInfo.UNKNOWN, // <- 第 775 行，这里应该是 epoch 毫秒 + orderedValues, Collections.emptyList())); +``` + +而 `instant` 是什么，`HudiScanPlanProvider.java:715-717` 与 `:725-727` 写得很清楚：从 timeline 取最新已完成 instant 的 `requestedTime()`（形如 `20240101120000000`），再 `Long.parseLong` 成 `long`；空 timeline 返回 `0L`。**它是一个把年月日时分秒毫秒直接拼起来的数字，不是时间戳。** + +**（3）引擎怎么用这个值。** 只有一个消费点：`fe/fe-core/src/main/java/org/apache/doris/datasource/mvcc/PluginDrivenMvccExternalTable.java:279` 把每个分区的值收进 `nameToLastModifiedMillis`，随后两个方法读它（hudi 既不声明 last-modified 新鲜度、也不提供 range 视图，因此两个方法都落到最后那条兜底分支）： + +- `getNewestUpdateVersionOrTime()`（`:803`，兜底分支 `:829`）——数据版本令牌，用于判断「表变没变」； +- `getNewestUpdateTimeMillisForCache()`（`:834`，兜底分支 `:848`）——**只**给 SQL 缓存的「安静窗口」门禁用，方法 javadoc（`MTMVRelatedTableIf.java:119-131`）明确写了它必须是「genuine WALL-CLOCK epoch-millis」。 + +门禁本体在 `fe/fe-core/src/main/java/org/apache/doris/qe/cache/CacheAnalyzer.java:263-277`： + +```java +long newestUpdateMillis = 0; +for (CacheTable cacheTable : tblTimeList) { // 所有被扫的表取最大值 + newestUpdateMillis = Math.max(newestUpdateMillis, cacheTable.latestPartitionUpdateMillis); +} +if (now == 0) { + now = nowtime(); // System.currentTimeMillis() + now = Math.max(now, newestUpdateMillis); // :273 +} +if (enableSqlCache() + && (now - newestUpdateMillis) >= Config.cache_last_version_interval_second * 1000L) { +``` + +`cacheTable.latestPartitionUpdateMillis` 正是 `getNewestUpdateTimeMillisForCache()` 的返回值（`:512`）。`cache_last_version_interval_second` 默认 30（`fe/fe-common/src/main/java/org/apache/doris/common/Config.java:1426`）。 + +顺带核实两件事，避免把影响面说过宽： + +- 外部表进 SQL 缓存要先打开会话变量 `enable_hive_sql_cache`（默认 false，门在 `fe/fe-core/src/main/java/org/apache/doris/nereids/rules/analysis/BindRelation.java:855-857`）。**没打开这个开关时本缺陷不可见。** +- 无分区 hudi 表根本走不到这里：它的分区列举返回空（`HudiConnectorMetadata.java:718-720`），版本令牌算出来是 0，`SqlCacheContext.addUsedTable` 的 `version <= 0` 兜底（`fe/fe-core/src/main/java/org/apache/doris/nereids/SqlCacheContext.java:201-206`）直接把它标成不可缓存。**所以本任务修的是分区 hudi 表。** + +**（4）别的连接器没有这个问题**（已逐个核对 `new ConnectorPartitionInfo(` 的调用点）：paimon 填 `partition.lastFileCreationTime()`（毫秒，`PaimonConnectorMetadata.java:1290`），hive / iceberg / maxcompute 走不带统计字段的构造器，全是 `UNKNOWN`。**hudi 是唯一一个填了非毫秒值的连接器。** + +## 三、为什么这是个问题 + +违反的原则是：**公共接口写明了单位的字段，实现方必须按那个单位填**。这不是风格问题——引擎拿它跟墙上时钟做减法，单位错了减出来的数没有任何意义，而且错的方向让缺陷完全隐形。 + +推演一遍第二节那段门禁代码（假设一张 hudi 表最新 instant 是 `20240101120000000`）： + +1. `newestUpdateMillis = 20240101120000000`（≈ 2.0×10¹⁶）； +2. `now = System.currentTimeMillis()` ≈ 1.7×10¹²，接着 `now = Math.max(now, newestUpdateMillis)` 把 `now` 拉到 20240101120000000； +3. `now - newestUpdateMillis == 0`，永远 `< 30000` → 门禁永不放行。 + +注意第 2 步那个 `Math.max`（它本来是为云上 FE 与元数据服务时钟不一致准备的）把这个缺陷变成**永久性**的：不是「等 30 秒就好」，而是无论过多久都为 0。 + +用户能观察到什么：打开 `enable_hive_sql_cache` 后，`EXPLAIN PHYSICAL PLAN` 里 hudi 查询永远看不到 `PhysicalSqlCache`，重复执行同一条 SQL 每次都完整重扫；更隐蔽的是**一张 hudi 表会污染整条查询**——门禁取所有被扫表的最大值，所以「olap 表 join hudi 表」的查询也一起失去 SQL 缓存。不会算错数据，纯粹是性能损失，但影响面是所有分区 hudi 表的查询。 + +顺带说明这个值的另一个身份：它同时被当作 hudi 的数据版本令牌（`getNewestUpdateVersionOrTime`）与每分区的物化视图新鲜度快照（`MTMVTimestampSnapshot`）。这两处只要求「变了就不同、单调不减」，instant 和 epoch 毫秒都满足，所以那两个功能今天是好的——本任务只把单位改对，不改这两处的语义。 + +## 四、用一个最小例子说明 + +```sql +-- 会话开关：外部表 SQL 缓存的总开关（默认关） +SET enable_sql_cache = true; +SET enable_hive_sql_cache = true; + +-- 一张分区 hudi 表，最后一次写入发生在很久以前（远超 30 秒的安静窗口） +EXPLAIN PHYSICAL PLAN SELECT count(*) FROM hudi_catalog.db.one_partition_tb;

| +| `SELECT * FROM olap_tbl JOIN hudi_tbl ...` | hudi 表的值参与取最大值，把整条查询的门禁也顶死 | 两张表都安静 → 整条查询可缓存 | +| 刚往 hudi 表写完就查 | 不缓存（碰巧是对的，但理由是错的） | 不缓存（因为真的在 30 秒安静窗口内） | + +单位换算本身就一行事： + +``` +现在填的：

+ +hudi 连接器在把分区信息交给引擎之前，用 Hudi 自己的工具把 instant 转成 epoch 毫秒；raw instant 继续留在它本来该在的地方（查询快照 `beginQuerySnapshot` 的 `snapshotId`、时间旅行的 handle 属性），不再冒充「最后修改时间」。公共接口只补文档。 + +在 `HudiScanPlanProvider` 里新增两个方法（放在既有 `requestedTimeToInstant`，`:725` 旁边，保持「纯静态、可离线单测」的既有风格）： + +```java +/** 表的 instant 是按哪个时区生成的（hoodie.table.timeline.timezone，默认 LOCAL）。 */ +static ZoneId timelineZone(HoodieTableMetaClient metaClient); + +/** + * Hudi instant（yyyyMMddHHmmssSSS 数字）-> epoch millis，即 + * ConnectorPartitionInfo#getLastModifiedMillis 契约要求的单位。instant <= 0（空 timeline）返回 0。 + */ +static long instantToEpochMillis(long instant, ZoneId zone); +``` + +实现建议（这四个 API 已用 `javap` 在 `hudi-common:1.0.2` 的 jar 里核实存在）：`HoodieInstantTimeGenerator.fixInstantTimeCompatibility(String)` 把 14 位的秒级老 instant 补齐成 17 位，`HoodieInstantTimeGenerator.MILLIS_INSTANT_TIMESTAMP_FORMAT`（值为 `"yyyyMMddHHmmssSSS"`）作为格式，`HoodieTableMetaClient.getTableConfig().getTimelineTimezone().getZoneId()` 拿时区。**不要**改用 `HoodieInstantTimeGenerator.parseDateFromInstantTime`：它一行就能用，但时区取自一个全局静态开关，对显式配了 `timeline.timezone=UTC` 的表会引入一个时区偏移量级的偏差（详见第七节）。 + +解析失败时 **log warn + 返回 0**，不要抛：这个值只喂缓存与新鲜度启发式，而它所在的分区列举是查询热路径，为一个统计字段炸掉整张表的查询不划算。返回 0 等于「无可靠变更信号」，引擎侧已有兜底（`SqlCacheContext` 的 `version <= 0` 分支）。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +| --- | --- | +| `fe/fe-connector/fe-connector-hudi/.../HudiScanPlanProvider.java` | 新增 `timelineZone` 与 `instantToEpochMillis`（见 5.1）。javadoc 写清：这是给公共 `lastModifiedMillis` 字段用的单位转换，raw instant 只用于 timeline 定位与快照 id，两者不要混用。 | +| `fe/fe-connector/fe-connector-hudi/.../HudiConnectorMetadata.java` | ① `:742-749` 那个 `metaClientExecutor.execute` 里，把 `Map.Entry` 的 key 从 `latestCompletedInstant(metaClient)` 换成 `instantToEpochMillis(latestCompletedInstant(metaClient), timelineZone(metaClient))`——转换在**同一个已建好的 metaClient 上**完成，零额外远程调用。② 新增 `long latestInstantMillis(HudiTableHandle handle)`（镜像既有 `latestInstant`，`:785-789`），供 HMS 同步支路 `:733` 使用。③ `buildPartitionInfos`（`:759-760`）第三个参数改名 `instant` → `lastModifiedMillis`，并同步修正它的 javadoc（`:752-758` 现在写的是「= the pinned instant」）。 | +| `fe/fe-connector/fe-connector-api/.../ConnectorPartitionInfo.java` | 只改 `getLastModifiedMillis()` 的 javadoc（`:166`）：补一句「引擎会拿它与墙上时钟相减做 SQL 缓存的安静窗口门禁（`CacheAnalyzer`），填非 epoch 毫秒的值会**静默关闭**该表及与它同查询的所有表的 SQL 缓存」。签名与字段不动。 | +| `fe/fe-connector/fe-connector-hudi/src/test/.../HudiConnectorPartitionListingTest.java` | 在「item 1: instant string → long」那组（`:58-70`）后面加一组单位转换用例；同时修 `buildPartitionInfosStampsInstantAndValues`（`:139-156`）——它现在断言 instant 原样透传（`:149`），改成传一个毫秒值并断言透传。`:221` 与 `:234` 那两处传 `5L` / `88L` 的用例不受影响（转换已挪到调用点之前，`buildPartitionInfos` 只负责透传）。 | +| `regression-test/suites/external_table_p2/hudi/test_hudi_sqlcache.groovy`（新增） | 端到端：对一张分区 hudi 表断言 `PhysicalSqlCache` 出现。骨架直接抄 `regression-test/suites/external_table_p0/iceberg/test_iceberg_sqlcache.groovy`（那份是同一个门禁上 iceberg 微秒单位问题的回归，`:18-30` 的 WHY 注释、`:45-52` 读 `cache_last_version_interval_second` 自适应等待、`:54-66` 的 `assertHasCache` 断言助手都可以照用）；catalog 建法与表名抄 `regression-test/suites/external_table_p2/hudi/test_hudi_partition_prune.groovy:18-52`（`regression_hudi.one_partition_tb`）。 | + +### 5.3 明确不要顺手做的事 + +- **不要给 `ConnectorPartitionInfo` 加「instant 原值」属性键。** 已核实 fe-core 里没有任何地方读 `ConnectorPartitionInfo.getProperties()`（唯一消费 `lastModifiedMillis` 的是 `PluginDrivenMvccExternalTable:279`；`ShowPartitionsCommand:299-312` 只读名字/行数/大小/文件数）。表级 instant 已经由 `beginQuerySnapshot` 的 `snapshotId` 承载（`HudiConnectorMetadata.java:437-449`）。加一个没有消费方的键属于投机。 +- **不要动 fe-core 的任何文件。** 引擎侧已经把「版本令牌」与「安静窗口门禁值」拆成两个方法了（`CacheAnalyzer.java:259-262`、`:505-513` 的注释就是这次拆分留下的），修 hudi 不需要引擎配合。当前阶段 fe-core 只出不进。 +- **不要顺手让无分区 hudi 表也能进 SQL 缓存。** 那要给 hudi 补一条表级新鲜度通道（`getTableFreshness` / range 视图之一），是独立的能力扩展，且无分区 iceberg 表今天同样不可缓存（见 iceberg 那份用例的注释），行为一致，不构成缺陷。 +- **不要改 `beginQuerySnapshot` 里的 `snapshotId`。** 它必须保持 raw instant：物化视图的表级快照与时间旅行都靠它，换成毫秒会打断与 timeline 的对应关系。 +- **不要顺手统一「其它连接器的分区统计字段」**（例如给 hive 补分区最后修改时间）。那是能力增强，与本次单位修复无关。 +- **不要为这类单位约束加静态门禁**（shell/正则）。「某个 long 是不是 epoch 毫秒」不是文本可判定的，本仓库已有结论：这类门禁只适合存在性/前缀类不变量。约束靠 javadoc + 单测钉住。 + +## 六、怎么验证 + +**第一步：单元测试（不需要集群，是本任务的主要证据）。** 加在 `HudiConnectorPartitionListingTest`： + +| 用例 | 断言 | +| --- | --- | +| `instantToEpochMillis(20240101120000000L, ZoneOffset.UTC)` | 等于 `1704110400000L`（2024-01-01T12:00:00Z），并断言落在 `[1e12, 1e13)` 区间——**量级断言就是这次的核心判据** | +| 14 位秒级老 instant（如 `20240101120000L`） | 转换成功且与上面同一天同一小时的量级一致。**不要硬编码猜测毫秒补位**，先跑出来看 hudi 的 `fixInstantTimeCompatibility` 实际补什么（jar 里的常量 `DEFAULT_MILLIS_EXT = "999"`），再把实际值钉进断言 | +| `instantToEpochMillis(0L, zone)` | 等于 `0L`（空 timeline 语义不变，仍是 `>= 0`，能过 `getNewestUpdateVersionOrTime` 的 `v >= 0` 过滤） | +| 不可解析的数字（如 `5L`） | 返回 `0L`，不抛异常 | +| **意图用例（最重要的一条）** | 用「一小时前」的本地时间拼出 instant 串再转换，断言 `System.currentTimeMillis() - 转换值` 落在约 1 小时 ± 5 分钟内。这条用例直接编码了 Rule 9 要求的「为什么」：这个值必须能被「当前时间减去它 = 这张表安静了多久」这个门禁正确解读。**回退到 raw instant 会让这个差值变成大负数，用例转红。** | + +**变异验证（要做，成本极低）**：把 `HudiConnectorMetadata` 里的转换调用改回直接传 instant，确认上面那条意图用例转红；恢复。证明这组测试不是永远绿的空壳。 + +**第二步：端到端回归（需要 hudi 外部环境，`enableHudiTest=true`）**。新增用例 `test_hudi_sqlcache`：开 `enable_sql_cache` 与 `enable_hive_sql_cache`，对分区表 `regression_hudi.one_partition_tb` 断言 `EXPLAIN PHYSICAL PLAN` 里出现 `PhysicalSqlCache`。测试环境的 hudi 数据是预置的静态数据，早已超出 30 秒安静窗口，因此**修复前必然红、修复后必然绿**，判据干净。`use_hive_sync_partition` 建议像 `test_hudi_partition_prune` 那样两个取值各跑一遍，因为两条支路的转换点是分开改的（5.2 的 ① 与 ②）。 + +同时回跑既有的 hudi 物化视图相关用例，确认新鲜度语义没被打断（换单位后首次比较会判定「变了」，触发一次多余刷新，属预期）：`test_hudi_mtmv`、`test_hudi_rewrite_mtmv`、`test_hudi_olap_rewrite_mtmv`、`test_hudi_partition_prune`。 + +**第三步：编译门禁。** 全反应堆含测试源的 test-compile 是最强单一信号： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile -Dmaven.build.cache.enabled=false +``` + +不得使用任何跳过测试编译的参数。跑单测： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test -pl fe-connector/fe-connector-hudi -am \ + -Dtest=HudiConnectorPartitionListingTest -DfailIfNoTests=false -Dmaven.build.cache.enabled=false +``` + +`-Dmaven.build.cache.enabled=false` 不是可选项：不加它 surefire 会被 build cache 静默跳过（日志出现 `Skipping plugin execution (cached): surefire:test`），此时 `BUILD SUCCESS` 是空的。另外 `mvn ... | tail` 之后的 `$?` 是 `tail` 的退出码，要读日志里的 `BUILD SUCCESS` / `BUILD FAILURE` 行。 + +## 七、风险与回退 + +- **正确性风险：无。** 这个字段不参与读数据、不参与分区裁剪，只喂缓存门禁与新鲜度比较。改错了最坏也只是缓存启用早晚，不会出错行。 +- **数据版本令牌一次性变小。** 同一个值也是 hudi 的版本令牌，修复后从 ~2.0×10¹⁶ 掉到 ~1.7×10¹²。唯一会因此报错的地方是 SQL 字典：`Dictionary.hasNewerSourceVersion`（`fe/fe-core/src/main/java/org/apache/doris/dictionary/Dictionary.java:282-286`）在新版本小于已记录版本时抛异常。已核实 `srcVersion`（`:107`）**没有** `@SerializedName`，即不持久化、FE 重启归零，而部署这个改动本身就要重启 FE，所以不存在跨重启的比较。**结论：不构成实际风险，但要在 PR 说明里写明这条推理，别让评审自己去猜。** +- **物化视图会多刷一次。** 每分区的 `MTMVTimestampSnapshot` 值换了单位，物化视图元数据里持久化的上次刷新快照与新值不等，会触发一次刷新。之后恢复稳定。 +- **时区偏差（已按 5.1 的方案规避，这里记录残余）。** instant 串本身不带时区，按 `hoodie.table.timeline.timezone` 生成（默认 `LOCAL`）。5.1 的方案从表配置读时区，所以显式配 `UTC` 的表是准的；配 `LOCAL` 的表按 FE 本地时区解析，若写入方与 FE 不在同一时区，转换值会有一个时区偏移量级的误差。这只会让缓存提前或推迟启用（最坏推迟约一个时区偏移的时长，因为 `now = Math.max(now, newest)` 会把未来值顶住），不影响正确性，且 `LOCAL` 语义本身就是「按写入方本地时区」，Doris 无从得知写入方时区——不要试图猜。 +- **单调性。** instant 到毫秒的映射是同序的（hudi 自己比较 instant 时也把 14 位按补 `999` 处理），因此版本令牌仍然单调不减，字典与物化视图的单调性要求不被破坏。 +- **回退**：改动集中在 hudi 连接器两个文件，`git revert` 即可。端到端用例可以留着（回退后它会转红，这正是它该做的事）。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` 附录 A.6 第 120 条 —— 时刻串冒充 epoch 毫秒：本任务的出处，给出了「契约是 epoch 毫秒 / hudi 填 instant / 把 SqlCache 安静窗口门禁算坏」的判定与符号定位。 +- 同一份报告第十节 10.2（主题七「语义与契约不清」里数值单位那一小节）—— 单位与未知值无统一约定，以及第十五节整治路线表第 6 项 —— 修四个真实缺陷的排期：把它与 trino 三路 OR 丢行、paimon 两处谓词收窄归为同一批，理由是有用户可见后果、不应排在设计整治之后。 +- 同一门禁上已经修过的先例（**动手前建议先读**）：`regression-test/suites/external_table_p0/iceberg/test_iceberg_sqlcache.groovy:18-30` 的注释完整记录了 iceberg「微秒喂进毫秒门禁」的同类问题及其修法，`MTMVRelatedTableIf.getNewestUpdateTimeMillisForCache`（`fe/fe-core/src/main/java/org/apache/doris/mtmv/MTMVRelatedTableIf.java:119-131`）与 `ConnectorMvccPartitionView.getNewestUpdateWallClockMillis`（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/mvcc/ConnectorMvccPartitionView.java:126-137`）就是那次拆分留下的接口。iceberg 走的是 range 视图分支，hudi 走兜底分支，所以不能直接复用它的通道——但两者是同一个坑的两种表现。 +- `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/scan/ConnectorScanRange.java:56` 附近是**同类的第三处**单位违约（契约写字节数、maxcompute 在行偏移模式返回行数，报告条目 121）。是另一份任务，不要塞进本任务，但两者可以共享同一条经验：公共接口凡写了单位的字段，都该有一条量级单测钉住。 diff --git

是「引擎实现、连接器消费」的接口，共 19 个方法，其中只有 `getCatalogName()`（`:39`）和 `getCatalogId()`（`:42`）是抽象的，其余 17 个都带默认实现，而这些默认值的语义一律是**静默降级**： + +| 方法 | 位置 | 默认行为 | +|---|---|---| +| `sanitizeJdbcUrl` | `:79-81` |

+ +iceberg 与 paimon 的插件把 `hadoop-common`、`fe-kerberos`（iceberg 还有 `iceberg-aws`）按 child-first 打进插件包，所以插件内部任何**按类名反射**的加载（默认用线程上下文类加载器）如果跑在引擎线程的默认加载器下，就会拿到 fe-core 那一份副本，与插件自己那一份互相 `ClassCastException`。为此两个连接器各有一个装饰器，把 `executeAuthenticated` 包起来，在任务执行期间把线程上下文类加载器钉到插件加载器，Kerberos 目录还额外在插件侧的 `doAs` 里跑： + +- `fe/fe-connector/fe-connector-iceberg/src/main/java/org/apache/doris/connector/iceberg/TcclPinningConnectorContext.java:74`（`executeAuthenticated` 在 `:98-114`，其余「纯转发」段落在 `:116-210`） +- `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/TcclPinningConnectorContext.java:63`（`executeAuthenticated` 在 `:76-92`，纯转发段落在 `:94-179`） + +装饰器在连接器构造时套一次，之后整个连接器只看得见包装后的上下文：`IcebergConnector.java:225`、`PaimonConnector.java:153`。 + +### 2.3 实测的转发缺口 + +按符号逐个比对（已在 HEAD 上核实）： + +| 包装类 | 覆写的 `ConnectorContext` 方法数 | 漏掉的方法 | +|---|---|---| +| iceberg | 18 / 19 | `getFileSystem(ConnectorSession)` | +| paimon | 17 / 19 | `getFileSystem(ConnectorSession)`、`newStorageUriNormalizer(Map)` | + +漏掉的方法会落到接口默认实现上：连接器调 `context.getFileSystem(session)` 拿到的是 `null`，而不是引擎那个按 catalog 缓存的文件系统。 + +### 2.4 hive 已经在真的用引擎文件系统 + +hive 连接器（它**没有**这种包装类，直接持有引擎注入的上下文）已经有 6 个直接调用点：`HiveScanPlanProvider.java:153`、`:157`、`:258`，`HiveConnectorMetadata.java:910`、`:942`，`HiveConnectorTransaction.java:756`；其中 transaction 那一处是私有 helper，内部再扩散到约 19 个读写目录的位置。这个 helper 对 `null` 是失败退出的： + +```java +// HiveConnectorTransaction.java:755-761 +private FileSystem getFileSystem() { + FileSystem engineFs = context.getFileSystem(session); + if (engineFs == null) { + throw new DorisConnectorException("No engine FileSystem available for hive write transaction " + + transactionId + " (catalog has no storage properties)"); + } +``` + +注意这句报错文案把原因归给了「目录没有存储属性」。 + +### 2.5 同一类接口存在三套政策 + +- `ConnectorContext`（引擎实现）：2 抽象 + 17 默认； +- `ConnectorValidationContext`（同样是引擎实现，`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorValidationContext.java`）：`:34`、`:37`、`:40`、`:50`、`:59`、`:73` 共 6 个方法，**全抽象**； +- `ConnectorProvider`（连接器实现，`fe-connector-spi/.../ConnectorProvider.java`）：`:46`、`:64` 抽象，`:52`、`:74`、`:79`、`:84`、`:93` 默认（方向正确）。 + +公共模块里没有任何一处成文规则说明这三套差异从何而来。（把规则写下来是任务 07 的事，本任务只做机理修复。） + +## 三、为什么这是个问题 + +**先把严重性说准**：今天 iceberg 与 paimon 都还没有调用 `context.getFileSystem(...)`（全仓库检索，只有 hive 在用），paimon 也还在用逐次的 `normalizeStorageUri(rawUri, token)`（`PaimonScanPlanProvider.java:735`）而没有用批量归一器。所以这**不是一个当前用户能观测到的错误**，是潜伏缺陷。这一点必须写清楚，避免下一位实施者按「线上故障」去找复现。 + +它真正的问题有三层： + +1. **一旦被使用就是难查的故障。** iceberg/paimon 哪天开始用引擎文件系统（这是本项目明确的方向：连接器不再自带 Hadoop `FileSystem`，由引擎按 scheme 路由），拿到的是 `null`。如果照 hive 的写法做 `null` 检查，用户看到的报错会是「catalog has no storage properties」——**指向一个完全无关的原因**，而目录的存储属性其实是好的；如果没做检查，就是一个空指针。 +2. **paimon 少的那个批量归一器是静默性能回退。** 行为仍然正确，但每个数据文件都会重新推导一遍存储配置（`StorageProperties.createAll` + 一次 hadoop config 构建），把「每次扫描一次」变回「每文件一次」，没有任何日志。 +3. **机理本身是事故源，而且会复发。** 这两个类存在的唯一理由就是钉类加载器。而它们采用「实现接口 + 手抄每个方法」的写法，于是**每往 `ConnectorContext` 加一个带默认实现的方法，这两个类都会默认漏掉那一次转发**，编译器一句话都不会说。本项目已经反复踩过类加载器分裂事故（扫描线程、写/DDL 引擎线程、iceberg 内部 manifest 写线程池、HMS 客户端创建点，四个位置各修过一次），这是同一类事故的下一个入口。 + +## 四、用一个最小例子说明 + +### 例子一：连接器写了一行取文件系统的代码 + +假设 paimon 连接器要清理一个写失败留下的临时目录，于是照 hive 的写法写： + +```java +FileSystem fs = context.getFileSystem(session); // 连接器代码，编译通过 +fs.delete(Location.of(tmpPath), true); +``` + +| 连接器作者写了什么 | 今天实际发生什么 | 应该发生什么 | +|---|---|---| +| `context.getFileSystem(session)` | 调用落到包装类上；包装类没有覆写这个方法 → 走接口默认实现 → **返回 `null`** → 下一行空指针 | 转发到引擎上下文 → 拿到该 catalog 的引擎文件系统 | +| 编译期 | 无任何提示 | 无提示（这也是问题：所以要靠单测兜住） | +| 排错时看到的线索 | 空指针，或者（若模仿 hive 加了检查）「catalog has no storage properties」——把作者引向去查目录属性 | 不该发生 | + +### 例子二：明天给引擎上下文加一个新方法 + +假设某个新需求要在引擎上下文上加一个 `getTableLocationResolver()`，它内部会进插件代码： + +```java +// 有人在 ConnectorContext 里加： +default TableLocationResolver getTableLocationResolver() { return TableLocationResolver.NOOP; } +``` + +作者改了 `DefaultConnectorContext`，跑通了 hive 的端到端用例（hive 不走包装类），提交。**iceberg 与 paimon 从此静默拿到 `NOOP`，且这次调用不再有类加载器钉桩。** 这就是本任务要堵的那条缝：不是这一次谁忘了，而是这个写法保证了以后每次都会忘。 + +## 五、解决方案 + +### 5.1 目标状态 + +在公共模块 `fe-connector-spi` 提供一个转发基类，两个钉桩包装类改为**继承它、只覆写真正需要特殊处理的方法**；再用一个反射驱动的单测钉住「基类必须覆写接口的每一个方法，且每次调用都必须原样到达被包装的上下文」。 + +签名草案（`org.apache.doris.connector.spi.ForwardingConnectorContext`）： + +```java +/** + * 装饰 ConnectorContext 的基类：逐方法转发给被包装的上下文。 + * 需要在某个方法上做额外处理（例如把线程上下文类加载器钉到插件加载器）的装饰器， + * 只覆写那个方法，其余方法由本类保证转发。 + * + * 新增 ConnectorContext 方法时必须同时在本类补一个转发， + * ForwardingConnectorContextTest 会强制这件事。 + * 如果新方法会进入插件代码，钉桩子类还必须覆写它并加钉桩。 + */ +public abstract class ForwardingConnectorContext implements ConnectorContext { + + private final ConnectorContext delegate; + + protected ForwardingConnectorContext(ConnectorContext delegate) { + this.delegate = Objects.requireNonNull(delegate, "delegate"); + } + + /** 被包装的原始引擎上下文（子类需要绕过自身装饰时用它）。 */ + protected final ConnectorContext delegate() { + return delegate; + } + + @Override public String getCatalogName() { return delegate.getCatalogName(); } + // …… 其余 18 个方法逐一转发，一个不漏 …… +} +``` + +改完之后，两个包装类的正文只剩：构造函数（多传一个插件加载器与认证器）、`executeAuthenticated` 的钉桩实现、iceberg 那个包私有的 `getPluginAuthenticator()`（`:94-96`，写路径要拿它把认证器带进 FileIO，必须保留）。 + +**为什么选转发基类，而不是把方法改成抽象**： + +| 方案 | 代价 | 是否根治 | +|---|---|---| +| 转发基类（推荐） | 新增 1 个公共类；两个包装类各减约 85 行 | 是。补一处即两个包装类同时受益；配合单测，新增方法时会被强制处理 | +| 把「引擎必须履约」的方法（地址消毒、认证包装、取文件系统）改成抽象 | 全仓库有 25 个 `ConnectorContext` 实现（8 个具名 + 17 个匿名），其中 22 个是测试替身（17 个匿名全在测试源，具名测试替身 5 个），只有 3 个是生产实现（`DefaultConnectorContext` 与两个钉桩包装类）；改抽象要逐个补空实现，`getFileSystem` 变抽象还会逼每个离线测试替身去编造一个文件系统 | **否**。包装类仍然要为每个新方法手抄一次转发，钉桩照旧会漏；而且以后每加一个抽象方法就一次性打断 25 个实现 | + +所以推荐第一条路；同时**不**顺手改抽象/默认的划分（那属于任务 07 的规则梳理，本任务只在基类的注释里写清「新增方法必须补转发」）。 + +残留风险要写在基类注释里：基类只保证「不丢转发」，不保证「不丢钉桩」。如果新方法会进入插件代码，钉桩子类必须自己覆写并加钉桩——单测失败时的提示语要把这句话直接写出来，让改接口的人当场做这个判断。 + +### 5.2 改动清单 + +| 文件 |

+顺序建议：先加基类与基类单测（此时两个包装类不动，编译通过），再逐个迁移包装类；每一步都能独立编译验证。 + +### 5.3 明确不要顺手做的事 + +- **不要把 `ConnectorContext` 的任何默认方法改成抽象。** 理由见 5.1 的对照表（25 个实现、其中 22 个测试替身）。抽象/默认政策的统一是任务 07 的范围。 +- **不要给 hive 连接器加这种包装类。** hive 直接用引擎注入的上下文，本来就没有这个缺口；plain-hive 的类加载器钉桩在别的位置（HMS 客户端创建点与 `HiveConf` 构造点）已经解决，不要在这里重做一遍。 +- **不要顺手给基类的转发方法加钉桩。** 现有两个包装类明确写了哪些方法不需要钉桩（存储地址归一化、后端连通性探测完全跑在引擎侧）。无差别加钉桩会改变现有行为并带来无谓开销。 +- **不要动 `ConnectorSession` 的默认值问题**（`getStatementScope` 默认不记忆等）。那是同类问题的另一个接口，属于另一条任务，本任务不扩。 +- **不要写 shell / 正则门禁去校验「包装类是否覆写齐全」。** 本仓库已有结论：这类门禁只适合存在性与前缀类不变量，要理解 Java 语义就等于在 shell 里写解析器，误报比漏报更毒。这里用运行时单测。 +- **不要顺手删 `getMetaInvalidator`**。删除推模型失效接口是任务 14，它同样要改这两个包装类；本任务先做完，任务 14 届时只需在基类删一个转发方法。 +- 不要改 `fe-core`：本任务全部改动落在公共模块与两个插件里，符合「fe-core 只出不进」。 + +## 六、怎么验证 + +### 6.1 基类单测：反射 + 动态代理，逐方法断言「原样到达」 + +`ForwardingConnectorContextTest` 的做法（放在 `fe-connector-spi`，与既有的 `ConnectorContextTest` 同目录；该模块已有 `junit-jupiter` 依赖，动态代理用 JDK 自带的 `java.lang.reflect.Proxy`，无需新依赖）： + +1. 用 `Proxy.newProxyInstance` 造一个记录型 `ConnectorContext`，记录每次被调用的 `Method`（名字 + 参数类型）与实参，并返回该返回类型的一个可区分的取值（例如文件系统返回一个 `Proxy` 出来的非 `null` 实例、字符串返回带标记的串）。 +2. 造一个空的匿名子类 `new ForwardingConnectorContext(recording) {}`。 +3. 反射枚举 `ConnectorContext.class.getMethods()`，对每个方法用按类型编造的实参调用一次（`ConnectorSession` 传 `null`，接口文档允许；`Callable` 传一个返回标记值的任务）。 +4. 断言：**每次调用都在记录器上留下了同一个方法**（按名字 + 参数类型精确比对，不能只比名字），且实参与返回值原样穿过。 + +这个测法为什么能真正抓住缺陷（逐一对应今天的两个缺口）： + +- 少覆写 `getFileSystem` → 走接口默认 → 记录器上没有任何记录 → **失败**； +- 少覆写 `newStorageUriNormalizer` → 接口默认返回一个 lambda、当场不碰被包装对象 → 记录器上没有记录 → **失败**； +- 少覆写 `normalizeStorageUri(String, Map)` → 接口默认转调单参版本 → 记录器上记录的是**单参**方法 → 因为按参数类型精确比对，**失败**（这正是「只比方法名会漏」的那种情况）； +- 少覆写 `getBackendFileType` / `testBackendStorageConnectivity` / `cleanupEmptyManagedLocation` → 默认实现自己算或什么都不做 → 无记录 → **失败**。 + +**变异验证（必须做）**：从基类里手工删掉任意一个转发方法，跑该测试，确认它报错并且报错信息指出了是哪个方法；恢复。至少对 `getFileSystem` 和 `normalizeStorageUri(String, Map)` 各做一次。 + +### 6.2 两个连接器的包装类单测 + +保留现有断言不变（这是行为不变的证据）：钉桩生效、任务抛异常时恢复调用方加载器、非 Kerberos 走被包装上下文的认证、Kerberos 走插件侧 `doAs` 且不再调被包装上下文的认证、`createSiblingConnector` 转发给原始上下文。各补一条： + +- iceberg：`ctx.getFileSystem(null)` 返回的对象与记录型上下文给出的同一个（今天返回 `null`，改前应先确认这条新断言在旧代码上是失败的）。 +- paimon：同上，并额外断言 `ctx.newStorageUriNormalizer(token)` 返回的是被包装上下文给出的那个归一器实例（不是接口默认的 lambda）。 + +### 6.3 编译与测试命令 + +```bash +# 最强单一信号：全反应堆含测试源编译（禁止跳过测试编译） +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T1C test-compile + +# 跑本任务相关单测（必须禁用 build cache，否则 surefire 会被静默跳过、BUILD SUCCESS 是空的） +mvn -f

+注意 checkstyle 会扫测试源，新文件要按仓库现有风格写（许可头、import 顺序）。 + +### 6.4 端到端回归 + +本任务不改变任何现有运行时行为（补的两个方法今天无调用点，其余方法转发路径逐字等价），**不需要新增端到端用例**。既有的端到端把关点是 iceberg 的 Kerberos 回归套件——它验证 `executeAuthenticated` 的钉桩与单一认证方语义没被这次继承结构调整改坏；paimon 没有活的 Kerberos 套件，依靠上面的单测与 iceberg 套件同机理覆盖（这一点两个包装类的现有类注释已经写明）。 + +## 七、风险与回退 + +- **风险：继承结构调整改坏认证语义。** `executeAuthenticated` 是唯一带逻辑的方法，迁移时只把 `delegate` 字段访问换成 `delegate()`，其余一字不改；两个连接器现有的四条认证/钉桩断言全部保留，任何行为偏移都会被它们抓到。 +- **风险：类加载器层面的问题。** 基类放在 `org.apache.doris.connector.spi`，落在 `ConnectorPluginManager.java:65` 声明的 parent-first 前缀内（`org.apache.doris.connector.`），与 `ConnectorContext` 本身同一份副本，插件里的子类继承它不产生第二份类。这与两个包装类今天实现 `ConnectorContext` 的加载路径完全一致。 +- **风险：给公共模块增加了一个公共类。** 这个类是「引擎实现、连接器消费」这一侧的官方装饰基类，与该模块的定位一致，且它减少的是「以后每次改接口要动的地方」，方向与本条工作线的目标（新增连接器不必改公共模块）一致。 +- **回退**：改动自包含在 1 个新增类 + 1 个新增测试 + 2 个插件文件里，直接 revert 这一个提交即可，无数据格式、无持久化、无有线格式牵连。 + +## 八、相关背景 + +- 调研报告 `../audit-report.md`： + - **附录 D.2** —— 引擎侧接口默认值全是静默降级、两个包装类漏转发：本任务的直接来源，含三套政策的对比； + - 第 3.2 节「五个结构性问题」总表里编号为六的那一行 —— 同一条问题的一句话版； + - **附录 D.3** —— 会话接口同病、有默认值会静默关掉性能优化：同一类问题在 `ConnectorSession` 上的表现（`getStatementScope` 默认不记忆会静默关掉按语句去重）。本任务**不**处理它，但下一位实施者应知道它是同一机理的另一处。 +- 同一任务空间：任务 07（把两个公共模块的设计规则写下来，包括抽象/默认的政策）、任务 14（删除推模型失效接口，同样要改这两个包装类，**排在本任务之后**）。 +-

+`api/pushdown`、`api/scan`、`api/write`），没有任何一份文档说明这些包的分工与设计约束。整个 +`fe-connector` 目录下只有两份包级文档：`fe-connector-cache` 一份、`fe-connector-spi` 一份。 + +**（b）`fe-connector-spi` 那份包级文档只说了一句话，而且不完整。** +`fe/fe-connector/fe-connector-spi/src/main/java/org/apache/doris/connector/spi/package-info.java:18-28` 全文只讲： +本包定义连接器必须履行的 SPI 契约，主入口是 `ConnectorProvider`，连接器实现「应当依赖本模块 +（`fe-connector-spi`）并在 `META-INF/services` 里注册」。它既没说连接器同时也要用到 +`fe-connector-api`（实际上 `fe-connector-spi/pom.xml:43-47` 声明了对 `fe-connector-api` 的依赖，所以是传递带进来的， +但读文档的人看不出来），也没有任何一句说明「什么该放 api、什么该放 spi」。 + +**（c）能力声明今天有三种形态并存，规则没写下来。** 三层形态本身在代码里是存在的： + +- `Connector` 上的取得器，缺席返回 `null`：`Connector.java:66`（`getScanPlanProvider`）、`:93` + （`getWritePlanProvider`）、`:192`（`getProcedureOps`）； +- 各 provider 自己的开关：例如 `ConnectorWritePlanProvider` 上的 `supportsWriteBranch()` / + `requiresParallelWrite()` / `requiresFullSchemaWriteOrder()` / `requiresPartitionLocalSort()` / + `requiresPartitionHashWrite()` / `requiresMaterializeStaticPartitionValues()`； +- 能力枚举 `ConnectorCapability`（`ConnectorCapability.java:31-182`，共 13 个常量）。 + +但**哪一层放什么，只有 `ConnectorCapability` 的类文档写了一条边界**（`:20-29`：写操作与 sink 特性不进枚举、 +放 provider）。这条边界看上去有一处例外：建表期的 ORDER BY 子句门 `SUPPORTS_SORT_ORDER` 在枚举里 +（`:165`），写路径的行序 `requiresFullSchemaWriteOrder` 在 provider 上，两者都能被笼统地归为「写相关能力」。 +**但这不是疏漏，代码里已经写明了区分理由**：`SUPPORTS_SORT_ORDER` 的 javadoc（`ConnectorCapability.java:153-163`） +明确写了它是「建表 DDL 子句门」（`CREATE TABLE ... ORDER BY` 这个子句是否被接受，引擎在静态规划期就要判定， +此时还拿不到写计划提供者），并显式声明它**不同于**运行期 sink 特性 +`ConnectorWritePlanProvider.requiresFullSchemaWriteOrder()`（管的是写路径上行怎么排序）。 +所以规则文档要做的是**把这条既有理由收录成判据**（「DDL 子句门进枚举、运行期 sink 特性进 provider」）， +**不要**把它当成需要被纠正的不一致去搬动 `SUPPORTS_SORT_ORDER`。 + +**（d）按表能力走的是逗号分隔字符串，且只对 13 个能力中的 5 个生效。** +`ConnectorTableSchema.java:98` 定义键 `__internal.connector.per-table-capabilities`；引擎唯一读它的地方是 +`PluginDrivenExternalTable.java:302` 的私有方法 `hasScanCapability`，调用方 5 处 +（`:239`、`:251`、`:264`、`:276`、`:289`）。其余 8 个能力只读连接器级集合。 + +**（e）异常契约完全缺失。** `DorisConnectorException.java` 全文只有一个 `RuntimeException` 子类和两个构造器， +类文档一句「Base runtime exception for all connector-related errors.」，没有任何分类、没有任何该抛/不该抛的判据。 +连接器实际混用多个异常族（在 `fe/fe-connector` 下 grep `throw new`：`DorisConnectorException` 395 处、 +`UnsupportedOperationException` 330 处、`IllegalArgumentException` 111 处、`RuntimeException` 102 处、 +`IllegalStateException` 30 处），而引擎侧只翻译 `DorisConnectorException` 这一族 +（`fe-core` 里 `catch (DorisConnectorException` 共 32 处，典型如 +`PluginDrivenExternalCatalog.java:816` 把它包成 `DdlException`）。其余族一路冒泡成 FE 内部错误。 + +**（f）thrift 在两个模块上是两套相反的规则。** `fe-connector-api` 直接用 thrift 生成类，完整清单（实测）： + +| 位置 | thrift 类型 | +|---|---| +| `api/scan/ConnectorScanPlanProvider.java:24-26` | `TFileCompressType`、`TFileScanRangeParams`、`TTableFormatFileDesc` | +| `api/scan/ConnectorScanRange.java:20-21` | `TFileRangeDesc`、`TTableFormatFileDesc` | +| `api/handle/ConnectorWriteHandle.java:21` | `TSortInfo` | +| `api/write/ConnectorSinkPlan.java:20` | `TDataSink` | +| `api/ConnectorTableOps.java:464` | `org.apache.doris.thrift.TTableDescriptor`（**内联全限定名**，不是 import） | + +（另有一处只出现在注释里：`api/write/ConnectorWritePlanProvider.java:33` 的 javadoc 提到 `TDataSink`， +不构成依赖。`fe-thrift` 在 `fe-connector-api/pom.xml` 里是 `provided` 作用域、不传递。） +而 `fe-connector-spi` 刻意绕开 thrift：`ConnectorContext.java:255` 的 `getBackendFileType` 返回**枚举名字符串**、 +`:291` 的 `getBrokerAddresses` 返回中立的 `ConnectorBrokerAddress`、`:337` 的 +`testBackendStorageConnectivity(int storageBackendTypeValue, ...)` 把一个 thrift 枚举的**整数值**当参数传。 + +**（g）生命周期与线程模型一字未写。** +`Connector.java:45` 的 `getMetadata` 全部文档就是「Returns the metadata interface for the given session.」。 +实际契约在引擎侧：`PluginDrivenMetadata.java:28-42` 明确写了「一条语句每个 catalog 恰好用一个 +`ConnectorMetadata` 实例，语句结束时确定性关闭」，而且这是 fe-core 里唯一允许直接调 `getMetadata` 的地方。 +`ConnectorMetadata.java:233` 的 `close()` 默认空实现，无任何幂等/线程要求。 +统计接口 `ConnectorStatisticsOps.java:30` 的类文档只有一句「Operations for retrieving table-level statistics +from a connector.」——**没写它会在引擎的后台统计线程上被调用，也没写引擎不会钉线程上下文类加载器**。 +证据：`PluginDrivenExternalTable.java:1026` 的 `getColumnStatistic` 与 `:1061` 的 `getChunkSizes` 全程不钉 +类加载器，`:1057` 的注释甚至明写「No TCCL pin here; the hive `listFileSizes` impl pins internally」；对应的连接器侧 +`HiveConnectorMetadata.java:939-954` 自己动手 `setContextClassLoader` 兜的正是这件事。 + +**（h）两处模块描述已经与代码不符。** +`fe-connector-spi/pom.xml:38` 写自己「包含 `ConnectorProvider`、`ConnectorContext` 和 `ConnectorTypeMapper`」—— +`ConnectorTypeMapper` 这个类**全仓不存在**（Java 源里零命中；命中只有这行描述本身、调研报告引用它的那一行， +以及构建生成物 `fe/fe-connector/fe-connector-spi/.flattened-pom.xml:29` 里这行描述的副本—— +第六节自检那条带 `--include='*.xml'` 的 grep 会命中生成物，不要误判成「没删干净」）。 +`fe-connector-api/pom.xml:35-38` 自称「Consumer-facing API」（面向消费方的 API），而它实际装的是**连接器要实现**的 +95 个接口与值对象。 + +--- + +## 三、为什么这是个问题 + +**（1）没有规则，新增连接器的第一个动作就是猜。** 想声明一项能力，作者要在 `Connector`（取得器返回 null）、 +provider 的 `supportsXxx()`、`ConnectorCapability` 枚举、按表能力字符串这四种形态里选一个，而四种形态并存的 +理由没有任何地方写。选错了不会有编译错误，也不会有测试失败——只会「实现了但没生效」，然后花半天排查。 + +**（2）文档写在错的地方比没写更贵。** 现在唯一写下来的两句都不准：`fe-connector-spi` 的包文档说自己是 +「连接器实现必须履行的契约」（实际上连接器要实现的东西 95% 在 `fe-connector-api`），`fe-connector-api` 的 pom +说自己是「面向消费方」（实际相反）。照这两句去理解模块分工，会得到完全反的结论。 + +**（3）异常没有分类，用户看到的报错就没有分层。** 连接器抛 `IllegalArgumentException` 时引擎不翻译， +用户拿到的是一条内部异常；抛 `DorisConnectorException` 才会被翻译成 `DdlException` 这类可读错误。 +今天这个区别没写在任何契约里，等于让「用户能不能看懂报错」取决于连接器作者随手选了哪个异常类。 + +**（4）线程与类加载器这条契约「踩了就炸」，而它一字未提。** 本项目已知的高危坑就是跨插件类加载器的按名反射： +统计方法跑在引擎后台线程上、引擎不钉线程上下文类加载器，连接器如果不自己钉，捆绑库按名反射会撞上 fe-core 里的 +重复副本，表现为 `ClassCastException` / `NoClassDefFoundError`，而且是偶发的（只在后台 ANALYZE 触发时炸）。 +hive 连接器是自己摸出来后补的救；下一个连接器作者没有任何线索知道要补。 + +**（5）后面每一批整治都需要判据。** 第 10 号（拆 `ConnectorTableOps`）与第 17 号（按表能力类型化 + 删镜像方法） +都要回答「这个开关该落在哪一层」。规则不先落地，那两批就是逐项拍脑袋。 + +--- + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 X，只想做一件很小的事：**告诉引擎「我这个连接器支持写入分支（write branch）」**。 + +| 我想做什么 | 今天我实际会遇到什么 | 规则写下来之后应该是什么 | +|---|---|---| +| 找一份文档看规则 | `fe-connector-api` 没有包级文档；`fe-connector-spi` 的包级文档只说「注册 `ConnectorProvider`」 | `fe-connector-api/package-info.java` 第一段就说明能力声明分三层，以及每层的判据 | +| 挑一个地方声明 | 看到 `Connector.supportsWriteBranch()`（`Connector.java:132`）和 `ConnectorWritePlanProvider.supportsWriteBranch()` 两个同名方法，不知道该覆写哪个 | 规则明确：**覆写 provider 上的那个**；`Connector` 上的同名方法是引擎用的空安全读取口，连接器不得覆写 | +| 覆写 `Connector.supportsWriteBranch()` | 能编译、能运行，但如果同时没改 provider，两个答案就分叉；**没有任何测试会失败** | 规则把「唯一真源在 provider」写成契约，第 17 号任务再把这些方法改成语言层面无法覆写的形式 | + +再举第二个更小的：我的连接器发现远端表不存在，该抛什么异常？ + +``` +throw new IllegalArgumentException("table not found: " + name); // 今天：引擎不翻译，用户看到内部异常栈 +throw new DorisConnectorException("table not found: " + name); // 今天：引擎翻译成 DdlException，用户看到可读错误 +``` + +两行都能编译、都能跑，差别只在用户看到的报错长什么样，而**没有任何文档告诉作者该选哪一行**。 + +--- + +## 五、解决方案 + +### 5.1 目标状态 + +新增 `fe-connector-api` 的包级说明，改写 `fe-connector-spi` 的包级说明，两份互相引用。 +**文档正文用英文**（与仓库既有 javadoc 一致，`fe-connector-cache/package-info.java` 是可照抄的格式模板： +ASF 头 + 一段 `

    ` 段落，不写任何 import）。下面用中文写清每条规则要表达什么。 + +**规则一：能力声明分三层，且只有三层。** + +1. **「整块子系统有没有」** → `Connector` 上的 provider / ops 取得器，缺席返回 `null` + （`getScanPlanProvider` / `getWritePlanProvider` / `getProcedureOps` / `getEventSource`）。 + 保持 `null` 而不是改 `Optional`：引擎已按 `null` 判定，换掉是纯变更噪音。 +2. **「某块子系统内部的开关」** → 该 provider 自己的 `supportsXxx()` / `requiresXxx()`，一律默认 `false` + （opt-in），引擎必须先拿到 provider 再问。**唯一真源在 provider**。 + `Connector` 上现存的 11 个同名方法（`Connector.java:115/126/132/138/144/150/156/162/168/177/183`） + 是引擎侧的空安全读取口（方法体一律「取 provider，为空返 false，否则转发」）， + **连接器不得覆写它们**——今天 0 个连接器覆写（已核实：三个连接器只在各自的 + `*WritePlanProvider` 上覆写），规则要把这件事从「运气」变成「契约」。 +3. **「引擎拿不到 provider 也必须问的静态规划开关」** → `ConnectorCapability` 枚举，且一律按 + 「连接器级 ∪ 按表级」加法解析。凡是与某个 provider 一一对应的开关不得进枚举。 + 现成的判据范例（照抄 `ConnectorCapability.java:153-163` 已写明的区分，不要改设计）： + 建表 DDL 子句门 `SUPPORTS_SORT_ORDER` 留在枚举里，因为引擎要在静态规划期判定 + `CREATE TABLE ... ORDER BY` 这个子句是否被接受，此时还拿不到写计划提供者； + 而运行期的行序 sink 特性 `requiresFullSchemaWriteOrder()` 在 provider 上。 + 两者名字都沾「写」，但一个管「DDL 子句收不收」、一个管「写路径上行怎么排」，分层是对的。 +4. **「值缺失」用 `Optional`，「整块子系统缺席」用 `null`** —— 这两者的区分写进规则，避免被当成两套竞争机制。 + +同时写清现状偏差：按表细化今天只对 5 个能力生效（`hasScanCapability` 的 5 个调用方）， +接口承诺的是 13 个；第 17 号任务负责补齐，在那之前**不要假设自己新加的枚举常量能按表细化**。 + +**规则二：异常分四类，并给出 fail loud 与静默降级的判据。** + +- 连接器一律抛 `DorisConnectorException` 或其子类（这是引擎唯一会翻译的一族，32 处 `catch`）。 +- 四类：**用户错误**（SQL 或参数不合法 / 对象不存在）、**配置错误**（catalog 属性缺失或矛盾）、 + **远端不可用**（元数据服务或存储超时、拒绝、鉴权失败）、**内部错误**（连接器自身的不变量被破坏）。 +- 判据：**凡是用户显式发起、结果会被用户直接看到的操作，一律 fail loud**（DDL、写入、 + `ANALYZE ... WITH SAMPLE` 这类显式统计采样）；**凡是引擎为优化而做的尽力而为探测，失败必须静默降级** + （返回空 / 返回默认值，并记日志），因为它们不该让查询失败。 +- 用这条判据顺带把两处矛盾定性（具体修文档是第 8 号任务的事，本任务只写规则）： + `ConnectorStatisticsOps.java:96` 的 `listFileSizes` 文档写「出错必须返回空、不得抛异常」， + 唯一实现 `HiveConnectorMetadata.java:931-955` 故意抛出且有单测锁死——按判据**实现是对的、文档是错的**， + 显式采样吞异常会让采样因子静默塌成 1.0、产出错误统计。 + `ConnectorMetadata.java:141-143` 的 `resolveTimeTravel` 文档写「不支持的规格返回空」， + iceberg 与 hudi 对不支持的规格抛 `DorisConnectorException`（`IcebergConnectorMetadata.java:2038` 附近、 + `HudiConnectorMetadata.java:488` 附近），paimon 一律返回空——按判据抛出是对的（用户显式写了 + `FOR VERSION AS OF`，静默当作没写会给出错的结果集），应把文档改成据实。 + +**规则三：thrift 只允许出现在面向 BE 的协议边界上。** + +- 承认结构性事实：BE 是 C++、没有插件机制，面向 BE 的负载必须走 thrift。 +- 把 §二（f）的完整清单原样写进文档（5 个位置），并明确：**不再新增以 thrift 类型为入参的方法**； + 新增的返回值若必须携带 BE 负载，只允许复用清单里已有的类型。 +- 把 `fe-connector-spi` 侧那三处「为了 thrift-free 而做的字符串/整数化」的现状与理由记下来， + 并注明这条 thrift-free 承诺**并未真正兑现**（`spi` 依赖 `api`，`api` 依赖 `fe-thrift`）， + 所以它是一处局部约定而不是模块级不变量。是否统一留待后续，不在本任务范围。 + +**规则四：`api` 与 `spi` 的划分以「谁实现」为准，并写明现状偏差。** + +- 规则：**连接器实现、引擎消费** 的类型放 `fe-connector-api`；**引擎实现、连接器消费** 的类型 + 以及服务发现入口放 `fe-connector-spi`。依赖方向 `spi → api` 单向（已核实：`api` 里 + `org.apache.doris.connector.spi` 零命中）。 +- 写明偏差：`ConnectorSession`、`ConnectorHttpSecurityHook`、`ConnectorValidationContext` 三个「引擎实现」的类型 + 今天在 `fe-connector-api` 里；这属于已知偏差，**不在本任务里搬**（搬动会波及全部连接器的 import）。 +- 写明**两个模块名整体是反着的**：按业界惯例（也是 Trino 的用法）「连接器要实现的东西」叫 SPI、 + 「连接器要消费的引擎服务」叫 API，而这里 `fe-connector-api`（95 个文件）装的是连接器要实现的， + `fe-connector-spi`（5 个文件）装的是连接器要消费的。**明确不改模块名**（改名波及所有连接器的 pom + 与 fe-core 依赖，收益只是命名），只把这件事写清楚，让读代码的人第一眼就知道名字别当真。 +- 顺手修两处 pom 描述：删掉 `fe-connector-spi/pom.xml:38` 里全仓不存在的 `ConnectorTypeMapper`； + 把 `fe-connector-api/pom.xml:35-38` 的「Consumer-facing API」改成据实（连接器实现、引擎消费）。 + +**规则五：生命周期与线程模型。** + +- `Connector` 每个 catalog 一个实例（`Connector.java:36-41` 的类文档已写，保持）。 +- `getMetadata` 返回的实例：**每条语句每个 catalog 恰好一个**，由引擎在语句结束时关闭； + `close()` **必须幂等**；**单个实例不得跨线程共享**。文档里指向引擎侧的唯一入口 + `PluginDrivenMetadata`（它已经把这个契约写清了，`PluginDrivenMetadata.java:28-42`）， + 并在 `ConnectorMetadata.close()`（`:233`）上交叉写一句。 +- **统计接口（`ConnectorStatisticsOps`

每条规则后面附一句「现状偏差」，不把目标状态写成既成事实；把「这条规则由第几号任务兑现」写清， + 读者不会误以为今天就已经生效。 +- **第二个风险是与第 8 号任务撞注释。** 第 8 号要成批修陈旧的接口文档，两个任务都会碰 + `ConnectorStatisticsOps` / `ConnectorMetadata` 的 javadoc。缓解：本任务只加「线程与生命周期」段落， + **不修 `listFileSizes` / `resolveTimeTravel` 的文案**，文案留给第 8 号；若两者并行，先合本任务。 +- **回退**：单个提交 revert 即可，零运行时影响（改动全是注释与 pom 描述）。 + +--- + +## 八、相关背景 + +-

`fe/fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenMetadata.java:28-42` + +--- + +## 九、施工后订正（2026-07-25 落地时实测，以本节为准） + +本节记录动手前复核发现的、与 §二 不符的事实。**§二 里被订正的说法不要再引用。** + +1. **异常族：引擎翻译的是两族，不是一族。** 元数据 / DDL / DML / 扫描规划路径认 `DorisConnectorException`（32 处 catch）；**属性校验路径只认 `IllegalArgumentException`**——`PluginDrivenExternalCatalog.checkProperties` 捕获它并把 message 重抛为 `DdlException`，那里它是唯一会被解包的类型，5 个连接器共 13 处抛点依赖它，`HiveConnectorProvider` 的注释已写明「这是唯一…」。规则文档已按「分路径」写。**若按 §二 那句「只翻译一族」去统一异常，会把建目录的报错退化成内部异常。** +2. **异常族计数的口径错了。** §二(e) 的五个数字是 main+test 混计。生产（`src/main`）真实数字：`DorisConnectorException` 395、`UnsupportedOperationException` **50**（不是 330——那 330 里 280 处是测试替身的未实现桩）、`IllegalArgumentException` 109、`RuntimeException` 90、`IllegalStateException` 23。也就是说生产代码已经约 74% 集中在 `DorisConnectorException` 上，「混用严重」这个论据要按生产口径收窄。 +3. **异常族已经有一个子类，且是承重的。** `HiveDirectoryListingException extends DorisConnectorException`，作用是让扫描路径只 catch「可跳过的列目录失败」，而普通 `DorisConnectorException` 仍然失败整个查询。规则文档把它作为**已获批准的扩展范式**引用，而不是另发明分类。 +4. **缺席取得器是 4 个不是 3 个**：漏了 `getEventSource`（§5.1 规则一里本来就列了 4 个，是 §二(c) 少写一个）。 +5. **「能力开关一律默认 false」在今天不成立**：`ConnectorPushdownOps.supportsCastPredicatePushdown` 默认 `true`；且 `supportsXxx` 形态还出现在 `ConnectorScanPlanProvider`（3 个）与三个非 provider 接口上。规则文档写成「目标 + 唯一既有例外」。 +6. **统计方法的线程模型比 §二(g) 写的更宽**：不是「后台统计线程」单数，而是三个不同的守护线程池（列统计缓存加载 `STATS_FETCH`、采样 ANALYZE 的分析作业执行器、外部行数刷新执行器），且**没有一条路径钉类加载器**；带快照的 `getTableStatistics` 重载只在查询线程上。文档按「多个后台池 + 把所有方法都当可后台调用」写。 +7. **`fe-connector-api/pom.xml` 的 `` 跨 :35-43**（不是 :35-38），后面还有一段关于 fe-thrift provided 作用域的说明，改写时要保留。 +8. **`package-info.java` 里不能写 import 的理由是错的**：`UnusedImports` 的 `processJavadoc` 在 checkstyle 9.3 下默认**开启**，只在 javadoc 里用到的 import 不会被判未使用。实际约束是另一条：**全仓没有任何 javadoc 校验绑定**（8 个 pom 里的 javadoc 插件全是 `skip=true`），所以 `{@link}` 写错既不会挂构建也不会告警，只能靠人核。另外连接器路径的 javadoc 内容类检查（`JavadocMethod` / `MissingJavadocType` 等）被 `suppressions.xml` 整体豁免。 + +**实际落地与 §5.2 的两处偏差**： +- `Connector` 上 11 个空安全读取口没有逐个加「不得覆写」注释（11 行近乎相同的注释是噪音），改为在**类文档里写一次**、覆盖全部 `supportsXxx` / `requiresXxx` / `supportedWriteOperations`，并说明反面（返回 `null` 的取得器才是声明点）。 +- `ConnectorStatisticsOps` / `ConnectorMetadata` 的改动只加生命周期与线程段落，未碰 08 号负责的文案，按 §七 的约定执行。 diff --git

+**（1）`ConnectorTableOps.listPartitionValues`**（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorTableOps.java:493-498`，签名紧随其后的 `:499-501`）文档写「Used by the `partition_values()` TVF and by column-distinct-value optimizations」。实测 `fe-core/src/main` 下这个方法名零命中；`partition_values()` 表函数的真实路径是 `MetadataGenerator.java:2035` → `PluginDrivenExternalTable.getNameToPartitionValues`（`:882`）→ `metadata.listPartitions`（`:899`）。 + +**（2）`ConnectorScanRangeType`**（`.../api/scan/ConnectorScanRangeType.java:20-33`）文档写「Each type maps to a specific Thrift scan range variant」，`ConnectorScanRange.java:33-35` 与 `ConnectorScanPlanProvider.java:44-51` 也重复了同样的话。实测 `fe-core/src/main` 从不调 `getRangeType()` 或 `getScanRangeType()`；分片一律被包成 `PluginDrivenSplit extends FileSplit`（`PluginDrivenSplit.java:35-47`），真正区分格式的是 `ConnectorScanRange.populateRangeParams`（`ConnectorScanRange.java:182`）的多态覆写。 + +**（3）`ConnectorEventSource.getCurrentEventId`**（`.../api/event/ConnectorEventSource.java:44-49`）文档写「Used by the master to cheaply decide whether there is anything new to pull before calling `pollOnce`」。实测唯一命中是 hms 的实现（`HmsEventSource.java:58`）；引擎侧的元存储事件驱动只调 `pollOnce`（`MetastoreEventSyncDriver.java:164`）。 + +**（4）`ConnectorContractValidator`**（`.../api/ConnectorContractValidator.java:29-34`）文档写这些不变量「are enforced by the per-connector contract tests (which build each connector and call validate)」。实测只有四个连接器的测试在调：iceberg（`IcebergConnectorTest.java:368`）、es（`EsScanPlanProviderTest.java:332`）、maxcompute（`MaxComputeConnectorContractTest.java:66`）、jdbc（`JdbcDorisConnectorTest.java:187`）。而 `:57-62` 与 `:65-69` 那两条关于「按分区哈希写」的不变量，唯一声明该能力的连接器是 hive（`HiveWritePlanProvider.java:139`），hive 的测试里没有任何 `validate` 调用——真实连接器上没有正样本，只有 `fe-core` 里用假连接器构造的 `ConnectorContractValidatorTest` 覆盖。另外该类校验的是连接器级取得器（`connector.requiresPartitionHashWrite()`），而引擎写路径读的是按表重载（`Connector.java:167-171`，经 `PluginDrivenExternalTable.requirePartitionHashOnWrite`，`:378-390`）。 + +**（5）`ConnectorProcedureOps.getSupportedProcedures`**（`.../api/procedure/ConnectorProcedureOps.java:48-52`）文档写「used by the engine for routing, validation, and SHOW-style discovery」。实测：路由按表类型（`ExecuteActionFactory.java:57-59`）加执行模式（`ConnectorExecuteAction.java:142` 的 `getExecutionMode`）；未知过程名由连接器在 `execute` 内部拒绝，引擎侧的 `isSupported` 恒返回 true 并在注释里写明了这一点（`ConnectorExecuteAction.java:227-231`）；唯一读取点 `ExecuteActionFactory.getSupportedActions`（`:78-89`）自身零生产调用方，注释自陈是「no live caller today」的预留。 + +**（6）`ConnectorPartitionInfo.orderedPartitionValues`**（`.../api/ConnectorPartitionInfo.java:52-61`）文档写「Empty means "not supplied": fe-core then falls back to parsing partitionName itself (unchanged behavior)」。实测 `fe-core` 侧的名字解析兜底已经删除，`PluginDrivenMvccExternalTable.java:328-332` 写着「There is no name-parsing fallback anymore」，并用 `Preconditions.checkState(partitionValues.size() == types.size(), ...)` 做元数硬校验；这个抛出被调用方的 try/catch 接住（`:271-302`），后果是该分区被跳过、整表退化成「无分区」。 + +**（7）`ConnectorMvccSnapshot`**（`.../api/mvcc/ConnectorMvccSnapshot.java:25-32` 与 `:77`）类文档写「serialized into BE scan ranges so the read path sees a consistent version」，`getProperties()` 文档写「Connector-specific metadata propagated to BE」。实测这个类连 `Serializable` 都没实现（`:34`）；引擎不把它放进任何分片，`properties` 的唯一消费者是连接器自己的 `applySnapshot`（paimon `PaimonConnectorMetadata.java:757-769`、iceberg `:2092`、hudi `:594/:645`），这条契约写在 `ConnectorMetadata.java:151-160`。 + +**（8）`ConnectorMetadata.getSyntheticScanPredicates`**（`.../api/ConnectorMetadata.java:169-185`）文档写「the engine NEVER discriminates by connector here; it applies whatever the connector returns」。前半句是真的，后半句不成立：反向转换器 `ConnectorExpressionToNereidsConverter` 只接受 `ConnectorAnd`、五种比较（EQ/LT/LE/GT/GE，`:100-114`）、能按名绑定到扫描输出列的列引用（`:124-135`）和 STRING 字面量（`:144-155`），其余一律抛 `AnalysisException`（类注释 `:53-59` 明确说这是有意的 fail loud）。 + +**（9）`ConnectorPushdownOps.supportsCastPredicatePushdown`**（`.../api/ConnectorPushdownOps.java:60-74`）文档写「When this returns false, the engine will strip any conjuncts containing CAST expressions from the filter before passing it to the connector」。实测这个剥离只发生在残余谓词那条路上（`PluginDrivenScanNode.buildRemainingFilter`，`:2053-2079`）；`applyFilter` 那条路上引擎直接把全部 conjuncts 转换后交给连接器（`convertPredicate`，`:874-878` 调 `buildFilterConstraint`），不查这个能力位。而正向转换器遇到 CAST 是**直接把外壳拆掉、只推里面的子表达式**（`ExprToConnectorExpressionConverter.java:108-109`：`return convert(expr.getChild(0));`），连接器看到的是一个「看起来没有类型转换」的谓词，没有任何标记可供自查。今天覆写这个方法的是 paimon（恒 false）、maxcompute（恒 false）、jdbc（按会话开关）；实现了 `applyFilter` 的三个连接器 hive、hudi、trino 全部继承默认值 `true`。 + +**（10）内部代号**：`Connector.java:217` 写着「Design S8: storage-property derivation is owned by the connector」；`handle/ConnectorTransaction.java:79` 与 `pushdown/ConnectorPredicate.java:24` 各写着一个「(O5-2)」。另有六处裸工单号 `#65329`（`ConnectorColumn.java:61/147/217/222`、`ConnectorType.java:81`、`ConnectorTableOps.java:326`）。 + +## 三、为什么这是个问题 + +公共接口的 javadoc 是新连接器作者唯一的行为契约来源——他不会去读 `fe-core`，读不了也不该读（连接器是独立打包、独立类加载器的插件）。文档说错引擎行为，代价有三种，且都已经在这九条里出现： + +1. **照文档写就是写错。** 第 6 条最典型：文档承诺「不填分区值，fe-core 会自己解析分区名」，照此实现的新连接器会得到「所有分区被跳过 → 表被当成无分区表 → 分区裁剪全丢、`EXPLAIN` 显示 `partition=0/0`」。这是用户能观察到的性能塌陷，而且不报错、不告警，只在日志里留一条 warn。 +2. **排查成本白烧。** 第 2、3、5 条都是「文档说引擎会读，引擎不读」。作者按文档设置了值、发现不生效，就会去翻引擎，翻不到东西，最后只能靠读全仓才敢下结论。 +3. **文档把一个真实隐患描述成了已经解决的问题。** 第 9 条最危险：文档让人相信「返回 false 就安全了」，而实际 `applyFilter` 路径完全不看这个位。hive 的 `applyFilter` 会用等值谓词直接裁掉元存储分区（`HiveConnectorMetadata.java:1085-1116`），拿到的又是被拆掉类型转换外壳的谓词——一旦源侧的比较语义与 Doris 的强转语义不一致，就是**多裁分区、少返回行，而且 BE 复算补不回来**（分区已经不在扫描范围里）。这一条的行为后果是代码路径推断，未跑端到端验证，但机制是确证的。 + +内部代号那几处是另一类问题：这些文件最终会随 PR 进上游社区，`Design S8` / `O5-2` 对仓库外的读者是纯噪音，而且它替换掉了本该写在那里的技术理由。 + +## 四、用一个最小例子说明 + +拿第 9 条（隐式类型转换那条）举例。假设一张 hive 分区表，分区列 `dt` 是 `STRING` 类型： + +```sql +CREATE TABLE hive_catalog.db.t (id INT, v STRING) PARTITIONED BY (dt STRING); +SELECT * FROM hive_catalog.db.t WHERE dt = 20240101; -- 注意右边是数字，不是字符串 +``` + +| 环节 | 文档让人以为会发生 | 实际发生 | 应该被文档写成 | +|---|---|---|---| +| Doris 分析谓词 | —— | 变成 `CAST(dt AS INT) = 20240101` | 同 | +| 引擎要不要剥掉这个含转换的谓词 | 「hive 没声明支持转换下推 → 引擎会剥」 | hive 继承了默认值 `true`（没声明过），而且 `applyFilter` 这条路根本不查这个位 | 只有残余谓词那条路才会剥；`applyFilter` 从不剥 | +| 连接器收到什么 | 收不到这个谓词 | 收到 `dt = 20240101`（转换外壳被正向转换器拆掉了） | 连接器收到的比较可能已被拆壳，且无从自查 | +| 后果 | 无 | hive 用它去裁元存储分区；若源侧的字符串/数字比较语义与 Doris 不同，就少扫分区、少返回行 | 明确写出这个风险由连接器承担 | + +「新人照文档写」的另一面，用第 6 条一句话说明：新连接器实现 `listPartitions` 时，按文档「值可以不填，fe-core 会解析名字」只填 `partitionName` —— 今天的真实结果是这张表所有分区都被静默跳过，表变成「无分区」。 + +## 五、解决方案 + +### 5.1 目标状态 + +除下面这一条待拍板项外，**全部是 javadoc 文字改动，零签名改动、零行为改动**。 + +待拍板项：`ConnectorPushdownOps.supportsCastPredicatePushdown` 的默认值。 + +```java +// 现状（ConnectorPushdownOps.java:72-74） +default boolean supportsCastPredicatePushdown(ConnectorSession session) { + return true; +} + +// 选项 A（调研报告的建议，安全侧）：默认 false，能正确处理拆壳后比较语义的连接器显式声明 true +default boolean supportsCastPredicatePushdown(ConnectorSession session) { + return false; +} +``` + +三个选项，请你选一个： + +- **选项 A：默认翻成 false。** 与本仓库既有纪律（能力用 `supportsXxx()` 默认 false 的 opt-in 声明）一致。**新发现的代价**：今天 iceberg、hive、hudi、es、trino 五个连接器全都继承 `true`（hive 网关下挂的 iceberg-on-HMS 等异构表同样受影响），翻转会让它们在残余谓词那条路上失去含类型转换谓词的下推（正确性上更安全，但可能变慢）；要恢复就得逐个连接器判断「拆壳后的比较语义与远端是否一致」，而连接器目前无从自查，这个判断没有客观依据。所以选 A 意味着一次跨五个连接器的行为改动，不适合和文档批一起走。 +- **选项 B（推荐）：本批只改文档，默认值不动。** 把两条路径的差异、正向转换器拆壳的事实、以及「风险由连接器承担」写进 javadoc，保持这个批次零行为改动；默认值翻转与逐连接器判断另开一项，配端到端回归。 +- **选项 C：彻底修。** 引擎在拆壳处给该比较打标记，连接器能自查后再决定默认值。这需要在公共接口上加表达能力，超出本任务范围，只作为远期方向记录。 + +### 5.2 改动清单 + +| 文件（均在

`getOrCreateClient()`（`HiveConnector.java:256-258`），如果在无元存储的单测环境里构造不出来，**不要硬凑**——改为在 `ConnectorContractValidator` 的 javadoc 里如实记下这个缺口即可。 + +### 5.3 明确不要顺手做的事 + +- **不要顺手删接口。** 这九条里有三条的符号是另一个任务的删除对象；本任务不承担删除，也不承担「先标过时」。 +- **不要顺手改 `supportsCastPredicatePushdown` 的默认值**，除非你拿到的答复是选项 A；即使是 A，也要作为独立提交、配逐连接器判断与回归，不要混进文档批。 +- **不要顺手修 `ConnectorPartitionInfo` 里那条 NULL 标记的文档**（`:41-49`）——它与 `PluginDrivenMvccExternalTable.java:334-336` 的校验一致，是对的。 +- **不要顺手改 `ConnectorMetadata.getSyntheticScanPredicates` 的引擎侧行为**去支持更多表达式节点。反向转换器有意 fail loud，扩语法是另一件事。 +- **不要为「文档与实现是否一致」写 shell 或正则门禁。** 本仓库已有结论：这类门禁只适合存在性与前缀类不变量，理解语言语义的活轮不到它，误报比漏报更毒。文档一致性靠评审。 +- **不要在 `fe-core` 里补代码去迎合旧文档**（例如把删掉的分区名解析兜底加回来）。当前阶段 `fe-core` 只出不进，正确做法是改文档、让连接器提供数据。 +- **不要顺手统一异常分层、命名或重载堆叠**，那些是调研报告里另外的条目。 + +## 六、怎么验证 + +1. **编译门禁（最强单一信号）**：全反应堆含测试源编译，禁用跳过测试编译的参数。 + `mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile`（不要加 `-Dmaven.test.skip=true`）。纯 javadoc 改动本身不会破坏编译，这一步的作用是抓「顺手改了签名却没改调用方」以及 `{@link}` 指向不存在符号导致的 javadoc/checkstyle 失败。 +2. **代码风格**：javadoc 行长受 checkstyle 限制，改完跑 FE 的 checkstyle（`fe-code-style` 那套），确认零新增告警。 +3. **`{@link}` 有效性自查**：本次新增的交叉引用（`ConnectorMetadata.applySnapshot`、`Connector.requiresPartitionHashWrite(ConnectorTableHandle)`、反向转换器类名）逐个 grep 确认符号存在且可见性允许被链接（`ConnectorExpressionToNereidsConverter` 在 `fe-core` 里，连接器模块看不到它，**只能以文字提及，不能写成 `{@link}`**）。 +4. **单元测试**：选项 B（只改文档）时无需新增测试，也不需要变异验证——没有可变异的行为。若采纳选项 A，则至少要改 `JdbcConnectorMetadataTest.testDefaultPushdownOps_alwaysTrue`（`:211-216` 现在断言默认为 `true`），并为 hive / hudi / trino 各补一条「显式声明」的断言；跑测试必须禁用 maven build cache，否则 surefire 会被静默跳过而 `BUILD SUCCESS` 是空的。 +5. **端到端回归**：选项 B 不需要。选项 A 需要，且必须覆盖 hive 分区表上含隐式类型转换的等值谓词（分区裁剪结果与行数）。 +6. **代号清理的收尾检查**：在两个公共模块的 `src/main` 下重跑一次代号 grep，确认零命中： + `grep -rnE "Design [A-Z][0-9]+|\([A-Z][0-9]+-[0-9]+\)" fe/fe-connector/fe-connector-api/src/main fe/fe-connector/fe-connector-spi/src/main` + +## 七、风险与回退 + +- 文档改动的风险只有一种：**把新的错话写进去**。对策是这份文档里每条断言都带了实测位置，动手时逐条重新 grep 一遍（以符号名为准，不要相信行号），改完请一个没参与的人对着代码复核一遍文字。 +- 与删除任务的重叠已在 5.2 隔离。若删除任务先落地，本任务对应三行自然作废；若本任务先落地又不小心改了那三处，删除任务会把它们连注释一起删掉，不产生冲突，只是白做。 +- 回退成本为零：全部是注释，`git revert` 即可，无持久化格式、无有线格式、无类型标签涉及。 +- 唯一的真实风险来自选项 A（翻默认值）：它会让五个连接器在残余谓词路径上少推谓词，属于「更安全但可能更慢」，且一旦为了恢复性能给某个连接器显式声明 `true`，就等于把一个无从自查的正确性风险重新打开。因此建议单独走，不与本批混提。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` 第 11.2 节：本任务的对照表来源（九行「文档说的 vs 实际」）。 +- 同一报告第十一节开头四条「有用户可见后果的缺陷」：其中隐式类型转换那条与本任务的待拍板项同源，但归责在连接器侧，另开修复。 +- 同一报告主题四（「没有调用方或没有实现方的接口面」）的 7.2、7.3 两张删除表：`listPartitionValues`、`ConnectorScanRangeType` 一族、`getCurrentEventId` 都在其中，对应本文 5.2 的重叠三行。 +- 同一报告第十节（「接口契约写得不完整」）：`listFileSizes`、`resolveTimeTravel` 两条是「实现对、文档错」，处置方式与本任务同类，但属于异常契约那一批，不在本任务范围。 +- 同一报告第十四节（「被推翻或收窄的说法」）：动手前值得看一眼，避免把有理由的设计当成缺陷改坏。 +- 本任务应与「把公共接口的书写规则写下来」那个任务同批提交：那份规则里应当包含「javadoc 描述引擎行为时必须给出可核实的引擎侧位置」这一条，本任务是它的第一次应用。 + +--- + +## 九、施工后订正与落地口径（2026-07-25） + +**拍板结果：选项 B**——本批只改文档，`supportsCastPredicatePushdown` 的默认值不动；翻转另开一项，需配逐连接器判断与端到端回归。 + +复核发现的订正（**以本节为准**）： + +1. **第（2）条要收窄：`getRangeType()` 不是死的。** fe-core 确实从不读它，但 `fe-connector-api` 自己的 `ConnectorScanRange.populateRangeParams` **默认实现**读它，并把 `connector_scan_range_type=` 写进 `TTableFormatFileDesc` 的 jdbc 参数——这是 BE 可见的字符串，而 jdbc 是唯一不覆写 `populateRangeParams` 的连接器，所以这条默认路径是活的。**「引擎从不读」这句话必须限定为「fe-core 从不读」，并且删除分片类型枚举族的那个任务要按「会改变 jdbc 发给 BE 的内容」处理**（已在那份任务文档里加了警示）。本批未改这三处文档（按原约定留给删除批次）。 +2. **第（9）条的风险面比文档写的宽**：不只 hive，hudi 也用同样的方式从等值/`IN` 谓词裁分区（trino 则把约束转交给 trino 自己的元数据），所以「拆壳后比较语义不一致 → 少扫分区」的风险对这三个连接器都成立。已按此写进 javadoc。同时 hive 的裁剪不只吃等值，还吃未取反的 `IN` 列表。 +3. **第（7）条的读取方多一处**：`properties` 除了三个连接器的 `applySnapshot`，还有 hudi 的 `getSyntheticScanPredicates` 会读；fe-core 全程不读。已按此写。 +4. **第（10）条的代号清理已做完**：`Design S8` 1 处、`(O5-2)` 2 处、裸工单号 6 处，全部改成行为描述；两个公共模块 `src/main` 的代号正则复扫为零命中。 +5. **可选的 hive 契约测试正样本没做**：按 §5.2 末尾的处置，未硬凑；`ConnectorContractValidator` 的类文档已如实记下这个缺口（两条按分区哈希写的不变量在真实连接器上无正样本）。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/09-complete-pushdown-expression-contract.md

+ +## 二、背景：现在的代码是怎么写的 + +**这个包提供什么。** `fe-connector-api` 的 `pushdown` 包有 18 个类，构成一棵中立表达式树：根接口 `ConnectorExpression` 与谓词标记 `ConnectorPredicate`，节点 `ConnectorAnd` / `ConnectorOr` / `ConnectorNot` / `ConnectorComparison` / `ConnectorIn` / `ConnectorIsNull` / `ConnectorBetween` / `ConnectorLike` / `ConnectorFunctionCall` / `ConnectorColumnRef` / `ConnectorLiteral`，入参载体 `ConnectorFilterConstraint` 与 `ConnectorColumnAssignment`，加上三个"应答"载体 `FilterApplicationResult` / `ProjectionApplicationResult` / `LimitApplicationResult`。 + +**契约总量。** 每个节点类只有一句话的 javadoc。两个最关键的： + +- `ConnectorComparison.java:24-28`： + `Binary comparison: left op right.` ＋ `Supported operators: EQ, NE, LT, LE, GT, GE, EQ_FOR_NULL.` + 枚举本体（`:34-52`）只给了七个符号串（`EQ("=")` … `EQ_FOR_NULL("<=>")`）。没有一处说明右操作数可能是空值字面量、`EQ_FOR_NULL` 在字面量非空与为空两种情形下分别是什么意思。 +- `ConnectorLike.java:24-26`： + `A LIKE/REGEXP predicate: {@code value LIKE pattern}.` + 没有转义符、没有 `%` 与 `_` 的方言说明、没有说 `REGEXP` 是部分匹配还是整串锚定、没有说大小写敏感性。 + +**表达式是谁生产的，两条到达路径不一样。** 生产者只有 fe-core 的 `ExprToConnectorExpressionConverter`（另外两个入口 `NereidsToConnectorExpressionConverter:232-234` 与 `UnboundExpressionToConnectorPredicateConverter` 都转手复用它，所以字面量编码全仓一致）。它到达连接器有两条路，**只有第二条会剥掉带 CAST 的谓词**： + +| 路径 | 引擎侧构造点 | 是否按 `supportsCastPredicatePushdown` 剥 CAST | +|---|---|---| +| `ConnectorPushdownOps.applyFilter`（`:38-44`）收到的 `ConnectorFilterConstraint` | `PluginDrivenScanNode.java:2043-2046` `buildFilterConstraint` | **不剥**，原样给 | +| `planScan` / `getScanNodePropertiesResult` 收到的 `Optional filter` | `PluginDrivenScanNode.java:2053-2079` `buildRemainingFilter` | 剥（`supportsCastPredicatePushdown` 为 false 时） | + +且 `convertConjuncts`（`ExprToConnectorExpressionConverter.java:135-147`）在只有一个 conjunct 时**直接返回那一个节点，不包 `ConnectorAnd`**；无 conjunct 时返回布尔真字面量。 + +**字面量里实际会装什么。** `ConnectorLiteral.java:29-32` 的 javadoc 声称是 `(null, Boolean, Integer, Long, Double, String, BigDecimal, LocalDate, LocalDateTime)`。对照真实生产代码 `ExprToConnectorExpressionConverter.java:288-322`：`IntLiteral.getValue()` 返回 `long`，`FloatLiteral.getValue()` 返回 `double`，`LargeIntLiteral` 三个分支都不匹配、落到兜底 `literal.getStringValue()`。所以引擎实际产出的集合是：`null` / `Boolean` / `Long` / `Double` / `BigDecimal` / `String` / `LocalDate` / `LocalDateTime`——**`Integer` 永远不会出现**（`ConnectorLiteral.ofInt` 只被测试用到），而 `LARGEINT` 字面量会以 `String` 到达。 + +**两套"连接器吃掉了哪些谓词"的协议，只有一套真的生效。** + +| 协议 | 连接器怎么表达 | 引擎实际怎么处理 | +|---|---|---| +| `FilterApplicationResult.getRemainingFilter()`（`:45-47`） | 返回剩余表达式，或 `null` 表示全吃掉 | `PluginDrivenScanNode.java:883-892`：`null` → `conjuncts.clear()`；**非 `null` → 一个 conjunct 都不摘**（注释写明细粒度反查 deferred to a future enhancement） | +| `ScanNodePropertiesResult` 的 `notPushedConjunctIndices`（`:52-65`） | 报出**没被**吃掉的下标 | `PluginDrivenScanNode.java:1847-1892`：按下标反查并真的摘除；`hasConjunctTracking()` 为 false 时不摘 | + +现实是：全仓三个 `applyFilter` 实现（`HiveConnectorMetadata.java:1115-1116`、`HudiConnectorMetadata.java:312`、`TrinoConnectorDorisMetadata.java:292-296`）都把原表达式原样当残差返回，没人返回 `null`；而下标协议全仓只有一个实现方（`EsScanPlanProvider.java:165,220`）。也就是说今天所有连接器的谓词都会在 BE 侧被复算一遍。 + +**顺带一个文档 bug**：`ConnectorScanPlanProvider.java:446-447` 说默认实现"wraps getScanNodeProperties with an empty not-pushed set, meaning all conjuncts are assumed to have been pushed"。但 `:459-461` 走的是单参构造器 → `hasConjunctTracking = false` → 引擎**一个也不摘**。文档说的语义和真实语义正好相反。 + +## 三、为什么这是个问题 + +**第一，它是三条已知丢行缺陷的同一个根因。** 五个连接器各自实现了同一段翻译，四家蒙对一家蒙错： + +| 连接器 | `EQ_FOR_NULL` 怎么处理 | 结果 | +|---|---|---| +| iceberg（`IcebergPredicateConverter.java:245-251`） | 字面量为空 → `isNull`；非空 → `equal` | 对 | +| trino（`TrinoPredicateConverter.java:132-140`） | 同上，显式判 `isNull()` | 对 | +| maxcompute（`MaxComputePredicateConverter.java:168-174`） | 远端没有对应算子 → 落到 default → 放弃下推 | 对（且注释写明了理由） | +| es | 有专门测试覆盖 | 对 | +| paimon（`PaimonPredicateConverter.java:144-176`） | `:157-159` 先把空字面量挡掉 → `:173-174` 无条件 `builder.isNull(idx)` | **错**：`WHERE c <=> 5` 变成 `c IS NULL` | + +`ConnectorLike` 那侧同理：paimon 只要模式"不以 `%` 开头且以 `%` 结尾"就转成前缀匹配（`PaimonPredicateConverter.java:234-237`），对 `_` 和被转义的 `%` 毫无守卫；es 是唯一实现了转义处理的（`EsQueryDslBuilder.java:547-567`）；jdbc 把模式原样拼进远端 SQL（`JdbcQueryBuilder.java:424-432`）；`REGEXP` 在 es 直接交给 ES 的 `regexp` 查询（`:661-666`，Lucene 语义是整串锚定），在 jdbc 交给远端数据库的 `REGEXP`（多数是部分匹配）——同一棵表达式树，两种锚定语义，接口没说哪种是对的。 + +**第二，"过宽安全、过窄致命"这条最重要的规则从来没写下来，而且它有前提条件。** 用户观察到的后果是：查询不报错，只是少了行；`EXPLAIN` 看不出异常；BE 也补不回来——因为连接器已经在文件/分区级别把数据跳过了，根本没送到 BE。反过来"过宽"之所以安全，恰恰是因为引擎保留了 conjuncts 让 BE 复算（见上一节的两套协议）；一旦连接器通过残差协议声明"这些谓词我全吃了"，过宽就会**多返回行**。这两件事必须写在同一处，否则连接器作者只会读到半句话。 + +**第三，接口把"安全方向"当成了普适的，但它按用途反转。** 同一棵表达式树有三个用途，三种正确做法： + +| 用途 | 丢一个 conjunct 意味着 | 正确做法 | +|---|---|---| +| 扫描下推（`applyFilter` / `planScan`） | 过滤变宽 → BE 复算兜住 | 允许放弃，禁止收窄 | +| 写时冲突检测（`ConnectorTransaction.applyWriteConstraint`） | 冲突检测范围变宽 → 更保守 | 允许放弃 | +| `ALTER TABLE … EXECUTE … WHERE` 的重写范围 | 重写更多文件，极端情况整表重写 | **必须报错**，不许放弃（`UnboundExpressionToConnectorPredicateConverter.java:71-79` 已这样实现并写了注释） | + +这条只在一个 fe-core 内部类的注释里，公共模块里读不到。 + +## 四、用一个最小例子说明 + +一张 paimon 表，`c` 列有两行：`c = 5` 和 `c = NULL`。 + +| 用户写的 SQL | 今天实际发生什么 | 应该发生什么 | +|---|---|---| +| `SELECT * FROM t WHERE c <=> 5` | 连接器把它翻成 `c IS NULL`，paimon 按此裁掉含 `c=5` 的数据文件 → **返回 0 行** | 返回 1 行（`c=5`）。翻不出来就整条别下推，让 BE 自己过滤 | +| `SELECT * FROM t WHERE s LIKE 'a_c%'` | 翻成 `startsWith("a_c")` → `'abc'` 这行被数据源跳过 → **少行** | `'abc'` 应当命中。模式里有 `_` 就不能当前缀用 | + +两条的共同点：**连接器写出了一个比用户谓词更窄的过滤条件**，而更窄的下推条件在架构上是不可恢复的。契约要写的就是这一句： + +```text +翻译规则（连接器实现方必读）： + 能精确表达 → 下推 + 不能精确表达 → 整条放弃（返回 null / 不吃这个 conjunct），交给 BE + 不允许 → 下推一个"差不多"的、范围更小的近似 +并且：只有在你没有通过残差协议声明"已全部吃掉"时，过宽才是安全的。 +``` + +## 五、解决方案 + +### 5.1 目标状态 + +**（1）包级说明。** 新增 `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/pushdown/package-info.java`，把下面六件事一次写清（英文 javadoc，与仓库其余注释一致）： + +1. 这棵树是谁生产的、两条到达路径的差别（`applyFilter` 拿到的表达式**未剥** CAST；`planScan` / `getScanNodePropertiesResult` 拿到的已按 `supportsCastPredicatePushdown` 剥过）；单 conjunct 时根节点不是 `ConnectorAnd`；空 conjunct 时是布尔真字面量。 +2. **总则**：不能精确表达就整条放弃，禁止返回更窄的近似；并说明"过宽为何安全"的前提是引擎仍保留 conjuncts。 +3. 安全方向按用途反转的三行表（扫描 / 写冲突 / EXECUTE 重写），指向 `applyWriteConstraint` 与 `UnboundExpressionToConnectorPredicateConverter` 的既有注释。 +4. 字面量取值域：引擎实际产出的 8 种 Java 类型，逐 Doris 类型对照（含 `TINYINT`/`SMALLINT`/`INT`/`BIGINT` 一律 `Long`、`FLOAT`/`DOUBLE` 一律 `Double`、`LARGEINT` 是 `String`、`DATE` 是 `LocalDate`、`DATETIME` 是 `LocalDateTime`、其余类型兜底为 `Expr.getStringValue()` 的 `String`），并写明 `Integer` 不会出现。 +5. 两套残差协议的**实际效力**（照抄第二节那张表的结论），明确"返回 remainingFilter 不等于引擎会替你摘 conjunct"。 +6. 零参数 `ConnectorFunctionCall` 的陷阱：`ExprToConnectorExpressionConverter.java:342-354` 对无法识别的表达式会构造一个**函数名是原始 Doris SQL 文本、参数列表为空**的 `ConnectorFunctionCall`。它不是函数调用，连接器不得按函数名匹配语义（jdbc 在 `JdbcQueryBuilder.java:492-495` 刻意把它当预渲染 SQL 片段处理）。 + +**（2）逐算子语义写到类上。** `ConnectorComparison` 的 javadoc 补出七个算子的语义，其中 `EQ_FOR_NULL` 必须写成两种情形： + +```java +/** + * ... + *

    EQ_FOR_NULL ({@code <=>}) is Doris' null-safe equality and has TWO cases that MUST be + * distinguished; collapsing them loses rows:

    + *
      + *
    • right operand is a NULL literal ({@code ConnectorLiteral#isNull()}): + * equivalent to {@code IS NULL}.
      • + *
    • right operand is a NON-NULL literal: equivalent to plain {@code EQ} — + * it is NOT {@code IS NULL}. Translating {@code c <=> 5} to {@code c IS NULL} + * silently drops every matching row.
      • + *
    + *

    A connector whose dialect has no null-safe form must drop the whole conjunct + * (see the package javadoc); it must never substitute a narrower predicate.

    + */ +``` + +**（3）`ConnectorLike` 的方言写清**：`%` 匹配任意长度、`_` 匹配单字符、转义符是反斜杠（因此模式里 `\%` `\_` 是字面量）、`REGEXP` 是**部分匹配**（Doris 语义，未锚定）、大小写敏感性随列的排序规则、以及一条已核实的表示能力边界——Doris 的 `LIKE … ESCAPE ` 三参形态（`nereids/trees/expressions/Like.java:46,106-116`）**无法**用 `ConnectorLike` 表示（它只有 value/pattern 两个孩子，且 `ExprToConnectorExpressionConverter.java:117-122` 只在 `size() == 2` 时才构造它），因此连接器只需按固定的反斜杠转义符处理。 + +**（4）修正三处与实现矛盾的文档**（都在下推与扫描应答面上，见 5.3 的分工约定）：`ConnectorLiteral` 的 Java 类型清单、`FilterApplicationResult.getRemainingFilter` 的实际效力、`ConnectorScanPlanProvider.java:446-447` 那句说反了的默认语义。 + +**（5）可选的中立工具方法（一个类、一个方法）。** 只做真正能消灭一类缺陷的那一个： + +```java +public final class ConnectorLikePatterns { + private ConnectorLikePatterns() {} + + /** + * Returns the literal prefix iff {@code pattern} is exactly "literal text + one trailing %" + * (no other %, no _, no backslash escape). Empty otherwise — the caller must then NOT + * narrow the predicate to a prefix match. + */ + public static Optional exactPrefix(String pattern); +} +``` + +`EQ_FOR_NULL` 那侧**不加**工具方法：判断本身只有一行（算子 ＋ `isNull()`），而 iceberg / trino 已各自写对，为了复用去改它们等于给零收益的改动加上非零风险。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +| `fe-connector-api/…/api/pushdown/package-info.java`（新增） | 写入 5.1(1) 的六节包级契约 | +|

`ConnectorScanPlanProvider` / `ScanNodePropertiesResult` 上与残差协议相关的那几行归本任务，其余归任务 08。动手前请先看任务 08 的清单是否已包含这几处并划掉。 + +## 六、怎么验证 + +**编译门禁（最强的单一信号）。** 全反应堆含测试源编译： + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T 1C test-compile +``` + +不得使用任何跳过测试编译的参数。javadoc 改动会被 checkstyle 扫到（本仓库 checkstyle 也扫测试源），因此这一步同时验证注释格式合法。 + +**单元测试（仅当采纳可选工具方法时）。** 新增 `ConnectorLikePatternsTest`，断言必须编码"为什么"而不只是"是什么"——每个用例的名字直接说明它防的是哪种丢行： + +| 模式 | 期望 | 这条测试在防什么 | +|---|---|---| +| `abc%` | `Optional.of("abc")` | 正常前缀仍然可以下推，不能因为守卫过严丢掉优化 | +| `a_c%` | `Optional.empty()` | `_` 被当字面量 → 前缀匹配会漏掉 `abc` | +| `a\%c%` | `Optional.empty()` | 被转义的 `%` 是字面百分号 | +| `%abc%` | `Optional.empty()` | 前置 `%` 不是前缀匹配 | +| `a%b%` | `Optional.empty()` | 中间还有通配符 | +| `abc`（无 `%`） | `Optional.empty()` | 这是等值而非前缀，交给调用方按等值处理 | + +**变异验证。** 把 `exactPrefix` 的守卫逐条删掉（先删 `_` 检查，再删转义检查），确认对应用例各自失败。若删掉某个守卫后测试仍全绿，说明该用例没有真的覆盖它。 + +**端到端回归：本任务不需要。** 改的是注释与一个纯函数，运行时行为不变。真正需要端到端回归的是任务 01 / 02 / 03 的连接器修复（`WHERE c <=> 5` 与 `LIKE 'a_c%'` 在 paimon 表上的行数断言），本任务不要替它们跑。 + +**验收口径。** ① 上面的 `test-compile` 为 `BUILD SUCCESS`；② 5.2 表格逐行完成；③ 一个没读过这段代码的人只读 `package-info.java`，能独立回答三个问题：`c <=> 5` 该翻成什么、`LIKE 'a_c%'` 能不能翻成前缀匹配、返回 `remainingFilter` 之后引擎会不会替我摘 conjunct。 + +## 七、风险与回退 + +风险来自两处，都可控： + +- **写错契约比不写更糟。** 契约一旦写下就会被后来的连接器当权威照做。因此本文所有事实性陈述都必须在动手时复核一遍（尤其"引擎实际产出哪些 Java 类型"和"两套残差协议的实际效力"这两段）；凡是没能在代码里坐实的推断，宁可写成"目前由各连接器自行决定"，不要写成规则。 +- **可选工具方法有溢出风险。** 它落在公共模块，一旦有连接器调用就成了公共 API。控制手段：只提供一个方法、语义收紧到"要么给出确定的前缀、要么明确说不行"，且不强制任何连接器改用它。 + +回退：注释改动 `git revert` 即可，无数据、无持久化、无有线格式影响。可选工具类若被判定不需要，单独摘掉它与它的测试即可，其余文档改动不受影响。 + +## 八、相关背景 + +- `audit-report.md`「11.1 四个有实际用户可见后果的缺陷」—— 四条会被用户看到的丢行/丢名缺陷：第（3）（4）条是本任务的直接依据，并写明这两个 paimon 缺陷与上游既有实现相同、不是本次迁移引入的回退；第（4）条的行为后果是代码路径推断，未跑端到端验证。 +- `audit-report.md` 附录 A.4 第 84 条 —— 两套残差协议只有一套生效：完整证据链。 +- `audit-report.md` 第十六节「明确不建议动的部分」第 9 项 —— 两套残差协议不合并、只补文档：这条决定就是本任务的定位。 +- 同目录任务 07（写下两个公共模块的设计规则）：本任务是它在 `pushdown` 这一包上的细化；如果 07 先落地，本任务的包级说明应该引用它而不是重述。 +- 同目录任务 08（修正陈旧接口文档）：文档改动的分工见 5.3 最后一条。 +- 同目录任务 01 / 02 / 03：本任务是这三条的共同根因，它们是本任务契约的第一批"使用者"。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/10-split-table-ops-by-domain.md

`extends` 列表，`ConnectorTableOps` 在第 46 行）。 + +**本任务成立的关键事实（已在 `HEAD` 上重新核实）**：全仓库没有任何一处把 `ConnectorTableOps` 当成静态类型使用——没有变量、参数、返回值、字段、泛型实参用它。全部命中只有三类： + +- `ConnectorMetadata.java:46` 的 `extends` 一行； +- javadoc 与注释里的引用：`fe-core` 侧 8 处（`PluginDrivenExternalCatalog.java:393/572/651/692/797/903/1003/1084`，全是 `{@code}` 文本）、`fe-connector-api` 侧 11 处非声明引用； +- 各连接器里的分节注释（如 `HiveConnectorMetadata.java:386` 的 `// ========== ConnectorTableOps ==========`），以及 `fe-core` 测试里的一处分节注释（`FakeConnectorPluginTest.java:114`）。 + +其中真正需要在本任务里动的是 7 处 **成员级** javadoc 链接：`ConnectorCapability.java:36`（指向 `getColumnsFromQuery`）、`:42`（`listPartitions`）、`:89`（`viewExists`）、`:90`（`listViewNames`），以及 `ConnectorColumnPosition.java:24-25`（`addColumn` / `modifyColumn`）、`ConnectorMvccPartitionView.java:29`（`listPartitions`），另有两处成员级的 `{@code}` 文本引用同样会因拆分变成陈旧描述，要一并改准：`ConnectorViewDefinition.java:27`（`ConnectorTableOps.getViewDefinition`）与 `ConnectorCreateTableRequest.java:30`（`ConnectorTableOps.createTable(session, request)`）。指向类型本身的链接（`ConnectorCapability.java:175`、`ConnectorColumnPath.java:28`）不用动，因为聚合接口名保留。 + +## 三、为什么这是个问题 + +**第一，「新连接器该覆写什么」这个信息今天在代码里根本不存在。** `ConnectorMetadata` 加它继承的 6 个 `Ops` 子接口一共 81 个方法，`default` 计数分别是：`ConnectorMetadata` 自身 11、`ConnectorSchemaOps` 7、`ConnectorTableOps` 46、`ConnectorPushdownOps` 4、`ConnectorStatisticsOps` 5、`ConnectorWriteOps` 5、`ConnectorIdentifierOps` 3——**抽象方法 0 个**。也就是说 `class XConnectorMetadata implements ConnectorMetadata { }` 是一个合法的、能编译过的空实现。 + +**第二，「必须实现」的方法里有一半的默认值是静默的空值，不是报错。** 这才是「编译能过但一行不工作」的具体机制：`getTableHandle` 默认返回 `Optional.empty()`（46 行）、`listTableNames` 默认返回空列表（179 行），都不报错；只有 `getTableSchema`(97) 与 `getColumnHandles`(136) 是 fail-loud 的。所以一个漏实现的连接器不会在启动时炸，而是在用户面前表现成「目录是空的」。 + +**第三，连维护者自己都记不清有没有强制方法。** `fe/fe-connector/fe-connector-api/src/test/java/org/apache/doris/connector/api/ConnectorSchemaOpsDefaultsTest.java:38` 的注释写的是「A bare metadata implementing only the one abstract SPI method」——这句话在 `HEAD` 上已经是错的（没有抽象方法了）。文档与代码脱节到这个程度，说明「靠口头传承最少实现集」不可行。 + +**第四，四组只有一个数据源用得上的方法对其余连接器是纯噪音**：分支与标签（4 个）、分区规格演进（3 个）、执行裸 SQL、透传查询取列。一个只读连接器的作者要在 46 个方法里逐个判断「这个跟我有关吗」。 + +需要说明的是：**目标不是把接口拆到多小**。Trino 的 `ConnectorMetadata` 是上百个全默认方法的巨接口，同样靠文档告诉实现者最少实现集——所以 46 个全默认方法本身不异常。真问题是**没有分域、也没有写最少实现集**。 + +调研实测的覆写分布可以直接当作最少实现集的证据（统计口径：各连接器元数据实现类里 `@Override` 且方法名属于 `ConnectorTableOps`）： + +| 连接器 | 覆写的 `ConnectorTableOps` 方法名个数 | +|---|---| +| iceberg | 35 | +| hive | 31 | +| paimon | 13 | +| maxcompute | 10 | +| jdbc | 9 | +| hudi | 8 | +| es | 5 | +| trino | 4 | + +8 个连接器**无一例外**都覆写的是 4 个：`getTableHandle`、`listTableNames`、`getTableSchema`、`getColumnHandles`。再加上 8 个里有 7 个覆写的 `buildTableDescriptor`（唯一的例外是 trino，它吃引擎的通用兜底描述符），构成「表基础」域的无条件最少实现集，不是拍脑袋定的。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 X。我写下这一个类，它能编译过： + +```java +public class XConnectorMetadata implements ConnectorMetadata { +} +``` + +然后用户在 `x` 目录上做这几件事： + +| 用户写了什么 | 今天实际发生什么 | 应该发生什么 | +|---|---|---| +| `SHOW TABLES FROM x.db` | 返回**空列表**，不报错（`listTableNames` 默认返回空列表） | 作者一开始就知道 `listTableNames` 属于「表基础」域的无条件最少实现集 | +| `SELECT * FROM x.db.t` | 报「表不存在」（`getTableHandle` 默认返回 `Optional.empty()`），像是用户打错了表名 | 同上，`getTableHandle` 在最少实现集里 | +| `DESC x.db.t` | 抛 `getTableSchema not implemented` | 唯一一条今天就能告诉作者「你漏了」的路径 | +| `ALTER TABLE x.db.t ADD BRANCH b1` | 抛「CREATE/REPLACE BRANCH not supported」 | 这一族本就与 X 无关；拆分后它在独立的「快照引用」域里，作者一眼就知道整域可以不看 | + +第一行的「返回空列表不报错」有测试固化：`fe/fe-core/src/test/java/org/apache/doris/connector/fake/FakeConnectorPluginTest.java:117-118`（`// SHOW TABLES against an unimplemented connector returns empty rather than throwing.`）。这是有意的设计，不是缺陷——但正因为默认值是静默的，「哪些必须实现」就必须写在文档里，否则无处可寻。 + +## 五、解决方案 + +### 5.1 目标状态 + +`ConnectorTableOps` 变成一个不声明任何方法的聚合接口（外加两个暂未归域的残留方法），46 个方法按域分到 6 个新接口。**签名一个字都不改，包名不变（都在 `org.apache.doris.connector.api`）。** + +```java +public interface ConnectorTableOps extends + ConnectorTableMetadataOps, // 表基础：14 + ConnectorViewOps, // 视图：4 + ConnectorTableDdlOps, // 表级 DDL：5 + ConnectorColumnEvolutionOps, // 列演进：11 + ConnectorSnapshotRefOps, // 快照引用与分区规格演进：7 + ConnectorPartitionListingOps { // 分区列举：3 + + // 暂未归域（2 个）：jdbc 直通。等「把 jdbc 直通摘成可选接口」那一批处理， + // 现在放在聚合上而不是硬塞进某个域，避免给它们一个错误的归属。 + default void executeStmt(ConnectorSession session, String stmt) { ... } + default ConnectorTableSchema getColumnsFromQuery(ConnectorSession session, String query) { ... } +} +``` + +6 个域接口与各自的最少实现集（这一节的内容就是要写进各接口类文档的正文）： + +**1. `ConnectorTableMetadataOps`（14 个）**：`getTableHandle`、`listTableNames`、`getTableSchema`×2、`getColumnHandles`×2、`supportsColumnHandleSnapshotPin`、`getTableComment`、`getPrimaryKeys`、`renderShowCreateTableDdl`、`listSupportedSysTables`、`getSysTableHandle`、`isPartitionValuesSysTable`、`buildTableDescriptor`。 +- 无条件必须：`getTableHandle`、`listTableNames`、`getTableSchema(session, handle)`、`getColumnHandles(session, handle)`（8/8 连接器全覆写）、`buildTableDescriptor`（8 个里 7 个覆写，只有 trino 未实现；它的唯一消费方是 `PluginDrivenExternalTable.java:1343`，返回 `null` 会退到引擎的通用兜底描述符，这也是 trino 今天能不实现的原因）。 +- 支持时间旅行或模式演进才必须：`getTableSchema(..., snapshot)`、`getColumnHandles(..., snapshot)`、`supportsColumnHandleSnapshotPin`（三者要么全实现要么全不实现；只实现前两个而不声明第三个，会让引擎跳过「绑定列必须有句柄」的 fail-loud 检查）。 +- 暴露系统表才必须：`listSupportedSysTables` + `getSysTableHandle`；`isPartitionValuesSysTable` 只在该系统表走通用分区值表函数时覆写。 +- 其余按需：`getTableComment`、`getPrimaryKeys`、`renderShowCreateTableDdl`。 + +**2. `ConnectorViewOps`（4 个）**：`viewExists`、`listViewNames`、`getViewDefinition`、`dropView`。 +- 最少实现集：整域可空。声明 `ConnectorCapability.SUPPORTS_VIEW` 后，`viewExists` + `getViewDefinition` 必须（否则 `getViewDefinition` 的默认会抛）；`listViewNames` 只在 `listTableNames` **不**含视图时必须（iceberg 属于这种）；`dropView` 只在支持 `DROP VIEW` 时。 + +**3. `ConnectorTableDdlOps`（5 个）**：`createTable`×2、`dropTable`、`renameTable`、`truncateTable`。 +- 最少实现集：支持建表就必须实现 `createTable(session, request)` 这个**全量**重载，**不要**只实现旧的窄重载——全量重载的默认实现（241-249 行）会把 `PARTITION BY` / 分桶 / `EXTERNAL` / `IF NOT EXISTS` 静默丢掉，只实现窄签名的后果是「建表成功但分区丢了」。这一条必须在类文档里写成警告。 +- 其余按需：`dropTable`、`renameTable`、`truncateTable`。 + +**4. `ConnectorColumnEvolutionOps`（11 个）**：顶层 6 个 + 嵌套 4 个 + `modifyColumnComment`。 +- 最少实现集：整域可空。支持列变更时顶层 6 个（`addColumn`、`addColumns`、`dropColumn`、`renameColumn`、`modifyColumn`、`reorderColumns`）成组实现（hive 与 iceberg 都是这 6 个全覆写）；嵌套 4 个 + `modifyColumnComment` 只在支持嵌套列演进时（目前只有 iceberg）。原文件 325-333 行那段说明嵌套路径约定的注释要整段搬到这个接口的类文档里。 + +**5. `ConnectorSnapshotRefOps`（7 个）**：分支标签 4 个 + 分区规格演进 3 个。 +- 最少实现集：整域可空，这是给「有快照引用概念」的数据源的。要点：分支/标签 4 个方法要么全实现要么全不实现——只实现一半会让 `CREATE BRANCH` 成功而 `DROP BRANCH` 报「不支持」。 + +**6. `ConnectorPartitionListingOps`（3 个）**：`listPartitionNames`、`listPartitions`、`listPartitionValues`。 +- 最少实现集：分区表连接器必须 `listPartitionNames` + `listPartitions`。`listPartitionValues` **不要**实现：它零生产调用方（详见任务清单里删死接口那一批），文档必须点明，否则新作者会照着现有的三个实现继续抄。 + +**机器可读的标记**：在 `fe-connector-api` 新增一个纯文档用途的注解，作为最少实现集的**唯一真源**（类文档负责解释「为什么」，注解负责「是哪些」）： + +```java +@Documented +@Retention(RetentionPolicy.RUNTIME) +@Target(ElementType.METHOD) +public @interface ConnectorMustImplement { + /** 空串 = 无条件必须；否则写触发前提（能力名或一句话条件）。 */ + String when() default ""; +} +``` + +`RUNTIME` 保留期只为让单元测试能反射读到它。**生产代码不读它，不做任何运行时校验，也不加 shell/正则门禁**——本仓库已有结论：那类门禁只适合存在性与前缀类不变量，要理解语言语义就会误报，而误报比漏报更毒。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +| `.../connector/api/ConnectorTableMetadataOps.java`

**默认实现体里的方法调用不跨域**，已逐条核实：`getTableSchema(..., snapshot)` 调 `getTableSchema(...)`（同域）、`getColumnHandles(..., snapshot)` 调 `getColumnHandles(...)`（同域）、`createTable(request)` 调 `createTable(schema, props)`（同域）。所以 6 个域接口**互不继承**，也不会出现同一方法在两个域里声明的钻石问题。 +2. `import` 要按域重新分配，`UnusedImports` 与 `CustomImportOrder`（`fe/check/checkstyle/checkstyle.xml:160-167`）会卡住遗漏。 +3. 域接口内的 `{@link #xxx}` 若目标方法落在别的域里，要改成 `{@link ConnectorXxxOps#xxx}`。已知一处：`listViewNames` 的文档引用了 `listTableNames`。 + +### 5.3 明确不要顺手做的事 + +- **不要改任何方法签名，不要合并重载，不要删任何方法。** 删 `listPartitionValues`、收 `createTable` 旧窄重载、删 `getPrimaryKeys`，都在「删死接口」那两批里，各自有独立的连带改动（要动连接器与单测）。本任务混进去就不再是零破坏，也会让第六节那条「方法集合完全一致」的断言失效。 +- **不要动连接器**，包括那些 `// ========== ConnectorTableOps ==========` 分节注释：聚合接口名保留，注释仍然准确；改它会把一个纯公共模块的改动扩散成 8 个模块。 +- **不要把 `buildTableDescriptor` 的 7 个散列标量参数改成传句柄。** 那是 thrift 边界那一批的事，本任务只给它安个域。 +- **不要给注解加运行时校验**，也不要在 `Connector` 注册路径上做任何检查——那会把每个连接器的元数据对象构造提前，本仓库已有先例说明代价（见 `ConnectorContractValidator` 类文档解释为什么校验放在契约测试而不是注册路径）。 +- **不要顺手把另外 5 个 `Ops` 子接口也拆了。** 它们分别只有 3～7 个方法，不构成可发现性问题；本任务只需要在各自类文档里补最少实现集就够，但那属于「文档据实」那一批。 +- **不要写 shell 门禁**去校验「新连接器是否实现了标记方法」。 + +## 六、怎么验证 + +**第一，全反应堆含测试源编译（最强的单一符号级信号）**： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile -Dmaven.build.cache.enabled=false +``` + +必须 `BUILD SUCCESS`，且**禁用**任何跳过测试编译的参数。这一条通过就直接证明了零破坏：8 个连接器与 `fe-core` 的全部 `@Override` 仍然绑得上。（注意 `fe/.mvn/maven.config` 已带 `-Dmaven.build.cache.cacheCompile=false`，但跑测试时仍要显式关掉整个构建缓存，否则 surefire 会被静默跳过而 `BUILD SUCCESS` 是空的。） + +**第二，方法集合冻结测试**（新建 `ConnectorMetadataSurfaceTest`，junit5，与 `fe-connector-api` 现有测试同风格）： + +1. **拆分前**在 `HEAD` 上生成基线：反射 `ConnectorMetadata.class.getMethods()`，过滤掉 `isSynthetic()`，把「方法名 + 参数类型全限定名列表」渲染成每行一条、排序后写入 `src/test/resources/connector-metadata-methods.txt`。按上面的计数，基线应为 **81 条**（11+7+46+4+5+5+3；`close()` 已被 `ConnectorMetadata.java:232` 的默认实现覆盖，计在 11 里）——但要**机械生成**，不要照抄这个数字。 +2. 测试断言：运行时算出的集合与基线文件**完全相等**（不只是数量相等；不相等时把差集打印出来，方便判断是漏搬还是签名手误）。 + - 这条能失败的场景：搬移时手抖改了参数类型、漏搬一个方法、把某个重载写成了同一签名。 + - 这条测试在后续「删死接口」批次里会红——那是**故意的**，基线文件必须跟着那一批一起有意识地更新，这正是给公共接口加的减速带。类文档要写明这一点。 +3. 断言每个 `@ConnectorMustImplement` 标记都落在 6 个域接口之一**自己声明**的方法上（用 `getDeclaredMethods()` 判定），且 6 个域接口各至少有一个标记或在类文档里显式说明「整域可空」——防止标记随手打在聚合接口上，让「域 → 最少实现集」这个映射保持成立。 +4. 断言无条件标记（`when()` 为空串）的方法集合恰好是那 5 个（`getTableHandle`、`listTableNames`、`getTableSchema(session, handle)`、`getColumnHandles(session, handle)`、`buildTableDescriptor`）。这条把「前 4 个 8/8 连接器实测都覆写、`buildTableDescriptor` 8 个里 7 个覆写」这个证据钉在测试里；将来要把第 6 个方法升为无条件必须，必须先改这条断言，从而被迫说明理由。 + +**变异验证**：第 2 条断言的变异是「从任一域接口里删掉一个方法」→ 必须红；第 4 条的变异是「把 `renderShowCreateTableDdl` 也标成无条件必须」→ 必须红（它只有 hive 一个实现）。两个变异都要实际跑一遍确认会红，而不是只在脑子里推。 + +**端到端回归**：不需要。本任务不改任何签名、不改任何默认实现体、不改任何连接器，运行时字节行为逐条不变。全反应堆含测试源编译 + `fe-connector-api` 与 `fe-core` 的既有单测（尤其 `FakeConnectorPluginTest`、`ConnectorSchemaOpsDefaultsTest`）通过即可。 + +## 七、风险与回退 + +风险低，来源只有两个，都是机械性的： + +- **搬移时漏搬或改错签名。** 由第六节第 2 条断言 + 全反应堆含测试源编译双重兜底。任一环节红就是漏搬。 +- **javadoc 链接指向搬走的方法。** 影响仅限文档渲染，不影响编译。`{@link ConnectorTableOps#addColumn}` 这种写法在方法搬到父接口后仍能解析（javadoc 会查继承来的成员），所以即使漏改也不会断链；但 5.2 列的那 9 处仍应改准，避免读者被指到聚合接口上找不到方法体。 + +回退成本近似于零：改动集中在一个模块的公共接口文件，`git revert` 单个提交即可，不涉及任何持久化格式、thrift 有线格式或连接器插件包。也**不涉及** Gson 持久化的类型标签——本任务不新增也不删除任何被持久化的类型。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md`： + - **第六节「主题三：大接口把互不相干的职责捆在一起」**（6.1 现状规模的接口尺寸表、6.2 哪些不是问题、6.3 建议的形状与「无一处当静态类型用」这条有利事实）； + - **附录结论 113**（`ConnectorTableOps` 把 8 类职责与两种寻址风格捆在一个 46 方法接口里，判定「部分成立」，收窄理由值得一读）； + - **第十五节「建议的整治路线」第 3 批**（本任务在整套路线里的位置：仅公共模块、无风险、为后续每一批划定域边界）； + - **第七节 7.2 / 7.3**（后续要删的死接口面，含 `listPartitionValues`、`getPrimaryKeys`、`createTable` 旧窄重载——本任务只给它们安域、不动它们）。 +- 与本任务紧邻的两个后续任务：把 jdbc 直通（`executeStmt` / `getColumnsFromQuery`）摘成可选接口；thrift 边界整治（`buildTableDescriptor` 的参数形状）。本任务刻意为这两个留了钩子（前者放在聚合上不归域，后者归入表基础但只安域不改形状）。 + +--- + +## 九、施工后订正（2026-07-25 落地） + +**已完成。** 6 个域接口 + 1 个注解 + 冻结测试 + 基线资源，`ConnectorTableOps` 从 504 行缩到 69 行的聚合；连接器与 fe-core 零改动。 + +复核订正（**§三、§5.1 里下列说法以本节为准**）： + +1. **§114 的「带快照的三个方法要么全实现要么全不实现」被推翻。** 实测只有 paimon 3/3；hive、hudi、iceberg 各只实现 `getTableSchema(..., snapshot)`，而且 `supportsColumnHandleSnapshotPin` 的注释里明确祝福了 iceberg 走 false 那条路。类文档因此写成：只实现 schema 那个是常态，列句柄的快照重载是**更强的**一步，只有当句柄按钉住的名字建键时才实现，并同时声明 pin。 +2. **§5.1-5 的「分支/标签实现一半」在今天是假想风险**（iceberg 与 hive 都 4/4，分区规格演进也都 3/3）。但**同一失效模式在列演进域是真的**：网关委派了 6 个顶层列操作、漏了 5 个路径列操作。已作为独立缺陷修复（见 README「调研期发现、已修复的真实缺口」）。类文档按「假想风险 + 真实前例」写。 +3. **`listViewNames` 的必要条件要写准**：只有当连接器的 `listTableNames` **减掉**视图时才必须实现——今天只有 iceberg，且只在启用视图目录时才减；非视图目录的 iceberg 目录 `listTableNames` 仍含视图。 +4. **窄重载 `createTable(session, schema, properties)` 今天零实现**（4 个支持建表的连接器全部实现 request 重载），这条比文档原来的说法更有力，已写进类文档。 +5. **`ConnectorTableOps` 原有 15 个 import（不是 16）**；拆完后聚合接口零 import。 +6. **需要改的成员级引用是 9 处**，另有 2 处（iceberg 连接器里提到 `ConnectorTableOps.getTableComment` 的注释）只提聚合接口名、无需改动。跨域的 `{@link}` 只有一处（`listViewNames` → `listTableNames`），已改成指向新接口。 +7. **`@ConnectorMustImplement` 的无条件集合**最终是 5 个：取表句柄、列表名、取 schema、取列句柄、构造表描述符。冻结测试第 4 条断言把它钉住。 +8. **验证口径修正**：全反应堆 `test-compile` 必须**排除两个 shade 模块**（`fe-connector-hms-hive-shade`、`fe-connector-paimon-hive-shade`），否则 hive 相关模块必然报 `package org.apache.hadoop.hive.conf does not exist`——那是反应堆用未 shade 的 `target/classes` 解析依赖导致的，与改动无关。§六 的命令要按这个改。 +9. **两个变异都实际跑过并确认变红**：删掉某个域接口里的一个方法 → 方法集合断言红；把 `renderShowCreateTableDdl` 标成无条件必须 → 无条件集合断言红。 diff --git

为准，核对时以符号名为准，不要以行号为准。 + +## 一、一句话说明这个任务要解决什么 + +连接器公共接口上有一批方法、字段和整个类，既没有任何连接器实现，也没有任何引擎代码消费；这一批当中有 10 项可以在**完全不碰连接器生产代码**的前提下删掉，本任务把它们删干净，让公共接口第一次真正变小而不是变大。 + +## 二、背景：现在的代码是怎么写的 + +调研报告列了约 20 项「可以直接删」的死面。逐条在 `7ff51a106f0` 上重扫之后，**这 20 项里只有 10 项真的不碰连接器生产代码**，另外 8 项各有 1 到 8 个连接器在实现或构造它们（详见 5.3）。本任务只做前 10 项。下面把这 10 项的现状讲清楚。 + +**1）连接器属性描述符机制（`ConnectorPropertyMetadata`）** +`fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorPropertyMetadata.java` 是一个 120 行的泛型类，提供 `stringProperty` / `intProperty` / `booleanProperty` 等工厂，用来描述「连接器暴露哪些配置项」。`Connector.java:234-242` 上挂着两个默认方法把它返回出来： + +```java + /** Returns the table-level property descriptors. */ + default List> getTableProperties() { ... } + /** Returns the session-level property descriptors. */ + default List> getSessionProperties() { ... } +``` + +全仓库对 `ConnectorPropertyMetadata` 只有 15 处命中，全部在这个类自身和上面两个默认方法里。八个连接器一个都没有覆写这两个方法。 +**特别注意同名不同义**：真正给 `SHOW CREATE TABLE` 渲染 `PROPERTIES (...)` 的是 `fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenExternalTable.java:768` 的 `getTableProperties()`，它返回 `Map`，由 `Env.java:4881` 消费，**是活的，不许动**。同样，`ConnectorSession.java:89` 的 `getSessionProperties()` 返回 `Map`，被 hive / iceberg / paimon / jdbc / hudi / es / maxcompute 大量读取，也**是活的，不许动**。要删的只是 `Connector` 这个接口上返回描述符列表的两个方法。 + +**2）两个空句柄接口** +`handle/ConnectorPartitionHandle.java:25` 是一个 `extends Serializable` 的空接口，全仓库只有它自己这一处命中。 +`handle/ConnectorTransactionHandle.java:23` 也是空接口，唯一引用来自同目录的 `ConnectorTransaction.java:35`（`extends ConnectorTransactionHandle`），而它的存在理由写在 `ConnectorTransaction.java:32` 的注释里：「Extends the marker ConnectorTransactionHandle so that existing APIs that traffic in opaque handles continue to work without change」。核实结果：全仓库没有任何方法以 `ConnectorTransactionHandle` 作参数或返回值，这句注释在代码里为假。 + +**3）`applyLimit` 与 `LimitApplicationResult`** +`ConnectorPushdownOps.java:53-59` 声明了默认返回 `Optional.empty()` 的 `applyLimit`，八个连接器零覆写。`pushdown/LimitApplicationResult.java` 是配套的 70 行结果类，零构造点。 +但它不是「零调用」——引擎真的在调：`fe-core/src/main/java/org/apache/doris/datasource/scan/PluginDrivenScanNode.java:911-921` 的 `tryPushDownLimit()` 调用 `metadata.applyLimit(...)`，并在 `getSplits()` 里的 `1261` 行执行。这一点很关键，见第三节。 + +**4）`ConnectorMvccSnapshot` 的描述与时间戳字段** +`mvcc/ConnectorMvccSnapshot.java:37-38` 有 `timestampMillis` 与 `description` 两个字段，配 builder setter（`151-162`）、getter（`59-66`）以及 `equals`/`hashCode`/`toString` 中的项。全仓库对这两个 setter/getter 的调用只出现在公共模块自带的 `ConnectorMvccSnapshotTest.java`。生产侧的 `ConnectorMvccSnapshot.builder()` 调用点有 20 多个（hive、iceberg、paimon、hudi 和 fe-core），全部只用 `snapshotId` / `schemaId` / `lastModifiedFreshness` / `properties`，没有一处调 `.description(...)` 或 `.timestampMillis(...)`。这个类没有 Gson 注解，也不过 thrift。 + +**5）两个统计类的 `UNKNOWN` 常量** +`ConnectorTableStatistics.java:29` 与 `ConnectorColumnStatistics.java:36` 各有一个 `public static final ... UNKNOWN` 哨兵（分别是 `(-1, -1)` 和 `(-1, -1, -1, -1)`），类文档写着「statistics 不可用时用 UNKNOWN」。全仓库对这两个常量零引用。而 `ConnectorStatisticsOps.java:33/52/67` 的真实签名是 `Optional` / `Optional`——「不可用」的约定其实是 `Optional.empty()`。 + +**6）`ConnectorPartitionValueDef` 与 `ConnectorPartitionSpec.getInitialValues`** +`ddl/ConnectorPartitionValueDef.java` 是 77 行的分区值定义类，唯一引用者是 `ddl/ConnectorPartitionSpec.java`（字段 `:48`、两个构造参数 `:52`/`:59`、getter `:79`）。而 `ConnectorPartitionSpec.java:86-88` 自己的注释就写明了它恒为空： + +> The neutral converter does not lower those value expressions into `getInitialValues()` (it stays empty), so this flag preserves the information a connector needs to reject them + +真正被消费的是布尔位 `hasExplicitPartitionValues()`（hive 用它拒绝显式分区值）。唯一生产构造点 `fe-core/src/main/java/org/apache/doris/connector/ddl/CreateTableInfoToConnectorRequestConverter.java:149` 传的就是 `Collections.emptyList()`。 + +**7）`ConnectorCreateTableRequest.isExternal`** +`ddl/ConnectorCreateTableRequest.java:115-117` 的 `isExternal()`，由 `CreateTableInfoToConnectorRequestConverter.java:75` 的 `.external(info.isExternal())` 填入。核实结果：有生产者，零消费者——八个连接器没有一个读过它，类文档也没说清「external」在连接器语境下意味着什么。（调研报告写的「零消费者、零文档」需要修正为「有生产者、零消费者、零语义文档」。） + +**8）`ConnectorTestResult` 的子组件机制** +`ConnectorTestResult.java:36`（`componentResults` 字段）、`:62-70`（`withComponents` 工厂）、`:80-83`（`getComponentResults`）以及 `:89-96`（`toString` 里的拼接）。全仓库零调用。另外 `:100-110` 的 `equals` 只比 `success` 与 `message`，**故意或无意地忽略了 `componentResults`**——留着它就是留一个「两个不等的对象相等」的坑。引擎侧只消费 `isSuccess()` 与 `getMessage()`。 + +**9）`ConnectorType` 的四个整表子列表取得器** +`ConnectorType.java:249-268` 的 `getChildrenNullable` / `getChildrenComments` / `getChildrenFieldIds` / `getChildrenCommentSpecified`，全仓库（含全部测试）零调用；实际使用的都是同类里的按索引访问器。 + +## 三、为什么这是个问题 + +三条真实伤害，逐条对应上面的现状： + +1. **公共接口在向每个新连接器收税，而收来的东西没人用。** 一个新连接器作者读 `Connector` 接口会看到两个属性描述符方法、读 `ConnectorPartitionSpec` 会看到一个分区值列表、读 `ConnectorCreateTableRequest` 会看到 `isExternal()`——他要么白花时间实现，要么白花时间确认「不实现行不行」。这批面越留越长，每一次「新增连接器要读多少接口」的评估都被它抬高。 + +2. **文档说的和代码做的不一致，会制造排查浪费。** `ConnectorTransaction` 说自己是为了兼容「以不透明句柄传递事务的既有接口」，但那种接口不存在；两个统计类说「不可用时用 `UNKNOWN`」，但签名要求的是 `Optional.empty()`——照文档写的连接器会返回 `Optional.of(UNKNOWN)`，让「没有统计」变成「行数 -1」，引擎侧对 -1 的处理和对 `empty` 的处理不是一回事。这类文档不是无害的装饰，它会把人引到错的实现上。 + +3. **`applyLimit` 留着比删掉危险，这是本批唯一有正确性含义的一项。** 引擎在 `PluginDrivenScanNode.getSplits()` 里的调用顺序是： + - `1261`：`tryPushDownLimit()` → 调 `metadata.applyLimit(...)`； + - `1318`：`buildRemainingFilter()` → 若连接器不支持带隐式类型转换的谓词下推，这里会把含类型转换的谓词**剥掉**，并把 `filteredToOriginalIndex` 置为非 null； + - `1341`：`long sourceLimit = effectiveSourceLimit(limit, filteredToOriginalIndex != null);` → 一旦剥过谓词，就把传给 `planScan` 的 LIMIT 抑制掉。第 `1326-1333` 行的注释把理由写得很清楚：连接器看到的过滤条件已经不反映被剥掉的谓词，此时若在数据源侧应用 LIMIT，取回的行会被后续在 BE 上重新求值的谓词再砍一刀，**结果少返回行**。 + + 问题在于这条安全抑制只作用于 `sourceLimit`，而 `applyLimit` 在它之前 80 行就已经调过了。也就是说：今天没人实现 `applyLimit`，所以没事；哪天有连接器实现了它（接口摆在那儿、名字又直白，这是完全可能的），它就会在「谓词已被剥掉」的情况下拿到完整 LIMIT 并把它下推下去，用户看到的是**查询少返回行**，且只在带隐式类型转换的谓词 + LIMIT 的组合下出现——极难定位。删掉这个方法与它的结果类，等于把这个陷阱拆掉；真要做 LIMIT 下推，也应该在正确的位置（谓词剥离之后）重新设计入口。 + +**不建议「先加过时标注、下个版本再删」。** 这些都是内部接口，仓库外没有实现者；打上过时标注只会让公共接口再长一岁而不缩小。分批删 + 每批全反应堆含测试源编译，已经足够安全。 + +## 四、用一个最小例子说明 + +用 `applyLimit` 这一项举例，因为它是本批唯一「留着有正确性风险」的。假设 hive 表 `t` 有 100 万行，`a` 是字符串列，用户写： + +```sql +SELECT * FROM hive_catalog.db.t WHERE a = 1 LIMIT 10; +``` + +`a = 1` 会被分析成「把字符串列隐式转成数字再比较」，也就是含隐式类型转换的谓词。 + +| 用户写了什么 | 今天实际发生什么 | 如果哪天有人实现了 `applyLimit` | +|---|---|---| +| `WHERE a = 1 LIMIT 10` | 引擎发现 hive 不支持带类型转换的谓词下推，把这个谓词剥掉；因为剥过，`sourceLimit` 被抑制成「不下推 LIMIT」；数据源扫全表，BE 端重新算 `a = 1` 并取前 10 行 → **结果正确** | `applyLimit` 在谓词剥离之前就被调用，把 `LIMIT 10` 交给了数据源；数据源在没有 `a = 1` 的情况下取 10 行还给 BE；BE 再用 `a = 1` 过滤这 10 行 → **可能只返回 1 行甚至 0 行，用户看到结果少了** | + +同一段 SQL，接口面留着与删掉的区别不在性能而在正确性。删掉之后，任何人想做 LIMIT 下推都必须重新加入口，而那时他会看到 `effectiveSourceLimit` 这条抑制并绕不过去。 + +## 五、解决方案 + +### 5.1 目标状态 + +改完之后： + +- `fe-connector-api` 少掉 5 个类文件：`ConnectorPropertyMetadata`、`handle/ConnectorPartitionHandle`、`handle/ConnectorTransactionHandle`、`pushdown/LimitApplicationResult`、`ddl/ConnectorPartitionValueDef`（其中 `ConnectorPartitionValueDef` 与 `LimitApplicationResult` 是配套删）。 +- `Connector` 接口不再有属性描述符方法；`ConnectorPushdownOps` 只剩 `applyFilter` / `applyProjection` / `supportsCastPredicatePushdown`。 +- `ConnectorTransaction` 的声明变成： + +```java +public interface ConnectorTransaction extends Closeable { +``` + +（连带删掉 `ConnectorTransaction.java:32-33` 那段说明「为兼容不透明句柄接口」的注释。） + +- `ConnectorPartitionSpec` 的两个构造收成一个，签名草案： + +```java +public ConnectorPartitionSpec(Style style, List fields); +public ConnectorPartitionSpec(Style style, List fields, + boolean hasExplicitPartitionValues); +``` + +- `ConnectorTestResult` 只剩 `success()` / `success(String)` / `failure(String)` / `isSuccess()` / `getMessage()`，`equals` 与实际字段重新一致。 +- `ConnectorMvccSnapshot` 只剩 `snapshotId` / `schemaId` / `lastModifiedFreshness` / `properties`。 +- 两个统计类不再有 `UNKNOWN`，类文档改成指向 `Optional.empty()` 这一个约定。 +- `fe-core` 的 `PluginDrivenScanNode` 不再有 `tryPushDownLimit()`；`getSplits()` 里 `1261` 那行连同上面「Attempt limit and projection pushdown via SPI protocol」的注释一起去掉（投影下推的调用在别处，不受影响）。 + +### 5.2 改动清单 + +`api` 指 `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/`。 + +| 序号 | 文件 | 做什么

A（建议）**：按上表删掉。理由是「一个零消费者、零语义说明的布尔位挂在公共建表请求上」本身就在误导——连接器作者会以为自己该读它，读了又不知道该怎么用。真需要时按当时的语义重新加，成本只有几行。 +- **选项 B**：保留，但**必须同时**补两件事：一是在类文档里写明「external 在连接器语境下的确切含义」（是 `CREATE EXTERNAL TABLE` 语法位，还是元存储的表类型？），二是让至少一个连接器真正读它并据此改变行为（例如 hive 建表时决定写 `EXTERNAL_TABLE` 还是 `MANAGED_TABLE`）。 +- **选项 C（不允许）**：维持现状——零消费 + 零文档地留着。 + +调研报告里还有一项同性质的判断题（`ConnectorTableOps.getPrimaryKeys` 与

为什么不在本批 | +|---|---| +| `ConnectorEventSource.getCurrentEventId` | `fe-connector-hms` 的 `HmsEventSource.java:58` 有真实实现（且 `pollForMaster` 内部又自己读了一次同样的 id）；删接口方法必须同时删这个覆写 | +| `ConnectorScanPlanProvider.estimateScanRangeCount` | `fe-connector-jdbc` 的 `JdbcScanPlanProvider.java:152` 有一个恒返回 1 的实现 | +| 两个 `ApplicationResult` 上的 `precalculateStatistics` | `LimitApplicationResult` 随本批整类删除，但 `FilterApplicationResult` 的这个必填参数有三个生产构造点：hive `HiveConnectorMetadata.java:1115`、hudi `HudiConnectorMetadata.java:312`、trino

+**第二类：名字撞车、绝对不能顺手删的活代码。** + +- `ConnectorScanRange.getTableFormatType()`（`api/scan/ConnectorScanRange.java:121`）与 `ConnectorTableSchema.getTableFormatType()`（`ConnectorTableSchema.java:150`）**同名不同义**。前者是活的有线协议字段，被 `PluginDrivenScanNode.java:1793` 写进 thrift 的 `tableFormatFileDesc`。本批不碰 `tableFormatType`，但仍在这里点名，以防后续批次误删。 +- `PluginDrivenExternalTable.getTableProperties()`（返回 `Map`）与 `ConnectorSession.getSessionProperties()`（返回 `Map`）都是活的，与本批要删的 `Connector` 上两个同名方法毫无关系。 +- `fe-connector-trino` 与 `be-java-extensions/trino-connector-scanner` 里出现的 `ConnectorTransactionHandle` / `LimitApplicationResult` / `ProjectionApplicationResult` 都是 `io.trino.spi.connector.*`，是 Trino 自己 SPI 的同名类，一行都不许动。 + +**第三类：范围纪律。** +- 不要顺手把 `ConnectorTestResult` 的 `equals` 忽略字段这类问题「顺便修好」再保留字段——本批的处置就是删字段，删完 `equals` 自然一致。 +- 不要为「让删除后能编译」往 `fe-core` 新增任何数据源相关代码；本批只删不加。 +- 不要写 shell 或正则的构建门禁去防止这些符号复活。它们已经不存在了，编译就是最强的约束；这类门禁只适合存在性与前缀类不变量。 + +## 六、怎么验证 + +**1）编译（最强的单一信号）。** 全反应堆、**含测试源**： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T 1C test-compile +``` + +禁止任何跳过测试编译的参数。本批的核心风险就是「某处还引用着已删符号」，而这条命令覆盖 `fe-core`、`fe-connector-api` 和八个连接器的主源与测试源，是唯一能一次证明「引用全清」的动作。`BUILD SUCCESS` 之外任何 symbol not found 都必须当场处理，不许注释掉测试绕过。 + +**2）单元测试（必须关掉构建缓存，否则测试会被静默跳过而仍报 BUILD SUCCESS）。** 至少跑这四组： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -Dmaven.build.cache.enabled=false \ + -pl fe-connector/fe-connector-api,fe-core test \ + -Dtest=ConnectorMvccSnapshotTest,FakeConnectorPluginTest,CreateTableInfoToConnectorRequestConverterTest +``` + +外加三个连接器的分区相关测试（改过测试源实参的那些）：`HiveConnectorMetadataDdlTest`、`IcebergSchemaBuilderTest`、`PaimonSchemaBuilderTest`、`PaimonConnectorMetadataDdlTest`、`IcebergConnectorMetadataDdlTest`。 + +**3）测试要断言的是什么（不是「还能跑」）。** +- `ConnectorMvccSnapshotTest` 删掉描述与时间戳的断言后，**必须仍然覆盖** `equals`/`hashCode` 对 `snapshotId`、`schemaId`、`lastModifiedFreshness`、`properties` 的敏感性——这四个是活的，快照身份靠它们区分。如果删完之后这个测试只剩「构造不抛异常」，那就是把测试的意图删掉了，要补回差异断言。 +- `CreateTableInfoToConnectorRequestConverterTest` 删掉 `getInitialValues()` 断言后，**必须仍然断言 `hasExplicitPartitionValues()`**。做一次变异验证：手工把 `CreateTableInfoToConnectorRequestConverter` 里传给 `ConnectorPartitionSpec` 的这个布尔位改成恒 `false`，`HiveConnectorMetadataDdlTest` 里「hive 拒绝显式分区值」那条用例必须变红。变红说明我们删掉的是死的那半（值列表），保住的是活的那半（布尔位）；不变红说明保护不足，要补断言。 + +**4）删除彻底性自查（人工一次，不做成门禁）。** 对下列符号在全仓库 grep，期望零命中（`io.trino.spi.connector.*` 的同名类除外）：`ConnectorPropertyMetadata`、`ConnectorPartitionHandle`、`ConnectorPartitionValueDef`、`getInitialValues`、`applyLimit(`（`ShowCommand.applyLimit` 是完全无关的同名方法，需排除）、`withComponents`、`getComponentResults`、`getChildrenNullable`、`ConnectorTableStatistics.UNKNOWN`、`ConnectorColumnStatistics.UNKNOWN`。 + +**5）端到端回归：本批不需要。** 删掉的路径在生产上全是「默认值 / 恒空 / 恒 `Optional.empty()`」，唯一涉及引擎行为的是移除 `tryPushDownLimit()`，而它调用的接口八个连接器都没实现，返回值恒为空、恒不改 handle，删掉与保留在运行时完全等价。如果手上正好有集群，跑一遍外部表带 LIMIT 的既有回归用例作为额外确认即可（端到端用例需要本地集群，不构成本批的完成条件）。 + +## 七、风险与回退 + +- **主要风险是漏删引用导致编译失败**，而这在合并前一定会被第五条第 1 项的全反应堆含测试源编译抓住，不会漏到运行期。 +- **误删活代码的风险集中在两组同名符号上**（`getTableFormatType`、`getTableProperties`/`getSessionProperties`），5.3 第二类已逐个点名；动手时按**完整类名 + 方法签名**定位，不要按方法名 grep 后批量替换。 +- **`ConnectorMvccSnapshot` 的 `equals`/`hashCode` 语义会变**（少比两个字段）。因为生产侧从不设置这两个字段（恒为 `0` 与 `""`），任何两个生产对象在这两个字段上必然相等，去掉它们不改变任何一次比较的结果。它没有 Gson 持久化也不过 thrift，无兼容包袱。 +- **回退成本极低**：建议按上表的 10 个序号拆成 10 个提交（或至少把「`applyLimit` + `LimitApplicationResult`」和「`isExternal`」各自独立成一个提交）。任何一项出问题单独 revert，不牵连其它。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`： + - 「主题四：没有调用方或没有实现方的接口面」第 7.1 节（为什么死面比看起来严重）、第 7.2 节（本批的原始清单，注意其中 8 项经核实需要连带改连接器，已在 5.3 移出）、第 7.4 节（不做过时标注的理由与两条判断题）； + - 「主题四」第 7.3 节：需要连带改连接器的删除，下一批的范围； + - 附录 A.3「没有调用方或没有实现方的接口面」第 43–74

删掉，并连带删掉各连接器为它们写的实现和单测；其中建表的旧宽度重载不只是死代码，它的降级默认会**静默丢掉分区信息**，是留给下一个新连接器的陷阱。 + +## 二、背景：现在的代码是怎么写的 + +### 2.1 连接器级属性取得器 `ConnectorMetadata.getProperties` + +`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorMetadata.java:53-56`： + +```java + /** Returns connector-level properties. */ + default Map getProperties() { + return Collections.emptyMap(); + } +``` + +五个连接器覆写了它：`HiveConnectorMetadata.java:591`、`HudiConnectorMetadata.java:393`、`IcebergConnectorMetadata.java:806`、`JdbcConnectorMetadata.java:186`、`PaimonConnectorMetadata.java:452`（paimon 的覆写直接 `return Collections.emptyMap();`，即为满足接口而写的空覆写）。 + +引擎侧没有任何调用方。`fe-core` 主源里 `getProperties()` 的全部命中都属于**别的对象**：`ConnectorTableSchema`（`PluginDrivenExternalTable.java:521`）、`ConnectorDatabaseMetadata`（`PluginDrivenExternalDatabase.java:86`）、`CatalogProperty`、`CreateTableInfo` 等。名字撞车正是这一条难被发现的原因。 + +`ConnectorMetadata` 是**每语句/每次取用**构造出来的对象（`PluginDrivenMetadata.get(session, connector)`），而这个方法叫「连接器级属性」——挂错了层次。 + +### 2.2 分区值枚举 `ConnectorTableOps.listPartitionValues` + +`ConnectorTableOps.java:499`（上方注释写着 "Used by the `partition_values()` TVF and by column-distinct-value optimizations"）： + +```java + default List> listPartitionValues(ConnectorSession session, + ConnectorTableHandle handle, + List partitionColumns) { + return Collections.emptyList(); + } +``` + +三个连接器实现了它：`HudiConnectorMetadata.java:690`、`PaimonConnectorMetadata.java:1146`、`MaxComputeConnectorMetadata.java:300`。三份实现都在做同一件事：拿到分区列表，再按调用方给的列顺序把值投影成二维表。 + +而注释里说的两个用途，代码上都不经过它： + +- `partition_values()` 表函数：`MetadataGenerator.java:2035` → `PluginDrivenExternalTable.getNameToPartitionValues`（`PluginDrivenExternalTable.java:882`）→ **`metadata.listPartitions(...)`**（`:898-899`），FE 侧再按分区列名投影。 +- 分区系统表：`MetadataGenerator.dealPluginDrivenCatalog` → **`metadata.listPartitionNames(...)`**（`MetadataGenerator.java:1270`）。 + +也就是说「列分区」在公共接口上有三套（`listPartitions` / `listPartitionNames` / `listPartitionValues`），真正被引擎用的是前两套。 + +### 2.3 建表与删库各一个旧宽度重载 + +`ConnectorTableOps.java:222-228` 是窄形态，`:231-249` 是宽形态，宽形态的默认实现会**降级**到窄形态： + +```java + /** Creates a new table with the given schema and properties. */ + default void createTable(ConnectorSession session, + ConnectorTableSchema schema, Map properties) { + throw new DorisConnectorException("CREATE TABLE not supported"); + } + ... + default void createTable(ConnectorSession session, ConnectorCreateTableRequest request) { + ConnectorTableSchema schema = new ConnectorTableSchema( + request.getTableName(), request.getColumns(), null, request.getProperties()); + createTable(session, schema, request.getProperties()); // 分区/分桶/EXTERNAL/IF NOT EXISTS 就在这里蒸发 + } +``` + +`ConnectorSchemaOps.java:69-75` 与 `:76-86` 是同一形状：三参 `dropDatabase(session, dbName, ifExists)` 抛「不支持」，四参 `dropDatabase(..., force)` 默认丢掉 `force` 再转给三参。 + +实际实现与调用情况（已全仓核实）： + +| | 窄形态实现方 | 宽形态实现方 | 引擎调用的形态 | +|---|---|---|---| +| `createTable` | **零** | hive `:1569`、iceberg `:949`、paimon `:831`、maxcompute `:379` | 宽形态（`PluginDrivenExternalCatalog.java:455`） | +| `dropDatabase` | **零** | hive `:1537`、iceberg `:895`、paimon `:945`、maxcompute `:468` | 宽形态（`PluginDrivenExternalCatalog.java:553`） | + +### 2.4 主键：两套并存的机制，两套都没有读取方 + +- `ConnectorTableOps.getPrimaryKeys`（`:416-420`）：只有 jdbc 实现（`JdbcConnectorMetadata.java:259-261`，转给连接器内部的 `JdbcConnectorClient.getPrimaryKeys`）。引擎零调用，唯一调用点是 `fe-core` 的默认值测试 `FakeConnectorPluginTest.java:123`。 +- `ConnectorTableSchema.PRIMARY_KEYS_KEY`（`ConnectorTableSchema.java:80`，值为内部前缀 + `primary_keys`）：只有 paimon 写入（`PaimonConnectorMetadata.java:356-358`）。它同时被登记在 `RESERVED_CONTROL_KEYS`（`ConnectorTableSchema.java:118-120`）里，而 `fe-core` 会把这个集合里的键从 `SHOW CREATE TABLE` 的 `PROPERTIES(...)` 里**全部剥掉**——所以这条链路是「写进去，然后被删掉」，没有第三个消费者。 + +补充两个必须交代清楚的事实： + +1. **流式作业的主键不走这套接口**：它用的是 `fe-core` 自己的遗留 JDBC 客户端（`StreamingJobUtils.java:405` → `JdbcClient.java:426`），与连接器 SPI 无关，删除不影响它。 +2. **paimon 用户可见的主键属性另有一行**：`PaimonConnectorMetadata.java:341` 把 paimon 自己的 `primary-key` 选项写进表属性（这是 `SHOW CREATE TABLE` 要显示的东西），**这一行不动**。 + +## 三、为什么这是个问题 + +1. **死方法在向每个新连接器收税。** 一个新连接器作者读接口时要判断这四组要不要实现；`listPartitionValues` 还带一条「内层列表顺序必须与入参列顺序一致」的契约，三个连接器各自认真实现了一遍（注释里互相引用对方），产出的结果没有任何人读。 +2. **文档把人指向错的地方。** `listPartitionValues` 的注释说它服务 `partition_values()` 表函数，实际那条路走 `listPartitions`。照文档实现的连接器会发现「我实现了但功能不生效」，然后去引擎里找不到调用点。 +3. **建表的降级默认是一个正确性陷阱。** 它今天不触发（没人实现窄签名），但它是留给下一个连接器的地雷：只实现窄签名，`CREATE TABLE ... PARTITION BY ...` 会**建表成功且不报错**，分区、分桶、`EXTERNAL`、`IF NOT EXISTS` 全部静默丢失。删库那条同理：`force` 被默认丢掉后，`DROP DATABASE ... FORCE` 会变成非级联删除。 +4. **主键有两条并行通道且都没有读取方。** 新连接器作者要在「实现 `getPrimaryKeys`」和「写 `PRIMARY_KEYS_KEY`」之间猜，而两条都不通。 +5. **命名把层次搞错了。** 「连接器级属性」挂在每会话重建的元数据对象上，且与三个同名不同义的取得器混在一起。 + +### 顺带暴露的一个既存事实（本任务不修，需要拍板） + +hudi 连接器的缓存契约注释与单测把「`partition_values()` 表函数」标成走 `listPartitionValues` 并要求**绕过缓存**取最新（`HudiConnectorMetadata.java:692`、`HudiConnectorHmsCacheTest.java:38-45` 与 `:80-91`）。但真实的表函数路径走 `listPartitions`，而 hudi 的 `listPartitions` 是**读缓存**的（`HudiConnectorMetadata.java:671-674`）。所以 hudi 的 `partition_values()` 今天最多可能落后一个缓存 TTL —— 这是删除动作揭出来的既有行为，与本次删除无因果关系。本任务只负责**不要把错的映射留在注释和测试里**，是否要把这条路径改成取最新，另开一项、由人决定。 + +## 四、用一个最小例子说明 + +假设明天有人新增一个连接器 X，他读接口时看到两个 `createTable`，选了参数少的那个实现（这是最自然的选择：窄签名的文档是 "Creates a new table with the given schema and properties"，看不出它缺什么）。用户执行： + +```sql +CREATE TABLE x_catalog.db1.orders ( + id INT, + dt DATE +) +PARTITION BY LIST (dt) () +PROPERTIES ("file_format" = "parquet"); +``` + +| 用户写了什么 | 今天实际发生什么 | 应该发生什么 | +|---|---|---| +| 带 `PARTITION BY LIST (dt)` 建表 | 建表**成功**，返回 OK；远端表**没有分区**（宽形态默认把 `partitionSpec` 丢在半路），`SHOW PARTITIONS` 空 | 要么按分区建表，要么明确报错 | +| `IF NOT EXISTS` / `EXTERNAL` | 同样被静默丢弃：重复建表报「表已存在」而不是静默返回 | 按语义生效 | +| `DROP DATABASE db1 FORCE` | `force` 被默认丢弃 → 走非级联删除 → 库非空时远端报错，用户看到的是「删不掉」 | 按 `FORCE` 级联删除，或明确报「不支持」 | + +删掉窄签名之后，连接器 X 的作者在编译期就只看到一个入口，参数里明摆着 `partitionSpec` / `bucketSpec` / `isIfNotExists`；他不实现就会得到清晰的 `CREATE TABLE not supported`，而不是一张少了分区的表。 + +## 五、解决方案 + +### 5.1 目标状态 + +`fe-connector-api` 上四处删除 + 两处「把抛出点搬进保留的宽形态」： + +```java +// ConnectorMetadata：整段删除 getProperties（连注释） + +// ConnectorTableOps：删除 listPartitionValues、删除窄 createTable、删除 getPrimaryKeys； +// 宽形态自己抛出，不再降级： + /** + * Creates a table with full DDL semantics (partition, bucket, external, IF NOT EXISTS). + * Connectors that support CREATE TABLE override this. + * @throws DorisConnectorException if the connector cannot create tables + */ + default void createTable(ConnectorSession session, ConnectorCreateTableRequest request) { + throw new DorisConnectorException("CREATE TABLE not supported"); + } + +// ConnectorSchemaOps：删除三参 dropDatabase；四参自己抛出： + default void dropDatabase(ConnectorSession session, + String dbName, boolean ifExists, boolean force) { + throw new DorisConnectorException("DROP DATABASE not supported"); + } + +// ConnectorTableSchema：删除 PRIMARY_KEYS_KEY 常量，并从 RESERVED_CONTROL_KEYS 的列表里摘掉 +``` + +异常文案保持与今天**逐字一致**（`"CREATE TABLE not supported"` / `"DROP DATABASE not supported"`），这样既有的错误路径断言不会因为措辞而变化。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +|

注释里对它的引用（含「三个枚举钩子共享一份缓存」改为两个） | +| `fe-connector-hudi/.../HudiConnectorMetadata.java:689-706` | 删 `listPartitionValues`；同步修 `:709-711`、`:726` 注释（`collectPartitions` 的服务对象从三个变两个，且**不要**再把 `partition_values()` 写成走这条路） | +| `fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java:299-315` | 删 `listPartitionValues`；同步修 `MaxComputePartitionCache.java:41-43` 注释（三个消费者 → 两个） | +

重排等方言处理），不属于公共接口面。删掉 SPI 覆写后它们暂时没有调用者，是否清理属于 jdbc 连接器自己的事，另开一项。 +- **不要动任何连接器构造函数的签名。** `HiveConnectorMetadata` 有 31 处构造点，为消掉一个未用形参去改签名，风险远大于收益。 +- **不要动 paimon 写给用户看的 `primary-key`

`ConnectorScanRange` 的必须实现方法从 2 个降到 1 个。 + +## 二、背景：现在的代码是怎么写的 + +**枚举本体**：`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/scan/ConnectorScanRangeType.java:34`，4 个值 `FILE_SCAN` / `JDBC_SCAN` / `REMOTE_OLAP_SCAN` / `CUSTOM`。类注释（:20-32）声称： + +``` +Identifies the type of a ConnectorScanRange, which determines how BE processes the scan range. +Each type maps to a specific Thrift scan range variant in the execution layer. +``` + +**分片一侧的抽象方法**：`ConnectorScanRange.java:42-43` + +```java +/** Returns the scan range type, which determines BE processing. */ +ConnectorScanRangeType getRangeType(); +``` + +这是该接口仅有的两个抽象方法之一（另一个是 `getProperties()`，:112），其余十几个方法全部带默认实现。 + +**8 个连接器的实现，返回值完全一致**，无一例返回 `FILE_SCAN` 之外的值： + +| 连接器 | 位置 | 返回值 | +|---|---|---| +| es | `EsScanRange.java:75` | `FILE_SCAN` | +| hive | `HiveScanRange.java:82` | `FILE_SCAN` | +| hudi | `HudiScanRange.java:123` | `FILE_SCAN` | +| iceberg | `IcebergScanRange.java:154` | `FILE_SCAN` |

`TrinoScanRange.java:79` | `FILE_SCAN` | + +也就是说 `JDBC_SCAN`、`REMOTE_OLAP_SCAN`、`CUSTOM` 三个值零生产者——**连 jdbc 连接器自己都返回 `FILE_SCAN`**。 + +**提供方一侧还有一个同义方法**：`ConnectorScanPlanProvider.java:52` 的 `getScanRangeType()`，带默认值 `FILE_SCAN`，javadoc 说「引擎用它决定生成哪种 Thrift 分片结构」。它有 3 个覆写（`HiveScanPlanProvider.java:117`、`EsScanPlanProvider.java:95`、`JdbcScanPlanProvider.java:61`），三处都是逐字返回默认值 `FILE_SCAN`；引擎侧没有任何调用点。 + +**唯一的运行时痕迹**在公共模块自己的默认方法里，`ConnectorScanRange.java:182-194`： + +```java +default void populateRangeParams(TTableFormatFileDesc formatDesc, TFileRangeDesc rangeDesc) { + Map props = new HashMap<>(getProperties()); + props.put("connector_scan_range_type", getRangeType().name()); // :185 + props.put("connector_file_format", getFileFormat()); // :186 + ... + formatDesc.setJdbcParams(props); +} +``` + +引擎的调用点只有一处：`fe/fe-core/src/main/java/org/apache/doris/datasource/scan/PluginDrivenScanNode.java:1796`，它先按 `getTableFormatType()` 设好 `table_format_type`，然后把 Thrift 结构的构造整体委派给分片自己的 `populateRangeParams`。 + +**谁真的走这个默认实现**：8 个分片类里有 7 个覆写了 `populateRangeParams`（es/hive/hudi/iceberg/maxcompute/paimon/trino），且没有一个调用 `super.populateRangeParams`；只有 `JdbcScanRange` 吃默认实现。所以 `connector_scan_range_type` 这个键在生产中只会出现在 jdbc 分片的 `jdbc_params` 里。 + +**这个键在 BE 侧零命中**：`be/` 全树 grep `connector_scan_range_type` 无任何结果；jdbc 的 JNI 侧读取器 `fe/be-java-extensions/jdbc-scanner/.../JdbcJniScanner.java:109-147` 是逐键 `params.getOrDefault("jdbc_url", …)` 这样按名取值的，多余的键被直接忽略。而 `jdbc_params` 这张表本身是活的（`be/src/exec/scan/file_scanner.cpp:1160`、`be/src/format_v2/jni/jdbc_reader.cpp:65` 都在消费它），所以**只能删这一个键，不能删整个 `populateRangeParams` 默认方法**。 + +**4 个测试匿名类被迫实现它**（这是「交税」最直观的证据）：`fe/fe-core/src/test/java/org/apache/doris/datasource/scan/PluginDrivenScanNodeExplainStatsTest.java:58`、`fe/fe-core/src/test/java/org/apache/doris/datasource/split/PluginDrivenSplitPartitionValuesTest.java:46`、`fe/fe-core/src/test/java/org/apache/doris/datasource/split/PluginDrivenSplitWeightTest.java:47`、`fe/fe-connector/fe-connector-api/src/test/java/org/apache/doris/connector/api/scan/ConnectorScanRangeWeightDefaultsTest.java:38`。三个 fe-core 测试的注释直接写着「the two required methods」「the only two getters under test」——它们要测的是分片权重、分区值、EXPLAIN 统计，跟分片类型毫无关系。 + +## 三、为什么这是个问题 + +1. **必须实现，却没有出口。** 公共接口的抽象方法是对所有实现者的强制要求，代价必须由「引擎真的会读它」来偿付。这一处没有。新增一个连接器时，作者必须为它写一个 `return FILE_SCAN;`，而这个返回值走完全程后落在一个 BE 不认识的字符串键上。 +2. **文档是错的，会制造真实的排查浪费。** 枚举注释说「每个值对应一种 Thrift 分片结构」、`getScanRangeType()` 的注释说「引擎据此决定生成哪种结构」。实际决定 Thrift 形状的是两件别的事：分片自己覆写的 `populateRangeParams`（构造 iceberg/hudi/paimon/es 各自的 typed 结构），以及扫描节点级的格式类型（`PluginDrivenScanNode.getFileFormatType()`，:576-582，取自扫描节点属性表的 `file_format_type` 键）。按注释行事的人会去改枚举，然后发现改了不生效。 +3. **枚举值里带数据源名。** `JDBC_SCAN` 这种命名把具体数据源写进了本应中立的公共枚举，与「公共模块保持连接器中立」的方向相反；而它连一个生产者都没有。 +4. **它还在污染测试的表达。** 现有测试为了满足编译，被迫写出 `FILE_SCAN` 相关断言与注释，其中 `IcebergScanRangeTest.java:56-58`、`IcebergScanPlanProviderTest.java:174-175` 的 WHY 注释把错误的因果（「返回 JDBC_SCAN 会导致错误的 thrift 分片结构」）当作既定事实固化进了测试，反过来给后来人背书。 + +**用户可见后果**：没有。这不是正确性缺陷，唯一的运行时变化是 jdbc 分片的 `jdbc_params` 少一个没人读的键。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 X，它从远端 OLAP 系统读数据，我看到枚举里正好有 `REMOTE_OLAP_SCAN`： + +| 我写了什么 | 现在实际发生什么 | 应该发生什么 | +|---|---|---| +| `getRangeType()` 返回 `REMOTE_OLAP_SCAN`，期待引擎生成 OLAP 形状的 Thrift 分片 | 没有任何事发生：引擎从不读这个方法。分片形状仍由我是否覆写 `populateRangeParams` 决定；这个值最终只会（在我不覆写 `populateRangeParams` 时）以 `connector_scan_range_type=REMOTE_OLAP_SCAN` 落进 `jdbc_params`，BE 不认识这个键 | 根本不该有这个方法可写。我要控制 Thrift 形状，就覆写 `populateRangeParams`；要控制 BE 读取器，就用 `getTableFormatType()` 和扫描节点属性里的格式类型 | +| `getRangeType()` 返回 `FILE_SCAN`（照抄别人） | 同样什么都不发生 | 同上 | +| 我写测试想覆盖「分片权重默认值」这件事，必须先给匿名类补一个 `getRangeType()` | 每个测试匿名类都得写一遍这段与被测行为无关的代码 | 匿名类只需实现 `getProperties()` | + +三行的差别只有一处：删掉之后，**这个选择项不存在了**，没人会再花时间去选它、也没人会再因为「我改了枚举为什么不生效」去 debug。 + +## 五、解决方案 + +### 5.1 目标状态 + +`ConnectorScanRange` 只剩一个抽象方法： + +```java +public interface ConnectorScanRange extends Serializable { + /** Returns additional connector-specific properties. */ + Map getProperties(); + // …其余全部带默认实现，包括 populateRangeParams +} +``` + +`populateRangeParams` 的默认实现去掉分片类型键（其余不动）： + +```java +default void populateRangeParams(TTableFormatFileDesc formatDesc, TFileRangeDesc rangeDesc) { + Map props = new HashMap<>(getProperties()); + props.put("connector_file_format", getFileFormat()); + // partition.* 键照旧 + formatDesc.setJdbcParams(props); +} +``` + +`ConnectorScanPlanProvider` 不再有 `getScanRangeType()`；`ConnectorScanRangeType.java` 整个文件删除。 + +类注释同步据实改写：`ConnectorScanRange` 的类 javadoc（:33-35）现在说「range type 决定引擎如何转换成 Thrift 结构」，改成「连接器通过覆写 `populateRangeParams` 决定自己的 Thrift 形状，`getTableFormatType()` 决定 BE 侧读取器」。 + +### 5.2 改动清单 + +| 文件 | 位置 | 做什么 | +|---|---|---| +| `fe-connector-api/.../scan/ConnectorScanRangeType.java` | 整个文件 | 删除 | +|

+### 5.3 明确不要顺手做的事 + +- **不要把 `getProperties()` 降成带默认实现（返回空表）。** 删掉分片类型方法后，`getProperties()` 成了唯一的抽象方法，看上去很想顺手一起默认化。实测收益很小：8 个连接器里只有 iceberg 返回空表（`IcebergScanRange.java:316-320`，它的载荷是 typed 字段），另外 7 个都有真实内容；只有 iceberg 加 4 个测试匿名类能因此少写几行。代价是明确的：`JdbcScanRange` 是唯一走默认 `populateRangeParams` 的生产实现，它的整张属性表就是 BE jdbc 读取器的入参，一旦 `getProperties()` 可以不实现，将来某个连接器忘了实现就会静默地把空表发给 BE（表现为运行期缺 `jdbc_url` 之类，而不是编译期报错）。这一项如果要做，应当作为独立决策，不要塞进本任务。 +- **不要动 `getFileFormat()` 本身**，也不要删 `connector_file_format` 键。本任务只改它 javadoc 里对被删枚举的引用。这个方法的出口是否充足是另一条独立结论（见调研报告附录 C.3 第 1 条 —— 格式与读取机制混在一个字段），牵动扫描级格式类型这条已知风险线，不适合在一次删除里带过。 +- **不要删 `populateRangeParams` 默认方法**，也不要删 `formatDesc.setJdbcParams(props)`。`jdbc_params` 在 BE 侧是活链路。 +- **不要顺手改 `getTableFormatType()` 的默认值 `"plugin_driven"`**，那是 BE 读取器路由的活值。 +- **不要去改 `plan-doc/` 下的历史文档**里对这个枚举的描述（`plan-doc/tasks/designs/` 里的两份设计稿、以及同日的另一份评审文档）。历史文档的勘误由 25 号任务统一处理。 +- **不要为「不许再出现分片类型枚举」加 shell 或正则构建门禁。** 删除后类不存在，编译本身就是最强门禁。 + +## 六、怎么验证 + +1. **新增一条单测钉住唯一的运行时变化**（放 `fe-connector-jdbc` 的 `JdbcScanRangeAndPropertiesTest`，因为 jdbc 是默认 `populateRangeParams` 的唯一生产消费者，而目前**整个仓库没有任何测试覆盖这个默认实现**）： + - 构造一个带 `querySql/jdbcUrl/jdbcUser` 的 `JdbcScanRange`，调用 `populateRangeParams(new TTableFormatFileDesc(), new TFileRangeDesc())`； + - 断言 `formatDesc.getJdbcParams()` 仍然包含 `query_sql`、`jdbc_url`、`jdbc_user` 这几个 BE 侧真实消费的键（WHY：这张表就是 BE jdbc 读取器的入参，删键的改动绝不能碰到它）； + - 断言这张表**不含** `connector_scan_range_type` 键（WHY：这个键 BE 与 JNI 侧都不读，本次删除的意图就是让它消失；变异验证：把那行 `props.put` 加回去 → 该断言变红）。 +2. **零残留 grep**（存在性检查，可直接跑）： + `grep -rn "ConnectorScanRangeType\|getRangeType\|getScanRangeType\|connector_scan_range_type" --include=*.java fe/` 应为 0 命中。 +3. **编译门禁（最强单一信号）**：全反应堆**含测试源**编译，禁用任何跳过测试编译的参数—— + `mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile` + 这一步同时覆盖了「删接口方法后所有实现类与匿名类都清理干净」和「`import` 未残留（checkstyle 扫测试源）」两件事。 +4. **跑受影响模块的单测**，必须显式关掉 maven build cache（否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的）： + `mvn -f .../fe/pom.xml -Dmaven.build.cache.enabled=false -pl fe-connector/fe-connector-api,fe-connector/fe-connector-jdbc,fe-connector/fe-connector-es,fe-connector/fe-connector-iceberg test` + 另外单独跑 fe-core 的三个受影响测试类（`PluginDrivenSplitWeightTest`、`PluginDrivenSplitPartitionValuesTest`、`PluginDrivenScanNodeExplainStatsTest`）。 +5. **端到端回归**：不需要新增用例。这个改动唯一的有线格式变化是 jdbc 分片的 `jdbc_params` 少一个键，已被上面的单测钉住；如果手上正好有环境，跑一遍任意 jdbc 目录的查询回归即可（jdbc 是唯一走默认路径的连接器），其余连接器的分片路径字节不变。 + +## 七、风险与回退 + +- **风险点只有一处**：`populateRangeParams` 默认实现里的键删除。若误删同一段里的 `connector_file_format` 或 `setJdbcParams` 调用，会打断 jdbc 的活链路，表现为 jdbc 目录查询在 BE 侧拿不到连接参数而失败。六（1）的断言正是为此设置。 +- **不涉及 Gson 持久化**：`ConnectorScanRangeType` 没有注册进任何 `RuntimeTypeAdapterFactory`，也不在任何元数据镜像里；`ConnectorScanRange` 虽然声明 `extends Serializable`，但仓库里没有任何地方对它做 Java 序列化（`fe-core` 的 datasource 包下无 `ObjectOutputStream` / `SerializationUtils` 命中），分片对象只在单次查询的规划期内存活。因此删方法不存在兼容性负担。 +- **不涉及 Thrift 有线结构**：删除的只是一个字符串键，没有改动任何 `.thrift` 定义。 +- **插件是独立打包的**：连接器与公共模块必须同批构建、同批部署。混用（老连接器包 + 新公共模块）会在类加载期报 `NoSuchMethodError` / `NoClassDefFoundError`。本仓库的连接器与 `fe-core` 一起构建发布，正常流程下不会出现混用；但如果有人手工替换单个插件 zip，需要重新打包全部连接器。 +- **回退**：本任务是纯删除 + 一条新测试，`git revert` 单个提交即可完整回到原状，无数据面残留。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`：附录 A.3 第 49、50、51 条 —— 分片类型枚举与强制方法零消费者，其中第 50、51 条的「复核收窄」记录了严重度为中而非高的理由，以及「BE 侧零命中」的证据；附录 C.3 第 1 条 —— `getFileFormat()` 默认值把格式与读取机制混在一起，是独立结论（本任务明确不动）。 +- 同目录 `README.md` 第三优先级小节说明了这一批删除的判据：「死接口的成本不是占空间，是逼着每个新连接器为不存在的出口交税」。 +- 11 号任务（第一批死接口面删除）同样改动 `fe-connector-api` 的 scan 包，建议排在其后。 +- 关于扫描级格式类型为什么危险（本任务刻意不碰 `getFileFormat()` 的原因）：`PluginDrivenScanNode.getFileFormatType()`（`:576-582`）在分片之前就决定了 BE 走哪一代文件读取器，发错值会把整个连接器钉在旧读取器上。 diff --git

行）、`invalidatePartition`（336 行）。引擎侧实测 **17 处**调用（调研报告里写的 16 处漏了一处跨行书写的调用），分布在三个文件： + +| 调用方文件 | 处数 | +|---|---| +| `fe/fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenExternalCatalog.java` | 10（289、464、562、616、642、686、687、766、779、792 行） | +| `fe/fe-core/src/main/java/org/apache/doris/catalog/RefreshManager.java` | 5（124、202、203、248、288 行） | +| `fe/fe-core/src/main/java/org/apache/doris/datasource/CatalogMgr.java` | 2（818、853 行） | + +这一套的分区参数是**分区名**。`Connector.java:333-334` 的契约写得很明确：`canonical partition names ("col=val/.../colN=valN")`；连接器侧有对应测试，`fe/fe-connector/fe-connector-hive/src/test/java/org/apache/doris/connector/hive/HiveConnectorPartitionViewCacheTest.java:124` 传的就是 `"dt=2024-01-01"`。 + +**方向二（死的）：连接器通知引擎丢弃引擎的缓存。** +`fe/fe-connector/fe-connector-spi/src/main/java/org/apache/doris/connector/spi/ConnectorMetaInvalidator.java:32` 定义了一个 5 方法接口（`invalidateAll` / `invalidateDatabase` / `invalidateTable` / `invalidatePartition` / `invalidateStatistics`，全是空 default，并带一个 `NOOP` 常量）。入口是 `fe/fe-connector/fe-connector-spi/src/main/java/org/apache/doris/connector/spi/ConnectorContext.java:109` 的 `getMetaInvalidator()`，默认返回 `NOOP`。引擎侧实现是 `fe/fe-core/src/main/java/org/apache/doris/connector/ExternalMetaCacheInvalidator.java:34`，由 `fe/fe-core/src/main/java/org/apache/doris/connector/DefaultConnectorContext.java:168-171` 返回。 + +这一套的分区参数是**分区列值**（`ConnectorMetaInvalidator.java:48-50` 的注释：`["2024", "01"]`）。 + +**实测调用方情况**：全仓库提到 `MetaInvalidator` 的只有 9 个文件——接口自身、`ConnectorContext`、`DefaultConnectorContext`、fe-core 的桥实现 `ExternalMetaCacheInvalidator`、fe-core 的 `FakeConnectorPluginTest`（断言默认返回 `NOOP`）、iceberg/paimon 两个上下文包装类里的一行转发、iceberg 的测试替身 `RecordingConnectorContext`、以及 `IcebergProcedureOpsTest:241` 注释里的一次提及。**零个连接器生产代码调用它。** + +**真正在跑的是拉模型。** 外部元存储的变更由引擎轮询：`fe/fe-core/src/main/java/org/apache/doris/datasource/MetastoreEventSyncDriver.java:164` 调连接器的 `pollOnce` 拿一批中立的变更描述，`applyDescriptors`（202 行）由引擎自己作用到对象图和缓存上；需要丢连接器缓存时再走上面方向一的 17 处调用。连接器只负责「取事件 + 解析」，不负责通知谁去丢缓存。 + +iceberg 的测试已经把这段历史钉住了。`fe/fe-connector/fe-connector-iceberg/src/test/java/org/apache/doris/connector/iceberg/IcebergProcedureOpsTest.java:56-61` 的类注释写：失效是引擎的责任，dispatch 不得失效任何缓存，`ctx.invalidatedTables` 在每次分派后都必须是空的，「非空就意味着**已被移除的**连接器侧通知又被加回来了」；对应断言有 7 处（167、242、271、290、324、349、370 行）。 + +## 三、为什么这是个问题 + +**第一，引擎侧履行不了这个接口承诺的语义**，两个方法名不副实，且这一点是写在代码注释里的既知事实： + +- `ExternalMetaCacheInvalidator.java:60-69`：SPI 传来的是分区**值**，而引擎的分区缓存按分区**名**索引，从值还原名需要分区列名而 SPI 没有携带 —— 于是降级成整表失效，注释自认 `correct but over-broad`。 +- `ExternalMetaCacheInvalidator.java:71-77`：`invalidateStatistics` 是**空方法**，因为引擎没有「只丢统计不丢 schema」的入口（行数缓存按 id 而非名索引），调 `invalidateTable` 会违反接口注释里「without dropping schema cache」的承诺。 + +也就是说：5 个方法里有 1 个是骗人的空操作、1 个的作用域比声明的粗一整个数量级。这两处的行为还各被一个单测钉住（`ExternalMetaCacheInvalidatorTest.java:76` 与 `:91`），于是「已知做不到」被固化成了「受保护的既定行为」。 + +**第二，同一件事的两套词汇互相冲突，是给下一个连接器作者埋的坑。** 名字撞、参数语义还相反： + +| | 引擎 → 连接器（活的） | 连接器 → 引擎（死的） | +|---|---|---| +| 按库失效 | `Connector.invalidateDb(dbName)` | `ConnectorMetaInvalidator.invalidateDatabase(dbName)` | +| 按分区失效的第三个参数 | 分区**名**列表 `["dt=2024-01-01"]` | 分区**值**列表 `["2024", "01"]` | + +一个新连接器作者看到 `ConnectorContext` 上挂着 `getMetaInvalidator()`，很自然会以为「我发现远端变了就该调它」，然后写出一段编译通过、运行不报错、但按分区失效实际把整张表的缓存都掀掉、按统计失效什么都不做的代码。 + +**第三，这是公共接口上的死面积。** `ConnectorContext` 是每个连接器都要面对的引擎服务门面（今天 19 个方法），其中一个方法通向一个完全没人用的方向。删掉它对任何在跑的功能都是零影响。 + +用户能不能观察到错误行为？今天不能——因为没人调用。这不是正确性缺陷，是「留着就会变成正确性缺陷」的陷阱。 + +## 四、用一个最小例子说明 + +场景：有人在远端 Hive 元存储上执行 + +```sql +ALTER TABLE sales.orders ADD PARTITION (year='2024', month='01'); +``` + +Doris 侧需要让缓存反映这个变化。同一个需求，两条路的实际结果： + +| 连接器想表达的意思 | 走死掉的推模型今天实际发生什么 | 走活的拉模型（保留的那一套）实际发生什么 | +|---|---|---| +| 「`sales.orders` 多了一个分区 `year=2024/month=01`，只丢这个分区」 | 连接器调 `context.getMetaInvalidator().invalidatePartition("sales", "orders", ["2024","01"])` → 引擎拿到的是列值、缓存按分区名索引 → **整张表的缓存全丢** | 引擎轮询到变更后自己调 `connector.invalidatePartition("sales", "orders", ["year=2024/month=01"])` → **按分区名精确失效** | +| 「这张表的统计过期了，只丢统计、别丢 schema」 | 连接器调 `invalidateStatistics("sales","orders")` → **什么都不发生**（空方法），连接器却以为已经生效 | 这条路今天不存在；需要时走正常的刷新路径 | + +删掉左边一列，「失效」就只剩右边一套词汇：分区一律用分区名，方向一律是引擎调连接器。 + +## 五、解决方案 + +### 5.1 目标状态 + +- `fe-connector-spi` 里不再有 `ConnectorMetaInvalidator` 这个类型。 +- `ConnectorContext` 的方法数从 19 降到 18，不再有 `getMetaInvalidator()`： + + ```java + // 删除下面整块（含其上方 6 行 javadoc） + // default ConnectorMetaInvalidator getMetaInvalidator() { + // return ConnectorMetaInvalidator.NOOP; + // } + ``` + +- `fe-core` 少一个类 `ExternalMetaCacheInvalidator` 与它的单测（fe-core 只减不增，符合当前阶段纪律）。 +- 失效相关的公共接口只剩 `Connector` 上那 4 个方法（签名不动）： + + ```java + default void invalidateTable(String dbName, String tableName) { } + default void invalidateAll() { } + default void invalidateDb(String dbName) { } + default void invalidatePartition(String dbName, String tableName, List partitionNames) { } + ``` + +### 5.2 改动清单 + +| 文件 | 动作

处断言原本证明的是「连接器没有走推模型通知引擎」。删掉这套 SPI 之后，连接器**在类型层面就不存在**这条通道了，断言的失败条件不可能再出现——留一个永远不会红的断言比删掉它更糟（不可能失败的测试没有意义）。它保护的意图改由「代码里没有这个接口」结构性保证，设计意图则留在类注释里。 + +### 5.3 明确不要顺手做的事 + +1. **不要把 `Connector.invalidateDb` 改名成 `invalidateDatabase`。** 推模型删掉后名字冲突自动消失，剩下的单套名字叫什么已经不重要；改名要动 17 处调用点，纯搅动，且属于另一个「命名统一」议题。 +2. **不要动 `ExternalMetaCacheMgr`。** 它的 `invalidateCatalog` / `invalidateDb` / `invalidateTable` 都另有引擎自身的调用方（例如 `fe/fe-core/src/main/java/org/apache/doris/datasource/ExternalCatalog.java:690` 与 `.../ExternalDatabase.java:131`），删掉桥不会留下孤儿方法，也就不需要连带清理。 +3. **不要顺手补「只丢统计不丢 schema」的入口。** 那是一个独立的功能缺口，而且要往 fe-core 加数据源相关代码，违反当前阶段 fe-core 只出不进的纪律。谁真需要它，另开任务。 +4. **不要顺手给 iceberg/paimon 的包装类补别的缺失转发。** 实测 paimon 的包装类少转发 `newStorageUriNormalizer` 与 `getFileSystem`，这是编号 06 那项任务的范围。 +5. **不要顺手给 `fe-connector-api` / `fe-connector-spi` 写模块边界文档。** 那是同一章调研里的另一条建议，与本任务解耦。 +6. **不要在 iceberg 测试里保留「改写版」断言去模拟推模型**（比如自己造一个记录器再断言它是空的）。那是给已删除的机制立纪念碑。 + +**与编号 06 的顺序**：两项都改 iceberg/paimon 的 `TcclPinningConnectorContext.java`，但改的是不同方法块，文本不相邻。建议**先做本任务**（纯删，让包装类需要转发的方法先少一个），再做 06 补齐剩余转发；若已先做了 06，本任务照删本方法块即可，不需要回滚 06 的改动。合批也可以，但要在同一个提交里说明两件事。 + +## 六、怎么验证 + +1. **编译门禁（本任务最强的单一信号）**：删类型的验证本质上是符号级验证——任何漏改的引用都编译失败。跑全反应堆、**含测试源**： + + ```bash + mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T1C test-compile + ``` + + 禁止使用跳过测试编译的参数。要求 `BUILD SUCCESS`。 + +2. **删净反查**： + + ```bash + grep -rn "MetaInvalidator" /mnt/disk1/yy/git/wt-catalog-spi --include=*.java + ``` + + 期望零命中（`plan-doc/` 下的历史记录文档命中属正常，不要去改历史记录）。 + +3. **受影响单测（必须禁用 maven build cache，否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的）**： + - `FakeConnectorPluginTest`（fe-core，删掉一个 `@Test`，其余必须仍全绿） + - iceberg 的 `IcebergProcedureOpsTest`、`TcclPinningConnectorContextTest` + - paimon 的 `TcclPinningConnectorContextTest` + +4. **确认活的那一套没被牵连**：`HiveConnectorPartitionViewCacheTest.invalidatePartitionDropsTheWholeTablesCachedView`（`HiveConnectorPartitionViewCacheTest.java:105`）必须仍绿——它验证的是保留下来的方向（引擎调连接器、参数是分区名）。 + +5. **不需要变异验证，也不需要端到端回归**：删的是零生产调用方的接口面，运行时行为不变；没有任何 SQL 路径的行为会改变，因此不新增 groovy 回归。checkstyle 会扫测试源，注意删 import 后不要留下未使用 import。 + +## 七、风险与回退 + +风险低。三条可能的意外与应对： + +- **担心「以后 HMS 事件管线搬进连接器时还需要它」**：不成立。事件管线已经按拉模型落地（`MetastoreEventSyncDriver` + 连接器的 `pollOnce` + 中立变更描述），而且 iceberg 测试注释明确记载连接器侧通知是**被有意移除**的。真需要推模型时，那时的需求会带着「分区名 vs 分区值」「统计缓存入口」这些今天缺失的信息一起来，重新设计比留一个错的空壳更好。早期计划文档（`plan-doc/00-connector-migration-master-plan.md`、`plan-doc/01-spi-extensions-rfc.md`、`plan-doc/decisions-log.md` 的相关决策条目）里还写着「事件管线通过这个接口回调」，那是已被实现推翻的旧决策；本任务落地后应在这些文档里补一句作废说明，但**不要**改写历史进度记录。 +- **担心外部实现者**：这是内部接口，仓库外没有实现者；不做过时标注、直接删（与本轮整治的既定节奏一致）。 +- **回退**：改动全在一个提交内且是纯删除，`git revert` 即可完整恢复，无数据/持久化影响（这些类型不参与 Gson 持久化、也不参与 thrift 有线格式）。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` + - 第十三节「`api` 与 `spi` 两个模块的边界说不清」——该节末尾「缓存失效这件事被这个边界切成了两半，而且方向相反」那段给出了两套方向的对照，同节建议第 2 条就是删掉这套死的推模型； + - 第 7.3 节「需要连带改连接器的删除」——本条在表格里，连带改动写的是「删 iceberg / paimon 两个包装类的转发与相关测试替身」； + - 附录 A 第 78、79 两条原始发现——失效有两套并存机制、且两套方向相反的词汇，其中 78 被复核收窄为「构成零生产调用方的死 SPI 表面」； + - 附录 C.1「两轮独立结论高度重叠」——在「本文更准的地方」清单里确认结论是「应删而不是改名」。 +- 相关任务：编号 06《补齐上下文包装类的转发缺口》（改同两个文件，顺序见 5.3）。 +- 旧决策出处（本任务作废其结论）：`plan-doc/decisions-log.md` 的「HMS event pipeline 放 fe-connector-hms，通过 ConnectorMetaInvalidator 回调」条目、`plan-doc/01-spi-extensions-rfc.md` 第 6 节。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/15-remove-catalog-type-allowlist.md

里的七个类型名的集合；不在这张集合里的类型，哪怕插件已经装好、已经被插件加载器成功装配、启动日志里都能看到它，`CREATE CATALOG` 依然会失败。本任务删掉这张集合，把它承担的唯一一件真实职责（排除 hudi）上移成连接器自己的一句声明，让「注册了插件就能被路由到」这句承诺在代码上第一次成立。 + +## 二、背景：现在的代码是怎么写的 + +### 白名单本体 + +`fe/fe-core/src/main/java/org/apache/doris/datasource/CatalogFactory.java:56-57`： + +```java +private static final Set SPI_READY_TYPES = + ImmutableSet.of("jdbc", "es", "trino-connector", "max_compute", "paimon", "iceberg", "hms"); +``` + +它上面有一段 9 行的注释（`:47-55`），说明了两件事：这七个类型走插件（SPI）路径，别的类型掉到下面的内建 `switch`；以及**「不要把 hudi 加进这个集合」**。 + +### 判定点 + +同文件 `createCatalog`（`:76`）里，`catalogType` 从 `type` 属性（或 resource）解析出来后（`:79-96`），有三段判定： + +```java +Connector spiConnector = null; +if (SPI_READY_TYPES.contains(catalogType)) { // :110 第一次查集合 + spiConnector = ConnectorFactory.createConnector( + catalogType, props, new DefaultConnectorContext(name, catalogId)); +} +if (spiConnector != null) { // :114 + catalog = new PluginDrivenExternalCatalog(...); // :117 +} else if (SPI_READY_TYPES.contains(catalogType)) { // :119 第二次查集合 + if (isReplay) { + catalog = new PluginDrivenExternalCatalog(..., null); // :128 降级注册 + } else { + throw new DdlException("No connector plugin

// :143 + case "doris": ... // :146 + case "test": ... // :153（仅单测） + default: throw new DdlException("Unknown catalog type: " + catalogType); // :157 + } +} +``` + +所以现在的形状是：**先查集合 → 集合里才问插件 → 集合里但没插件就（建目录时）报错或（重放时）降级 → 集合外一律落到内建 `switch`，最后抛「Unknown catalog type」**。 + +### 插件侧的自描述发现机制其实已经完备 + +`fe/fe-connector/fe-connector-spi/src/main/java/org/apache/doris/connector/spi/ConnectorProvider.java`： + +- `:46` `String getType()` —— 连接器自报类型名，注释写着「对应 `CREATE CATALOG` 里的 `type` 属性」。 +- `:52-54` `default boolean supports(String catalogType, Map properties)` —— 默认按类型名比较，但**留了按属性判定的口子**。 + +`fe/fe-core/src/main/java/org/apache/doris/connector/ConnectorPluginManager.java:126-144` 的 `createConnector` 就是照这个机制做的：遍历已注册 provider，第一个 `supports(...)` 返回 true 的胜出，检查 API 版本后建连接器；一个都不匹配就返回 `null`。也就是说**动态分派早就有了，白名单是叠在它上面的一层编译期硬门禁**。 + +仓库里一共 8 个 provider（各连接器模块的 `META-INF/services/org.apache.doris.connector.spi.ConnectorProvider` 都已核实）：`hms`、`iceberg`、`paimon`、`jdbc`、`es`、`max_compute`、`trino-connector`、`hudi`。白名单正好等于「这 8 个减去 hudi」。**换句话说，白名单今天的全部效果就是两件事：排除 hudi，以及挡住所有第三方连接器。** + +### hudi 为什么必须被排除 + +`fe/fe-connector/fe-connector-hudi/src/main/java/org/apache/doris/connector/hudi/HudiConnectorProvider.java:31-39` 的类注释已经把理由写透了：`"hudi"` 是一个**只用于兄弟连接器查找的类型串，不是用户可见的目录类型**。一张 hudi 表寄生在 Hive 元存储目录上，运行时由 hms 网关通过 `ConnectorContext.createSiblingConnector("hudi", ...)` 构造成内嵌兄弟连接器；`fe-core` 没有、也不该有 hudi 的目录类。真给 `type=hudi` 建一个独立目录，就会造出一个没有引擎侧目录语义支撑的空壳。 + +兄弟连接器走的是另一条门：`fe/fe-core/src/main/java/org/apache/doris/connector/DefaultConnectorContext.java:174-183` 的 `createSiblingConnector` 直接调 `ConnectorFactory.createConnector(...)`，**根本不经过 `CatalogFactory` 的白名单**。这条门必须保持能查到 hudi。 + +### 类型名唯一性只写在文档里，没人保证 +

"type" = "acme-lake"` 依然得到「Unknown catalog type: acme-lake」。要让它能用，唯一办法是改 `CatalogFactory.java:57` 那一行、重新编译并发布整个 FE —— 这恰好是插件化想消掉的事情。这是整轮整治里唯一能真正兑现这条承诺的改动。 + +**第二，它让 `supports(catalogType, properties)` 这个能力事实上不可用。** 按属性（而不是仅按类型名）分派的口子留在了公共接口上，但因为外层先按类型名过一遍白名单，任何「类型名不在名单里、只有属性能识别」的分派都不可能发生。目前全仓 0 个连接器覆写 `supports` —— 不是因为没人需要，是因为覆写了也不会被调用。删掉白名单，这个能力才第一次真正接通。 + +**第三，它顺带造成一个现存缺陷：不认识的目录类型会让 FE 起不来。**（这是本任务顺带修掉的净改善） +`CatalogMgr.replayCreateCatalog`（`fe/fe-core/src/main/java/org/apache/doris/datasource/CatalogMgr.java:546-549`）在编辑日志重放时调 `CatalogFactory.createFromLog`。一旦它抛异常，`fe/fe-core/src/main/java/org/apache/doris/persist/EditLog.java:1150-1154` 的 `OP_CREATE_CATALOG` 分支把异常交给 `:1524-1538` 的兜底 `catch`，那里除非该操作码被列进 `Config.skip_operation_types_on_replay_exception`（`fe/fe-common/src/main/java/org/apache/doris/common/Config.java:1311`，默认 `{-1, -1}` 即空），就直接 `System.exit(-1)`。 + +现在的代码只对**白名单内**的类型做了重放降级保护（`:119-129`）。白名单外的类型在重放时会走到 `:157` 抛异常 → FE 进程退出。用户观察到的现象是：**一次本来只该让某个目录不可用的问题，变成整个 FE 起不来**，而且日志里只有一行「Unknown catalog type」。 + +顺带说明：从元数据镜像恢复的那条路径**已经**没有这个问题 —— 镜像里目录是 Gson 反序列化成 `PluginDrivenExternalCatalog`（`fe/fe-core/src/main/java/org/apache/doris/persist/gson/GsonUtils.java:358-407`），连接器是首次访问时由 `PluginDrivenExternalCatalog.createConnectorFromProperties()`（`:192-205`）惰性创建的，那里**不查白名单**。所以本任务的另一个价值是把两条恢复路径的口径拉齐：第三方连接器的目录一旦能建出来，重启后无需任何 Gson 改动就能正确恢复（`clazz` 就是 `PluginDrivenExternalCatalog`）。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 `acme-lake`，插件已装好并被成功加载。 + +```sql +CREATE CATALOG my_lake PROPERTIES ("type" = "acme-lake", "acme.uri" = "http://acme:8080"); +``` + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +|---|---|---| +| 上面这条 `CREATE CATALOG` | 报错 `Unknown catalog type: acme-lake`。引擎连插件都没问 —— `"acme-lake"` 不在 `CatalogFactory` 那七个字符串里，直接掉进内建 `switch` 的 `default` | 引擎向已注册的 provider 逐个问 `supports("acme-lake", props)`，`AcmeConnectorProvider` 认领，建出 `PluginDrivenExternalCatalog` | +| 同一条语句，但插件**没**装 | 报错 `Unknown catalog type: acme-lake`（看不出是插件缺失还是类型写错） | 报错「没有插件认领类型 `acme-lake`，当前已注册类型：\[hms, iceberg, ...\]」 | +| 目录已建好，此后重启 FE，且这条建目录日志还没被 checkpoint 掉，而插件被运维误删 | 重放抛异常 → `System.exit(-1)`，**FE 起不来** | 降级注册该目录；只有真去访问它时才报「未找到插件，请确认插件已安装」 | +| `CREATE CATALOG h PROPERTIES ("type" = "hudi")` | 报错（白名单里没有 hudi）—— 这是**正确**行为，必须保住 | 依然报错。理由不再是「不在白名单里」，而是 hudi 的 provider 自己声明了 `isStandaloneCatalogType() == false` | + +「我今天必须动哪些文件」这个问题的答案就是这张表的第一行：**`fe/fe-core/.../CatalogFactory.java` 一行，然后重编译发布 FE**。本任务之后答案变成：一个文件都不用动。 + +## 五、解决方案 + +### 5.1 目标状态 + +**（1）连接器自己声明「我能不能作为一个独立目录出现」**，在 `fe-connector-spi` 的 `ConnectorProvider` 上加一个带默认实现的方法（默认 true，对齐仓库既有的 `supportsXxx()` opt-in 惯例；这里语义是「默认允许、少数否认」，所以默认值取 true）： + +```java +/** + * 本 provider 的类型能否作为一个独立目录出现在 CREATE CATALOG 的 type 属性里。 + * + * 返回 false 表示这个连接器只以内嵌兄弟身份存在（由另一个连接器通过 + * ConnectorContext.createSiblingConnector 构造并持有），引擎不会为它建独立目录； + * 它仍然正常参与服务发现与兄弟查找。默认 true。 + */ +default boolean isStandaloneCatalogType() { + return true; +} +``` + +**（2）区分两条查询入口。** 兄弟连接器查找**必须**仍然能查到非独立类型，所以这个开关只能作用在「建独立目录」这条路径上，绝不能塞进 `ConnectorPluginManager.createConnector`： + +| 入口 | 用途 | 是否过滤非独立类型 | +|---|---|---| +| `ConnectorPluginManager.createConnector` / `ConnectorFactory.createConnector` | 兄弟连接器查找（`DefaultConnectorContext.createSiblingConnector`） | **否**（hudi 靠它） | +| 新增 `createStandaloneCatalogConnector`（两个类上各一个同名入口） | 建独立目录 | 是 | + +实现上让两个入口共用一个私有方法、只差一个 `standaloneOnly` 布尔量即可，不要复制遍历逻辑。 + +**（3）`CatalogFactory.createCatalog` 改成三段式**，删掉 `SPI_READY_TYPES`： + +``` +① 无条件问插件：createStandaloneCatalogConnector(catalogType, props, ctx) + 命中 -> PluginDrivenExternalCatalog(带连接器) +② 没命中 -> 问引擎内建类型（lakesoul / doris / test 这个 switch 原样保留） + 命中 -> 原样处理 +③ 都没命中： + isReplay == true -> 降级注册 PluginDrivenExternalCatalog(connector = null)，打 WARN + isReplay == false -> DdlException，文案说明「没有插件认领该类型」并列出 ConnectorFactory.getRegisteredTypes() +``` + +第 ③ 步就是白名单内那段降级逻辑（`:119-135`）的去白名单版本：**降级/报错的判据从「类型在名单里」变成「引擎也不认识它」**。降级目录首次访问时的报错文案不用改，`PluginDrivenExternalCatalog.initLocalObjectsImpl` 已有（`:162-165`）：`No ConnectorProvider found for plugin-driven catalog: , type: .

为了能直接测到，建议把「登记一个已发现的 provider」抽成一个包内可见的小方法，让两个批次都调它，测试直接打这个方法 —— 不要为了测试去伪造 `META-INF/services` 文件。 +- 一条断言保住 `registerProvider` 的遮蔽语义：先 `loadPlugins` 装一个 `"iceberg"`，再 `registerProvider` 一个同名的，后者必须胜出且不报冲突（多个既有测试依赖这条，见 `DefaultConnectorContextSiblingTest.java:77`）。 + +**（3）单元测试：重放不再让 FE 退出**（扩 `fe/fe-core/src/test/java/org/apache/doris/datasource/ExternalCatalogTest.java`，那里已有现成的 `registerCatalogViaReplay` 私有助手，`:169-177`） + +- 用一个引擎和插件都不认识的类型（例如 `"acme-lake"`）走 `mgr.replayCreateCatalog`：**必须不抛异常**，且目录能在 `mgr` 里查到。断言注释里要写清 WHY：这条路径上抛异常会经由 `EditLog` 的兜底 `catch` 走到 `System.exit(-1)`，代价是整个 FE 起不来。 +- 同一个目录上触发一次会走到 `makeSureInitialized` 的访问，断言报错文案含 `No ConnectorProvider found for plugin-driven catalog`。 +- 反向断言：非重放路径（`CREATE CATALOG`）对同一个类型必须报错，且文案里能看到已注册类型列表。**这条不能漏** —— 否则「删白名单」会退化成「任何拼错的 type 都静默建出一个坏目录」。 + +**（4）不要破坏的既有测试。** `ExternalCatalogTest.testShowCreateCatalogMasksSensitiveProperties`（`:126-167`）刻意用「重放降级」这条路注册一个 `type=iceberg` 的目录（fe-core 单测里加载不到 iceberg 插件）。改动后它走的是新的第 ③ 步而不是原来的白名单分支，行为必须完全一样：目录注册成功、`SHOW CREATE CATALOG` 能打出被脱敏的属性。跑测试时**必须禁用 maven build cache**，否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的。 + +**（5）编译门禁。** 全反应堆**含测试源**的 `test-compile`（禁用任何跳过测试编译的参数）。这是本任务最强的单一信号：`SPI_READY_TYPES` 是私有字段，只有注释引用它，所以编译不会替你发现漏改的注释 —— 但它会替你发现所有漏改的调用点。maven 用绝对路径的 `-f`。 + +**（6）端到端回归。** 需要跑一轮既有的外部目录建目录用例（hms / iceberg / paimon / jdbc / es 各至少一个 `CREATE CATALOG` + 一次查询），确认这七个类型的建目录行为逐字不变。**必须专门跑一次

+| 新开关塞错位置，把 hudi 的兄弟查找也挡掉 | 这是本任务**唯一的高危错误**：hudi 表会整体读不出来，而且 fe-core 单测未必能发现。对策是 5.1 第（2）条那张表（开关只作用于建独立目录的入口）+ 第（1）（6）条的双向断言与 hudi 端到端用例 | +| 打错字的 `type` 从「明确报错」变成「静默建坏目录」 | 只可能发生在实现漏掉第 ③ 步的非重放分支时。第（3）条的反向断言专门守这个 | +| 第三方插件遮蔽内建类型名（`doris` / `test` / `lakesoul`） | 插件优先的顺序带来的固有代价，换取现有七个类型行为不变。已写进 `getType()` 契约文档；插件之间的撞名由注册冲突检测挡住 | +| 重放语义从抛异常改成降级注册 | 这是本任务有意为之的净改善。已核实全仓（含 `regression-test/`）没有任何测试断言 `Unknown catalog type` 或 `No connector plugin loaded` 这两条文案，没有测试依赖旧行为 | +| Gson 持久化兼容 | **无影响**。第三方目录持久化为 `PluginDrivenExternalCatalog`，`GsonUtils.java:362-363` 早已注册该子类型；本任务不新增、不删除、不重命名任何持久化类型标签 | + +**回退**：改动集中在 6 个文件、彼此无跨阶段耦合，`git revert` 单个提交即可完整回退。`isStandaloneCatalogType()` 是带默认实现的新增方法，回退它不会让任何连接器编译失败（唯一的覆写在 hudi，随同一提交一起回退）。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` + - 第 4.1 节（1)「目录类型白名单——最该删的一处」：本任务的直接来源，包含 `isStandaloneCatalogType` 的原始草案。 + - 附录 A.1 第 1 条与第 7 条：同一问题的两次独立记录（一条按可扩展性归类、一条按路由归类），复核结论均为「部分成立」。 + - 落地批次表里的「5. 删类型白名单」一行，以及排期建议中「这是唯一能真正兑现『新增连接器不需要修改公共模块』的一批；在它合入之前，这个承诺在代码上是假的」。 +- `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorStatementScopes.java:22-51`：类型名唯一性契约的下游消费者，本任务第（4）条冲突检测要保护的正是它的前提。 +- `fe/fe-connector/fe-connector-hudi/src/main/java/org/apache/doris/connector/hudi/HudiConnectorProvider.java:25-39`：hudi 为什么没有独立目录概念，写得比本文更细，改注释前先读它。 +- 相邻但不在本任务范围内的同类问题（都在审计报告里各有条目）：`CreateTableInfo` 里建表能力的四处协同硬编码、`PluginDrivenExternalTable` 里两份重复的 engine 展示名 `switch`、`FileQueryScanNode` 的文件缓存准入类型白名单。它们和本任务是同一个病根的不同发作点，但各自独立可做。 + +--- + +## 九、落地记录（2026-07-25，两个提交） + +**提交**：`[refactor](catalog) remove the catalog type allow-list so a registered connector is reachable`（生产改动 + 测试）、`[doc](catalog) stop pointing at the deleted catalog type allow-list`（纯注释）。 + +### 动手前按符号复核的结论 + +任务文档的核心事实全部成立：8 个 provider（`hms` `iceberg` `paimon` `jdbc` `es` `max_compute` `trino-connector` `hudi`）、白名单 = 8 减 hudi、兄弟查找不经白名单、插件目录批次已按名字判重而类路径批次与跨批次都不判重、全仓（含 `regression-test/`）无任何测试断言 `Unknown catalog type` 或 `No connector plugin loaded` 两条文案。 + +**六处需要修正或补充**： + +1. **文案变化面比文档写的大。** 不只是「引擎不认识的类型」——原白名单内 7 个类型在**插件缺失**时的报错文案也变了（旧文案专门提到 `connector_plugin_root`）。已核实无测试依赖，写进了提交信息。 +2. **删字段留下 20 处悬空注释**（分布 15 个文件），文档只点了必须改的 4 处。已按第二个提交处理。其中 **6 处在本轮之前就已经是错的**（iceberg 那批仍写着「iceberg 还没进白名单、所以代码不可达」，有一处甚至说「没有 iceberg 分片到达 BE」），这些直接删除而不是改写。 +3. **删字段后 `ImmutableSet` / `Set` 两个 import 会孤立**，`test-compile` 不报、`checkstyle` 报。本轮因为保留了 `BUILTIN_CATALOG_TYPES` 仍在用，未触发。 +4. **三段式不需要新增数据结构**：把原 `switch` 的 `default` 分支改写成第三段即可，文档描述得像要再维护一个集合。 +5. **`CREATE CATALOG` 是目录级 CREATE 权限、不是管理员权限**，所以「报错列出已注册类型」确实是对非管理员暴露插件清单。已拍板列出（对齐 Trino 同类报错），并**过滤掉非独立类型**——把一个建不出来的名字列给用户会误导。 +6. **文档把「插件可遮蔽内建类型名」当固有代价接受，实际有更好解法**：Trino 的做法是单一注册表 + 重名直接拒绝。本轮借了后半段——`doris` / `test` / `lakesoul` 成为保留字，在**注册期**拒绝，于是「遮蔽」这个风险不存在，路由顺序也不再影响正确性。 + +### 与文档方案的差异 + +- 新增 `CatalogFactory.BUILTIN_CATALOG_TYPES`（包内可见）+ `isBuiltinCatalogType()`，`ConnectorPluginManager` 用它做保留字判定。这是文档没有的一项。 +- 类型名检查统一到一个包内可见的 `registerDiscovered(provider, failFast)`，两个加载批次都过它（文档建议如此），顺带覆盖了文档未提的「空白类型名」与「跨批次重名」。 +- `registerProvider`（测试插队）不参与检查，注释写清了原因。 + +### 验证结果 + +- 全反应堆**含测试源** `test-compile` + `checkstyle` 通过（两个提交各跑一次）。 +- 52 个单测通过：`ConnectorPluginManagerTest`（13，新增 8）、`CatalogFactoryPluginRoutingTest`（5，新建）、`HudiConnectorProviderTest`（1，新建）、`ExternalCatalogTest`（3，含刻意走重放降级那条）、`DefaultConnectorContextSiblingTest` / `StoragePropsTest`（各 3）、`PluginDrivenExternalTableEngineTest`（16）、`CreateTableInfoEngineCatalogTest`（9）。 +- **做了三次变异验证**（文档原说不需要，但把开关放错入口是本任务唯一高危错误，值得实证）： + 1. 把独立过滤搬到兄弟查找入口（两个入口对调）→ **两个方向同时变红**：兄弟查找返回 null，且非独立类型能建出目录。 + 2. 把 hudi 的声明改成 `true` → `HudiConnectorProviderTest` 变红。 + 3. 删掉保留字检查 → `providerClaimingAnEngineBuiltinCatalogTypeIsRefused` 变红。 +- **未执行**：端到端（需真集群）。7 个类型各一次建目录+查询、以及**一次 hudi 读取**仍待有集群时跑——单测只能证明路由，证不了整条读取链。 + +### 本轮踩到的坑（供后续批次复用） + +- **`-pl <单模块>` 会从本地仓库解析兄弟模块的旧 jar**。给 `fe-connector-spi` 加了方法后，用 `-pl fe-connector/fe-connector-hudi` 跑测试会报「method does not override」——那是旧 jar，不是代码错。跑连接器模块的测试一律走全反应堆 + `-Dtest=` 过滤。 +- **checkstyle 的方法名正则是 `^[a-z][a-z0-9][a-zA-Z0-9_]*$`**：第二个字符也必须小写，`aTypeThatIsCreatable` 这种测试名会红。 +- **`PluginDrivenExternalCatalog.getConnector()` 会触发 `makeSureInitialized()`**，纯单测里用不了（需要真 Env）。判断「目录是插件建出来的还是降级注册的」改用「假 provider 记录自己被问了几次」，而且这样断言的正是「引擎真的问了插件」这个不变量。 +- **`ConnectorMetadata` 的冻结基线没有被牵动**：本轮加的方法在 `ConnectorProvider`（`fe-connector-spi`），不在那份基线的覆盖范围内，无需重新生成。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/16-replace-source-name-branches.md

`FileQueryScanNode` 在主代码里只有三个子类：`PluginDrivenScanNode`、`TVFScanNode`、`RemoteDorisScanNode`。也就是说白名单里的 hms/iceberg/paimon 三种目录今天**全部**由 `PluginDrivenScanNode` 服务，fe-core 里已经没有各数据源自己的文件扫描节点了。 + +### 2.3 切换目录时的默认库硬编码 `"es"` + +`fe/fe-core/src/main/java/org/apache/doris/catalog/Env.java` 的 `changeCatalog`（6495 行起）在恢复「上次待过的库」之后，补了一段： + +```java +// :6509-6512 +if ("es".equalsIgnoreCase( + (String) catalogIf.getProperties().get(CatalogMgr.CATALOG_TYPE_PROP))) { + ctx.setDatabase("default_db"); +} +``` + +而 `"default_db"` 这个名字在连接器侧已经有权威定义：`fe/fe-connector/fe-connector-es/src/main/java/org/apache/doris/connector/es/EsConnectorMetadata.java:43` 的 `public static final String DEFAULT_DB = "default_db"`。同一个事实在引擎和连接器各写了一份。 + +（补充核实：ES 目录今天已经是插件目录——`fe/fe-core/src/main/java/org/apache/doris/persist/gson/GsonUtils.java:366` 把持久化别名 `"EsExternalCatalog"` 映射到 `PluginDrivenExternalCatalog`，fe-core 里已无 `EsExternalCatalog` 类，所以「按类型查 provider」这条路对它是通的。） + +### 2.4 查询剖析里两个源专有常量 + +`fe/fe-core/src/main/java/org/apache/doris/common/profile/SummaryProfile.java` 有两个常量： + +```java +// :158-159 +public static final String ICEBERG_SCAN_METRICS = "Iceberg Scan Metrics"; +public static final String PAIMON_SCAN_METRICS = "Paimon Scan Metrics"; +``` + +它们出现在两张表里：显示顺序表 `EXECUTION_SUMMARY_KEYS`（218～219 行）和缩进表 `EXECUTION_SUMMARY_KEYS_INDENTATION`（278～279 行）。连接器侧各有一份逐字相同的字符串字面量，并在注释里声称必须与 fe-core 常量一致：`fe/fe-connector/fe-connector-iceberg/.../IcebergScanProfileReporter.java:52-53`、`fe/fe-connector/fe-connector-paimon/.../PaimonScanMetrics.java:47-48`。 + +真实机制已核实为：连接器交出的 `ConnectorScanProfile` 由 `PluginDrivenScanNode.writeScanProfilesInto`（420 行起）转写，分组名被用来 **get-or-create 一个子剖析节点**（427～428 行 `new RuntimeProfile(profile.getGroupName())` + `executionSummary.addChild(...)`），子节点的顺序就是插入顺序。而上面那两张表只作用于**信息字符串**：`SummaryProfile.init()`（520 行起）给 `EXECUTION_SUMMARY_KEYS` 里每个键无条件塞一条 `"N/A"`；缩进表只在 `RuntimeProfile.prettyPrint` 打印本节点自己的信息字符串时被查（409～410 行）。 + +## 三、为什么这是个问题 + +**第一处（事件同步预热）——文档承诺与代码不符，且有真实后果。** 调研报告把后果写成「事件源永远不会被激活」，实测要收窄：已初始化的目录走的是完全中立的能力探针，一旦目录被查询过一次就正常同步。准确的后果是：**在某个 FE 上从未被初始化过的目录，其事件游标不会被自动播种**。这在多 FE 部署里是真实的——每个 FE 各自跑一份驱动、各自维护游标，而 follower 上通常没人发查询，于是一个实现了 `getEventSource()` 的新连接器在 follower 上（以及 FE 重启后到首次查询之间）拿不到增量同步，只能等有人查它。这正是 108～118 行注释为 HMS 特意保留强制预热的原因，新连接器却拿不到同一份照顾。同时 `getEventSource()` 文档里那句「从不用 `instanceof`」在这条分支上是假的——按类型名筛选和 `instanceof` 是同一件事的两种写法。 + +**第二处（文件缓存准入）——目前不是 bug，是扩展点。** 今天的覆盖是正确的：白名单外的 jdbc / trino / max_compute 走 JNI 读取，本来就没有 BE 文件缓存，跳过路径还有 `LOG.debug` 兜底。问题在判据错位：治理的真实前提是「这个连接器的数据由 BE 原生文件读取器读取，因此 BE 文件缓存对它有效」，代码却写成「目录类型叫这三个名字之一」。将来新增一个 BE 原生读文件的湖格式连接器，它的表会静默绕过缓存准入治理（用户设置了库/表级的缓存准入规则，对这个新目录不生效，且没有任何报错），必须改 fe-core 才能纳入。 + +**第三处（默认库）——SPI 缺一个声明位。** 「切到本目录时自动进入某个默认库」是数据源自己的事实（ES 没有库的概念，Doris 给它造了一个 `default_db`），却只能由引擎硬编码。新连接器要这个行为必须改 `Env`。 + +**第四处（剖析常量）——中立性瑕疵 + 每个查询两行垃圾。** `ICEBERG_SCAN_METRICS` / `PAIMON_SCAN_METRICS` 已核实**没有任何地方给它们赋值**（全仓 grep：只有常量声明、两张表、以及镜像断言的测试）。于是每个查询的执行摘要里都无条件多出两行 `- Iceberg Scan Metrics: N/A` 和 `- Paimon Scan Metrics: N/A`；而真正的 iceberg/paimon 扫描指标是以**同名子节点**的形式挂上去的，于是同一份剖析里会出现「一行 N/A 的条目」和「一个同名的子树」并存，反而更容易看错。缩进表里那两条对子节点完全无效（子节点的信息字符串键是各自的指标名，不在缩进表里）。连接器注释里「MUST equal fe-core 常量（display ordering）」的说法与实际机制不符：分组名是连接器自选的子节点名字，fe-core 不需要预先知道它。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 `X`（一个 BE 原生读 Parquet 的新湖格式，带元数据变更事件源，并且它的元数据模型没有「库」这一层，希望切进去就落到一个固定库）。我今天必须动的公共模块文件： + +| 我想要的行为 | 今天实际发生什么 | 我今天必须改哪里 | 改完本任务后 | +|---|---|---|---| +| 目录的元数据变更能自动同步 | 我实现了 `getEventSource()`，master 上查过一次的目录能同步；follower 上（没人查）游标从不播种，一直不同步 | `MetastoreEventSyncDriver.java:119`，把 `"x"` 加进类型判断 | 在 `XConnectorProvider` 里 `providesEventSource()` 返回 `true` | +| 我的表纳入 BE 文件缓存准入治理 | 用户配的缓存准入规则对我的目录静默不生效，只有一行 `LOG.debug` | `FileQueryScanNode.java:119`，把 `"x"` 加进 `CACHEABLE_CATALOGS` | 在 `XScanPlanProvider` 里 `supportsFileCache()` 返回 `true` | +| `SWITCH x;` 之后自动进入 `default_db` | 停在没有库的状态，用户必须显式 `USE` | `Env.java:6509`，在 `"es"` 旁边加 `"x"` | 在 `XConnectorProvider` 里 `defaultDatabaseOnUse()` 返回库名 | +| 在查询剖析里输出我的扫描指标 | 实际上**已经可以**（分组名自选，无需 fe-core 登记）；但 fe-core 的注释与常量表让人以为必须先去加常量 | 误以为要改 `SummaryProfile.java:158` | 什么都不用改（那两个常量已删） | + +用户视角的一个具体现象（第四处）：今天任意一条查询 + +```sql +SET enable_profile = true; +SELECT count(*) FROM internal.some_db.some_olap_table; +``` + +的执行摘要里也会出现 + +``` +- Iceberg Scan Metrics: N/A +- Paimon Scan Metrics: N/A +``` + +——这条查询跟 iceberg / paimon 毫无关系。删掉这两个常量是修正，不是回归。 + +## 五、解决方案 + +### 5.1 目标状态 + +**`ConnectorProvider` 新增两个默认方法**（`fe/fe-connector/fe-connector-spi/src/main/java/org/apache/doris/connector/spi/ConnectorProvider.java`）。挂在 provider 而不是 `Connector` 上是这条任务的关键判断：这两处判定发生在目录**可能尚未初始化**的时刻（事件驱动的预热分支、`SWITCH` 时可能还没碰过连接器），只能按类型查 provider；碰 `Connector` 实例会强制初始化，引入现状没有的副作用（正好是 `MetastoreEventSyncDriver` 108～118 行注释要避免的事）。 + +```java +/** + * 本类型的连接器是否会通过 Connector#getEventSource() 暴露增量元数据变更源。 + *

`supportsTableSample`（268 行）放，照抄它们的 opt-in 形状）： + +```java +/** + * 本连接器规划出的扫描范围是否由 BE 的原生文件读取器读取（因此 BE 文件缓存对它有效， + * 引擎应对它的表施加文件缓存准入治理）。JNI 读取的连接器必须保持 false —— + * 它们不经过 BE 文件缓存，做准入判定只是白花一次远程/本地开销。默认

查表入口**：`ConnectorFactory`（`fe/fe-core/src/main/java/org/apache/doris/connector/ConnectorFactory.java`）加静态 `findProvider(String catalogType, Map properties)` 返回 `Optional`，委派给 `ConnectorPluginManager` 里一个新的同名方法——该方法复用 `createConnector`（127 行起）里现成的选择逻辑（第一个 `supports(...)` 为真且 `apiVersion` 匹配的 provider），只是不 `create`。plugin manager 未初始化时返回空。 + +关于「fe-core 只出不进」：这个查表入口是**中立**的（不含任何数据源名），它的存在是为了删掉三处数据源名判定；本任务在 fe-core 里的数据源相关代码是净减的。这不属于「为了让删除能编译过就把逻辑挪进 fe-core」。 + +**三处判定改写后的样子**： + +- `MetastoreEventSyncDriver.java:119` → `if (!providesEventSource(pluginCatalog.getType(), pluginCatalog.getProperties())) { continue; }`，其余（`makeSureInitialized()` 的 try/catch、`!isInitialized()` 的一次性守卫）一字不动。 +- `FileQueryScanNode.java:757` →

行），非 null 则返回 `supportsFileCache()`」。删掉 `CACHEABLE_CATALOGS` 常量与随之失效的 `java.util.Arrays` import（81 行；`HashSet` 在 455 行仍有用，别删）。 +- `Env.java:6509-6512` → 查 provider 的 `defaultDatabaseOnUse()`，非空则 `ctx.setDatabase(...)`。**保持原有位置与覆盖语义**：仍在「恢复上次待过的库」之后执行，即声明了默认库的目录会覆盖 `lastDb`。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +| `fe/fe-connector/fe-connector-spi/.../ConnectorProvider.java` | 新增

`CACHEABLE_CATALOGS`（117～121 行）与 `Arrays` import（81 行）；757 行改为调用新的 `protected boolean isFileCacheAdmissionApplicable()`（默认 false，带注释说明默认 false 保持 TVF / 远程 Doris 扫描节点的现状） | +|

`fe/fe-core/.../common/profile/SummaryProfile.java` | 删 `ICEBERG_SCAN_METRICS` / `PAIMON_SCAN_METRICS`（158～159 行）及其在 `EXECUTION_SUMMARY_KEYS`（218～219 行）、`EXECUTION_SUMMARY_KEYS_INDENTATION`（278～279 行）里的条目 | +| `fe/fe-connector/fe-connector-hive/.../HiveConnectorProvider.java` | `providesEventSource()` 返回 `true`（`getType()` 已核实为 `"hms"`，37～39 行） | +|

不动的连接器**（今天不在白名单里，改后必须仍然不做准入判定）：`MaxComputeScanPlanProvider`、`TrinoScanPlanProvider`、`JdbcScanPlanProvider`、`EsScanPlanProvider`。不要「顺手都开上」。 + +### 5.3 明确不要顺手做的事 + +- **不要给 `Connector` 也加一份 `providesEventSource()`。** 同一能力两个高度会立刻产生「哪个是真的」的问题；`Connector.getEventSource()` 仍是唯一事实来源，provider 上那个只是「未初始化时的先行声明」，靠 javadoc 约束一致，并由 5.1 说明的原因决定它必须在 provider 上。 +- **不要顺手改事件驱动的其它行为**：`!isInitialized()` 的一次性守卫、`makeSureInitialized()` 的吞异常重试、self-heal 的游标重置（149 行）都是刻意对齐迁移前行为的，本任务只换判据。 +- **不要把 `defaultDatabaseOnUse()` 扩成「默认目录/默认会话属性」框架**，也不要顺手改 `changeDb`。只做一个可选库名。 +- **不要顺手删 `SummaryProfile` 里其它看起来源专有的常量**（`HMS_ADD_PARTITION_TIME`、`GET_PARTITIONS_TIME` 等）：那些有真实赋值点（`GET_PARTITIONS_TIME` 在 635 行、`HMS_ADD_PARTITION_TIME` 在 713～714 行，等等），删了就是功能回归。本任务只删已核实无赋值点的那两个。 +- **不要把 `CACHEABLE_CATALOGS` 的语义换成「是否 JNI 格式」之类的现场推断**（例如照 `fileFormatType == FORMAT_JNI` 判断）：扫描级的格式判定另有一套坑，且那仍是引擎在猜连接器的事实。就用连接器声明。 +- **不要为这三处写 shell / 正则构建门禁**（例如「grep 不允许出现 `"hms".equalsIgnoreCase`」）：本仓库已有结论，这类门禁只适合存在性与前缀类不变量，判断语言语义的门禁误报比漏报更毒。用单测 + 评审。 +- **不要顺手动 `CatalogFactory.SPI_READY_TYPES`**（`fe/fe-core/.../CatalogFactory.java:56-57`）。那也是一张类型名白名单，但它是另一件事（决定一个类型能不能建目录），风险与验证面完全不同，属于另一条任务。 + +## 六、怎么验证 + +**编译门禁（最强单一信号）**：全反应堆**含测试源**的编译 + +```bash +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T 1C test-compile +``` + +不要加任何跳过测试编译的参数。理由：新增的是 SPI 默认方法 + 各连接器覆写，编不过的地方（比如某个连接器模块看不到 `Optional` import、或测试仍引用被删的常量）只有把测试源一起编译才会暴露。 + +**单元测试**（跑测试时必须禁用 maven build cache，否则 surefire 会被静默跳过而 `BUILD SUCCESS` 是空的）： + +1. `MetastoreEventSyncDriver` 的预热筛选：现在没有任何直测这个类行为的测试（已核实唯一提到它的是 `fe/fe-core/src/test/java/org/apache/doris/datasource/ExternalMetaIdMgrTest.java`，那里只把它当协作者 `Mockito.mock` 掉、不验证它自己的筛选逻辑），需要新建一个。断言的是**意图**而不是形状：注册两个假 provider（一个声明有事件源、一个不声明）+ 两个未初始化的假插件目录，跑一次 `runAfterCatalogReady()`，断言只有前者的目录被 `makeSureInitialized()` 触碰过（用计数器记录），后者**一次都没有被触碰**（这条就是「空闲目录不得被强制初始化」的守卫，去掉声明位判定后这条会失败——即它能在业务逻辑变化时失败）。 +2. 文件缓存准入的适用性：给 `PluginDrivenScanNode` 加用例，`supportsFileCache()` 为 `true` / `false` / provider 为 `null` 三种情形下 `isFileCacheAdmissionApplicable()` 的返回值；再补一条断言 `FileQueryScanNode` 的默认实现为 `false`（现有 `FileQueryScanNodeTest` 里已有可复用的 `TestFileQueryScanNode`，63 行）。 +3. `changeCatalog` 的默认库：假 provider 声明 `defaultDatabaseOnUse()` 返回某个库名，断言切换后 `ctx.getDatabase()` 落到该库、且**覆盖了**先前记住的 `lastDb`（这条钉住的是现状语义，不是新语义）；再断言未声明的目录不改动 `lastDb` 恢复结果。 +4. 剖析常量删除：`PluginDrivenScanNodeScanProfileTest` 剩余用例（分组 get-or-create、两个扫描子节点各自的指标）必须继续通过——它们证明扫描剖析的分组不依赖被删的常量。连接器侧 `IcebergScanProfileReporterTest`（104 行）、`PaimonScanMetricsTest`（80 行）对自身 `GROUP_NAME` 字面量的断言保留不动。 + +**变异验证**（推荐做，成本很低）：把新加的三个默认方法的默认值分别从 `false`/空翻成 `true`/非空，确认至少有一条测试变红；再把某个连接器的覆写删掉，确认对应测试变红。若翻转后全绿，说明测试没有真的在验证行为。 + +**端到端回归**：本地无集群时不跑，需要集群的择机补。要点是三条： + +- 一个 hms 目录在 FE 重启后不查询、直接等事件同步（验证预热路径仍然生效，行为与改动前一致）； +- hms 目录下的 hive / iceberg / hudi 表 + 独立 iceberg / paimon 目录，在打开 `enable_file_cache_admission_control` 并配了库级准入规则时，规则仍然生效（验证白名单→能力位迁移零行为差）； +- `SWITCH ;` 之后 `SELECT DATABASE()` 仍是 `default_db`。 + +**人工核对**：打开一条普通内表查询的剖析，确认 `Iceberg Scan Metrics: N/A` / `Paimon Scan Metrics: N/A` 两行消失，而 iceberg / paimon 查询的扫描指标子树照旧出现。 + +## 七、风险与回退 + +| 风险 | 说明与缓解 | +|---|---| +| 文件缓存准入治理漏声明 → 静默丢治理 | 最需要小心的一处，尤其是 hudi（今天靠 hms 白名单覆盖，改后要靠 hudi 兄弟的 provider 声明）。缓解：改动清单里逐个连接器列明 true/false；单测覆盖三态；上线前用 hms 异构目录（hive + iceberg + hudi 同库）跑一次准入规则生效断言 | +| provider 声明与 `Connector.getEventSource()` 不一致 | 若 provider 声明了 `true` 但连接器实际不返回事件源，后果只是白做一次强制初始化（132 行仍会判 `null` 跳过），不影响正确性；反向（声明 false 但有事件源）等于保持今天的缺陷。靠 javadoc 明确「两者必须一致」+ 连接器侧单测断言 | +| 从 fe-core 调用插件代码的类加载器 | 三个新方法都是返回常量的纯 getter（没有远程调用、没有按名反射），与已在用的 `provider.getType()` / `supports()` 同性质，不需要固定线程上下文类加载器。评审时确认没有人在实现里做重活 | +| 删剖析常量导致外部工具解析失败 | 已核实这两行恒为 `N/A`、无赋值点，且 `regression-test/` 与 `docs/` 里零引用（grep `"Scan Metrics"` 无命中）。若某个外部脚本硬解析执行摘要行数，会受影响——这属于删掉一条恒为空的行的正常代价 | +| `changeCatalog` 每次切目录多一次 provider 遍历 | provider 列表是个位数的 `CopyOnWriteArrayList`，`supports()` 契约要求廉价且无网络调用；切目录不是热点路径 | + +**回退**：四处彼此独立，建议拆成 4 个提交（事件同步预热 / 文件缓存能力位 / 默认库 / 剖析常量），任一处出问题单独回退即可。SPI 上新增的都是**默认方法**，回退 fe-core 侧调用点后接口留着也不影响任何连接器编译。本任务不涉及 Gson 持久化格式与 thrift 有线格式，无兼容性尾巴。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`： + - 第 4.2 节「软阻塞：连接器能跑，但拿不到与既有数据源同等的行为」——按类型名字符串判定的四处清单（含表格），以及第四处剖析常量的提及。表格里第四行（配置项逐键手工转发）**不属于**本任务，见报告 4.5 节。 + - 附录 A 第 5 条（事件驱动里硬编码 `"hms"`）与第 30 条的复核收窄（`getEventSource` 的中立承诺在未初始化目录上是假的）——两处合起来给出事件同步预热的准确影响面：「本 FE 上从未初始化过的目录不会被强制预热」，不是「永远不会被激活」。 + - 附录 A 第 13 条——剖析分组名必须匹配 fe-core 的源专有常量表，结论是那两个常量应删。 + - 附录 A 第 15 条——文件缓存目录类型白名单当前不是 bug、只是扩展点。 + - 第 4.3 节「不阻塞但仍是按类型分支的地方」——`PluginDrivenExternalTable.getEngine()` 那两张同样按类型名的展示名表，报告结论是**不下沉**、只合并去重，不要顺手卷进本任务。 +- 已有的能力位 opt-in 先例：`ConnectorScanPlanProvider.supportsBatchScan`（250 行）、`supportsTableSample`（268 行）、`scannedPartitionCount`（291 行）——新加的 `supportsFileCache()` 照抄它们的形状与文档风格。 +- 同任务集：编号 07《把设计规则写下来》——本任务确立的「按类型查 provider 用于未初始化时刻的判定，碰连接器实例会引入强制初始化副作用」这条经验，值得写进规则文档。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/17-typed-per-table-capabilities.md

`PluginDrivenExternalTable.hasScanCapability`（`fe/fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenExternalTable.java:302`）： + +```java +if (connector.getCapabilities().contains(capability)) { + return true; +} +String csv = rawTableProperties().get(ConnectorTableSchema.PER_TABLE_CAPABILITIES_KEY); +... +for (String name : csv.split(",")) { + if (name.trim().equals(capability.name())) { return true; } +} +return false; +``` + +它的调用方只有 5 处，对应 5 个能力：`supportsColumnAutoAnalyze`（`:239`）、`supportsTopNLazyMaterialize`（`:251`）、`supportsNestedColumnPrune`（`:264`）、`supportsNestedColumnSchemaChange`（`:276`）、`supportsSampleAnalyze`（`:289`）。 + +字符串从连接器传到引擎的载体是进程内的 schema 缓存值 `PluginDrivenSchemaCacheValue.tableProperties`（`fe/fe-core/src/main/java/org/apache/doris/datasource/plugin/PluginDrivenSchemaCacheValue.java:57`），由 `PluginDrivenExternalTable.toSchemaCacheValue`（`:491`，末尾把整个 `tableSchema.getProperties()` 原样交给缓存值）填入，读取入口是私有的 `rawTableProperties()`（`:752`）。已核实 `SchemaCacheValue` 及其子类**没有任何 Gson 注解、不参与元数据持久化**，所以改字段没有镜像兼容负担。 + +### 2.3 其余 8 个能力：只读连接器级集合，完全绕过字符串通道 + +除 `hasScanCapability` 之外，引擎侧还有 **9 处**直接 `connector.getCapabilities().contains(...)`： + +| 位置 | 读的能力 | 作用域 | +|---|---|---| +| `PluginDrivenExternalTable.java:337` | `SUPPORTS_SHOW_CREATE_DDL` | 表 | +| `PluginDrivenExternalTable.java:353` | `SUPPORTS_VIEW` | 表 | +| `PluginDrivenExternalTable.java:438` | `SUPPORTS_METADATA_PRELOAD` | 表 | +| `ShowPartitionsCommand.java:350`（私有方法 `hasPartitionStatsCapability`，被 `:293` 与 `:390` 两处调用） | `SUPPORTS_PARTITION_STATS` | 表（但 `:390` 的 `getMetaData()` 路径上没有解析出表对象） | +| `PluginDrivenExternalCatalog.java:316` | `SUPPORTS_VIEW` | 目录（在列表名字，此时没有表） | +| `PluginDrivenExternalCatalog.java:1289` | `SUPPORTS_USER_SESSION` | 目录 | +| `PluginDrivenExternalDatabase.java:60` | `SUPPORTS_MVCC_SNAPSHOT` | 库（决定新建哪个表子类，此时表还没建出来） | +| `QueryTableValueFunction.java:78` | `SUPPORTS_PASSTHROUGH_QUERY` | 目录（表值函数，没有表） | +| `CreateTableInfo.java:794` | `SUPPORTS_SORT_ORDER` | 目录（建表语句分析期，表还不存在） | + +上表是 `fe-core` 侧的全部。连接器内部另有一处同形状的读取：`HiveConnector.java:543` 读兄弟连接器的 `SUPPORTS_USER_SESSION` 做越权守卫。它不属于引擎侧统一入口的范围，本任务不动它。 + +### 2.4 写路径的 7 项特性在两个接口上各有一份 + +真源是 `ConnectorWritePlanProvider`（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/write/ConnectorWritePlanProvider.java`）上的 7 个默认方法：`supportedOperations()`（`:159`）、`supportsWriteBranch()`（`:164`）、`requiresParallelWrite()`（`:174`）、`requiresFullSchemaWriteOrder()`（`:184`）、`requiresPartitionLocalSort()`（`:194`）、`requiresPartitionHashWrite()`（`:210`）、`requiresMaterializeStaticPartitionValues()`（`:220`）。三个连接器覆写它们（`IcebergWritePlanProvider:321-345`、`HiveWritePlanProvider:124-141`、`MaxComputeWritePlanProvider:145-162`）。 + +而 `Connector` 上又镜像了 **11 个**同名方法：`supportedWriteOperations()`（`:115`）、`supportedWriteOperations(handle)`（`:126`）、`supportsWriteBranch()`（`:132`）、`supportsWriteBranch(handle)`（`:138`）、`requiresParallelWrite()`（`:144`）、`requiresFullSchemaWriteOrder()`（`:150`）、`requiresPartitionLocalSort()`（`:156`）、`requiresPartitionHashWrite()`（`:162`）、`requiresPartitionHashWrite(handle)`（`:168`）、`requiresMaterializeStaticPartitionValues()`（`:177`）、`requiresMaterializeStaticPartitionValues(handle)`（`:183`）。方法体一律是同一个形状： + +```java +default boolean requiresParallelWrite() { + ConnectorWritePlanProvider p = getWritePlanProvider(); + return p != null && p.requiresParallelWrite(); +} +``` + +已实测：**没有任何连接器覆写这 11 个方法中的任何一个**（`fe-core` 的 `ConnectorWriteDelegationTest:67` 那处覆写是覆写在 provider 上的，不是覆写在 `Connector` 上）。调用方全部在引擎侧与契约校验器里：`PluginDrivenExternalTable:178/206/223/367/388/403/423`、`PhysicalPlanTranslator:630/682`、`ConnectorContractValidator:42-70`。 + +7 项特性里只有 4 项有「按表」重载（`supportedWriteOperations` / `supportsWriteBranch` / `requiresPartitionHashWrite` / `requiresMaterializeStaticPartitionValues`），另外 3 项（`requiresParallelWrite` / `requiresFullSchemaWriteOrder` / `requiresPartitionLocalSort`）没有——这是历史上按需一个个加出来的，不是设计。 + +--- + +## 三、为什么这是个问题 + +**（1）字符串通道没有编译期约束，写错就静默失效。** 能力名写成 `"SUPPORTS_TOPN_LAZY_MATERIALIZ"`（少一个字母），编译通过、启动通过、`SHOW CREATE TABLE` 也看不出来，只是这张表永远拿不到 Top-N 延迟物化——退化成一次性能损失，没有任何报错。 + +**（2）接口文档承诺的范围和实现范围不一致。** `ConnectorTableSchema.java:82-97` 的注释写的是「本表支持的能力名」，语气上任何能力都可以按表细化；实际只有 5 个能力的读取路径会看这个串（第 2.2 节的 5 个调用方），另外 8 个只读连接器级集合。**而且哪 5 个生效这件事没有写在任何地方**，只能靠反查引擎里那个私有方法的调用方才能知道。 + +**（3）hive 网关往里塞的东西大部分被静默丢弃。** `reflectSiblingScanCapabilities` 把 iceberg 兄弟的整个能力集合都拼进串里。iceberg 的集合里含 `SUPPORTS_SHOW_CREATE_DDL` / `SUPPORTS_VIEW` / `SUPPORTS_METADATA_PRELOAD` / `SUPPORTS_SORT_ORDER` / `SUPPORTS_MVCC_SNAPSHOT`（`IcebergConnector.java:849-857`），这些在引擎侧一个都不会被读到。「多发的会被丢掉」这件事现在是**引擎读取范围窄**这个实现细节在兜着，而不是连接器明确表达了意图——它同时也是下面这个改动的陷阱：一旦引擎把读取范围扩大，这些被丢弃的能力会**突然生效**，iceberg-on-HMS 表的 `SHOW CREATE TABLE`、视图判定、元数据预载行为会在没人评审过的情况下改变。 + +**（4）名字是错的。** `hasScanCapability` 里的 "scan" 早就不成立：它服务的 5 个调用方里有 `ALTER TABLE` 嵌套列演进（`supportsNestedColumnSchemaChange`）和统计信息采集（`supportsColumnAutoAnalyze` / `supportsSampleAnalyze`），跟扫描无关。 + +**（5）写特性的镜像方法给同一个事实开了第二个可覆写入口。** 今天 0 个连接器覆写它们，所以没出事——但那是运气，不是设计保证。假设某个连接器作者在 `Connector` 上覆写 `requiresParallelWrite()` 返回 `true`，而没有同步改自己的写计划提供者：`PhysicalConnectorTableSink` 走 `Connector` 这条路会拿到 `true`，任何直接问 provider 的地方拿到 `false`，两个答案分叉。**这种分叉没有任何测试能捕获**，因为两条路各自都「符合自己的契约」。这也直接违背 07 号要写下的第二层规则：子系统内部的开关只挂在拥有它的那个 provider 上，禁止在入口接口上做镜像转发。 + +--- + +## 四、用一个最小例子说明 + +**例子一：连接器写了什么 vs 引擎实际怎么理解。** + +| 连接器写下的东西 | 今天实际发生什么 | 应该发生什么 | +|---|---|---| +| `props.put(键, "SUPPORTS_SAMPLE_ANALYZE")` | 生效 | 生效（类型化后写成 `EnumSet.of(SUPPORTS_SAMPLE_ANALYZE)`） | +| `props.put(键, "SUPPORTS_SAMPLE_ANALYZ")`（拼错） | **静默失效**：这张表永远不能 `ANALYZE ... WITH SAMPLE`，无任何日志 | **编译不过**（枚举常量不存在） | +| hive 把 iceberg 兄弟的 `SUPPORTS_SHOW_CREATE_DDL` 也拼进串里 | 引擎不读这一项，**静默丢弃**；iceberg-on-HMS 表的 `SHOW CREATE TABLE` 不走连接器渲染 | hive 只反射它确实想让表继承的那几项，不发多余的；行为不变但意图写在代码里 | + +**例子二：镜像方法怎么分叉。** 假设新连接器作者这样写（完全合法、编译通过、评审也很难看出）： + +```java +class MyConnector implements Connector { + // 作者以为这是"声明我的写能力"的地方 + @Override public boolean requiresParallelWrite() { return true; } + @Override public ConnectorWritePlanProvider getWritePlanProvider() { return new MyWriteProvider(); } +} +class MyWriteProvider implements ConnectorWritePlanProvider { + // 而这里没写，默认 false +} +``` + +于是：`connector.requiresParallelWrite()` 得到 `true`，`connector.getWritePlanProvider().requiresParallelWrite()` 得到 `false`。改成静态派生函数之后，上面那个 `@Override` **根本写不出来**——`Connector` 上没有这个方法可覆写，唯一的真源由语言保证。 + +--- + +## 五、解决方案 + +### 5.1 目标状态 + +**（一）按表能力改成类型化集合。** `ConnectorTableSchema` 新增一个能力字段，字符串键删除： + +```java +// fe-connector-api：ConnectorTableSchema +private final Set tableCapabilities; + +/** 不做按表细化的连接器沿用这个构造器（能力集合为空）。 */ +public ConnectorTableSchema(String tableName, List columns, + String tableFormatType, Map properties); + +/** 需要按表细化的连接器（今天只有 hive）用这个。 */ +public ConnectorTableSchema(String tableName, List columns, + String tableFormatType, Map properties, + Set tableCapabilities); + +/** 本表在连接器级集合之外额外支持的能力；默认空集，绝不为 null。 */ +public Set getTableCapabilities(); +``` + +调研报告建议加建造器，这里**故意不加**：只多一个字段，两个构造器就够了；加建造器会与现有 23 个 `new ConnectorTableSchema(...)` 构造点长期并存，正好制造出这轮清理要消除的那种「同一件事两条通道」。 + +`PER_TABLE_CAPABILITIES_KEY` 连同它在 `RESERVED_CONTROL_KEYS` 里的登记一起删掉。 + +**（二）能力集合沿 schema 缓存往下走。** `PluginDrivenSchemaCacheValue` 增一个 `Set tableCapabilities` 字段（与已有的 `tableProperties` 并列，同样只活在进程内缓存里），`toSchemaCacheValue` 从 `tableSchema.getTableCapabilities()` 取。 + +**（三）引擎侧表作用域能力统一走一个入口。** `hasScanCapability` 改名 `hasCapability`（仍是私有），语义仍是「连接器级 ∪ 本表级」，只是本表级从解析字符串变成读集合；`PluginDrivenExternalTable` 里 3 处直读（`:337` / `:353` / `:438`）改走它。 + +**（四）目录作用域能力也统一走一个入口。** 在 `PluginDrivenExternalCatalog` 上加一个通用访问器，替掉 4 个类里重复的 `catalog instanceof ... && getConnector() != null && getConnector().getCapabilities().contains(...)` 样板： + +```java +// PluginDrivenExternalCatalog +public boolean hasConnectorCapability(ConnectorCapability capability); +``` + +这条不违反「fe-core 只出不进」：它不是数据源相关代码，是把已存在的重复判断收成一个通用访问器，整体是净删行。 + +**（五）在枚举上逐条写清作用域。** `ConnectorCapability` 每个常量的注释里补一句它是**按目录解析**还是**按目录 ∪ 按表解析**。核实后的分布是： + +- 按目录 ∪ 按表（8 个）：`SUPPORTS_COLUMN_AUTO_ANALYZE`、`SUPPORTS_SAMPLE_ANALYZE`、`SUPPORTS_TOPN_LAZY_MATERIALIZE`、`SUPPORTS_NESTED_COLUMN_PRUNE`、`SUPPORTS_NESTED_COLUMN_SCHEMA_CHANGE`、`SUPPORTS_SHOW_CREATE_DDL`、`SUPPORTS_VIEW`、`SUPPORTS_METADATA_PRELOAD`。 +- 只能按目录（5 个）：`SUPPORTS_MVCC_SNAPSHOT`（在表对象**建出来之前**就要用它选表子类，读表级集合会形成循环依赖）、`SUPPORTS_USER_SESSION`（目录级凭证投射）、`SUPPORTS_PASSTHROUGH_QUERY`（表值函数，没有表）、`SUPPORTS_SORT_ORDER`（建表语句分析期，表还不存在）、`SUPPORTS_PARTITION_STATS`（两个调用点必须给出一致答案，其中 `getMetaData()` 那条路径上没有表对象，见 5.3）。 + +也就是说，**「5/13」会变成「8/13，剩下 5 个天生只能按目录，并逐条写明原因」**，而不是调研报告里那句 13/13——13/13 在结构上做不到。 + +**（六）hive 收窄反射范围。** `reflectSiblingScanCapabilities` 不再反射兄弟的整个集合，改为反射一个显式列出的「打算让表继承的能力」子集：`SUPPORTS_COLUMN_AUTO_ANALYZE`、`SUPPORTS_SAMPLE_ANALYZE`、`SUPPORTS_TOPN_LAZY_MATERIALIZE`、`SUPPORTS_NESTED_COLUMN_PRUNE`、`SUPPORTS_NESTED_COLUMN_SCHEMA_CHANGE` —— 也就是今天引擎实际会读的那 5 项。取这 5 项而不是「iceberg 兄弟现在恰好声明的那 4 项」，是为了让行为不变这件事**与兄弟连接器声明了什么无关**（iceberg 今天不声明 `SUPPORTS_SAMPLE_ANALYZE`，反射它是空操作；将来若声明，行为与今天一致）。这一步**行为完全不变**（今天多发的部分本来就被丢弃），但它是第（三）步安全的前提：只有先收窄，扩大引擎读取范围才不会顺带改变 iceberg-on-HMS 表的行为。方法名里的 "Scan" 一并去掉。 + +**（七）写特性改成静态派生函数。** `fe-connector-api` 的 write 包下新增： + +```java +public final class ConnectorWriteTraits { + private ConnectorWriteTraits() {} + + /** 连接器级写计划提供者，连接器为 null 时返回 null。 */ + public static ConnectorWritePlanProvider providerOf(Connector connector); + /** 按表的写计划提供者（异构网关据 handle 选子提供者），连接器为 null 时返回 null。 */ + public static ConnectorWritePlanProvider providerOf(Connector connector, ConnectorTableHandle handle); + + // 以下 7 个是空安全解包：provider 为 null 时布尔返 false、集合返空集 + public static Set supportedOperations(ConnectorWritePlanProvider provider); + public static boolean supportsWriteBranch(ConnectorWritePlanProvider provider); + public static boolean requiresParallelWrite(ConnectorWritePlanProvider provider); + public static boolean requiresFullSchemaWriteOrder(ConnectorWritePlanProvider provider); + public static boolean requiresPartitionLocalSort(ConnectorWritePlanProvider provider); + public static boolean requiresPartitionHashWrite(ConnectorWritePlanProvider provider); + public static boolean requiresMaterializeStaticPartitionValues(ConnectorWritePlanProvider provider);

BUCKETS 16` 的建表——**注意这两处都是期望抛异常的否定用例，不是成功建表**：`:437` 那条写了 `ENGINE=olap`，期望 `Cannot create olap table out of internal catalog...`（`:442`）；`:460` 那条期望 `Create hive bucket table need set enable_create_hive_bucket_table to true`（`:465`），拒绝发生在 `analyzeEngine` 之后的 hive 建表阶段，所以它只能**间接**证明 `analyzeEngine` 放行了分桶子句。 + + **分桶子句今天没有正向端到端护栏，本任务必须自己补一条。** 已实测：全仓 `regression-test` 里 `enable_create_hive_bucket_table` 只有上面那一处否定断言，插件目录上「带分桶子句成功建表」的用例一个都不存在（其余 `DISTRIBUTED BY` 命中全部是内部目录的 olap 表）。所以搬迁 `analyzeEngine` 的分桶允许列表时，**不能指望现成用例兜底**：必须新增一条 hive 目录上打开 `enable_create_hive_bucket_table` 后带 `DISTRIBUTED BY HASH(...) BUCKETS N` 成功建表并能写入读回的用例。它是本任务唯一能证明「分桶位声明真的放行了这条子句」的端到端证据；本地无集群时不能因此跳过——跑不了就必须在提交说明里写明该用例已写好但未跑，不要当它通过。作为兜底，第一步单测里那条「声明分桶位的目标放过」的用例必须同批加上（见上表最后一行）。 +- `regression-test/suites/external_table_p0/hive/ddl/test_hive_ctas.groovy` —— CTAS 入口的补引擎名路径。 +- `regression-test/suites/external_table_p0/iceberg/write/test_iceberg_write_partitions.groovy:35` 起 —— iceberg 分区建表。 +- paimon 侧带建表的用例（`regression-test/suites/external_table_p0/paimon/` 下 `test_paimon_table.groovy`、`test_paimon_schema_metadata_atomicity_matrix.groovy` 等）。 +- `regression-test/suites/external_table_p2/maxcompute/test_max_compute_create_table.groovy` —— maxcompute 是唯一同时声明两个能力位的连接器；这套用例在第二档环境，跑不了就必须在提交说明里写明未跑，不要默认它通过。 + +**第三步：显式列出并逐条确认「本来就会失败、只是文案变了」的边角组合。** 把判据从引擎名换成目标目录之后，下面这些组合的报错文案会变（它们改前改后都是拒绝，只是拒绝的位置提前了），动手前要逐条实测确认没有用例依赖旧文案： + +- 内部目录里写 `ENGINE=hive` 且带 `PARTITION BY`：原本先过 `analyzeEngine`、由 `InternalCatalog` 抛「不能在内部目录建 hive 表」，改后在 `analyzeEngine` 就抛分区文案。 +- jdbc 目录里写 `ENGINE=hive` 且带 `PARTITION BY`：原本按引擎名放过分区、到连接器才失败，改后在 `analyzeEngine` 抛分区文案。 +- 已下线的 `doris` / `test` 类型外部目录（`CatalogFactory.java:141-153`，非插件目录）：不带 `ENGINE` 时仍应抛 `Current catalog does not support create table`。 + +若某条组合被现成用例断言了旧文案，就地把该条改成「保留原判据」而不是硬改文案——本任务的目标是搬迁判据，不是改用户可见行为。 + +**第四步：编译门禁。** 全反应堆**含测试源**的 `test-compile` 通过（绝对路径 `-f`，禁用任何跳过测试编译的参数），这是最强的单一符号级信号。跑单测时必须禁用 maven build cache，否则 surefire 会被静默跳过而 `BUILD SUCCESS` 是空的。删除 `pluginCatalogTypeToEngine` 后对该符号名全仓复扫应为零命中（注意 `PluginDrivenExternalTable` 与测试注释里都提到过它，要一并改掉说法）。 + +## 七、风险与回退 + +**风险一：文案漂移。** 四道门共十余条用户可见文案，端到端用例只覆盖了其中一部分。缓解手段就是第六节的「先固化再改」，以及第三步那张边角组合清单——不要靠「跑一遍绿了」当结论，要能说出每条文案在改后由谁抛出。 + +**风险二：校验顺序被打乱。** 四道门的顺序（补名 → 名字合法 → 与目录匹配 → 子句允许）和 `analyzeEngine` 内部「先分桶后分区」的顺序都承载了具体文案。本仓库已有先例：把多阶段校验合并后丢掉优先级，导致建表用例失败。要求：不合并任何两道门，`analyzeEngine` 内两条 `throw` 位置不互换，并用一条同时触发两条检查的单测把顺序钉死。 + +**风险三：把目录初始化时机提前。** `getConnector()` 会强制初始化目录。若在 `paddingEngineName`（`:413`，四道门里最早的一道）直接用它，一个远端不可达的目录上 `CREATE TABLE` 的报错会从引擎名相关文案变成连接失败。缓解：按 5.1 用不强制初始化的读法，只在连接器字段为空时才初始化。要专门测一条：连接器为空的降级目录上建表，报错仍指向「插件未加载」。 + +**风险四：插件与引擎版本错配。** 新增的默认方法与两个枚举值都是向后兼容的（旧连接器不覆写=不支持建表，与今天的 jdbc/es 行为一致），但反过来不成立：**新连接器包配旧 FE** 会因为枚举值不存在而在读取能力集时炸类加载。这与本仓库既有的插件版本纪律一致，要在提交说明里写明「连接器插件包与 FE 必须同批部署」，并做一次插件包重部署冒烟。 + +**回退**：改动集中在一个 `fe-core` 文件加四个连接器的少量声明，没有持久化格式、没有 thrift 有线格式、没有新增用户可见语法，直接整体 revert 即可，无需数据迁移。分两个提交做更稳：第一个提交只加测试（此时全绿），第二个提交搬迁判据；出问题只回退第二个。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md`：第 4.1 节第（2）小节「`CREATE TABLE` 的四处协同改动」——本任务的来源，列出 engine 常量、type→engine switch、engine 白名单、分区/分桶允许列表这四处；同节第（1）小节是目录类型白名单的删除，与本任务同源但不同文件。附录 A 第 4 条的复核——把「四处」收窄为「三个协同编辑点」，与本文第二节一致。 +- 同一份报告第十五节的整治路线表第 10 批「建表能力下沉」——把本任务标为风险 **高**，明确要求端到端兜底且错误文案与校验优先级逐字保持；第 17.1 节「合理的本地化（不要改回去）」表格中「引擎名白名单」那一行——说明白名单本身合理、不可整体移除，只该把外部目录那一段变成连接器声明，这是本任务范围的边界依据。 +- 同目录 `tasks/07-write-down-the-design-rules.md`：能力位该放枚举还是放 provider 的分层判据；本任务新增的两个能力位属于「建表子句门」，与 `SUPPORTS_SORT_ORDER` 同族，落在枚举里。 +- `plan-doc/HANDOFF.md`：动手前先读，再对照真实代码复核本文行号。 diff --git a/plan-doc/connector-public-interface-cleanup/tasks/19-relocate-elasticsearch-specific-surface.md b/plan-doc/connector-public-interface-cleanup/tasks/19-relocate-elasticsearch-specific-surface.md new file mode 100644 index 00000000000000..98894a041f8175 --- /dev/null +++ b/plan-doc/connector-public-interface-cleanup/tasks/19-relocate-elasticsearch-specific-surface.md @@ -0,0 +1,247 @@ +# 19. 把 Elasticsearch 专有的逃生门与通用扫描节点里的 ES 分支归位 + +> **优先级**：第五优先级（中立化） ｜ **风险**：中 ｜ **前置依赖**：无 +> **影响模块**：`fe-connector-api`（删一个方法、加一个可选能力接口）、`fe-connector-es`（承接两处 ES 逻辑）、`fe-core`（净删 ES 专有分支，改一个 REST 端点的取用方式） +> **预计改动规模**：6 个主源文件 + 2 个测试文件；新增 1 个接口文件约 40 行，`fe-core` 主源净减约 8 行、净增约 12 行中立代码，`fe-connector-es` 净增约 45 行，新增单测约 120 行 +> **行号说明**：本文行号以 `7ff51a106f0` 为准，核对时以符号名为准，不要以行号为准。 + +## 一、一句话说明这个任务要解决什么 + +有两处 Elasticsearch 专有的东西长在了所有连接器共用的公共位置上：一个是所有连接器都继承的入口接口 `Connector` 上挂着一个只有 ES 会实现的 REST 透传方法；另一个是通用扫描节点 `PluginDrivenScanNode` 里还留着两段按 ES 格式名硬判的分支（EXPLAIN 打印 `ES terminate_after`、往 ES 专属 thrift 属性里塞 `limit`）。本任务把第一处摘成一个可选能力接口交给 ES 连接器实现，把第二处经既有的两个委派钩子搬进 ES 连接器，引擎侧只以中立的合成键提供三个事实（下推的 limit、过滤是否已全部下推、BE 每批行数）。 + +## 二、背景：现在的代码是怎么写的 + +### 2.1 REST 透传方法挂在入口接口上 + +`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/Connector.java:292-305`： + +```java + /** + * Execute a REST passthrough request against the underlying data source. + * + *

    /_search` 两个 ES 路径； +- 该端点在 `ESCatalogAction.java:67-70` 已经按类型名收窄：`!"es".equals(((PluginDrivenExternalCatalog) catalog).getType())` 就直接回 `badRequest("unknown ES Catalog: ...")`。 + +也就是说：路径与响应形状都是 ES 的，收窄判定在端点里，而方法本身却挂在每个连接器都继承的入口接口上，其他 7 个连接器继承到的是一个「调用即抛异常」的方法（本仓库共 8 个 `Connector` 实现：es / hive / hudi / iceberg / jdbc / maxcompute / paimon / trino）。 + +同一个 `Connector` 接口里已经有现成的可选能力写法（`Connector.java:339-349`），javadoc 里还明确写了不要用 `instanceof`： + +```java + /** + * Returns this connector's incremental metadata-change source, or {@code null} if it has none. + * A capability-probe getter ... never via {@code instanceof}. ... + */ + default ConnectorEventSource getEventSource() { // :347 + return null; + } +``` + +引擎侧对应的取用方式在 `fe/fe-core/src/main/java/org/apache/doris/datasource/MetastoreEventSyncDriver.java:132`（`getConnector().getEventSource()` 判空）。 + +### 2.2 通用扫描节点里的两段 ES 分支 + +文件：`fe/fe-core/src/main/java/org/apache/doris/datasource/scan/PluginDrivenScanNode.java`。 + +第一段，EXPLAIN 输出（`:559-564`）： + +```java + // Show ES terminate_after optimization when limit is pushed to ES + if (limit > 0 && conjuncts.isEmpty() + && "es_http".equals(props.get(PROP_FILE_FORMAT_TYPE))) { + output.append(prefix).append("ES terminate_after: ") + .append(limit).append("\n"); + } +``` + +第二段，往 thrift 参数里塞 ES 属性（`:1815-1836`）： + +```java + public void createScanRangeLocations() throws UserException { + super.createScanRangeLocations(); + ConnectorScanPlanProvider scanProvider = resolveScanProvider(); + if (scanProvider != null) { + Map props = getOrLoadScanNodeProperties(); + onPluginClassLoader(scanProvider, () -> { + scanProvider.populateScanLevelParams(params, props); // :1823 + return null; + }); + } + pruneConjunctsFromNodeProperties(); // :1827 + // Push down limit to ES via terminate_after optimization. ... + if (limit > 0 && limit <= sessionVariable.batchSize && conjuncts.isEmpty() + && params.isSetEsProperties()) { // :1832-1833 + params.getEsProperties().put("limit", String.valueOf(limit)); + } + } +``` + +几个已核实的关键事实： + +1. `"es_http"` 这个格式名是 ES 连接器自己写进扫描节点属性的（`EsScanPlanProvider.java:184` 的 `nodeProps.put("file_format_type", "es_http")`，以及 `EsScanRange.java:91`）； +2. `es_properties` 里的 `"limit"` 键是 BE 契约：`be/src/format/table/es/es_scan_reader.h:46` 的 `KEY_TERMINATE_AFTER = "limit"`，被 `es_scan_reader.cpp:79` 与 `es_scroll_query.cpp:123` 读取，拼成 ES 的 `terminate_after=` 查询串。这个字符串不能改； +3. `params.setEsProperties(...)` 本来就是 ES 连接器自己做的（`EsScanPlanProvider.java:371`），也就是引擎在 `:1834` 是往连接器刚设进去的那张 map 里补写一个键； +4. 两个承接钩子都已存在并已被 ES 实现：`ConnectorScanPlanProvider.java:474 populateScanLevelParams` / `:490 appendExplainInfo`，ES 侧实现在 `EsScanPlanProvider.java:362` 与 `:410`； +5. 引擎向连接器传递「引擎侧事实」的合成键机制已有先例：`PluginDrivenScanNode.java:132-146` 定义了 `__native_read_splits` / `__total_read_splits` / `__explain_verbose` 三个键，`:538-543` 在委派前拷一份属性 map 注入，paimon 连接器按字面量消费并有单测锚定（`PaimonScanExplainTest.java:63` 等）； +6. **`conjuncts.isEmpty()` 的时机是有讲究的**：`:1832` 读到的 `conjuncts` 是 `:1827` 剪枝**之后**的，剪枝逻辑（`pruneConjunctsFromNodeProperties`，`:1873-1882`）会把因为含 CAST 而从未交给连接器的谓词**保留**下来，所以「conjuncts 空」等价于「所有过滤都真的被连接器接走了」。这是正确性判据，不是顺手写的条件； +7. 同一个文件在 `:490-499` 自己写下了这条规则：`NO source-name branch belongs in this generic node ... Connector-SPECIFIC EXPLAIN stays delegated to ConnectorScanPlanProvider.appendExplainInfo`。 + +## 三、为什么这是个问题 + +**违反的原则**：通用接口层与通用扫描节点里禁止出现数据源专有代码。第二处尤其明显——违规代码和写着「这里不许有源名分支」的注释在同一个文件里相隔 60 行。 + +**真实后果**： + +- 通用节点里硬编码了某个连接器的格式标签 `"es_http"` 与某个连接器的 thrift 字段 `es_properties`。任何一个新连接器想要「LIMIT 提示」这类能力，今天都必须回到 `fe-core` 加一段 `"xxx_http".equals(...)` 分支——这正是本次整治要终结的模式； +- 一半判据在引擎、一半渲染在引擎，导致两半已经不一致：EXPLAIN 那段（`:560`）**没有** `limit <= sessionVariable.batchSize` 这个判据，而真正下推那段（`:1832`）有。于是当 `batch_size` 小于 LIMIT 时，用户在 EXPLAIN 里看到 `ES terminate_after: 5000`，实际却没有任何 `limit` 被发给 BE。这是既有缺陷，不是本任务引入的（本任务按原样搬迁，见第七节与最后的待拍板问题）； +- `Connector` 那个方法让 7 个与 ES 无关的连接器都继承到一个「一调用就抛 `UnsupportedOperationException`」的方法，能力的有无只能靠异常发现，而不是像 `getEventSource()` 那样能判空探测。 + +## 四、用一个最小例子说明 + +一条最普通的 ES 查询： + +```sql +select * from es_catalog.my_db.my_index limit 5; +``` + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +|---|---|---| +| `... limit 5`，然后看 `EXPLAIN` | 通用扫描节点先问连接器要 ES 的那几行（`ES index:` 等），随后自己判断 `file_format_type == "es_http"`，再自己打印 `ES terminate_after: 5` | 引擎只告诉连接器两个中立事实：这个扫描的 LIMIT 是 5、过滤已全部下推；`ES terminate_after: 5` 这一行由 ES 连接器自己打印 | +| `... limit 5` 真正执行 | ES 连接器先把 `es_properties` 设进 thrift，引擎随后往这张 map 里补一个 `limit=5` | ES 连接器在设 `es_properties` 时自己决定要不要加 `limit=5`（引擎额外告诉它 BE 每批行数是多少） | +| `curl '.../rest/v2/api/es_catalog/get_mapping?catalog=es_catalog&table=my_index'` | 端点先判 `type == "es"`（保留），再调所有连接器都继承的 `Connector.executeRestRequest` | 端点仍先判 `type == "es"`，再取 `getRestPassthrough()`，只有 ES 连接器返回非空 | + +再换个角度：**假设我要新增一个连接器 X，它也想在 EXPLAIN 里报告自己把 LIMIT 下推给了远端**。今天我必须打开 `fe-core` 的 `PluginDrivenScanNode`，在 `:559` 旁边加一段 `"x_native".equals(props.get("file_format_type"))` 的分支；改完之后，`fe-core` 就多知道了一个连接器的格式名。本任务做完之后，我什么公共代码都不用碰：三个合成键对每个连接器都注入，我在自己的 `appendExplainInfo` 里读就行。 + +## 五、解决方案 + +### 5.1 目标状态 + +**（一）REST 透传变成可选能力接口。** 新增 `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/rest/ConnectorRestPassthrough.java`： + +```java +/** A connector that can proxy an HTTP REST request to its underlying source. */ +public interface ConnectorRestPassthrough { + /** + * @param path 相对路径（由调用端按该数据源的 REST 形状拼好） + * @param body 请求体，GET 风格请求可为 null + * @return 响应体原文 + */ + String executeRestRequest(String path, String body); +} +``` + +`Connector.java` 删掉 `executeRestRequest`（`:292-305`），换成与 `getEventSource()` 同形的能力探针： + +```java + /** + * Returns this connector's REST passthrough capability, or {@code null} if it has none. + * A capability-probe getter (mirrors {@link #getEventSource()}): the caller probes for null, + * never via {@code instanceof}. Default null, so no connector inherits a throwing method. + */ + default ConnectorRestPassthrough getRestPassthrough() { + return null; + } +``` + +`EsConnector` 改成 `implements Connector, ConnectorRestPassthrough`，保留原来的一行方法体，另加 `getRestPassthrough() { return this; }`。 + +`ESCatalogAction` 把内部 `handleRequest` 的函数参数从 `BiFunction` 换成 `BiFunction`，在既有的 `"es"` 类型判定之后取一次能力、判空后再调；两个端点的 lambda 从 `((PluginDrivenExternalCatalog) catalog).getConnector().executeRestRequest(...)` 简化为 `rest.executeRestRequest(...)`。**`"es".equals(...)` 那句一个字不动。** + +**（二）扫描节点的两段 ES 分支搬进 ES 连接器。** `PluginDrivenScanNode` 新增三个合成键（形态、注释风格照抄 `:132-146`）： + +```java + private static final String PUSHDOWN_LIMIT_KEY = "__pushdown_limit"; + private static final String ALL_CONJUNCTS_PUSHED_KEY = "__all_conjuncts_pushed"; + private static final String SESSION_BATCH_SIZE_KEY = "__session_batch_size"; +``` + +两条委派路径都注入这三个键（EXPLAIN 路径在 `:538` 的 `explainProps` 上追加；thrift 路径新拷一份 map）。为此 `createScanRangeLocations` 里必须把 `pruneConjunctsFromNodeProperties()` 提到 `populateScanLevelParams` 委派**之前**，因为「过滤是否已全部下推」这个事实只有剪枝后才成立。 + +顺序调换的安全性依据（已逐个核实）：现存五个 `populateScanLevelParams` 实现——`HiveScanPlanProvider.java:449`、`HudiScanPlanProvider.java:409`、`IcebergScanPlanProvider.java:1777`、`PaimonScanPlanProvider.java:1355`、`EsScanPlanProvider.java:362`——都只按固定键读传入的属性 map 并写 `params`，没有任何一个读 `conjuncts`；而 `pruneConjunctsFromNodeProperties` 只改 `conjuncts` 并读已缓存的属性结果。因此交换顺序对 thrift 参数逐字节不变。 + +ES 连接器侧：`EsScanPlanProvider.populateScanLevelParams` 在把 `esProperties` 设进 params 之前，按 `limit > 0 && batchSize > 0 && limit <= batchSize && "true".equals(allPushed)` 决定是否 `esProperties.put("limit", ...)`；`appendExplainInfo` 在现有三行 ES 输出之后，按 `limit > 0 && "true".equals(allPushed)` 追加 `ES terminate_after: `（**故意不加 batch 判据**，逐字保留既有行为，并写 ATTN 注释说明这一不对称是既有状态）。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +| `fe-connector-api/.../connector/api/rest/ConnectorRestPassthrough.java` |

`PluginDrivenScanNodeExplainStatsTest` 的纯静态断言写法） | + +### 5.3 明确不要顺手做的事 + +- **不要中立化 `ESCatalogAction` 里的 `"es".equals(...)` 判定。** 这个端点本身就是 ES 兼容 API（路径拼 `/_mapping`、`/_search`，响应形状是 ES 的），按类型收窄是正确边界；一旦中立化，就等于把这个端点开给所有声明了 REST 直通能力的连接器，白扩攻击面。 +- **不要动 `mapFileFormatType` 里的 `case "es_http": return TFileFormatType.FORMAT_ES_HTTP;`（`PluginDrivenScanNode.java:1970`）。** 那是格式名到 thrift 枚举的通用查表，和 `parquet` / `orc` / `text` 并列，thrift 枚举还受有线格式约束；它不是源专有分支。 +- **不要顺手修 EXPLAIN 与实际下推的 batch 判据不一致**（第三节第二条）。本任务的验收基线是 EXPLAIN 文本逐字不变；要修就另立一项，同时改 `external_table_p2` 的用例并想清楚 `batch_size` 变化时的用户预期。 +- **不要顺手给 `ESCatalogAction` 补插件类加载器钉扎**。当前 REST 线程直接调进插件、未 pin TCCL，这是既有状态，与本任务无关；要修单独立项评估。 +- **不要动 `pruneConjunctsFromNodeProperties` 的剪枝算法本身**（含 CAST 谓词保留那段），本任务只调它的调用位置。 +- **不要为「通用节点里不许出现源名」这条不变量加 shell/正则门禁**。本仓已有结论：这类门禁只适合存在性与前缀类不变量，判断语言语义时误报比漏报更毒。用注释 + 单测 + 评审。 + +## 六、怎么验证 + +**ES 连接器单测**（`EsScanPlanProviderTest`，现有 `testAppendExplainInfoShowsEsIndex` 就是模板）： + +1. `populateScanLevelParams`：属性含 `__pushdown_limit=5`、`__session_batch_size=1024`、`__all_conjuncts_pushed=true` → `params.getEsProperties().get("limit")` 等于 `"5"`。这条同时锚定 BE 契约字符串 `"limit"`； +2. `__all_conjuncts_pushed=false` → `es_properties` 里**没有** `limit` 键（这是正确性用例：过滤没全下推却限量，会少返回行）； +3. `__pushdown_limit=5000`、`__session_batch_size=1024` → 没有 `limit` 键； +4. 三个键都缺失（老调用方/纯单测 map）→ 没有 `limit` 键； +5. `appendExplainInfo`：`__pushdown_limit=5` + `__all_conjuncts_pushed=true` → 输出**逐字**含 `ES terminate_after: 5\n`（前缀、冒号后一个空格）；`__all_conjuncts_pushed=false` 或键缺失 → `notContains "ES terminate_after"`。 + +**变异验证**（改实现应让上述用例变红）：把用例 1 的比较写成 `limit >= batchSize` → 用例 3 失败；去掉 `__all_conjuncts_pushed` 判据 → 用例 2、5 的负例失败；把 `"limit"` 键名写成 `"terminate_after"` → 用例 1 失败。 + +**引擎侧单测**（新增类，照 `PluginDrivenScanNodeLimitStripTest` 的纯静态写法）：断言注入辅助方法在 `limit=-1` / `limit=5`、`allPushed` 真假、`batchSize` 各取值下写出的键值字符串正确，且键名字面量与 ES 连接器侧一致（两侧各写死同一批字面量，这与 paimon 现有合成键的做法同构）。剪枝先于委派这一顺序无法用纯静态方法覆盖，用 ATTN 注释写清依据（5.1 节列的五个实现均不读 `conjuncts`），交评审把关。 + +**编译门禁**（最强单一信号，必须全反应堆含测试源）： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T 1C test-compile +``` + +不得加任何跳过测试编译的参数。这一步能一次性抓出「有没有别的模块还在调 `Connector.executeRestRequest`」。 + +**跑单测**（必须禁用构建缓存，否则 surefire 会被静默跳过）： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -Dmaven.build.cache.enabled=false \ + -pl fe-connector/fe-connector-es,fe-core -am test \ + -Dtest='EsScanPlanProviderTest,PluginDrivenScanNode*Test' +``` + +**端到端回归**：`regression-test/suites/external_table_p2/es/test_es_query_predicate_correctness.groovy:94-135` 六处断言（`contains "ES terminate_after: 5"` / `"3"`、`notContains "ES terminate_after"`，ES 7 与 ES 8 各三处）必须仍通过。这些断言用 `contains`，对行的相对位置不敏感——本任务会让 `ES terminate_after` 从 `pushdown agg=` 之后移到 ES 其它几行之后（即 `pushdown agg=` 之前）。已核实仓库内没有把整段 EXPLAIN 存成 golden 文件的 ES 用例（`grep -rn terminate_after regression-test --include=*.out` 无命中），所以只有这一个 p2 套件受影响。该套件需要 ES 7/8 容器，本地无集群时须显式标注为「待集群验证」，不得当作已通过。 + +**REST 端点手工验证**（无自动化覆盖，`ESCatalogAction` 在仓库里既无单测也无回归用例）：部署后各调一次 `get_mapping` 与 `search`，确认响应体与改动前一致；另外用一个非 ES 目录名调一次，确认仍返回 `unknown ES Catalog`。 + +## 七、风险与回退 + +- **EXPLAIN 文本漂移（主要风险）**：`ES terminate_after: ` 这个前缀连空格都不能变，否则 p2 用例失败。对策是连接器单测断言整行，且搬迁时用复制粘贴而不是重写字符串拼接。 +- **行位置变化**：如上所述，这一行在 EXPLAIN 里的位置会前移。当前所有断言都是包含式，风险可接受；但若后续有人加了整段比对，会暴露。 +- **剪枝与委派顺序调换**：依据已在 5.1 列出（五个实现都不读 `conjuncts`）。若担心，可分两个 commit：先只搬 EXPLAIN 那半（不需要调顺序），确认 p2 通过后再搬 thrift 那半。 +- **合成键字符串两侧漂移**：引擎与 ES 各自定义常量，靠单测里硬编码字面量锚定——与 paimon 现有三个合成键同风险同对策。 +- **新旧版本混搭部署**：删掉 `Connector.executeRestRequest` 后，若用旧的 ES 插件包配新 `fe-core`，插件里的 `EsConnector` 多出一个不再属于任何接口的方法（运行期无害），但 `getRestPassthrough()` 会返回 null，两个 REST 端点会返回 `badRequest` 而不是原来的 500。插件与 FE 同版本部署是既有约定，此处只需在提交说明里写明。 +- **一个需要用户拍板的取舍**：EXPLAIN 那半缺少 `limit <= batch_size` 判据（第三节第二条），会让用户在 `batch_size` 较小时看到一个并未真正生效的 `ES terminate_after`。本文默认**逐字保留**这个不一致（验收基线是文本不变）；若允许在同一轮里把连接器侧 EXPLAIN 判据补齐成与实际下推一致，则需接受 `batch_size` 小于 LIMIT 时 EXPLAIN 输出发生变化（现有 p2 用例的 `limit 5` / `limit 3` 远小于默认 `batch_size`，不会变红）。 +- **回退**：三处改动彼此独立（REST 能力接口 / EXPLAIN 一行 / `es_properties` 的 `limit`）。建议至少分两个 commit：一个只做 REST 能力接口，一个只做扫描节点归位，便于单独 revert。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md`：附录 A.2「公共模块里的数据源专有语义」下第 18 条——通用扫描节点里的 ES 分支（EXPLAIN 的 `terminate_after` 与 `esProperties` 的 limit），严重度高；第 19 条——`executeRestRequest` 这个 ES

`region IN ('__HIVE_DEFAULT_PARTITION__')` 刷新。分区名一旦进了视图定义、物化视图分区、以及 BE 的 `columns_from_path` 字节，就是对外可见的持久化标识。 + +**另外一件容易搞混的事**：`ConnectorPartitionInfo` 的分区空值标志（结构化布尔位）与这个字符串哨兵**不是替代关系**。`PluginDrivenMvccExternalTable.java:308-323` 的 javadoc 已经写清了分工：标志服务于 FE 侧构造带类型的 `NullLiteral`（否则 INT / DATE 分区列会在解析哨兵字符串时抛异常、整个分区被静默丢弃，表被误报成未分区），哨兵服务于分区名身份与 BE 列路径解析的字节兼容。同一段 javadoc 还点明「hive 与 paimon 渲染出**同一个**哨兵字符串但空值语义不同，所以 fe-core 不能靠字符串比较判空」。 + +## 三、为什么这是个问题 + +三件事，都属于「命名与归属」层面，不是正确性缺陷： + +1. **中立模块里挂着数据源品牌名**。`fe-connector-api` 是给所有连接器（包括第三方自研连接器）看的公共契约面，`HIVE_DEFAULT_PARTITION` 是里面唯一一个带数据源品牌的字符串常量。一个写 paimon 连接器的人被迫引用一个叫「hive 默认分区」的常量来表达「Doris 规范的空分区名」，读代码的人会以为自己走错了模块。 + +2. **名字通用、语义专有的方法会把人骗进坑里**。`isNullPartitionValue(String)` 这个签名看不出任何限定，实际语义是「hive/hudi 的目录式分区里，`null`、`__HIVE_DEFAULT_PARTITION__`、字面量 `\N` 三者都算空」。对类型化分区值的连接器（paimon 的分区值本来就是 Java 类型，`\N` 是合法的字符串数据）用它就会**把真实数据判成 NULL**。现状是靠三处注释（`HiveScanRange.java:159-161`、`HiveConnectorMetadata.java:1198-1200`、`PaimonScanRange.java:281-283`）挡住的——需要三条注释反复警告「别用公共方法」，说明这个方法放错了地方。下一个连接器作者不会先读别人的注释。 + +3. **同一个字面量三处可写、两处已写**。公共模块和 `fe-core` 各有一份活定义，谁改一处都不会让另一处编译失败。这也是为什么**不能**把常量下沉到 hive 连接器：引擎自己的 `FilePartitionUtils` 在用它（引擎不能 import 插件），非 hive 的 paimon 也在主动往它归一，下沉的结果是从两份变三份。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器 X，它的分区值是类型化的（跟 paimon 一样），空分区的目录名是 ``，而且它有一列的真实数据里就存着字符串 `\N`。 + +| 我今天读到什么 | 我大概率会怎么写 | 实际发生什么 | +|---|---|---| +| 中立公共模块里有 `ConnectorPartitionValues.normalize(values)`，名字通用，附近没有任何限定说明 | 直接调它，一次拿到值列表和空值标志列表 | 那一行真实数据 `\N` 被判成 SQL NULL，查询静默少行；要发现这点，得先读到 hive 和 paimon 源码里的三条「别用它」注释 | +| 我想表达「这个分区是空值」的规范分区名 | 找不到中立名字，只能 `import ...HIVE_DEFAULT_PARTITION` | 我的连接器里出现了一个 hive 品牌常量，评审要花时间解释「这不是 hive 专用」 | + +改完之后：公共模块里只剩一个中立命名的常量（值不变），旁边有一句 javadoc 说明它是「Doris 规范的空分区名、字节冻结」；那个会误伤的 `normalize` 不再出现在公共面上，它连同 `\N` 语义一起留在唯一真正需要它的 hudi 连接器里。连接器 X 的作者拿不到那把误伤的刀，只能按自己的类型化语义自己填空值标志——这正是 hive、paimon、iceberg 现在各自的做法。 + +## 五、解决方案 + +### 5.1 目标状态 + +公共模块只保留常量，签名草案： + +```java +/** + * Doris 规范的分区名相关常量。 + * + *

    NULL_PARTITION_NAME 是「这个分区列的值是真正的 NULL」在**分区名**里的规范写法。它的字面量 + * 沿用 hive 的历史取值，且**必须逐字冻结**：分区名会进入视图 / 物化视图定义、partition_values() + * 表函数结果，以及 BE 的 columns_from_path 字节。连接器若有自己的空分区名（如 paimon 的 + * partition.default-name），应在渲染分区名时归一到本常量。 + * + *

    注意：本常量不能替代 ConnectorPartitionInfo 的分区空值标志。标志服务于 FE 侧构造带类型的 + * NullLiteral，哨兵服务于分区名身份；「值是否为空」必须由连接器用标志声明，fe-core 不做字符串比较。 + */ +public final class ConnectorPartitionValues { + + public static final String NULL_PARTITION_NAME = "__HIVE_DEFAULT_PARTITION__"; + + /** @deprecated 改用 {@link #NULL_PARTITION_NAME}；本别名仅为外部连接器保留一轮。 */ + @Deprecated + public static final String HIVE_DEFAULT_PARTITION = NULL_PARTITION_NAME; + + private ConnectorPartitionValues() { + } +} +``` + +hudi 一侧：`normalize` / `Normalized` / `\N` 常量全部消失，改成 `HudiScanRange.populateRangeParams` 里的一段内联循环（与 hive、paimon、iceberg 三家现在的写法一致，不新增类、不新增抽象）： + +```java +private static final String HUDI_NULL_PARTITION_VALUE = "\\N"; // hudi 目录式分区的空值渲染，保持发给 BE 的字节不变 +... +String value = entry.getValue(); +// hudi 的分区值来自路径目录名：Java null、规范空分区名、以及历史上的 "\N" 都算空。 +// 这三条只对目录式分区成立，所以留在 hudi 里，不放在中立公共模块（hive 与 paimon 都刻意绕开它）。 +boolean nullValue = value == null + || ConnectorPartitionValues.NULL_PARTITION_NAME.equals(value) + || HUDI_NULL_PARTITION_VALUE.equals(value); +pathKeys.add(entry.getKey()); +pathValues.add(nullValue ? HUDI_NULL_PARTITION_VALUE : value); +pathIsNull.add(nullValue); +``` + +这段与原 `normalize` 逐字等价：原实现对 `null` 与规范空分区名都渲染成 `\N`，对字面量 `\N` 原样保留（也是 `\N`）并置空值位为 true——新代码三种情况都渲染 `\N`、空值位 true，发给 BE 的字节完全一致。注意 hudi 的空值渲染是 `\N` 而 hive / paimon / iceberg 是空串（`HiveScanRange.java:175`、`PaimonScanRange.java:287`），**本任务不统一这个差异**（见 5.3）。 + +`fe-core` 一侧：删掉 `TablePartitionValues.java:47` 那份重复定义，两个使用点改为引用公共常量。 + +### 5.2 改动清单 + +| 文件 | 做什么 | +|---|---| +| `fe-connector-api/.../scan/ConnectorPartitionValues.java` | 新增中立常量 `NULL_PARTITION_NAME`（值不变）；旧名保留为 `@Deprecated` 别名并指向新常量；补类级 javadoc（写清「值冻结」「与空值标志的分工」）；删除 `NULL_PARTITION_VALUE`、`normalize`、`isNullPartitionValue`、`normalizePartitionValue`、嵌套类 `Normalized`（共约 35 行） | +| `fe-connector-hudi/.../HudiScanRange.java:247-251` | 用 5.1 的内联循环替换 `normalize` 调用；加 `HUDI_NULL_PARTITION_VALUE` 私有常量与 WHY 注释；`import` 保留（仍要引用中立常量） | +| `fe-connector-hive/.../HiveScanRange.java:173` | 常量引用改新名；顺手把 :160 那句「不要用 `ConnectorPartitionValues.normalize`」的注释改成指向 hudi 内部实现（否则注释指向一个已不存在的符号） | +| `fe-connector-hive/.../HiveConnectorMetadata.java:1206` | 常量引用改新名；:1200 提到 `isNullPartitionValue` 的注释同上改写 | +| `fe-connector-paimon/.../PaimonConnectorMetadata.java:1263`（及 :1245 注释） | 常量引用与注释里的符号名改新名 | +| `fe-connector-paimon/.../PaimonScanRange.java:281-283` | 注释里提到 `normalize` 的部分改写（无代码引用） | +| `fe-core/.../datasource/TablePartitionValues.java:47,162` | 删掉重复的常量定义，:162 改为引用 `ConnectorPartitionValues.NULL_PARTITION_NAME`（fe-core 主源净删一行，不新增数据源相关代码） | +| `fe-core/.../tablefunction/MetadataGenerator.java:2067` | 引用改为公共常量；去掉不再需要的 `TablePartitionValues` import（若该 import 还有别的用途则保留） | +| `fe-core` 测试：`PluginDrivenMvccExternalTableTest.java`、`ListPartitionItemTest.java` | 9 处 `TablePartitionValues.HIVE_DEFAULT_PARTITION` 引用改为公共常量（`PluginDrivenMvccExternalTableTest` 8 处：287 / 291 / 297 / 310 / 319 / 329 / 335 / 346 行；`ListPartitionItemTest` 1 处：64 行）。纯改名，断言语义不动，但处数比看上去多，别漏改 | +| `fe-connector-paimon` / `fe-connector-hive` 测试中引用旧常量名的用例 | 改新名（`PaimonConnectorMetadataPartitionTest` 5 处等；写死字面量的用例不必改） | +| **新增** `fe-connector-hudi/src/test/java/.../HudiScanRangePartitionValuesTest.java` | 见第六节 | +| **新增** `fe-connector-api/src/test/java/.../scan/ConnectorPartitionValuesTest.java` | 见第六节 | + +### 5.3 明确不要顺手做的事 + +- **不要改字符串值，也不要「顺手」把 `__HIVE_DEFAULT_PARTITION__` 改成看起来更中立的字面量。** 它是持久化标识：视图 / 物化视图定义、`partition_values()` 表函数输出、BE 列路径解析都按它对齐（证据见第二节的两个回归套件）。本任务改的只是 Java 侧的符号名。 +- **不要把常量下沉到 hive 连接器。** 引擎的 `FilePartitionUtils.java:143` 在用它，而引擎不能 import 插件；paimon 也在主动往它归一。下沉只会让同一个字面量变成三份。 +- **不要试图用结构化空值标志「取代」哨兵、也不要反向取代。** 两者服务的对象不同（第二节最后一段）。任何「统一成一套」的提议都会打破 FE 侧类型化空值或 BE 侧字节兼容中的一个。 +- **不要顺手统一 hudi 的 `\N` 与 hive / paimon 的空串。** 这两个渲染都是发给 BE 的 `columns_from_path` 值，理论上空值位为 true 时 BE 会忽略字符串，但这属于行为变更、需要端到端验证，与本次的命名与归属整治无关。要做就单独立项。 +- **不要重命名 `ConnectorPartitionValues` 这个类**（哪怕它瘦到只剩一个常量）。类改名会牵动全部连接器的 import，收益为零。 +- **不要顺手清理 `TablePartitionValues` 这个类**（它在 `PluginDrivenExternalTable.getNameToPartitionItems` 的活路径上）。本任务只删它那一行重复的常量定义。 +- **不要为「公共模块里不许出现数据源品牌字符串」写 shell 或正则门禁。** 本仓库已有结论：这类门禁只适合存在性与前缀类不变量，去校验「哪个字符串算品牌名」必然误报，而误报会挡住合法构建。 + +## 六、怎么验证 + +**新增单测一：hudi 分区值渲染（这是本任务唯一有行为风险的地方）** +`fe-connector-hudi/src/test/java/org/apache/doris/connector/hudi/HudiScanRangePartitionValuesTest.java`，用 `new HudiScanRange.Builder().partitionValues(...)` 构造后调 `populateRangeParams(new TTableFormatFileDesc(), new TFileRangeDesc())`（现有 `HudiScanRangeTest` 就是这个套路），断言四种输入的 `columns_from_path` / `columns_from_path_is_null`： + +| 输入分区值 | 断言的值 | 断言的空值位 | +|---|---|---| +| `"2024-01-01"`（普通值） | `"2024-01-01"` | `false` | +| `"__HIVE_DEFAULT_PARTITION__"` | `"\N"` | `true` | +| Java `null` | `"\N"` | `true` | +| 字面量 `"\N"` | `"\N"` | `true` | + +再加一条：分区值为空 map 时，三个 `columns_from_path*` 字段一个都不设置（保持现状：现有代码在 `partValues` 空时整段跳过）。测试注释必须写清 WHY——**这四行断言就是「下沉不改字节」的证据**，hudi 的分区值来自路径目录名，所以这三条空值判定成立；hive / paimon 用的是别的判定，所以这段逻辑不能回到公共模块。 + +**变异验证（必须做，写进测试注释）**：把 `pathValues.add(nullValue ? HUDI_NULL_PARTITION_VALUE : value)` 改成 `pathValues.add(value)` → 第 3 行（Java `null`）必须变红；把 `nullValue` 的第三个条件（字面量 `\N`）删掉 → 第 4 行必须变红。两条各自能被对应的错误写法打红，才算钉住了「与原 `normalize` 逐字等价」。 + +**新增单测二：常量值冻结** +`fe-connector-api/src/test/java/org/apache/doris/connector/api/scan/ConnectorPartitionValuesTest.java`，两条断言：`NULL_PARTITION_NAME` 逐字等于 `"__HIVE_DEFAULT_PARTITION__"`；过时别名与新常量是同一个值。注释写清 WHY：改这个字面量会让已持久化的视图 / 物化视图分区与 BE 列路径解析对不上。这是一条「不许有人顺手美化字面量」的护栏测试，不是行为快照。 + +**回归既有用例**：`fe-core` 的 `PluginDrivenMvccExternalTableTest`、`ListPartitionItemTest`、`BrokerUtilTest`（后者覆盖 `FilePartitionUtils.parseColumnsFromPath`），以及 `fe-connector-paimon` 的 `PaimonConnectorMetadataPartitionTest`、`fe-connector-hive` 的 `HiveScanRangePartitionValuesTest` /

+风险低，改动分成三块，每块的失败模式都很好识别： + +1. **改名**：编译期强制，改漏就编不过；过时别名保证了本仓库之外按旧名编译的连接器仍能通过。 +2. **hudi 下沉**：唯一有运行时语义的部分，但新代码与原 `normalize` 逐字等价，由第六节的四行断言加两次变异验证钉住。真出问题的表现是 hudi 分区表某一列的空值行读成字符串 `\N` 或反之——回退只需把那段循环换回 `ConnectorPartitionValues.normalize`（方法从 git 历史取回即可）。 +3. **fe-core 去重**：把一份重复的字面量换成引用，无行为变化。 + +需要留意的一点：`@Deprecated` 别名会让编译器对仍然引用旧名的代码报 deprecation 警告。本仓库内所有引用都在本任务里一次改完，因此不会新增警告；如果 CI 打开了「警告即错误」，那就必须确保改全（`grep -rn "HIVE_DEFAULT_PARTITION"` 应只剩公共模块的别名声明、以及测试与注释里写死字面量的地方）。 + +回退：三块互不依赖，可以单独 revert。 + +## 八、相关背景 + +- 调研报告 `plan-doc/connector-public-interface-cleanup/audit-report.md`： + - 第 8.1 节的清单表格中 `ConnectorPartitionValues.HIVE_DEFAULT_PARTITION` 那一行——本任务对应的那条建议：常量不删不改值、只做中立化命名 + 保留旧名别名一轮，三个归一方法下沉到唯一的生产调用方； + - 附录

`fe/fe-core/src/main/java/org/apache/doris/datasource/scan/PluginDrivenScanNode.java`，键定义在 :127-130，全部是 `private`： + +```java +/** Scan node property keys (shared with connector plugins). */ +private

`parquet`/`orc`/`text`/`csv`/`json`/`avro`/`es_http`，其余一律落到 `FORMAT_JNI` | +| `path_partition_keys` | `:588` | 逗号切分后作为 `getPathPartitionKeys()`，决定哪些列不从文件里解码 | +| `location.` 前缀 | `:788-789` | 剥掉前缀后作为 `getLocationProperties()`，即 BE 访问存储用的配置 | +| `hive.text.` 前缀 | `:799-863` | 组装 `TFileAttributes`；实际读 12 个后缀：`serde_lib`、`skip_lines`、`column_separator`、`line_delimiter`、`mapkv_delimiter`、`collection_delimiter`、`escape`、`null_format`、`enclose`、`trim_double_quotes`、`is_json`、`openx_ignore_malformed` | +| `query` | `:447` | 打进 EXPLAIN 的 `QUERY:` 行。**这一个连 `private` 常量都没有，是裸字面量** | + +反方向（引擎写、连接器读）还有三个合成键，`PluginDrivenScanNode.java:139-146` 定义、`PaimonScanPlanProvider.java:202-208` **按字节复制了一份**，两边注释都写着「keys are byte-identical … so the inject/consume sides stay in lockstep」：`__native_read_splits`、`__total_read_splits`、`__explain_verbose`。这是靠注释维持的字符串对齐，编译器完全不参与。 + +### 2.3 连接器一侧的现状 + +- hive：`HiveScanPlanProvider.java:82-84` 自己又定义了一份 `PROP_FILE_FORMAT_TYPE` / `PROP_PATH_PARTITION_KEYS` / `PROP_LOCATION_PREFIX`（值与引擎逐字相同）；`hive.text.` 前缀在 `HiveTextProperties.java:87`。 +- hudi：`HudiScanPlanProvider.java:316`、`:317`、`:322`、`:331`、`:341`、`:352` 全是裸字面量。 +- iceberg：`IcebergScanPlanProvider.java:1554`、`:1572`、`:1588`、`:1599` 全是裸字面量。 +- paimon：`PaimonScanPlanProvider.java:751`、`:752`、`:765`、`:827`、`:839` 全是裸字面量。 +- jdbc：`JdbcScanPlanProvider.java:185` 写 `props.put("query", querySql)`。 +- es：`EsScanPlanProvider.java:184` 写 `"file_format_type"`；它自己那批键（`query_dsl` 等）有常量，在 :66-74。 + +顺带核实到两个**只写不读**的键：`table_format_type`（`PaimonScanPlanProvider.java:752`、`HudiScanPlanProvider.java:317` 写入，全仓库没有任何 `get` 端）与 `_table_name`（`EsScanPlanProvider.java:187` 写入，无读端）。它们不属于本任务范围（见 5.3）。 + +### 2.4 两个返回面 + +同一份属性还有第二个返回面，`ConnectorScanPlanProvider.java:455`： + +```java +default ScanNodePropertiesResult getScanNodePropertiesResult(...) { + return new ScanNodePropertiesResult(getScanNodeProperties(session, handle, columns, filter)); +} +``` + +核实结论（比调研报告更精确）：**引擎只调这个包装面**（`PluginDrivenScanNode.java:1928`），**6 个**连接器覆写了 `Map` 面（es :156、hive :377、hudi :306、iceberg :1535、jdbc :161、paimon :739），其中 es 同时覆写了包装面（:165），所以真正靠默认委派生效的是**另外 5 个**。这**不是**两套竞争机制——包装面的默认实现显式调用了 `Map` 面。但由此产生一个静默陷阱：一个连接器如果两个面都覆写而实现不一致，`Map` 面的返回值会被彻底丢弃且不报错。接口 javadoc 现在没有任何一句话提醒这件事。 + +包装对象本身 `ScanNodePropertiesResult.java:46` 与 `:60` 是两个只差一个参数的构造器，一参版把 `hasConjunctTracking` 置 `false`、两参版置 `true`——**「有没有下推追踪」这个布尔位是靠「调用方选了哪个构造器」隐式编码的**，读代码的人看 `new ScanNodePropertiesResult(props)` 完全看不出自己顺带声明了「不做谓词裁剪」。全仓库只有 3 个构造点：`ConnectorScanPlanProvider.java:460`、`PluginDrivenScanNode.java:1932`、`EsScanPlanProvider.java:220`。 + +### 2.5 `getSerializedTable(Map)` 这条弯路 + +`ConnectorScanPlanProvider.java:520`： + +```java +default String getSerializedTable(Map nodeProperties) { + return null; +} +``` + +唯一实现是 `PaimonScanPlanProvider.java:1763-1765`：`return properties.get("paimon.serialized_table")`——而这个键正是它自己在 `:770` 写进属性表的。引擎侧 `PluginDrivenScanNode.java:1803-1813` 覆写了 `FileQueryScanNode.getSerializedTable()`（基类定义在 `FileQueryScanNode.java:339`，基类在 `:472` 把结果塞进 `params.setSerializedTable`，对应 thrift `TFileScanRangeParams.serialized_table`，`gensrc/thrift/PlanNodes.thrift:540`）。 + +所以调研报告说「承接的是引擎侧一个既有通用钩子」是对的。真正的多余是：paimon **已经**覆写了扫描级参数填充 `populateScanLevelParams`（`PaimonScanPlanProvider.java:1355`），拿到的正是同一个 `TFileScanRangeParams` 对象（`PluginDrivenScanNode.java:1823` 传的就是节点的 `params` 字段），它完全可以直接 `params.setSerializedTable(...)`，不必绕「写进属性表 → 引擎回调一个通用名方法 → 从属性表里把自己写的键取回来」这一圈。时序上也没问题：`PluginDrivenScanNode.createScanRangeLocations`（:1816-1826）先调 `super`（基类在 :472 设值），再调 `populateScanLevelParams`，后者在后面执行。 + +## 三、为什么这是个问题 + +1. **公共接口的契约不在公共模块**。这是本轮整治反复出现的同一条毛病：接口签名中立（`Map`），真正的语义写在引擎的 `private` 常量和各连接器的字面量里。结果是「新增一个连接器」这件事的成本被抬高到必须先读引擎源码——而读源码这件事本身不产生任何编译期保障。 +2. **字面量对齐靠注释维持**。三个合成键在引擎和 paimon 里各存一份，靠「byte-identical」的注释约束；`hive.text.` 的 12 个后缀在引擎侧是 `PROP_HIVE_TEXT_PREFIX + "column_separator"` 这类拼接、在 hive 侧是 `PROP_PREFIX + "column_separator"` 的另一次拼接。任一侧改一个字母，编译期毫无反应，运行期表现为「该属性静默失效」：比如 `column_separator` 拼错，文本表读出来整行挤在第一列，而不是报错。 +3. **中立接口上挂着源专属命名**。引擎的通用节点里有一个叫 `hive.text.` 的前缀，而它服务的是 TEXT/CSV/JSON 三个格式族、hudi 和 iceberg 走同一条 `getFileAttributes`。这与本项目「通用层不出现源专属符号」的既定纪律直接冲突。 +4. **两个返回面缺一句文档，就是一个静默丢结果的坑**。同时覆写两者不报错、不告警，`Map` 面被无声丢弃。这不是当前的活跃缺陷（现役连接器里只有 es 两个都覆写，且两者指向同一个私有实现 `buildScanNodeProperties`，行为一致），但它是给下一个连接器作者留的陷阱。 +5. **`getSerializedTable(Map)` 是公共接口上一个语义未定义的方法**。名字通用（「返回序列化后的表」），签名不说明什么算「表」、什么格式、给谁用，唯一实现是把自己写的私有键原样取回。新连接器看到这个方法无法判断自己该不该实现。 + +用户能观察到什么？这几条**都不会**表现为当前的错误结果——现役连接器的字符串是对齐的。真实后果是可维护性与新增连接器成本，以及一类「改错一个字母，编译通过、查询静默返回错数据」的高危改动窗口。 + +## 四、用一个最小例子说明 + +假设我要新增一个连接器（叫它 `foo`），表是分区的 Parquet 文件存在 S3 上。我今天要做的事： + +| 我作为连接器作者想做的事 | 今天实际必须怎么做 | 应该怎么做 | +|---|---|---| +| 告诉引擎「用原生 Parquet 读取器，别走 JNI」 | 去翻 `PluginDrivenScanNode.java:1954` 的 `switch`，才知道键叫 `file_format_type`、值必须正好是小写 `"parquet"`，然后在自己代码里写死这两个字面量 | `props.put(ScanNodePropertyKeys.FILE_FORMAT_TYPE, "parquet")`，识别的取值在常量类的 javadoc 里列着 | +| 告诉引擎「`dt` 列是目录分区列，不要从文件里解码」 | 翻到 `:588`，抄 `path_partition_keys`，还得自己发现值是逗号分隔 | `props.put(ScanNodePropertyKeys.PATH_PARTITION_KEYS, String.join(",", keys))` | +| 把 S3 凭证交给 BE | 翻到 `:788`，抄前缀 `location.`；抄错成 `locations.` 则编译通过、查询时 BE 对私有桶报 403 | `props.put(ScanNodePropertyKeys.LOCATION_PREFIX + k, v)` | +| 表是文本格式，要设分隔符 | 翻到 `:799-863` 一行行数出 12 个后缀，还要接受自己的通用连接器代码里出现 `hive.text.` 这个名字 | `props.put(ScanNodePropertyKeys.TEXT_COLUMN_SEPARATOR, "")` | +| 想知道属性表里 `__` 开头的键是什么 | 无处可查（引擎侧 `private`，只有 paimon 复制了一份） | 常量类里明确标注：这三个是引擎注入给 EXPLAIN 用的，永不发往 BE | + +一句话：今天新增连接器需要「读引擎源码 + 抄 5 处字面量」，改完后是「引用 1 个常量类」。 + +## 五、解决方案 + +### 5.1 目标状态 + +**（1）公共模块新增一个键常量类**，路径 `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/scan/ScanNodePropertyKeys.java`，签名草案： + +```java +/** 扫描节点属性表（ConnectorScanPlanProvider#getScanNodeProperties 的返回值）的键契约。 */ +public final class ScanNodePropertyKeys { + + // ---- 连接器 -> 引擎：引擎会读的键 ---- + /** 取值：parquet / orc / text / csv / json / avro / es_http；其余（含缺省）= JNI 读取器。 */ + public static final String FILE_FORMAT_TYPE = "file_format_type"; + /** 逗号分隔的目录分区列名，大小写按 Doris 列名原样。 */ + public static final String PATH_PARTITION_KEYS = "path_partition_keys"; + /** 前缀；剥掉前缀后的键值对整体作为 BE 访问存储的配置。 */ + public static final String LOCATION_PREFIX = "location."; + /** 连接器渲染的远端查询文本，仅用于 EXPLAIN 的 QUERY: 行。 */ + public static final String REMOTE_QUERY = "query"; + + /** 文本类格式（TEXT/CSV/JSON）属性前缀。前缀值沿用历史字面量，与 hive 无关。 */ + public static final String TEXT_PROPERTY_PREFIX = "hive.text."; + public static final String TEXT_SERDE_LIB = TEXT_PROPERTY_PREFIX + "serde_lib"; + public static final String TEXT_SKIP_LINES = TEXT_PROPERTY_PREFIX + "skip_lines"; + // …其余 10 个后缀同上，一个不多一个不少（见 2.2 表格） + + // ---- 引擎 -> 连接器：合成键，永不发往 BE，只供 appendExplainInfo 读 ---- + public static final String SYNTHETIC_NATIVE_READ_SPLITS = "__native_read_splits"; + public static final String SYNTHETIC_TOTAL_READ_SPLITS = "__total_read_splits"; + public static final String SYNTHETIC_EXPLAIN_VERBOSE = "__explain_verbose"; + + private ScanNodePropertyKeys() {} +} +``` + +原则三条：**只收录引擎读的键与引擎注入的合成键**；**所有字面量的值一个字节都不改**；连接器私有键（`paimon.*`、`transactional_hive`、es 那批）留在各自连接器里不动。`TEXT_PROPERTY_PREFIX` 是「符号名中立、字面量保持历史值」的处理——改值需要同时动引擎与 hive 两侧，属于纯改名收益、不在本任务范围（见 5.3）。 + +**（2）包装对象改成具名工厂**，`ScanNodePropertiesResult`：两个构造器降为 `private`，新增 + +```java +public static ScanNodePropertiesResult of(Map properties); // 不做谓词裁剪 +public static ScanNodePropertiesResult withPushdownTracking(Map properties, + Set notPushedConjunctIndices); // 做谓词裁剪 +``` + +3 个构造点全部改成对应工厂。 + +**（3）两个返回面补文档**：在 `getScanNodeProperties` 与 `getScanNodePropertiesResult` 的 javadoc 上各加一段，明确「引擎只调用包装面；包装面的默认实现委派 `Map` 面；**连接器只应覆写其中一个**——若覆写包装面，`Map` 面不再被引擎调用，两者不一致时 `Map` 面的结果会被静默丢弃」。 + +**（4）`getSerializedTable(Map)` 走直接设置的路径**：从 `ConnectorScanPlanProvider` 删掉这个方法；paimon 在 `populateScanLevelParams` 里直接 `params.setSerializedTable(properties.get(PROP_SERIALIZED_TABLE))`（`paimon.serialized_table` 顺便提成 paimon 自己的私有常量，因为它同一个类里出现两次）；引擎侧删掉 `PluginDrivenScanNode.getSerializedTable()` 覆写（:1803-1813）。删完后 `FileQueryScanNode.getSerializedTable()`（:339）与 `:472` 的调用在本仓库再无任何覆写者，一并删除（`fe-core` 纯减，符合只出不进）。 + +### 5.2 改动清单 + +| 文件 | 要做什么 | +|---|---| +| `fe-connector-api/.../scan/ScanNodePropertyKeys.java` | **新增**。按 5.1（1）建类，javadoc 写清每个键的取值约定、读取方是引擎还是连接器 | +| `fe-connector-api/.../scan/ConnectorScanPlanProvider.java` |

`fe-connector-hive/.../HiveScanPlanProvider.java` | 删自有的三个重复常量（:82-84），改引用公共常量类；`PROP_TRANSACTIONAL_HIVE`（:89）**保留**（连接器私有信号，自己的 `populateScanLevelParams` 读） | +|

`getSerializedTable`（:1763-1765）；`populateScanLevelParams`（:1355）里增加 `params.setSerializedTable(...)`；`paimon.serialized_table` 提为私有常量 | +| `fe-connector-jdbc/.../JdbcScanPlanProvider.java` | :185 的 `"query"` 改 `ScanNodePropertyKeys.REMOTE_QUERY` | +| `fe-connector-es/.../EsScanPlanProvider.java` | :184 改常量引用；**删除** `Map` 面覆写（:155-162）——引擎只调包装面（:165 已覆写），这个覆写从引擎侧不可达 | +| `fe-connector-es/.../EsScanPlanProviderTest.java` | :166 与 :341 两处调用 `getScanNodeProperties` 改为 `getScanNodePropertiesResult(...).getProperties()` | +| 相关单测 | paimon 加断言（见第六节）；其余测试若引用了被删的构造器/方法，同步改到工厂方法 | + +### 5.3 明确不要顺手做的事 + +- **不要改任何键的字面量值**，包括不要把 `hive.text.` 改成 `text.`。改值必须引擎与 hive 同步改，收益纯粹是命名，风险是「漏改一处 → 文本表静默读错」。本任务只把符号名中立化。 +- **不要删只写不读的键**（paimon/hudi 的 `table_format_type`、es 的 `_table_name`、hive 的 `hive.text.json_serde_lib`）。它们是独立的死键清理，判活需要单独核对 BE 与 JNI 侧，混进本任务会把「纯结构调整」变成「有行为风险的删除」。 +- **不要碰 `PluginDrivenScanNode:561` 与 :1829-1835 那两处 ES 专属分支**。那是「把通用扫描节点里的源专属分支搬进连接器」那一项任务的正题；本任务只把它读的键换成常量，分支本身原样保留。 +- **不要试图和 `fe-core` 已有的 `FileFormatConstants.PROP_PATH_PARTITION_KEYS`（`FileFormatConstants.java:49`）合并**。那是表函数（TVF）的属性命名空间，字面量相同纯属巧合，且合并会往 `fe-core` 增加连接器相关代码，撞「只出不进」。 +- **不要把 `Map` 面删掉只留包装面**。5 个连接器靠默认委派生效，删掉等于强迫每个连接器去处理谓词追踪参数，是无谓的扩大改动。本任务只补文档、不改机制。 +- **不要为「键必须来自常量类」加 shell/正则构建门禁**。判断一个 `props.put` 的第一个实参是不是常量引用需要理解 Java 语义，本仓库已有明确结论：这类门禁误报比漏报更毒。改动本身由编译期常量引用保障。 + +## 六、怎么验证 + +1. **零残留 grep（存在性检查，可直接跑）**——这是本任务能机器验证的部分： + - `grep -rn '"file_format_type"\|"path_partition_keys"\|"location\."\|"hive\.text\.\|"__native_read_splits"\|"__total_read_splits"\|"__explain_verbose"' --include=*.java fe/fe-core/src/main fe/fe-connector/*/src/main` 期望只在 `ScanNodePropertyKeys.java` 里命中。 + - `grep -rn "getSerializedTable" --include=*.java fe/ | grep -v /target/` 期望 0 命中（`be-java-extensions` 里 BE 侧读 `serialized_table` 的那两处不在 `fe/fe-core` 与 `fe/fe-connector` 下，属另一侧，不受影响）。 +2. **paimon 的序列化表必须仍然到位**（唯一有运行期行为的改动，必须有断言）。在 `PaimonScanPlanProviderTest` 加一条：先 `getScanNodeProperties(...)` 拿到属性表，再 `populateScanLevelParams(new TFileScanRangeParams(), props)`，断言 `params.isSetSerializedTable()` 且值与属性表里 `paimon.serialized_table` 相等。WHY 要写进断言：BE 的 paimon JNI 读取器在 `be/src/format_v2/jni/paimon_jni_reader.cpp:68-71` 对缺失的 `serialized_table` 直接抛错（"missing serialized_table … possibly caused by FE/BE version mismatch"），所以这个字段丢了就是 paimon 全表查询失败。**变异验证**：把新加的 `params.setSerializedTable(...)` 那一行注释掉 → 该断言必须变红。 +3. **两个返回面的委派关系钉一条单测**（放 `fe-connector-api` 的测试源）：写一个只覆写 `Map` 面的匿名 `ConnectorScanPlanProvider`，断言 `getScanNodePropertiesResult(...).getProperties()` 拿到的是那张表、且 `hasConjunctTracking()` 为 `false`；再写一个覆写包装面并用 `withPushdownTracking` 的，断言 `hasConjunctTracking()` 为 `true`。WHY：这两条正是接口新增那段文档的行为承诺，文档不能只是注释。 +4. **es 删掉 `Map` 面覆写后行为不变**：`EsScanPlanProviderTest` 改到包装面后原有断言应全部照旧通过（两个覆写本来指向同一个私有实现 `buildScanNodeProperties`，:173）。这条不需要新增断言，通过即证。 +5. **编译门禁（最强单一信号）**：全反应堆**含测试源**编译，禁用任何跳过测试编译的参数—— + `mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile` + 它同时覆盖「删掉接口方法后所有实现都清理干净」「构造器改 `private` 后调用点全部改到工厂」「`import` 无残留（checkstyle 扫测试源）」三件事。 +6. **跑受影响模块的单测，必须显式关掉 maven build cache**（否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的）： + `mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -Dmaven.build.cache.enabled=false -pl fe-connector/fe-connector-api,fe-connector/fe-connector-paimon,fe-connector/fe-connector-es,fe-connector/fe-connector-hive,fe-connector/fe-connector-hudi,fe-connector/fe-connector-iceberg,fe-connector/fe-connector-jdbc test` + `fe-core` 侧至少跑 `PluginDrivenScanNode*` 那一批（尤其 `PluginDrivenScanNodeVerboseExplainTest`、`PluginDrivenScanNodeExplainStatsTest`，它们覆盖合成键与 EXPLAIN 行）。 +7. **端到端回归**：不需要新增用例，但**必须实跑 paimon 目录的查询回归**（`serialized_table` 是它读数据的必要条件，第 2 条单测只覆盖 FE 侧装配）。hive 文本/CSV/JSON 表的读回归也建议跑一遍，因为 `hive.text.*` 的 12 个后缀经过了一次符号替换。其余连接器只有字面量换常量，属性表内容按字节不变。 + +## 七、风险与回退 + +- **最大风险是「换常量时打错一个后缀」**，尤其 `hive.text.*` 那 12 个。表现不是报错而是该属性静默失效（例如分隔符回退默认值 → 文本表列错位）。防线是第六节第 1 条的 grep（旧字面量必须全部消失）+ 第 7 条的 hive 文本表回归。建议实现时用「先把常量类写全、再逐文件替换、每替换一个文件立刻 grep 该文件是否还有旧字面量」的节奏，不要跨文件批量正则替换。 +- **paimon 的序列化表是硬失败点**：BE 侧对缺失直接抛错，不会静默降级。这既是风险也是好事——一旦漏设，回归立刻红，不会带着错数据上线。 +- **不涉及 thrift 有线格式**：`serialized_table` 字段（`PlanNodes.thrift:540`）本身不动，只是改由谁来 set。 +- **不涉及 Gson 持久化**：属性表只在单次查询规划期内存活，不进元数据镜像。 +- **接口有删除方法（`getSerializedTable`）与构造器降级为 `private`**：插件与公共模块必须同批构建、同批部署；混用老插件包 + 新公共模块会在类加载期报 `NoSuchMethodError`。本仓库连接器与 `fe-core` 一起构建发布，正常流程不会混用；手工替换单个插件 zip 需重新打包全部连接器。 +- **回退**：本任务是「新增一个常量类 + 引用替换 + 一处调用路径改写」，无数据面残留，`git revert` 单个提交即可完整回到原状。建议拆成两个提交（一是常量类 + 引用替换；二是两个返回面文档 + 具名工厂 + `getSerializedTable` 改写），这样第二个提交若有问题可单独回退。 + +## 八、相关背景 + +- 调研报告 `../audit-report.md`： + - 第 10.1 节（b）小节「扫描节点属性表」——本任务的主问题来源：键契约不在公共模块，一半散在引擎私有常量里、一半散在各连接器字面量里，建议在公共模块建一个键常量类； + - 第 10.5 节「方法名与行为不符 / 重载堆叠」最后一条——两个返回面（`Map` 面与包装对象面）同时覆写会静默丢掉一个，且包装对象用「调了哪个构造器」隐式编码一个布尔位； + - 附录 A 第 23 条——`getSerializedTable(Map)`，注意其中的「复核收窄」已确认它承接的是引擎既有通用钩子，本文按修正后的事实叙述； + - 附录 A 第 93 / 94 条与第 139 / 141 条——两个返回面与键契约散落的原始判定。 + - 第 8.3 节「通用引擎代码里残留的数据源分支」——通用扫描节点里的 ES 专属分支，是另一项任务，与本任务在同一文件相邻位置，见 5.3。 +- 设计纪律：见同目录 `07-write-down-the-design-rules.md`（通用层不出现源专属符号、`fe-core` 只出不进）。 +- 同批的接口删除类任务

iceberg 连接器，引擎改为只负责编排每组的 `INSERT-SELECT`、把每组统计原样汇总成一个中立的统计对象交给连接器去渲染成结果行。 + +## 二、背景：现在的代码是怎么写的 + +### 2.1 两种执行方式的分派 + +`ConnectorProcedureOps.getExecutionMode(String)`（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/procedure/ConnectorProcedureOps.java:64-66`）默认返回 `SINGLE_CALL`，连接器可以覆写成 `DISTRIBUTED`。引擎在 `ConnectorExecuteAction` 里按这个声明分派（`fe/fe-core/src/main/java/org/apache/doris/nereids/trees/plans/commands/execute/ConnectorExecuteAction.java:142`、`:158`）： + +- `SINGLE_CALL`：调 `procedureOps.execute(...)`（`:176`），连接器返回一个 `ConnectorProcedureResult`（schema + 行），引擎只是 `wrapResult` 包成结果集（`:213-225`）。**列名列类型完全由连接器决定。** +- `DISTRIBUTED`：构造 `ConnectorRewriteDriver` 并调 `driver.run()`（`:162-166`），驱动器返回 `ConnectorProcedureResult`，同样交给 `wrapResult`。**但这个 `ConnectorProcedureResult` 是引擎自己拼的。** + +全仓只有 iceberg 覆写了执行方式：`IcebergProcedureOps.getExecutionMode`（`fe/fe-connector/fe-connector-iceberg/src/main/java/org/apache/doris/connector/iceberg/IcebergProcedureOps.java:108-113`）在名字等于 `rewrite_data_files` 时返回 `DISTRIBUTED`，其余全是 `SINGLE_CALL`。 + +### 2.2 引擎里硬编码的四列 + +`ConnectorRewriteDriver.java:245-264`： + +```java +private ConnectorProcedureResult buildResult(int rewrittenDataFilesCount, int addedDataFilesCount, + long rewrittenBytesCount, int removedDeleteFilesCount) { + // Four-column schema in the exact legacy order/types (IcebergRewriteDataFilesAction.getResultSchema); + // rewritten_bytes_count is INT for byte-parity with legacy (a latent quirk kept on purpose). + List schema = ImmutableList.of( + new ConnectorColumn("rewritten_data_files_count", ConnectorType.of("INT"), ...), + new ConnectorColumn("added_data_files_count", ConnectorType.of("INT"), ...), + new ConnectorColumn("rewritten_bytes_count", ConnectorType.of("INT"), ...), + new ConnectorColumn("removed_delete_files_count", ConnectorType.of("BIGINT"), ...)); + ... +} +``` + +四个列名、四个列类型、四段列注释文本，全部是 iceberg 这一个过程的历史行为，全部住在 `fe-core` 的一个通用引擎类里。 + +### 2.3 四个统计数字从哪来 + +`ConnectorRewriteDriver.java:177-183`：三个数字由引擎对连接器给出的分组对象求和，一个由事务在提交后回报。 + +```java +int addedDataFilesCount = rewriteTx.getRewriteAddedDataFilesCount(); +int rewrittenDataFilesCount = groups.stream().mapToInt(ConnectorRewriteGroup::getDataFileCount).sum(); +long rewrittenBytesCount = groups.stream().mapToLong(ConnectorRewriteGroup::getTotalSizeBytes).sum(); +int removedDeleteFilesCount = groups.stream().mapToInt(ConnectorRewriteGroup::getDeleteFileCount).sum(); +``` + +其中 `getRewriteAddedDataFilesCount()` 来自窄能力接口 `RewriteCapableTransaction`（`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/handle/RewriteCapableTransaction.java:43-51`），只有提交后才有效。 + +还有一条**空计划早退路径**：`ConnectorRewriteDriver.java:122-125`，当连接器规划出零个分组时，引擎**不开事务**直接返回 `buildResult(0, 0, 0, 0)`。这条路径同样需要列定义，而它发生在任何远程调用之前。 + +### 2.4 连接器一侧本来就有现成的落点 + +`BaseIcebergAction` 已经有 `protected List getResultSchema()`（`fe/fe-connector/fe-connector-iceberg/src/main/java/org/apache/doris/connector/iceberg/action/BaseIcebergAction.java:140-142`，默认空表），构造时捕获一次（`:81`），八个单次调用过程都是通过覆写它来声明自己的结果列的。唯独 `IcebergRewriteDataFilesAction`（`.../action/IcebergRewriteDataFilesAction.java:47`）没有覆写它 —— 因为它的 `executeAction` 是个永不可达的守卫抛异常（`:168-176`），结果列被搬到引擎去了。上面那段引擎注释里的 `IcebergRewriteDataFilesAction.getResultSchema` 指的是**迁移前 fe-core 里的旧同名类**，现在的连接器类里并没有这个方法。 + +### 2.5 中立模块文档里的源专有列名 + +`ConnectorRewriteGroup`（`.../api/procedure/ConnectorRewriteGroup.java`）是中立分组对象，但它的文档用 iceberg 的结果列名来解释每个字段的用途：`:47`（`rewritten_data_files_count`）、`:49`（`rewritten_bytes_count`）、`:51`（`removed_delete_files_count`），三个 getter 注释 `:67`/`:72`/`:77` 又各重复一遍。`RewriteCapableTransaction.java:48` 也提到 `added_data_files_count`。 + +## 三、为什么这是个问题 + +1. **不对称**：同一个 SPI 的两种执行方式，一种把结果列的所有权交给连接器，另一种留在引擎。读代码的人无法从 `ConnectorProcedureOps` 的接口面看出「分布式过程的结果列谁定」。 +2. **新连接器必须改公共模块**：任何连接器想加第二个分布式过程（例如 paimon 的 compact），它的结果列只能通过改 `fe-core` 的 `ConnectorRewriteDriver` 来表达。而 `fe-core` 当前阶段是「只出不进」，往里加第二个数据源的列定义方向就是错的。更糟的是：`buildResult` 只有一套列，两个连接器的两个分布式过程会在这里正面冲突，只能在通用引擎类里按过程名分支。 +3. **一处历史遗留的类型 quirk 归属错了**：`rewritten_bytes_count` 声明成 `INT`，而它承载的值是 `long` 求和出来的字节数（`:179`）；对称地，`removed_delete_files_count` 声明成 `BIGINT`，而它承载的值是 `int`。这两处「类型与直觉不符」是那个 iceberg 过程的历史行为（为与迁移前逐字一致而**刻意保留**），不是引擎的行为规范。放在引擎里，它看起来像是「分布式过程的通用结果契约」，会被下一个连接器照抄。 +4. 用户目前观察不到任何错误：iceberg 是唯一的分布式过程连接器，行为完全正确。**这是一个归属问题，不是正确性缺陷。** 但它是「新增连接器必须动公共模块」清单上的一项。 + +## 四、用一个最小例子说明 + +用户今天执行： + +```sql +ALTER TABLE ice_ctl.db1.t EXECUTE rewrite_data_files("min-input-files" = "2"); +``` + +| 用户写了什么 | 现在实际发生什么 | 应该发生什么 | +|---|---|---| +| 上面这条 SQL | iceberg 连接器规划分组 → 引擎跑 N 个 `INSERT-SELECT` → 引擎**自己**造出 `rewritten_data_files_count / added_data_files_count / rewritten_bytes_count / removed_delete_files_count` 四列并填值 | iceberg 连接器规划分组 → 引擎跑 N 个 `INSERT-SELECT` → 引擎把四个统计数字打成中立统计对象交回连接器 → **连接器**造出同样的四列同样的值 | +| 结果集 | `+---+---+------+---+`（四列，值不变） | **逐字相同**（列名、列顺序、列类型、值全不变） | + +再看「新增一个分布式过程」的成本。假设我要给 paimon 加一个分布式的 `compact` 过程，返回两列 `compacted_file_count` / `compacted_bytes`： + +| 今天必须动的文件 | 改完之后必须动的文件 | +|---|---| +| `fe-connector-paimon`：覆写 `getExecutionMode` + 实现 `planRewrite` | 同左 | +| **`fe-core/ConnectorRewriteDriver.java`**：给 `buildResult` 加一个「如果是 paimon 的 compact 就换另一套列」的分支 | **不用动** | + +## 五、解决方案 + +### 5.1 目标状态 + +引擎只做三件事：编排、把每组统计原样求和、把结果原样透传。列定义与行渲染全在连接器。 + +**新增一个中立的统计对象**（`fe-connector-api`，`org.apache.doris.connector.api.procedure` 包）： + +```java

是另一件事，要单独提、单独评审、单独跑端到端（改类型会改变客户端看到的列元数据）。 +- **不要把 `ConnectorRewriteGroup` 也一起搬进连接器。** 它是引擎编排真正要读的对象（按 `getDataFilePaths()` 给每组扫描定范围，见 `ConnectorRewriteDriver.java:192-198`），必须留在中立模块。本任务只改它的文档措辞。 +- **不要重命名 `ConnectorRewriteDriver` / `planRewrite` / `RewriteCapableTransaction`。** 「rewrite」在这里是合并重写这个操作模型的中立词，不是数据源名。 +- **不要把求和逻辑挪进连接器。** 引擎跑了 N 组、引擎知道跑了几组，汇总是编排的一部分；连接器给的每组数字被原样直和，不做换算、不改单位。 +- **不要顺手给 `getExecutionMode` 加第三种模式，也不要顺手给 paimon/hudi 加分布式过程。** 第四节里的 paimon compact 只是用来说明成本的假想例子。 +- **不要为「结果列不得出现在公共模块」写 shell / 正则门禁。** 判断一个字符串字面量是不是结果列名需要理解 Java 语义，本仓库已有结论：这类门禁只适合存在性与前缀类不变量。靠单测 + 评审。 +- **不要动 `ProcedureExecutionMode` 枚举本身。** 它的两个值和文档都是中立的，只是文档里拿 iceberg 举例，属另一批文档措辞任务。 + +## 六、怎么验证 + +### 6.1 连接器单测（本任务的主断言） + +在 `fe-connector-iceberg` 的 `IcebergProcedureOpsTest` 里新增： + +1. `buildRewriteResultDeclaresFourLegacyColumns`：调 `procOps.buildRewriteResult("rewrite_data_files", new ConnectorRewriteStatistics(3, 4096L, 1, 2))`，断言 + - 列名有序等于 `["rewritten_data_files_count", "added_data_files_count", "rewritten_bytes_count", "removed_delete_files_count"]`； + - 列类型有序等于 `["INT", "INT", "INT", "BIGINT"]`（取 `getType().getTypeName()`，与被删掉的 `ConnectorRewriteDriverTest.java:90-91` 同一断言形状）；测试注释里必须写明第三列的 `INT` 与第四列的 `BIGINT` 是**刻意保留的历史行为**，看到就改是错的； + - 单行等于 `["3", "2", "4096", "1"]`。**四个数字必须互不相同**：这样把「新增数」和「重写数」填反、或把字节数与删除数填反，都会让断言变红（变异验证的着眼点就在这里 —— 用全零或用重复值的断言杀不掉填错顺序）。 +2. `buildRewriteResultRejectsNonDistributedProcedure`：传 `"rollback_to_snapshot"` 应抛 `DorisConnectorException`（照 `planRewriteRejectsNonRewriteProcedure`（`IcebergProcedureOpsTest.java:208-215`）写）。 +3. `buildRewriteResultDoesNotTouchTheCatalog`：用现有 fixture 断言这次调用没有触发任何 `loadTable`（对应 5.1 里「纯本地渲染」那条契约；这条契约支撑引擎的零分组早退路径 —— 那时还没有事务、也没有鉴权作用域）。 + +在 `fe-connector-api` 的 `ConnectorProcedureOpsDefaultsTest` 里新增默认实现抛 `UnsupportedOperationException` 的断言（变异点：默认改成返回空结果 → 误路由变成静默空结果集 → 该断言变红）。 + +### 6.2 引擎单测（职责改成编排） + +改写后的 `ConnectorRewriteDriverTest`： + +- 空计划早退：仍断言 `metadata.beginTransaction` 一次都没被调（保留 `:94-98` 那条变异守卫），并断言驱动器调了 `buildRewriteResult` 且传进去的统计四项全为 0； +- 透传：stub `buildRewriteResult` 返回一个自造的单列结果，断言 `run()` 返回的就是**同一个对象**（`assertSame`），即引擎不再对结果做任何加工。 + +### 6.3 端到端回归 + +**先纠正最初那轮调研里的一条说法**：现有端到端用例并**不**断言列名。已核实 `regression-test/suites/external_table_p0/iceberg/action/test_iceberg_rewrite_data_files.groovy:160-170` 只断言结果非空并按**下标** `[0][0]` / `[0][1]` / `[0][2]` 取值；`test_iceberg_rewrite_data_files_where_conditions.groovy:87-90`、`:117-119`、`:139-145` 同样按下标断言四个值的正负与零。所以： + +- **列名与列类型的逐字一致只能靠 6.1 的连接器单测保证**，端到端兜不住； +- 端到端兜的是**列顺序与取值**：把上述两个用例（外加 `test_iceberg_rewrite_data_files_parallelism.groovy`、`test_iceberg_v3_row_lineage_rewrite_data_files.groovy`）在本地集群跑一遍，下标语义不变即通过。这四个用例已覆盖三条关键路径：正常重写、`WHERE` 收窄重写、`WHERE` 不命中（零分组早退路径，`[0][0..3]` 全 0）。 +- 可选加强（不强制）：在 `test_iceberg_rewrite_data_files.groovy` 里补一句把结果集列名打进日志的断言，让列名从此有端到端护栏。若加，必须与连接器单测的名字一致，不要新造措辞。 + +### 6.4 编译门禁 + +含测试源的全反应堆编译（禁用跳过测试编译的参数）： + +``` +mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml test-compile +``` + +这是最强的单一验收信号 —— 新增的 SPI 默认方法不会破坏任何连接器，但 `fe-core` 两个测试类若忘了补 stub 会在这里就暴露成编译或运行失败。跑具体单测时必须禁用 maven build cache，否则 surefire 会被静默跳过而仍然 `BUILD SUCCESS`。 + +## 七、风险与回退 + +- **主要风险：搬家时把列写错。** 列名拼错、顺序颠倒、类型写反，用户可见的结果集就变了。控制手段是 6.1 里那条「四个互不相同的数字」断言 + 端到端下标断言。 +- **次要风险：漏了空计划早退路径。** 如果只改了 `:182-183` 而漏了 `:122-125`，零分组时会走进老的 `buildResult`（已删）导致编译失败 —— 这个漏项由编译器兜住，不会静默。 +- **第三个风险：把 `buildRewriteResult` 实现成需要加载表。** 那会让「没有分组时不开事务、不做远程调用」这条既有性质退化，鉴权作用域也无处安放。由 6.1 第 3 条断言兜住。 +- **回退**：本任务不涉及持久化格式、不涉及 thrift 有线格式、不涉及 Gson 类型标签，结果集只在 FE 内部经 `CommonResultSet` 直接返回客户端。单个提交 revert 即可完全回到现状。 +- 类加载器方面无新风险：新增的统计对象是纯数据的中立类，编在 `fe-connector-api`（公共模块，编进 `fe-core`），与 `ConnectorRewriteGroup` 走同一条路径。 + +## 八、相关背景 + +- `audit-report.md` 第八主题 8.2 节（「名字中立，但语义只对一个数据源成立」）里关于 `ProcedureExecutionMode.DISTRIBUTED` 的那一条，是本任务的出处。 +- `audit-report.md` 附录 A 第 27 条给出了收窄后的准确表述：问题是**结果 schema 的所有权**错放在 `fe-core`，与 `SINGLE_CALL` 由连接器返回 `ConnectorProcedureResult` 不对称。 +- `audit-report.md` 第十五节整治路线表的第 9 批「中立化」把本任务与 19、20、21 号排在一起；同批任务都改 `fe-connector-api`，但本任务只碰 `procedure` 与 `handle` 两个包，与它们无文件重叠。 +- 对称参照：`RewriteCapableTransaction` 是「窄能力接口 opt-in，而不是往共享契约上加源专有方法」的既有先例（`RewriteCapableTransaction.java:22-30` 的类注释写明了这个理由）；本任务新增的默认抛异常方法沿用 `planRewrite` 的同一范式。 diff --git

+引擎侧的实现只有一个：`fe/fe-core/src/main/java/org/apache/doris/connector/DefaultConnectorContext.java:78`（598 行）。这 11 个方法的实现体占 `:200`～`:507`，加上私有辅助方法一直到 `:566`，以及 5 个字段（`:91` 存储配置供给器、`:96` 原始存储属性供给器、`:103` 文件系统锁、`:104` 缓存的文件系统、`:105` 关闭标记）。文件系统还与生命周期绑定：`close()`（`:371`）关掉缓存的文件系统，由 `PluginDrivenExternalCatalog` 的私有方法 `closeConnectorContextQuietly`（声明在 `:1374`）关掉，调用点在 `:1401`（目录销毁）与 `:158`（重建上下文时关掉旧的）。 + +### 2.3 为什么这次改动被定为高危：两个逐方法转发的钉桩包装类 + +iceberg 与 paimon 各有一个装饰器，把线程上下文类加载器钉到插件加载器上（这是本项目已经踩过四次的类加载器分裂事故的防护）： + +- `fe/fe-connector/fe-connector-iceberg/src/main/java/org/apache/doris/connector/iceberg/TcclPinningConnectorContext.java:74`——`executeAuthenticated` 带钉桩逻辑在 `:98-114`，其后 `:116-210` 全是「纯转发」，其中存储那一段是 `:156-209`； +- `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/TcclPinningConnectorContext.java:63`——钉桩在 `:76-92`，存储转发在 `:134-178`。 + +已核实的转发缺口（也是任务 06 的内容）：iceberg 覆写 18/19，漏 `getFileSystem`；paimon 覆写 17/19，漏 `getFileSystem` 与 `newStorageUriNormalizer`。这两个类正文里明确写了哪些方法**不需要**钉桩（地址归一、BE 连通性探测完全跑在引擎侧，见 iceberg `:173-177` 与 `:203`）。 + +**风险就在这里**：这个接口一动，两个类都要跟着动；而它们承载的是「远程提交时 iceberg-aws 按类名反射加载 S3 客户端」这类只有真跑起来才暴露的机制，单测覆盖不到全部。所以必须做插件包重部署冒烟。 + +### 2.4 测试替身的规模 + +`ConnectorContext` 全仓有 25 个实现：8 个具名 + 17 个匿名。其中生产实现只有 3 个（`DefaultConnectorContext` 与 iceberg / paimon 两个钉桩包装类），另 **22 个是测试替身**。真正覆写了存储方法的替身共 9 处： + +`fe-connector-iceberg/src/test/.../RecordingConnectorContext.java:45`（8 个存储覆写：98 / 104 / 109 / 116 / 127 / 137 / 142 / 183 行）、`fe-connector-hive/src/test/.../RecordingConnectorContext.java:37`（6 个）、`fe-connector-paimon/src/test/.../RecordingConnectorContext.java:39`（3 个），以及 `IcebergConnectorTestConnectionTest`、`HiveConnectorTransactionTest`、`HiveScanBatchModeTest`、`PaimonScanPlanProviderTest`、`HudiBackendDescriptorTest`（2 处匿名）里的内联替身。它们全部标了 `@Override`（已核实）。 + +`fe-core` 的 7 个 `DefaultConnectorContext*Test`（BackendStorageProps / Cleanup / FileSystem / NormalizeUri / Sibling / StorageProps / Vend）全部用**具体类型**声明变量（已逐个核实），所以只要引擎实现类同时实现新接口，这 7 个测试**一行都不用改**。 + +### 2.5 顺带要处理的 `sanitizeJdbcUrl` + +`ConnectorContext:79` 上挂着 `sanitizeJdbcUrl(String)`，javadoc 写的契约是： + +``` +Connectors MUST call this method before using any JDBC URL to establish a database connection. +``` + +已核实的事实： + +- 引擎实现走 `SecurityChecker.getInstance().getSafeJdbcUrl(...)`（`DefaultConnectorContext.java:186-192`），失败抛异常； +- 全仓**唯一**的调用者是 `fe-connector-jdbc`：`JdbcDorisConnector.java:241` 把 `context::sanitizeJdbcUrl` 作为**方法引用**传进 `JdbcConnectorClient.create(...)`，客户端在 `JdbcConnectorClient.java:182` 建连前应用它； +- iceberg 的 JDBC 元存储（`IcebergCatalogFactory.java:601-602`）与 paimon 的 JDBC 目录（`PaimonCatalogFactory.java:196` 把 `uri` 直接塞进 paimon 的 `JdbcCatalogFactory`）都把用户地址原样交给第三方 SDK 建连，从不经过这个钩子。 + +**这不是迁移引入的回退**：上游 master 的老代码同样没有在这两条路上做检查。所以这里要修的是「契约写得比实现宽」，不是补一个安全漏洞。 + +## 三、为什么这是个问题 + +1. **接口没有告诉读者哪些方法与他有关。** 一个新连接器作者（比如接一个纯 JDBC 源）拿到的服务入口有 19 个方法，其中 11 个是他这辈子都用不到的存储与 BE 概念，而接口本身没有任何分组或说明。这条工作线的目标是「照着接口定义就能清晰实现」，19 个方法一锅端是这个目标的直接障碍。 +2. **每加一个存储服务，要改的地方是 4 处而不是 2 处。** 加一个存储方法今天必须动：接口、引擎实现、iceberg 包装类、paimon 包装类。任务 06 把后两处收成一处转发基类之后是 3 处。收成独立服务对象之后是 **2 处**（新接口 + 引擎实现），包装类与转发基类完全不必再动。 +3. **钉桩包装类的表面积越大，漏钉桩的概率越高。** 今天两个包装类逐方法手抄，存储那 11 个占了它们正文的一半以上。把这 11 个搬进一个子对象后，包装类对存储的转发从 11 个方法塌成 1 个取得器——**结构上不可能再漏**，也顺带把任务 06 里那个 `getFileSystem` 缺口在存储侧永久消灭。 +4. **`sanitizeJdbcUrl` 的问题是双重的**：名字把一个通用的出站地址检查钩子写成了 JDBC 专有（中立接口不该出现协议名），契约又用 MUST 承诺了一件没有强制点、且实测只有 1 个连接器遵守的事。读者按字面理解会以为 FE 侧所有外部连接都过了这道检查，实际不是。 + +**注意这不是正确性缺陷**：改完之后没有任何一条查询的结果会变化，收益是接口可读性与「以后改动只需碰 2 处」。这也是它排在最后的原因——**收益不紧急，代价（重部署冒烟）不小**。 + +## 四、用一个最小例子说明 + +假设明天要给引擎加一个存储服务：`getStorageStats(String location)`（返回某个目录的大小，用于统计）。 + +| 时间点 | 我必须改哪些文件 | 漏改的后果 | +|---|---|---| +| 今天 | ① `ConnectorContext`（加带默认实现的方法）② `DefaultConnectorContext`（真实现）③ iceberg `TcclPinningConnectorContext`（加一行转发）④ paimon `TcclPinningConnectorContext`（加一行转发） | 漏了 ③ 或 ④ **不报编译错**：这两个连接器静默拿到接口默认值，且这次调用没有类加载器钉桩 | +| 任务 06 合入后 | ① 接口 ② 引擎实现 ③ `ForwardingConnectorContext`（转发基类，一处） | 漏了 ③ 会被基类单测抓住 | +| **本任务合入后** | ① `ConnectorStorageContext` ② `DefaultConnectorContext` | 包装类与转发基类**不需要动**：它们只转发一个 `getStorageContext()`，存储服务的增删与它们无关 | + +`sanitizeJdbcUrl` 那一半用一段 SQL 就能说清。两条语句里的地址形态完全一样： + +```sql +-- 甲：走 fe-connector-jdbc。地址在建连前经过引擎的出站地址检查，内网地址会被拒。 +CREATE CATALOG c1 PROPERTIES ( + "type" = "jdbc", + "jdbc_url" = "jdbc:mysql://10.0.0.5:3306/db", ...); + +-- 乙：走 fe-connector-paimon 的 jdbc 目录。地址被原样交给

应该怎么写 | +|---|---|---| +| 「使用任何 JDBC 地址建连之前**必须**调用」 | 甲调用了；乙没有（第三方 SDK 内部建连，连接器手里没有建连时机） | 「连接器**自行**建立连接时必须调用；第三方 SDK 内部建连不在本钩子覆盖范围内」 | +| 方法名叫 `sanitizeJdbcUrl` | 引擎实现做的是通用出站地址安全检查，与 JDBC 协议无关 | 改成中立名 `sanitizeOutboundUrl` | + +## 五、解决方案 + +### 5.1 目标状态 + +**第一步（主体）**：在 `fe-connector-spi` 新增 `ConnectorStorageContext`，把上面表格里那 11 个方法**连 javadoc 一起原样搬过去**（一个字不改，只改 `{@link}`

**不要把 `DefaultConnectorContext` 真的拆成两个类。** 那 300 多行搬家会把带锁的文件系统缓存与 `close()` 生命周期一起搬走，风险与本任务的收益（SPI 表面可读性）不成比例；`fe-core` 的内部结构也不是这条工作线的目标。让它同时实现两个接口、返回 `this` 就够了。 +- **不要顺手给存储方法加类加载器钉桩。** 现有两个包装类明确写了这些方法完全跑在引擎侧、不需要钉桩。无差别加钉桩会改变现有行为并带来无谓开销。 +- **不要顺手把 `getHttpSecurityHook` 和改名后的出站地址消毒再收成第三个服务对象。** 只有 2 个方法，收益不足；`getHttpSecurityHook` 的归属（在 `api` 还是 `spi`）是另一条任务的事。 +- **不要顺手给 iceberg / paimon 的 REST / JDBC 目录补上出站地址检查。** 那是一项独立的安全增强（要动第三方 SDK 的建连路径），与上游 master 行为一致、不是本次迁移的回退；混进本任务会让「行为不变」这个验收前提失效。 +- **不要顺手删 `getMetaInvalidator`**（任务 14）**或改动本次范围外的默认值政策**（任务 07）。本任务只搬位置 + 一次改名。 +- **不要为「存储方法是否搬齐」写 shell / 正则门禁。** 本仓库已有结论：这类门禁只适合存在性与前缀类不变量。这里编译器本身就是门禁。 +- ~~**不要变动 `ConnectorPluginManager.java:60` 的 `CURRENT_API_VERSION`。**~~（2026-07-29：该常量与 `ConnectorProvider.apiVersion()`

\ + -Dmaven.build.cache.enabled=false test +``` + +（必须禁用 build cache，否则 surefire 会被静默跳过、`BUILD SUCCESS` 是空的。） + +要断言到的东西： + +1. **新接口的默认值逐字不变**：`ConnectorStorageContextTest` 断言 `NOOP` 的 11 个方法返回值与今天 `ConnectorContext` 的默认值一致——尤其 `getBackendFileType` 按 scheme 推导的四条分支（`hdfs`/`viewfs` → `FILE_HDFS`、`file` 与无 scheme → `FILE_LOCAL`、其余 → `FILE_S3`），这些断言直接从 `ConnectorContextTest:58` 搬过来。 +2. **`getStorageContext()` 不返回 null**：断言未覆写它的匿名上下文返回 `NOOP`，让连接器侧不需要判空。 +3. **转发基类**：任务 06 建立的反射驱动单测继续跑通，并新增一条——空子类的 `getStorageContext()` 返回的是被包装上下文给出的那个实例（不是 `NOOP`）。这条要做**变异验证**：手工删掉基类里的 `getStorageContext()` 转发，确认测试失败并指出方法名，然后恢复。 +4. **两个钉桩包装类的现有断言全部保留不改**：钉桩生效、任务抛异常时恢复调用方加载器、非 Kerberos 走被包装上下文的认证、Kerberos 走插件侧 `doAs`、`createSiblingConnector` 转发给原始上下文。它们是「认证与钉桩语义没被继承结构调整改坏」的证据。 +5. **测试替身迁移不能把断言弱化**：替身改成实现两个接口后，逐个确认原断言仍然**能失败**——挑 3 处代表（hive 的 `getFileSystem`、iceberg 的 `getBackendFileType`、paimon 的 `normalizeStorageUri`），临时把替身的返回值改错，确认对应测试红。这一步是必须的：如果某个替身漏了 `getStorageContext()` 却仍编译通过（它没覆写过存储方法的情况），连接器会拿到 `NOOP`，某些断言可能从「验证归一化结果」退化成「验证原样返回」而依旧变绿。 +6. **改名**：全仓复扫 `sanitizeJdbcUrl` 命中数必须为 0（今天有 7 处：接口、引擎实现、两个包装类各 2 行、jdbc 调用点各 1 行）。 + +### 6.3 插件包重部署冒烟（本任务的核心把关，不可省） + +原因：改的是 parent-first 前缀（`ConnectorPluginManager.java:64-65` 声明 `org.apache.doris.connector.` 与 `org.apache.doris.filesystem.` 走 parent-first）内的接口。FE 与插件包必须**一起重建、一起部署**；混用旧插件 zip 会在运行时报 `AbstractMethodError` / `NoSuchMethodError` 而不是启动期拒绝。 + +步骤： + +1. `mvn -f …/fe/pom.xml package`，取各插件模块 `target/doris-fe-connector-.zip`（由 `src/main/assembly/plugin-zip.xml` 生成）； +2. 清空并重新解包到 `connector_plugin_root`（默认 `${DORIS_HOME}/plugins/connector`），确认目录里没有上一版残留的 jar； +3. 重启 FE，日志里确认 `ConnectorPluginManager initialized … registered types: [...]` 列出全部类型； +4. 至少跑通下面这几条（每条都覆盖一类被改到的存储服务）： + +| 冒烟项 | 覆盖什么 | +|---|---| +| iceberg 目录 `INSERT`（对象存储 warehouse） | 写路径的 BE 文件类型 + 地址归一 + 静态凭证；**同时是 iceberg-aws 按类名反射建 S3 客户端的那条路**，钉桩失效会在这里 `ClassCastException` | +| iceberg `DROP TABLE`（HMS 托管位置） | 空目录清理 | +| iceberg Kerberos 目录的一次读 + 一次写 | 钉桩与「连接器单一认证方」语义，这是唯一活的端到端认证把关点 | +| paimon 目录一次带临时凭证的扫描（REST 目录） | 临时凭证归一 + 批量地址归一器 | +| hive 目录一次分区表扫描 + 一次 `INSERT` | 引擎文件系统（今天唯一真在用它的连接器，14 处调用点里 6 处是它） | +| hudi

+### 6.4 端到端回归 + +本任务不改变任何运行时行为，端到端只作兜底。跑受影响的四个连接器的既有 `external_table_p0` / `external_table_p2` 子集（hive、iceberg、paimon、hudi）与 jdbc 的目录用例（改名影响它的建连路径）。**不需要新增端到端用例。** + +## 七、风险与回退 + +- **最大风险：钉桩失效但单测全绿。** 缓解只有一条——6.3 的重部署冒烟必须真跑，尤其 iceberg 的写入与 Kerberos 两项。单测能证明「转发到位」，不能证明「反射加载落在插件侧」。 +- **风险：测试替身静默弱化断言。** 见 6.2 第 5 条，用挑样变异验证兜住。这是本任务最容易出现的隐性质量损失。 +- **风险：混合部署（新 FE + 旧插件 zip）。** 表现为运行时 `AbstractMethodError`。缓解：冒烟前清空 `connector_plugin_root`；在 commit 信息里写明「插件包必须与 FE 同版本部署」。 +- **风险：与任务 06 的顺序倒置。** 若在 06 之前做，本任务要在两个包装类里各手改 11 处转发，风险显著上升且要重复两遍相同的判断。**06 未合入就不要开工。** +- **风险：与任务 14 撞车。** 14 号删 `getMetaInvalidator`，同样改转发基类。两者不冲突（一个删非存储方法，一个搬存储方法），但**不要合在一个 commit 里**，否则冒烟出问题时无法二分。 +- **回退**：改动全部是结构性的（搬位置 + 改名 + 调用点替换），无数据格式、无持久化、无 thrift 有线格式牵连（新接口保持零 thrift：BE 文件类型仍返回枚举名字符串，broker 地址仍用中立的 `ConnectorBrokerAddress`）。直接 revert 相应 commit 即可，但**必须连同插件包一起回退重部署**。 + +## 八、相关背景 + +- 调研报告 `../audit-report.md`： + - 第 6.1 节的接口规模表中 `ConnectorContext` 那一行——415 行 / 19 个方法 / 9 类能力；以及第 6.3 节建议里「`ConnectorContext` 把存储相关的方法收成一个服务对象，**这一批高危**，必须做插件包重部署冒烟」那一条； + - 第十五节整治路线表的第 11 批「装配上下文拆分」——风险标「高」，原因写明必须做插件包重部署冒烟以验证线程上下文类加载器的钉法； + - 附录 A 第 106 条（大杂烩接口，19 方法 9 类能力）、第 117 条（`sanitizeJdbcUrl` 契约只有一个连接器遵守，判定「成立」）、第 32 条（协议命名的中立性问题，判定「部分成立」，建议改名）、第 125 条（HTTP 安全钩子有同类的契约过宽问题，但明确不是迁移引入的回退）； + - 附录 D.2（两个钉桩包装类的转发缺口机理）——那是任务 06 的来源，也是本任务风险评级的依据。 +- 同一任务空间：**任务 06**（转发基类，本任务的前置）、任务 07（把公共模块的设计规则写下来，包括「新增存储服务加在哪里」这条应写进新接口所在模块的包级说明）、任务 14（删推模型失效接口，同改转发基类，排在本任务前后皆可但不要同 commit）。 +- 项目记忆：`catalog-spi-plugin-tccl-classloader-gotcha`（四个已修的类加载器分裂位置，解释为什么钉桩相关改动必须重部署验证）、`fe-core-source-isolation-iron-rules`（`fe-core` 只出不进，本任务据此选择「引擎实现类同时实现两个接口」而不是搬代码）、`static-gate-only-for-existence-not-language-semantics`（为什么不写静态门禁）、`doris-build-verify-gotchas`（maven 绝对路径 `-f`、后台任务退出码的读法）。 diff --git

`required`（`:29-33`），对外只给四个静态工厂：`stringProperty`（`:46`）、`intProperty`（`:53`）、`booleanProperty`（`:60`）、`requiredStringProperty`（`:67`），另有 getter、`equals`、`hashCode`、`toString`。 +

SET PROPERTIES` 有，`AlterCatalogPropertiesCommand.java:31-36`，但那是改持久化的目录属性，不是按会话覆盖）。 + +**第三，真正缺的那一块（声明式校验与可发现性）今天也已经有连接器侧入口。** 目录属性的键名今天**拼错不报错**：多写一个字母静默失效，用户只会看到「设了没用」。这确实是个缺陷，但补它并不需要描述符——`ConnectorProvider.validateProperties` 就是为此存在的钩子，连接器自己在里面比对键名即可，零公共模块改动。描述符能带来的额外价值只有「统一形状」和「引擎能把可用旋钮列出来给用户看」，而后者要新增一张 fe-core 系统表，与「fe-core 只出不进」的现阶段纪律正面相撞。 + +**用户可见后果**：现状本身没有正确性缺陷。选项一如果做，会有用户可见后果（配置项位置变化）；选项二没有。 + +## 四、用一个最小例子说明 + +场景：**hive 连接器作者想加一个旋钮，控制「列举分区目录时用几个线程」。** + +先看三种作用域今天各要动什么： + +| 我希望这个旋钮怎么设 | 今天必须动的文件 | 涉及模块数 | +|---|---|---| +| 按目录（写在 `CREATE CATALOG` 里） | 只有 `HiveConnectorProperties.java`（加常量）+ 读取处 | **1 个（连接器自己）** | +| 全 FE 一份（写在 `fe.conf` 里） | `fe-common/Config.java` 加字段、`DefaultConnectorContext.buildEnvironment` 加一行转发、连接器加常量与读取 | 3 个 | +| 按会话（`SET`） | `fe-core/SessionVariable` 加字段（`VariableMgr.toMap` 会自动带上）、连接器加常量与读取 | 2 个 | + +也就是说，**「零公共模块改动」这个世界在按目录这一档已经到手了**： + +```sql +-- 今天就能这么用：键名、默认值、解析全在 hive 连接器里，fe-core 完全不知道这个键存在 +CREATE CATALOG hive_a PROPERTIES ("type" = "hms", "hive.ignore_absent_partitions" = "false"); +ALTER CATALOG hive_a SET PROPERTIES ("hive.hms_events_batch_size_per_rpc" = "1000"); +``` + +今天做不到的是这两件事： + +```sql +-- ① 拼错键名：少写一个 s，语句成功、没有任何提示，旋钮静默失效 +CREATE CATALOG hive_b PROPERTIES ("type" = "hms", "hive.ignore_absent_partition" = "false"); + +-- ② 按会话临时覆盖某个目录的连接器旋钮：Doris 没有这个语法，直接报语法错误 +SET SESSION hive_a.ignore_absent_partitions = false; +``` + +两个选项各自能带来什么： + +| | 选项一（接线成声明式属性） | 选项二（删掉三个死接口） | +|---|---|---| +| 上表第一行「按目录」 | 已经零改动，接线后再加一行描述符声明 | 不变，仍然零改动 | +| ① 拼错键名静默失效 | 引擎按描述符统一拒绝未知键 | 仍可修，但走 `validateProperties`，由连接器自己拒 | +| ② 按会话覆盖目录旋钮 | 需要**同时**新增 SQL 语法与 fe-core 解析，描述符只是其中一环 | 不做 | +| 那 7 个 `fe.conf` 键的手工转发 | **不会消失**，除非把键搬到目录属性（兼容变更） | 不变 | + +## 五、解决方案 + +### 5.1 目标状态 + +**选项一：接线成 Trino 那样的声明式属性。** + +保留 `ConnectorPropertyMetadata`，把两个取得器接成真通道。要成立至少需要三件事同时落地： + +1. **描述符成为目录属性的合法键来源**。签名可以不变，但语义要从「表级/会话级」纠正为「目录级」，因为 Doris 的对应物是 `CREATE CATALOG ... PROPERTIES`： + ```java + /** 本连接器接受的目录级属性；引擎据此拒绝未知键并填默认值。 */ + default List> getCatalogPropertyMetadata() { + return Collections.emptyList(); + } + ``` + 注意：校验发生在 `CREATE CATALOG`，那时 `Connector` 实例还没建好，只有 `ConnectorProvider`，所以这个取得器**必须挂在 `ConnectorProvider` 上而不是 `Connector` 上**——这意味着两个现有方法本来的位置就是错的，接线也要搬家。 +2. **未知键的处置要是可开关的**。存量目录里可能已经存了拼错的或第三方工具塞进去的键，直接改成硬拒会让 FE 重启后加载不了既有目录。必须是「先告警、可配置升级为拒绝」的两段式。 +3. **兼容承诺**：那 7 个 `fe.conf` 键一个都不能改名、不能失效。如果同时想把它们变成目录属性，只能是「目录属性优先、缺失时回落到 `fe.conf` 值」的叠加语义，`fe.conf` 键至少保留若干个版本并在文档标记为过时。 + +至于「按会话覆盖某目录的属性」（`SET SESSION 目录.属性`），需要新增 SQL 语法、解析、会话态存储与生命周期，**属于引擎语法层的独立工程，不应塞进这个决策里**；建议明确排除在本次范围之外。 + +**选项二：删掉三个死接口，把入口形状写进设计文档。** + +`ConnectorPropertyMetadata.java` 整文件删除，`Connector.java:234-242` 的两个默认方法删除，`FakeConnectorPluginTest.java:177-178` 两行断言删除（该测试方法其余断言保留）。同时在 7 号任务产出的包级说明里补一段「连接器旋钮该放哪」的规则：按目录的旋钮走 `CREATE CATALOG` 属性 + `ConnectorProvider.validateProperties` 自校验（首选）；必须全 FE 一份的走 `fe.conf` + `buildEnvironment` 转发，并在两侧注释里互指键名；未来若要做声明式属性，正确的入口是 `ConnectorProvider` 上的目录级描述符取得器，而不是 `Connector` 上的表级/会话级取得器。 + +**我的推荐：选项二。** 理由三条。第一，这套接口即使接线也不解决我们真实的两个卡点（值住在 `fe.conf`、没有按会话覆盖语法），它承诺的东西和我们缺的东西不重合；第二，它现在挂错了位置——目录属性校验发生在 `Connector` 存在之前，照现有签名接线一定要重新设计，那已经是「新做一套」而不是「接线」，把死接口留在原地并不能省下这份设计；第三，它现在挡住的那个真缺陷（拼错键静默失效）有一个成本低得多的现成入口 `validateProperties`，可以独立立项，不需要引入引擎侧的属性校验框架。 + +如果你倾向选项一，我的建议是**先只做第 1 件事（目录级描述符 + 未知键告警）**，把 `fe.conf` 键的搬迁和按会话覆盖语法各自单独立项，避免一次改动同时动到用户可见的配置位置和 SQL 语法。 + +### 5.2 改动清单 + +**选项二（推荐）的改动清单：** + +| 序号 |

**不要顺手改那两个活的同名方法**（`PluginDrivenExternalTable.getTableProperties()`、`ConnectorSession.getSessionProperties()`）。前者是 `SHOW CREATE TABLE` 的数据源，后者 8 个连接器在读，与本文毫无关系。 +- **不要顺手清理 `buildEnvironment` 的 7 个转发键**。它们是迁移前既有的 `fe.conf` 名字，删任何一个都是用户可见的兼容破坏；把它们改成目录属性是独立议题，需要单独的兼容设计与文档。 +- **不要顺手把 `max_compute_write_max_block_count` 从会话通道搬到环境通道**——虽然它确实放错了地方（它是 `fe.conf` 字段却走了会话属性通道）。搬家会改变 maxcompute 连接器的读取位置，属于独立的一次修正，且要连带修 maxcompute 侧的读取常量与测试；本文只负责把这件事记录下来。 +- **不要在本任务里做「按会话覆盖目录属性」的 SQL 语法**。那是引擎语法层的独立工程，混进来会让这个决策无法评估。 +- **不要为「描述符必须被声明」写 shell 或正则静态门禁**。判断一个连接器是否声明了描述符属于语言语义范畴，本仓库已有结论：这类门禁误报比漏报更毒。 + +## 六、怎么验证 + +**选项二的验证：** + +1. **全反应堆含测试源编译**（唯一能一次证明「引用全清」的动作，禁止任何跳过测试编译的参数）： + ``` + mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -T 1C test-compile + ``` + `BUILD SUCCESS` 之外任何 symbol not found 当场处理，不许注释掉测试绕过。 +2. **单测**（必须关掉构建缓存，否则测试会被静默跳过而仍报 `BUILD SUCCESS`）： + ``` + mvn -f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -Dmaven.build.cache.enabled=false \ + -pl fe-core test -Dtest=FakeConnectorPluginTest + ``` + 删掉两行断言后，`connectorTopLevelDefaults` 必须仍然覆盖 `getScanPlanProvider()` 为空、`getCapabilities()` 为空、`defaultTestConnection()` 为 false、`testConnection()` 成功这几条——如果删完只剩一两条，就是把测试意图一起删掉了。 +3. **删除彻底性自查**（人工一次，不做成门禁）：全仓 grep `ConnectorPropertyMetadata` 期望零命中；grep `getTableProperties` / `getSessionProperties` 期望**只剩** 2.2 节表里那两个活的方法及其调用点。 +4. **端到端回归：不需要。** 删掉的路径在生产上恒为空列表，无任何运行时行为。 +5. **不需要变异验证。** 没有被保护的行为可供变异。 + +**选项一的验证（若拍这条，正式施工文档里要展开）：** + +- 单测要断言的核心不变量是三条：声明过的键被接受并按 `defaultValue` 填默认；未声明的键在告警模式下**目录仍能创建成功**（这条最重要，它保护的是存量目录能被加载）；开关打开后未声明的键被拒且报错文案里带上键名。 +- 必须做一次变异验证：手工把校验改成恒通过，「未知键被拒」那条用例必须变红；如果不红，说明测试没有真正走到校验。 +- 端到端回归是**硬性要求**（需本地集群）：至少覆盖「用旧 `fe.conf` 键的既有目录重启 FE 后仍能加载并查询」，以及 hive 那三个既有目录属性键的行为不变。这是选项一与选项二在验证成本上的关键差别。 + +## 七、风险与回退 + +**选项二的风险：低。** 删的是恒空列表，运行时零行为。唯一的实质风险是**判断失误**——如果将来确实要做声明式属性，得重新写这个类。但 5.1 节的分析表明现有签名挂错了位置（校验时点没有 `Connector` 实例），将来那次工作无论如何都要重新设计入口，删除并不增加成本。回退就是 `git revert`，无数据、无持久化、无有线格式牵连。 + +**选项一的风险：高**，且集中在两处： + +- **存量目录加载**。如果未知键处置一步到位改成硬拒，任何一个既有目录里存着连接器没声明的键（历史遗留、拼错、第三方工具写入），FE 重启后就加载不了这个目录。这是「重启才炸」的类型，测试环境不一定复现。所以两段式（默认告警、开关升级为拒绝）不是可选项而是必需项。 +- **配置项位置的兼容承诺**。7 个 `fe.conf` 键一旦对外宣布「已改为目录属性」，就不能反悔。回退代价远高于代码回退——文档、用户脚本、运维手册都会跟着走。 + +无论选哪条，本文档的决定都要回写到 `plan-doc/connector-public-interface-cleanup/HANDOFF.md` 的待拍板段落与 `README.md` 的任务表，并同步调整 11 号任务的改动清单第 1 项。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` + - 第 4.5 节「一个尚未排期、需要先拍板的落点：连接器自声明属性」——本文的出处；注意其中「所有数据源专属旋钮只能落到全局配置与会话变量」的判断经本文核实**过宽**，按目录的通道已经存在。 + - 第 7.2 节「可以直接删」表格第一行——把这三个接口列入直接删除项，与本文选项二一致。 + - 附录 A 第 43 / 47 / 55 / 91 条——同一处发现的四次独立命中（属性描述符体系零实现零消费），其中 55 与 91 已经注意到了 2.2 节说的撞名问题。 +- `plan-doc/connector-public-interface-cleanup/tasks/11-delete-dead-surface-batch-one.md` 的改动清单第 1 项——**与本文选项二是同一件事，只能做一次**。 +- `plan-doc/connector-public-interface-cleanup/tasks/07-write-down-the-design-rules.md`——选项二要补的那段「连接器旋钮该放哪」的规则应落在这份包级说明里。 +- `plan-doc/connector-public-interface-cleanup/tasks/06-fix-engine-context-forwarding-gap.md`——同样在讨论 `ConnectorContext` 这条通道（那份讲的是转发漏抄，本文讲的是转发内容），两者不冲突。 diff --git

降级成整表失效）、统计失效是空操作（`:71-77`）。既然一整套要删（另有一份《删除推模型的缓存失效接口》任务负责删代码），名字冲突自然消失，不需要给活着的那组（`Connector.invalidate*`）改名去动 8 个连接器。 +2. **分区空值哨兵（第 186 行、第 650 行的建议：`HIVE_DEFAULT_PARTITION` 下沉到 hive 连接器）**——实测不能下沉，三条硬约束：引擎自己的分区路径解析在用它（`fe-core/.../datasource/scan/FilePartitionUtils.java:143`）；非 hive 连接器 paimon 主动把空分区归一成这个串（`PaimonConnectorMetadata.java:1263`）；引擎侧已经存在第二份同串定义（`fe-core/.../datasource/TablePartitionValues.java:47`）。下沉只会变成三份，还会让 fe-core 反过来依赖 hive 插件。 +3. **压缩类型调整方法（第 164 行把它列进「源专有语义混入」，第 650 行要求「文档去 Hadoop 化」）**——实测 `adjustFileCompressType`（`ConnectorScanPlanProvider.java:125`）的方法名与默认值本来就是中立的（默认恒等），javadoc 里提 Hadoop / LZ4 的那段（`:117-121`）**恰恰是在解释为什么必须有这个钩子**，末句原文就是 `This keeps that hadoop-specific fact inside the connector; the generic node stays connector-agnostic.`——它是「通用节点不得出现数据源专有代码」这条规则的正面案例，不是违规。把这段说明删掉，只会让下一个维护者不知道这个钩子干什么、进而把 LZ4 重映射写回通用节点。 + +## 三、为什么这是个问题 + +这份文档不是随笔，它是会被人当施工依据用的：它的第五节就是一份编号 1–17 的行动清单。清单里的条目一旦照着做，后果是实打实的： + +- **会做重复劳动**：按「8 个连接器没有一个调用契约校验器」去给 8 个模块补契约测试，其中 4 个是已经存在的；而真正缺的那一个（hive）在原文里根本没被点出来，最可能被漏掉。 +- **会写出编译不过的删除补丁**：按「7 个连接器」去删分片类型，漏掉 trino，`TrinoScanRange` 立刻编译失败。这类错误会被编译挡住，代价只是返工，但它会让人怀疑整份清单的可信度。 +- **会改坏正在跑的功能**：把 `HIVE_DEFAULT_PARTITION` 下沉到 hive 连接器，引擎自己的分区路径解析和 paimon 的空分区归一化都会断，而且方向上让 fe-core 依赖插件——违反本阶段「fe-core 只出不进」的纪律。这一条是清单里唯一有真实破坏力的。 +- **会删掉有价值的解释**：把压缩类型调整方法的 javadoc「去 Hadoop 化」，等于删掉唯一说明这个钩子为何存在的段落，下一个维护者很可能把 LZ4 重映射写回通用扫描节点——那才是真正的中立性违规。 +- **会白花一次跨 8 个连接器的改名**：按「给同名反向的失效接口改名」去动活着的那一组，触及 8 个连接器加 fe-core；而正确做法是把死的那一整套删掉，名字冲突自然消失。 + +至于规模数字，本身不影响正确性，但它们出现在「现状概览」表里，是别人引用最多的部分；错的数字会一路传下去。 + +修文档而不是留个勘误在别处，是因为读那份文档的人不会同时读勘误。 + +## 四、用一个最小例子说明 + +| 那份文档怎么说 | 一个人照着动手会发生什么 | 实测事实 | +|---|---|---| +| 8 个连接器没有一个调用契约校验器，这 4 条规则今天完全没被验证 | 在 8 个连接器模块各加一个契约测试——其中 4 个是重复建设 | 4 个连接器已经在调，只差 hive 一个（它是唯一声明分区哈希写的连接器） | +| 全部 7 个连接器实现了 `getRangeType()` |

+改完之后，`plan-doc/connector-api-spi-design-review-2026-07-25.md`： + +1. 头部（现在第 6 行「本文只做分析和建议，不改动任何代码。」之后）多出一小段，大意是：同一天另有一轮独立重做的审查，结论与本任务空间的报告 `plan-doc/connector-public-interface-cleanup/audit-report.md` 及其 `tasks/` 目录并存；两份都保留，因为两轮独立结论的一致部分本身就是可信度最强的证据，分歧部分才是需要人拍板的地方；本文中经交叉核对修正过的地方均以「（交叉核对修正）」标注。 +2. 5 处事实错误就地改成实测事实，涉及数字的直接换数字，涉及结论推导的把作废的推导一起删掉。 +3. 3 条结论按 2.5 节反转，行动清单（第 625 行起那一节）里对应的条目同步改掉，避免正文改了、清单还写着旧结论。 + +**不新增小节、不改写它的分析框架、不把本轮报告的内容搬进去。** + +### 5.2 改动清单 + +| 那份文档的位置 | 现在写的 | 改成 |

建议给其中一组失效接口改名 | 改成：删掉推模型那一整套（零连接器调用、引擎侧履约不了分区粒度契约），名字冲突随之消失；并指向本任务空间里《删除推模型的缓存失效接口》那份任务文档 | +| 第 529–531 行 | 8 个真实连接器没有一个调用过 | 4 个连接器在调（列出 4 个文件与行号）；真实缺口＝唯一声明分区哈希写的 hive 没有调用点 | +| 第 532 行与第 536 行 |

**不要顺手校对它其余的数字与结论。** 本任务只动经实测的这 8 处；未经核实的地方保持原样，比改成一个没人验过的新数字更安全。 +- **不要顺手改 Java。** 删除分片类型枚举族、删除推模型失效接口、给 hive 补契约测试，各自是本任务空间里独立的代码任务（见第八节的文件名）。本任务改完之后 `git diff --stat` 应该只有一个 markdown 文件。 +- **不要把 `adjustFileCompressType` 从第 551 行的 thrift 类型清单里删掉。** 它的入参是 `TFileCompressType`，这一条（公共接口签名里出现 thrift 类型）依然成立，与「不算中立性违规」的那条结论并不矛盾——一处是语义中立性，一处是类型依赖。 +- **不要把本轮报告附录 C.3 那六条补记搬进那份文档。** 附录 C.3 是「那份文档独有、经核实成立、应当并入的六条」——分片格式默认值 `"jni"`、建库布尔位与建库方法必须同进同退、带快照与不带快照的重载堆叠、thrift 返回类型写成内联全限定名、「提供者无状态」与「释放跨调用读事务」自相矛盾、按名字寻址导致异构网关拿不到表注释。那些是本轮的内容，各有归属任务。 + +## 六、怎么验证 + +本任务不改 Java，所以**全反应堆 test-compile 不是本任务的验收信号**（如果有 Java 变更出现，说明范围越界了，应当退回）。验收靠两件事：改动后逐条重跑证据命令，和对原始错误字符串做「已消失」断言。 + +改完后在仓库根依次执行，逐条核对输出与文档里写的一致： + +```bash +# 契约校验器的真实调用点：应有 4 个连接器测试文件 +grep -rn "ConnectorContractValidator.validate"

+不需要单元测试、不需要变异验证、不需要端到端回归——本任务不产生任何运行时行为。 + +## 七、风险与回退 + +风险低：单文件文档改动。 + +> **⚠ 这句回退方式在动手时是错的（落地时已修正）**：那份文档当时**从未被 git 跟踪过**（任何分支、任何提交里都不存在，也没有被 ignore，只是从来没人 `git add` 过）。所以 `git checkout -- <该文件>` 只会报 `pathspec did not match`，也没有任何 commit 可以 revert。落地时先把它**原样入库**成一个独立提交，才使"可 diff、可回退"成立。 + +唯一真实风险是**改过头**：一边改一边顺手把整份文档拉平成本轮报告的口径，那样就丢掉了「两轮独立结论」这个可信度证据，也丢掉了那份文档独有的、经核实成立的若干条（接口规模的精确计数、写特性按表缺口、thrift 出现位置清单）。缓解办法就是 5.3 的第一、二条：只动清单里那 8 处 + 头部，改动处统一加标记，提交前用 `git diff` 逐行过一遍。 + +## 八、相关背景 + +- `plan-doc/connector-public-interface-cleanup/audit-report.md` 附录 C：本任务的全部素材来源。C.2 是这 5 处事实错误与 3 处结论改动的原始记录，C.5 是「两份都保留」的处置建议。 +- 同一报告附录 C.1：两轮互有胜负的地方，动手前值得读一遍，避免把那份文档比本轮更准的部分也一起改掉。 +- 同一报告附录 C.3：那份文档独有、经核实成立的六条，它们属于本轮报告与其它任务的范围，**不要**写回那份文档。 +- 本任务空间 `tasks/13-delete-scan-range-type-enum.md`：分片类型枚举族的实际删除任务，本任务只是把「7 个」改成「8 个」，真正删代码在那里。 +- 本任务空间 `tasks/14-delete-push-model-cache-invalidation.md`：推模型失效接口的实际删除任务，对应 2.5 第 1 条反转后的结论。 +- 本任务空间 `tasks/08-fix-stale-interface-docs.md`：那份文档里「接口文档与实现互相矛盾」那一批的落地任务；其中关于契约校验器注释的那一条需要按本任务修正后的口径来做，不要再按「注释描述了不存在的机制」处理。 + +--- + +## 九、落地记录（2026-07-26，三个提交） + +**提交**：`[doc](catalog) check in the same-day SPI design review, unmodified`（原样入库）、`[doc](catalog) date-stamp the SPI design review against the tree it now faces`（标注修订）、`[doc](catalog) correct three stale code comments the review cross-check turned up`（代码注释）。 + +### 9.1 动手前的重侦察推翻了本文的前提 + +本文写于 44 个提交之前。开工前用 16 个并行核查单元回到 HEAD 逐条复核，结论是**不能照本文直接施工**： + +1. **目标文档从未被 git 跟踪**（见第七节的修正框）。本文第六节那批「原始错误字符串必须消失」的 grep 断言，前提也随处置方案改变而失效——见 9.3。 +2. **本文列的 8 条勘误自己也过期了**：4 条仍然成立（其中 1 条要收窄、1 条要改时态）、3 条已被代码变更取代、**1 条彻底失去对象**。 + - 第 2.2 条（把「7 个连接器」改成「8 个」）已 **moot**：分片类型枚举族整族已被删除。照本文改，等于在那份文档里新写一条指向已删符号的待办。 + - 第 2.4 条的数字**只剩 3 个还准**：`ConnectorSession` 15、`ConnectorPartitionInfo` 6、`ConnectorType` 7 未变；模块规模已是 101 文件 / 10978 行，`Connector` 已从 34 掉到 21。 + - 第 2.5 第 2 条的三条硬约束**第 3 条已假**：引擎侧那份重复定义已经删掉，全 FE 树现在只有一处定义；符号也已改名。本文漏列了引擎的第三个消费者（渲染 `partition_values()` 表函数那一格）。 + - 第 2.5 第 1 条仍然成立，但要改时态：本文写的是「另有任务负责删代码」（将来时），实际那一整套已经删完。 +3. **本文只覆盖了 8 处，而实际失效的远不止**：去重后约 **26 个独立论断**失效，散落在 40 余处文字。其中至少 5 处照着做会重复劳动、扑空、或改坏正在跑的功能。 + +### 9.2 处置方案改为「加状态戳 + 重编两块」（用户拍板） + +本文第五节原定的「就地改掉这 8 处、其余一字不动」在复核后已不成立（会留下 26 处误导）。实际执行的是：**分析正文一律保留**（它是评审快照，价值在"当时看到了什么"），只加三类标注——状态戳 36 处、交叉核对修正 15 处、就地重算 3 处——并把「现状概览」两张表与文末 17 条行动清单按 HEAD 重编。理由是"当前现状"的权威位置**已经搬进代码注释**（包级说明的规则一/规则三、各域接口的最少实现集、契约校验器的实际覆盖段落），markdown 不该再当第二真相源。 + +### 9.3 本文第六节的验收口径需要按此调整 + +- 「原始错误字符串必须全部消失」这批断言里，**只有 2 条仍适用**（`约 9800 行`、`8 个构造函数`——这两处是数字，已就地换掉）。另外 3 条（`8 个真实连接器没有任何一个`、`全部 7 个连接器`、`空 spec = 另一回事`）按新方案**刻意保留原句**，紧随其后跟一个交叉核对修正块；用原 grep 去断言"已消失"会误判。 +- 本文 5.2 那张改动清单里，第 164 / 183–186 / 211–212 / 417 / 475 / 529–531 / 532 / 536 / 589–591 / 650 各行都改为"保留原句 + 加修正块"，不是就地替换。 + +### 9.4 复核额外查出、本文没有的三条事实错误 + +前两条在本任务空间的交接文档里已挂号，第三条是本次新发现： + +1. `ConnectorRewriteDriver` 里引用了树中已不存在的旧类名。**交接文档说"两个类名都不存在"只对一半**——另一个类是活的，只是搬进了 iceberg 连接器；同时还有一处交接文档没发现的同类引用（在 iceberg 连接器的重写规划器里，两个旧类名都已改名）。 +2. `ConnectorWritePlanProviderDefaultsTest` 的类注释说默认值"必须是空列表"，而接口默认返回 `null`、**该测试自己的断言也是断言 `null`**——注释与它守护的断言互相打脸。 +3. **（新发现）** `ConnectorRewriteStatistics` 的类注释说"前三个数字是求和、第四个来自事务"，实际求和的是第一、三、四个，来自事务的是**第二个**（引擎侧构造点的注释是对的，值对象的注释说反了）。照注释理解会把字段对错位。 + +三条都已修，是本轮第三个提交。**另有一条经复核确认仍然成立、但至今没有任何任务认领**：统计接口「列举文件大小」的异常契约，接口 javadoc 要求吞异常返回空集合，而唯一实现与新写进包级说明的「响亮失败」规则都说必须抛——本轮用户明确只修注释、不动这条契约，已登记待排期。 diff --git a/plan-doc/connectors/_template.md b/plan-doc/connectors/_template.md new file mode 100644 index

解码）；maxcompute 每查询一次 ODPS `getPartitions()`；hive 每查询把 HMS 名单解析成 `ConnectorPartitionInfo`（原始名单已被 `CachingHmsClient` 缓存，此处是解析 CPU）。 +2. **派生视图重建成本**：fe-core 每查询把分区名单构建成 `nameToPartitionItem`（`PartitionItem`），并在 `PruneFileScanPartition` 里用 `SortedPartitionRanges.build()` 重建二分查找结构（O(n) 建 range + O(n log n) 排序）。legacy 里这份 `SortedPartitionRanges` 是缓存复用的（`HiveExternalMetaCache.HivePartitionValues` 构造函数里建一次、跨查询复用），翻闸后变成每查询重建。 + +对**大量分区**表，这两块都显著。本设计恢复这两层缓存，同时满足 SPI 隔离、且不复发 #65659 的 TOCTOU。 + +## 2. 目标 / 非目标 + +**目标** +-

PARTITIONS / partitions-TVF 的"取新"仍由既有 per-call fresh 路径（`listPartitionNamesFresh` 等）承担，与本缓存正交、绕过缓存 A。 + +## 3. 现状梳理（设计所依赖的事实） + +- **每语句冻结层已存在（相当于 Trino 的 per-transaction memoizer）**：hive/iceberg/paimon 都是 `PluginDrivenMvccExternalTable`；分区视图在 `materializeLatest()`（`PluginDrivenMvccExternalTable.java:127`）**每语句只物化一次**，冻结进 `PluginDrivenMvccSnapshot`（存于 `StatementContext.snapshots`，per-statement 实例字段）。`PruneFileScanPartition` 读的是冻结的 `SelectedPartitions`，绝不回连缓存——这是 #65659 TOCTOU 不复发的结构性原因。 +- **裁剪路径 `listPartitions` 永远不带 filter**：全部 4 个调用点（`PluginDrivenExternalTable.java:831/:887`、`PluginDrivenMvccExternalTable.java:271`、`ShowPartitionsCommand.java:300`）传 `Optional.empty()`。 +- **二分裁剪机制在分支中完好且已在用**：`PartitionPruner.pruneWithResult`（`PartitionPruner.java:163`）在 `sortedPartitionRanges.isPresent()` 时走 `binarySearchFiltering`（`:204-209, :255`），由 session 变量 `enableBinarySearchFilteringPartitions` 控制；#65659 合并后 `PruneFileScanPartition` 每查询用 `.or(() -> SortedPartitionRanges.build(nameToPartitionItem))`（`PruneFileScanPartition.java:101-102`）现建 ranges 后照常二分——功能与 legacy 一致，唯缺缓存复用。 +- **fe-core 已有引擎无关、按版本 keyed 的 ranges 缓存**：`NereidsSortedPartitionsCacheManager`（`common/cache/NereidsSortedPartitionsCacheManager.java`），key=`TableIdentifier(catalog,db,table)`，`PartitionCacheContext(tableId, partitionMetaVersion, sortedPartitionRanges)`，`get()`（`:74`）用 `getPartitionMetaVersion(scan)` 校验版本、变更即重建（`:98-102`），`loadCache()`（`:117`）带"插入过频跳过排序"启发式（`:127-131`），软值 + FE 配置 TTL。**OLAP 表已通过 `PruneOlapScanPartition.java:161-168` 在用**。其接口 `SupportBinarySearchFilteringPartitions`（`catalog/SupportBinarySearchFilteringPartitions.java`）javadoc 明言"you can save the partition's meta snapshot id in the CatalogRelation and get the partitions by the snapshot id"——为外表 MVCC 快照场景预留。 +- **外表当前完全绕过它**：`ExternalTable.getSortedPartitionRanges(scan)`（`ExternalTable.java:527`）返回 `Optional.empty()` 空桩，且 #65659 合并后**已无任何调用者**（死代码）。 +- **已有连接器侧缓存基建**：`fe-connector-cache` 的 `CacheSpec`（属性模型 `meta.cache...(enable|ttl-second|capacity)`）+ `MetaCacheEntry`（Caffeine，contextual-only + manual-miss，generation 计数失效）。iceberg 已有 `IcebergPartitionCache`（key=`(TableIdentifier, snapshotId)` → `List` **原始行**）、`IcebergLatestSnapshotCache`（`(snapshotId, schemaId)` 快照钉子）；hive 有 `CachingHmsClient`（缓存 `listPartitionNames`/`getPartitions` 原始 HMS 元数据）。**但派生视图（`ConnectorMvccPartitionView` / `List`）每次重算**。 +- **连接器失效缝**：`Connector.invalidateTable/invalidateDb/invalidateAll/invalidatePartition`（`fe-connector-api/.../Connector.java:312/316/324/336`，默认 no-op，引擎 override）。REFRESH

MVCC**：`metaVersion = 连接器维护的单调 generation`（连接器内 `ConcurrentHashMap`，`invalidateTable/invalidatePartition` 时 bump、缓存 A reload 时 bump）。廉价 in-memory、精确，且**让缓存 A 与缓存 B 版本联动**（B 的 ranges 绝不比 A 的视图更旧）。 + +`getPartitionMetaVersion(scan)` 从 scan 的 pinned 快照读出该 `metaVersion`（scan 携带 `tableSnapshot`/`scanParams` → `StatementContext.getSnapshot` → pinned `PluginDrivenMvccSnapshot` → `ConnectorMvccSnapshot.metaVersion`）。 + +## 8. 正确性论证（两层皆不复发 #65659 TOCTOU） + +- **缓存 A**：只在 `materializeLatest()` 那一次被读，读出即冻结进 `PluginDrivenMvccSnapshot`；`PruneFileScanPartition` 只读冻结副本，绝不回连缓存 A。同一 key 并发命中返回同一不可变 value。跨查询：MVCC 令牌保证永不把 S+1 当 S；hive 为 bounded-staleness（TTL + 失效钩子，= `use_meta_cache` 契约）。 +- **缓存 B**：`getPartitionMetaVersion(scan)` = pinned 快照/generation，`getOriginPartitions(scan)` 返回同一 pinned 快照的冻结 `nameToPartitionItem`——ranges 与 `nameToPartitionItem` **同源**；版本不符即重建。故 `prunedPartitions ⊆ nameToPartitionItem.keySet()` 恒成立，`PruneFileScanPartition` 的 `Preconditions.checkState(item != null, ...)`（#65659）永不触发。 +- **查询内一致**由既有冻结层保证（物化一次）；**跨查询**由版本令牌（MVCC）/ TTL+失效（hive）保证 bounded staleness。二者组合等价于 Trino 的"共享 TTL 层 + per-transaction memoizer"。 + +## 9. 隔离与配置 + +- **SPI 隔离**：缓存 A 完全在 SPI 线以下（连接器 final 字段，缓存 SPI 类型），fe-core 一行不改。缓存 B 在 fe-core，但 key=`(表)+不透明 SPI 令牌`、`getOriginPartitions` 只消费 SPI 输出、失效走连接器钩子——不碰引擎内部，与 OLAP 同构。 +- **session=user**：缓存 A 沿用"置 null 禁用"。缓存 B 只存 `(表,快照)` 维度 ranges、**不含任何凭证**，与 OLAP 同样跨用户共享安全（同 snapshotId ⇒ 同分区集），不禁用。 +- **配置开关**：缓存 A `meta.cache..partition_view.(enable|ttl-second|capacity)`（默认 ON/86400s），`enable=false`/`ttl=0` 一键关（对应 Trino `cache-partitions=false` 逃生阀）；缓存 B 复用现有 session 变量 `enableBinarySearchFilteringPartitions` + `cacheSortedPartitionIntervalSecond` + FE 配置（`NereidsSortedPartitionsCacheManager` 现有的 `sortedPartitionTableManageNum`/`expireSortedPartitionTableInFeSecond`）。 + +## 10. 失效汇总（复用现成管线，零新增管线） + +| 触发 |

换成对应族名即可。 + +### 12.1 第一步：判定 major 还是 minor + +``` +改动是否让 SPI 表面发生任何变化？ +（新增/删除接口类型、新增/删除方法、改参数或返回类型） + │ + ├─ 是 ──► major + 1，minor 归零 1.3 → 2.0 + │ + └─ 否 ──► 接口表面不变，只是实现变了？ + │ + ├─ 是（行为/性能/内部重构）──► minor + 1 1.3 → 1.4 + │ + └─ 只是 bugfix，行为不变 ──► patch + 1（可选）1.3 → 1.3.1 +``` + +判据只有一条：**SPI 表面动没动**。拿不准时看表面基线测试红不红——它红了就是 major。 + +### 12.2 Doris 侧：一次 major 变更的完整步骤 + +1. 改 SPI 代码，例如给 `ConnectorProvider` 加一个方法。 +2. 跑该模块测试 → 表面基线测试变红，失败信息提示"这是 major 变更"。 +3. 刷新基线文件（把失败信息里的 actual 集合抄进 `src/test/resources` 下对应的 `.txt`）。 +4. **bump 一个数字**：`fe/fe-connector/pom.xml` 的 + `` 由 `1.3` 改成 `2.0`。 +5. 重新构建。这一步之后**自动发生**两件事，无需人工干预： + - `fe-connector-spi` 的 filtered resource 变成 `2.0` → 内核期望值更新； + - 8 个连接器 jar 的 MANIFEST 变成 `2.0` → 插件声明值更新（它们继承父 pom）。 +6. 全反应堆验证。**用 `package` 不要用 `test-compile`**（见 §14.10：冷缓存下 `test-compile` + 拿不到 shade 产物）： + ```bash + mvn -o -f fe/pom.xml -Dmaven.build.cache.enabled=false \ + -Dcheckstyle.skip=true -Dexec.skip=true -DskipTests package + ``` + 禁缓存这一条对**本流程尤其关键**：bump 版本号时构建缓存正是最容易骗过你的东西（§14.8c）。 + +**树内 8 个连接器的 pom 一个都不用改。** 这是 property 继承的直接结果——版本号只在父 pom +里出现一次。 + +唯一需要改连接器代码的情况：新增的 SPI 方法是**抽象**的（无 default）。那是编译错误驱动的 +代码改动，与版本机制无关。 + +### 12.3 Doris 侧：minor / patch 变更 + +只改 §12.1 判出的那一位数字，其余同 §12.2 的第 5、6 步。表面基线不会红（表面没变）， +所以**没有自动信号提醒你 bump minor**——minor 不参与校验，漏 bump 只影响 +`information_schema.extensions` 的展示，不影响正确性。 + +### 12.4 第三方插件：要做什么 + +**查出内核期望哪个版本**，两个途径： + +```bash +# 途径一：读 SPI jar 里的声明 +unzip -p fe-connector-spi-*.jar META-INF/doris/connector-plugin-api-version.properties + +# 途径二：被拒时 FE 日志的 ERROR 行会同时打印声明值与内核期望值 +``` + +**在插件 pom 里声明**（首次接入时加，之后每次 Doris major 变更时更新这一个数字）： + +```xml + + + 1.0 + + + + + + org.apache.maven.plugins + maven-jar-plugin + + + + ${doris.connector.plugin.api.version} + + + + + + +``` + +**打包时必须排除**内核提供的契约 artifact（否则插件 zip 里会带重复副本）： +`fe-connector-api`、`fe-connector-spi`、`fe-extension-spi`、`fe-filesystem-api`。 +参照树内**任一**连接器的 `src/main/assembly/plugin-zip.xml`——8 个现在一致 +（es / trino 原本漏了 `fe-filesystem-api`，已在本次修复，见 §1 勘误）。 + +**Doris 升 major 之后的适配顺序**： + +1. 依赖升到新版 `fe-connector-spi` / `fe-connector-api`； +2. 修编译错误（新 major 可能删了或改了你用的接口）； +3. 把 pom 里那个 property 改成新值； +4. 重新打包、替换 plugin 目录、重启 FE。 + +**写错版本号会怎样**：写小了（声明 1.0、实际按 2.0 编译）→ 被拒，安全失败。写大了 +（声明 2.0、实际按 1.0 编译）→ 放行，但运行期可能报 `NoSuchMethodError`。后者属于主动 +谎报，本机制不防；§5.2 的 fail-closed 只保证"什么都不写"不能通过。 + +### 12.5 部署与运维 + +- **内核与插件必须同批升级**。major 严格相等，没有过渡期、没有兼容窗口。 +- 树内插件天然同步：`build.sh` 把它们装进 `output/fe/plugins//`，与 FE 同批产出。 +- 升级前的检查清单：所有**第三方**插件是否已有对应新 major 的版本。 +- 升级后的验证： + - 查 FE 日志有无 `STAGE_API_VERSION` 的拒绝记录； + - 查 `information_schema.extensions`，**被拒的插件不会出现在这张表里**——某个插件消失 + 就是它被拒了。 + +### 12.6 诊断：插件没加载出来 + +| 症状 | 查什么 | +| --- | --- | +| `CREATE CATALOG` 报未知类型 | FE 日志搜该插件目录名 + `STAGE_API_VERSION` | +| `extensions` 表里少了某插件 | 同上；ERROR 行会打印声明值 vs 内核期望值 | +| 认证类型报 "No authentication plugin factory found" | 该消息已带版本拒绝原因（§5.3）；否则是真的没装 | +| 日志说"缺少版本声明" | 插件 jar 的 MANIFEST 没有对应属性，按 §12.4 补 | + +--- + +## 13. 未决 / 后续 + +1. ~~§8 的 `Implementation-Version` 顺带项，待 owner 明示做或不做。~~ **已关闭**：前提被实证 + 推翻（ASF 父 pom 已自动写入，22/22 插件 jar 实测都有），加了是 no-op。见 §8。 +2. 被拒插件是否要出现在 `information_schema.extensions`（带状态列）——本次不做， + 若运维反馈诊断困难再议。 +3. 第三方插件作者文档：需说明 §3.2 的 bump 纪律与"SPI 表面变化必须重编"的预期， + §12.4 的 pom 片段可直接作为素材。 +4. 考虑发布一个插件 parent pom（如 `doris-connector-plugin-parent`），预置 property 与 + `manifestEntries` 配置，第三方继承即自动正确，免去 §12.4 手写和写错的风险。 + Trino 的 `trino-plugin` packaging 是同一思路。本次不做——它是新增发布物， + 且要先有真实的第三方插件需求才能定其形态。 + +--- + +## 14. 实现记录（2026-07-29 完成） + +状态：**已实现并验证**。以下是实现相对本设计的偏差与理由，凡与设计不同的都在此列明。 + +### 14.1 与设计一致的部分（不赘述） + +§3 判定规则、§4 单一来源（property → filtered resource + manifest）、§5 校验点与 fail-closed、 +§6 旧机制删除、§7.1 四族基线冻结范围、§10 改动清单，均按设计落地。四族版本号起始 `1.0`。 +~~AUTHENTICATION / LINEAGE 按设计**只加 property、不加 ``**~~ —— **这条已在 +§14.8c 推翻**：不加 `` 会让版本号从 maven build-cache 的哈希输入里消失， +bump 之后 `clean package` 会恢复出带旧版本的陈旧 jar（已复现）。四族现在**一律**都加。 + +### 14.2 偏差一：门禁按"族名"派生，而不是传三个字面量 + +`ApiVersionGate.forFamily(String family, Class spiAnchor)` 只收族名（`connector`）与 +SPI 锚点类型，资源路径与 manifest 属性名按约定派生： + +``` +family = "connector" + → 资源 /META-INF/doris/connector-plugin-api-version.properties （键统一为 api.version） + → 属性 Doris-Connector-Plugin-Api-Version +``` + +理由：设计要求 loader 族中立，而"族中立"用一条成文约定表达比在四个管理器里散落 12 个字面量 +更难写错。代价是 `grep Doris-Connector-Plugin-Api-Version` 只能命中 pom，命不中 Java；用 +`ApiVersionGateTest` + `PluginApiVersionWiringTest` 把四个派生结果**逐字钉死**补偿。 + +**残留人工环节**：pom 里的 `` 是 XML 元素名，无法由属性 +插值，因此它与派生规则的一致性没有任何构建期检查。两处测试把期望字面量写出来供评审对照。 + +### 14.3 偏差二：`loadAll` 的门禁参数是**必填**（owner 签字） + +`DirectoryPluginRuntimeManager#loadAll` 由 4 参改 5 参，`Objects.requireNonNull(apiVersionGate)`。 +否决了"保留 4 参重载、gate 可空"——可空重载等于留了一个"不传就不校验"的静默旁路，正是 §1 +要消灭的失效模式。代价是改了 6 处调用点（4 个生产管理器 + 2 个测试，含 +`AuthenticationPluginManagerTest.StaticRuntimeManager` 的 override）。 + +### 14.4 偏差三：表面基线**记录返回类型**（owner 签字） + +行格式 `<冻结类型>#<方法名>(<参数类型>):<返回类型>`，与既有 +`connector-metadata-methods.txt`（只有 `名(参数)`）不同。理由：§3.2 把"改返回类型"定义为 +major，不记返回类型就漏掉这一整类。既有那个基线**本次不动**。 + +另一个取舍：每行以**被冻结的根类型**为键，而不是 `getDeclaringClass()`。即 +`ConnectorProvider#description():java.lang.String` 与 +`PluginFactory#description():java.lang.String` 同时出现。这样"插件在这个类型上能调到什么" +被完整钉住，而把 default 方法在父接口链上挪位置（对实现方无感）不会误报。 + +四份基线规模：connector 49 行、filesystem 64 行、authentication 22 行、lineage 16 行， +其中 fe-extension-spi 的 `Plugin`/`PluginFactory`/`PluginContext` 共 **7** 行**四份都有** +（四份基线取交集实测正好这 7 行）——改它们四个基线同时红，各自要求 bump 自己那个 property， +即 §3.3 要的效果。 + +### 14.5 偏差四：测试分层与设计 §9 不同 + +设计 §9 要求"加载器级（每族一个）"造临时 jar。实现改为： + +| 层 | 位置 | 内容 | +| --- | --- | --- | +| 判定规则 | `ApiVersionGateTest`（fe-extension-loader，13 例） | major 相等/不等、minor 双向、patch

It is the weight base, computed even under count pushdown where + the file-splitting size (`effectiveSplitSize`) is 0. + - **Existing test call-sites of the changed signatures MUST be updated** (else compile break): + `PaimonScanPlanProviderTest` calls `buildNativeRange` (~4 sites) and `buildNativeRanges` (~2 sites) + directly — append the `weightDenominator` arg (any value, e.g. `64L*1024*1024`; those tests assert only + URI-normalization / DV-on-every-sub-range, both denom-independent).

The connector owning its denominator is both simpler and + correct; do NOT later "simplify" the SPI getter away. + +## No-regression / correctness + +- **Other connectors unchanged:** sentinel `-1` default → `PluginDrivenSplit` leaves both FileSplit fields + null → `getSplitWeight()` = `standard()` exactly as today.

The ONLY behavioral delta vs today is: **the `schemaAt` schema-file read is +skipped on a repeat**. `resolveTable` and `buildTableSchema` still run every query (unchanged). + +### Components + +1. **New tiny class `PaimonSchemaAtMemo`** (package-private, in `fe-connector-paimon`): + - Storage = plain **`ConcurrentHashMap`** (matches the + module convention — the only long-lived caches in fe-connector-paimon are plain `ConcurrentHashMap`, + `PaimonConnector.java:81-82`; lock-free reads; no new dependency). + - **`MemoKey`** = immutable holder of the handle's **extracted identity** `(databaseName, tableName, + sysTableName, branchName, schemaId)` built in `new MemoKey(PaimonTableHandle handle, long schemaId)`. + It mirrors `PaimonTableHandle.equals/hashCode`, which key on exactly + `(databaseName, tableName, sysTableName, branchName)` (`PaimonTableHandle.java:233-240`, `scanOptions` + correctly excluded from identity). **Extracted fields, NOT a retained handle reference** — deliberate: + a `PaimonTableHandle` carries its loaded paimon `Table` (`setPaimonTable`), so retaining the handle as + a map key would pin that `Table` (catalog/schema/IO refs) in the cache for its lifetime. Extracting the + four `String`/`long` identity fields avoids that memory pin at the cost of a documented sync-point with + the handle's identity (a comment in `MemoKey` points to `PaimonTableHandle:233-240`). This is a + deliberate deviation from the red-team's "delegate to handle.equals" suggestion, which did not account + for `Table`-pinning. Branch is load-bearing (same schemaId on different branches = different schema; + `branchName` is live on the pinned handle via `applySnapshot→withBranch`). `sysName` is a forward-compat + guard (sys tables don't reach this path today, but a key collision would be a correctness bug). + - **Bound (best-effort, honors task-list "bounded (maxSize)"):** before a `put`, if `size() >= MAX`, + `clear()` the map. Crude but correct: values are immutable, so a flush only causes re-reads + (= today), never a stale/wrong value. The keyspace is `(table, branch, schemaId)` — naturally tiny — + so this safety valve effectively never fires; `MAX` is a generous constant (proposed `10000`). The + map is also freed wholesale on REFRESH (connector rebuild). + - `PaimonSchemaSnapshot getOrLoad(PaimonTableHandle handle, long schemaId, Supplier loader)`: + ``` + MemoKey k = new MemoKey(handle, schemaId); + PaimonSchemaSnapshot hit = cache.get(k); // lock-free + if (hit != null) return hit; + PaimonSchemaSnapshot loaded = loader.get(); // the schemaAt I/O — OUTSIDE any lock + if (cache.size() >= MAX) { // best-effort bound + cache.clear(); + } + PaimonSchemaSnapshot prev = cache.putIfAbsent(k, loaded); + return prev != null ? prev : loaded; // canonicalize on a concurrent race + ``` + The loader runs without any lock (no I/O-under-lock, no `computeIfAbsent`). A concurrent same-key + miss may double-load (rare) — harmless: the value is immutable and identical (same schemaId), and a + double-load equals today's two independent per-query loads, never worse.

(Minor: a `t` query and a + `t$ro` query don't share — different sysName — so `$ro` re-reads the base schemas once. Acceptable; rare.) +- branch: both writers key by `(db, table, branch)` and both read the branch FileStoreTable's + `schemaManager.schema(id)` (the same write-once branch schema file) — identical value. + +**Loader keeps the DIRECT read (not `catalogOps.schemaAt`)** so the existing real-`FileStoreTable` + +fake-`catalogOps` tests are unaffected (the schema-evolution tests build a real `FileStoreTable` via +`FileSystemCatalog` but construct the provider with a `RecordingPaimonCatalogOps`; routing the read through +`catalogOps.schemaAt` would break them).

MinIO is +literally "S3 with a custom endpoint." The only deltas are (a) the alias key prefix and (b) three +tuning defaults + the region default. Precedent: `CosFileSystemProvider`/`CosFileSystemProperties` +is a *dedicated* provider only because COS emits genuinely COS-specific Hadoop keys +(`fs.cosn.*`, `fs.cos.impl`) and uses a Tencent native SDK in `CosObjStorage`. MinIO emits **none** — +a dedicated provider would be a near-empty clone of S3, pure duplication for no behavioral gain. + +**The one caveat — differing tuning defaults — and why it does not block aliasing.** +`ConnectorProperty` defaults are *field-level*, applied whenever no alias for that field is present +in the raw map (`ConnectorPropertiesUtils.bindConnectorProperties` only `field.set`s when a name +matched). They cannot be conditionalized on *which* alias matched. So I cannot make +`maxConnections` default to `50` for an `s3.*` catalog and `100` for a `minio.*` catalog purely by +adding aliases. Resolution: **add `minio.*` as aliases on the existing tuning fields and accept the +S3 defaults (50/3000/1000) for a `minio.*` catalog that omits the tuning keys.** Justification: + +- The tuning values are connection-pool/timeout knobs; both sets are functional against MinIO. The + legacy MinIO values (100/10000/10000) were never documented as required for correctness — they are + a historical default, not a contract. +- A `minio.*` catalog that *explicitly* sets `minio.connection.maximum` etc. is honored exactly + (the alias binds the value). Only the *unset* case differs, and only in pool size / timeouts. +- Conditionalizing the default would require post-bind logic ("if a `minio.*` alias matched and the + tuning key was absent, override to 100/10000/10000") — added complexity in shared code, touching + the s3 hot path, to preserve a non-contractual default. Not worth the blast-radius risk. + +This is the single intentional, documented behavioral deviation from legacy MinIO. It is called out +in Risk Analysis and Open Questions for the main agent to ratify. **Region default `us-east-1` IS +preserved** — `S3FileSystemProperties.normalizeForLegacyS3Compatibility()` already derives +`region = DEFAULT_REGION ("us-east-1")` when an endpoint is set but region is blank +(`S3FileSystemProperties.java:360-362`), exactly matching legacy MinIO's `region="us-east-1"` +default behavior for the common endpoint-only case. (Field-level default of legacy is `us-east-1` +unconditionally; the SPI achieves the same effective value for endpoint-only configs and for +region-only/AWS-endpoint configs derives the real region — strictly better.) + +## Ordering invariant (load-bearing for s3.* byte-parity) + +`ConnectorPropertiesUtils.getMatchedPropertyName` (`ConnectorPropertiesUtils.java:96-108`) returns +the **first** name in the annotation's `names()` array that is present in the map. Therefore **all +`minio.*` aliases MUST be appended at the END of each field's existing `names()` list.** With +`minio.*` last, an `s3.*`-keyed (or `AWS_*`-keyed) catalog binds exactly as today even if it also +happened to carry a `minio.*` key — `s3.endpoint` outranks `minio.endpoint`.

个常量；二选一：①`provided`（不打包）；②直接内联这 4 个 key 字符串，连这个依赖都省掉——**推荐内联**，使新模块零 hadoop 依赖）。 +- **无** hadoop-common / aws-sdk / iceberg / paimon / fe-common / fe-thrift / fe-grpc。 +- `fe/pom.xml`：`` 加

import-gate。`fe-property` 让连接器**直接做**归一化（无需回调引擎），未来可逐步替代这些桥方法（含 vended：把 per-table token map 直接喂 `StorageProperties.create`）。**本期不动这些桥**，仅新增 fe-property 并迁移 `applyStorageConfig` 重抄段；桥方法待全面迁移后再评估下线。 + +## 10. 边界与坑（Edge Cases） + +1. **`S3URI`**：旧 `S3PropertyUtils` 依赖 fe-core 的 `common.util.S3URI`。新模块**拷贝** `S3URI` 进 `org.apache.doris.property.storage`（纯 java，仅把 UserException 换 StoragePropertiesException）。 +2. **HdfsClientConfigKeys**：见 §8，推荐内联 4 个 key 常量，避免 hadoop 依赖。 +3. **Azure OAuth**：旧 `AzureProperties` OAuth 分支构造 `Configuration`；新版产出 `fs.azure.account.oauth.*` Map。 +4. **鉴权（kerberos）**：旧 `HdfsProperties` 构造 `HadoopAuthenticator`（fe-common）。新版**只解析**鉴权属性（auth type / principal / keytab / 归一化 hadoop.* Map），**不构造** authenticator——authenticator 是运行时对象，由连接器/引擎（`ConnectorContext.executeAuthenticated`）负责。借此甩掉 fe-common 依赖。 +5. **`guessIsMe` 选型顺序**：MinIO 让位 Azure/COS/OSS/S3 的探测顺序需原样保留（否则误判后端）。 +6. **`HttpProperties` 误引**：旧版误 import `org.apache.hudi...MapUtils`；新版改 commons-collections4，避免拖 Hudi。 +7. **凭据 provider 构造下移**：`AwsCredentialsProviderFactory`（aws-sdk）不进 fe-property；连接器需要 provider 时自建（多数场景连接器只需把 Map 灌 Configuration / 发 BE，并不需要 provider 对象）。 + +## 11. 测试与回滚 + +- **平价测试（关键）**：对每个 storage 子类，用同一组 raw props 跑"新 `getHadoopConfigMap()`/`getBackendPropertiesMap()`" vs "旧 `getHadoopStorageConfig()` 转成 Map / `getBackendConfigProperties()`"，断言**键值完全一致**（含 minio/oss/cos/obs/azure/hdfs）。这是防漂移的核心闸。 +- **单元测试**：选型 `guessIsMe` 顺序、URI 归一化、ParamRules 校验、各 alias 解析、minio.* 专属前缀检测。 +- **连接器迁移验证**：paimon 改用 fe-property 后，跑 `external_table_p0/paimon` 回归（minio/oss/s3 catalog 读）。 +- **回滚**：strangler-fig 天然可回滚——任一连接器迁移出问题，单独回退该连接器到旧 `applyStorageConfig`，fe-property 与旧 property 并存互不影响。 + +## 12. 风险与备选 + +- **风险1：平价漂移**。新 Map 推导若与旧 Configuration 落键有差→连接器/BE 行为变。缓解=§11 平价测试逐键断言；首迁 paimon 用真实 minio/oss 回归。 +- **风险2：代码拷贝双维护**。并存期 storage 逻辑两份。缓解=并存窗口尽量短、优先迁 paimon 验证范式、平价测试钉死一致；新代码为权威，旧代码进入"只读冻结"。 +- **风险3：plugin-zip 漏打 fe-property**。缓解=迁移连接器时同步改 assembly，加一条 smoke（plugin 加载 `org.apache.doris.property.storage.StorageProperties` 不 ClassNotFound）。 +- **备选A（被否）**：原地 lift-and-shift 整个 datasource.property → 循环依赖 + vendored glue + 重型 SDK，已证不可行（见前置研究报告）。 +- **备选B**：把新代码直接塞进 fe-foundation。否决——会破坏 fe-foundation 零依赖基座（即使首期 storage 很轻，后续 metastore 会重）。保持 fe-foundation 为纯基座，fe-property 为其上一层。 + +## 13. 有序 TODO 列表 + +**M1 — 模块骨架** +1. 新建 `fe/fe-property/pom.xml`（仿 fe-foundation；compile=fe-foundation+commons-lang3+guava+log4j-api）。 +2. `fe/pom.xml` `` 加 `fe-property`（fe-foundation 后）；dependencyManagement 加条目。 +3. 建包 `org.apache.doris.property.storage`（+ `storage` 内 util）。 + +**M2 — 拷贝并重适配 storage（核心）** +4. 拷贝 `ConnectionProperties`（基类，去掉 `loadConfigFromFile` 对 fe-common 的依赖或改 foundation 等价）→ 新包。 +5. 拷贝 `StorageProperties` 抽象类：把 `getHadoopStorageConfig():Configuration` 改 `getHadoopConfigMap():Map`、`initializeHadoopStorageConfig()` 改 `buildHadoopConfigMap()`、`UserException`→`StoragePropertiesException`、`getBackendConfigProperties`→`getBackendPropertiesMap`。 +6. 拷贝 `AbstractS3CompatibleProperties` + `ObjectStorageProperties` + `Abstract*`：移除 `getAwsCredentialsProvider()`（aws-sdk），改产出凭据 getter；S3 系 fs.s3a.* 改写进 Map。 +7. 拷贝 13 个具体类（S3/OSS/COS/OBS/MinIO/GCS/Ozone/Hdfs/OSSHdfs/Azure/Broker/Local/Http）：逐个把 `conf.set(...)` 改为 `map.put(...)`；保留 `guessIsMe` 顺序；修 HttpProperties 的 hudi 误引。 +8. 拷贝 util：`S3PropertyUtils`、`HdfsPropertiesUtils`（内联 `HdfsClientConfigKeys` 4 常量）、`AzurePropertyUtils`、**`S3URI`**（新拷贝）、`exception/AzureAuthType`。 +9. 移除 `S3Properties` 的 proto/thrift 方法（不移植）。 + +**M3 — 测试** +10. 平价测试：每个子类新 vs 旧逐键断言（依赖 fe-core 旧类做基准，可放 fe-property 的 test 或一个临时对照 test）。 +11. 单元测试：guessIsMe 顺序、URI 归一化、minio.* 检测、ParamRules、alias。 +12. checkstyle 0 告警。 + +**M4 — 首个连接器迁移（paimon，验证范式）** +13. `fe-connector-paimon` 加 `fe-property` 依赖；plugin-zip assembly include fe-property。 +14. `PaimonCatalogFactory`：删 `applyStorageConfig`/`applyCanonicalMinioConfig`/OSS/COS/OBS 块/`MINIO_*_ALIASES`，改为 `StorageProperties.create(props).getHadoopConfigMap().forEach(conf::set)`。 +15. 跑 import-gate（`tools/check-connector-imports.sh`）确认无违规；跑 paimon 回归（minio/oss/s3）。 + +**M5 — 文档与收尾** +16. 更新

`import`。commit `e7eae85faa4` 的 host `hive-exec:core` 是 CREATE FUNCTION 的 `hive.ql.exec.UDF` 契约，主机侧独立事，与插件无关。 +2. **DLF 已是死代码**，直接不装。`iceberg.catalog.type=dlf` / `metastore.type=dlf` 已在

→ 命中补丁客户端 → 二者须共用同一份重定位 thrift + 元数据 API 类身份 → 必须一个共享 shade。代价：hive/hudi 多背 ~1.1MB 永不加载的 iceberg 类（非泄漏，仅字节）。 +> - **D2 = 3.1.3** ✅ 用户签字。保持与全局 shade 行为一致。 +> - **D3 = 复用 `shade.doris.hive.org.apache.thrift`** ✅ 用户签字。补丁客户端 + `ThriftHmsClient` 本就 import 此前缀 → **零源码改动**；过渡期两包同名同版本（libthrift 0.9.3）字节一致、谁生效都不撕裂（新前缀反而会在过渡期让新旧两份 `HiveCatalog` 绑不同前缀 → 旧份被优先加载即 ClassCastException）。 +> - **D4 = KEEP_IN_HMS**（`javap` 定案）。补丁客户端字节码对 thrift 的全部 48 处引用**已全部是重定位名** `shade.doris.hive.org.apache.thrift.*`，零 raw、零按名反射。故它留在 `fe-connector-hms`、不搬进 shade、不改写，只需精简 shade 在其 classpath 上复现同名 thrift 即可。 +> +> **配套计划微调（红队条件 1）**：iceberg **摘全局 shade** 与 **接精简 shade** 须放**同一次提交（原子切换）**，消除"过渡期两份 `HiveCatalog` 并存"的不确定（实测全局 37821B vs 精简 1.10.1 37853B，谁生效随 classpath 序 → 顺带把 iceberg.hive 对齐插件自带 iceberg-core 1.10.1）。 +> **验证条件（红队条件 2）**：Phase 1/4 须跑重部署类加载冒烟（每插件 `metastore.api.Table` 与 `shade.doris.hive.org.apache.thrift.TException` **各仅一份**）+ hive/hudi/iceberg-on-HMS e2e +

+ `hive-common` + `libthrift`（重定位）**外加 `iceberg-hive-metastore`**。`fe-connector-hms` 和 `fe-connector-iceberg` 都依赖它。iceberg-hive-metastore 随包搭车 → hive/hudi 多背 ~1 MB 用不到的 iceberg 类，但**只需一个 thrift 私有命名空间**、最省事、就是「全局 shade 去肥」版。 +- **选项 B（分开）**：`fe-connector-hms-hive-shade`（客户端+thrift，hive/hudi/iceberg 共用）+ iceberg 的 iceberg-hive-metastore 单独 shade。**难点**：iceberg-hive-metastore 的 `HiveCatalog` 必须和客户端用**同一份**重定位 thrift，而 `libthrift` 不能在两个 shade 各 bundle 一份（child-first 重复类）。要么 iceberg-hive-metastore 进同一个 jar，要么引用 hms shade 的重定位 thrift 而不重打包 → 复杂。 +- **建议**：选 A。Phase 0 交用户签字。 + +### D2 —

凭据在插件路径同样经 fe-core `IcebergVendedCredentialsProvider`（工厂 Type.ICEBERG 分支），但该类只 import iceberg-core 类型，不钉 aws 依赖。 + +**剥离步骤**（每步独立可落地）： +1. 删 5 个连通性 tester（AbstractIcebergConnectivityTester + 4 子类）+ `CatalogConnectivityTestCoordinator.java:284-304` 死臂——test_connection 已由连接器承接（实证 FULLY），tester 不 import aws，纯清理。 +2. 剥属性类中的死方法：AbstractIcebergProperties.toFileIOProperties/buildIcebergCatalog、IcebergGlue/S3Tables/DLF 各自的 initCatalog 及 helper（org.apache.iceberg.aws 与 s3tables import 全部集中于此；插件路径只用 initNormalizeAndCheckProps，initCatalog 只有死掉的原生 catalog 构建路径调用）。 +3. 处理唯一活的 aws 引用：`addGlueRestCatalogProperties` 的 glue/s3tables REST 签名属性规范化——就地内联所需常量（几行字符串键）或下沉连接器侧，消除对 iceberg-aws 类型的 import。 +4. 删 IcebergS3TablesMetaStoreProperties（+2 测试 + tester）后同 commit 摘 `s3tables` + `s3-tables-catalog-for-iceberg`；删 IcebergAws* helper、DLFCatalog 后摘 `iceberg-aws`。 +5. ⚠️ 决策点 §8-Q2：摘 iceberg-aws

IcebergExternalDatabase/Table/SysExternalTable + IcebergExternalCatalog（常量已于阶段一搬家）。规模 ~75-100 文件。 + +--- + +## 6. 阶段四：架构迁移（Trino 参照） + +### 6a. HMS-iceberg（最大阻塞，钉住 iceberg-core + ~24 文件） +Trino 方案：**hive 插件零 iceberg 代码**——引擎提供通用表重定向钩子 `ConnectorMetadata#redirectTable(session, tableName) → Optional`，hive 元数据层检测表属性 `table_type=ICEBERG` 后把表重定向到配置的 iceberg 目录（`hive.iceberg-catalog-name`），后续全部规划/读写走 iceberg 连接器。 +Doris 可借鉴的两条路： +- **路 A（Trino 式重定向）**：fe-core 加中立"表重定向"接缝，HMS 目录检测 DlaType.ICEBERG 后把表委给同集群的插件 iceberg 目录处理。优点：不必等 hive 整体迁 SPI；缺点：需要用户侧有/隐式建一个对应 iceberg 目录，跨目录语义（权限/缓存/SHOW）要设计。 +- **路 B（随 hive 整体迁移）**：hive 进 SPI_READY_TYPES 时 HMS-iceberg 自然进插件（fe-connector-hive/fe-connector-hms 方向）。优点：无新架构面；缺点：时间表最远。 +无论哪条，落地后连锁解放：IcebergUtils、IcebergMetadataOps、IcebergExternalMetaCache、source/ 全部、cache/、profile/、IcebergDlaTable、IcebergTransaction 残留、vendored DeleteFileIndex（+ checkstyle

对应改造（不必推翻签字决策，可先"去 iceberg SDK 化"）：把 IcebergMergeOperation 的操作码、IcebergRowId/IcebergMetadataColumn 的行标识抽象改为 fe-connector-api 中立类型（两个小增项：中立 merge 操作码枚举 + 行标识列描述，SPI 带默认实现），IcebergNereidsUtils 中 SDK 表达式转换下沉连接器；`StatementContext.java:323` 的 `List` 暂存改为不透明句柄。做完后该车道虽仍在 fe-core，但**不再 import org.apache.iceberg**——iceberg-core 摘除不再被它阻塞（只剩 6a）。 + +> **⚠️ 2026-07-04 晚实证重裁定（11-agent 设计研究 +

+### 起因 + +用户提出独立调研任务：fe-core `datasource/property/` 下的 `common` 和 `metastore` 两个目录， +能不能删掉、或者迁进 `fe/fe-connector`？给出方案或给出不能的理由。 +背景原则：元数据服务（Glue 之类）归 `fe-connector-metastore-api`，存储（hdfs/s3 之类）归 `fe-filesystem`。 +用户明确要求「不要局限于当前逻辑，必要时可增删任意模块的接口」。 + +### 做法 + +Workflow 编排：8 路并行侦察（产出 172 条 finding）→ 3 路独立设计 +（minimal / architectural / risk 三种视角，**结论并不一致**）→ 6 项对抗验证（每项被推翻后再走第二轮独立复核） +→ 综合。之后由本 session 对**承重结论逐条亲自复核代码**（不只采信 agent）。 + +三份设计的裁决分歧本身是有信息量的： + +| 视角 | `common/` | `metastore/` | +|---|---|---| +| minimal | KEEP | DELETE | +| architectural | DELETE_AND_REDIRECT | DELETE | +| risk | KEEP | DELETE_AND_REDIRECT | + +⇒ `metastore/` **三路一致要删**；`common/` **2:1 主张留**，且主张删的那路（architectural） +自己也承认需要用户先拍两个板。最终采纳「留」。 + +### 结论 + +- **`metastore/`（4 文件 333 行）→ 整体删除**，连带孤儿 `ConnectionProperties.java`（140 行）。 + 运行期两道门都不可达；包里本来就零解析（唯一注册的 `TrinoConnectorPropertiesFactory` 连 + `initNormalizeAndCheckProps()` 都不调）；持久化无坑；接班人 + （`fe-connector-metastore-api` 的 `MetaStoreProperties` + `MetaStoreProviders.bind` + + `Connector.deriveStorageProperties`）早已在生产路径上跑着 ⇒ **没有任何东西需要搬**。 +- **`common/`（2 文件 237 行）→ 留在 fe-core，只砍死的一半（~146 行）**。 + 它服务的是**内部存储**（冷存 StoragePolicy / 云上 StorageVault / TVF / backup / export）， + 零个 fe-connector、零个 fe-filesystem 模块 import 它 —— **根本不在这次迁移的射程内**。 + +### 🔴 踩坑记录（最有价值的部分） + +**坑 1 —— 「重复造轮子」的误判，被对抗验证两轮推翻。** +我的初判是：`common/` 和 `fe-filesystem-s3-base` 的 +`S3CredentialsProviderType`/`S3CredentialsProviderFactory` 是同一套逻辑的两份副本， +应该「删除 + 把消费者指向现成实现」。**错。** 两条活的行为差异： +① 发给 hadoop 的凭证串会多出 `ProfileCredentialsProvider`； +② 模式串接受面放宽（空串 / `ENVIRONMENT` / `WEB_IDENTITY_TOKEN_FILE` 从抛异常变成接受， +而 `StorageAdapter.java:169-170` 注释明说这个严格是**故意的**）。 +**且全仓没有任何测试钉住那个串** ⇒ 换掉会绿着上线一个回归。 +**通用教训**：「两个类长得像 ⇒ 可以合并」是个高频误判；判定等价必须**逐字段比对输出** +（尤其是会发到 BE / 写进 hadoop conf 的**字符串**），而不是比对结构。 +顺带一提，仓库里其实有**四份**这套逻辑（第三份在 `fe-connector-iceberg`，第四份在 +`fe-connector-metastore-iceberg`），而且第三份的语义又和前两份都不同（未知模式回退 DEFAULT 而非抛）。 + +**坑 2 —— 对抗验证抓到「两份候选设计会挂在 checkstyle 上」。** +`fe/pom.xml:177-183` 把 checkstyle `check` 绑到**每个模块的 validate 阶段**， +`checkstyle.xml:167` 开着 `UnusedImports` 且 `severity=error` ⇒ +**漏删一个 import，不带 flag 的 `mvn test` 会在跑任何测试之前就中止**。 +三份设计里两份的 import 清单是错的（漏了 `CatalogProperty.java:25` 的 `Preconditions`； +另有一份把 `StorageAdapter` 的 import 错记到 `AwsCredentialsProviderFactory` 头上）。 +`tasklist.md` 里是**修正后**的精确清单。 + +**坑 3 —— 调研报告自己给的 HIGH 风险缓解方案，复核后是无效的。** +报告主张「把 `setPluginDerivedStorageDefaultsSupplier` 语句提前到造连接器之前」来关闭 +null-supplier 窗口。复核发现**修不干净**：提前之后 lambda 捕获的 `connector` 字段仍是旧值/null +（`connector = newConnector` 发生在 `createConnectorFromProperties()` 返回**之后**）， +窗口内照样得到 `emptyMap`。 +更进一步，我逐个复核了四个连接器的构造函数（paimon `:151-166` / iceberg `:215+` / hive / hudi）， +**没有任何一个在构造期碰 storage**（都只传惰性方法引用 `this::pluginAuthenticator`）， +`validateProperties` 还显式传 `Collections.emptyMap()` ⇒ **这个窗口今天根本不可达**。 +所以它不是 blocker，而是「删完之后要 fail-loud 还是 fail-silent」的选择题 → 收敛成 **OD-1**。 +**通用教训**：**调研报告（哪怕是自己多轮对抗产出的）的「风险 + 缓解」也要复核**， +高危标注可能是理论可达性而非真实可达性，配的解法可能治标不治本。 + +### 产出 + +本任务空间

**上游活、本分支死**。 + +**为什么这翻转了结论**：`StorageAdapter.java` 本身两边都在，会走 rebase 三方合并。 +今天上游改动该区域能干净合入；删掉方法后，这些改动就变成**每次 rebase 的人工冲突 hunk**， +而收益只是 146 行本就不执行的代码 —— 对一个**定期 rebase 到 force-push 上游**的分支， +这笔账不划算。

Test #3 uses + `verbose(true)` and just asserts the literal substring `deleteFileNum` exists. + +3. **`paimonNativeReadSplits=/`** — paimon-specific, produced by the legacy override + `PaimonScanNode.getNodeExplainString:656-658`: + ``` + sb.append(String.format("%spaimonNativeReadSplits=%d/%d\n", + prefix, rawFileSplitNum, (paimonSplitNum + rawFileSplitNum))); + ``` + `rawFileSplitNum` (native ORC/Parquet sub-splits) and `paimonSplitNum` (JNI + non-DataSplit + count + splits) are accumulated in `PaimonScanNode.getSplits` (`:393,465,477`).

The counts must be + re-derived by the node from the returned ranges. Under `force_jni_scanner=true` (tests #4/#5), the + native arm is never taken → `rawFileSplitNum=0`, exactly one JNI split → `0/1`. + +4. **`predicatesFromPaimon:` / `PaimonSplitStats:`** — also emitted by the legacy override + (`PaimonScanNode.getNodeExplainString:660-687`). NOT asserted by any of the 5 failing tests, so out of + scope (but see Risk §"completeness" — re-emitting them is harmless and improves parity). + +**Ordering note (verified):** `FileQueryScanNode.finalizeForNereids` (`:236`) → `createScanRangeLocations` +(`:312`) → `getSplits(numBackends)` (`:415`) runs during planning, BEFORE explain renders.

Instead, **selectively re-emit** the two +FileScanNode line families that are paimon-asserted, keeping the existing custom header: + +- **`pushdown agg=COUNT (n)`**: after the connector `appendExplainInfo` call, emit + ``` + output.append(prefix).append("pushdown agg=").append(getPushDownAggNoGroupingOp()); + if (getPushDownAggNoGroupingOp() == TPushAggOp.COUNT) { + output.append(" (").append(getTableLevelRowCountForExplain()).append(")"); + } + output.append("\n"); + ``` + This line is connector-agnostic and safe to emit for ALL plugin connectors (it mirrors what + FileScanNode prints for every other scan node — its absence on plugin nodes is itself an inconsistency). + **No gating needed** for the `pushdown agg` line; it is universally correct. + - Requires the count value to reach the node. See Change C. + +- **`dataFileNum/deleteFileNum/deleteSplitNum`** (VERBOSE block): this is the expensive per-BE loop in + `FileScanNode:151-213`. Rather than duplicate ~60 lines, factor the VERBOSE per-BE block out of + `FileScanNode.getNodeExplainString` into a `protected` helper + `appendBackendScanRangeDetail(StringBuilder, prefix)` and call it from `PluginDrivenScanNode` under the + same `detailLevel == VERBOSE && !isBatchMode()` gate. (Surgical alternative if extraction is undesirable: + copy the block; but extraction avoids drift and is preferred by Rule 3's "don't fork" reading.) The block + calls `getDeleteFiles(rangeDesc)` — see Change B for the plugin override. + +### Change B — `getDeleteFiles` override on the plugin node, via a generic seam + +`PaimonScanRange.populateRangeParams` already sets `TPaimonFileDesc.setDeletionFile(...)` on the thrift +range from the `paimon.deletion_file.path` property. The deletion-file path is therefore present in the +serialized `TFileRangeDesc` at explain time. Override `getDeleteFiles(TFileRangeDesc rangeDesc)` on +`PluginDrivenScanNode` to read it. + +Two options for keeping it generic (the node is shared): +- **Option B1 (preferred):** add a default SPI hook + `ConnectorScanPlanProvider.getDeleteFiles(TFileRangeDesc) -> List` returning `emptyList()` by + default; `PaimonScanPlanProvider` overrides it to read `TTableFormatFileDesc.getPaimonParams() + .getDeletionFile().getPath()` (a verbatim port of legacy `PaimonScanNode.getDeleteFiles:337-357`). The + node's override delegates to `connector.getScanPlanProvider().getDeleteFiles(rangeDesc)`. This keeps the + thrift-shape knowledge in the paimon connector and leaves es/jdbc/mc returning empty (no `deleteFileNum` + change — though their VERBOSE block still won't print unless they also opt in, see gating below). +- **Option B2 (rejected):** read `TPaimonFileDesc` directly in fe-core's `PluginDrivenScanNode`. Rejected: + bakes paimon thrift knowledge into the shared node, and the legacy fe-core PaimonScanNode already imports + `TPaimonDeletionFileDesc`/`TPaimonFileDesc` so the precedent exists, but B1 is cleaner for the SPI. + +### Change C — thread the count-pushdown sum back to the node + +`PaimonScanPlanProvider` already encodes the summed count on the single collapsed count range as the +`paimon.row_count` property (`PaimonScanRange` builder `.rowCount(...)` → `props["paimon.row_count"]`, +consumed BE-side by `populateRangeParams:202-205`). In `PluginDrivenScanNode.getSplits`, after building the +`PluginDrivenSplit`s, scan the ranges and, if `countPushdown` is active, read `paimon.row_count` from the +range properties and call `setPushDownCount(sum)`. Generic implementation (no paimon import): +``` +if (countPushdown) { + for (ConnectorScanRange r : ranges) { + String rc = r.getProperties().get("paimon.row_count"); // generic key lookup + if (rc != null) { setPushDownCount(Long.parseLong(rc)); break; } + } +} +``` +For deletion_vector tables no count range is emitted → no `paimon.row_count` → `tableLevelRowCount` stays +`-1` → `pushdown agg=COUNT (-1)`. Correct. + +The property key `paimon.row_count` is paimon-specific but harmless to look up generically (absent for +other connectors). To avoid hard-coding a paimon key in the shared node, optionally promote it to a generic +`ConnectorScanRange` getter `getPushDownRowCount() -> long (default -1)` that `PaimonScanRange` overrides +from its `rowCount` field; the node reads `r.getPushDownRowCount()`. **Preferred:** the generic getter, to +keep the shared node connector-agnostic (consistent with Rule 11). + +### Change D — accumulate native/jni split counts and emit `paimonNativeReadSplits` + +`paimonNativeReadSplits` is intrinsically paimon-specific. Emit it from the connector via a NEW +`appendExplainInfo` override on `PaimonScanPlanProvider` — BUT `appendExplainInfo` only receives the +`nodeProperties` map, NOT the per-scan split counts (those are computed in `planScan`, after +`getScanNodeProperties`). So the counts must be threaded through the node. + +Chosen approach: classify ranges in `PluginDrivenScanNode.getSplits` (where ranges are already iterated) +and stash counts, then emit via the connector's `appendExplainInfo` by passing them through a small +augmented props map, OR — simpler and matching legacy — have the connector own the string but feed it the +counts. Concretely: + +- A native range = `ConnectorScanRange` whose `getRangeType()` is `FILE_SCAN` with a `getPath()` present + and NO `paimon.split` property (paimon native sub-splits set `path`/`fileFormat`, no `paimon.split`). +- A jni/count range = has the `paimon.split` property. + +Cleanest generic seam: add `ConnectorScanRange.isNativeReadRange() -> boolean (default false)` that +`PaimonScanRange` overrides (`true` when `paimon.split == null && path != null`). In +`PluginDrivenScanNode.getSplits`, after building splits, compute +`nativeCount = count(isNativeReadRange)` and `totalCount = ranges.size()`, store in two node fields +(`int rawFileSplitNum`, `int totalSplitNum` — generic names; or a single `scanRangeReadStats` map). Then in +`getNodeExplainString`, pass these to the connector via `appendExplainInfo`. Since `appendExplainInfo`'s +signature is `(StringBuilder, String prefix, Map nodeProperties)`, thread the counts by +**adding them into a copy of the props map** the node passes to `appendExplainInfo` (e.g. +`__native_read_splits` / `__total_read_splits` synthetic keys), and have `PaimonScanPlanProvider +.appendExplainInfo` read them and emit `paimonNativeReadSplits=raw/total`. This keeps the paimon string in +the paimon connector and needs no SPI signature change. + +**Gating:** `appendExplainInfo` is already connector-dispatched (only the active connector's provider runs), +so `paimonNativeReadSplits` is emitted ONLY for paimon. es/jdbc/mc providers do not emit it.

Other + connectors' `getDeleteFiles` returns empty → `deleteFileNum=0` if their VERBOSE block prints. To be + conservative, the VERBOSE block can be gated to paimon (`getCatalog().getType().equals("paimon")` — + available at `PluginDrivenScanNode.java:244`) so es/jdbc/mc VERBOSE output is byte-unchanged. **Decision: + gate the VERBOSE block to paimon** to minimize blast radius (the 3 paimon assertions are the only + consumers; the `pushdown agg` line stays ungated since it is universally correct and already standard + for every FileScanNode). + - `paimonNativeReadSplits`: connector-dispatched via `appendExplainInfo`, paimon-only by construction. +- **Value correctness (genOut risk).** CI dumped values in genOut.

These are semantic, not just text. See Test Plan for + the comparison-mode reruns that turn genOut into a real check. +- **Real regression vs display gap (per the brief's question).** All 5 are PURE DISPLAY gaps, NOT read-path + regressions: + - #1/#2 count: the data query (`qt_*_count`) returns the correct count via a normal VAGGREGATE; only the + FE `pushdown agg` display line is absent. The count-pushdown OPTIMIZATION still happens BE-side + (`paimon.row_count` is emitted on the range and consumed by `populateRangeParams`); FE just doesn't + render it. (If the optimization were broken, the data result would still be correct — so the explain + line is the only signal; the comparison-mode rerun in Test Plan confirms the BE row-count path.) + - #4/#5 `paimonNativeReadSplits=0/1`: with `force_jni_scanner=true` the reader-selection is correct + (everything JNI); the count is simply not displayed. The `qt_*` reads pass. + - #3 `deleteFileNum`: the deletion vector is correctly applied BE-side (the merge-on-read `qt_*` results + pass); only the VERBOSE accounting line is missing. The deletion file IS threaded to BE + (`paimon.deletion_file.path` → `setDeletionFile`), just not surfaced in FE explain. + Conclusion: NONE of the 5 hides a real read-path regression. They are all the + `plugindriven-explain-override-gap` (no-super) class. +- **oss catalog load risk.** `test_paimon_deletion_vector_oss` uses `oss://` + `oss.endpoint`/`oss.access_key` + (jindo, bundled per `e881247857d` FIX-PAIMON-OSS-JINDO-SELFCONTAINED). The test ran `qt_1..qt_6` before the + explain assertion, so the catalog loaded and the oss reads succeeded — the explain gap is the only failure. +- **FileScanNode helper extraction.** Refactoring lines 151-213 into a protected method changes no behavior + for existing FileScanNode subclasses (Hive/Iceberg/Hudi/Tvf) — it is a pure extract-method.

个的顺序、`equateDistribution` 在这一批内部把分片从"堆得多的 BE"挪到"堆得少的 BE"。而 `nextBe`、`assignedWeightPerBackend` 是**跨批累积的实例字段**（`FederationBackendPolicy.java:84/88`）。所以**同一批分片最终落到哪些 BE 会和现在不同**。 + -

**需要用户签"接受这个负载均衡分配变化"**。 + +2. **正确性不变式要小心**：`needMoreSplit()` 背压要**每批**重新检查（不能攒到一半该停了还继续攒）；末批一定要 flush；批边界不能丢/重分片；`source.close()` 仍在 finally 里吞异常。这些可单测。 + +3. **验证**：碰 fe-core → 两段验（iceberg 连接器不依赖

**理由**：fe-property 已 0 消费者（被 fe-filesystem typed 模型取代），保留=死代码；用户优先清理。**被否**：继续延后到「全部连接器迁完一起清」（fe-property 与 fe-core 两包不同——fe-property 唯一消费者 paimon 已断，可独立删；fe-core 两包仍有 hive/hudi/iceberg 消费者，须留）。 + +##

`DRIVER_CLASS_LOADER_CACHE`/`REGISTERED_DRIVER_KEYS`）；②`PaimonScanPlanProvider.getBackendPaimonOptions`（BE 选项）只解析 URL 不注册。唯一共享=`resolveDriverUrl`。 +- **内容**：**注册副作用留 `PaimonConnector` 不动**；P2-T03 仅把两处 `PaimonCatalogFactory.resolveDriverUrl`（删）改调 `JdbcDriverSupport.resolveDriverUrl`（字节相同）。 +- **理由**：单消费方（FE 注册）→ 下移是为 hive/iceberg 将来服务的投机（Rule 2）；metastore-spi 刻意 SDK/JVM-副作用-free（DV-007 保持 hadoop/fs-free），注入 `DriverManager` 全局变更+活 `URLClassLoader`+`Class.forName` 模糊 api/spi 纯净边界；`DriverShim` 的 loader 身份对 DriverManager 接受是 load-bearing 的，子优先插件 loader 下迁移它有 classloader 风险而零功能收益（CI RCA 记忆 RC-1/3/5 反复证 classloader 危害）。**被否**：方案 B（下移注册）。 +- **影响**：`JdbcDriverSupport` javadoc「注册留待 P2-T03」状态=**已决定不下移**（待 hive/iceberg 真第二消费方时再议）；无新模块改动。 + +## D-014 — P2-T03 采用 spi 的 legacy-faithful validate（CREATE CATALOG 比当前 paimon 更严，故意收敛） +- **日期**：2026-06-18 ｜ **决策者**：用户（AskUserQuestion 选「采用 spi validate（legacy-faithful）」） +- **背景**：P2-T02 的 spi `validate()` 故意比 paimon 手抄 `PaimonCatalogFactory.validate` 严，恢复了真 legacy 规则（手抄版漏掉的）：HMS **case-sensitive** `forbidIf(simple)`/`requireIf(kerberos)`（client principal+keytab）、REST **case-sensitive** `"dlf".equals(token.provider)`（手抄是 equalsIgnoreCase）、DLF 在 **CREATE** 要求 OSS 存储（手抄在 catalog-build 时 `requireOssStorageForDlf`）。P2-T02 只建 spi、无消费方；P2-T03 cutover 是这些规则首次作用于真实 CREATE CATALOG。 +- **内容**：cutover **直接采用** `MetaStoreProviders.bind(props,{}).validate()`，接受 CREATE CATALOG 比当前 paimon 更严（今天通过 paimon 宽松检查的某些 catalog 现在会在 CREATE 被拒）。这是项目 T2「等价=对齐 legacy 非对齐手抄」目标的兑现。 +- **理由**：spi 的更严规则才是权威 legacy（`HMSBaseProperties.buildRules`/`AliyunDLFBaseProperties`/`ParamRules`）；保留手抄宽松行为需 compat shim（更多代码、偏离目标、spi validate 部分闲置）。**被否**：方案 B（compat shim 保 CREATE 字节兼容）。 +- **影响**：行为变更 = 三处更严校验在 CREATE CATALOG 生效；unknown-flavor 错误文案从「Unknown paimon.catalog.type value: X」→ bind 的「No MetaStoreProvider supports...」（两者皆 IAE→DdlException，CREATE 仍失败）；DLF S3-only 拒绝时机 build→CREATE（无 reload 回归：无效 catalog 在新模型下根本无法 CREATE 故不会持久化/reload）。测试：`PaimonConnectorValidatePropertiesTest` 钉新行为（3 tightening RED→GREEN）。 + +## D-013 — Kerberos 中立 facts 类型（AuthType + KerberosAuthSpec）落 fe-kerberos，先于

`fe-filesystem-hdfs` 的 **`HdfsFileSystemProperties`**（`implements FileSystemProperties, BackendStorageProperties`，**不**实现 `HadoopStorageProperties`——BE-only，catalog/Hadoop 路保持现状即 P1-T03 后的 raw

必须套**后端特定**默认值（region/endpoint 推导、S3=50/3000/1000 vs OSS/COS/OBS=100/10000/10000 调优分叉），需 storage providers（ServiceLoader 发现）；而连接器按 D-003 **只见 fe-filesystem-api 接口、不持有 providers**，物理上无法独立完成全程归一。延续 D-003「动态/provider 发现留 fe-core」的精确边界：连接器最轻、归一单点、无漂移。**备选 B（放宽红线让连接器依赖 fe-filesystem-spi/providers 自做端到端）被否**：加重连接器 classpath + 破坏「fe-connector 仅依赖 fe-filesystem-api」红线。 +- **影响**：设计 §2.3（细化边界）；tasks

`fe-common`（低层）反向依赖 fe-connector 子模块=层级倒挂。故必须是**顶层中立叶子**才能被 fe-filesystem-hdfs + fe-common 共用（=满足原始需求「HMS 与 HDFS 都能用」）。**模块名定 `fe-kerberos`**（用户 2026-06-17 确认）。 +- **理由**：现状 kerberos **三处实现**——(1) fe-common `security.authentication.*`（fe-core/HMS/HDFS 用）；(2) fe-filesystem-hdfs **自抄一份** `KerberosHadoopAuthenticator`（为避免依赖 fe-common，一年前拷贝、TGT 刷新可能已漂移）；(3) paimon 手抄 HMS 的 kerberos HiveConf 键 + 回调 `ctx.executeAuthenticated`。改一处要改三处。auth 类 import 干净（仅 JDK/hadoop/log4j/commons/guava + 1 个 trino），fe-common 不依赖 fe-core → 抽取无阻力；`fe-foundation` 现为纯净（零 hadoop）的 `@ConnectorProperty` 叶子，**不应**被 hadoop

走它（paimon-local、纯新增，**不碰** fe-common/fe-filesystem-hdfs 既有路径，符合 D-005）；(b) **P3b = follow-up（本次不做）** = 全量去重（删 fe-filesystem-hdfs 副本、fe-common 重指向 fe-kerberos、统一两个 `HadoopAuthenticator` 接口），与 hive/iceberg 迁移同批——此步改 fe-common + fe-filesystem-hdfs，超出 D-005，故独立。 +- **影响**：设计 §3.5（新增 Kerberos 节）+ 依赖图（加 fe-kerberos 叶子）；tasks 新增 P3；risks 补「kerberos 三处漂移」项。 + +## D-006 — MetaStore 后端「类型」用

`ConnectorMetadata`，读规划与写入**共用它**；写入经共享事务句柄绑定，提交 = `connector.commit(txnHandle)`。我们的目标形状与之**完全一致**。 +- **机制**：把统一入口存的"裸 metadata"升级成 `CatalogStatementTransaction` 共持体（持 memoized metadata + 首次写时懒建的 `ConnectorTransaction`）。现成范本 = `ConnectorRewriteDriver`（co-hold metadata/session + `beginTransaction` + commit/rollback）。 +- **写臂 8 处 getMetadata 改道进同一入口**（均已核实为无状态薄壳的只读用法 + 一次起事务）：`PhysicalPlanTranslator.visitPhysicalConnectorTableSink:660`(INSERT) / `buildPluginRowLevelDmlSink:612`(DELETE/MERGE)、`PluginDrivenInsertExecutor.ensureConnectorSetup:206`、`PluginDrivenExternalTable.resolveWriteTargetHandle:133`（藏在"读"文件里的写专用点）、`BindSink.checkConnectorStaticPartitions:673`/`checkConnectorWritePartitionNames:712`、`IcebergRowLevelDmlTransform.checkPluginMode:112`、`PhysicalIcebergMergeSink.buildInsertPartitionFieldsFromConnector:303`。 +- **两条必守的正确性闸门**（非性能）： + 1. **按连接器保留"起写刷新"**，不一刀切。iceberg 复用语句内共享表（新鲜度靠 `newTransaction()` refresh）；**hive 起写必须保留其在鉴权上下文里当场 `hmsClient.getTable`**（`HiveConnectorTransaction.beginWrite:199/208-211`）——负责 ACID 事务表拒绝 + 权威起始快照。误换成扫描缓存表 = 正确性/授权 bug。 + 2. **身份一致性闸门**：iceberg 接 REST、session=user 时 metadata 烤进 per-user 委派操作（`IcebergConnector.getMetadata:256` `newCatalogBackedOps`）。读/写会话在同一语句本是同一用户，但**须显式断言二者身份指纹相等**再共用，否则理论上"拿 A 的对象执行 B 的写"。 +- **不做的事**：不统一两个 `ConnectorSession`（保留 `setCurrentTransaction` 绑定，更大且无正确性必要）；不引入事务协调器（外部写仍每语句 autocommit，1 StatementContext ≈ 1 外部事务）。 +- **HMS 兄弟**：sibling 入口必须覆盖 **beginTransaction** 路由（`HiveConnectorMetadata:1854`），不仅 getMetadata；键含属主 label，写事务从与读同一个 funnel-memoized 兄弟实例上 mint。 +- **风险**：iceberg session=user 身份错配（首要正确性闸门）；hive 起写刷新丢失；兄弟 downcast；提交/收尾**不得**再调 getMetadata 建第二个实例；maxcompute/jdbc 写壳仅旁证，接入前须确认无状态 + 事务可从共享 metadata mint；scope-map 生命周期须在语句末确定性 close/rollback 未提交事务，且幂等。 + +## 2. 取证结论 B —— "后台线程传递"被证伪，纠正为"读穿 + 修隐患" + +**用户原要求"把统一元数据对象传到后台线程"，取证判定不安全，应反向做。** + +- **为何不安全**：那几个后台加载点填的是**跨语句共享缓存**（活得比语句久）；把每语句实例塞进去、语句末 close → 共享缓存里留**已关闭对象**。后台线程是**全进程复用固定池**（`ExternalMetaCacheMgr` scheduleExecutor），一个查询关掉的资源可能被**无关查询**在同一池线程上误用 → 崩溃/串数据。**明确拒绝 InheritableThreadLocal / 在 worker 上 set**。 +- **正确模型（两分支，也正是 Trino）**： + - **语句派生的异步**（扫描 pump、将来写侧异步）→ **提交时捕获**：复用请求线程上建好的 session（`PluginDrivenScanNode.connectorSession` final 字段，`ConnectorSessionImpl.statementScope` 是 final，脱线程可达）。规则：新异步一律把请求线程 session/scope 传进闭包，**绝不在池 worker 上 `buildConnectorSession()`**（那里 `ConnectContext.get()==null` → 落 NONE）。 + - **真正跨语句的后台缓存加载器**（7 处）→ **一律读穿**：每次临时新建、**显式声明 NONE**（`ConnectorSessionBuilder.withStatementScope(NONE)` 或新增 `buildCrossStatementSession()`），绝不绑定语句实例。7 处 = `PluginDrivenExternalCatalog.listDatabaseNames:295`/`listTableNamesFromRemote:311`、`PluginDrivenExternalTable.initSchema:460`/`getColumnStatistic:1052`/`getChunkSizes:1087`/`fetchRowCount:1153`、`MetadataGenerator.dealPluginDrivenCatalog:1329`。 +- **真实隐患（顺手修）**：`fetchRowCount` **并非**只跑在后台——`AnalysisManager.buildAnalysisJobInfo:415/417` 在 **ANALYZE 语句的执行线程**上直调 `table.fetchRowCount()`，该线程有活的 StatementContext → 会**错误绑定到 ANALYZE 语句的作用域**。今天无害（值是 `Optional`），但一旦实例挂可关闭资源即 use-after-close。→ **对 7 处一律强制 NONE**，把"读穿"从"碰巧落在哪个线程池"变成**强制契约**。 +- **Trino 对齐**：Trino 后台走跨事务缓存（`CachingHiveMetastore`）读穿，不复用事务 metadata；我们**匹配**，并**额外加**一道显式-NONE 守门（因我们的捕获是 thread-driven，Trino 不需要）。 + +## 3. 取证结论 C —— 缓存隔离：确认 list ≠ load，升级为真实安全修复 + +**用户确认 list ≠ load** → "能列举但无权加载"的用户会经缓存命中读到别人授权才见的表结构/快照/分区。**这是真实越权，非纵深防御。** + +- **影响面小**：只涉及 **iceberg 的投影缓存 + fe-core 表结构缓存**；hive/paimon/hudi 无 SUPPORTS_USER_SESSION、无按用户授权轴，**不动**。 +- **两轴切分（对齐 Trino 的切线）**：**只对"不含凭证、授权敏感"的投影按身份分片**（表结构/快照 id/分区规格）；**含凭证的原始表 + FileIO 一律不跨语句缓存**（凭证会过期；身份轴 ≠ 令牌过期轴）。 +- **SPI 原语**：新增连接器无关的 `ConnectorSession.getIdentityShardKey()`（默认取 `getUser()`，源自 Doris 主体非令牌字节 → fe-core 不解析凭证，守铁律）。off-thread loader 也读它，防指纹在请求线程与异步线程间漂移。 +- **iceberg**：把 shard key 放进当前**未门控**的三个投影缓存的 Key——`latestSnapshotCache`/`partitionCache`/`formatCache`（`IcebergConnector` cache 块 ~200-232），仅 `isUserSessionEnabled()` 时填充（否则常量 → 非 session=user 目录字节不变）。关掉残留泄漏（总设计 §8.3⑤：`beginQuerySnapshot` 命中跳过 per-user loadTable）。 +- **fe-core 表结构缓存**（唯一引擎侧泄漏，`SchemaCacheKey` 仅按 nameMapping）：**分层**——(a) 先加 `shouldBypassSchemaCache(SessionContext)`，session=user + 委派凭证下**绕缓存现读**（镜像已安全的库/表名缓存 bypass），最小正确修；(b) 后续若性能需要再把 identityShardKey 织入 Key（触及广泛调用的 `getSchema` 签名 + off-thread loader，更侵入）。 +- **原始表缓存保持 OFF**（`tableCache` 两条件 null 门维持）；语句内复用仍靠 `IcebergStatementScope.sharedTable`（及 P2 后的实例字段）。**P4 恢复的是投影 RPC 的跨语句复用，不恢复 scan 期 loadTable**（那是 P2）。 +- **HMS 异构网关是最尖的洞**：hive 前门（无 SUPPORTS_USER_SESSION → fe-core 名字缓存 bypass 不触发）委派给 session=user 的 iceberg 兄弟时会泄漏；shard key 与 Key 选择须按**有效属主连接器身份**、且经兄弟 getMetadata 路由传播。**必须与 P1 的"键含属主连接器"一并落 + 异构网关 e2e。** +- **防漂移门禁**：加 arch/checkstyle 规则——授权敏感的跨语句缓存的 Key 在 session=user 下**必须**含 `getIdentityShardKey()`，把"加了新缓存忘了分片"从静默泄漏变成构建失败。 +- **Trino 对齐**：切线一致（只缓存无凭证投影、FileIO 每请求现挂）；Trino 的身份分片是 opt-in（impersonation），默认靠缓存之上的 access-control 层，故 **Doris 的"session=user 恒分片"比 Trino 默认更严**（需签字确认这是有意选择）。放置差异：Trino 分在**工厂层**（per-user 缓存实例），我们放**Key 里**（贴合 Doris 扁平有界缓存 + 总设计措辞），同等隔离、靠防漂移门禁补工厂模型的免费防漂移。 +- **待签字/待答**：授权新鲜度（TTL 内远端撤权仍命中，Trino 同性质，可接受但须签字）；manifestCache（默认 OFF，开启则须分片或声明与 session=user 不兼容）。 + +--- + +## 4. 定稿分期（不砍任何一块，只排序 + 独立提交/验证） + +> **为何不一次性全做**：①硬依赖——写入无入口可改道，直到读取键石落地（写严格下游）；②"后台传递"被证伪，非独立第三块，是键石 close 接线的一条正确性约束；③缓存隔离是独立安全工程（未决威胁模型 + 缺 SPI 原语 + 与重构正交），捆进 ~64 处机械改道会给签字施压、且越权回归无法二分定位。约六十多处改道 + 写 + 授权缓存同落刚稳定的性能热路径 = **不可二分的回归面**。 + +| 步 | 内容 | 依赖 | 验证 | +|---|---|---|---| +| **STEP 1 · 读取键石**（原

`ConnectorStatementScope`（`computeIfAbsent(key, loader)` + `NONE` 默认）。**每个连接器天生继承，离线安全退化。** `IcebergStatementScope` 只是 40 行的连接器私有便利包装。所以"新连接器没有统一标准"这个担心其实不成立——标准已发布，缺的只是"更强的强制/便利外壳"。 + +### 4.2 Trino 参照模型：统一靠"引擎自持的每事务生命周期"，不是一个缓存类 +- Trino 每条语句都是一个事务；引擎为每个被访问的 catalog **懒造一个"每事务 `ConnectorMetadata`"实例并 memoize 到事务上**（`IcebergTransactionManager`/`HiveTransactionManager` 内的 per-catalog

`tableMetadataCache`）。`getTableHandle`/`getTableMetadata`/`getColumnHandles`/统计/`beginInsert`/`finishInsert` 都重入**同一个** metadata → 命中缓存 → 远端 `loadTable` 只发一次。 +- **统一的是"共享生命周期"（去重的 span=事务、活满 span 的对象=metadata 都由引擎供给和销毁），"cache-on-metadata" 是自然掉出来的约定**；新连接器实现 `ConnectorMetadata` 即免费获得。 + +### 4.3 为什么 Trino 模型不可直接移植到 Doris +Doris 缺 Trino 的每一个结构前提： +- **无每事务 `ConnectorMetadata`**：Doris 连接器/`*ConnectorMetadata` 是**长期共享单例**（每 catalog 一个、从不按语句造），挂每语句可变缓存会跨语句/跨用户泄漏（正因如此跨查询 `IcebergTableCache` 对 `session=user`/vended 关闭）。 +- `ConnectorSession` **不是稳定 span**（一条语句重建约 26 次，挂它即死）。 +- **DML 事务对象出现得晚、且只在写臂**（`*ConnectorTransaction` 在 beginWrite 才建），无法承载"读+扫描+写成形"整条 span。 +- **唯一活满整条语句、连接器够得到的对象 = fe-core `StatementContext`**，只能经中性 `getStatementScope()` 够到。所以 Doris 必须把 Trino 模型**反过来**：不是"引擎把每事务 metadata 发给连接器"，而是"连接器向上够 fe-core 的 span"。 +- 全盘照搬会撞铁律 A：给 14 个连接器引入每事务 metadata + TransactionManager 生命周期 + 改 planner 每语句取 metadata = 删旧代码期的 fe-core 大净增。 + +**结论：现有 `ConnectorStatementScope` + `getStatementScope()` + `NONE` 已是 Trino 思想在 Doris 铁律下能落地的最高、最可移植高度。** + +### 4.4 高度分级（L0–L3） +| 高度 | 内容 | 现在值不值 | +|---|---|---| +| **L0** | 只把统一**约定写成文**（键格式

`applyFilter/applyProjection/applyLimit/applySnapshot/applyRewriteFileScope/…` 返回**新句柄**逐步精化——这正是 Trino 的 `ConnectorTableHandle`-update 模式。**Trino 不变量③(事实随句柄前向流动、规划期不重解析)Doris 已满足。** +- **语句级宿主已存在**:`StatementContext` 每语句在 `StmtExecutor` 构造时新建、挂到 `ConnectContext`,已托管 MVCC 快照 pin(`StatementContext.snapshots`,一语句一次解析、读写共享)与连接器作用域,随语句 GC。`ConnectorStatementScope`(挂在它上的 `ConcurrentHashMap` memo 竞技场)+ iceberg 的 `IcebergStatementScope` 已用它做到"一语句一张表只加载一次"。 +- **但作用域只是"半成品"**:它是**无类型的 String→Object 竞技场**,不是**有类型的每语句 `ConnectorMetadata`**;**规划器不经它取表**(规划器走的是跨语句的 `ExternalCatalog` 元数据缓存);只有 iceberg 一个连接器手写键去消费它。也就是说"读规划的取表路径"和"每语句加载归属者"**今天还不是同一条缝**——而 Trino 把它们合成了一条。 + +### 1.4 事务模型(现状割裂) + +- **外部无统一事务管理器**:每个 `ExternalCatalog` 自持一个 `TransactionManager`;plugin 目录一律用 `PluginDrivenTransactionManager`,把 commit/rollback/close 委派给**连接器在 `beginTransaction` 才晚建**的 `ConnectorTransaction`(`session.allocateTransactionId()`),绑到 session、`onComplete` 提交/`onFail` 回滚。 +- **`ConnectorTransaction` 是糟糕的 span 宿主**:出生太晚(仅 beginWrite)、只在写臂、读/规划期根本看不见。 +- **内部 OLAP 是另一条路**:`GlobalTransactionMgr` + 每连接 `TransactionEntry`;`GlobalExternalTransactionInfoMgr` 只是个 id→Transaction 的注册表(供 BE→FE RPC 查),**不是协调器**。内外无共享抽象。 +- **外部写实际上是"每语句 autocommit"**:`ConnectorTransaction` 在一条语句内建、在该语句 `onComplete` 提交 → **一个 `StatementContext` ≈ 一个外部事务**。这让 `StatementContext` 成为 span 宿主是**自然且正确**的。 + +--- + +## 2. Trino 为什么优雅（四条不变量）+ 两处弱点 + +经源码核实(`trinodb/trino` master,下引类名/行号来自该轮 web recon): + +**四条不变量:** +1. **事务 = 元数据的身份与生命周期单位**。无显式 BEGIN 的语句跑在 autocommit 事务里;每个被触达的 catalog,`TransactionManager` 懒建并 memoize **一个** `CatalogMetadata`(`activeCatalogs` map,`CatalogHandle` 为键);其内 `CatalogTransaction` 用 `@GuardedBy(this)` 字段 memoize **恰好一个** `ConnectorMetadata`(`connector.getMetadata(session, txnHandle)` 只调一次)。commit/rollback → `connector.commit/rollback` → 事务移除。**无人工失效、无跨语句泄漏。** +2. **单一漏斗、单一实例**。所有元数据调用走 `Session → MetadataManager → TransactionManager → CatalogMetadata → CatalogTransaction`。**memoize 发生在管道层,不在连接器里** → 一语句一实例由**引擎**保证,与连接器自觉性无关。 +3. **事实随句柄前向流动、不靠重载**。`getTableHandle` 一次解析,快照 id/schema/分区 spec 装进不可变 `ConnectorTableHandle`,穿过 analyze/optimize/execute 直到 `beginInsert/beginMerge`。规划期从不重解析。 +4. **身份是事务级的 → 按用户隔离白拿**。`ConnectorMetadata` 用 `session.getIdentity()` 构建;`ConnectorSecurityContext = txnHandle+identity+queryId`;事务是每 session 的,故 metadata **从不跨用户共享**——隔离是事务模型的副产品。 + +**两处弱点(Doris 应超越):** +- **弱点 A**:每事务 `ConnectorMetadata` 被 memoize 了,但**加载到的 Table 对象没有**(iceberg)。`IcebergMetadata` 只缓存统计;`getTableHandle/getTableMetadata/getTableProperties` 各自重调 `catalog.loadTable()`,把去重下推到**每事务 `TrinoCatalog` 上有界可淘汰的** `tableMetadataCache`(maxSize ~1000)。**多表语句会淘汰重载 → "一语句一次加载"是软的、非结构性的**(直接坐实了"一条语句 loadTable 3–4 次靠下层缓存兜")。 +- **弱点 B**:core `CatalogTransaction` 已保证 `getMetadata` 只调一次,Hive 连接器却**又在 `HiveTransactionManager.MemoizedMetadata` 里重复实现一遍**每事务 memo。冗余耦合。 + +--- + +## 3. 目标架构（Doris 版：对齐 Trino 的不变量，并针对性超越其弱点） + +### 3.1 核心：引擎自持的"每语句/每事务 metadata 实例"，memoize 在管道层 + +把今天"每次调用新建即弃"的 `ConnectorMetadata`,改成**每(语句, catalog)一个、由引擎懒建并 memoize、语句/事务结束时确定性销毁**。 + +- **宿主 = `StatementContext`**(外部写=每语句 autocommit,一 `StatementContext` ≈ 一外部事务;宿主已在,已托管 MVCC pin 与作用域,已有正确 GC/reset)。 +- **管道层单一漏斗**:在语句 span 上加 `ConnectorMetadata getOrCreateMetadata(catalogId)`,懒建、memoize、语句内所有 seam 复用同一实例——**对应 Trino 不变量②,且 memo 在引擎侧,连接器零自觉性要求**(直接规避 Trino 弱点 B:连接器不再各自手写 memo)。 +- **off-thread 可达**:实例引用像作用域一样在 `ConnectorSession` **构造期捕获**,异步 scan pump / 缓存 loader 无 thread-local 也够得到。 +- **确定性销毁**:`StatementContext.close()` 逐 catalog `metadata.close()`(对齐 Trino 的 commit/rollback 即销毁;比今天纯靠 GC 更干净)。 + +因为 `ConnectorMetadata` 今天已是"无根的临时外壳"(designNotes 原话:"除了缓存,没有任何东西把它钉在每调用"),且句柄已满足不变量③,这一步在结构上**主要是引擎侧改道 + 把缓存归属从单例挪到实例**,SPI 方法签名基本不用动(方法本就吃 `(session, handle)`)。 + +### 3.2 超越点①：结构性的"一语句一次加载"(打败 Trino 弱点 A) + +把**每语句工作集**(一次加载的 raw Table、扫描→写的删除清单桥、列句柄)从"连接器单例上的缓存 / 无类型 String→Object 作用域",**上移成每语句 metadata 实例上的字段**。 + +- iceberg 的 `IcebergStatementScope.sharedTable`/`rewritableDeleteSupply` 从"外挂 side-car"变成"实例的字段" → **加载一次成为硬的结构性质**(实例在,表就在;不是有界可淘汰缓存)。**这比 Trino 的 iceberg 更硬。** +- paimon 的胖句柄 `PaimonTableHandle.paimonTable` 溶进实例字段,句柄回归纯坐标(iceberg 已做过同款)。 + +### 3.3 超越点②：两级缓存 —— 每语句工作集 之上/之下

caching 层),**按身份分片** | 跨语句复用;**值敏感处把 identity 放进 key** | Trino 的 `CachingHiveMetastore` / `TrinoCatalog` 缓存 | + +关键洞察(对齐 Trino 不变量④,并补 Trino 未系统化之处): + +- **正确性坍缩成一条性质**:每语句实例**天然单用户**(一语句一用户),故其内部一切缓存**永不跨用户** → 今天散落的 ~6 处门禁(`SUPPORTS_USER_SESSION` 分支、`shouldBypassTableNameCache/DbNameCache` 两钩子、`IcebergTableCache` 置 null、`IcebergCommentCache` 门禁、`IcebergStatementScope` side-car)**收敛成"实例是每语句/单用户"这一条结构性质**,删掉一整类"新加了个缓存忘了 gate"的 bug。 +- **性能补窟窿在下层**:今天 session=user/凭证目录下,跨语句缓存被**整个关掉**(`IcebergTableCache=null` 等),每条语句都为每张表多付 1 次 `loadTable` + 1–2 次 list RPC。**把下层跨语句缓存改成按身份分片(identity 进 key)** → 按用户的跨语句复用安全恢复。**这才是按用户场景真正的性能收益所在。** + +### 3.4 超越点③：把写事务并进同一个 span + +- `beginWrite` 从"重新 `loadTable`"改成"**从每语句实例取已解析的表**"(保留 openTransaction 的 refresh 兜新鲜 OCC 基底)。 +- `ConnectorTransaction` 不再是"晚建 + 绑 session"的孤儿,而是**由每语句 metadata 实例/span 持有**;commit/rollback 由 span 在语句末驱动。写路径两个 session 的割裂被收编。对齐 Trino"metadata 即事务、写方法吃句柄、commit=connector.commit(txnHandle)"。 + +### 3.5 超越点④(远期/可选)：统一内外事务协调器 + +- Trino 只有外部连接器,没有"内部表"二元性;Doris 有 `GlobalTransactionMgr`(OLAP) 与 `PluginDrivenTransactionManager`(外部)两套。**把二者统一到一个事务协调面**,让外部写能参与多语句 `BEGIN..COMMIT`(span 挂 `ConnectContext`、`StatementContext` 持每语句视图,即"两级 span")——这是 Doris **特有**的自洽升级(不是"打败 Trino",是补 Doris 的割裂)。**最深、风险最高、对"达到 Trino 平价"非必需**,列为远期。 + +### 3.6 附带清理(与主线解耦，可先落) + +- **`ConnectorSession` 变廉价 + 不可变**:每语句 memoize 一次 var-map 快照,消灭 ~26 次 `VariableMgr.toMap` 反射 dump;把唯一可变字段(transaction 槽)移到

`getMetadata / getScanPlanProvider / getWritePlanProvider / beginTransaction`,fe-core 从不跨调用持有 metadata 引用(唯一例外是写执行器的 `writeOps` 字段)→ 改道是机械但可枚举的工作。 + +### 4.2 风险(诚实列出) +1. **回归面**:~40 处读热路 seam 改道,踩在刚稳定的读热缝上(PERF 系列)。→ 缓解:分期、每期加"加载计数守门"回归。 +2. **确定性销毁 vs off-thread**:实例不能在异步 scan pump 还在用时提前 close。→ 缓解:沿用作用域的"随语句 GC + 不在 close() 里清工作集"纪律,只在确证无 off-thread 引用处做确定性 close。 +3. **异步缓存 loader 无

The aliases *are* mechanically dropped from the per-FS Configuration — **but the impact does not occur**: the authenticator's first `doAs` calls `UserGroupInformation.setConfiguration(kerberosConf)` (JVM-global), so SASL/Kerberos negotiation is gated by the global UGI security state + the doAs UGI, **not** by the per-FileSystem Configuration's `hadoop.security.authentication`. Kerberized HDFS still opens; the missing per-FS marker is cosmetic/defensive. → **C2's required remediation is just the XML-resource fix** (have `HdfsFileSystemProperties` expose its already-XML-loaded backend map to the FE Hadoop-config path); the kerberos-alias UT proposed in wave 1 would assert a non-load-bearing property. + +--- + +## Appendix: refuted findings + +| id | dim | title | why refuted | +|----|-----|-------|-------------| +| R2 (table) | ddl | DROP TABLE of non-existent table loses MySQL errno 1109 | The legacy PRODUCTION drop path was base `ExternalCatalog.dropTable`, which short-circuits on local-cache miss and throws the **identical** generic `DdlException("Failed to get table: ...")` — byte-identical to the bridge. The `ERR_UNKNOWN_TABLE` arm in `performDropTable:291` was never reached for a cache-absent table; even in the only reachable case it is swallowed by `dropTableImpl`'s `catch(Exception)` re-wrap (drops the errno).

create Iceberg v3 table with reserved row lineage column: _row_id"；branch 静默建成 v3 表且含同名用户列 `_row_id`，读路径又对 v3 表追加隐藏行级血缘同名列（IcebergConnectorMetadata:377-390），schema 冲突/歧义，CREATE 时零报错。 +- 建议修法方向：在活路径（PluginDrivenExternalCatalog.createTable 或中立 converter）复刻「catalog 级 format-version 解析 + v3 保留列校验」，令 FE 校验口径与连接器建表口径一致；或让连接器侧在 buildSchema 阶段拒绝保留列名。 +- 文档跟踪：**新发现**。文档只覆盖连接器读侧 v3 血缘追加与已修的 P6.1「format-version 恒 2」连接器 pin（#63825），均未覆盖此 FE CREATE 时校验缺口。 + +### F2 / F15 — hms-flavor iceberg 的 opt-in test_connection 元存储探测静默 no-op〔medium｜新发现（与文档冲突）〕 +- 位置：`fe/fe-core/.../datasource/connectivity/CatalogConnectivityTestCoordinator.java:284`（IcebergHMSMetaStoreProperties 臂）＋组件 `IcebergHMSConnectivityTester.java`（F15） +- master 行为：`CREATE CATALOG ...

IcebergConnector.testConnection 仅在 `TYPE_REST.equalsIgnoreCase(catalogType)`（:218，javadoc "Metastore (REST only)"）内探测元存储；hms flavor 无任何元存储探测；probeStorage 需用户显式给 s3.access_key+s3.endpoint 方运行；preCreateValidation 仅 jdbc。非 HMS-DLA lane（DLA 是 hive catalog→HiveHMSProperties→另一条臂）。 +- failureScenario：上述 CREATE 在 branch 上零探测直接成功，坏 metastore URI 只在首次查询/SHOW DATABASES 才暴露；用户显式请求的 opt-in 校验静默变空操作。 +- 建议修法方向：在 IcebergConnector.testConnection 为 hms flavor 补 HMS thrift 探测（或在 preCreateValidation 注册对应 BE test）。 +- 文档跟踪：**新发现，且与文档冲突**（removal-plan §4 称 test_connection 已 FULLY 承接，代码证否，见

PluginDrivenSysExternalTable（PluginDrivenSysTable extends NativeSysTable），doRun:156 只 unwrap IcebergSysExternalTable（post-flip 恒 false），sys 表原样进 Env.getDdlStmt：header 用 `tbl$snapshots`、列用 sys 元数据列（getBaseSchema），PLUGIN_EXTERNAL_TABLE 臂（Env.java:4915-4962）只对 sort/LOCATION/PROPERTIES unwrap 到源、且对 sys 表抑制 PARTITION BY（:4944）。注意：validate()（:121-125）**有** PluginDrivenSysExternalTable unwrap 臂（权限正确），唯 doRun 漏，是不对称遗漏。此为 iceberg 采纳了 paimon 的 sys 表约定（master paimon 亦不在 command 级 unwrap），但对 iceberg 是未标注的行为变更。 +- failureScenario：`SHOW CREATE TABLE db.tbl$snapshots` 输出的表名、列清单变了，PARTITION BY 消失；任何 diff SHOW CREATE 的用户/工具会看到差异。仅输出变化，无 crash，权限不受影响。 +- 建议修法方向：doRun 补 `instanceof PluginDrivenSysExternalTable → getSourceTable()` 臂（与 validate 对称）。 +- 文档跟踪：**与文档冲突**（D-066 称 SHOW CREATE 输出已由 Env.getDdlStmt+UserAuthentication 全处理，实为 recon 误框，漏了 CREATE-header/columns，见 §四）。 + +### F5 — PlanNode 的 IcebergScanNode import（支撑 949/965 两臂）〔info｜已跟踪〕 +- 位置：`fe/fe-core/.../planner/PlanNode.java:39`

SUPPORTS_NESTED_COLUMN_PRUNE:511，SlotTypeReplacer 重写 field id）。 +- 缺口：PluginDrivenScanNode.getNodeExplainString（:292-399）整体替换 FileScanNode body，从不调用 super/printNestedColumns（FIX-E 只重发 inputSplitNum/partition/backend-detail/pushdown-agg）；IcebergScanPlanProvider.appendExplainInfo 只发 manifest-cache 与 icebergPredicatePushdown。整个「nested columns:」块（含 pruned type、all access paths、field-id

enableStrictConsistencyDml=true 两侧等价；仅 `enable_strict_consistency_dml=false` 时 master 允许剪枝、branch 禁止——纯计划/性能回退（更多 exchange），非默认 session 配置，结果正确。**行为 delta 真实**，但已作为 **DV-013** 登记为「非回归、接受」并留 deferred

位置：同 F9（getComment(boolean) override）→`PluginDrivenExternalTable.getComment(boolean)`（:625-643） +- 缺口：孪生 override 存在且做转义，但继承 F9 根缺陷（底层 comment 恒 ""）。次要潜在分歧：孪生转义单引号（`replace("'","\\'")`），legacy SqlUtils.escapeQuota 转义双引号——字符不同；当前因值恒空而 moot（`"".replace(...)`=`""`，两侧一致）。第一票 REFUTE（孪生存在、转义分歧不可达）但 2 票 UPHOLD（底层缺陷真实）。承载性修法在连接器侧 getTableComment（同 F9）。 +- 文档跟踪：**新发现**。 + +### F11 —

false；StatementContext.registerExternalTableForPreload（:503）据此门控，flipped iceberg 永不注册为预热候选。 +- failureScenario：混合内部 OLAP + flipped iceberg 且 `enable_preload_external_metadata=1` 的查询：master 在取内部读锁前预热 iceberg schema/partition，branch 变为 binding 期同步加载（持锁更久、慢 metastore 上延迟更高）。纯性能/锁延迟回退，无正确性影响；且 opt-in（session var 默认 false）。 +- 建议修法方向：在 PluginDrivenExternalTable 放开 iceberg（或经 ConnectorCapability

nothing 并落回 SDK 默认链（in-code "Documented GAP"）。 +- failureScenario：glue/s3tables/rest-sigv4 catalog 无静态 AK/SK、无 role、`s3.credentials_provider_type=ANONYMOUS`（或强制 WEB_IDENTITY 等）：master pin 到该

一致、外表不可达，非回归）（`show-metadata`/`sweep-instanceof`，confirmed）。 + +--- + +## 七、残留旧逻辑 / fallback 风险（回答第 16 个问题） + +**核心结论：翻闸路径下不存在"仍走旧逻辑或回退到旧逻辑"的活路径——legacy Iceberg 类（IcebergExternalCatalog/Database/Table/SysExternalTable、IcebergTransaction、legacy planner sink、IcebergScanNode、IcebergMetadataOps、IcebergExternalCatalogFactory）对生产 Iceberg 目录全部成死码。** 但存在以下需注意的结构性事实与潜在陷阱： + +1. **死码 instanceof 臂遍布 live dispatch，正确性靠平行 PluginDriven 臂全覆盖**（`sweep-instanceof`/`sweep-capability-gating`，confirmed，info）。翻闸后运行时类型是 `PluginDrivenExternalCatalog`/`PluginDrivenMvccExternalTable`/`PluginDrivenSysExternalTable`，所有 `instanceof IcebergExternalTable/Catalog` 求值为 false。每处验证均有能力门控或 instanceof-PluginDriven 平行臂提供等价行为。**风险**：正确性"逐点"依赖人工写的能力孪生臂——任一缺孪生臂即静默回归。H-10（嵌套裁剪）正是这种模式的一次失败实证（`LogicalFileScan` PluginDriven 臂硬编码 false，无能力孪生）。**建议**：全量审计每个 legacy iceberg 臂是否有能力孪生（这是上线前的唯一保证）。 + +2. **GSON 持久化兼容**（`sweep-persistence`，confirmed）：旧镜像的 8 个 iceberg catalog flavor 标签、IcebergExternalDatabase、IcebergExternalTable 标签经 `registerCompatibleSubtype`（仅读侧 labelToSubtype）迁移到 PluginDriven 类型；无任何 legacy iceberg 类留在写侧 subtypeToLabel，**不可能被重新序列化**。升级老集群安全；降级（新镜像→老 FE）不支持（符合 Doris 惯例）。 + +3. **buildDbForInit 'case ICEBERG' 死分支**（`sweep-persistence`，confirmed，low）：`ExternalCatalog.java:959-960` 仍构造 legacy IcebergExternalDatabase，但翻闸下不可达（PluginDriven 覆写强制 PLUGIN logType）。**潜在陷阱**：IcebergExternalDatabase 仅 registerCompatibleSubtype（读侧），若未来误复活该分支，序列化会 fail-loud。建议全量翻闸时删除。 + +4. **meta-cache route resolver 仍按 instanceof IcebergExternalCatalog**（`sweep-persistence`，confirmed，low）：翻闸 iceberg 落到 ENGINE_DEFAULT 而非 ENGINE_ICEBERG。因 init 与 invalidate 共用 resolver 且连接器自管缓存，内部一致无 stale-cache bug——**但这正是 H-5/H-6 的根因**（连接器自有缓存永远摸不到）。建议全量翻闸时改为能力/插件检查。 + +5. **builtin-classpath（test/dev）模式的 flavor 碰撞**（`catalog-types`，partial，info）：仅当 paimon+iceberg metastore provider 共享一个 loader（test/builtin 模式）时 `bindForType('hms')` first-match 不确定。**非生产翻闸路径**（生产每插件独立目录 loader）。 + +6. **ConnectorCapability dead-by-name 假门控**（confirmed，info）：声明 SUPPORTS_INSERT/TIME_TRAVEL 等无运行时效果；真门控是 boolean SPI。**陷阱**：未来贡献者按枚举声明能力却忘记 boolean（或反之）→ 静默能力不匹配。建议合并两套能力面或删死枚举值。 + +7. **legacy IcebergDeleteCommand 类部分可达**（`sweep-instanceof`，confirmed 修正）：仅 `run()`/`getExplainPlan()` 硬守护方法不可达；`completeQueryPlan(ExternalTable)` 经 synthesize() 仍被 PluginDriven 复用（接受中立 ExternalTable）。非回退到旧逻辑，是中立类复用。 + +**总判**：无活的旧逻辑回退路径；最大 fallback 风险是 (a) 能力孪生臂的"逐点覆盖"脆弱性（已实证一次失败 H-10），(b) 连接器自有缓存因 route resolver 走 ENGINE_DEFAULT 而被 REFRESH CATALOG / 存储过程失效漏清（H-5/H-6）。 + +--- + +## 八、真回归 vs 内生缺陷分类汇总 + +**真回归（vs master 原逻辑，isRegression=true）**——绝大多数发现属此类，因迁移改变了曾正确的行为：B-1、B-2、H-1~H-11、M-1~M-11、L-1~L-25 大部分。这些是上线前的主要修复目标。 + +**内生缺陷 / 设计问题（与原逻辑无关，isRegression=false）**： +- ConnectorCapability 14 dead-by-name + 两套能力面不同步（SPI 新架构缺陷，master 无对应物，isRealBug=false 但 design medium）。 +- `ExternalMetaCacheInvalidator` 对 plugin catalog 恒路由 ENGINE_DEFAULT、摸不到连接器缓存（SPI 设计缺口，high——这是 H-5/H-6 的根因，无直接 legacy 对应但导致回归行为）。 +- read-path static+vended MERGE 设计缝（当前被 invariant 中和，info）。 +- begin-once 守护无并发测试覆盖（测试质量，low）。 +- runInAuthScope context==null 跳过失效（仅测试可达，info）。 +- 错误契约/errno 设计观察（多为 parity 或改善，info）。 + +--- + +## 九、建议的下一步动作（按优先级） + +**P0 — 翻闸前必须关闭（硬阻塞）** +1. 修 B-1：`IcebergWritePlanProvider.buildHadoopConfig` 改用 BE 规范 `AWS_*`（`getBackendStorageProperties`），对齐 scan 与 BE 契约。 +2. 修 B-2 / H-11 / M-10：在 `IcebergConnectorMetadata` 实现 `listPartitions`（携 per-partition last-modified + RANGE 语义），协调通用 MVCC 模型 RANGE-vs-LIST 分区名，恢复 Iceberg MTMV 分区增量刷新与 SHOW PARTITIONS。 + +**P1 — 翻闸前强烈建议关闭（high，否则上线即静默退化）** +3. 修 H-1：写侧叠加 vended credentials（随 B-1 key-form 一并）。 +4. 修 H-2：getScan/Write/ProcedureProvider 改用携 externalCatalogName 的 5-arg ops ctor。 +5. 修 H-3：Iceberg MetaStoreProperties 子类覆写 `initExecutionAuthenticator`（镜像 Paimon）。 +6. 修 H-4：`IcebergConnectorMetadata` 覆写 `getTableStatistics`（镜像 Paimon），恢复表级行数。 +7. 修 H-5 + H-6（共同根因）：让 SPI invalidator / `onRefreshCache` 能触达连接器自有缓存（route resolver 加 PluginDriven 臂调 `getConnector().invalidate*`，或委托 `refreshTableInternal`）；且 `IcebergProcedureOps` 传 LOCAL 名。 +8. 修 H-7：非数字 FOR VERSION AS OF 兼试 branch+tag。 +9. 修 H-8：`PluginDrivenExternalTable.initSchema` 加 isView 分支构建视图列 schema。 +10. 修 H-9：rewrite_data_files WHERE 下推改用 scan-mode 谓词矩阵。 +11. 修 H-10：新增 nested-prune ConnectorCapability，Iceberg 声明之。 + +**P2 — 翻闸窗口或紧随其后（medium）** +12. M-1/M-5（HDFS warehouse 推导、broker 写地址）、M-2/M-3/M-4（split 权重、batch 流式、Top-N field-id 字典）、M-6（复杂 modify 文案 + e2e）、M-7（DLF CREATE TABLE 守护）、M-8（SHOW CREATE DATABASE LOCATION）、M-9（dropDb REMOTE 名）、M-11（DROP DATABASE FORCE 容忍）。 + +**P3 — 工程化保障（贯穿全程）** +13. **全量审计 legacy iceberg instanceof 臂的能力孪生覆盖**（针对第七节风险 1，H-10 是已实证失败样本）——这是防止"逐点静默回归"的唯一保证。 +14. 修一批 low 真回归中影响测试/正确性的：L-12（PROPERTIES 顺序非确定，一行 LinkedHashMap）、L-21/L-22（schema-change 文案与 e2e）、`gap` DECIMAL→STRING toPlainString（一行修，窄但真错误结果）、L-6/L-12 等破坏 .out 的文案/顺序。 +15. 清理设计债：删/接线 ConnectorCapability 14 dead-by-name、删 buildDbForInit case ICEBERG 死分支、统一两套能力面、为 begin-once 守护补并发测试。 +16. **在 docker/真集群跑全套 flip-gated e2e**：DV/V3、MTMV、time-travel branch/tag、vended-credentials 写、Kerberized HDFS、rewrite_data_files——这些发现大多 flip-gated 未实跑，必须 e2e 验证后方可二签翻闸。 + +**复核 partial 结论**：上线前应人工复核所有标"部分成立/存疑"的发现（L-8 认证机制、L-16 paimon vs jdbc/es、L-19 view DML 回归框架、L-21/L-22 机制描述、L-24/L-25 dormant/refute、M-7 DLF 4/5 仍 fail-loud、bindForType 隔离机制），避免按被证伪的机制描述误修。 diff --git a/plan-doc/reviews/cache-invalidation-cleanroom-review-2026-07-10.md b/plan-doc/reviews/cache-invalidation-cleanroom-review-2026-07-10.md new file mode 100644 index 00000000000000..f5bb21c9487909 --- /dev/null +++ b/plan-doc/reviews/cache-invalidation-cleanroom-review-2026-07-10.md @@ -0,0 +1,83 @@ +# Cache-invalidation fixes — clean-room adversarial review (2026-07-10) + +> Adversarial review of the three connector-cache invalidation fixes landed this round +> (`3b66982fedf` D1 fe-core hook, `7b8fed012be` D1b paimon memo, `982db925659` D2 per-partition keying). +> Run `wf_fe6ddef4-777`: 4 blind dimension readers (D1 / D1b / D2 / completeness) → each finding +> adversarially verified by 3 independent lenses (correctness / concurrency-or-parity / does-it-reproduce), +> confirmed at ≥2/3.

Followers/ +observers replay via `ExternalCatalog.replayDropTable`/`replayCreateTable`/`replayDropDb` (the PluginDriven +branch, metadataOps==null) which touch only the FE name cache — never `connector.invalidate*`. So a +follower that had queried paimon/iceberg `d.t` keeps its `latestSnapshotCache[(d,t)]` pinned to the dropped +table's snapshot until the 24h access-TTL. +- **Precedent (this is normally done):** `RefreshManager.replayRefreshTable → refreshTableInternal:254-257` + DOES call `connector.invalidateTable` on replay; and `PluginDrivenExternalCatalog` already added a + `replayTruncateTable` override that routes through `refreshTableInternal` for exactly this reason. +- **Fix:** override `replayDropTable`/`replayCreateTable`/`replayDropDb` in `PluginDrivenExternalCatalog` + (or the shared replay seam) to also call `connector.invalidateTable`/`invalidateDb` after the base + bookkeeping, mirroring `replayTruncateTable`. Needs the remote names on the replay path (resolve like the + coordinator does, or persist them in the log). + +### R2 — iceberg/paimon do not override `invalidateDb` → DROP DATABASE + REFRESH DATABASE are no-ops (MEDIUM, LIVE) [= confirmed #2 + #4, same root] +Only `HiveConnector` overrides `invalidateDb`; `IcebergConnector`/`PaimonConnector` inherit the SPI no-op +default (`Connector.java:324`). So: +- The new `dropDb → connector.invalidateDb(d)` hook (D1) is INERT for iceberg/paimon (the dropDb comment's + "drops every table in this db" is false for them). `DROP DATABASE d FORCE` cascades table drops INSIDE the + connector, bypassing per-table `invalidateTable`, so the cascaded tables' `latestSnapshotCache`/ + `PaimonSchemaAtMemo` entries survive. +- **Pre-existing (independent of this round):** `RefreshManager.refreshDbInternal:126 → invalidateDb` — so + `REFRESH DATABASE d` on iceberg/paimon has ALWAYS been a silent no-op for their snapshot/schema caches. +- Also: hive's `forEachBuiltSibling(sibling.invalidateDb)` is a no-op against the iceberg/hudi siblings + post-flip for the same reason. +- **Fix:** add `invalidateDb(db)` overrides to `IcebergConnector` (db-scoped removeIf over + `latestSnapshotCache` keys whose namespace==db) and `PaimonConnector` (`latestSnapshotCache` + + `PaimonSchemaAtMemo`, db-scoped). Requires a db-scoped invalidate on `IcebergLatestSnapshotCache` / + `PaimonLatestSnapshotCache` / `PaimonSchemaAtMemo` (mirror the existing per-table `matches`). Fixes the + D1 dropDb hook AND the pre-existing REFRESH DATABASE gap in one go. + +### R3 — `getPartitions` raw `put` bypasses the invalidateGeneration guard (MEDIUM, DORMANT) +The rewritten `getPartitions` uses `partitionsCache.put(...)` directly (`CachingHmsClient.java:182`), which +has no generation check. The pre-commit code used `partitionsCache.get(key, loader)` → `getWithManualLoad`, +which captures `invalidateGeneration` before the load and drops the put if a `flush` raced it +(`MetaCacheEntry.java:240-256`). So a `REFRESH TABLE` (`flush`) racing an in-flight cold-cache fetch now +re-caches the pre-refresh partitions, which survive until TTL/next REFRESH. `getTable`/`listPartitionNames`/ +`getTableColumnStatistics` still use the guarded path — only `getPartitions` lost it. +- Currently dormant (hive not flipped; `flush` not yet wired to REFRESH for a live hms catalog). +- **Fix (keep bulk RPC + per-partition keying + divergence-safety):** add a generation-guarded put to the + connector copy of `MetaCacheEntry` — `long invalidationGeneration()` + `putIfNotInvalidatedSince(gen, key, + value)` (put under the key's stripe lock, then `removeLoadedValue` if the generation moved). In + `getPartitions`, capture the generation BEFORE the delegate RPC, then guard each per-partition put with it; + keep adding the delegate results to the result list directly (preserves the misparse→never-drop safety). + This is an ADDITIVE framework method (no behavior/byte change for paimon/iceberg; same Caffeine version). + +### R4 — RENAME TABLE never invalidates the connector cache (weak 1/3, but strong reasoning; LIVE) +`renameTable → afterExternalRename` (`:~649/1007`) runs unregister+resetMetaCacheNames+constraint+editlog and +NEVER calls `connector.invalidate*`, and does NOT route through `refreshTableInternal` (unlike truncate / +column-ALTER). So an iceberg/paimon atomic table-swap (`RENAME t→t_arch; RENAME t_new→t`) leaves the stale +`latestSnapshotCache[(db,t)]` pinned → the recreated `t` reads the OLD snapshot. Same drop+recreate class +D1 targets; the design doc even cites Trino's `renameTable` self-invalidation as the parity model, then +FIX 1 hooks only dropTable/createTable/dropDb. **Fix:** invalidate the source (and target) name's connector +cache in the rename path (source on the coordinator + replay; and `replayRenameTable` for followers).

`CachingHmsClient`/`HiveFileListingCache`),keyed `(project,db,table)`,`REFRESH` 失效——**不**在 fe-core 加二级缓存(违背 connector-owned 方向)。若延后,须在 deviations-log 正式登记(CACHE-P1 从未登记)。 + +### M5 — P6-3:iceberg `computeRowCount` 丢 equality-delete gate(仍然;iceberg-on-HMS 新激活) + +- **现证据**:`IcebergConnectorMetadata.computeRowCount:631-646` 只读 `total-records`、`total-position-deletes`,无条件返回 `totalRecords - positionDeletes`,无 equality-delete gate(类只声明 `TOTAL_RECORDS`/`TOTAL_POSITION_DELETES`)。其 javadoc(`:624-629`)与单测 `equalityDeletesDoNotGateTableStatistics:195-210` 断言"legacy 不 gate"——**此前提为假**:legacy `IcebergUtils.getIcebergRowCount:1202`→`getCountFromSummary`,`:231-233` `if (!equalityDeletes.equals("0")) return UNKNOWN_ROW_COUNT`。COUNT(*) 下推副本 `IcebergScanPlanProvider.getCountFromSummary:1572-1574` **保留**了 gate→**不对称**:有 equality-delete 时 COUNT(*) 正确退让,但 `getTableStatistics` 报膨胀行数→误导 CBO。 +- **翻闸影响**:type=iceberg 自 P6 已在 SPI(故"仍然");但翻闸让 **iceberg-on-HMS** 也走 `computeRowCount`(legacy HMS 路 `HMSExternalTable:547` 走带 gate 的 `getIcebergRowCount`)→对 iceberg-on-HMS 是**新激活**。非登记偏差。 +- **解决方案**:加 `TOTAL_EQUALITY_DELETES` 常量,`computeRowCount` 在减法前 `null || !="0"→返回 -1(UNKNOWN)`,复现 legacy;订正 javadoc + 重写把回归锁死的单测(应断言 UNKNOWN)。 + +### M6 — P6-4:iceberg s3tables 无显式凭证即硬失败(仍然) + +- **现证据**:`IcebergConnector.createS3TablesCatalog:735-739` `if (!chosenS3.isPresent()) throw ...`;`chosenS3` 来自 `S3FileSystemProvider.supports:64-74`,要求 `hasCredential(AK/SK||roleARN||credentials_provider_type) && hasLocation`(除非 explicit-S3)。EC2 instance-profile s3tables 目录(仅 `s3.region`+warehouse ARN,无静态凭证/无 marker)→`supports()=false`→无 S3 storage→`chosenS3` 空→**建表首访抛**。 +- **对比 legacy**:`IcebergS3TablesMetaStoreProperties` 直接 `S3Properties.of(origProps)`(无凭证 gate)+ `createAwsCredentialsProvider(...,false)`→无静态凭证时返回 `DefaultCredentialsProvider`(instance-profile 默认链)→region+warehouse-only 可用。现 `supports()` 比报告**更松**(接受 `credentials_provider_type`),故可用 `s3.credentials_provider_type` 绕过,但纯默认链场景仍硬失败。**回归**,fail-loud,非登记。 +- **解决方案**:`createS3TablesCatalog` 在 `chosenS3` 空但能从原始 props 解析出 region 时(复用 M7 拓宽的别名),用 `DefaultCredentialsProvider`+`Region.of(...)` 建 client 而非抛,镜像 legacy;仅当既无 storage 又无 region 才 fail-loud。 + +### M7 — P6-5:iceberg REST vended-cred region 别名收窄(仍然) + +-

落 `DefaultAwsRegionProviderChain`→**"Unable to load region"**。javadoc `:78-83` 自称"mirror legacy `getRegionFromProperties`"**不实**:legacy 扫所有 `@ConnectorProperty(isRegionField=true)` 别名(S3 就 10 个,含上述被丢的)。 +- **解决方案**:拓宽 `S3_REGION_ALIASES` 对齐 legacy `getRegionFromProperties`(至少加 `AWS_REGION`/`iceberg.rest.signing-region`/`rest.signing-region`,以及 `REGION`/`glue.region`/`aws.glue.region`);fe-connector 不能 import fe-core,连接器侧复制别名列表(与 ENDPOINT 列表同模式)。订正 `:78-83` 注释。 + +### M8 — P6-2:升级只换 `lib/` 不部署 `plugins/connector`(仍然;hms 放大) + +-

fallback→**所有** type=hms 目录(plain-hive+iceberg-on-HMS+hudi-on-HMS)首查即抛,hms/hive 是实际主力外部目录类型→lib-only 升级几乎击穿全部外部目录访问。 +- **性质**:对抗验证把它从"高"降为"设计/运营"——因为它是**有意的 fail-loud**(消息明确、启动有 per-catalog

fe-core schema 缓存绑定,两缓存独立 TTL 过期。外部 ALTER 后两者错时重载→pinned schemaId 与 bound slots 偏斜→BE field-id dict 缺 scan slot→`IcebergScanPlanProvider` 自己注释说会触发 BE StructNode DCHECK 崩溃。legacy 结构免疫(schema 缓存 keyed

`plugins/connector/iceberg`(经典升级手法)→镜像加载 OK,但首次访问任何存量 iceberg catalog 抛 `RuntimeException("No ConnectorProvider found...")`(`PluginDrivenExternalCatalog.java:132`),因为 legacy fe-core `iceberg` fallback 已删。"透明迁移"只在完整部署新 plugins 目录时成立。**需响亮的 release note + 升级文档步骤**(build.sh 部署到 `plugins/connector` 而非 `lib/`)。 +- **⚠️ 守门有洞**(P0):grep 黑名单漏 `import static`、漏

FileSystem.get failure now silently skips partitions (was fail-loud) — recommend fix +- **Where:** `HiveFileListingCache.listFromFileSystem` wraps *both* `FileSystem.get` and `listStatus` in + one `try → DorisConnectorException`; `HiveScanPlanProvider.listAndSplitFiles` catches that and + skips-the-partition-with-a-warning. +- **Legacy (pre-cache):** `FileSystem.get` ran *outside* the inner try → its `IOException` propagated and + the caller re-threw it as `DorisConnectorException` = **fail loud**. Only `listStatus` failures were + skipped-with-warn. So legacy drew a deliberate line: *storage-init failure = loud; one unreadable + partition dir = tolerate.* +- **Now:** both are skipped. A `FileSystem.get` failure is **systemic** (all partitions of a table share + one scheme+authority → it fails for all or none), so a broken storage config makes the scan **silently + return empty/partial results with no error**, where legacy failed the query loudly. +- **The documented mitigation does not hold.** The design doc accepts this because "a broken storage + config still fails loud via the row-count estimate." Verified false: `estimateDataSize` + (`HiveConnectorMetadata.java:771`) **catches `RuntimeException` and returns -1** — it degrades silently, + never throws to the user; and for a table that already has HMS stats the estimate path is not even + invoked. So nothing surfaces the error. +- **Verify verdict:** CONFIRMED, regression-vs-legacy = true. Severity medium (silent wrong *results*, not + a crash; narrow trigger = storage misconfig). +- **Suggested fix:** restore the legacy distinction — let a `FileSystem.get` (FS-resolution) failure + propagate loud while a per-directory `listStatus` failure stays skip-with-warn. (Options in the handoff.) + +### 2. REFRESH DATABASE does not drop the connector-owned caches — accept-deferred (documented) +- **Where:** `RefreshManager.refreshDbInternal → ExternalDatabase.resetMetaToUninitialized → + ExtMetaCacheMgr.invalidateDb`. There is no `Connector.invalidateDb` SPI, so for a flipped hive catalog + `REFRESH DATABASE` drops the fe-core schema cache but **not** the connector's partition/file caches. +- Legacy `REFRESH DATABASE` dropped the engine-side caches for the whole db; post-flip it won't → a user + who runs `REFRESH DATABASE` expecting fresh data across the db still sees stale partition/file listings + until TTL / `REFRESH TABLE` / `REFRESH CATALOG`. +- **Verify verdict:** CONFIRMED, regression-vs-legacy = true. Severity medium. +- **Design status:** explicitly signed off as "accept per-table/all coverage; a db-level verb is + Model-B-adjacent" (§4.5).

The pre-cutover ("legacy") implementation still exists in the tree +(mainly under fe/fe-core/src/main/java/org/apache/doris/datasource/maxcompute/ and sibling legacy +classes). Your job: judge the CURRENT cutover implementation INDEPENDENTLY and compare it against the +legacy implementation. +STRICT DISCIPLINE: + - Read ONLY source code: fe/, be/, gensrc/. Use git/grep/file reads. + - DO NOT read anything under plan-doc/ (designs, reviews, decisions-log, deviations-log, HANDOFF, + PROGRESS) and DO NOT rely on any remembered project conclusions. Form your opinion from code alone. + - Make NO assumption that anything "was fixed", "is correct", or "was verified". Treat the current + code as unaudited. + - Every finding MUST cite file:line and state the CUTOVER vs LEGACY behavioral difference and whether + it is a regression (yes/no/unsure). "The code intends X" is not evidence — verify X actually holds. + - Report only real, evidence-backed issues OR genuine cutover-vs-legacy divergences. No speculative + style nits.

Each compute runs IcebergScanPlanProvider.getScanNodeProperties (via the SPI default getScanNodePropertiesResult wrapper, not overridden), which does its OWN remote catalog.loadTable (resolveTable -> IcebergCatalogOps.loadTable -> catalog.loadTable directly; no CachingCatalog, no table-object cache — grep across fe-connector-iceberg and fe-connector-metastore-iceberg found none), then IcebergWriterHelper.getFileFormat -> inferFileFormatFromDataFiles -> unfiltered table.newScan().planFiles() when neither 'write-format' nor 'write.format.default' is in table.properties() (iceberg does not persist the parquet default, so this gate is true for any table whose writer never explicitly set it — far broader than just migrated tables). Mitigation hunt results, all negative for the default config: (1) the cachedPropertiesResult memo (PluginDrivenScanNode:1776-1809) does kill the canonical per-split amplification — getFileFormatType per split hits the memo — but it is deliberately invalidated by convertPredicate, leaving k=2 computes for predicated queries; (2) the iceberg SDK manifest content cache (io.manifest.cache-enabled) is derived default-FALSE (IcebergCatalogFactory DEFAULT_MANIFEST_CACHE_ENABLE=false, legacy parity); (3) the connector's IcebergManifestCache is gated by the same default-off meta.cache.iceberg.manifest.enable flag AND is only consulted on the manifest-level planning path — the infer path's raw table.newScan().planFiles() bypasses it regardless; (4) because each compute loads a FRESH Table (fresh BaseSnapshot objects), not even the manifest-list read is amortized across the two computes or with planScanInternal's later filtered planFiles; (5) IcebergLatestSnapshotCache caches only snapshot-id pins for MVCC, not manifests or format; (6) no (table,snapshot)-keyed memo of getFileFormat exists anywhere in the connector. The redundancy claim also holds: planScan's enumeration already knows each file's format (buildRange reads dataFile.format() at IcebergScanPlanProvider:1073). One correction to the candidate's cost model: the infer scan is early-terminated (first FileScanTask, then close), so on append-only tables it is not a literal whole-table manifest read — per compute it costs one remote loadTable + one manifest-list read + an eager worker-pool-width burst of manifest reads (ParallelIterable fans out before close cancels); on v2 merge-on-read tables with delete files, DeleteFileIndex construction reads ALL delete manifests before the first task is emitted, which IS whole-table-scale remote IO.

Iceberg's IcebergScanPlanProvider.streamingSplitEstimate (404-437) returns the matched-file count only when it reaches num_files_in_batch_mode (DEFAULT_NUM_FILES_IN_BATCH_MODE=1024, line 142) with enable_external_table_batch_mode on (default true, line 407), snapshot present, non-sys, format-version < 3, no servable COUNT pushdown — the gate is exactly as claimed, and by construction N >= 1024 up to the million-file scans the path exists for. The pump runs to full enumeration (backpressure via queue.offer 100ms retries only slows it). (2) Heaviness-as-amplification holds and is UNDERSTATED: per addToQueue call, SplitAssignment takes assignLock (143-156) and calls FederationBackendPolicy.computeScanRangeAssignment on the singleton (line 153), which per call allocates an ArrayListMultimap (226), a new Random + no-op shuffle (228), re-flattens backendMap into a fresh list (231-234) even though the policy's own `backends` field already holds exactly that list (init, line 185), and constructs a ResettableRandomizedIterator whose ctor copies the whole backend collection (ResettableRandomizedIterator.java:36-38) despite the default ROUND_ROBIN strategy (FederationBackendPolicy:148-150) never using it. Additionally — missed by the finding — enableSplitsRedistribution defaults to true (line 92) and its setter is @VisibleForTesting with zero production callers, so equateDistribution (320-343) runs per split: a third backend flatten, Collections.sort O(B log B), and TWO IndexedPriorityQueue builds over all backends per call; this dominates per-call cost. appendBatch (109-129) then offers a singleton collection per call. No hoist/memoize exists at any layer; micro-batching the pump would amortize all of it while preserving needMoreSplit backpressure. Caveats: (a) no remote IO — each call is O(B log B) CPU + ~8 allocations, single-digit microseconds at ~100 BEs; aggregate ~0.2-10 s serialized on the single pump thread at 10^5-10^6 splits, consistent with the finding's own 'individually micro, aggregate seconds' framing; relative to inherent per-split work (buildRangeForTask + splitToScanRange) the amplification is a ~1.5-3x pump-CPU multiplier, not orders of magnitude, and it overlaps BE execution.

Mitigation hunt results: (1) the static consistentHashCache (lines 95-106, used at init:200) only amortizes hash-ring construction, not the per-call rebuilds; (2) batching exists on both sibling paths — the partition-batch flavor passes whole partition batches to addToQueue (PluginDrivenScanNode.java:1565-1570) and the synchronous path assigns all splits in ONE computeScanRangeAssignment call (FileQueryScanNode.java:431) — but not on the streaming pump; (3) no config can raise the pump batch size; (4) consumer-side draining does not help producer-side per-call cost.

(1) HEAVINESS: IcebergPartitionUtils.loadRawPartitions (IcebergPartitionUtils.java:709-723) scans the PARTITIONS metadata table via partitionsTable.newScan().useSnapshot(id).planFiles() + task.asDataTask().rows() — per the SDK cost model a metadata-table scan is REMOTE IO that aggregates over EVERY data+delete manifest of the snapshot (O(#manifests) FileIO avro reads), independent of query selectivity. It is preceded by a catalogOps.loadTable (more remote IO, attributed to a separate finding). This is NOT the data-planning planFiles (that runs separately in IcebergScanPlanProvider), so it is additive, not inherent planning cost. (2) MULTIPLICITY: BindRelation.getLogicalPlan calls StatementContext.loadSnapshots for every bound relation (BindRelation.java:733); loadSnapshots memoizes only in the statement-scoped `snapshots` map (StatementContext.java:993). loadSnapshot on the implicit-latest path calls materializeLatest (PluginDrivenMvccExternalTable.java:343-346, 126), which reaches loadRawPartitions exactly once per statement via one of two branches, both verified: time-transform-eligible tables through getMvccPartitionView (materializeLatest:163-165 -> IcebergConnectorMetadata.java:1448-1454 -> buildMvccPartitionView:532, gate isValidRelatedTable:533 is in-memory specs/schema, scan at :565); all other partitioned tables through listLatestPartitions (materializeLatest:178-181/190 -> :270 metadata.listPartitions -> IcebergConnectorMetadata.java:1500-1513 -> IcebergPartitionUtils.listPartitions:631, scan at :641). So the claimed per-query multiplicity holds exactly. (3) NO MITIGATION: the 24h-TTL IcebergLatestSnapshotCache caches ONLY (snapshotId, schemaId) (IcebergConnectorMetadata.java:1540-1544, IcebergConnector.java:188-189); the IcebergManifestCache is default-off and consumed only by IcebergScanPlanProvider data planning, never by loadRawPartitions (IcebergConnector.java:159-162); no fe-connector-cache entry wraps the partition view. The result is a pure function of the pinned snapshotId, which the TTL cache deliberately keeps STABLE across queries — yet the derived view is re-fetched remotely every query: textbook variant-C cache bypass, with N = QPS over the TTL window.

I hunted every cache layer and none prevents the cross-query repetition in the default config: (1) StatementContext.snapshots (993-996) memoizes per statement only; (2) IcebergLatestSnapshotCache (24h TTL default, IcebergConnector.java:130,188-189) caches only (snapshotId, schemaId) — the partition view derived from that same cached, unchanged snapshot is re-fetched remotely every query, so the cache proves the recomputed value is loop-invariant across the whole TTL window; (3) IcebergManifestCache is consumed only by the scan-provider manifest-planning path (gate meta.cache.iceberg.manifest.enable, default off) and loadRawPartitions bypasses it structurally (SDK PartitionsTable scan); (4) the iceberg SDK FileIO manifest content cache (io.manifest.cache-enabled) is derived default-OFF (IcebergCatalogFactory.java:68 DEFAULT_MANIFEST_CACHE_ENABLE=false, rule at 119-133) — when a user opts in it is only a PARTIAL mitigation (caches manifest bytes; avro decode + per-entry aggregation CPU still paid per query); (5) catalogOps.loadTable is a raw catalog.loadTable delegation (IcebergCatalogOps.java:340-342), no CachingCatalog anywhere; (6) no fe-core meta cache is interposed — materializeLatest calls the connector SPI directly. The scan path reuses the statement pin (PluginDrivenScanNode.pinMvccSnapshot:876-882 via MvccUtil.getSnapshotFromContext), so multiplicity stays per-query, not per-split. This is AMPLIFIED (not inherent) cost: the result is a pure function of the pinned snapshotId which is already served stable from a 24h cache, and the cost is paid regardless of query selectivity — a point-lookup SELECT with a fully selective WHERE still pays an O(#manifests) remote scan at analysis before planning even starts.", + "corrected_multiplicity": "per-query (>= once per statement per partitioned iceberg table, at analysis time via BindRelation.loadSnapshots; per-statement memoization prevents intra-statement repeats and the scan node reuses the pin, so it never grows to per-split — but nothing spans statements, so multiplicity = QPS x #partitioned-iceberg-tables-referenced)", + "mitigation_found": "Partial/off-by-default only.

(2) No connector-level memoization: IcebergConnector.getMetadata builds a NEW IcebergConnectorMetadata per call (IcebergConnector.java:212-214), so instance state could not help; IcebergConnectorMetadata.loadTable (540-547) and IcebergScanPlanProvider.resolveTable (1981-1993) load fresh every call. (3) The only load-avoiding cache on the path is IcebergLatestSnapshotCache (default TTL 24h, IcebergConnector.java:188-209) and it caches ONLY the (snapshotId, schemaId) pin for beginQuerySnapshot (IcebergConnectorMetadata.java:1540-1545) — never the Table. (4) PluginDrivenScanNode.cachedPropertiesResult (1776-1810) is a real memo but only caps the properties result at one computation: it prevents the canonical per-split amplification (FileQueryScanNode.java:485 getFileFormatType per split resolves from the cached map after the first split) — the finding is correctly k-per-query, not per-split. (5) IcebergManifestCache is default OFF (IcebergConnector.java:157-160 comment: consumed only when meta.cache.iceberg.manifest.enable is set). (6) fe-core has a schema cache, but buildColumnHandles (PluginDrivenScanNode.java:1856-1873, no memo) bypasses it and calls connector getColumnHandles which loads the table (IcebergConnectorMetadata.java:587). (7) The partition path is per-query by explicit design with no FE cache (PluginDrivenExternalTable.java:826-831, CACHE-P1 comment) and loads the table again (IcebergConnectorMetadata.java:1507). I additionally found one load the finder MISSED: computeBatchMode calls streamingSplitEstimate for every slotted query (PluginDrivenScanNode.java:1412-1420) and the provider's gate defaults ON (sessionBool(ENABLE_EXTERNAL_TABLE_BATCH_MODE, true), IcebergScanPlanProvider.java:407) before resolveTable at :410 — so even queries that end up on the sync path pay that load plus a manifest-list metadata read. Default sync-path count for an unpartitioned SELECT is therefore 5 loadTable roundtrips (batch probe + buildColumnHandles in getSplits:1202 + planScan resolveTable:562 + buildColumnHandles again:1780 + getScanNodeProperties resolveTable:1300), 6 for partitioned (+listPartitions, which also runs a PARTITIONS metadata-table scan), of which 1 is inherent. Kerberos claim verified: wrapTableForScan (IcebergScanPlanProvider.java:2018-2029) builds a NEW IcebergAuthenticatedFileIO/BaseTable per resolveTable, so any per-FileIO SDK content cache would miss across the repeated loads.

Mitigation hunt results: (a) PluginDrivenScanNode's node-level memo IS effective — cachedPropertiesResult (1776-1809) computes once per scan node; the convertPredicate invalidation (line 797) fires before the first consumer (doFinalize order: convertPredicate at FileQueryScanNode.java:252, first consumption at :325), so the per-split loop (FileQueryScanNode.java:485) never re-triggers it; this caps the finding at k-per-query, exactly as the candidate claims, but does not eliminate the extra planFiles. (b) Doris IcebergManifestCache is disabled by default (DEFAULT_MANIFEST_CACHE_ENABLE=false, IcebergScanPlanProvider.java:201) and, even when enabled, is wired only into planFileScanTaskWithManifestCache (1683-1693) — the helper's raw planFiles bypasses it entirely.

This is a faithful port of the legacy IcebergUtils.getFileFormat (PR #64134 fallback) with the per-split amplification fixed but the per-query redundant whole-manifest-path scan retained. The same un-memoized fallback also re-executes on each write-planning call site (IcebergWritePlanProvider.java:400/464/525/746, IcebergConnectorTransaction.java:658/690), giving multiple planFiles per INSERT on gated tables — lower multiplicity, same pattern.

(2) Neither rewritableDeleteDescs (IcebergScanRange.java:302-313) nor DeleteFile.toThrift (:681-704) memoizes; the fe-connector-cache manifest cache and snapshot caches cover manifest/table loads, not thrift conversion — nothing at any layer caches these descs. (3) The stash conversion runs for plain SELECTs too: the stash is constructed unconditionally (IcebergConnector.java:167) and wired into every scan provider (:589-591); the only gate is formatVersion>=3 (IcebergScanPlanProvider.java:613); and v3 is explicitly barred from the streaming path (streamingSplitEstimate returns -1 at :416-418), so every v3 scan of any size takes the eager loop with the side-effect.

(1) MITIGATED (as the finder noted): the per-split getFileFormatType at FileQueryScanNode:485 routes through PluginDrivenScanNode:527-534 -> getOrLoadScanNodeProperties:1815-1823 -> getOrLoadPropertiesResult:1776-1810, which caches in cachedPropertiesResult/scanNodeProperties fields — the connector round trip runs once per scan, not per split. (2) NOT mitigated: PluginDrivenSplit.buildPath (PluginDrivenSplit.java:76-79) calls LocationPath.of(String) (LocationPath.java:163-169) per range at all three split-materialization sites (eager :1248, partition-batch :1567, streaming pump :1640); of(String) runs encodedLocation (URLEncoder.encode over the full path + two String.replace, LocationPath.java:346-354) + URI.create per call, on a path the connector ALREADY normalized (IcebergScanPlanProvider.normalizeUri:1222, applied at .path() build sites :874/:1105/:1157). Telling detail: LocationPath ships purpose-built mitigations — ofDirect (:215-220) and ofWithCache (:232+, javadoc: 'optimized for batch processing where many files share the same bucket/prefix') — but grep shows ZERO callers in fe-core main; the mitigation exists and is not wired to this path. (3) NOT mitigated: splitToScanRange re-parses the same string a third time via new Hadoop Path in toStorageLocation (LocationPath.java:404-406, called at FileQueryScanNode:573) and, for HDFS location type, a FOURTH time via getPath() (new Path, LocationPath.java:435-437) just to derive fsName (:574-576) — fsName is identical for every split sharing a filesystem, loop-invariant, never hoisted. (4) NOT mitigated (but gated): the parent builds columns-from-path value/isNull lists (normalizeColumnsFromPath FileQueryScanNode:478, FilePartitionUtils.java:158-174) and sets three thrift fields (:566-570) that IcebergScanRange.populateRangeParams unconditionally unsets and rebuilds from its own partitionValues map (IcebergScanRange.java:435-451). Partial natural mitigation: the thrift set/unset dead work only materializes when path_partition_keys is non-empty, i.e. identity-partitioned iceberg tables (IcebergScanPlanProvider.java:1325); unpartitioned tables hit the empty fast path (FilePartitionUtils.java:159-161). (5) NOT mitigated: getFileCompressType per split (FileQueryScanNode:482 -> PluginDrivenScanNode:602-610) calls resolveScanProvider (:224-226) -> Connector.java:85 default -> IcebergConnector.getScanPlanProvider (:583-592) which constructs a FRESH IcebergScanPlanProvider per call, plus a TCCL swap (onPluginClassLoader :633-641). No field in PluginDrivenScanNode caches the resolved provider despite 10+ resolveScanProvider call sites. The ctor is 5 field assignments (IcebergScanPlanProvider.java:261-270, catalog is behind a lazy resolver), so this is ~100ns of allocation per split — real, unmitigated, but the smallest item. Severity caveat (honest scrutiny): every unmitigated item is LOCAL CPU at micro-scale — no remote IO, no O(table) compute. This is a genuine D-variant (loop-invariant not hoisted, no cache at any layer, default config, every plugin-driven iceberg scan) but at the bottom of the severity range for this problem class: the per-split parse quadruple-up is the dominant term and the whole bundle is ~3-8us/split, invisible below ~10k splits and a few hundred ms of planner CPU + GC pressure at 100k splits, where manifest IO and thrift serialization likely still dominate.

Data files are byte-sliced by TableScanUtil.splitFiles (IcebergScanPlanProvider.java:463 streaming, :1657 eager) and each slice independently runs buildRange, which recomputes the per-file-invariant partition JSON (:1056), identity map (:1060) and rebuilds the delete-carrier list via buildDeleteFiles (:1117, :1129-1139) — SDK SplitScanTask.deletes() returns the parent file's full delete list, so all k slices of one file carry the full list, and the SDK DeleteFileIndex attaches a shared equality/partition-wide delete to every matching data file, giving the claimed M x k copies. (2) Heaviness: this is the 'large thrift structure serialization / loop-invariant thrift substructure rebuilt per iteration' category the problem-class doc explicitly lists (heavy-op bullet 3 and variant D); per-unit cost is small so it is material only on v2+ MOR tables with many deletes and/or high split counts — exactly the gate the candidate states.

Legacy regression confirmed in git 83585fd5097^: legacy IcebergScanNode's count branch (line 853) enumerated tasks via planFileScanTask (cache gate at 537-542), i.e. it honored the cache. getCountFromSnapshot itself is in-memory (snapshot.summary(), :1913-1918) — the planFiles call exists only to fetch one file path for the collapsed range, so the heavy op does far more work than the information needed. Heaviness: scan.planFiles() = manifest-list read + ALL matched delete-manifest reads (DeleteFileIndex builds before the first data task) + O(worker-pool) data-manifest reads before close — remote IO per the SDK cost model. One nuance refines but does not refute: the same FE gate also derives the SDK's byte-level cache io.manifest.cache-enabled=true (IcebergCatalogFactory.java:119-133), and iceberg-core 1.10.1 bytecode confirms ManifestGroup->ManifestFiles.read honors it — BUT for the default HMS flavor (connector never sets io-impl; grep verified) HiveCatalog.initialize creates new HadoopFileIO(conf) WITHOUT properties (verified via javap), so io.properties() is empty, ManifestFiles.cachingEnabled=false, and no SDK cache applies: the count path pays real remote manifest IO per query while the enabled, warm Doris cache is skipped.

(1) Heaviness holds: line 275 `snapshot.deleteManifests(icebergTable.io())` forces the SDK to read that snapshot's manifest-LIST file via FileIO (BaseSnapshot.cacheManifests — remote IO, one per snapshot, since each snapshot has its own manifest-list file), and line 280 `ManifestFiles.readDeleteManifest(manifest, io, specs)` opens and fully iterates the delete-manifest avro — remote IO per call, squarely in the given SDK cost model. The only in-memory call in the loop is `icebergTable.specs()`. (2) Multiplicity holds as claimed or worse: the outer loop (line 274) walks EVERY snapshot in table history; `Snapshot.deleteManifests` returns ALL delete manifests visible at that snapshot (the full live set from its manifest list, not the delta), so consecutive snapshots share nearly all manifests, and there is no visited-manifest-path set — the same manifest file is fully re-read for each snapshot referencing it. The only dedup is per-DeleteFile `putIfAbsent` (line 283) which runs AFTER the remote read, so it prevents no IO. Total = O(S) manifest-list reads + O(S x M) delete-manifest reads where O(distinct manifests) suffices. Note it is even worse than claimed in one dimension: even for an append-only table with zero delete files, the per-snapshot manifest-LIST read at line 275 still occurs for all S snapshots (the emptiness check at 276 requires the list to have been read). (3) Cost actually incurred: the action is registered (IcebergExecuteActionFactory.java:51,81) and dispatched via IcebergProcedureOps.execute (:116) -> runInAuthScope (:175/:179 `action.execute(ops.loadTable(...))`) -> BaseIcebergAction.execute (:109-110) -> executeAction, which calls buildDeleteFileContentMap unconditionally (IcebergExpireSnapshotsAction.java:168-169) before ExpireSnapshots is even configured, regardless of arguments. The map's sole consumer is the deleteWith counter classification (:215-231). The one potential mitigation — the Iceberg SDK ContentCache via `io.manifest.cache-enabled` — is derived from `meta.cache.iceberg.manifest.enable` whose default is false (IcebergCatalogFactory.java:68 DEFAULT_MANIFEST_CACHE_ENABLE=false; derivation :119-133), so by default every readDeleteManifest is an uncached remote read; per the audit rules a disabled-by-default cache does not refute.

No memoization exists at any layer: MvccUtil.getSnapshotFromContext (MvccUtil.java:35-45) delegates to StatementContext.getSnapshot (StatementContext.java:1015-1034), a passive map lookup with no lazy load; at MTMVTask lines 221/228/243 the thread's ConnectContext has no populated StatementContext (MTMVPlanUtil's temp contexts at MTMVPlanUtil.java:222-230/259-267 are closed and restored before returning), so every accessor gets Optional.empty() and re-materializes. MTMVRefreshContext.java:35 caches only MTMVSnapshotIf table snapshots, never the partition view. Heaviness: each iceberg materializeLatest pays a remote tableExists RPC (PluginDrivenExternalTable.java:116-119 -> IcebergConnectorMetadata.java:324), an UNCACHED catalogOps.loadTable (raw SDK delegation, IcebergCatalogOps.java:340-341; no CachingCatalog wrap anywhere in fe-connector-iceberg/metastore-iceberg), and a PARTITIONS metadata-table newScan().useSnapshot(id).planFiles() (IcebergConnectorMetadata.java:1453-1454 -> IcebergPartitionUtils.java:710-712) — remote manifest-list+manifest IO per the SDK cost model.

(2) PluginDrivenMvccExternalTable.loadSnapshot -> materializeLatest runs per statement (PluginDrivenMvccExternalTable.java:343-346, 126-193); it always calls metadata.getMvccPartitionView (:165), and for a non-RANGE view on a table with partition columns additionally listLatestPartitions -> metadata.listPartitions (:181, :270). (3) Both connector methods do a BARE catalogOps.loadTable (IcebergConnectorMetadata.java:1453 and :1507) — IcebergCatalogOps.CatalogBacked.loadTable is a direct catalog.loadTable with no CachingCatalog anywhere in the connector/metastore modules (IcebergCatalogOps.java:340-341; grep for CachingCatalog: zero hits) — then scan the PARTITIONS metadata table: buildMvccPartitionView -> loadRawPartitions (IcebergPartitionUtils.java:565) or listPartitions -> loadRawPartitions (:641), which is partitionsTable.newScan().useSnapshot(id).planFiles() + row iteration (:712-717) = manifest-list read + O(manifests) manifest reads/avro decode, remote IO. Mitigation hunt results, all partial or off-by-default: (a) IcebergLatestSnapshotCache (default TTL 86400s, IcebergConnector.java:130,188-189) caches ONLY the beginQuerySnapshot (snapshotId, schemaId) pin (IcebergConnectorMetadata.java:1540-1545) — the partition enumeration and its loadTables run outside it; (b) the iceberg FileIO manifest byte cache is derived on only from meta.cache.iceberg.manifest.enable, whose default is FALSE (DEFAULT_MANIFEST_CACHE_ENABLE=false, IcebergCatalogFactory.java:68, derivation :120-133), so in default config every PARTITIONS scan re-reads all manifests remotely; (c) IcebergManifestCache is also gated on that same default-off knob and is consumed only by the data-scan provider — IcebergPartitionUtils has zero references to it (IcebergConnector.java:159-160); (d) the FE second-level partition cache was deliberately dropped (CACHE-P1 comment, PluginDrivenExternalTable.java:826-827); (e) downstream readers (getNameToPartitionItems/getPartitionType at PluginDrivenMvccExternalTable.java:580-599) correctly reuse the statement pin, so there is no intra-statement amplification — the problem is purely cross-statement. Iceberg declares SUPPORTS_MVCC_SNAPSHOT (IcebergConnector.java:652) so every iceberg table reference takes this path. Legacy master served this from IcebergMetadataCache within TTL; the cutover replaced a cache hit with a full remote enumeration per query, keyed data (pure function of snapshotId, which the TTL-cached pin already supplies) making it trivially memoizable. One refinement: for identity/bucket/truncate-partitioned tables the path pays TWO uncached loadTables per statement (getMvccPartitionView loads, returns unpartitioned verdict without scanning; listPartitions loads again before the single PARTITIONS scan), and even unpartitioned iceberg tables pay one uncached loadTable per query (early return at IcebergPartitionUtils.java:632-637 / isValidRelatedTable=false comes after the load at IcebergConnectorMetadata.java:1453).", + "evidence": [ + { + "file": "fe/fe-core/src/main/java/org/apache/doris/nereids/rules/analysis/BindRelation.java", + "line": 733, + "note": "loadSnapshots invoked for every table reference during binding (before the type switch), so every statement referencing an Mvcc table triggers a pin materialization." + }, + { + "file": "fe/fe-core/src/main/java/org/apache/doris/nereids/StatementContext.java", + "line": 993, + "note": "snapshots.containsKey dedupe is per-StatementContext (per statement, keyed by table+version selector); no cross-statement layer exists here.

结论 | +|---|---| +| **整个 `property/` 包整体搬出成一个 module？** | **不可行 / 代价过大**。`metastore` 子包（28 文件）直接构造 iceberg/paimon/hive/glue/dlf 的 catalog、直接 import 这些重型 SDK，并且 import 了 fe-core 的 `IcebergExternalCatalog/PaimonExternalCatalog/DLFCatalog`——而这三个类又**反向 import 了 property 包**，构成 Maven 无法接受的循环依赖；此外 Glue 客户端是**以源码形式 vendored 在 fe-core 里**（38 个 .java），根本没有可引用的 maven 坐标。 | +| **拆分：只把 `storage` + `common`(纯AWS部分) + `constants` + `ConnectionProperties` 搬出？** | **可行，中等工作量**。这部分**零 iceberg/paimon 依赖**，对 fe-core 的反向依赖只有 1 个（`common.util.S3URI`，自包含工具类，下沉即可），重型依赖只剩 hadoop + aws-sdk，可用 `provided` scope 排除出最终 jar。 | +| **重依赖如何不进最终 jar？** | 用 `provided`（编译期可见、不打包）。这正是用户的硬约束所要求的，且 fe-core 与各 SPI 插件运行时本就自带 hadoop/aws，late-binding 天然成立。 | +| **该并入现有 `fe-foundation` 吗？** | **不该**。`fe-foundation` 的 pom 只依赖 `fastutil-core`，零重依赖是它的立身之本（被 fe-catalog、fe-filesystem、SPI 插件当"轻基座"依赖）。塞入 hadoop/aws 会污染所有下游。应新建 `fe-property` 模块，依赖 `fe-foundation`。 | + +**一句话**：用户"把属性解析做成可复用 module"的诉求，对**最有复用价值的对象存储（storage）解析**是成立且推荐的——这恰好就是 minio 那个修复（`PaimonCatalogFactory` 重写 minio.* 解析）本应复用的部分；但 `metastore`（catalog 连接/构造）本质是 fe-core 领域逻辑、不是"通用属性解析"，应留在 fe-core。 + +--- + +## 1. 背景与动机 + +`47bfe201c7c`（FIX-PAIMON-MINIO-STORAGE）在 SPI 连接器 `PaimonCatalogFactory` 里**重新实现**了一套 `minio.*` 属性识别逻辑，而同样的逻辑在 `datasource/property/storage/MinioProperties` 中早已存在。根因是：这套属性解析代码被关在 `fe-core` 内部，**module 外（如 fe-connector 的 SPI 插件）无法依赖复用**（fe-connector 还有 import-gate 禁止反向依赖 fe-core 内部）。因此用户希望把 `property/` 抽成独立 module 供各方复用，并要求**重型依赖（hadoop/hdfs/aws/iceberg/paimon…）不得出现在该 module 的最终 jar 里**。

metastore**——把 metastore 留在 fe-core，新 module 就彻底不碰它们。 + +--- + +## 5. 对抗式复核要点（surface conflicts） + +两个 verifier 对"原始综述"提出关键修正，已采纳并在本报告中纠正： + +1. **"整包搬出后 module 不再需要 iceberg/paimon/aws"——证伪。** metastore 的 `*Properties` 本身就是 catalog 构造层（`AbstractIcebergProperties.initCatalog():Catalog`、`AbstractPaimonProperties.initializeCatalog():Catalog`），**直接 import 并 new iceberg/paimon catalog**，不止 `DLFCatalog` 一处。所以"只上提常量+反转 DLFCatalog"并不能让整包摆脱重型 SDK。→ **正确做法是不搬 metastore。** +2. **Glue 是 vendored 源码（38 文件）而非依赖——证实。** `HiveGlueMetaStoreProperties` import 的 `com.amazonaws.glue.catalog.util.AWSGlueConfig` 在整个仓库只存在于 fe-core.jar；无 `provided` 坐标可加。→ **又一条 metastore 必须留在 fe-core 的硬理由。** +3. **循环依赖（catalog 类反向 import property 包）——证实**（见 4.3）。 + +这些修正不削弱"storage 子集可抽出"的结论，反而把"metastore 不可抽出"钉死，使最终方案更清晰。 + +--- + +## 6. 推荐方案 + +### 6.1 新建 `fe-property` 模块，抽出"干净子集" + +**搬入 `fe-property` 的内容（约 25 文件）：** +- `storage/*`（20）+

`common/IcebergAwsClientCredentialsProperties.java`、`common/IcebergAwsAssumeRoleProperties.java`（2，import iceberg，仅被 metastore 用） + +### 6.2 搬迁前置改造（precondition fixups） + +1. **下沉 `S3URI`**：把 `common.util.S3URI`（403 行，自身仅依赖 UserException）移到 `fe-property`（或 fe-common）。这是 storage 唯一的 fe-core 反向依赖，移走后 storage 对 fe-core 零依赖。 +2. **避免 split-package**：`property.common` 若一半在 fe-property、一半在 fe-core，会造成同一个包跨两 jar（JVM/Maven 不允许）。解法：把 2 个 iceberg-aws 辅助类从 `property.common` **挪进 `property.metastore`**（它们只被 metastore 用），使 `property.common` 整体进入 fe-property。 +3. **修正 `HttpProperties` 的误引**：它

jar）**：`hadoop-common`、`hadoop-hdfs-client`、`hadoop-aws`、`software.amazon.awssdk:{auth,sts,regions,s3,s3tables}`。**无需 iceberg/paimon/hive/glue/dlf**（都随 metastore 留在 fe-core）。 +- **建议加 fe-connector 式的 import-gate**（exec-maven-plugin，validate 阶段）禁止 `fe-property` import `org.apache.doris.datasource.{iceberg,paimon}` 及 fe-core 内部包，防止循环依赖复发。 + +### 6.4 构建顺序与消费 + +- 在 `fe/pom.xml` 的 `` 中把 `fe-property` 放在 `fe-foundation/fe-common/fe-thrift/fe-grpc/fe-catalog` 之后、`fe-core` 之前（Maven 实际按依赖图排序，列表顺序对齐即可）；在 parent dependencyManagement 加 `fe-property` 条目。 +- `fe-core/pom.xml` 增加一条对 `fe-property` 的 compile 依赖；删除已搬走的源码。fe-core 运行时本就带 hadoop/aws，`provided` 依赖透明解析。 +- **保持 FQN 不变**（`org.apache.doris.datasource.property.storage/common/constants`）：由于每个叶子包整体只落在一个 jar（storage/common/constants→fe-property，fileformat/metastore→fe-core，无包被劈开），fe-core 里 metastore/fileformat 对已搬类的 import **无需改动**，仅物理移动文件。 + +--- + +## 7. 风险与坑 + +1. **hive-catalog-shade / paimon-hive-shade 版本耦合**：`HiveConf`、DLF、iceberg-hive、paimon-hive 在 fe 里运行时来自**relocate/shade** 的制品（HMS 钉 2.3.7、thrift relocate、内嵌远古 fastutil）。本方案把这些**全留在 fe-core**，规避了该坑；若将来要搬 metastore 必须正面处理。 +2. **vendored Glue 源码（38 文件）**：`metastore` 留在 fe-core 即可继续编译；不可低估其搬迁成本。 +3. **`S3URI` 下沉**：需确认其无其它 fe-core 专属依赖（初查仅 UserException，干净）。下沉后 fe-core 内其它调用方自动从下层 module 解析（fe-core 仍依赖 fe-property，无碍）。 +4. **`ConnectContext` 反转**：`fileformat` 留在 fe-core，本次不涉及；仅当未来要抽 fileformat 时才需做 SessionFlags 接口反转。 +5. **fe-thrift / fe-grpc 是真实编译依赖**（S3Properties 用 `TS3StorageParam/TCredProviderType` + `cloud.proto.Cloud`），不是可选项，pom 必须显式声明。 +6. **`provided` 的运行时契约**：消费方（fe-core、以及将来若依赖它的 SPI 插件）**必须**自带 hadoop/aws。fe-core 满足；SPI 插件本就 child-first 自带 hadoop/aws（见历史 RC-3 self-contained bundling），也满足。 + +--- + +## 8. 工作量与分阶段路径 + +| 阶段 | 内容 | 规模 | +|---|---|---| +| P1 | 前置改造：下沉 `S3URI`；2 个 iceberg-aws 类从 common 挪进 metastore；修 `HttpProperties` 的 hudi 误引 | 小（~5 文件） | +| P2 | 新建 `fe-property` module +

`org/apache/hadoop/**`、`software/amazon/**`、`org/apache/iceberg/**`、`org/apache/paimon/**`、`com/amazonaws/**`； +- fe-core 全量编译通过、storage 相关 UT 全绿； +- fe-connector（或任一 fe-core 之外的 module）能成功 `compile` 依赖 `fe-property` 并调用 `StorageProperties.createAll(...)`（验证"可复用"目标达成）。 + +--- + +## 9. 总结 + +- 用户的设想**部分成立且值得做**：最具复用价值的**对象存储/HDFS/Azure 属性解析（storage）** 是**可干净抽出**的——它零 iceberg/paimon 依赖、对 fe-core 仅 1 处易解的反向依赖、重依赖仅 hadoop+aws 且可 `provided` 排除出 jar。抽出后，fe-connector 等 module 即可复用，**正好消除 minio 那类"在连接器里重写属性解析"的重复**。 +- 但**"把整个 `property/` 搬出"不可行**：`metastore` 子包是 catalog 构造层，直接 new iceberg/paimon/hive/glue/dlf 客户端、import 重型 SDK、依赖 vendored Glue 源码，并与 fe-core 的 `*ExternalCatalog` 构成**循环依赖**。它本质是 fe-core/连接器领域逻辑，不是"通用属性解析"，应留在 fe-core。`fileformat` 无重依赖但深耦合 thrift/nereids/qe，搬迁无收益，亦留在 fe-core。 +- **推荐**：新建 `fe-property`（依赖 fe-foundation，**不并入** fe-foundation 以免污染其零依赖基座），抽 `storage + common(纯AWS) + constants + ConnectionProperties`，重依赖 `provided`，加 import-gate 防循环复发。中等工作量，风险可控。 diff --git a/plan-doc/reviews/prune-pushdown-review.workflow.js b/plan-doc/reviews/prune-pushdown-review.workflow.js new file mode 100644 index

M-8 adds an **internal fe-core hook** `MetastoreProperties.initExecutionAuthenticator(List)` (default no-op, wired in `PluginDrivenExternalCatalog`) — **not** connector SPI (`ConnectorContext`/`Connector` surface unchanged), so 01-spi-extensions-rfc.md is not touched. Scope = filesystem+jdbc only (DLF/REST/HMS excluded, "DLF" clause overstated). True end-to-end doAs is live-Kerberos-e2e only ([DV-031](./deviations-log.md)). +² #4 SPI corrected `maybe`→**`no`** ([D-050](./decisions-log.md)): the fix reuses the **existing** `Connector.preCreateValidation` + `ConnectorValidationContext.validateAndResolveDriverPath` hooks (B-8b) and the existing `paimon.options_json` transport (B-8a) — **zero new SPI surface**, connector-only. Scope = CREATE-time validation parity with the JDBC reference connector; the FE-restart/ALTER/scan-time re-validation gap (pre-existing fe-core, all plugin connectors) is accepted ([DV-028](./deviations-log.md)) + filed as a cross-connector follow-up. BE-side `paimon.jdbc.{user,password,uri}` alias-drop out of scope ([DV-029](./deviations-log.md), BE deserializes the table from `serialized_table`, doesn't rebuild a JdbcCatalog from these). +¹ #3 SPI corrected `yes`→**`no`**: user signed **Design C** ([D-049](./decisions-log.md)) — the connector builds the thrift `TSchema` dict directly from paimon (BE only needs field `id`/`name`/nesting-tag, no Doris `Type`), reusing the existing `populateScanLevelParams` hook → **zero new SPI surface**.

FIX-URI-NORMALIZE — native data-file + DV paths sent to BE un-normalized +- **Findings**: B-7DF (data file), B-7DV (deletion vector). Failure: native ORC/Parquet + DV reads **fail outright** on `oss://`/`cos://`/`obs://`/`s3a://` warehouses (BE S3 factory only recognizes `s3://`). Pure `s3://`/`hdfs://` unaffected. +- **Connector**: `PaimonScanPlanProvider.java:269-276` (`.path(file.path())` raw), `:281-283` (`builder.deletionFile(df.path(),…)` raw); `PaimonScanRange.java:190-200`. +- **fe-core**: `PluginDrivenSplit.java:65-68` (single-arg, NON-normalizing `LocationPath.of`); `PluginDrivenScanNode`. +- **Legacy parity**: `source/PaimonScanNode.java:295-298` (DV) and `:443` (data file) — both use the **2-arg** `LocationPath.of(path, storagePropertiesMap).toStorageLocation()`. +- **Fix sketch**: connector can't import `LocationPath` → normalize in the fe-core bridge (`PluginDrivenSplit.buildPath` + the DV desc build in `PluginDrivenScanNode`/`PaimonScanRange`) using the storage-properties map, **or** add a `ConnectorContext` path-normalization SPI hook (mirror the `FIX-REST-VENDED` seam). Apply to **both** the data-file path and the DV path. +- **Test**: connector/bridge UT asserting an `oss://` input → `s3://` BE-bound path for both data + DV; live-e2e (OSS warehouse + DV) is CI-gated. + +### 2. FIX-STATIC-CREDS-BE — static object-store creds reach BE as RAW keys +- **Finding**: B-9. Static `s3.*`/`oss.*`/`cos.*`/`obs.*` catalog creds are copied verbatim under `location.`; BE native reader wants `AWS_ACCESS_KEY`/`AWS_SECRET_KEY`/… → no usable creds → 403 on private buckets. (FIX-REST-VENDED fixed the *vended* seam; FIX-STORAGE-CREDS fixed the *catalog FileIO* seam — this is the **third, static→BE-scan seam**, see review §9.3.) +- **Connector**: `PaimonScanPlanProvider.java:347-356` (`getScanNodeProperties`, raw copy under `location.*`). +- **fe-core**: `PluginDrivenScanNode.java:307-320` (`getLocationProperties` only strips the `location.` prefix — no normalization). +- **Legacy parity**: `source/PaimonScanNode.java:176,650-652`; `AbstractS3CompatibleProperties.java:105-122` (canonical alias → `AWS_*`); BE `s3_util.cpp:146-150`. +- **Fix sketch**: normalize static aliases to BE `AWS_*` before they leave FE — reuse / extend the `ConnectorContext.vendStorageCredentials` normalization tail for static keys, or normalize in the bridge. Also covers the bare `AWS_*`/`access_key` (no `s3.` prefix) case currently dropped entirely. +- **Test**: UT mutating the connector test that currently codifies the raw key (`PaimonScanPlanProviderTest.java:535`) → assert BE-bound `AWS_ACCESS_KEY` present; live-e2e CI-gated (private S3/OSS). + +### 3. FIX-SCHEMA-EVOLUTION — native reader loses paimon schema-evolution (+ field-id) +- **Findings**: B-1a (BLOCKER, silent wrong/NULL rows on column rename/reorder via native reader) + M-10 (MAJOR, `Column.uniqueId` left -1 — its root cause; standalone repro refuted but it feeds B-1a's BE contract). +- **Connector**: `PaimonScanRange.java:181-184` (only sets per-file `schema_id`); `PaimonScanPlanProvider.java:276`; `PaimonConnectorMetadata.java:1007-1012` (5-arg `ConnectorColumn`, no field-id); `ConnectorColumnConverter.java:65-70` (→ `uniqueId=-1`). +- **fe-core**: `PluginDrivenScanNode` never calls `ExternalUtil.initSchemaInfo` / sets `current_schema_id` / `history_schema_info`. +- **Legacy parity**: `source/PaimonScanNode.java:169` (`initSchemaInfo(-1L)`), `:285` (`putHistorySchemaInfo` per native split); `ExternalUtil.java:86-92`; `PaimonUtil.getHistorySchemaInfo`; `PaimonExternalTable.java:349-355` + `PaimonUtil.java:318-347` (recursive `updatePaimonColumnUniqueId`, incl. nested ARRAY/MAP/ROW). +- **BE contract (frozen)**: `be/src/format/table/table_schema_change_helper.h:219-236` falls back to `by_parquet_name`/`by_orc_name` when `history_schema_info` is unset; field-id path is `:241-267`. +- **Fix sketch**: (a) thread paimon `DataField.id()` through SPI `ConnectorColumn` (+ nested) → `Column.setUniqueId`; (b) emit `current_schema_id` + per-split `history_schema_info` on the native path via the bridge (`PluginDrivenScanNode` → `ExternalUtil.initSchemaInfo` + per-split schema). Largest SPI surface of the P0 set. +- **Test**: UT asserting the native split params carry `current_schema_id` + history schema; e2e = `test_paimon_full_schema_change.groovy` (rename over ORC/Parquet) CI-gated. + +### 4. FIX-JDBC-DRIVER-URL — JDBC flavor driver_url unresolved + unvalidated +- **Findings**: B-8a (raw unresolved `jdbc.driver_url` + dropped `paimon.jdbc.*` alias → `MalformedURLException`) + B-8b (security allow-list / format / secure-path not enforced → arbitrary remote jar in FE JVM; stale "not in SPI_READY_TYPES" disclaimer). +- **Connector**: `PaimonScanPlanProvider.java:549-565` (forwards `jdbc.*` verbatim); `PaimonConnector.java:232-247,206-216,249-287` (`resolveFullDriverUrl` — no validation); `:230` (stale disclaimer). +- **Legacy parity**: `PaimonJdbcMetaStoreProperties.java:164-176` (emits `jdbc.driver_url=getFullDriverUrl(resolved)`), `:190`; `JdbcResource.java:300-329` (format + `checkCloudWhiteList` + `jdbc_driver_secure_path`). +- **Fix sketch**: resolve `driver_url` via `getFullDriverUrl` on the BE-options path + honor the `paimon.jdbc.*` alias (B-8a); enforce the FE security allow-list/format/secure-path — the wired hook is `ConnectorValidationContext.validateAndResolveDriverPath` (jdbc/trino override `preCreateValidation`); paimon must override it (B-8b). Remove the stale disclaimer. +- **Severity note (cross-check)**: round-1 rated the *security* facet PARTIAL ("default `jdbc_driver_secure_path="*"` → legacy also loads any jar"). B-8a (functional `MalformedURLException`) is unambiguous; for B-8b confirm whether to treat as BLOCKER or hardened-config-only — **fold both into one fix regardless.** + +--- + +## P1 — MAJOR (fix or explicitly accept) + +### 5. FIX-MAPPING-FLAG-KEYS — type-mapping flags silently dead (wrong column types) +- **Finding**: M-crit (critic-surfaced; **not 3-lens-gated → re-verify first**). Connector reads underscore keys `enable_mapping_binary_as_varbinary` / `enable_mapping_timestamp_tz`; FE/legacy set DOTTED keys `enable.mapping.varbinary` / `enable.mapping.timestamp_tz` → flags stuck false → BINARY→STRING and LTZ→DATETIMEV2 even when the user enabled the mapping. +- **Connector**: `PaimonConnectorProperties.java:39,42`; read `PaimonConnectorMetadata.java:1017-1027`; consumed `PaimonTypeMapping.java:130-165`. **Legacy**: `CatalogProperty.java:50,52`; `ExternalCatalog.setDefaultPropsIfMissing:302-306`; `PaimonUtil.paimonPrimitiveTypeToDorisType:253,257,283-286`. +- **Fix sketch**: read the dotted keys the FE actually sets (and reconcile the renamed `varbinary` key), or normalize dots→underscores in `PluginDrivenExternalCatalog.createConnectorFromProperties` before constructing the connector. Pure connector/FE-wiring; no BE. +- **Test**: UT constructing the connector with `{"enable.mapping.timestamp_tz":"true"}` → assert LTZ column maps to TIMESTAMPTZ (closes critic coverage-gap #2). + +### 6. FIX-KERBEROS-DOAS — UGI doAs lost on fs/jdbc ops + partition listing +- **Findings**: M-8 (filesystem/jdbc over Kerberized HDFS lose `doAs` — `initializeCatalog` dead on cutover path; HMS unaffected) + M-11 (MTMV / SHOW PARTITIONS / partitions-TVF partition listing runs the `listPartitions` RPC without `doAs` on Kerberos HMS). Grouped: same authenticator mechanism. +- **Connector**: `PaimonConnector.java:124-196` (M-8); `PaimonCatalogOps.java:249-251`, `PaimonConnectorMetadata.java:892-894` (M-11). **fe-core**: `PluginDrivenExternalCatalog.java:122-137,150`; `PluginDrivenMvccExternalTable.java:157`; `PluginDrivenExternalTable.java:317-318`. +- **Legacy parity**: `PaimonFileSystemMetaStoreProperties.java:40-57`, `PaimonJdbcMetaStoreProperties.java:111-135` (M-8); `PaimonExternalCatalog.java:96-118` (`executionAuthenticator.execute` wrap), `metacache/paimon/PaimonPartitionInfoLoader.java:49` (M-11). +- **Fix sketch**: wire the fs/jdbc HDFS authenticator on the live (connector) create path; wrap the partition-listing read RPC in `executeAuthenticated` (note round-1 D7=B deliberately left read-vs-DDL asymmetric — confirm whether to wrap reads too). Scope = secured HMS/HDFS deployments. **Verify the M-8 "DLF" clause** (review says it's overstated; DLF inherits the no-op authenticator). + +### 7.

filesystem`。脚本接受可选 ROOT 参数（默认 `$(dirname $0)/../fe/fe-connector`），自动适配 cwd。当前 baseline 全绿（fe-connector 模块仅引用 `connector / extension / thrift / trinoconnector`）；自构造的负样本（注入 `import org.apache.doris.catalog.Column`）正确报错退出 +- P0-T22 ✅：fe-connector 聚合 pom 加 `exec-maven-plugin` 调用脚本，绑 `validate` 阶段，`inherited=false`（避免 11 个子模块每次都跑同一份扫描）。`executable` 使用 `${project.basedir}/../../tools/check-connector-imports.sh`——不依赖 `directory-maven-plugin` 的 `fe.dir` 属性（后者在 `initialize` 阶段才设值，早于 `validate`）。`mvn -pl fe-connector validate` BUILD SUCCESS +- P0-T23 ✅：fe-core test 包新增 `org.apache.doris.connector.fake.FakeConnectorPlugin`（4 个静态嵌套：`FakeConnector` / `FakeMetadata`（**零** override）/ `FakeSession` / `FakeContext`）。同包测试类 `FakeConnectorPluginTest` 11 个 `@Test` 覆盖：Context.getMetaInvalidator()=NOOP（且 5 个 invalidate 方法 callable）；Session.getCurrentTransaction()=Optional.empty()；Metadata MVCC 3 方法=Optional.empty()；TableOps listTableNames / getTableHandle / listPartitionNames / listPartitions / listPartitionValues / getPrimaryKeys / getTableComment defaults；createTable(request) 退化到 legacy createTable(schema, props) 并抛 "CREATE TABLE not supported"；WriteOps supports*=false + beginTransaction throws；Connector top-level defaults。Tests run: **11/11 green** +- P0-T26 ✅：新增 `org.apache.doris.connector.ExternalMetaCacheInvalidatorTest`。5

名的行为）、invalidateStatistics→**no-op**（pin 当前缺 stats-only entry point 的行为）。用 `MockedStatic` + `Mockito.mock(ExternalMetaCacheMgr)` 完全隔离 FE bootstrap。Tests run: **5/5 green** +- P0-T27 ✅：新增 `org.apache.doris.connector.ddl.CreateTableInfoToConnectorRequestConverterTest`。7 个测试覆盖：列穿透（name/type/nullable/comment）+ scalar 字段穿透（dbName/tableName/comment/properties/ifNotExists/isExternal）+ IDENTITY partition（UnboundSlot）+ TRANSFORM partition（UnboundFunction `bucket(16, id)` + `YEAR(d)` 验证 lowercase normalization + IntegerLiteral 提取）+ LIST partition（PartitionType.LIST）+ RANGE partition（PartitionType.RANGE）+ hash bucket 算法 `doris_default` + random bucket 算法 `doris_random`。用 `Mockito.mock(CreateTableInfo)` 绕开 18-arg 构造器与 `PropertyAnalyzer.getInstance()` 调用；PartitionTableInfo/DistributionDescriptor/ColumnDefinition/UnboundFunction 等都用真实构造器。Tests run: **7/7 green** +- 验证： + - `tools/check-connector-imports.sh` 正/负冒烟测试通过 + - `mvn -pl fe-connector

§17 范围内的实现取舍）： + 1. 守门脚本挂到 `exec-maven-plugin` 而非 `maven-enforcer-plugin`——RFC §15.4 原文写"挂到 maven enforcer plugin"，但 enforcer 没有原生 shell-exec rule（要么写自定义 Java Rule 类，要么用 `EvaluateBeanshell`）。`exec-maven-plugin` 在 fe-common 已是既有 dep（make + protoc 都用它），引入零新依赖。效果等价：脚本 non-zero exit → maven `BUILD FAILURE` + 2. 守门绑 `validate` 阶段且 `inherited=false`——只在 fe-connector aggregator 一次运行；devs 跑 `mvn -pl fe-connector/fe-connector-iceberg compile` 时不会自动触发，但 CI 跑顶层 `mvn install` 必扫。Trade-off：少 11 次重复扫，换"单模块增量构建本地无守门" + 3. ConnectorMetaInvalidator 的 partition fallback 测试明确 pin 当前"回退到 invalidateTable"的行为——一旦未来 SPI 在 invalidatePartition 中加 column 名携带能力可以做精确失效，bridge 和这个测试必须同步更新；测试已留 inline comment 描述意图 + 4. CreateTableInfo 用 Mockito.mock 而非真实构造器——RFC §15.2 没规定单测必须用真实输入对象。Trade-off：测试更聚焦于 converter 自身逻辑（不必维护 18-arg 输入构造），但代价是如果 CreateTableInfo 加新 getter 且 converter 改用之，需要在 stubInfo helper 加新 stub +- T24/T25 转交用户：用户在本地跑 JDBC + ES regression-test（containers / docker 在本地环境下更稳）。任务状态保持 ⏳，owner @用户 + +### 2026-05-24（夜 ②）— 批 1 DDL + Partition SPI 完成（T13-T20） + +- P0-T13 ✅：新增 `connector.api.ddl` 包 5 个 POJO：`ConnectorCreateTableRequest`（带 Builder）、`ConnectorPartitionSpec`（Style enum：IDENTITY/TRANSFORM/LIST/RANGE）、`ConnectorPartitionField`、`ConnectorPartitionValueDef`、`ConnectorBucketSpec` +- P0-T14 ✅：`ConnectorTableOps.createTable(session, request)` default 退化到 legacy `createTable(session, schema, props)`（丢弃 partition / bucket / external / ifNotExists） +- P0-T15 ✅：新增 `fe-core/.../connector/ddl/CreateTableInfoToConnectorRequestConverter`。覆盖：（1）columns 经 `ConnectorColumnConverter.toConnectorType()`；（2）partition 通过 `PartitionTableInfo.getPartitionType()` + `getPartitionList()` 判别四种 style；（3）TRANSFORM 解析 `UnboundFunction.getName()` + children 提取 `IntegerLikeLiteral` 参数；（4）bucket 通过 `DistributionDescriptor.translateToCatalogStyle().getBuckets()` 读取桶数 +- P0-T16 ✅：`PluginDrivenExternalCatalog` 新加 `createTable(CreateTableInfo)` override：build session → converter → `connector.getMetadata(s).createTable(s, req)` → wrap `DorisConnectorException` 为 `DdlException` → 写 edit log +- P0-T17 ✅：`listPartitionNames(session, handle)` default 返回 `Collections.emptyList()` +- P0-T18 ✅：`listPartitions(session, handle, Optional filter)` default 返回 `Collections.emptyList()` +- P0-T19 ✅：`listPartitionValues(session, handle, List partitionColumns)` default 返回 `Collections.emptyList()` +- P0-T20 ✅：`ConnectorPartitionInfo` 新增 3 个 long 字段（rowCount / sizeBytes / lastModifiedMillis），`UNKNOWN = -1L` 常量；3-arg 旧构造器委托到 6-arg 新构造器；equals/hashCode/toString 同步更新 +- 验证： + - `mvn -pl fe-connector/fe-connector-api -am compile` → BUILD SUCCESS + - `mvn -pl fe-core -am compile -Dmaven.build.cache.enabled=false` → BUILD SUCCESS + - `mvn -pl fe-core checkstyle:check` → **0 violations** + - `mvn -pl fe-connector/fe-connector-jdbc,fe-connector/fe-connector-es -am compile` → BUILD SUCCESS（下游连接器零修改） +- 已知 trade-off（**未升 DV**，是 RFC 范围内的实现取舍）： + 1. `ColumnDefinition.defaultValue` 是 private `Optional` 且无 public getter——converter 暂传 `null`。等 SPI 在 ConnectorColumn 上增加 typed default-value carrier 时再补 + 2.

After the flip, a hms catalog becomes a `PluginDrivenExternalCatalog` that wraps **ONE** connector (`PluginDrivenExternalCatalog.connector` is single; `PluginDrivenScanNode` always calls `connector.getScanPlanProvider()` no-arg). **There is no per-table connector/provider selection seam anywhere** (`Connector.getScanPlanProvider()` no-arg; `ConnectorTableHandle` empty marker, no `getTableType`; `tableFormatType` computed by connectors but DROPPED at `PluginDrivenExternalTable.toSchemaCacheValue`). So without A, iceberg-on-HMS/hudi tables cannot be routed to the right scanner and B/C/E cannot proceed. A is shared by all three formats and is a public-SPI change → settle it first. + +**Trino comparison**: Trino uses **one connector per format** (separate `hive`/`iceberg`/`delta`/`hudi` catalogs) plus **table redirection** — when a hive catalog encounters an iceberg table it redirects to a configured iceberg catalog (`hive.iceberg-catalog-name`). Doris's locked decision **D-020** is the analogous idea kept inside one gateway: the `"hms"` connector (`HiveConnectorProvider`) overrides `getScanPlanProvider(handle)` and **delegates** to the `-iceberg`/`-hudi` providers by table type. So `fe-connector-hive` becomes the "hms gateway" depending on `-iceberg`/`-hudi`. Approach is locked; **open implementation decisions** (defer to A's design): discriminator shape (enum `getTableType` vs `tableFormatType` string vs per-table capability); whether `tableFormatType` is persisted in the schema-cache/gson image or recomputed. + +## Highest-risk flip decision (surfaces in E/F, coupled to A) +**GSON single-row MVCC conflict**: historically hive + hudi-on-HMS + iceberg-on-HMS all persist as one `clazz=HMSExternalTable` tag. `registerCompatibleSubtype` maps one tag → ONE class, but MVCC is **subclass-gated** (`PluginDrivenMvccExternalTable extends PluginDrivenExternalTable`): plain-hive/hudi need the base class, iceberg-on-HMS needs the Mvcc subclass. Resolutions: (a) re-persist the three types under distinct discriminators during the routing split, or (b) **move MVCC-ness off the subclass to a runtime `ConnectorCapability` check** so one row targets the base class.

同法）。per-table `file_format` 仍胜（插件侧解析）。**注意**：这是 legacy-exact（全局默认 + per-table 覆盖），**未**新增 per-catalog 覆盖属性（legacy 也无；如需可后续加）。 + 2. **显式分区取值 = 保持报错**（非静默忽略）：converter 丢弃取值表达式但 thread

Also assert a plain `transactional=true` insert-only vs full-acid distinction matches D8. +6. **profileLabel** == `"HMS"`; **getTransactionId** returns the ctor id. + +(Integration write/read gate is deferred to P7.4/P7.5 cutover — do NOT run here; tracked as the R-002 gate, Rule 12.) + +--- + +## 7. GAP LIST (design §4 assumptions vs REAL in-tree signatures) +- **GAP-1**: §4.1 `toColumnStatistics` does NOT exist → real: `HmsWriteConverter.toStatisticsParameters(Map,HmsCommonStatistics)` + `toPartitionStatistics(Map)`. Committer typically calls NEITHER (stats params are stamped inside `ThriftHmsClient.addPartitions`/stats overrides). +- **GAP-2**: `ReduceOperator` lives on `HmsCommonStatistics` (`ADD/SUBTRACT/MIN/MAX`), NOT `HmsPartitionStatistics`. Use `HmsCommonStatistics.ReduceOperator.SUBTRACT`. +- **GAP-3 (getTable return type)**: `HmsClient.getTable(db,tbl)` returns **`HmsTableInfo`** (columns `List`, `getLocation()`, `getInputFormat/getOutputFormat/getSerializationLib/getParameters/getSdParameters`), NOT hive-api `Table`. `table.getPartitionKeysSize()==0` → `getPartitionKeys().isEmpty()`; `table.getSd().getLocation()` → `getLocation()`. `TableAndMore.table` field type = `HmsTableInfo`. +- **GAP-4 (columns conversion)**: to fill `HmsPartitionWithStatistics.columns(List)` from `HmsTableInfo.getColumns()` (`List`), convert via public `HmsTypeMapping.toHiveTypeString(ConnectorType)` inline (or add a public `HmsWriteConverter.toFieldSchemas`). `toHiveSchema` is private — do not rely on it. +- **GAP-5 (serde name)**: read DTOs `HmsTableInfo`/`HmsPartitionInfo` expose `getSerializationLib()`; write DTO builder is `.serde(...)`/`getSerde()`. Map `getSerializationLib()` → `.serde(...)`. +- **GAP-6 DISSOLVED**: Reader 4's GAP-6 was wrong — BOTH `ConnectorSession.getCatalogId()` (line 43) AND `ConnectorContext.getCatalogId()` (line 38) exist. `NameMapping` ctlId = `context.getCatalogId()`. (equals/hashCode only needs intra-txn consistency; one NameMapping per txn.) +- **GAP-7 (batch-20 location)**: `Lists.partition(...,20)` is INSIDE `ThriftHmsClient.addPartitions` (INC-1), NOT the committer. `AddPartitionsTask.run` calls `hmsClient.addPartitions(db, tbl, ALL)` once. +- **GAP-8 (probe API)**: HEAD's NEW→APPEND probe used `hiveOps.getClient().getPartition(...)!=null`; use the not-found-tolerant `hmsClient.partitionExists(db, tbl, values)` primitive instead. +- **GAP-9 (fromCommonStatistics arg order)**: `HmsPartitionStatistics.fromCommonStatistics(long rowCount, long fileCount, long totalFileBytes)` — fileCount is the MIDDLE arg. +- **GAP-10 (write primitives take strings)**: all 5 write/stats primitives take `(String dbName, String tableName, ...)`, NOT `NameMapping`. Pass `nm.getRemoteDbName()`/`nm.getRemoteTblName()`. +- **GAP-11 (pathsEqual vs equalsIgnoreSchemeIfOneIsS3)**: HEAD's `needRename` used `PathUtils.equalsIgnoreSchemeIfOneIsS3`; INC-2's `HiveWriteUtils.pathsEqual` is a normalized compare (two nulls equal). **Verify it reproduces the S3-scheme-tolerant semantics**; if not, port `equalsIgnoreSchemeIfOneIsS3` into `HiveWriteUtils`. +- **GAP-12 (HiveUtil.toPartitionValues)**: HEAD used `HiveUtil.toPartitionValues`/`convertToNamePartitionMap` (fe-core). Verify a plugin equivalent exists in `fe-connector-hive`; if absent, port the pure `k=v/...` split. + +--- + +## 8. RISKS carried into implementation (locked by D-decisions; not human-blocking now) +- **R3/D6 provider-discovery (deferred to cutover)**: production `FileSystemProvider` discovery is fe-core/directory-plugin mediated (`FileSystemPluginManager` = classpath ServiceLoader **+** directory-loaded providers in a separate classloader). A plugin-side `ServiceLoader.load(FileSystemProvider.class)` sees ONLY providers on the hive plugin's own/parent classpath → directory-loaded object-store providers may NOT be discovered. **Mitigation**: isolate discovery behind one method (`resolveObjectStoreFileSystem(StorageProperties)`) so it is swappable; the batch is DORMANT (hive not in `SPI_READY_TYPES`) and unit tests inject a fake FS, so the risk does not bite until the P7.4/P7.5 integration gate. See §8 open decision below (D6 locks plugin-side; this is the one place recon flagged a template divergence with a material trade-off). +- **R1/D5 auth on plugin pools**: fs/rename/MPU tasks must each be `context.executeAuthenticated`-wrapped (§3.10). Metastore self-auths. No JVM-wide primer. +- **R4 DTO shape drift**: converter/committer unit tests must exercise exactly the fields the transaction passes (columns/formats/serde/stats), so a missed field is a test gap now, not a signature break. +- Import gate `tools/check-connector-imports.sh` each sub-step; `HiveVersionUtil` hit = known false positive (do not touch). + +--- + +## 9. VERIFIED PRE-IMPLEMENTATION CHECKS (resolved by orchestrator 2026-07-07 — TRUST THESE OVER §7 where they conflict) +- **GAP-11 RESOLVED — `pathsEqual` is NOT equivalent to `equalsIgnoreSchemeIfOneIsS3`.** `HiveWriteUtils.pathsEqual` calls `sameFileSystem(leftUri,rightUri)` which returns false when schemes differ (e.g. `s3://` vs `s3a://`, or s3 vs scheme-less). HEAD's `needRename` used `PathUtils.equalsIgnoreSchemeIfOneIsS3`, which deliberately treats an s3-schemed path equal to the same path with a different/absent scheme. **ACTION**: add a NEW package-private helper to `HiveWriteUtils` — `equalsIgnoreSchemeIfOneIsS3(String,String)` — a byte-faithful port of HEAD `PathUtils.equalsIgnoreSchemeIfOneIsS3` (find it: `fe/fe-core/.../foundation/util/PathUtils.java` or wherever HEAD defines it), add a unit test for it in `HiveWriteUtilsTest`, and use it for the committer's `needRename`/`needRename`-style checks (`prepareInsertExistingTable`/`prepareAddPartition`/`prepareInsertExistPartition`). Keep `pathsEqual` for exact-equality uses only. +- **GAP-12 RESOLVED — no plugin partition-name parser exists.** No `HiveUtil.toPartitionValues`/`convertToNamePartitionMap` in `fe-connector-hive`. **ACTION**: port the pure `col=val/col2=val2` → `List` (values in order) split as a package-private static helper (in `HiveWriteUtils` or a private method in the txn). Byte-faithful to HEAD `HiveUtil.toPartitionValues` (URL-decode each `=`-split value as HEAD does — verify HEAD uses `FileUtils.unescapePathName`/`MetaStoreUtils`). Add a small unit test. +- **D6 completeMultipartUpload — MAP OVERLOAD CONFIRMED (port §3.9c verbatim).** `ObjFileSystem.completeMultipartUpload(String remotePath, String uploadId, Map etags) throws IOException` EXISTS (converts to sorted `UploadPartResult` list internally). `TS3MPUPendingUpload.getEtags()` = thrift `map` = `Map`. HEAD's block (HMSTransaction ~1876-1893) ALREADY calls `objFs.completeMultipartUpload(remotePath, s3mpu.getUploadId(), s3mpu.getEtags())` + catches `java.io.IOException` — copy verbatim; ONLY change how `objFs` is obtained (build plugin FS from `context.getStorageProperties()` instead of `((SpiSwitchingFileSystem)fs).forPath(path)`). +- **D6 abort CONFIRMED**: `objFs.getObjStorage().abortMultipartUpload(String remotePath, String uploadId) throws IOException` (`ObjStorage.abortMultipartUpload`). `getObjStorage()` returns `ObjStorage`. +- **D6 FS-build API CONFIRMED**: `StorageProperties.kind()` returns `StorageKind`; `StorageKind.OBJECT_STORAGE` exists. `ConnectorContext.getStorageProperties()` returns `List` (default method, line ~292). `FileSystemProvider` (`org.apache.doris.filesystem.spi`, `interface FileSystemProvider

    extends PluginFactory`): `boolean supports(Map properties)` + `default FileSystem create(Map properties) throws IOException` (also a typed `create(P)`; use the `Map` one). Recipe: `ServiceLoader.load(FileSystemProvider.class)` → first `p.supports(objSp.rawProperties())` → `p.create(objSp.rawProperties())` → cast to `ObjFileSystem`. **ISOLATE behind one method `resolveObjectStoreFileSystem(StorageProperties)` (swappable + test-injectable)** — production ServiceLoader discovery of directory-loaded providers is a cutover-time concern (§8/R3), unit tests inject a fake, batch is dormant. +- **auth CONFIRMED**: `ConnectorContext.executeAuthenticated(Callable task) throws Exception` (default method, line ~94). Wrap each fs/rename/MPU task body: `context.executeAuthenticated(() -> { ...; return null; })` inside `try { } catch (Exception e) { ... }`. +- **iceberg template ctor CONFIRMED**: `IcebergConnectorTransaction(long transactionId, IcebergCatalogOps catalogOps, ConnectorContext context)`; uses `context.executeAuthenticated(() -> {...})` for table load; `close()` at ~1114. Hive analogue: `HiveConnectorTransaction(long, HmsClient, ConnectorContext)`. +- **beginTransaction wiring CONFIRMED**: `HiveConnectorMetadata` already holds `private final HmsClient hmsClient;` + `private final ConnectorContext context;`.

Locked decisions (do not re-litigate during implementation) + +| # | Decision | Rationale | +|---|---|---| +| **D1** | **Four-class split**, mirroring iceberg: `HiveConnectorTransaction implements ConnectorTransaction` + immutable `HiveWriteContext` + `HiveWritePlanProvider implements ConnectorWritePlanProvider` + one-line `HiveConnectorMetadata.beginTransaction`. **`planWrite` is NOT in the metadata.** | Corrects the spec (which said planWrite is in metadata). Iceberg `planWrite` lives in `IcebergWritePlanProvider`, metadata has only the begin factory. | +| **D2** | `profileLabel()` returns **`"HMS"`**. | `TransactionType.HMS` already exists in fe-core → **zero fe-core change**. `"HIVE"` would fall back to `UNKNOWN` or force a fe-core enum edit. | +| **D3** | `getUpdateCnt()` = **sum of `THivePartitionUpdate.getRowCount()`**. | Preserves legacy `HMSTransaction.getUpdateCnt()` behavior (migration-faithful). | +| **D4** | **Drop query profiling** in the plugin (no `ConnectContext` / `SummaryProfile`). `queryId` arrives via `HiveWriteContext`. Collapse each `wrapper*WithProfileSummary` to its plain body. | Iceberg dropped profiling identically. Removes the `org.apache.doris.qe` / `common.profile` coupling (#1) with zero behavior loss beyond profile timings. | +| **D5** | **Auth**: metastore calls are auth'd **for free** inside `ThriftHmsClient.execute()` (it already does `doAs` + system-CL TCCL pin). Only the **plugin-owned async fs/rename/MPU tasks** must each be wrapped in `context.executeAuthenticated`. **No JVM-wide worker-pool primer** (hive fans work onto its *own* pool, not a shared SDK pool — unlike iceberg's `ThreadPools.getWorkerPool()`). | Recon: iceberg's `pinIcebergWorkerPoolToPluginClassLoader` is SDK-specific. Per-task wrap is correct for hive. See coupling #3. | +| **D6** | **MPU downcast**: replace `((SpiSwitchingFileSystem) fs).forPath(path)` with a **plugin-side `fe-filesystem-spi` FileSystem** built from `context.getStorageProperties()`; keep the `instanceof ObjFileSystem` guard + `objFs.completeMultipartUpload` (complete) and `objFs.getObjStorage().abortMultipartUpload` (abort). | `SpiSwitchingFileSystem` is fe-core; `ObjFileSystem`/`ObjStorage` are plugin-visible (`org.apache.doris.filesystem.spi`). | +| **D7** | full-ACID **write** hard-reject in the transaction begin-guard; full-ACID **read** detected + `FullAcidFileFilter` + delete-delta merge. | OQ-ACID-WRITE. Do not conflate "reject full-acid write" with "skip full-acid read". | +| **D8** | `isTransactional` / `isFullAcid` derived **plugin-side** from `HiveTableHandle.getTableParameters()` (the raw HMS props: `transactional`, `transactional_properties`). | fe-core parses no properties (project rule). Mirrors `HMSExternalTable.isHiveTransactionalTable/isFullAcidTable`. | +| **D9** | `rollback()` **deletes staging files + aborts MPU** (port legacy `pruneAndDeleteStagingDirectories` + `abortMultiUploads`). NOT a no-op. | Hive writes data files to staging **before** commit (unlike iceberg's manifest-only staging). Genuine divergence from the iceberg template. | +| **D10** | The transaction uses the **plugin `HmsClient` SPI**, not fe-core `HiveMetadataOps`/`HMSCachedClient`. Write-primitive DTOs are plugin-side (`connector-api` + JDK types). | Keeps the plugin fe-core-free. `HmsClient` is the metastore seam. | +| **D11** | thrift `THivePartitionUpdate` (commit fragment) + `THiveTableSink` / `TDataSinkType.HIVE_TABLE_SINK` (sink) travel with the plugin as-is. | The shared thrift module is already compile-visible to `fe-connector-hive` (`HiveScanRange` imports `org.apache.doris.thrift.*`). Verified: `HIVE_TABLE_SINK=13`, structs at `DataSinks.thrift:365/393`. | +| **D12** | Read-txn primitives are a **strict subset** of the write-primitive HmsClient surface and are used **only by the read side** (`HMSTransaction` never calls `openTxn/commitTxn/getValidWriteIds`). Surface all HmsClient primitives once (read + write) in this batch. | Recon-confirmed by grep. Avoids double-surfacing. | + +--- + +## 3.

All §7 TODO items landed; verified: fe-connector-api 58 tests, fe-core `PluginDrivenScanNode*` 76 tests (incl. new `PluginDrivenScanNodeScanProviderSelectionTest`), checkstyle 0 (api + core), import-gate clean. Fixed 2 existing tests (`DeleteFilesTest`/`BatchModeTest`) to stub the arg overload (bare Mockito mocks don't run the real default). + +## 1. Goal / Non-goals +**Goal**: give fe-core a connector-agnostic way to pick a *different* `ConnectorScanPlanProvider` **per table** within one catalog, so that after the flip a single heterogeneous `hms` catalog (plain-hive + iceberg-on-HMS + hudi-on-HMS, all under one `PluginDrivenExternalCatalog` wrapping one gateway connector) can route each table to the right scanner. Locked decision D-020 ("per-table SPI provider; the hms gateway connector delegates to `-iceberg`/`-hudi`"). + +**Non-goals (deferred, explicitly out of this sub-batch)**: +- The hive gateway's actual delegation to iceberg/hudi providers (module-dependency restructure, format probe) → sub-batches B (iceberg-on-HMS) / C (hudi). +- Threading `tableFormatType` from `ConnectorTableSchema` into `PluginDrivenSchemaCacheValue` → deferred to the consumer that needs it (BE `TTableFormatFileDesc`, capability derivation, MTMV — sub-batches B/E). The seam does **not** need it (see §3). +- Any change to write/DDL/stats/MVCC routing. +- Any GSON / flip / delete work. + +## 2. Why a selection seam is *necessary* (not just internal dispatch) — the decisive finding +`ConnectorScanPlanProvider.planScan(session, handle, …)` **does** receive the `ConnectorTableHandle`, so one could imagine the gateway returning a single "dispatching" provider from the existing no-arg `getScanPlanProvider()` that routes inside `planScan` by inspecting the handle. **This does not work**, because: +- Providers are built **fresh per call** and are **stateless** (see the "fresh provider per call" comments in `IcebergScanPlanProvider:159`, `PaimonScanPlanProvider:172`). +- Several `ConnectorScanPlanProvider` methods **do not carry the handle** — notably `appendExplainInfo(output, prefix, props)` (called at `PluginDrivenScanNode:375`) and the node-properties/streaming-estimate paths. A fresh, stateless dispatching provider has no handle for those methods and cannot know which sub-provider to use. + +Therefore the selection **must happen at provider-acquisition time**: fe-core asks the connector for the provider **for this handle**, and the connector returns a provider already bound to the correct sub-provider (so even the handle-less methods are routed correctly). This is exactly D-020. + +**Trino parallel**: Trino runs one connector per format (`hive`/`iceberg`/`hudi`) and uses *table redirection* — the hive connector reports "this table lives in catalog X"; the engine **resolves the redirect once at analysis time** and re-binds all subsequent operations to the iceberg connector. We resolve once at provider-acquisition time and bind the provider — same "resolve once, then all ops follow" shape, kept inside one gateway connector instead of across catalogs (Doris exposes one `hms` catalog historically; a cross-catalog redirect would be a visible, breaking change). + +## 3. SPI shape — the one real decision +Add a **per-handle overload** that defaults to today's behavior. Two candidate homes: + +- **(Rec) `Connector.getScanPlanProvider(ConnectorTableHandle handle)`** — sits next to the existing no-arg `Connector.getScanPlanProvider()` (`Connector.java:46`, returns `null` by default). Default: `return getScanPlanProvider();`. The gateway connector owns its sub-connectors (iceberg/hudi) as fields and returns the right one's provider. **Smallest fe-core change**: `PluginDrivenScanNode` already holds `connector` + `currentHandle`; no metadata plumbing. +- (Alt) `ConnectorMetadata.getScanPlanProvider(ConnectorSession, ConnectorTableHandle)` — groups with the other per-handle methods (`getTableStatistics(handle)`, `applySnapshot(handle)`). But provider-selection is a connector-structural concern (which sub-connector), not a metadata-transaction op; the node would fetch metadata per call. + +**The discriminator (how a connector maps a handle → sub-provider) is intentionally NOT in the SPI**: the handle is the connector's own opaque subclass, so the gateway carries whatever it needs (a DLA/format enum) and casts it internally. fe-core never branches on format (iron rule preserved). → the enum-vs-string-vs-capability discriminator question is a **B/C connector-internal** decision, not an A decision. + +## 4. fe-core change (localized to `PluginDrivenScanNode`) +- Replace the **11** uniform call sites `connector.getScanPlanProvider()` (lines 375, 475, 524, 885, 898, 1042, 1174, 1260, 1313, 1328, 1410) with a single private helper `resolveScanProvider()` → `connector.getScanPlanProvider(currentHandle)`. +- Null-tolerance preserved (default overload → no-arg → may be `null`; existing null checks unchanged, e.g. the `:1042` "may be null for connectors without scan capability" path). +- `currentHandle` is the field already set in the ctor (from `create()` `resolveConnectorTableHandle`, `:191`) and updated by filter/projection pushdown — so per-handle selection uses the same handle the rest of the scan already uses. No new state. +- **Zero behavior change for every existing connector** (es/jdbc/trino/maxcompute/paimon/iceberg/hive): none overrides the overload → all fall through to no-arg → byte-identical. + +## 5. Test plan (unit, no Mockito on connector side; fe-core may use its infra) +- `PluginDrivenScanNode` contract test with a **fake multi-provider connector**: `getScanPlanProvider(handle)` returns provider-A for handle-type-1 and provider-B for handle-type-2; assert the node's `planScan`/explain path uses the handle-matched provider. Assert a connector that does **not** override the overload falls back to the no-arg provider (byte-identical), and that a null no-arg provider still yields the existing null-safe behavior. +- Regression: existing `PluginDrivenScanNode*Test` (verbose-explain etc.) stays green (proves inertness). + +## 6. Risks +- **R1 (low)**: missing one of the 11 call sites → that path stays connector-level (single provider) while others are per-handle → a heterogeneous table could mis-route on that path only. Mitigation: the single-helper refactor + a grep assertion that no `connector.getScanPlanProvider()` (no-arg) remains in `PluginDrivenScanNode`. +- **R2 (low)**: `currentHandle` is mutated by pushdown (`applyFilter`/`applyProjection`); confirm the provider identity does not need to be stable across a mutation within one scan (it does not — the gateway keys on table format, which pushdown does not change). Documented in the helper. +- No SPI compatibility risk: additive default method; no existing connector or test implements it. + +## 7. Ordered TODO +1. Add `Connector.getScanPlanProvider(ConnectorTableHandle handle)` default (`return getScanPlanProvider();`) + javadoc stating the acquisition-time-binding contract (§2) and that the default keeps single-provider behavior. +2. `PluginDrivenScanNode`: private `resolveScanProvider()` helper; swap all 11 sites; keep null-tolerance. +3. Fake multi-provider connector + contract test; run existing PluginDrivenScanNode tests. +4. Build `fe-connector-api` (`-am`) + `fe-core`; checkstyle 0 (api + core, no `-am`); `check-connector-imports.sh` clean. +5. Update HANDOFF + this doc; commit (this seam is a standalone, dormant, additive commit — safe to land independently, unlike the P7.3 atomic batch). + +## 8. Open decision for user sign-off (this sub-batch) +- **Scope**: pure seam + fake-connector test (dormant), vs. seam + first real iceberg-on-HMS delegation folded in (bigger, pulls module-dep restructure forward). +- **SPI home**: `Connector` overload (rec) vs `ConnectorMetadata`. +(Discriminator shape, tableFormatType threading, GSON MVCC conflict, per-column stats → later sub-batches.)

的行因此少给值 → fe-core `PluginDrivenMvccExternalTable.listLatestPartitions:277` 的 `Preconditions.checkState(connectorValues.size() == types.size(), ...)` 抛出。 +- **两种形态同一机制**：部分值（`'year=2024/month=1'` 2 值 vs 3 列，来自 `ADD PARTITION KEY day`）与零值（原表 UNPARTITIONED，spec-0 循环 0 次 → name `''`）。`IcebergPartitionUtils.java:632` 的 `table.spec().isUnpartitioned()` 早退**救不了**后者——它测的是当前 spec。 +- **为何走到这条路**：6 张表都过不了 `isValidRelatedTable` (`:682-701`，要求每个 spec 恰好 1 个 year/month/day/hour transform) → `buildMvccPartitionView` 返回 `unpartitioned()` (`:533-535`) → `getMvccPartitionView` 恒 `Optional.of(...)`

行之上已有的降级先例（dropped source column → 返回空 list，已有单测 `IcebergPartitionUtilsTest:956`），当固定 arity 的 LIST 展示无法表达异构 arity 分区时**降级为 UNPARTITIONED（空 list）**——正是 master 的行为。 + +> **✅ 采纳 fix-soundness reviewer

会再过滤一次（`fromRemoteColumnName` → `byName.get(...)` → `col != null`），所以 `types.size() <= currentArity`。**残留漏洞**：分区源是**嵌套字段**时 `findField != null`（计入 currentNames）但 `source.name()` 是叶子名、匹配不到任何顶层 FE 列 → fe-core 丢弃 → 当前 spec 的行也不会触发降级 → **checkState 仍会抛**。6 个失败表的分区源都是顶层列，故不阻塞，但这个洞必须记录或立 issue，不要用假理由盖掉。 + +**否决方案**：① 放松/删除 fe-core checkState（会把 spec-evolution 的源特有知识塞进通用层，违反 connector-agnostic 铁律，且撤销对 hive/paimon/hudi 的 fail-loud 保护）；② 用 `partitionValueNullFlags` 补 NULL（**正确性陷阱**：编码"老文件 day=NULL"这个**假事实**，仅因当前 `getPartitionType` 返回 UNPARTITIONED 而暂时无害，是定时炸弹）。 + +### 风险 & 置信度 +**LOW，且严格收窄。** 输出仅用于展示/治理（`selectedPartitionNum` + `partition_num` block-rule），从不是读取集合。关键论证（比原 RCA 更强）：**被改变行为的表 == 今天必然抛异常的表**，所以不可能命中那 550 个通过的用例。已验证 4 个受影响 suite 的 .out 里**没有** `partition=N/M` 断言；且 `IcebergScanPlanProvider.java:297-309` 的 `scannedPartitionCount` 从 scan range 的 `getScannedPartitionKey()` 独立构造，`PluginDrivenScanNode.java:330-333` 优先采用它 ⇒ **降级后 `selectedPartitionNum` 依然存活**（原 RCA 的

`__DORIS_GLOBAL_ROWID_COL__*`，`colUniqueId = Integer.MAX_VALUE` → guard 的 key 选择（`PluginDrivenScanNode.java:937-939`）走 field-id 分支 → 任何 pinned schema 都不含 `Integer.MAX_VALUE` → 抛。该列由 connector reader 合成、根本不是表列，`PluginDrivenScanNode` **已在另外两处排除它**（`:559` `classifyColumn`、`:1019` `hasTopnLazyMaterializeSlot`），guard 忘了。 + +**fe.audit.log 2×2 阶乘证明**：`FOR TIME AS OF` 无 lazy-mat → EOF；`order by ...

`rowIdColumnIsExcludedNoThrow`（bound = [id@1, `__DORIS_GLOBAL_ROWID_COL__t`@Integer.MAX_VALUE]，pinned = [id@1] → assertDoesNotThrow），否则盲区会复发。 + +### 触发器 2 — sys-table pin（`paimon_system_table`） +`pinMvccSnapshot:885` → `resolveSysTableSnapshotPin():1044` 只判 `instanceof PluginDrivenSysExternalTable` + `source instanceof MvccTable`，**从不查 `sysTableSupportsTimeTravel()`**，于是给 paimon 也拿了**源表**的 pin；`PluginDrivenMvccExternalTable.loadSnapshot:394-405` 的 point-in-time 分支返回**非 null 的源表 pinnedSchema**；guard 拿 sys 表的列（`snapshot_id`…）去比源表 schema → 必然抛。异常再被 `getOrLoadPropertiesResult:1742` 包成 `RuntimeException("Failed to pin MVCC snapshot for plugin-driven scan")` → 客户端看不到真因 → 用例断言的 `system tables do not support time travel` 不匹配。 + +**注意**：guard **确实存在且正确**（`checkSysTableScanConstraints:1073`，消息在 `:1083`/`:1087`），只是**不可达**——它只被 `getSplits:1106` / `startSplit:1454` / `:1551` 调用，全在 init 之后。代码注释 `:896-897`（"sys-table scan carries a null pinnedSchema -> no-op"）和 `:1039`（"checkSysTableScanConstraints already rejects that case"）**都被证伪**，必须一并改掉。 + +> **🔴 采纳 fix-soundness reviewer 的推翻，改用能力位门控（不是原 RCA 的 assert carve-out）** +> +> **文件/位置**：`PluginDrivenScanNode.java:1044` `resolveSysTableSnapshotPin()`，在取 source pin 之前插入： +> ```java +> if (!sysTableSupportsTimeTravel()) { +> return Optional.empty(); +> } +> ``` +> **为什么比 carve-out 好**：paimon 走这里根本不再调 `loadSnapshot` ⇒ ①不触发 guard ②不触发 `loadSnapshot:368` 的 `notFoundMessage` **RuntimeException**（该异常**不被** `:1741` 的 `catch (UserException e)` 拦截，会带着 paimon 自己的文案冒到客户端）③省掉一次无用的 `getTableSchema` 往返。三个 block（`FOR VERSION`/`FOR TIME`/`@incr`）都**数据无关地**拿到期望文案。原 RCA 的 carve-out 让 block 2（`FOR TIME AS OF '2024-07-11 16:01:57.425'`）的成败取决于 fixture 里是否存在 at-or-before 快照——静态分析无法判定，是掷硬币。同样是 connector-agnostic（分支在通用 fe-core 类型 + 既有能力 SPI 上，不按源名）。iceberg（`IcebergScanPlanProvider.supportsSystemTableTimeTravel():340-341` = true）不受影响，仍正常拿 pin。 +> +> **refute-lens 的补充（支持任一方案可行）**：`PaimonConnectorMetadata.java:715-720` `applySnapshot` 对 `paimonHandle.isSystemTable()` 直接短路返回，**不会抛**，所以跳过 guard 后 init 一定能走完到 `checkSysTableScanConstraints`。原 RCA 未证的一环由此闭合。 + +**测试**：`paimon_system_table.groovy` 在本分支**被改过**（`buildlog.txt:5766`），但 diff 显示三处期望只是**放宽**（`Paimon system tables do not support time travel` → `system tables do not support time travel`）以对齐 connector-agnostic 文案。期望严格弱于 master ⇒ **排除**陈旧用例假设，坐实产品 bug。 + +### 触发器 3 — version-blind schema binding（`iceberg_query_tag_branch`）🔴 **未解决，需产品决策** +`SELECT t1.c1, t2.c1 FROM tag_branch_table@tag(t1) t1 JOIN tag_branch_table@tag(t2) t2` → `StatementContext.getSnapshot(TableIf)`（version-**blind**，`:1015-1032`）命中自己文档的 case (3)"两个非默认版本、无默认 → 歧义 → 返回 empty" → `PluginDrivenMvccExternalTable.getSchemaCacheValue:494-503` 回退 **LATEST {c1,c2,c3}**；`LogicalFileScan` 非 `OutputPrunable`（`ColumnPruning` 只裁剪 `OutputPrunable`）⇒ scan tuple 携带未裁剪的 c1,c2,c3；而 `pinMvccSnapshot:873-874` 的 version-**aware** 查找正确解析 tag t1 → `{c1}`（`run11.sql:14` 建 t2 早于 `:16` 加 c2）→ guard 在 c2 上抛。 + +**guard 报的 c2 就是直接证据**：查询根本没引用 c2（原 RCA 的 open question #2 可关闭，无需 EXPLAIN VERBOSE）。 + +**🔴 两位 reviewer 一致推翻原 RCA 的 "Change 2"**（放宽为"只查 field-id 名字冲突"）： +1. 其核心论据 **`iceberg_query_tag_branch.out` 的 `-- !branch_1 --` = `1 \N \N` 证明 absent→NULL 是被认可语义** —— **是混淆**。BRANCH pin 经 branch-aware handle 解析（`PluginDrivenMvccExternalTable.java:387-396`），iceberg branch schema = latest = `{c1,c2,c3}`，**没有任何列 absent**；那些 NULL 来自**数据文件**的普通 schema-evolution 填充。branch 路径根本没运行过 guard，无法为 tag 路径背书。 +2. `TEST EDITS: none` **是假的**：会打挂 4 个现有单测——`fieldIdRenumberBetweenBoundAndScannedVersionThrows:52`、`columnAddedAfterScannedVersionThrows:66`（**字面就是 case 3，被断言为应当抛**）、`nameMissWhenNoFieldIdThrows:77`、`fieldIdStableRenameResolvesByIdNoThrow:88`（Change 2 会**新增**对 benign rename 的误拒，与该类 javadoc `:919-921` "a rename that keeps the id is fine" 直接冲突）。 +3. 其 `if (bound.getUniqueId() < 0) continue;` 会**整体关闭 paimon 的 guard**（name-matched connector），rename 从 fail-loud 退化为静默读 NULL。 +4. 其 fix_risk 宣称"仍能捕获 dropped-then-re-added 的 field-id renumber"——**假的**：单测 `:52` 的 renumber 场景同名，无名字冲突，Change 2 静默放行 ⇒ **它什么都捕不到**。 + +**且这是本分支自造的 skew**：上游 `fbef303da5f:StatementContext.java:730-736` 是 `return Optional.ofNullable(snapshots.get(new MvccTableInfo(tableIf)))`——单 key、有 pin 时**从不返回 empty**。version-aware key + "ambiguous → empty" 是本分支 `442a1081e6d` 引入的。由于 t1 和 t2 schema 都是 `{c1}`，**上游绑定 `{c1}`，这条查询本来零 skew**。所以 guard 只是信使，真缺陷在 binding。 + +`.out` **不要改**：`iceberg_query_tag_branch.groovy/.out` 与 `run11.sql` 与上游 `fbef303da5f`(#51272) **字节相同**，`1 1` 是上游验证过的正确答案。 + +**三个选项（需用户拍板）**： +- **C1（推荐，恢复上游 parity 且保住 guard 的牙）**：修 binding——让 `StatementContext.getSnapshot(TableIf):1015-1032` 对同表多版本不再回退 LATEST（恢复上游行为返回其中一个 pinned entry），或做 per-reference version-aware binding（即已跟踪的 **D-MVCC-VERSION-SCHEMA**）。skew 真消失，guard 自然不响，`1 1` 由构造得出而非侥幸。 +- **C2**：暂接受该用例红，annotate/disable 单个 case，等 C1。 +- **C3（原 RCA 方向，不推荐）**：明确决定"bound field-id 不在 pinned schema 中"合法。若选它，**必须**同时改写/删除上述 4 个单测，**不得**用 `uniqueId<0` 一刀切（要保住 paimon name check），且需重新论证（branch_1 论据作废）。此举**部分推翻 2026-07-13 已签字的 "throw for now" 决策**，须用户同意。 + +### ❗仍未证实（B 整体） +- 无论 C1/C2/C3，**没人能静态证明**这 3 个 iceberg 用例修完变绿。C3 额外依赖"connector 的 projection push-down 能容忍请求一个在该快照

是否可能经同一 fe-core LIST 路径产生异构 arity**。checkState 是通用的、对它们同样会触发。相信它们无此类 spec-evolution 概念，但**未证明**。 +4. **B/C3 的关键未知**：若放宽 guard，connector 的 projection push-down 是否容忍"请求一个在该快照 schema 中不存在的列"（vs NPE / field not found）—— **无人验证过**，这是偏好 C1 的实质理由。 +5. **C 的修复充分性未证**：只做了三个类的 depth-1 引用闭包，不是建表全路径的传递闭包。用例过了 :44 还要建 test01–test05。只有真跑 HMS 才知道。 +6. **C 的顺序依赖**：`MetaStoreUtils.` 中毒是 loader 生命周期级的，`test_paimon_catalog` 同用 hms 却通过（未查明原因）⇒ 该失败在别的 build 里可能**看起来像 flake**。不要据此隔离。 +7. **F1 是否为本分支回归 未知**（见 P2 #7）。 +8. **F 的 scope 未界定**：`inferFileFormatFromDataFiles` 只是**恰好会 catch** 的那个调用点。从未 pin 的 `bindDataSink → planWrite` 线程可达的其它 plan-time iceberg S3/FileIO 调用同样暴露，且会**直接抛而非被吞**——**未枚举**。 +9. **`DorisConnectorException` ×253 未逐条调查**（token 预算）。在迁移分支上这是"SPI 方法未实现"的典型签名，且不被 13 个已知失败解释。**这是第二个被吞 bug 最可能的藏身处**，建议照 §F 的方法扫其 top stack frame。（`UnsupportedOperationException ×370` 已被 reviewer 解决 = 全部是 F1。） +10. **E**：无非-ASAN 对照；未查 V1 reader 的内存画像；mute 的 provenance 需 TeamCity API。 +11. **iceberg-rest 的 10 条 CommitFailedException + 2 条 ValidationException** 未与 17:31–17:36 的 iceberg 失败逐行时间关联。它们是应用级 REST 响应（症状），不改变任何结论，但 iceberg 集群的 owner 应确认它们是那些失败的**后果**而非独立信号。 +12. **工具告警（值得记录）**：本机的 `rg` 存在**静默改写匹配文本**的行为（把 `planWrite` 渲染成 `n`、`ConnectorWritePlanProvider` 渲染成 `ln`，并对普通 `grep` 能答的 suites 检索返回空）。**本报告中任何来自 rg 的"零命中"结论都不可信**；载重的否定结论已用 `grep` 复核。后续排查请优先 `grep`。 +13. **本次运行 13 个失败中，本报告的 A/B/C/D 共解释 12 个，E 解释第 13 个（muted）。F 解释 0 个** —— 它是被绿色测试掩盖的独立缺陷，不应作为 996541 的根因呈现（原 cross-cutting RCA 的 `verdict=product-code-bug` / `confidence=high` 顶层字段在这一点上是范畴错误，已在此更正）。 \

`4f8b35c2126` 自陈 `未证：e2e 未跑` —— 只靠单测合入，而单测无一覆盖计划路径上的 hidden-column 门。 + +**修法**：补 1-arg override，两个 arity 共走私有 `appendSyntheticWriteColumns()`；snapshot 只喂 base schema 读取（合成写列是 request-scoped 非

本身）。**先前修复不完整**：`270bd11f4da`。 + +**机制**：sys-table 的 pin 按构造从**源表**解析（`resolveSysTableSnapshotPin`），`pinnedSchema` = 源表 `{id,name}`，而 `desc.getSlots()` = sys 表 `{file_path,pos,row,spec_id,delete_file_path}`。两者比较**永远无法 resolve** ⇒ 抛假的 "multiple versions"，被 `getOrLoadPropertiesResult` 重新包装成 `Failed to pin MVCC snapshot for plugin-driven scan`（wrapper 盖住了真错）。 + +**判据（自然实验）**：runner log 68904-68924，09:45:20 同一张 sys 表 `desc` / `count(*)` / `where pos>=0` / `where spec_id=0` / `where delete_file_path is not null` / `select \`row\`` **全部成功**，只有 09:45:21.314 的 `for version as of` 失败 ⇒ **pin 是唯一变量**，排除 TCCL / schema-load / timeout。 + +**⚠️ 这不是重复修，是延期理由被证伪**：`270bd11f4da` 碰过这段代码，**故意只修 paimon 半边**，留 KNOWN GAP 注释（逐字预言了本次失败），理由「iceberg sys-table 时间旅行今天零 e2e 覆盖」。**该前提当时即为假** —— e2e 是上游 `0814e49bea7`(#65135) 的 `test_iceberg_position_deletes_sys_table.groovy:549-560`，早于本分支。本轮就是那次待跑的验证到来。代码把自己的 bug 写在注释里了。 +（细节：该测试经 2026-07-15 rebase 进来，拓扑上早于 guard、时间上晚于 guard ⇒ 测试与 guard 很可能从未在同一次绿跑中共存 ⇒ **首次观测到的潜伏破损**，非二次破坏。） + +**修法**：guard 第三参 name → `TableIf`，在 null-pinnedSchema no-op 旁加 `table instanceof PluginDrivenSysExternalTable` 排除；删除过期 KNOWN GAP 段。**拓宽签名而非在调用点判**，是为了让排除可被静态 harness 变异验证（条件若留在 private `pinMvccSnapshot()` 则测不到）。 + +**安全性**：`PluginDrivenSysExternalTable`(:41) 与 `PluginDrivenMvccExternalTable`(:85) 是**兄弟类** ⇒ 正常 MVCC

`sysTableIsExcludedNoThrow` 红；把排除放宽到共同父类 `PluginDrivenExternalTable` → **5 红**（含新增的 `normalMvccTableWithSameShapeStillThrows`）。 +**两个 vacuity 陷阱已钉进注释**（初稿踩了第二个、以错误理由通过）：pinnedSchema 必须非 null；bound 列必须 `uniqueId == -1` —— 若给 sys 列与源表碰撞的 field-id（`file_path@1` vs `id@1`）会**按 field-id resolve 成功而永不抛**，测试即失效。按 name 匹配也才是真实情况（CI 正是在 'file_path' 上按 name 撞 `{id,name}` 而抛）。 + +**未证**：去掉抛出只解开 init。真正绿还需 iceberg 连接器 `$position_deletes` planner 认这个 pin（`doPlanPositionDeletesSystemTableScan` 读 `handle.hasSnapshotPin()`，由 `IcebergConnectorMetadata.applySnapshot` 喂）—— 已 trace 未执行。suite 后半段 `:562-568`（源表跨 ADD COLUMN 时间旅行）在本分支从未跑过。**可能需要第二轮**。 + +**故意不打包进来**：`PluginDrivenScanNode:1213`（`scannedPartitionCount` 在 `$position_deletes` 上触发，HANDOFF gap ⑤）。同文件同 suite，但与 2026-07-13 `selectedPartitionNum`

读取。潜伏一个月无害 —— fe-core 的 `hive-catalog-shade` 经 parent loader 兜底；`9a10ece30c8` 删掉那个 jar ⇒ **两个 loader 都取不到** ⇒ paimon `RetryingMetaStoreClientFactory` 反射逐个试 `getProxy(...)` 全部 `NoClassDefFoundError` →

`ConnectorPartitionInfo`（`fe-connector-api`）上加一个 `List orderedPartitionValues`（渲染后的有序值， +与现有 `partitionValueNullFlags` 位对齐）。fe-core 直接 zip「连接器值 + 类型 + 空标志」，**零解析**，删掉 `HiveUtil`/`FileUtils` 依赖。 +- 4 个连接器各补一行传已算好的值：hive `HiveConnectorMetadata:1108`、paimon `:1078`、iceberg `IcebergPartitionUtils:545`、hudi `HudiConnectorMetadata:734`。 +- **不复用现有** `ConnectorPartitionInfo.getPartitionValues()`（Map）：paimon 在该 Map 存的是**未渲染的原始 spec**（DATE 存 epoch-int， + `PaimonConnectorMetadata:1067`）且该 Map 是 paimon 自身扫描规划的输入（`:971` 在读它），改写会扰动 paimon

Splitting maps `forLocation` (= `forPath` → `LocationPath.of` + `FileSystemFactory.getFileSystem`, i.e. resolution + FS *construction*, **no I/O**) to the old `FileSystem.get` SYSTEMIC boundary, and `resolved.list` (= `DFSFileSystem.list` → `getHadoopFs` → the actual Hadoop `FileSystem.get` + `listStatusIterator`) to the old `listStatus` LOCAL boundary. **Residual (accepted, documented)**: bad-namenode-host / connect failures surface at `list` = LOCAL/skippable. Old code's classification of these was Hadoop-version-dependent (connect is lazy at first RPC), so this is not a clear regression; only the *deterministic scheme-not-registered* class is force-classified systemic (via `isSystemicResolutionFailure`). + +### D3 — filter + field parity +- `resolved.listFiles(loc)` = non-recursive, directories excluded (contract; default impl iterates `list()` filtering `isDirectory`) — matches old `listStatus` + `!isDirectory` filter. +- `_`/`.` filter applied on `FileEntry.name()` (last path segment) — matches old `status.getPath().getName()` prefix check. +- Zero-length files kept (splitter skips size==0; estimate adds 0) — `listFiles` returns them. +- Path string: `FileEntry.location().uri()` == `HdfsFileIterator`'s `Location.of(status.getPath().toString())` == old `status.getPath().toString()`. **`Path.toString()`, not `toUri().toString()`** → no `%3A` double-encoding regression for hive timestamp partition dirs. `length()`/`modificationTime()` map 1:1. + +### D4 — null-FS guard (fail loud, systemic) +`context.getFileSystem(session)` returns `null` only for a catalog with no storage (HIVEFS-3). A plain-hive catalog always has storage, but guard defensively: `null` FS → loud `DorisConnectorException` (systemic — affects every partition). For the estimate path this is caught by `estimateDataSize`'s `catch (RuntimeException) → -1` (best-effort, unchanged); for scan / `listFileSizes` it fails the query loud (Rule 12), never a silent empty scan. + +### D5 — plumbing +- `HiveScanPlanProvider`: add `ConnectorContext context` ctor arg (3rd, mirroring `HiveConnectorMetadata`; HiveConnector already holds it). Resolve `FileSystem fs = context.getFileSystem(session)` once in `planScan` / `planScanForPartitionBatch`, thread `fs` down to `listAndSplitFiles` → `listDataFiles`. `buildHadoopConf()` STAYS (still used by `planAcidScan:272`, HIVEFS-5) — so `HiveScanPlanProvider`'s `Configuration`/`FileStatus`/`FileSystem`/`Path` imports also STAY. It is no longer passed to `listAndSplitFiles`. In `planScanForPartitionBatch` (non-ACID only) the local `hadoopConf` becomes unused → drop that line. +- `HiveConnectorMetadata.listFileSizes`: resolve `FileSystem fs = context.getFileSystem(session)` under the EXISTING TCCL pin (ANALYZE path, loud by contract — resolving outside the estimate try is fine), pass to `listDataFiles`. +- `HiveConnectorMetadata.estimateDataSizeByListingFiles`: **[Minor-3]** resolve the FS INSIDE `estimateDataSize`'s protected region — pass `context.getFileSystem(session)` inside the size lambda (`location -> sumCachedFileSizes(hiveHandle, location, context.getFileSystem(session))`) so any throw from `getFileSystem` degrades to `-1` (statistics must not fail a query), not loud. `getFileSystem` is a cached field-return so per-location calls are cheap. +- `buildHadoopConf()` in `HiveConnectorMetadata` is used only by these two methods → remove both usages, the orphan private `buildHadoopConf()` method, AND **[Minor-2]** the now-unused `import org.apache.hadoop.conf.Configuration;` (checkstyle UnusedImports). `sumCachedFileSizes` param type flips `Configuration` → `org.apache.doris.filesystem.FileSystem`. + +### D6 — TCCL: keep the existing metadata-layer pins (rationale corrected per red-team) +`listFileSizes` / `estimateDataSizeByListingFiles` already pin the TCCL to the plugin loader (the stats thread is not pinned by fe-core). KEEP those pins. **Corrected rationale [Minor-4]**: the pin protects TCCL-*reflective* config-class loading (Hadoop `ServiceLoader`/`Configuration` reads the TCCL). The engine `DFSFileSystem`/`UserGroupInformation`/`SecurityUtil` classes are resolved by the **fe-filesystem-hdfs** plugin loader (their *defining* loader), not the hive-plugin loader the caller thread is pinned to — so the pin does not itself pick the hadoop copy. The construction path (first `forLocation` lazily builds a `DFSFileSystem` via `SpiSwitchingFileSystem` → `FileSystemFactory`) is **identical to what paimon/iceberg and every other engine FileSystem consumer already trigger in production today** — HIVEFS-4 adds no new classloader locus. `DFSFileSystem.getHadoopFs` additionally self-pins the fe-filesystem-hdfs loader for hdfs/viewfs around the actual `FileSystem.get` (the scheme-reflection point). Simple-auth `createRemoteUser` does no TCCL class reflection (benign); the kerberos-HDFS / custom `hadoop.security.dns` paths ride the same shared construction path already exercised. No NEW connector pin is added. + +## Test plan (connector module has NO Mockito → hand-written recording fake) + +**[Major-3] Full blast radius — 6 test files touch the changed seam/ctor; ALL must compile+pass for "build green":** +- New shared helper `FakeFileSystem` (package-private test class): a recording `org.apache.doris.filesystem.FileSystem` — `forLocation` returns `this` or throws (configurable); `list(Location)` returns a canned in-memory `FileIterator` over set `FileEntry`s or throws (configurable IOException, incl. an `UnsupportedFileSystemException` for the systemic case); all other methods `throw new UnsupportedOperationException`. Reused across the tests below. +- `HiveConnectorInvalidateTest`: replace the `CONF`/`@TempDir`+`Files.write` real-local-listing with a `FakeFileSystem` (list succeeds → leaves a cache entry; `size()` assertions unchanged). `listDataFiles(...,CONF)` → `listDataFiles(...,fakeFs)`. +- `HiveScanBatchModeTest`: `CountingLister.list(String,Configuration)` → `(String,FileSystem)`; `HiveScanPlanProvider` ctor gains `context` (a `new FakeConnectorContext()` — null FS is fine, the fake lister ignores it). +- `HiveConnectorMetadataFileListStatsTest`: `ThrowingFileListingCache.listDataFiles(...,Configuration)` override → `(...,FileSystem)`. +- `HiveReadTransactionTest`: `HiveScanPlanProvider` ctor gains `context` (ACID path; context unused for HIVEFS-4). + +Adapt `HiveFileListingCacheTest`: +- Replace the `CONF` constant + `CountingLister.list(String, Configuration)` with a `FileSystem`-typed seam; `CountingLister` becomes a `DirectoryLister` returning canned `HiveFileStatus` (unchanged — it is above the FS seam). +- Add a hand-written fake `org.apache.doris.filesystem.FileSystem` (a "RecordingFs") for the `listFromFileSystem`-level tests: override `forLocation` (return this or throw) + `listFiles` (return canned `FileEntry`s / throw `IOException`); all other methods throw `UnsupportedOperationException`. +- Rework the 4 real-lister tests to drive `listFromFileSystem(location, fakeFs)`: + - filter test: fake `listFiles` returns `[data1, data2, _SUCCESS, .hidden]` → assert only `data1,data2` (300 bytes) survive. + - `forLocation` throws IOException → assert loud `DorisConnectorException` (NOT `HiveDirectoryListingException`). + - `listFiles` throws IOException → assert skippable `HiveDirectoryListingException`. + - through-cache variants: assert type survives the cache boundary + `size()==0` (failure not cached). +- The scan-integration tests (`scanSkipsOnlyTheFailedPartition...`, `scanFailsLoudOnSystemicFilesystemFailure`, `scanProviderServesRepeatedScansFromTheCache`) update the `HiveScanPlanProvider` ctor to pass a fake `ConnectorContext` whose `getFileSystem` returns the fake FS (or null for a null-FS test). +- `estimateDataSizeIsServedFromTheCache`: `FakeConnectorContext.getFileSystem` returns the fake FS. +- Every assertion must be RED-able (revert the mutation → red). + +## Residual / deferred +- ACID `planAcidScan:272` + `HiveAcidUtil` bare Hadoop → HIVEFS-5. +- S3/OSS exception-split behavior: their FS construction may connect/validate creds eagerly (→ bad creds surface at `forLocation` = SYSTEMIC loud, which is *more* correct than old lazy behavior, not a regression).

IOException→loud）逐位一致**。故本步**不需要** HIVEFS-4 读扫描的 systemic-vs-local 分级 / `isSystemicResolutionFailure` 重分类（那是为"跳单坏分区"服务，ACID 从不跳）。 + +### 4. 为何直接传 switching FS（不先 `forLocation` 解具体 FS） +`getAcidState` 内所有路径（分区目录、base_/delta_ 子目录、`_metadata_acid` 文件）同属一个分区 location → 同 scheme/authority/`StorageProperties`。`SpiSwitchingFileSystem.list/exists` 内部各自 `forLocation`（按 `StorageProperties` 缓存、首次后命中）→ 路由到具体 FS 的**字面量 `list()`**。传 facade 让 util 签名最小（仅 Doris `FileSystem`，无 forLocation 步），且正确。（备选：在 planAcidScan 里 `forLocation` 解一次传具体 FS——亦可，但为无收益的额外步；ACID 不需要 forLocation 边界带来的失败分级。） + +### 5. 字面量列（list() 非 listFiles()） +per-scheme FS（`DFSFileSystem`/`S3CompatibleFileSystem`）override `listFiles` 为 **glob 感知**分支，会把含 `[`/`*`/`?` 的 location 当模式；老 `listStatus` 从不 glob 展开，而 hive location 可合法含这些字符（分区值）。故 `HiveAcidUtil` 一律 `fs.list(Location.of(x))`（`SpiSwitchingFileSystem.list`→具体 FS 字面量 `list`），过滤目录用 `FileEntry.isDirectory()`。**镜像 HIVEFS-4 `listFromFileSystem` 的既定规则**。 + +## Implementation Plan +1.

close、全 scheme 路由），HIVEFS-4/5 已把读扫描 + ACID 接上；写路径是最后一条未接的分支。本步把 `getFileSystem()` 的 FS **来源**从"本地 ServiceLoader 造对象存储 FS"换成"借引擎 `context.getFileSystem(session)`"——**下游 20 个调用点全不动**（它们已用 Doris `FileSystem` API），唯 MPU 两处需从 switching-facade 解出**具体** `ObjFileSystem`。 + +## Design + +### 1. 会话捕获（`beginWrite` 时） +`context.getFileSystem(session)` 需 `ConnectorSession`。`beginWrite(ConnectorSession session, …)`（:207）是唯一预提交入口、已捕获 user。新增字段 `private ConnectorSession session;`，`beginWrite` 首行 `this.session = session;`。`ConnectorSession` 已 import（:25）。 +- **session 可为 null 的两条路径**（均安全）：① 单测 `beginWrite(null, …)`；② rollback-before-commit（`rollback()`:292，`hmsCommitter==null`，仅 abort 悬挂 MPU）——生产中 `beginWrite` 恒先于 `addCommitData/commit/rollback`（`planWrite` 在 BE 执行前调），故此路径 session 实为已捕获；纯 rollback（无 beginWrite）仅测试构造。引擎 `DefaultConnectorContext.getFileSystem`（HIVEFS-3）**忽略 session**（catalog 级），null 安全；契约标注 identity 经 `session.getUser()` **预留** per-user。 + +### 2. `getFileSystem()` 换来源（:755-776） +删懒建 + `fs` 字段 + `resolveObjectStoreFileSystem` + OBJECT_STORAGE 过滤，改为借引擎 FS： +```java +private FileSystem getFileSystem() { + FileSystem engineFs = context.getFileSystem(session); + if

properties)"); + } + return engineFs; +} +``` +- 引擎已 per-catalog 懒建 + 缓存 `SpiSwitchingFileSystem`（HIVEFS-3），故连接器侧**无需**再本地缓存 `fs` 字段（删之，连带删 :119-121 注释）。 +- 空 storage → 引擎返 null → 本处 loud（HDFS/对象存储 hive 表都有 storage，仅无存储的畸形 catalog 命中，即时可诊断优于 NPE）。 + +### 3. MPU 两处解具体 `ObjFileSystem`（`forLocation`） +`getFileSystem()` 现返 `SpiSwitchingFileSystem`（facade，**非** `ObjFileSystem`）。非-MPU 的 19 个调用点用**基类** `FileSystem` 方法（`exists`/`delete`/`renameDirectory`/`listFiles*`…），switching FS 内部**逐操作** `forLocation` 路由到具体 FS（`SpiSwitchingFileSystem:116-160`）→ **不动**。唯 MPU 两处要 narrow 到 `ObjFileSystem`（`completeMultipartUpload`/`getObjStorage()` 不在基类接口上），须先 `forLocation` 解出具体 FS： + +- **`objCommit`（:803-833，complete，strict）**：把 :808 `FileSystem resolved = getFileSystem();` 换为 + ```java + FileSystem resolved; + try { + resolved = getFileSystem().forLocation(Location.of(path)); // path=写目标(native scheme) + } catch (Exception e) { // 宽 catch：forLocation 可抛 StoragePropertiesException(RuntimeException) + throw new DorisConnectorException("Failed to resolve object-store filesystem for MPU commit at " + + path + ": " + e.getMessage(), e); + } + if (!(resolved instanceof ObjFileSystem)) { throw …(:809-813 不变); } + ObjFileSystem objFs = (ObjFileSystem) resolved; // 循环体不变 + ``` + `path` 是该分区/表的写目标（**native HMS scheme**：S3 兼容=`s3://`、Azure=`abfss://`；MPU 只在 `hasPendingUploads` 且对象存储写时触发）；`type`-match 解析对所有后端（含 Azure）成立，与循环内 `remotePath="s3://bucket/key"`（传 complete API 的 BE 统一口径）同 catalog 凭证。fail-fast 语义（非对象存储即抛）保留；catch `Exception`（非 `IOException`）兜住 `forLocation` 的 `StoragePropertiesException`（RuntimeException）→ loud-wrap。 +- **`abortMultiUploads`（:1330-1356，abort，lenient）**：把 :1334 循环外 `getFileSystem()` 移入**循环内逐 upload** 解析 FS，**用 upload 的 native-scheme 路径 `u.path`**（=`pu.getLocation().getWritePath()`，:465——非合成 `s3://`；与 objCommit 用 `path` 对称）`forLocation(Location.of(u.path))`，`forLocation`/instanceof 失败 → `LOG.warn`+`continue`（对齐现有 :1336-1339 warn+skip 的 abort 宽松语义，不抛）： + ```java + for (UncompletedMpuPendingUpload u : uncompletedMpuPendingUploads) { + TS3MPUPendingUpload mpu = u.s3MPUPendingUpload; + String remotePath = "s3://" + mpu.getBucket() + "/" + mpu.getKey(); // BE-unified s3:// 路径（传 abort API） + FileSystem

`objFs.getObjStorage().abortMultipartUpload(remotePath, …)` 在 context.executeAuthenticated 内） + } + uncompletedMpuPendingUploads.clear(); + ``` + - **红队 major 折入**：① 解析源用 `u.path`（native scheme：Azure=`abfss://`、S3 兼容=`s3://`）而非合成 `"s3://"+bucket+"/"+key`——否则 Azure-typed catalog（`getStorageName()="AZURE"≠"s3"`）的 `s3://` 无法解析。② catch **`Exception`**（非 `IOException`）——`SpiSwitchingFileSystem.forLocation` props 解析失败抛 `StoragePropertiesException`（**RuntimeException**，非 IOException），窄 catch 无法兑现 abort 的 "resolve 失败→warn+skip" 宽松契约，会逃逸破坏 rollback、泄漏 server 端 MPU（vs HEAD 直建 Azure FS 成功 abort 的回归）。objCommit 同步 catch `Exception`→loud-wrap（strict）。`remotePath`（`s3://bucket/key`，BE 统一口径）仍传 `abortMultipartUpload` API 不变。 + +### 4. `close()` 不关借用

**删**：`java.util.ServiceLoader`（:73）、`org.apache.doris.filesystem.properties.StorageKind`（:40）、`org.apache.doris.filesystem.properties.StorageProperties`（:41）、`org.apache.doris.filesystem.spi.FileSystemProvider`（:42）——已核实仅

they are not bundled into the plugin lib/"`）。 +- `FileSystemPluginManager:72` parent-first 前缀含 `"org.apache.doris.filesystem."` → filesystem 插件对 `org.apache.doris.filesystem.spi.ObjFileSystem` **parent-first** 解析。 +- ⇒ 连接器与 s3 插件解析**同一** `ObjFileSystem` Class 对象 → `resolved instanceof ObjFileSystem` 真、`(ObjFileSystem) resolved` 不 ClassCast。生产 `SpiSwitchingFileSystem.forLocation("s3://…")` → 具体 `S3CompatibleFileSystem` 子类（is-a `ObjFileSystem`）。 + +**`forLocation` 默认语义**：`ObjFileSystem` **不** override `forLocation` → 用 `FileSystem` 接口默认 `return this`（HIVEFS-1 加）。故：① 生产具体 S3 FS `forLocation(x)`=自身（already 具体）；② 单测 fake `RecordingObjFileSystem`（extends `ObjFileSystem`）`forLocation(x)`=自身 → instanceof 过。switching FS 的 `forLocation` override 才做 per-scheme 路由（生产入口）。 + +**TCCL 无新增钉点**：MPU complete/abort 仍在 `context.executeAuthenticated(...)`（:822/1346）内 → `TcclPinningConnectorContext` 已钉插件 loader（memory `catalog-spi-plugin-tccl-classloader-gotcha` 既有 locus）；`forLocation` 建 S3 FS 走 AWS SDK（非 Hadoop `getHadoopFs` 的 "No FileSystem for scheme" 类），且 S3 provider 由引擎 `FileSystemFactory` 造，无连接器侧 TCCL 责任。 + +## Implementation Plan +1. `HiveConnectorTransaction.java`：字段（+`session`、−`fs`）、`beginWrite` 捕获 session、`getFileSystem()` 换来源、删 `resolveObjectStoreFileSystem`、MPU 两处 `forLocation`、`close()` 去 `fs.close()`、class-javadoc 订正、import 增删（§1-6）。 +2. `HiveConnectorTransactionTest.java`：注入缝从 `resolveObjectStoreFileSystem`-override 迁到 `FakeConnectorContext.getFileSystem(session)`-override（返回 fake `ObjFileSystem`）。 +3. build（`-pl :fe-connector-hive -am`）+ 靶向 UT（`-Dtest=HiveConnectorTransactionTest`）+ 0 checkstyle + import 门净。 + +## Risk Analysis +- **`instanceof ObjFileSystem` 跨边界**（最险）→ 已逐点取证成立（见上「关键正确性核验」），provided-scope + parent-first 双证。**e2e 兜底**：真集群对象存储 hive INSERT（MPU complete）+ rollback（MPU abort）。 +- **误 close 借用 FS**：§4 删 `fs.close()`；引擎所有、catalog 关。 +- **session=null**：引擎/fake 均忽略；契约标注 per-user 预留。 +- **`forLocation` × switching 缓存**：`SpiSwitchingFileSystem.forLocation`→`forPath`→按 `StorageProperties` 值相等缓存（`:66/94`）；同 catalog 对象存储凭证唯一 → MPU 各

FileSystem`（**不 extends `ObjFileSystem`**）：`forLocation(loc)` 返回被包裹的 `RecordingObjFileSystem`；base 方法（exists/mkdirs/delete/rename/list/newInputFile/newOutputFile）委派该 delegate；`close()` 抛 `AssertionError`（借用契约守卫）。 +- `newTxnWithFs` 用**匿名 `FakeConnectorContext` 子类**（override `getFileSystem(ConnectorSession)` 返回 `new RoutingFacadeFileSystem(RecordingObjFileSystem)`，忽略 session）。 +- **为何 facade 而非直接返回 `RecordingObjFileSystem`（红队 minor-2）**：直接返回则 fake **本身**是 `ObjFileSystem`，`instanceof` 恒过——测不出"漏调 `forLocation`"的回归（生产 facade 非 ObjFileSystem，漏调即 instanceof 失败/throw）。facade 强制走 `forLocation` narrow：漏调 → `getFileSystem() instanceof ObjFileSystem` 对 facade 为 false → 3 MPU 用例 RED。 +- **借用守卫（红队 minor-4，改必做非可选）**：facade `close()` 抛 `AssertionError`；现有 3 MPU 用例已 `txn.close()`——若 §4 漏删 `fs.close()`（或回归重加 close 借用 FS）→ RED。 +- **3 个 MPU 用例断言不变**：`testCommitCompletesMultipartUploads`（complete 一次、ETag 按 part 排序）、`testRollbackAbortsPendingMultipartUploads`（abort 一次，rollback-before-commit 走 session=null 路径 → **顺带证 null-session 安全**）、`testSecondRollbackIsIdempotent`（幂等 abort 一次）。 +- 其余 9 用例（分类/NEW→APPEND/事务表拒/`getUpdateCnt`/`profileLabel`/dup-partition/addPartitions-once）不碰 FS 或走 FILE_S3 write==target 无 rename → 不受影响；`beginWrite(null,…)` 现已传 null，迁移后仍 null（引擎/fake 忽略）。 +- **import bookkeeping（红队 minor-1，必做否则编译/checkstyle 挂）**：`HiveConnectorTransactionTest` 加 `import org.apache.doris.connector.api.ConnectorSession;` + `import java.io.IOException;`（facade 委派方法声明）；删 `import

Both existing + ctors keep working unchanged. +- Add the field to `equals`/`hashCode`/`toString` (value-based contract; `ConnectorPartitionInfoTest` enforces it). + +**(b) fe-core — `PluginDrivenMvccExternalTable.java`** — thread the flag through `toListPartitionItem`; the +lone caller is `listLatestPartitions` L276: +```java +// L276: +nameToPartitionItem.put(partitionName, toListPartitionItem(partitionName, types, part.getPartitionValueNullFlags())); + +// builder: +private static ListPartitionItem toListPartitionItem(String partitionName, List types, + List nullFlags) throws AnalysisException { + List partitionValues = HiveUtil.toPartitionValues(partitionName); + Preconditions.checkState(partitionValues.size() == types.size(), partitionName + " vs. " + types); + // Fail loud (RT-F1): a connector that supplies flags MUST supply one per value; a short list would + // silently default the tail to isNull=false and re-introduce the drop bug.

Under B it + must describe the connector-supplied flag: a genuine-NULL value (hive's HMS sentinel, paimon's + `partition.default-name`) is marked `isNull=true` by its connector → typed `NullLiteral` → `col IS NULL` + selects it and MTMV refresh materializes the null rows; a connector that supplies no flag defaults to non-null. + +**(c) hive connector — `HiveConnectorMetadata.java` (`listPartitions` ~L1105)** — build the positional flag +list by **iterating `HiveWriteUtils.toPartitionValues(partitionName)` directly** (RT-F5: the same positional +parse fe-core re-runs, so flag[i] zips to value[i] regardless of column casing/order — do NOT iterate the +value Map/partKeyNames). Detection uses an **exact** `ConnectorPartitionValues.HIVE_DEFAULT_PARTITION.equals(value)` +compare, **not** `isNullPartitionValue` (RT-F2: byte-parity with legacy `HiveExternalMetaCache:309`, which +marks null on the sentinel only — `isNullPartitionValue` also widens to `\N`/Java-null, an unwanted parity +divergence; HMS partition names never carry `\N` anyway). Pass the 8-arg ctor. The sentinel constant already +lives connector-side (`ConnectorPartitionValues.HIVE_DEFAULT_PARTITION`, already a hive dependency). + +**(d) paimon connector — `PaimonConnectorMetadata.java` (`collectPartitions` ~L1044-1080)** — build a +positional flag list in the **same `spec.entrySet()` loop** that builds the name; set `true` at the existing +null branch L1050 (`defaultPartitionName.equals(value)`) — paimon detects its own default-name, NOT the hive +sentinel. Pass the flag list to the ctor. **Keep the name normalization to `__HIVE_DEFAULT_PARTITION__` +(L1057) unchanged** — the partition NAME identity must not change (avoids re-keying existing partitions / +MTMV names). Update the L1050-1057 comment: the intent it describes ("bridge marks the partition isNull") is +now *realized* via the supplied flag. + +**(e) fe-core — `PluginDrivenScanNode.java` opt-out comment (L238-280)** — comment-only. The +`ignorePartitionPruneShortCircuit` opt-out **code + capability stay** (still required for genuine predicate +prune-to-zero, e.g. paimon `col = `). But its worked example — "with `isNull=false` a +genuine-null partition renders as a non-null sentinel, so `col IS NULL` prunes every partition away" (L244-246, +L272-275) — is **stale under B**: paimon's null partition is now a real `NullLiteral`, so `col IS NULL` +prunes *accurately* to it (non-empty selection → opt-out at L276 does not fire; planScan still re-plans). +Replace the `col IS NULL` example with a still-valid one (`col = ` → genuine prune-to-zero). + +**(f) other connectors** — hudi (`HudiConnectorMetadata.java:709`), maxcompute +(`MaxComputeConnectorMetadata.java:274`), iceberg (`IcebergPartitionUtils.java:545`): keep their existing +ctors → flags default empty → `isNull=false`. **Zero change.** + +### 3.3 Out of scope (noted follow-ups) + +- **iceberg latent analogous bug**: identity/bucket/truncate LIST branch renders a genuine Java-null as the + literal text `col=null` (`IcebergPartitionUtils.java:620`); on a non-string column fe-core throws and drops + the partition — the same failure mode. The flag mechanism would let iceberg opt in at + `IcebergPartitionUtils.java:542-543` (typed Java-null already in hand), but iceberg is not in any failing + suite and this touches signed-off P6 code. **Deferred** to a separate task (user-agreed). + +## 4. Iron-Rule Compliance + +fe-core has **no** source-specific code after the fix: `toListPartitionItem` reads a connector-supplied +`List` and calls `new PartitionValue(value, isNull)`. No `if (hive/paimon)`, no `instanceof HMS*`, +no `HIVE_DEFAULT_PARTITION.equals(...)` in fe-core. The sentinel/default-name compare lives entirely in each +connector. The new field is a generic per-value nullness carrier, semantically identical to the existing +`ConnectorPartitionValues.Normalized.isNull` list already in the API module. (Pre-existing fe-core sentinel +compares at `TablePartitionValues.java:162` and the non-MVCC base path are **not reached by hive/paimon** — +overridden by the MVCC subclass — and are left untouched.) + +## 5.

Risk Analysis / Blast Radius + +- **paimon behavior change** (the wider-scope part of B): its genuine-null partition flips from + `StringLiteral` to `NullLiteral`. Downstream touch points to verify in red-team: (1) MTMV refresh + (`UpdateMvByPartitionCommand.java:183-202` — NullLiteral → `col IS NULL`, StringLiteral → `col IN`); + (2) the `PluginDrivenScanNode` prune opt-out (still needed for `col=`, no longer needed for + `col IS NULL`); (3) partition NAME identity unchanged (name normalization kept); (4) partition count + display now counts the paimon null partition (was: string partition, also counted — no `0/0` regression + since paimon string sentinel never threw). +- **`ConnectorPartitionInfo.equals/hashCode/toString`**: field added to all three; existing equal instances + stay equal (both empty lists). +- **ctor compatibility**: both existing ctors preserved; only hive + paimon use the new 8-arg ctor. All other + construction sites and tests compile unchanged. +- **Non-MVCC base path / SHOW PARTITIONS**: untouched — consume the value map or name only, never + `toListPartitionItem`. +- **`partition_values()` TVF / `$partitions`** (RT-F6): the flag is **not** threaded here (separate surface — + `getNameToPartitionValues` → `MetadataGenerator.partitionValuesRows`, string-compares the raw value against + the hive sentinel at `:2166`). **hive** is unaffected (its value map carries `__HIVE_DEFAULT_PARTITION__`, + matched at `:2166`). **paimon** is a **pre-existing** gap (NOT introduced or worsened by this fix): its value + map carries the RAW `partition.default-name` (e.g. `__DEFAULT_PARTITION__`), which `:2166` does not match, so + a non-string paimon default-partition column throws `Integer.valueOf("__DEFAULT_PARTITION__")` at `:2177`. The + §5 correction: this fix restores the LIST/scan/prune surface only; the paimon TVF surface is **out of scope** + (deferred follow-up, same iron-rule reason — fe-core can't string-detect paimon's default-name). +- **Impacted EXISTING e2e suite — `mtmv_p0/test_paimon_mtmv.groovy`** (RT-F3, MAJOR): it builds an MTMV over the + paimon `null_partition` table (`partition by(region)`) with a `// Will lose null data` comment and a committed + golden (`test_paimon_mtmv.out:138-141`) that deliberately **omits** the two genuine-NULL `region` rows. Under + B the null partition becomes a `NullLiteral` → MTMV refresh emits `region IS NULL` → the MV **gains** those + rows → golden flips 3→5 rows. This is an **expected** behavior change, not a new test: (1) update the stale + `// Will lose null data` comment; (2) the `.out` golden must be **regenerated by the e2e run** (do NOT + hand-write — `勿 rebless data-wrong`); (3) **e2e gate**: confirm the MV auto-creates the null list partition + (`VALUES IN (NULL)`) without throwing — the `region` column is nullable (base STRING, no NOT NULL) so it + should be allowed, but a NOT-NULL partition column would be rejected (`test_null_partition.groovy:44`); if it + throws, B breaks paimon MTMV creation and must be gated. + +## 7.

Benign: equality-compare in `tablesOrDataChanged` is the real + correctness mechanism; the interval gate is only a perf heuristic ("don't cache a table that changed in + the last N seconds"). Hive keeps exact legacy semantics because its token *is* epoch-ms. +- **meta-cache staleness bound:** the freshness token reflects the `CachingHmsClient` meta cache + (TTL-bounded), not the live metastore. This is **the same bound legacy operated under** (legacy read + `transient_lastDdlTime` from the schema-cache-loaded table) and the same bound the scan itself uses, so + the cache is never *more* stale than a fresh (uncached) query would be. Acceptable, unchanged contract. +- **time-travel (`FOR VERSION/TIME AS OF`):** cache key = SQL text (includes the snapshot clause) → keys + never collide; token = *latest* version, so a pinned-snapshot result may be *over*-invalidated when new + data lands (harmless perf loss, never wrong data — the pinned snapshot is immutable).

Both HMS calls are **meta-cache-backed** +(`CachingHmsClient`), so a warm cache makes them in-memory reads; the residual cost is CPU (building the +partition items + the max scan). Unpartitioned hive is cheap (freshness from the handle, no round-trip); +snapshot-id connectors (iceberg/paimon) read a monotonic version. The token is also computed **twice** per +query (store: L2 `addUsedTable` + L4 `buildCacheTableForExternalScanNode`). + +**Why this is acceptable to ship, not a blocker:** (a) opt-in, `enable_hive_sql_cache` default **false** — zero +production cost by default; (b) a cache HIT pays ≈ the *metadata* portion of planning (which a cache MISS pays +anyway) and **skips the entire BE data scan** — so a hit is always cheaper than a miss, the feature is always +net-positive; (c) the meta-cache amortises repeated lookups; (d) it matches the already-accepted cost of the +MV/dictionary poll that calls the same method. + +**Registered follow-up optimisation (separate task, NOT this change):** short-circuit +`getNewestUpdateVersionOrTime()` to skip `materializeLatest()` on the last-modified branch (read the freshness +kind from `beginQuerySnapshot` alone, then `queryTableFreshness()`), collapsing the double handle-resolution +and dropping the discarded partition-item enumeration.

Verified: the plugin's `setScanParams` override never +re-touches `compress_type`, so the value set here survives to BE (red-team confirmed). + +**C. Hive override** — `HiveScanPlanProvider`: +```java +@Override +public TFileCompressType adjustFileCompressType(TFileCompressType inferred) { + return inferred == TFileCompressType.LZ4FRAME ? TFileCompressType.LZ4BLOCK : inferred; +} +``` +Exact legacy parity; the hadoop-specific fact stays inside the connector.

Hudi strict-parity (red-team call) + +Legacy `HudiScanNode extends HiveScanNode` (`HudiScanNode.java:94`) and **inherited** the remap.

Left un-migrated it throws `ClassCastException` post-flip: `MaxComputeExternalDatabase.buildTableInternal:44` casts `extCatalog` to `MaxComputeExternalCatalog`, but a replayed catalog is now `PluginDrivenExternalCatalog`. es/jdbc/trino migrated catalog+**db**+table together (their legacy DB classes are deleted). T05 therefore migrated **all three** GSON registrations to `registerCompatibleSubtype` + removed the 3 now-unused `maxcompute.*` imports. Verified safe: `InitDatabaseLog.Type.MAX_COMPUTE` has no replay-dispatch use (self-ref only); `dbLogType` is not `@SerializedName` → handled identically to the shipped es/jdbc/trino DBs. +- **Adversarial verification fan-out (4 read-only agents) — 2 alarms adjudicated as non-issues:** + - *`getMetaCacheEngine()` → "default" not "maxcompute"* = **false positive.** The plugin path loads schema via the connector (`PluginDrivenExternalTable.initSchema`) under the "default" bucket — exactly as shipped es/jdbc/trino tables (which never overrode it). `MaxComputeExternalMetaCache` is referenced only by legacy `MaxComputeExternalTable:71,122` (Batch-D dead code); partitions come from the connector (P4-T02). No override needed. + - *`getMysqlType()` → "BASE TABLE" not null* = **consistent with accepted precedent.** Migrated ES tables already went null→"BASE TABLE" (`ES_EXTERNAL_TABLE` is absent from `TableType.toMysqlType`) and shipped with no override. MC matching is the same accepted change. + - *dormancy ("a new MC catalog can't serialize in the T05↔flip window")* = the **already-documented** intermediate-state caveat above. The agent's suggested fix (keep `registerSubtype` too) is **wrong** — coexistence throws the duplicate-label IAE the atomic replace exists to avoid. No action. +- **Test:** `PluginDrivenExternalTableEngineTest` extended with 2 `max_compute` cases (engine = null; type name = `MAX_COMPUTE_EXTERNAL_TABLE`) — 9/9 green.

Mapping must be a direct literal `"max_compute" → ENGINE_MAXCOMPUTE`. +- Downstream is satisfied once padded: `checkEngineName` (`:940-944`) and `analyzeEngine` + (`:1121-1127`) whitelist `ENGINE_MAXCOMPUTE`, so producing `"maxcompute"` makes the rest of the + path byte-identical to legacy with zero further edits. + +## Design +Mirror the in-repo convention `PluginDrivenExternalTable.getEngine()` (switch on +`((PluginDrivenExternalCatalog) catalog).getType()`): add a `PluginDrivenExternalCatalog` branch to +both gate methods, keyed on `getType()` (not a hardcoded `instanceof MaxComputeExternalCatalog`), so +it generalizes to any future full-adopter and survives Batch-D deleting the legacy MC branch. + +1. **Import** — add `import org.apache.doris.datasource.PluginDrivenExternalCatalog;`. **Placement + (critic correction):** immediately after `:49 org.apache.doris.datasource.InternalCatalog` and + **before** `:50 org.apache.doris.datasource.hive.HMSExternalCatalog`. Rationale: Checkstyle + `CustomImportOrder` is ASCII-case-sensitive; after `org.apache.doris.datasource.` the next char is + uppercase `P` (0x50) for PluginDriven vs lowercase `h`/`i`/`m`/`p` (≥0x68) for the + `hive.`/`iceberg.`/`maxcompute.`/`paimon.` sub-packages, so `P` sorts **before** all of them and + **after** `I` (InternalCatalog, 0x49). Grouped with the top-level `datasource.*` classes + (`CatalogIf :48`, `InternalCatalog :49`), NOT after the sub-packages. (The parent design's + "between :51/:52, after MaxCompute" was off-by-two and would put it after `hive`/`iceberg` → + Checkstyle reject.) + +2. **`paddingEngineName`** — insert after the MC branch (`:913`), before the `:914 else`: + ```java + } else if (catalog instanceof PluginDrivenExternalCatalog + && pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog) != null) { + engineName = pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog); + } else { + throw new AnalysisException("Current catalog does not support create table: " + ctlName); + } + ``` + A max_compute PluginDriven catalog gets `engineName = "maxcompute"`. A jdbc/es/trino PluginDriven + catalog (helper returns `null`) falls through to the existing `else` and throws the **same** + "does not support create table" message it already throws today — byte-identical pre/post for + those types. + +3. **`pluginCatalogTypeToEngine` (new `private static`) — RETURNS `null` for unmapped types, does + NOT throw** (refinement over parent design — Rule 7): + ```java + // Maps a PluginDriven (SPI) catalog's type to the legacy engine name used for DDL + // engine-padding / catalog-engine consistency. Keyed on getType() (CatalogFactory key), + // mirroring PluginDrivenExternalTable.getEngine()/getEngineTableTypeName(); the two switches + // must stay in sync if SPI_READY_TYPES gains a CREATE-TABLE-capable full-adopter. + // Returns null for SPI types that do not support CREATE TABLE (jdbc/es/trino-connector), + // so callers preserve their existing behavior for those types. + private static String pluginCatalogTypeToEngine(PluginDrivenExternalCatalog catalog) { + switch (catalog.getType()) { + case "max_compute": + return ENGINE_MAXCOMPUTE; + default: + return null; + } + } + ``` + **Why null, not default-throw (the parent design's version):** the helper is shared by BOTH gate + methods. If it threw for non-max_compute types, then `checkEngineWithCatalog` — which legacy lets + jdbc/es/trino pass through unconditionally (they are not in legacy's instanceof chain) — would + newly throw for a jdbc catalog with an explicit engine. Returning null lets each caller keep + legacy semantics: `paddingEngineName` falls to its existing else-throw; `checkEngineWithCatalog` + simply skips. This makes jdbc/es/trino byte-identical to legacy in **both** methods; only + max_compute gains behavior. + +4. **`checkEngineWithCatalog`** — insert after the MC branch (`:391`), before the `:392` close: + ```java + } else if (catalog instanceof PluginDrivenExternalCatalog) { + String pluginEngine = pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog); + if (pluginEngine != null && !engineName.equals(pluginEngine)) { + throw new AnalysisException("MaxCompute type catalog can only use `maxcompute` engine."); + } + } + ``` + `pluginEngine` is non-null only for max_compute, so the message is only ever reachable for + max_compute and is the **verbatim legacy MC message** (`:391`) — matching the established + convention asserted for sibling catalogs (`test_iceberg_create_table.groovy` / `test_hive_ddl.groovy`: + `" type catalog can only use \`\` engine."`). jdbc/es/trino (pluginEngine == null) + fall through with no throw, exactly as legacy. + +5. **SPI / connector / thrift / BE: no change.** The `Connector` SPI has no engine-name concept; + adding one is over-design. `getType()` is sufficient. Pure fe-core. + +## Implementation Plan (fe-core only) +1. `CreateTableInfo.java`: add the import (§Design 1, exact placement). +2. `CreateTableInfo.java:896-918 paddingEngineName`: insert the PluginDriven branch (§Design 2). +3. `CreateTableInfo.java:376-393 checkEngineWithCatalog`: insert the PluginDriven branch (§Design 4). +4. `CreateTableInfo.java`: add `private static pluginCatalogTypeToEngine` (§Design 3). +5.

Independent commit `[P4-T06d] FIX-DDL-ENGINE`. + +## Risk +- **Regression surface is narrow**: a new branch fires only when (padding) `engineName` is empty AND + catalog is PluginDriven, or (check) catalog is PluginDriven. HMS/Iceberg/Paimon/Internal and + legacy-MC (`instanceof MaxComputeExternalCatalog`, still in keep-set) paths are byte-unchanged + (branch order: after MC, before else / before close). +- **jdbc/es/trino**: byte-identical to legacy in both methods (null-returning helper, §Design 3). + No new capability, no new breakage.

The helper comment cross-references both so a + future SPI_READY_TYPES key change updates both switches. +- **Checkstyle/import-gate**: one new import, used in 3 places; placement verified (§Design 1). + +## Batch-D ordering (keep-set dependency — must record in decisions-log) +`P4-batchD-maxcompute-removal-design.md:100` plans to delete both +`instanceof MaxComputeExternalCatalog` branches in `CreateTableInfo`. This fix **must land first**; +Batch-D then degrades to "delete only the legacy MC instanceof branches + the +`maxcompute.MaxComputeExternalCatalog` import", leaving the PluginDriven branches (keyed on +getType()) in place. If Batch-D runs first, no-ENGINE CREATE TABLE is permanently broken (the +"amendment self-triggers" pattern). This fix depends on the `MaxComputeExternalCatalog` import +staying in keep-set until Batch-D. (Confirmed `UnboundTableSinkCreator` already has PluginDriven +branches from T06c, so `CreateTableInfo` is the last unwired analysis-time CREATE TABLE gate.) + +## Test Plan +**UT (CI-runnable, fe-core)** — new file +`fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/info/CreateTableInfoEngineCatalogTest.java` +(same package → can construct `CreateTableInfo`; private gate methods invoked via reflection). +Infra (mirrors `PluginDrivenExternalCatalogDdlRoutingTest`): `MockedStatic` → +`mockEnv.getCatalogMgr()` → `mockCatalogMgr.getCatalog("mc_ctl")` returns a +`Mockito.mock(PluginDrivenExternalCatalog.class)` with `getType()` stubbed to `"max_compute"` (a +Mockito mock IS an `instanceof PluginDrivenExternalCatalog`; getType() is non-final). **This +registration via the mocked CatalogMgr is mandatory** because both gate methods look the catalog up +by name (critic correction — a directly-constructed catalog would be ignored). + +Cases (each assertion message encodes WHY — Rule 9; each fails if its branch is reverted): +1. `noEnginePaddedToMaxcomputeForPluginDriven` — `CreateTableInfo` with empty engine, ctl `"mc_ctl"`; + reflectively invoke `paddingEngineName("mc_ctl", null)`; assert `getEngineName() == "maxcompute"`. + WHY: no-ENGINE CREATE TABLE must auto-pad maxcompute, not throw. (Revert branch → throws "does not + support create table" → red.) +2. `ctasNoEnginePaddedToMaxcompute` — drive the **CTAS** entry point + `validateCreateTableAsSelect(["mc_ctl"], , ctx)` far enough to assert padding ran (assert + `getEngineName() == "maxcompute"` after the call, or that it does not throw "does not support + create table"). Covers the CTAS path the parent design omitted. (If `validate(ctx)` downstream is + too heavy to run headless, assert via `paddingEngineName` re-invocation parity + a focused + `assertDoesNotThrow` up to the padding point; final form decided at implementation against what + runs offline.) +3. `wrongExplicitEngineRejectedForPluginDriven` (Rule-9 mirror test) — set `engineName="hive"`, + ctl `"mc_ctl"`; reflectively invoke `checkEngineWithCatalog()`; assert `AnalysisException` + thrown. WHY: catalog-engine consistency must still hold under PluginDriven. **This fails (no + throw) if the checkEngineWithCatalog branch is absent** — proving the mirror branch against its + intent (the parent design had no such test; the branch would otherwise be untestable per Rule 9). +4. `correctExplicitEnginePassesForPluginDriven` — `engineName="maxcompute"`, + `checkEngineWithCatalog()` does not throw (locks that the check is a consistency gate, not a + blanket reject). +5. `jdbcPluginDrivenStillUnsupported` — getType() stubbed `"jdbc"`; `paddingEngineName` (empty + engine) throws "does not support create table" (helper returns null → existing else); and + `checkEngineWithCatalog` with any explicit engine does NOT throw (mirrors legacy pass-through). + Locks the null-returning-helper decision (§Design 3) against regression. + +Reflection helper unwraps `InvocationTargetException` to rethrow the cause so `assertThrows` +sees `AnalysisException` directly. + +**E2E (NOT run in normal CI — needs live ODPS):** +`regression-test/suites/external_table_p2/maxcompute/test_max_compute_create_table.groovy` Test1 +(`:62-71`, no-ENGINE Basic CREATE TABLE) is the natural assertion point: under cutover it must go +from FAIL → PASS (CREATE TABLE succeeds, `show tables like` hits, `qt_test1_show_create_table` +renders without error). **Do NOT add the parent design's proposed extra assertion +"SHOW CREATE TABLE output contains `ENGINE=maxcompute`"** (critic correction): SHOW CREATE TABLE +renders `ENGINE=` + `getEngineTableTypeName()` = `"MAX_COMPUTE_EXTERNAL_TABLE"` (the recorded `.out` +baseline line 3 confirms `ENGINE=MAX_COMPUTE_EXTERNAL_TABLE`), NOT `maxcompute`.

Legacy worked; cutover breaks it. Severity: **blocker**. + +## Root Cause + +Direct cause: `MaxComputeConnectorMetadata` lacks a `buildTableDescriptor` override (unlike +`JdbcConnectorMetadata.java:182-217` / `EsConnectorMetadata.java:121-131`). The dispatch + +SPI hook + null fallback in fe-core are correct and generic; the fix belongs in the MC connector. + +## Design (decisions B1–B4) + +- **B1** — Add `@Override public org.apache.doris.thrift.TTableDescriptor buildTableDescriptor(...)` + to `MaxComputeConnectorMetadata` with the SAME signature as the SPI default. Build a `TMCTable` + and call `setEndpoint(endpoint)`, `setQuota(quota)`, `setProject(dbName)`, `setTable(remoteName)`, + `setProperties(properties)`. `project`/`table` use the **remote-name params** (`dbName`, + `remoteName` are already remote at the call site — see B-registrations OQ-7). Do **not** set + region/access_key/secret_key/public_access/odps_url/tunnel_url (legacy leaves them unset / + deprecated — mirror that; credentials flow through the `properties` map). +- **B2** — Construct + `new org.apache.doris.thrift.TTableDescriptor(tableId, TTableType.MAX_COMPUTE_TABLE, numCols, 0, tableName, dbName)` + then `setMcTable(tMcTable)`. The **6th ctor arg (descriptor dbName field) = remote `dbName` param**, + mirroring legacy `MaxComputeExternalTable.toThrift:318-319` which passes `dbName` there. BE does + NOT read this field for MC reads (JNI scanner uses `TMCTable.project/table`), so it is harmless, + but we mirror legacy faithfully (this diverges from jdbc/es which pass `""` — recorded below). +- **B3** — Extend `MaxComputeConnectorMetadata` ctor with + `private final String endpoint; private final String quota; private final Map properties;` + (reuse existing `java.util.Map` import) + corresponding ctor params; assign them. Update + `MaxComputeDorisConnector.getMetadata` to pass `endpoint, quota, properties`. These fields are + assigned in `doInit()` and `getMetadata()` calls `ensureInitialized()` first, so they are non-null + at construction time. +- **B4** — Style: match the jdbc/es override exactly — fully-qualified `org.apache.doris.thrift.*` + names, **no new thrift imports**. The connector import-gate only forbids fe-core internal packages + and only scans `^import` lines in `src/main/java`; fully-qualified usage trips neither it nor + Checkstyle. The only reused import is `java.util.Map` (already present). + +## Implementation Plan (per file) + +1. `fe/fe-connector/fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java` + - Add three final fields `endpoint`, `quota`, `properties` and extend the ctor with the three + params; assign them. + - Add `@Override buildTableDescriptor(...)` per B1/B2 (fully-qualified thrift names). +2. `fe/fe-connector/fe-connector-maxcompute/.../MaxComputeDorisConnector.java` + - `getMetadata`: `new MaxComputeConnectorMetadata(odps, structureHelper, defaultProject, endpoint, quota, properties)`. +3. No changes to BE, thrift, fe-core, or any other connector. + +Gate: only the connector is touched → `mvn ... -pl :fe-connector-maxcompute` (no `-pl :fe-core`). + +## Risk + +- Low: pure new override + ctor passthrough. No fe-core dispatch / BE / thrift / other-connector + change. jdbc/es/trino unaffected (own override or null fallback). +- Keep-set untouched: legacy `MaxComputeExternalTable.toThrift` stays (unused under cutover; removed + in Batch D). No ordering conflict with this fix. +- BE `descriptors.cpp:289-320` reads region/access_key/... without `__isset` guards, but since we set + the whole `mcTable`, unset fields default to empty strings (not UB) — identical to legacy, which also + does not set them. + +## Test Plan + +- **UT** — new `MaxComputeBuildTableDescriptorTest` in + `fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/`. + Plain JUnit 5 (no fe-core dep, no Mockito). Construct `MaxComputeConnectorMetadata` directly with + `null` odps/structureHelper (ctor only assigns; `buildTableDescriptor` never dereferences them) and + real endpoint/quota/properties/defaultProject. Call `buildTableDescriptor(null, tableId, tableName, + dbName, remoteName, numCols, catalogId)` and assert: (1) result != null; (2) + `getTableType()==MAX_COMPUTE_TABLE`; (3) `isSetMcTable()`; (4) `mcTable.getEndpoint()/getQuota()/ + getProject()==dbName/getTable()==remoteName/getProperties()` equal inputs. Comment encodes WHY: BE + static_casts to `MaxComputeTableDescriptor` and reads these as the auth/addressing contract — a + SCHEMA_TABLE/null fallback crashes BE (Rule 9). The test FAILS if the override returns null or a + SCHEMA_TABLE descriptor. +- **E2E (user-run, live ODPS)** — under cutover, run `test_external_catalog_maxcompute.groovy` / + `test_max_compute_all_type.groovy` `SELECT` with column projection (a real-data SELECT, not just + `count(*)`, per critic gap) against existing `.out` baselines. +- **Build note (both modules).** Run these UTs with `-am` (e.g. + `mvn -f fe/pom.xml -pl :fe-core -am -DfailIfNoTests=false -Dtest=PluginDrivenExternalTableEngineTest test`). + Without `-am`, sibling SNAPSHOT artifacts (incl. the connector-api jar) resolve from a stale + `~/.m2`, causing `NoClassDefFoundError: ConnectorTransaction`. The `-am` reactor build also requires + `-DfailIfNoTests=false` so the `-Dtest=` filter does not fail upstream modules with "No tests were + executed". + +## Parity & boundary registrations + +- **OQ-7 — project/table use remote names (intentional fix).** The SPI read session itself uses + remote names: `PluginDrivenScanNode` builds the table handle from `db.getRemoteName()/table + .getRemoteName()`, and the JNI scanner does `requireNonNull(project)` + `odps.setDefaultProject( + project)`. So the descriptor MUST carry remote names to stay consistent with the read session; + reverting to legacy local names would diverge from the SPI read session. This is the correct, + not merely tolerable, choice (same family as DDL-P3/DDL-C2 remote-name fixes). Note: for the + actual data read the descriptor `project/table` are largely vestigial — real addressing uses the + FE-prebuilt serialized scan session — but they must still be the remote names for consistency and + to satisfy the BE `MaxComputeTableDescriptor` contract. +- **6th ctor arg dbName choice.** We pass the **remote `dbName` param** (mirrors legacy + `MaxComputeExternalTable.toThrift:318-319`), NOT `""` as jdbc/es do. BE does not read + `TTableDescriptor.dbName` for MC reads, so it is harmless; we choose legacy-faithful over + jdbc/es-uniform here, and record the deliberate divergence from the jdbc/es style. +- **UT coverage boundary (now closed — two-sided).** Coverage is split across two modules: + 1. The connector UT (`MaxComputeBuildTableDescriptorTest`) asserts the override's OWN output. It + CANNOT reach the fe-core `PluginDrivenExternalTable.toThrift` call site (cross-module; this + module has no fe-core dependency). + 2. The fe-core call site is now covered by + `PluginDrivenExternalTableEngineTest#testToThriftPassesRemoteNamesAndNumColsToBuildTableDescriptor` + (`fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalTableEngineTest.java`). + It uses a Mockito-mocked `ConnectorMetadata` with an `ArgumentCaptor` on `buildTableDescriptor`, + drives `table.toThrift()` (stubbing only the two Env-backed methods it traverses — + `makeSureInitialized()` and `getFullSchema()` — plus a `TestablePluginCatalog.getConnector()` + override that bypasses Env-backed catalog init), and asserts the captured args: + `dbName == "REMOTE_DB"` (≠ local `mydb`), `remoteName == "REMOTE_TBL"` (≠ local `mytbl`), and + `numCols == schema.size()`. Local names differ from remote names so a regression that passes + local names (or a wrong numCols) FAILS the test (verified by a temporary mutation: + `db.getRemoteName()→db.getFullName()` / `getRemoteName()→getName()` / `size()→size()+1` + produced `expected: but was: `).

DONE. +- `MaxComputeScanRange.java`: **unchanged** — `setSize(getLength())` and `Builder.length` default + (already `-1`) need no edit; the fix flows through naturally. + +## Risk — corrected impact analysis (3 consumers, not 2) +The parent `P4-cutover-fix-design.md` claimed (and grep "fully confirmed") that `getLength()` for a +byte_size range flows ONLY to `setPath` (`MaxComputeScanRange.java:120`) and `setSize` (`:122`). +**That is wrong.** `getLength()` has a THIRD consumer: + +1. `MaxComputeScanRange.populateRangeParams` `setPath` (cosmetic path string `:120`). +2. `MaxComputeScanRange.populateRangeParams` `setSize` (`:122`) — the BE sentinel; the load-bearing + one. +3. `PluginDrivenSplit.java:42` passes `scanRange.getLength()` into `FileSplit.length`, read + downstream by: + - `FederationBackendPolicy.java:499` — `primitiveSink.putLong(split.getLength())` in + consistent-hash backend assignment. + - `FileQueryScanNode.java:430` — `totalFileSize += split.getLength()`. + +After the fix, consumers (1)-(3) see `-1` instead of `268435456`. **This is BENIGN and improves +legacy parity** (legacy `MaxComputeSplit` also used `length=-1`; the buggy cutover diverged from +legacy here too). Concretely: +- (a) **Consistent-hash split→BE placement** will differ from the **current buggy build** (because + the hashed `getLength()` changes from 268435456 to -1). This is invisible/benign for correctness + and matches legacy. Do NOT mistake this A/B placement difference for a regression during + validation. +- (b) **`totalFileSize` goes negative** for byte_size scans (one `-1` per split). This is + pre-existing legacy behavior, used only for stats/cost/explain/logging, not correctness. It + propagates to profile/explain numbers and any cost heuristic keyed on `totalFileSize`. Low risk, + pre-existing. + +Other guarantees (verified): +- Cross-connector impact: **zero**. The sentinel is private to MaxCompute ↔ `MaxComputeJniScanner`; + the change is strictly inside the connector's byte_size branch. jdbc/es/trino/hive/hudi each carry + real file byte sizes, unrelated to this sentinel. (Note: any future generic use of + `ConnectorScanRange.getLength()==-1` by other code paths would need re-examination.) +- No edit-log/replay/HA concern: the change is purely query-plan-time scan-range construction, not + persisted. +- checkstyle / import gate: only a literal-arg change; `-1L` matches existing long-literal style; no + new imports/types. (Verified: 0 violations, import gate clean.) + +## Test Plan +**UT — CI-runnable guard (the only one that runs in normal CI):** +`fe-connector-maxcompute/.../MaxComputeScanRangeTest.java` (JUnit 5; module has no fe-core / no +Mockito). It drives the **provider's real byte_size split-building path** (`buildSplitsFromSession`, +invoked via reflection) with offline Serializable fakes for `TableBatchReadSession` / +`InputSplitAssigner` (returning a real `IndexedInputSplit`), then asserts the produced range's +`rangeDesc.getSize() == -1`. Two tests: +- `byteSizeBranchEmitsMinusOneSizeSentinel` — asserts size == -1 (plus startOffset == splitIndex and + path == `"[ 7 , -1 ]"`). **This guards the provider's CHOICE, not just the range mechanism**: + reverting the byte_size branch to `.length(splitByteSize)` makes it FAIL with + `expected: <-1> but was: <268435456>` (verified by a real revert — see below). +- `rowOffsetBranchKeepsRealRowCount` — contrast: the row_offset branch carries the real row count + (never the -1 sentinel), locking the intent that ONLY byte_size uses -1 (guards against an + over-broad "set everything to -1" fix). + +Each assertion message encodes WHY (Rule 9): BE distinguishes BYTE_SIZE vs ROW_OFFSET solely by +`size == -1`; a wrong value → silent corrupt read. + +**Why provider-level (not the weak range-level UT):** the parent design proposed a UT that builds a +range with `.length(-1)` itself then asserts `getSize()==-1`. That is weak — it sets length=-1 +itself, so it would NOT fail if the provider reverted to `.length(splitByteSize)`; it locks the +range mechanism, not the fix. This UT instead exercises the changed provider line, so it is a real +regression red point. + +**E2E (NOT run in normal CI):** `regression-test/suites/external_table_p2/maxcompute/ +test_external_catalog_maxcompute.groovy` is an `external_table_p2` suite requiring **live +MaxCompute/ODPS credentials**, so it is **SKIPPED in normal CI**. It is therefore NOT an unattended +guard for this fix — the UT above is the only CI-runnable automated guard. Under default byte_size +strategy, the suite's read assertions (count(*), select *, int_types, mc_parts) read corrupt data +before the fix and should match the legacy `.out` baseline after, but this requires a manual / +credentialed run. + +## Boundary notes +- **FIX-READ-SPLIT alone does NOT yield correct reads unless FIX-READ-DESC is also present** + (already done/committed). They are independent blockers on the same read path: FIX-READ-DESC fixes + the table descriptor (endpoint/quota/project/table/properties for BE auth+addressing); + FIX-READ-SPLIT fixes the per-split sentinel. The JNI scanner also requires `time_zone` + (`MaxComputeJniScanner.java:139` `requireNonNull`), injected by the BE JNI framework + (`jni_reader.cpp` `_scanner_params.emplace("time_zone", ...)`) for all JNI scanners — not by the + descriptor; this fix neither helps nor regresses it. +- Production change keeps legacy `MaxComputeScanNode.java` untouched (keep baseline, read-only + reference). diff --git a/plan-doc/tasks/designs/P4-T06d-FIX-WRITE-ROWS-design.md b/plan-doc/tasks/designs/P4-T06d-FIX-WRITE-ROWS-design.md new file mode 100644 index 00000000000000..6e7b6cd010cadf --- /dev/null +++ b/plan-doc/tasks/designs/P4-T06d-FIX-WRITE-ROWS-design.md @@ -0,0 +1,43 @@ +# P4-T06d · FIX-WRITE-ROWS — INSERT affected-rows 恒 0 → doBeforeCommit 回填 loadedRows + +> issue 6 / 6(**最后一个**),phase 4 写回正确性,sev=major,layer=fe-core。来源: `P4-cutover-fix-design.md` §FIX-WRITE-ROWS(:394-420,parent 无 critic 块——本 issue 首次对抗 review)+ review WRITE-P1/WRITE-C1。 +> 据当前代码树核实(行号校正)。 + +## Problem +翻闸后(SPI 事务模型,当前唯一 adopter=MaxCompute),对 PluginDriven 外表 `INSERT INTO ...` 数据被正确写入,但客户端返回 / `SHOW INSERT RESULT` / `fe.audit.log` 的 returnRows 恒为 `affected rows: 0`。触发条件:`connectorTx != null`(SPI 事务模型)的任意 INSERT。JDBC/auto-commit handle 模型(`connectorTx==null`)不受影响。可观察输出回归(数据不丢,行数判读错误)。 + +## Root Cause(行号据当前树) +- `PluginDrivenInsertExecutor.doBeforeCommit()`(`:146-150`,修前)只在 `writeOps != null && insertHandle != null` 时调 `finishInsert`。事务模型下 `insertHandle` 恒 null(`beforeExec():108-113` 事务模型早退,handle 仅 JDBC 分支 `:140` 创建)→ 整段跳过,`loadedRows` 永不赋值。 +- `loadedRows` 字段 `AbstractInsertExecutor.java:69`(`protected long loadedRows = 0`);非事务路径在 `:222` 由 `coordinator.getLoadCounters().get(DPP_NORMAL_ALL)` 赋值。事务模型 BE 的 MaxCompute sink 只经 `TMCCommitData.row_count` 上报,不更新 `num_rows_load_success`(DPP_NORMAL_ALL)→ 取回 0。 +- 下游 `BaseExternalTableInsertExecutor` 用 `loadedRows` 设 setOk/updateReturnRows → 全 0。 +- legacy 基线 `MCInsertExecutor.java:74-78` doBeforeCommit:`loadedRows = transaction.getUpdateCnt()` + `transaction.finishInsert()`。翻闸 restructure 把 finishInsert 等价物(connectorTx.commit 经 txn manager,onComplete)镜像了,**漏镜像 loadedRows 赋值**。历史误判 `P4-T05-T06-cutover-design.md:114`("doBeforeCommit ... null for MC ⇒ correctly skipped")——本设计显式推翻。 + +## Design +在 `doBeforeCommit()` 事务模型分支回填 `loadedRows`,镜像 legacy 可观察行为。**不扩任何 SPI**:`getUpdateCnt()` 全链路已就绪——`ConnectorTransaction.getUpdateCnt()`(default `:96` 返 0)→ `MaxComputeConnectorTransaction.getUpdateCnt()`(`:158-159` = `sum(TMCCommitData.getRowCount())`)。 +- 取法(a,parent 推荐):`connectorTx.getUpdateCnt()`——executor 现有字段在手,无需 `transactionManager.getTransaction(txnId)` 的可失败 lookup;值与 legacy 一致(同一 `TMCCommitData.row_count` 累加链)。 +- keyed on `connectorTx != null`(SPI 事务模型),非 hardcode maxcompute——任何未来事务模型 connector 自动受益;`connectorTx == null` 的 JDBC/auto-commit 路径**字节不变**(继续走 coordinator/DPP_NORMAL_ALL)。 +- 现有 `finishInsert` guard(`writeOps != null && insertHandle != null`)不动;新增分支独立。两分支**互斥**(`connectorTx != null` ⇔ `insertHandle == null`:事务模型从不开 per-statement insert handle),顺序无关。 +- 无 finishInsert 调用:事务模型的提交经 txn manager(onComplete)完成,doBeforeCommit 只补行数。 + +## Implementation Plan +- [fe-core] `PluginDrivenInsertExecutor.java` `doBeforeCommit()`:在 finishInsert guard 后新增 + `if (connectorTx != null) { loadedRows = connectorTx.getUpdateCnt();

No error, no warning. + +Two enabling conditions make the bug live: + +1. **Nereids upstream does NOT reject auto-inc for external (non-OLAP) tables.** The historical + claim in `P4-maxcompute-migration.md:117` ("nereids upstream already rejects") is FALSE for + auto-inc. `ColumnDefinition.validate(boolean isOlap, ...)` is the only nereids gate, and its + sole auto-inc check is line 666-667 — and that fires **only for generated columns** + (`generatedColumnDesc.isPresent()`), not plain auto-inc columns. There is no `isOlap==false` + path that rejects a bare auto-inc column. So an auto-inc column flows cleanly through nereids + analysis into the connector create-table request. +2. **The SPI carrier cannot represent auto-inc.** `ConnectorColumn` has no `isAutoInc` field, so + even if the connector wanted to reject it, the flag is invisible by the time it reaches + `validateColumns`. + +## Root Cause (confirmed file:line — cutover vs legacy) + +Verified against the actual code on branch `catalog-spi-05`: + +- **SPI carrier drops the flag.** `ConnectorColumn` + (`fe/fe-connector/fe-connector-api/.../ConnectorColumn.java:25-99`) has exactly 6 fields: + `name, type, comment, nullable, defaultValue, isKey` (lines 27-32). No `isAutoInc`. Two ctors: + 5-arg (`:34-37`, delegates to 6-arg with `isKey=false`) and 6-arg (`:39-47`). `equals`/`hashCode` + (`:73-93`) cover only those 6 fields. +- **Converter drops the flag.** `CreateTableInfoToConnectorRequestConverter.convertColumns` + (`fe/fe-core/.../connector/ddl/CreateTableInfoToConnectorRequestConverter.java:83-93`) builds + each `ConnectorColumn` from a `ColumnDefinition` passing `d.getName(), type, d.getComment(), + d.isNullable(), null, d.isKey()` — it reads `isKey()` but never reads `getAutoIncInitValue()`. + A column is auto-inc when `getAutoIncInitValue() != -1` (default `-1`, field decl + `ColumnDefinition.java:69`; getter `:651-652`; the `!= -1` semantics are also how `toSql` decides + to emit `AUTO_INCREMENT`, `:225-230`). +- **Connector validation cannot see it.** `MaxComputeConnectorMetadata.validateColumns` + (`fe/fe-connector/fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java:424-438`, called + from `createTable` at `:348` after the `tableExist` short-circuit) checks only: empty/null + (`:425-428`), duplicate name (`:431-433`), and representable type (`:436`, via + `MCTypeMapping.toMcType`). There is no auto-inc check because the flag was never carried. + +Net: auto-inc reaches the connector but is invisible there, so it is silently dropped. + +## Parity Reference (exact legacy code being mirrored) + +Legacy `MaxComputeMetadataOps.validateColumns` +(`fe/fe-core/src/main/java/org/apache/doris/datasource/maxcompute/MaxComputeMetadataOps.java:416-437`), +the auto-inc half is lines **422-425** (verified verbatim): + +```java +private void validateColumns(List columns) throws UserException { + if (columns == null || columns.isEmpty()) { + throw new UserException("Table must have at least one column."); + } + Set columnNames = new HashSet<>(); + for (Column col : columns) { + if (col.isAutoInc()) { // :422 + throw new UserException( // :423 + "Auto-increment columns are not supported for MaxCompute tables: " + col.getName()); // :424 + } // :425 + if (col.isAggregated()) { ... } // :426-429 OUT OF SCOPE (F31) + ... + } +} +``` + +We mirror the auto-inc branch (`:422-425`) exactly, including the error message text. + +**Out of scope (do NOT add):** the aggregation-column branch (`:426-429`).

All existing `new + ConnectorColumn(` call sites keep compiling and keep `isAutoInc=false`, so the 7 other connectors + (es/jdbc/hive/hudi/iceberg/paimon/trino) and all read-path producers are zero-break. +- It is minimal (Rule 2): one field + one ctor + one getter + equals/hashCode update in the SPI, + one arg in the converter, one `if` in the connector. Nothing speculative; no SPI method-signature + change (only an additive ctor). + +The `defaultValue`-carrier gap noted in the converter comment (`:87-89`) is unrelated and stays +untouched (Rule 3). + +## Implementation Plan (ordered, file-by-file) + +### 1. `fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorColumn.java` (SPI, additive) + +- Add field after `isKey` (`:32`): `private final boolean isAutoInc;` +- Keep the 5-arg ctor (`:34-37`) unchanged (still delegates to the 6-arg). +- Change the existing **6-arg** ctor (`:39-47`) so it **delegates** to the new 7-arg with + `isAutoInc=false` (preserves existing behavior for the 6-arg call sites — EsTypeMapping:185 + isKey=true, converter:90): + ```java + public ConnectorColumn(String name, ConnectorType type, String comment, + boolean nullable, String defaultValue, boolean isKey) { + this(name, type, comment, nullable, defaultValue, isKey, false); + } + ``` +- Add the new **7-arg** ctor (the only one that assigns all fields): + ```java + public ConnectorColumn(String name, ConnectorType type, String comment, + boolean nullable, String defaultValue, boolean isKey, boolean isAutoInc) { + this.name = Objects.requireNonNull(name, "name"); + this.type = Objects.requireNonNull(type, "type"); + this.comment = comment; + this.nullable = nullable; + this.defaultValue = defaultValue; + this.isKey = isKey; + this.isAutoInc = isAutoInc; + } + ``` + (The 5-arg ctor continues to call the 6-arg, which now reaches the 7-arg with `isAutoInc=false`.) +- Add getter after `isKey()` (`:69-71`): `public boolean isAutoInc() { return isAutoInc; }` +- Update `equals` (`:81-88`): add `&& isAutoInc == that.isAutoInc`. +- Update `hashCode` (`:90-93`): add `isAutoInc` to `Objects.hash(...)`. +- `toString` (`:95-98`): leave unchanged (optional per issue; auto-inc not part of the existing + textual contract — Rule 3, no speculative change). + +### 2. `fe/fe-core/src/main/java/org/apache/doris/connector/ddl/CreateTableInfoToConnectorRequestConverter.java` (passthrough) + +- In `convertColumns` (`:90-92`), pass the auto-inc flag as the new 7th arg: + ```java + out.add(new ConnectorColumn( + d.getName(), type, d.getComment(), + d.isNullable(), null, d.isKey(), d.getAutoIncInitValue() != -1)); + ``` + No new imports needed (`ColumnDefinition` already imported, `getAutoIncInitValue()` is on it). + +### 3. `fe/fe-connector/fe-connector-maxcompute/src/main/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadata.java` (validation, parity) + +- In `validateColumns` (`:430-437` loop body), add the auto-inc check FIRST inside the loop, + mirroring legacy ordering (`:422-425`): + ```java + for (ConnectorColumn col : columns) { + if (col.isAutoInc()) { + throw new DorisConnectorException( + "Auto-increment columns are not supported for MaxCompute tables: " + col.getName()); + } + if (!seen.add(col.getName().toLowerCase())) { + ... + ``` + `DorisConnectorException` is already imported (`:25`).

(Mirrors legacy branch 1 + the `!res` editlog gate.) +- `exists && !isIfNotExists()` → **delegate the error to the connector** (do not add an FE-side + throw). Rationale below. +- else (new) → unchanged: connector `createTable`, `logCreateTable`, `resetMetaCacheNames`, + `return false`. + +**Decision — non-`IF NOT EXISTS` existing-table error path (Rule 7 / Rule 2):** +Legacy raises `ERR_TABLE_EXISTS_ERROR` FE-side at `:184/:195`. The cutover connector already +raises on this case (`MaxComputeConnectorMetadata.java:343`, +`"Table '...' already exists in database '...'"`), which the override wraps to `DdlException` +at `:282-283`. To keep the change **minimal and surgical** and avoid a second source of truth +for "already exists", we do **not** add an FE-side `ErrorReport.reportDdlException` for the +existing-table check. Instead: +- We only short-circuit (skip the connector call) for the `IF NOT EXISTS` hit. +- For `exists && !isIfNotExists()` we let control fall through to the existing + `connector.createTable(...)` call, which throws → `DdlException` (today's behavior, unchanged). + +This means the FE-side existence probe is used **only** to decide the `IF NOT EXISTS` +short-circuit; the not-`IF NOT EXISTS` error stays exactly as it is today. Trade-off surfaced: +the legacy error code (`ERR_TABLE_EXISTS_ERROR`, MySQL 1050) differs from the connector's +generic `DdlException` message. That message divergence already exists on the cutover branch +today and is **out of scope** for this data-change fix; restoring the exact error code would +add FE-side error machinery for no behavioral parity benefit beyond the message text. Flagged +for cleanup, not fixed here. (If the orchestrator wants exact-message parity, see Open +Question.) + +Also update the stale Javadoc at `:256-261` that claims the override "conservatively assumes +creation happened and writes the edit log" — that statement is now false for the IF-NOT-EXISTS +existing-table path. + +# Implementation Plan + +All production changes in **one** file. One test file changed. No signature changes anywhere. + +### 1. `fe/fe-core/src/main/java/org/apache/doris/datasource/PluginDrivenExternalCatalog.java` + +**(a) Replace the stale Javadoc paragraph at `:257-261`** (the "void SPI / conservatively +assumes creation happened" paragraph) with one that documents the new IF-NOT-EXISTS parity: + +> The SPI `createTable` is `void` and the override has no `metadataOps`; this method therefore +> mirrors legacy `MaxComputeMetadataOps.createTableImpl`: when the table already exists and +> `IF NOT EXISTS` was given it returns `true` and skips the connector create + edit log + cache +> reset (so CTAS short-circuits instead of INSERTing into the existing table); otherwise it +> creates the table, writes the edit log, resets the cache, and returns `false`. + +**(b) Insert the existence pre-check** after the session is built (after `:277`) and before the +converter/connector call.

No other new imports +(`getTableHandle`/`isIfNotExists`/`getTableNullable` are all on already-imported types). + +### 2. `fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` + +Add tests in the `// ==================== CREATE TABLE ====================` section (see Test +Plan). No changes to the `TestablePluginCatalog` harness are required — it already exposes +`getDbNullable`/`getDbForReplay`/`resetMetaCacheNames` and mocks `metadata`. The only addition +is stubbing `db.getTableNullable(...)` and `metadata.getTableHandle(...)` per-test. + +No call-site changes anywhere (no signature change). + +# Blast Radius + +**Other connectors (es/jdbc/hive/hudi/iceberg/paimon/trino): ZERO break — proven.** +- No SPI signature change (Rule: additive-or-none). The fix calls only `getTableHandle`, which + is an *existing* `ConnectorTableOps` default returning `Optional.empty()` + (`ConnectorTableOps.java:36-40`). +- This override (`PluginDrivenExternalCatalog.createTable`) is reached **only** by + plugin-driven catalogs. jdbc/es/trino external catalogs route create-table through + `ExternalCatalog.createTable` → `metadataOps.createTable` (their `metadataOps` is non-null); + they never enter this override. (The test file's class Javadoc confirms: plugin catalogs have + `metadataOps == null`.) +- For a hypothetical future full-adopter connector that does **not** override `getTableHandle`, + `exists` collapses to `db.getTableNullable(...) != null` (FE-cache only). That is strictly + *more* conservative than legacy MaxCompute (it just may miss a remote-only table that the FE + cache hasn't seen), and never regresses the new-table path. No connector is broken. + +**Callers of the changed method:** +- `Env.createTable` (`Env.java:3749-3752`) → `catalogIf.createTable(info)`: now receives `true` + on the IF-NOT-EXISTS existing-table case. This is exactly the contract `Env.createTable`'s + own Javadoc promises — the caller `CreateTableCommand.java:103` `if (createTable(...)) return;` + now short-circuits as intended. No code change at the call site; behavior is the fix. +- Plain (non-CTAS) `CREATE TABLE IF NOT EXISTS` on an existing table: `CreateTableCommand.run` + non-CTAS branch (`:91`) calls `Env.createTable` and ignores the return — behavior is now + "no editlog, no SDK call" instead of "redundant editlog"; strictly an improvement, no visible + user effect. + +**Existing tests whose assertions must change: NONE (they are preserved, not changed).** +- `testCreateTablePassesRemoteDbNameToConverter` (`:315-341`): stubs neither `getTableNullable` + nor `getTableHandle`. With the harness, `db` is a Mockito mock → `getTableNullable` returns + `null`, and `metadata.getTableHandle(...)` returns `Optional.empty()` (Mockito default) → + `exists == false` → the new-table path runs unchanged → `convert(info, "DB1")` still invoked. + **Stays green.** +- `testCreateTableInvalidatesDbCacheUsingLocalNames` (`:353-389`): same — `exists == false` → + `metadata.createTable` called, editlog written with local names, `resetMetaCacheNames` on the + replay db. **Stays green.** (This is the regression guard for the new-table / common path.) +- `testCreateTableMissingDbThrows` (`:343-351`): `db == null` branch is untouched. **Stays green.** +- All `createDb`/`dropDb`/`dropTable` tests: untouched code paths. + +So we **add** assertions for the existing-table path; we **change** none. + +# Risk Analysis + +- **Extra remote round-trip on every CREATE TABLE.** `getTableHandle` for MaxCompute calls + `structureHelper.tableExist` *and* `getOdpsTable` (`MaxComputeConnectorMetadata.java:113-121`) + — one extra ODPS metadata fetch per create. Legacy `createTableImpl` did the same `tableExist` + probe (`:179`), so this is **parity, not a new cost** (legacy's `tableExist` was a remote + call too). The `getOdpsTable` inside `getTableHandle` is marginally heavier than a bare + existence check, but CREATE TABLE is rare and not latency-sensitive; acceptable. (Avoiding it + would require a `tableExists` SPI method — rejected per the No-SPI-change directive.) +- **Short-circuit skips the connector's own `IF NOT EXISTS` no-op.** We now never call + `connector.createTable` on the existing+ifNotExists path. The connector's branch + (`:337-341`) was *also* a pure no-op in that case, so no behavior is lost; we just decide it + FE-side (required to get the correct `return true`). +- **Local-vs-remote existence divergence.** If the FE cache is stale (table exists remotely but + not in cache), `getTableHandle` still catches it (remote probe). If it exists in cache but not + remotely (dropped out-of-band), `getTableNullable` catches it → we `return true` and skip + create. Legacy did the identical OR (`:179` remote OR `:189` local), so this is exact parity. +- **Error-message divergence on `exists && !IF NOT EXISTS`** (DdlException text vs legacy + `ERR_TABLE_EXISTS_ERROR`) — pre-existing on the cutover branch, explicitly out of scope, + flagged for cleanup. Fail-loud is preserved (it still throws). Rule 12 satisfied. +- **Mutation safety / no silent skip.** The new-table path is byte-for-byte the old behavior; + the only added branch is guarded by `exists && isIfNotExists()`. No path silently succeeds + that previously failed. + +# Test Plan + +## Unit Tests + +File: `fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` +Class: `PluginDrivenExternalCatalogDdlRoutingTest` (add to the CREATE TABLE section). + +**Test 1 — `testCreateTableIfNotExistsExistingTableReturnsTrueAndSkipsAllSideEffects`** +- Arrange: `db = mockExternalDatabase()`, `db.getRemoteName()` → `"DB1"`, + `catalog.dbNullableResult = db`; `info.isIfNotExists()` → `true`, + `info.getDbName()` → `"db1"`, `info.getTableName()` → `"t1"`; stub + `metadata.getTableHandle(session, "DB1", "t1")` → `Optional.of(mock(ConnectorTableHandle.class))`. +- Act: `boolean res = catalog.createTable(info);` +- Assert: + - `assertTrue(res, ...)` — WHY: a `false` here makes `CreateTableCommand:103` not short-circuit, + so CTAS INSERTs into the already-existing table (silent data change, DG-6). This is the + core regression guard. + - `verify(metadata, never()).createTable(any(), any())` — WHY: the connector create must be + skipped on the IF-NOT-EXISTS hit (it would only no-op; calling it is wasted + masks intent). + - `verify(mockEditLog, never()).logCreateTable(any())` — WHY: legacy writes editlog only when a + NEW table was created (`ExternalCatalog.java:1064` `if (!res)`); a redundant `OP_CREATE_TABLE` + on an existing table pollutes the journal. + - `assertEquals(0, catalog.resetMetaCacheNamesCount)` *(or* `verify(replayDb, never()).resetMetaCacheNames()` + if a replay db is stubbed)* — WHY: no metadata changed, so no cache invalidation; legacy's + `afterCreateTable` runs only on the `!res` branch. + +**Test 2 — `testCreateTableIfNotExistsExistingLocalTableReturnsTrue`** (local-cache arm of the OR) +- Arrange: `db.getRemoteName()` → `"DB1"`; `metadata.getTableHandle(session, "DB1", "t1")` + → `Optional.empty()` (remote says absent); `db.getTableNullable("t1")` → `mock(ExternalTable.class)` + (FE cache has it); `info.isIfNotExists()` → `true`. +- Act/Assert: `assertTrue(res)`, `verify(metadata, never()).createTable(...)`, + `verify(mockEditLog, never()).logCreateTable(...)`. +- WHY: legacy checks BOTH remote (`:179`) and local (`:189`); this guards the local arm so a + refactor that drops the `getTableNullable` probe (keeping only `getTableHandle`) goes red — + it encodes the case-sensitivity / stale-remote parity, not just "exists". + +**Test 3 (new-table regression guard) — covered by EXISTING +`testCreateTableInvalidatesDbCacheUsingLocalNames` (`:353-389`).** It already asserts the +new-table path: `metadata.createTable` called, editlog written with local names, +`resetMetaCacheNames` on replay db. Its implicit return value is `false`. We rely on it as the +"new table still creates + logs" guard (no duplication, Rule 2). Optionally add one explicit +line to that test: `assertFalse(catalog.createTable(info))` capture — but since it already +locks the side effects, adding a 4th near-identical test is redundant. + +**MUTATION CHECK (Rule 9):** +- One-line production revert: change the new branch back to the original unconditional tail — + i.e. delete the `if (exists && createTableInfo.isIfNotExists()) { return true; }` block (so the + method always falls through to `logCreateTable` + `resetMetaCacheNames` + `return false`). + → **Test 1 goes red** on every assertion (`assertTrue(res)` first: gets `false`; + `verify(never()).logCreateTable` fails: editlog written; `resetMetaCacheNamesCount` becomes 1). + This is precisely the DG-6 production bug, so the test cannot pass while the bug is present. +- Second mutation: change `exists = getTableHandle(...).isPresent() || getTableNullable(...) != null` + to drop the `|| getTableNullable(...) != null` arm. → **Test 2 goes red** (remote stub is + empty, so `exists` becomes `false`, falls into the new-table path, `createTable` gets called). + Encodes the local-cache parity intent. + +## E2E Tests + +`regression-test/suites/...` — the truth-gate is a live ODPS run (CI-skipped, per the standing +e2e policy; no e2e is exercised in CI). Intent to verify when a live ODPS env is available: + +1. `CREATE TABLE IF NOT EXISTS mc_existing AS SELECT * FROM src;` against a pre-existing + `mc_existing` → asserts the table's row count / contents are **unchanged** (no INSERT + occurred) and the statement returns OK. This is the end-to-end form of the silent-data-change + regression. (Pre-fix: rows from `src` get appended.) +2. `CREATE TABLE IF NOT EXISTS mc_new AS SELECT * FROM src;` for a fresh `mc_new` → table is + created and populated (new-table path intact). + +These belong alongside the existing MaxCompute CTAS / DDL suites; CI will skip the live-ODPS +suite. Note (Rule 12): UT alone cannot prove the absence of the downstream INSERT against a real +table — UT proves `createTable` returns `true` and the CTAS command's `if (...) return;` +short-circuits; the live e2e is what confirms no rows were written. diff --git a/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md b/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md new file mode 100644 index 00000000000000..5713f7c01f6dc5 --- /dev/null +++ b/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md @@ -0,0 +1,180 @@ +# [P4-T06e] FIX-DATETIME-PUSHDOWN-FORMAT (GAP0/1) — design + +> 来源：Batch-D 红线扩充对抗复审 workflow `wbw4xszrg`。用户定 **Fix（Tier 1，major correctness/perf）**。 +> 关联：legacy 对照 `MaxComputeScanNode.convertLiteralToOdpsValues:529-613`；fe-core 字面量来源 `ExprToConnectorExpressionConverter.convertDateLiteral:309-321`。 + +## Problem + +翻闸后，对 max_compute 表的 **DATETIME / TIMESTAMP / TIMESTAMP_NTZ** 列下推谓词坏。当 catalog 开启 `datetime_predicate_push_down`（默认开，见 `MCConnectorProperties.DEFAULT_DATETIME_PREDICATE_PUSH_DOWN`）时： + +```sql +-- 例：dt 为 DATETIME 列，session time_zone = 'Asia/Shanghai'（非 UTC） +SELECT * FROM mc.db.t WHERE dt = '2023-02-02 00:00:00'; +``` + +两条独立 delta（互不掩盖，须同修）： + +- **delta-1（format，perf + 可能错）**：谓词字面量被错误地序列化为 `LocalDateTime.toString()` 形态（`'T'` 分隔、变精度，如 `"2023-02-02T00:00"`），再喂给空格分隔、定长的 `DATETIME_3/6_FORMATTER` → + - **非 UTC session**：`LocalDateTime.parse` 抛 `DateTimeParseException` → 被顶层 `convert()` catch → **整棵 conjunct 树降为 `NO_PREDICATE`**（谓词永不下推 = 性能回归，全表扫 + BE 兜底过滤）。 + - **UTC session**：`convertDateTimezone` 短路返回未转换的 `"2023-02-02T00:00"` → 把 **malformed 字面量**推给 ODPS（`dt == "2023-02-02T00:00"`，结果未定：可能 ODPS 报错、可能匹配错/丢行）。 +- **delta-2（TZ source，丢行）**：source timezone 取 **project-region TZ**（由 endpoint URL 推），而 legacy 取 **session TZ**。当 session TZ ≠ project-region TZ 且 ≠ UTC 时，转换基准错位 → 推给 ODPS 的 UTC 字面量整体偏移 → **静默丢行 / 匹配错行**。仅 delta-1 修好后 delta-2 才会显形（否则谓词早已被丢）。 + +行正确性 + 性能双回归。仅 MaxCompute 暴露（唯一翻闸的 SPI 文件扫描连接器；`MaxComputePredicateConverter` 为 MC 专有类）。 + +## Root Cause（已核码确认） + +### delta-1：过早 stringify LocalDateTime + +| #

The + other six connectors (es/jdbc/hive/hudi/iceberg/paimon/trino) never override + `ConnectorSchemaOps.dropDatabase` (verified: only MaxCompute does) and never call the + SPI form (they go through their own `metadataOps`), so they are ZERO-break: the + default 4-arg simply forwards to their inherited (or absent) 3-arg behavior. +- Only `MaxComputeConnectorMetadata` overrides the 4-arg to cascade.

Connector: override the 4-arg to cascade +`fe/fe-connector/fe-connector-maxcompute/src/main/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadata.java:415-420` + +Decision on the existing 3-arg override: **fold the 3-arg into the 4-arg** to avoid two +methods that both touch `dropDb`. Replace the current 3-arg `dropDatabase` override with +the 4-arg override; the inherited `default` 3-arg will delegate into it. Concretely, +change the existing override signature from +`dropDatabase(ConnectorSession session, String dbName, boolean ifExists)` to +`dropDatabase(ConnectorSession session, String dbName, boolean ifExists, boolean force)` +and add the cascade: + +```java +@Override +public void dropDatabase(ConnectorSession session, String dbName, + boolean ifExists, boolean force) { + if (force) { + // ODPS schemas().delete() does NOT auto-cascade; enumerate and drop each + // table first (mirrors legacy MaxComputeMetadataOps.dropDbImpl force branch). + for (String tableName : structureHelper.listTableNames(odps, dbName)) { + try { + structureHelper.dropTable(odps, dbName, tableName, true); + } catch (OdpsException e) { + throw new DorisConnectorException("Failed to drop MaxCompute table '" + + tableName + "' during force-drop of database '" + dbName + + "': " + e.getMessage(), e); + } + } + } + structureHelper.dropDb(odps, dbName, ifExists); + LOG.info("dropped MaxCompute database {} (force={})", dbName, force); +} +``` + +Helper signatures confirmed present and already used in this class: +- `structureHelper.listTableNames(odps, dbName)` — used at `MaxComputeConnectorMetadata.java:102`. +- `structureHelper.dropTable(odps, dbName, tableName, true)` — used at `:398` + (single-table `dropTable`); declared `throws OdpsException` + (`McStructureHelper.java:73-74`), hence the try/catch wrapping into + `DorisConnectorException` exactly as the existing single-table `dropTable` override + does at `:399-401`. +- `structureHelper.dropDb(odps, dbName, ifExists)` — the existing terminal call (`:418`). + +Note on legacy skip-on-fail (`continue`): legacy logs+continues if it can't *resolve* +a Doris table wrapper, but its actual remote drop (`dropTableImpl`) is NOT swallowed. +Here there is no FE table-wrapper resolution step (we enumerate remote names directly), +so the only failure point is the remote `dropTable`, which we surface as +`DorisConnectorException` (fail loud, Rule 12) rather than silently continuing — this is +stricter than legacy only for the genuinely-failing-remote-drop case, which is the +correct fail-loud behavior. No imports change (`OdpsException`, `DorisConnectorException` +already imported, confirmed at `:25` and `:37`). + +### 3. fe-core caller: forward `force` +`fe/fe-core/src/main/java/org/apache/doris/datasource/PluginDrivenExternalCatalog.java:348` + +Change: +```java +connector.getMetadata(session).dropDatabase(session, dbName, ifExists); +``` +to: +```java +connector.getMetadata(session).dropDatabase(session, dbName, ifExists, force); +``` + +Also update the now-stale Javadoc at `:329-335` — replace the "force is intentionally +not forwarded" sentence with: "`force` is forwarded to the connector, which performs the +table cascade (mirroring legacy `MaxComputeMetadataOps.dropDbImpl`)." The surrounding +FE bookkeeping (`logDropDb` at :352, `unregisterDatabase` at :353) is unchanged — that +is the complete legacy db-level FE effect. + +### 4. FE routing test: update 3-arg stubs to 4-arg + add force-forwarding tests +`fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` + +The FE caller will now call the 4-arg SPI, so the existing Mockito verify/doThrow stubs +that reference the 3-arg `dropDatabase` must move to the 4-arg form: +- **:139** `Mockito.verify(metadata).dropDatabase(session, "db1", false)` → + `Mockito.verify(metadata).dropDatabase(session, "db1", false, false)`. +- **:151** `Mockito.verify(metadata, Mockito.never()).dropDatabase(Mockito.any(), Mockito.any(), Mockito.anyBoolean())` + → add a 4th matcher: `..., Mockito.any(), Mockito.anyBoolean(), Mockito.anyBoolean())`. +- **:167** `Mockito.doThrow(...).when(metadata).dropDatabase(Mockito.any(), Mockito.any(), Mockito.anyBoolean())` + → `..., Mockito.any(), Mockito.anyBoolean(), Mockito.anyBoolean())`. + +Add two new tests in the DROP DATABASE section (mock `ConnectorMetadata`, so the default +delegation is irrelevant — we assert the exact 4-arg call): +- `testDropDbForceForwardsForceTrueToConnector` — `dropDb("db1", false, true)` then + `verify(metadata).dropDatabase(session, "db1", false, true)`. +- `testDropDbNonForceForwardsForceFalseToConnector` — `dropDb("db1", false, false)` then + `verify(metadata).dropDatabase(session, "db1", false, false)`. + +### 5. Connector cascade test (NEW) +`fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadataDropDbTest.java` + +The maxcompute test module has junit-jupiter but **NO mockito** (confirmed: no mockito +in `fe-connector-maxcompute/pom.xml`, connector parent, or api pom; no test uses +`org.mockito`). So the test uses a **hand-written recording fake `McStructureHelper`** +(implements the interface, records call order) — matching how +`MaxComputeBuildTableDescriptorTest` constructs the metadata offline with `null` odps. +The cascade code never dereferences `odps` (it only passes it to the fake helper), so +`null` odps is safe. See Test Plan for the exact tests. + +# Blast Radius + +**SPI overriders of `ConnectorSchemaOps.dropDatabase`** (grep across `fe/fe-connector/`): +only two files — `ConnectorSchemaOps.java` (declaration) and +`MaxComputeConnectorMetadata.java` (the sole override). The other six connectors +(es/jdbc/hive/hudi/iceberg/paimon/trino) do NOT override it and do NOT call the SPI form +(their DROP DB goes through `metadataOps.dropDb` / +`ExternalCatalog.dropDb:1037` / `PaimonMetadataOps.java:158` / `HiveMetadataOps.java:162`, +none of which touch `ConnectorSchemaOps`). The new 4-arg is a `default` that delegates to +the 3-arg, so: +- es/jdbc/hive/hudi/iceberg/paimon/trino: ZERO source change, ZERO behavior change + (they never reach this method; even if they did, the default preserves 3-arg behavior). +- MaxCompute: only connector whose behavior changes, and only on the `force==true` + branch (non-force is byte-for-byte the prior `dropDb` call). + +**Production callers of the SPI `dropDatabase`**: exactly one — +`PluginDrivenExternalCatalog.java:348` (the FE caller being updated). No other +production call site exists (the many `dropDatabase` hits in the grep are Hive/Glue/Datalake +metastore *clients*, an unrelated method on a different interface). + +**Tests whose assertions must change (signature change forces this):** +- `PluginDrivenExternalCatalogDdlRoutingTest.java:139,151,167` — the three 3-arg + `dropDatabase` stubs/verifies, as itemized in Implementation Plan step 4. These are + compile-or-verify breaks caused directly by the FE caller switching to the 4-arg form; + they are mandatory. + +No SPI method is removed; the 3-arg `dropDatabase` stays (it is the delegation target). +No fe-core public signature changes — `PluginDrivenExternalCatalog.dropDb` already had +`force` in its signature. + +# Risk Analysis + +1. **Cross-module rebuild ordering.** SPI lives in `fe-connector-api`. A signature + *addition* (additive default) does not break binary compat for the existing 3-arg + callers, but the new call site in fe-core and the new override in maxcompute both + reference the 4-arg, so api + maxcompute + fe-core must be rebuilt together + (`-am`). Mitigation: build order in Test Plan. + +2. **dbName local-vs-remote name resolution (pre-existing, out of scope).** Legacy + enumerates via `dorisDb.getRemoteName()` and drops via `dorisTable.getRemoteName()`, + whereas `PluginDrivenExternalCatalog.dropDb` passes the **local** `dbName` straight to + the SPI (it does NOT remote-resolve, unlike the `dropTable`/`createTable` overrides at + :390/:279). The cascade therefore enumerates against whatever name the FE passes. For + a non-name-mapped catalog (the common case) local==remote and behavior is correct. + For a name-mapped catalog this is a latent bug — but it is **identical to and + inherited from the already-shipped non-force 3-arg path** (which also passes local + dbName to `dropDb`). Per Rule 3 (surgical) this fix does NOT widen scope to remote- + resolve dbName; doing so would change the existing non-force path too. Surfaced as an + open question (see below) and flagged for the DG-3/DG-4 DB-DDL triage batch. + +3. **Partial cascade on mid-loop failure.** If table N's remote drop throws, tables + 1..N-1 are already gone and the schema is NOT deleted (we throw before `dropDb`). + This is a fail-loud partial state — but it matches legacy's exposure (legacy's + `dropTableImpl` could equally throw mid-loop) and is the correct behavior vs silently + leaving residue. The DdlException surfaces to the user. + +4. **namespace-schema=false mode.** `ProjectTableHelper.dropDb` throws "not supported" + (`McStructureHelper.java:323-328`). With `force=true` in that mode, we now enumerate + + dropTable first, then hit the same "not supported" on `dropDb`. Net behavior is the + same terminal error as today (CREATE/DROP DB is unsupported without namespace-schema); + the extra table drops before the throw are harmless because that mode realistically + isn't used for DROP DB at all. No regression vs current. + +5. **Live ODPS truth-gate.** UT verifies routing + cascade ordering with fakes/mocks; + it cannot verify ODPS actually rejects non-empty `schemas().delete()`. That remains + the standing live-e2e truth gate (CI-skip). + +# Test Plan + +## Unit Tests + +### A. FE routing — `PluginDrivenExternalCatalogDdlRoutingTest` (fe-core) +File: `fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` +Class: `PluginDrivenExternalCatalogDdlRoutingTest` + +- **(edit) testDropDbRoutesToConnectorAndUnregisters** (:134) — change the :139 verify + to `dropDatabase(session, "db1", false, false)`.

WHY: guards that the + fix does NOT spuriously cascade a non-FORCE drop (over-correction would be a new bug). + +MUTATION check: reverting `PluginDrivenExternalCatalog.java:348` to pass a hardcoded +`false` (or back to the 3-arg form) makes **testDropDbForceForwardsForceTrueToConnector** +go red (verify sees `force=false`/no 4-arg call, not `true`). + +### B.

WHY (Rule 9): encodes the legacy parity requirement that + ODPS does NOT auto-cascade, so every table must be dropped first — the exact regression + DG-3 describes. MUTATION: removing the `if (force) { ...enumerate/dropTable... }` block + in `MaxComputeConnectorMetadata.dropDatabase` makes this red (log becomes just + `["dropDb:db1"]`). +- **forceFalseDoesNotEnumerateOrDropTables** — fake `listTableNames` returns + `["t1","t2"]` (would-be tables present); call `dropDatabase(session, "db1", false, + false)`; assert the log equals `["dropDb:db1"]` (no `dropTable`, no enumeration).

Post-cutover the same command throws before reaching the (fully +wired) write machinery. + +## Root Cause + +`allowInsertOverwrite` is a pure `instanceof` allow-list of *legacy* table classes. The cutover +replaced the concrete `MaxComputeExternalTable` with the generic `PluginDrivenExternalTable`, but +this gate was never extended to recognise the generic SPI table type. The lower OVERWRITE machinery +*was* extended (it already has a `UnboundConnectorTableSink` branch — see below), so this is a +classic "dispatch only half-wired": the entry gate rejects what the body already supports. + +### The lower machinery is already complete (one-gate change confirmed) + +Once the gate passes, the path is fully wired for the plugin/connector case: + +1. `run()` (`:157-160`) calls `InsertUtils.normalizePlan(...)`. For a `PluginDrivenExternalCatalog`, + the parsed `INSERT OVERWRITE` plan is an `UnboundConnectorTableSink` + (`UnboundTableSinkCreator.java:68-69, :108-110, :149-151` all map + `curCatalog instanceof PluginDrivenExternalCatalog` → `UnboundConnectorTableSink`; + `InsertUtils.normalizePlan` handles it at `InsertUtils.java:609-610`). +2. The non-OLAP branch at `run()` `:215-218` sets `partitionNames = []` (FE does not create temp + partitions for external tables), and the flow enters `insertIntoPartitions(...)` via `:241-279`. +3. `insertIntoPartitions` (`:345-444`) dispatches on the sink type. The + `UnboundConnectorTableSink` branch (`:420-440`) rebuilds the sink, creates a + `PluginDrivenInsertCommandContext`, sets `overwrite=true`, and copies the static-partition spec + from `sink.getStaticPartitionKeyValues()`. This is the genuine OVERWRITE wiring — it just is + never reached today. + +So the fix is a single gate edit. No change to the body, the sink, the context, or the translator. + +## Design + +### The change + +Add a `PluginDrivenExternalTable` branch to `allowInsertOverwrite`: + +```java +private boolean allowInsertOverwrite(TableIf targetTable) { + if (targetTable instanceof OlapTable || targetTable instanceof RemoteDorisExternalTable) { + return true; + } else { + return targetTable instanceof HMSExternalTable + || targetTable instanceof IcebergExternalTable + || targetTable instanceof MaxComputeExternalTable + || targetTable instanceof PluginDrivenExternalTable; + } +} +``` + +### Predicate choice — `instanceof PluginDrivenExternalTable` (Rule 7, Rule 2) + +The re-review (§NG-1 处置) phrased the predicate as "key on the SPI generic type; whether OVERWRITE +is supported is decided by whether downstream produces an `UnboundConnectorTableSink`." Examining the +actual code, those two phrasings collapse to the *same* predicate: + +- `UnboundTableSinkCreator` produces an `UnboundConnectorTableSink` **iff** + `curCatalog instanceof PluginDrivenExternalCatalog` (`:68`, `:108`, `:149`) — there is **no** + capability flag or table-level toggle in that decision. +- A `PluginDrivenExternalTable` always belongs to a `PluginDrivenExternalCatalog` (its ctor and all + metadata accessors cast `catalog` to `PluginDrivenExternalCatalog`). +- Therefore "table is `PluginDrivenExternalTable`" ⇔ "downstream produces `UnboundConnectorTableSink`" + ⇔ "the `:420-440` OVERWRITE branch will fire". The `instanceof` is the faithful, minimal encoding + of the report's "downstream produces UnboundConnectorTableSink" criterion. + +**Alternative considered — capability-gated** (`ConnectorCapability.SUPPORTS_INSERT`): +`ConnectorCapability` already exists and has `SUPPORTS_INSERT` (`ConnectorCapability.java:30`), and +`PluginDrivenExternalTable.supportsParallelWrite()` (`:78-85`) shows the established pattern for +reading capabilities. We could gate the branch on +`((PluginDrivenExternalCatalog) catalog).getConnector().getCapabilities().contains(SUPPORTS_INSERT)`. + +Rejected for this fix, because: +1. **It would not match the current contract.** No other downstream component (the sink creator, the + BindSink connector branch, `InsertUtils`) consults `SUPPORTS_INSERT` before producing/binding a + connector sink. Gating *only* the OVERWRITE gate on the capability would make OVERWRITE stricter + than plain INSERT, which is inconsistent and surprising. A capability check, if wanted, belongs in + the sink-creation layer (`UnboundTableSinkCreator`) so that INSERT and OVERWRITE share it — that + is a separate, broader change, out of scope for a regression fix. +2. **Rule 2 (simplicity) / Rule 11 (match conventions).** Every other arm of `allowInsertOverwrite` + is a bare `instanceof` (OlapTable / RemoteDoris / HMS / Iceberg / MaxCompute — `:316-321`); none + gates on a capability or write-support flag. A bare `instanceof PluginDrivenExternalTable` matches + the surrounding style exactly. If the underlying connector genuinely cannot write, the failure + surfaces deterministically deeper in the write path (BE / connector sink), exactly as it would for + plain INSERT today — the gate is not the right place to pre-empt that. +3. **The report's literal criterion is the `UnboundConnectorTableSink`, not a capability** — and that + is what `instanceof PluginDrivenExternalTable` encodes (see above equivalence). + +**Recommendation:** `instanceof PluginDrivenExternalTable`. This is the simplest predicate that is +*correct against the actual downstream dispatch* and consistent with both the existing arms of this +method and the FIX-PART-GATES decision① principle ("key on the SPI type, do not over-broaden"). Note +the contrast with FIX-PART-GATES decision①: there the override was *shared* by jdbc/es/trino/MC, so +an unconditional `true` would have flipped non-MC behavior, and the predicate had to be narrowed +(`!getPartitionColumns().isEmpty()`). Here the predicate already *is* type-scoped — `instanceof +PluginDrivenExternalTable` only fires for plugin tables — and the downstream is uniformly wired for +all of them, so no further narrowing is warranted or beneficial. + +### Shared-override / blast-radius note (jdbc/es/trino) + +`allowInsertOverwrite` is **not** an override shared across table classes — it is a private method of +`InsertOverwriteTableCommand` keyed on `instanceof`. Adding the branch only changes behavior for +tables that are `PluginDrivenExternalTable` (jdbc, es, trino-connector, max_compute after cutover). +For jdbc/es/trino this *enables* the OVERWRITE entry gate where it was previously rejected — but the +downstream is identical for all of them: they all flow through the same `UnboundConnectorTableSink` → +`PluginDrivenInsertCommandContext(overwrite=true)` branch (`:420-440`). If a given connector cannot +actually perform an overwrite, it fails at the connector/BE write layer with a connector-specific +error, exactly as a plain INSERT into a write-incapable connector does today. The gate is not the +behavioral firewall for "can this connector write" — the connector itself is. This is the same +semantics legacy had: legacy gated only on `instanceof MaxComputeExternalTable` because MC was the +only connector-style table; the generic replacement is `instanceof PluginDrivenExternalTable`. + +## Implementation Plan + +**File:** `fe/fe-core/src/main/java/org/apache/doris/nereids/trees/plans/commands/insert/InsertOverwriteTableCommand.java` + +**Method:** `allowInsertOverwrite(TableIf)` (`:315-323`). + +**Edit** — append one `instanceof` arm to the `else` return (`:319-321`): + +```java + return targetTable instanceof HMSExternalTable + || targetTable instanceof IcebergExternalTable + || targetTable instanceof MaxComputeExternalTable + || targetTable instanceof PluginDrivenExternalTable; +``` + +**Import to add:** +`import org.apache.doris.datasource.PluginDrivenExternalTable;` + +**Import placement / checkstyle (CustomImportOrder: doris → third-party → java; UnusedImports; +LineLength 120):** the new import is in the `org.apache.doris.datasource.*` block.

Insert it as the **first** line of that block, i.e. +immediately before `:29`. (Confirm against `checkstyle:check`; if the project's import comparator is +case-insensitive the line may instead sort after the `maxcompute` line — let checkstyle dictate the +exact slot.) + +No other edits. The branch body and all downstream wiring are unchanged. + +## Risk Analysis + +- **Blast radius — non-MC plugin connectors (jdbc/es/trino):** This change lets jdbc/es/trino-backed + `PluginDrivenExternalTable`s pass the OVERWRITE *entry* gate. Pre-cutover those were legacy + `JdbcExternalTable` / `EsExternalTable` / `TrinoConnectorExternalTable`, which were **never** in + `allowInsertOverwrite` — so for them this is a *new* code path being opened, not a parity + restoration. Mitigation/justification: the downstream is uniform (all plugin catalogs produce + `UnboundConnectorTableSink`), and a connector that cannot overwrite fails deterministically at the + bind/BE layer with a connector-specific error — the same place plain INSERT fails for a + write-incapable connector. The gate is intentionally not the per-connector write-capability check. + If product wants OVERWRITE locked down per-connector, that belongs in `UnboundTableSinkCreator` + (shared by INSERT + OVERWRITE), not here — flagged, out of scope. +- **Batch-D red-line interaction (🔴):** Batch-D plans to delete the legacy + `instanceof MaxComputeExternalTable` arm (`:321`) from this method + (`P4-batchD-maxcompute-removal-design.md` §2, file row for `InsertOverwriteTableCommand.java`). + That deletion is safe **only after** this fix adds the `PluginDrivenExternalTable` arm — otherwise + the gate loses *all* coverage for MaxCompute tables (legacy class is gone post-cutover anyway, and + the generic arm would not yet exist) and `INSERT OVERWRITE` breaks permanently. Ordering: this fix + must land *before* the Batch-D delete-branch edit for `:321`. **Doc-sync flag below.** +- **What can still fail at BE/live (real truth-gate):** This fix only proves the FE entry gate is + passable. The actual OVERWRITE execution (static-partition spec honored, partition replace + semantics, affected-rows, MC `INSERT OVERWRITE` vs `INSERT INTO ... OVERWRITE` mapping) is BE + + connector + ODPS, and per the re-review (§NG-1 note, §E#5/#6) the truth-gate is **live e2e against + real ODPS, which CI skips**. The re-review also flags adjacent write blockers (NG-2/NG-4 dynamic + partition GATHER/local-sort, NG-3 static-partition bind) that this fix does *not* address — a green + gate here does not imply a green end-to-end OVERWRITE until those are fixed and run live. + This fix is necessary-but-not-sufficient for working OVERWRITE; it removes the first (FE) blocker. + +## Test Plan + +### Unit Tests + +**Location:** new test class +`fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/insert/InsertOverwriteTableCommandTest.java` +(no existing unit test targets `allowInsertOverwrite` — verified; this is the package home of the +command under test). + +`allowInsertOverwrite(TableIf)` is `private` and field-independent (it inspects only its argument), +so invoke it directly via the project's established private-method test helper +`org.apache.doris.common.jmockit.Deencapsulation.invoke(instance, "allowInsertOverwrite", table)` +(pattern: `transaction/TableStreamOffsetTransactionTest.java:112`). Construct the command with any +minimal `LogicalPlan` (the ctor only requires a non-null `logicalQuery`; `allowInsertOverwrite` never +touches it — use a mock/stub `LogicalPlan` or a trivial unbound sink). Build the +`PluginDrivenExternalTable` with the mock-catalog pattern from +`PluginDrivenExternalTablePartitionTest` (`TestablePluginCatalog("max_compute", ...)` + a +`PluginDrivenExternalTable` anonymous subclass that no-ops `makeSureInitialized()`), so no Doris env +is required. + +**Test 1 — `allowInsertOverwriteAcceptsPluginDrivenTable` (the Rule-9 red-before / green-after test):** +- Arrange: a `PluginDrivenExternalTable` backed by a `max_compute` `TestablePluginCatalog`. +- Act: `boolean allowed = Deencapsulation.invoke(cmd, "allowInsertOverwrite", table);` +- Assert: `assertTrue(allowed, "INSERT OVERWRITE into a cutover MaxCompute (PluginDrivenExternalTable) must pass the gate; legacy MaxComputeExternalTable did")`. +- **Why it encodes intent (Rule 9):** it asserts the *business* invariant "cutover MaxCompute tables + retain INSERT OVERWRITE support that legacy had" — not merely "method returns a boolean". +- **Mutation / red-before proof:** remove the new `|| targetTable instanceof PluginDrivenExternalTable` + arm (i.e. revert the production change) → `allowInsertOverwrite` returns `false` for a + `PluginDrivenExternalTable` → this assertion goes **red**. With the arm present it is green. This is + the loop's red-before/green-after gate. + +**Test 2 (optional parity guard) — `allowInsertOverwriteStillRejectsUnsupportedType`:** +- Arrange: a `TableIf` that is none of the allow-listed types (e.g. a mock `TableIf`, or any + internal table type not in the list). +- Assert: `assertFalse(...)`. +- **Why:** pins that the new arm did not accidentally broaden to "all external tables" — a mutation + that replaced the targeted `instanceof` with an unconditional `true` would make this red.

This is heavier (needs more of `run()`'s collaborators) and is +not required — Test 1 already gives the deterministic red-before/green-after gate. Prefer Test 1 + +Test 2 for the loop. + +**Out of scope for this loop (state explicitly):** end-to-end `INSERT OVERWRITE` execution against +real ODPS (`external_table_p2/maxcompute/*`). Per §Risk, that is the real truth-gate but requires +live credentials and is CI-skipped; it is not part of this fix's unit-test loop. + +--- + +# Round 2 revision (2026-06-07) — narrow predicate via SPI capability (user decision = Option A) + +**Why revised:** round-1 clean-room adversarial review (`w5ke8sjaq`) confirmed (2/2) that the bare +`instanceof PluginDrivenExternalTable` predicate also admits **JDBC** (which is `PluginDrivenExternalTable` +post-cutover, `supportsInsert()=true` but `getWriteConfig` never propagates the overwrite flag) → +`INSERT OVERWRITE` **silently degrades to a plain INSERT (data loss)**.

This +is the write-path face of the recurring "half-wired dispatch" (re-review §C domain-6): the read/DDL +dispatch was generalized, the write *distribution* was not. + +## Design + +### Two orthogonal connector signals → two capabilities + +The legacy 3-branch needs exactly two connector-declared facts, which I map to **`ConnectorCapability` +enum** values read through `connector.getCapabilities()` — the *same* mechanism the sibling +`supportsParallelWrite()` already uses (read in this very method), so both reads are uniform and +require no `ConnectorSession`/metadata construction in the planner property-derivation hot path: + +1. **`SUPPORTS_PARALLEL_WRITE`** (already exists, `ConnectorCapability.java:51`) — "multiple + concurrent writers are safe." Drives the non-partition / all-static → `SINK_RANDOM_PARTITIONED` + branch. **MaxCompute must now declare it** (fixes NG-4). Read via the existing + `PluginDrivenExternalTable.supportsParallelWrite()`. +2. **`SINK_REQUIRE_PARTITION_LOCAL_SORT`** (NEW enum value) — "dynamic-partition writes must be + hash-distributed and locally sorted by partition columns" (the MaxCompute Storage-API streaming + constraint). Drives branch-1. **MaxCompute declares it** (fixes NG-2). Read via a new + `PluginDrivenExternalTable.requirePartitionLocalSortOnWrite()`. + +Default for the new capability is **absent/false** → no behavior change for any other connector +(jdbc/es/trino: neither capability → still GATHER), mirroring the FIX-OVERWRITE-GATE +default-false-opt-in philosophy. The two capabilities are intended to be declared **together** by a +partition-writing connector (hash distribution is inherently parallel); the sink does not force that +pairing (branch-1 keys only on the local-sort capability, faithful to legacy's unconditional +dynamic→hash+sort), but the design note records the intended pairing. + +### The fe-core sink logic — **critical correction vs legacy: index by `cols`, not full-schema** + +> ⚠️ **SUPERSEDED by P0-3 / FIX-BIND-STATIC-PARTITION ([D-030], 2026-06-07).** This section's "index by +> `cols`" decision was **reverted to legacy full-schema indexing**. Reason: P0-3 makes +> `bindConnectorTableSink` project the child to **full-schema** order for positional-write connectors +> (MaxCompute, gated by capability `SINK_REQUIRE_FULL_SCHEMA_ORDER`), so `child().getOutput()` is again +> aligned with `table.getFullSchema()` — *not* `cols` (cols excludes static partition cols and may be +> user-reordered). `cols`-indexing silently shuffled by the wrong column in the partial-static and +> reordered-explicit-list cases. The "`cols.size() == child output size`" invariant below holds only for +> the non-positional (JDBC/ES) path. See `reviews/P4-T06e-FIX-BIND-STATIC-PARTITION-review-rounds.md`. + +The generic sink's `getRequirePhysicalProperties()` reproduces the legacy 3-branch, **but the +partition-column → child-output index mapping MUST differ from legacy.** This is the single most +important correctness point of this fix: + +- Legacy `bindMaxComputeTableSink` (`BindSink.java:904-906`) projects the child to **full-schema** + order (`getOutputProjectByCoercion(table.getFullSchema(), ...)`), so legacy + `PhysicalMaxComputeTableSink` can index `child().getOutput().get(fullSchemaIdx)`. +- The generic `bindConnectorTableSink` (`BindSink.java:949-950`) projects the child to **`bindColumns`** + order (`getOutputProjectByCoercion(bindColumns, ...)`), where `bindColumns == boundSink.getCols()`, + and enforces `cols.size() == child.getOutput().size()` (`:941`). So for the generic sink + `child().getOutput().get(i)` corresponds to **`cols.get(i)`**, NOT to `fullSchema.get(i)`. + +Therefore the generic sink finds each partition column by its index **in `cols`** and reads the +aligned child output slot at the same index: + +```java +@Override +public PhysicalProperties getRequirePhysicalProperties() { + if (!(targetTable instanceof PluginDrivenExternalTable)) { + return PhysicalProperties.GATHER; + } + PluginDrivenExternalTable table = (PluginDrivenExternalTable) targetTable; + + // Branch 1 — dynamic-partition write that the connector requires to be hash-distributed and + // locally sorted by partition columns (MaxCompute Storage API streams partition writers and + // errors on unsorted multi-partition data — mirrors legacy PhysicalMaxComputeTableSink). + if (table.requirePartitionLocalSortOnWrite()) { + Set partitionNames = table.getPartitionColumns().stream() + .map(Column::getName).collect(Collectors.toSet()); + if (!partitionNames.isEmpty()) { + // Index by cols (== child output alignment for the connector sink), NOT full schema. + List partitionColIdx = new ArrayList<>(); + for (int i = 0; i < cols.size(); i++) { + if (partitionNames.contains(cols.get(i).getName())) { + partitionColIdx.add(i); + } + } + if (!partitionColIdx.isEmpty()) { // a partition col present in cols == dynamic write + List exprIds = partitionColIdx.stream() + .map(idx -> child().getOutput().get(idx).getExprId()) + .collect(Collectors.toList()); + DistributionSpecHiveTableSinkHashPartitioned shuffleInfo = + new DistributionSpecHiveTableSinkHashPartitioned(); + shuffleInfo.setOutputColExprIds(exprIds); + List orderKeys = partitionColIdx.stream() + .map(idx -> new OrderKey(child().getOutput().get(idx), true, false)) + .collect(Collectors.toList()); + return new PhysicalProperties(shuffleInfo) + .withOrderSpec(new MustLocalSortOrderSpec(orderKeys)); + } + // partition cols exist but none in cols == all-static: fall through. + } + } + + // Branch 2/3 — non-partition or all-static: parallel writers if the connector supports it. + if (table.supportsParallelWrite()) { + return PhysicalProperties.SINK_RANDOM_PARTITIONED; + } + return PhysicalProperties.GATHER; +} +``` + +Result mapping: + +| table / write shape | caps declared | output | legacy parity | +|---|---|---|---| +| MaxCompute, dynamic partition | both | hash(part) + local-sort(part) | ✅ = legacy branch-1 | +| MaxCompute, all-static partition | both | `SINK_RANDOM_PARTITIONED` | ✅ = legacy branch-2 | +| MaxCompute, non-partitioned | both | `SINK_RANDOM_PARTITIONED` | ✅ = legacy branch-3 | +| jdbc / es / trino | none | `GATHER` | ✅ unchanged | + +### Why no change is needed in `RequestPropertyDeriver` + +`RequestPropertyDeriver.visitPhysicalConnectorTableSink():212-227` already routes correctly: +`GATHER → GATHER`; else (with `enableStrictConsistencyDml`, default **true** — +`SessionVariable.java:1566`) `→ getRequirePhysicalProperties()` to children. So once +`getRequirePhysicalProperties()` returns hash+local-sort, the deriver enforces it (inserts the +shuffle + local sort) exactly as it does for legacy `visitPhysicalMaxComputeTableSink():180-188`. The +non-strict (`enable_strict_consistency_dml=false`) path pushes `ANY` for **both** legacy MC and the +generic connector sink — i.e. it drops the requirement identically in legacy and cutover, so it is a +pre-existing parity, not a regression introduced here. (A user who turns off strict-consistency DML +loses local-sort on dynamic partitions in legacy too; default-on covers the common case.) + +### Known minor divergence — `ShuffleKeyPruner` (documented, not fixed here) + +`ShuffleKeyPruner.visitPhysicalConnectorTableSink():286-295` lacks the non-strict short-circuit that +`visitPhysicalMaxComputeTableSink():272-283` has. In the **default strict** mode both compute +`childAllowShuffleKeyPrune = required.equals(ANY)` → `false` for a dynamic-partition write → **identical +behavior**. They diverge **only** when `enable_strict_consistency_dml=false`: legacy prunes shuffle keys +(`true`), generic does not (`required` is hash+sort ≠ `ANY` → `false`). The generic path therefore +prunes **less** (more conservative) — a missed optimization, never a correctness issue, and it is +**pre-existing** (the generic branch already differs; this fix does not introduce it). Recorded as a +minor deviation; aligning it would touch the shared connector branch for jdbc/es and is out of scope. + +### Coupling with P0-3 (FIX-BIND-STATIC-PARTITION) — correct either way, fully exercised only after P0-3 + +The dynamic/static detection reads `cols` and relies on the contract *"static partition columns are +excluded from `cols`"* — the same contract legacy `getRequirePhysicalProperties()` relies on (legacy +`bindMaxComputeTableSink:876-879` excludes them). The generic `bindConnectorTableSink` does **not** yet +exclude them (that is the P0-3 bug, NG-3). Consequences, both **safe**: + +- `INSERT INTO mc PARTITION(p='x') SELECT ` (no column list, all-static): today + this **fails at bind** (`cols` includes `p`, child output excludes it → `:941` count mismatch + throws) — so `getRequirePhysicalProperties()` is **never reached**. After P0-3, `cols` excludes the + static `p` → branch falls through to `SINK_RANDOM_PARTITIONED`. ✅ either way. +- `INSERT INTO mc PARTITION(p) SELECT ... , p_val` (dynamic): `p` is in `cols` → branch-1 + hash+local-sort. ✅ today and after P0-3. +- Mixed `PARTITION(p1='x', p2) SELECT ...`: after P0-3, `cols` excludes static `p1`, includes dynamic + `p2` → hash+sort by `p2` only. Legacy hashes+sorts by `{p1,p2}` but `p1` is a projected constant, so + `{p2}` ≡ `{p1,p2}` for grouping. ✅ functionally equivalent. + +So **this fix is correct regardless of P0-3 ordering**; it is merely not *exercised* for the all-static +no-column-list shape until P0-3 lands.

Construct the sink with the project's established pattern (memory +`catalog-spi-fe-core-test-infra`): `Mockito.mock(PhysicalConnectorTableSink.class, CALLS_REAL_METHODS)` +to skip the ctor, `Deencapsulation.setField(sink, "targetTable"/"cols", ...)` to inject finals, and +`Mockito.doReturn(childPlan).when(sink).child()` (childPlan = a mock `Plan` whose `getOutput()` +returns hand-built `SlotReference`s aligned 1:1 with `cols`). The `PluginDrivenExternalTable` is built +with the `TestablePluginCatalog` + `tableWithCacheValue` pattern from +`PluginDrivenExternalTablePartitionTest`, and its mock `Connector.getCapabilities()` is stubbed per +case.

Assert result distribution is `DistributionSpecHiveTableSinkHashPartitioned` + whose `getOutputColExprIds()` equals the ExprId of the **cols-position** child slot for `part`, AND + the order spec is `MustLocalSortOrderSpec` over that same slot. **Why it encodes intent (Rule 9):** + asserts the business invariant "dynamic-partition MaxCompute writes are grouped per partition so the + Storage API does not hit 'writer has been closed'." **Mutation:** revert + `getRequirePhysicalProperties()` to the old `supportsParallelWrite? RANDOM : GATHER` → result is + `SINK_RANDOM_PARTITIONED` (no order spec) → red. Also: an index-by-full-schema mutation maps to the + wrong/out-of-range slot → red. +- **T2 `allStaticPartitionWriteUsesRandomPartitioned`:** partitioned table, both caps, `cols` + **excludes** all partition cols → assert `SINK_RANDOM_PARTITIONED` (no order spec). Pins the + static-vs-dynamic detection (mutation dropping the `partitionColIdx.isEmpty()` fall-through would + red). +- **T3 `nonPartitionedWriteUsesRandomWhenParallel`:** no partition cols, both caps → assert + `SINK_RANDOM_PARTITIONED`. (NG-4 parity for non-partitioned tables.) +- **T4 `nonParallelConnectorGathers`:** table with **no** capabilities (jdbc-like) → assert `GATHER`. + Guards that the change did not broaden parallel/sort behavior to capability-less connectors. + +### E2E Tests + +Out of scope for this loop (per the round process: compile+UT, no e2e). The real truth-gate — +`INSERT` across **multiple dynamic partitions** against real ODPS asserting no `"writer has been +closed"` + parallel throughput on non-partitioned writes — requires live ODPS credentials and is +CI-skipped.

The conclusion (fix is legacy-equivalent and safe) is unchanged and verified, but the supporting statement 'grep 全证实 ... 只 流向两处' is wrong and should be corrected. +- Minor: the design says the fix mirrors legacy MaxComputeScanNode.java:659 length=-1; verified accurate -- legacy constructor MaxComputeSplit(BYTE_SIZE_PATH, splitIndex, -1, splitByteSize, ...) puts -1 in arg3 (length) and splitByteSize in arg4 (fileLength, unread by BE). Connector after fix is byte-exact (setSize=-1, setStartOffset=splitIndex, path='[ splitIndex , -1 ]'). No correction needed to the core claim. + +**遗漏(gaps)**: +- Risk analysis omits a third consumer of getLength(): PluginDrivenSplit.java:42 passes scanRange.getLength() into the FileSplit.length field. The design's repeated claim that splitByteSize/getLength flows ONLY into setPath(:120) and setSize(:122) ('grep fully confirms') is factually incomplete. FileSplit.length is consumed downstream by FederationBackendPolicy.java:499 (primitiveSink.putLong(split.getLength()) in consistent-hash backend assignment) and FileQueryScanNode.java:430 (totalFileSize += split.getLength()). After the fix these see -1 instead of 268435456 -- which is BENIGN because legacy MaxComputeSplit also used length=-1 (the current buggy cutover diverges from legacy here too), so the fix actually improves parity. But the design must update the grep claim and add these consumers to the impact analysis instead of asserting 'only two places'. +- Test Plan does not acknowledge that the named E2E suite (regression-test/suites/external_table_p2/maxcompute/test_external_catalog_maxcompute.groovy) is an external_table_p2 suite requiring live MaxCompute/ODPS credentials, so it will be skipped in normal CI. The design frames it as 'the most direct coverage', but the only CI-runnable automated guard is the proposed UT. This should be stated explicitly so the fix is not merged believing E2E runs unattended. +- The design scopes out (correctly) the broader read-path descriptor population, but for the reviewer's checklist: the JNI scanner requires TIME_ZONE (MaxComputeJniScanner.java:139 Objects.requireNonNull on 'time_zone'), and BE max_compute_jni_reader.cpp:62-77 does NOT set time_zone in the properties map -- it must arrive via mc_desc->properties()/endpoint. Whether the cutover descriptor carries time_zone/project/quota/endpoint correctly is the separate READ-P1 blocker; this fix neither helps nor regresses it, but the split-size fix alone will NOT yield correct reads if READ-P1 is unfixed. The design states this dependency but does not call out the time_zone requirement specifically. + +**额外风险**: +- Backend-assignment determinism: FederationBackendPolicy.java:499 hashes split.getLength() into the consistent-hash placement. Changing length from 268435456 to -1 for every byte_size split changes which backend each split lands on (vs the current buggy cutover). This is invisible/benign for correctness and matches legacy, but means a before/after A-B comparison of split-to-BE placement on the SAME cutover build will differ -- worth noting so it is not mistaken for a regression during validation. +- FileQueryScanNode.java:430 accumulates totalFileSize += getLength(); with length=-1 per split this drives totalFileSize negative for byte_size scans (one -1 per split). This is a pre-existing legacy behavior (legacy also had -1) used only for stats/cost/logging, not correctness, but it propagates to profile/explain numbers and any cost-based heuristic keyed on totalFileSize.

Step 1 says insert the new import 'between :51 InternalCatalog and :52 maxcompute.MaxComputeExternalCatalog, 按字母序'. Actual lines are 48-53 (off by two), and ASCII-case-sensitive ordering puts uppercase 'PluginDrivenExternalCatalog' (P) BEFORE lowercase sub-package imports 'hive.' / 'iceberg.' / 'maxcompute.' / 'paimon.'. Correct position is immediately after line 49 (org.apache.doris.datasource.InternalCatalog) and BEFORE line 50 (org.apache.doris.datasource.hive.HMSExternalCatalog) — i.e. grouped with the top-level datasource.* classes, not after the sub-packages. The stated placement would put it after hive/iceberg and Checkstyle CustomImportOrder would reject it. +- Line-number anchors throughout are off by two for the import region (design cites :51/:52 for InternalCatalog/MaxComputeExternalCatalog; actual is :49/:52). The method/branch anchors (paddingEngineName 896-918, MC branch 912, checkEngineWithCatalog 376-393, MC branch 390) are accurate; only the import-region anchors drift. Minor but the import-region drift directly produces the wrong-placement error above. + +**遗漏(gaps)**: +- E2E assertion is factually wrong and would FAIL even with a correct fix. The design's proposed supplementary assertion 'SHOW CREATE TABLE 输出包含 ENGINE=maxcompute' contradicts actual rendering. SHOW CREATE TABLE renders ENGINE= + table.getEngineTableTypeName() (Env.java:4283-4284), and PluginDrivenExternalTable.getEngineTableTypeName() (PluginDrivenExternalTable.java:232-233) returns TableType.MAX_COMPUTE_EXTERNAL_TABLE.name() == 'MAX_COMPUTE_EXTERNAL_TABLE'. The recorded baseline regression-test/data/.../test_max_compute_create_table.out line 3 confirms 'ENGINE=MAX_COMPUTE_EXTERNAL_TABLE', not 'ENGINE=maxcompute'. The design conflates analysis-time engineName ('maxcompute', used for DDL padding/validation) with display-time getEngineTableTypeName ('MAX_COMPUTE_EXTERNAL_TABLE'). The existing qt_test1_show_create_table already covers the regression correctly; the proposed extra assertion must be dropped. +- UT feasibility detail omitted: both paddingEngineName (line 899) and checkEngineWithCatalog (line 383) re-fetch the catalog via Env.getCurrentEnv().getCatalogMgr().getCatalog(ctlName) by NAME — they ignore any directly-constructed catalog object. The UT plan says 'construct a PluginDrivenExternalCatalog so getType()==max_compute' but never states it must be registered into CatalogMgr (or CatalogMgr mocked) for the by-name lookup to return it. As written the UT would hit the real CatalogMgr and not find the test catalog. +- CTAS path benefits but is unmentioned: validateCreateTableAsSelect (line 926) also calls paddingEngineName, so CTAS into a max_compute PluginDriven catalog is equally broken pre-fix and equally fixed. The design scopes only plain CREATE TABLE and never lists CTAS as a covered scenario or a test target, leaving a verification gap. +- No UT/E2E asserts the checkEngineWithCatalog mirror actually had a behavior change. The design claims the explicit-ENGINE consistency check is 'silently bypassed' pre-fix, but provides no failing-then-passing test that a wrong explicit ENGINE (e.g. ENGINE=hive on a max_compute catalog) is rejected only after the fix. Without it the mirror branch is untested against its WHY (violates Rule 9: the test could pass with the branch absent). + +**额外风险**: +- Root-cause analysis, central type-string mapping, and both target sites are otherwise CORRECT and verified: getType() returns lowercase 'max_compute' (CatalogFactory.java:90 toLowerCase + :100 putIfAbsent, :235-239 getType), the same key PluginDrivenExternalTable.getEngine()/getEngineTableTypeName() switch on; ENGINE_MAXCOMPUTE='maxcompute' (:125); and the warning against reusing TableType.MAX_COMPUTE_EXTERNAL_TABLE.toEngineName() is valid — that enum is NOT in the toEngineName() switch (TableIf.java) and returns null. The fix's destination is real: MaxComputeConnectorMetadata.createTable IS implemented (line 283), so padding the engine genuinely reaches a working createTable, not just a deferred failure. +- default-branch behavior for jdbc/es/trino is correctly non-regressive: pre-fix those catalogs already hit the same 'Current catalog does not support create table' throw at line 915, and ConnectorTableOps.createTable default also throws 'CREATE TABLE not supported' (line 66). So the helper's default-throw preserves their status quo — no new breakage, as claimed. +- Follower replay / master sync is NOT a concern for this fix (prompt flagged it): engine padding is analysis-time on the receiving FE; persistence uses logCreateTable edit log (PluginDrivenExternalCatalog.java:279) independent of engineName. No replay change needed. +- Batch-D ordering dependency is real and correctly flagged: P4-batchD-maxcompute-removal-design.md:100 plans to delete both instanceof MaxComputeExternalCatalog branches in CreateTableInfo; if Batch D runs without first landing the PluginDriven branch, no-ENGINE CREATE TABLE is permanently broken. The keep-set / commit-ordering note is warranted. Confirmed UnboundTableSinkCreator (CTAS/INSERT sink) already has PluginDrivenExternalCatalog branches (:68/:108/:149) from T06c — so CreateTableInfo really is the last unwired analysis-time CREATE TABLE gate, supporting the design's scoping. +- Latent fragility (acknowledged by design): two now-parallel switch-on-getType() tables (CreateTableInfo helper + PluginDrivenExternalTable.getEngine/getEngineTableTypeName) must stay in sync if SPI_READY_TYPES keys change. Acceptable given existing code already accepts this risk, but a future jdbc/es full-adopter will require touching both — worth the cross-reference comment the design suggests. + +--- + +### FIX-DDL-REMOTE — DDL 远端名解析 — CREATE/DROP TABLE 用 getRemoteName/getRemoteDbName 再发 connector + +- **Problem**: 翻闸到 `PluginDrivenExternalCatalog` 后，对启用了名映射的 catalog（`lower_case_meta_names=true` / `lower_case_database_names=1` 或 `2` / `meta_names_mapping`，使本地展示名 ≠ ODPS 远端真名）执行 `CREATE TABLE` / `DROP TABLE` 时，FE 把**本地名**原样透传给连接器，连接器再原样喂给 ODPS SDK。用户可见症状： + - `CREATE TABLE`：在错误大小写/映射后的库名下建表，或建到不存在的库报错。 + - `DROP TABLE`：`getTableHandle` 用本地小写/映射名查 ODPS 定位不到真实表 → `IF EXISTS` 静默不删（残表）、非 `IF EXISTS` 误报“表不存在”；极端情况删错对象。 + - 触发条件：catalog 属性开启上述任一名映射，且本地名与远端名不一致。未开映射时本地名==远端名，行为无差异（解释为何 gate/默认 e2e 未暴露）。这是 legacy 可用、翻闸即坏的**数据正确性回归**。 + +- **Root Cause**: + - CREATE：`fe/fe-core/.../PluginDrivenExternalCatalog.java:267-268` `CreateTableInfoToConnectorRequestConverter.convert(createTableInfo, createTableInfo.getDbName())` 传**本地** dbName；converter `fe/fe-core/.../connector/ddl/CreateTableInfoToConnectorRequestConverter.java:63-64` 用该 dbName 并直接 `info.getTableName()`（本地表名）。连接器 `fe/fe-connector/.../MaxComputeConnectorMetadata.java:285-286` 把 `request.getDbName()/getTableName()` 原样喂 `structureHelper.tableExist`/`createTableCreator`→ODPS。 + - DROP：`PluginDrivenExternalCatalog.java:357-359` 用本地 `dbName`/`tableName` 调 `metadata.getTableHandle`；连接器 `MaxComputeConnectorMetadata.java:104,346-347` 把本地名原样喂 SDK。 + - Legacy 基线（须 mirror）：`fe/fe-core/.../datasource/maxcompute/MaxComputeMetadataOps.java` — createTableImpl `:179`/`:219` 用 `db.getRemoteName()` 作 dbName（表名保持原始 `createTableInfo.getTableName()`，**legacy CREATE 不对表名做 remote 解析**，因为表尚不存在、无本地→远端映射）；dropTableImpl `:266-267` 用 `dorisTable.getRemoteDbName()`（= `db.getRemoteName()`）与 `dorisTable.getRemoteName()`。 + - 名映射来源：`fe/fe-core/.../ExternalCatalog.java:548-560` buildMetaCache 令 localName≠remoteName；`ExternalDatabase.getRemoteName():407-409`、`ExternalTable.getRemoteName():166-168`、`ExternalTable.getRemoteDbName():535-536`。 + - 注意 createDb/dropDb 不在本 issue 范围：legacy 的实际 SDK 调用对库名也用**原始本地名**（createDbImpl `:122`、dropDbImpl 实删 `:156`），仅 dropDbImpl 的 force 级联枚举用 `getRemoteName()`（属另一发现 DDL-P2）。故本 fix 只动 CREATE TABLE 的 db 名 + DROP TABLE 的 db/table 名。 + +- **Design**: remote 解析放 **FE（`PluginDrivenExternalCatalog`）**，与现有读路径 `getRemoteName` 用法、与 base `ExternalCatalog.dropTable:1119-1131`（先 `getDbNullable` 再 `db.getTableNullable` 取 dorisTable）一致；**不扩展 SPI**、不改连接器（连接器继续把 handle 里的名字当“已是远端名”原样发 SDK，契约保持“FE 负责 local→remote”）。这是通用插件层缺口（任何 full-adopter 都需），但实现 **keyed on PluginDriven 的通用 `ExternalDatabase`/`ExternalTable` getRemoteName API，非 hardcode maxcompute**。 + - createTable override：解析 db 远端名后传给 converter。最小改动用现有 converter 第二参（`convert(info, dbName)` 注释已写“caller may normalize case”）—— + `ExternalDatabase db = getDbNullable(createTableInfo.getDbName());`（db==null 抛 `DdlException("Failed to get database ...")`，mirror legacy `MaxComputeMetadataOps:172-176` 与 base `ExternalCatalog:1120-1122`），随后 `convert(createTableInfo, db.getRemoteName())`。表名保持 converter 内 `info.getTableName()` 原始值（mirror legacy：CREATE 不解析远端表名）。 + - dropTable override：先 `ExternalDatabase db = getDbNullable(dbName)`；db==null 时按 ifExists 干净返回 / 否则抛（mirror base `:1120-1128`、legacy 经 `getTableNullable`）。再 `ExternalTable dorisTable = db.getTableNullable(tableName)`；dorisTable==null 时按 ifExists 返回 / 否则抛（mirror legacy `dropTableImpl` 的“表不存在”分支与 base `:1124-1128`）。然后用 `dorisTable.getRemoteDbName()` 与 `dorisTable.getRemoteName()` 调 `metadata.getTableHandle(session, remoteDb, remoteTbl)`；后续 `metadata.dropTable(handle)` 不变。editlog 与缓存失效仍用**本地** dbName/tableName（mirror base `:1132` 与 legacy `afterDropTable` 用本地名）。 + - 须 mirror 的 legacy 可观察行为：建/删命中正确远端对象；IF EXISTS 在表不存在时静默成功；非 IF EXISTS 抛明确 `DdlException`；editlog/缓存键沿用本地名（保持 follower replay 一致）。 + - 通用性说明：解析仅依赖 `ExternalCatalog.getDbNullable` + `ExternalDatabase.getRemoteName` + `ExternalTable.getRemoteDbName/getRemoteName`，对所有 PluginDriven 连接器一致；未开名映射时 `getRemoteName()` 回落为本地名（`:408`/`:167` 的 `Strings.isNullOrEmpty` 兜底），行为不变。 + +- **Implementation Plan**（单 issue 独立 commit；仅触 fe-core；编译 `-pl :fe-core -am`）： + 1.

So the 'before' behavior described (OdpsException→RuntimeException) is not what actually happens for a missing DB on the drop path today; the improvement is real (clearer 'database' vs 'table' message) but the stated before-state is inaccurate. +- The design asserts CREATE must NOT remote-resolve the table name and cites legacy as authority. Verified correct (MaxComputeMetadataOps.java:219 passes createTableInfo.getTableName() = local literal; only db uses getRemoteName at :219). No correction to the decision itself — but note legacy createTableImpl ALSO does two FE-side existence checks (tableExist on remote db at :179 and getTableNullable at :189) that the plugin createTable override does NOT replicate and the fix does NOT add. The fix only adds the db null-check, leaving the connector to do the existence/IF-NOT-EXISTS check. This is a pre-existing divergence the fix neither closes nor flags; acceptable for scope but should be stated as an explicit non-goal rather than implied parity. + +**遗漏(gaps)**: +- EXISTING TESTS WILL BREAK, not just 'extend' — the design's test plan says 扩既有 but omits a mandatory rewrite. In /mnt/disk1/yy/.../PluginDrivenExternalCatalogDdlRoutingTest.java the stub TestablePluginCatalog.getDbNullable returns dbNullableResult which DEFAULTS TO null. After the fix, dropTable calls getDbNullable FIRST, so all 4 existing drop tests (testDropTableResolvesHandleRoutesAndUnregisters:176, testDropTableIfExistsWhenMissingIsNoop:190, testDropTableMissingWithoutIfExistsThrows:200, testDropTableWrapsConnectorException:209) will now throw 'Failed to get database' before ever reaching getTableHandle — they currently stub only getTableHandle, never getDbNullable/getTableNullable. Likewise testCreateTableInvalidatesDbCache:223 stubs only getDbForReplay, not getDbNullable, so the new createTable null-check throws DdlException and the test fails. The plan must explicitly list these 5 tests as REQUIRING rewrite (stub dbNullableResult + db.getTableNullable), otherwise the suite goes red. This is a Rule-12 'fail loud' omission. +- SHARED-OVERRIDE BLAST RADIUS understated. CatalogFactory.java:51-52 SPI_READY_TYPES = {jdbc, es, trino-connector, max_compute}. createTable/dropTable in PluginDrivenExternalCatalog are inherited by ALL FOUR, not just max_compute (verified: EsConnectorMetadata/JdbcConnectorMetadata/TrinoConnectorDorisMetadata do NOT override createTable/dropTable). The design repeatedly says '任何 full-adopter' but never names jdbc/es/trino concretely nor adds a UT proving the resolution is benign for a connector whose createTable throws 'not supported'. For DROP on jdbc/es/trino the new getDbNullable+getTableNullable adds a remote getTableNullable round-trip (ExternalDatabase.getTableNullable can hit the remote system, line 270-302) that the current code path skips — behavior end-state is still a throw so no functional regression, but the added remote call on a code path that previously short-circuited is unflagged. +- DROP path adds a getTableNullable() remote round-trip that the CURRENT plugin dropTable does not make (it goes straight to getTableHandle). This matches base ExternalCatalog.dropTable:1123 and legacy, so it is correct parity — but the design's Risk section claims '回归面小' / '逐字节一致' which is false for the unmapped case too: even WITHOUT name mapping, the fix changes the control flow (extra getDbNullable+getTableNullable resolution + potential remote validation, plus changed exception type for missing-db) for every drop on every PluginDriven catalog. The '逐字节一致' claim only holds for the SDK-bound names, not for the FE-side control flow. +- No coverage for the case where FE resolves the table exists locally but getTableHandle(remoteDb,remoteTbl) returns empty (table dropped out-of-band remotely). The existing handle-absent ifExists/throw branch (line 360-365) is preserved, but the test plan adds no case asserting it still fires AFTER the new getTableNullable resolution succeeds — i.e. a table present in FE cache but absent remotely. +- Line numbers and package paths in the design are stale/wrong (it cites fe-core/.../connector/ddl and MaxComputeMetadataOps line refs that don't all line up; actual converter is org.apache.doris.connector.ddl, CREATE override is at PluginDrivenExternalCatalog.java:263-287 with the local-dbName at :268). Cosmetic, but indicates the design was not re-derived against the current tree before writing the plan. + +**额外风险**: +- getDbNullable / getTableNullable on the master can trigger lazy metaCache build / remote round-trips (ExternalDatabase.getTableNullable Step 2-3, lines 270-302) the moment a DDL fires. If the remote (ODPS) is slow/unreachable, CREATE/DROP now blocks on metadata resolution before the SDK call, whereas the current plugin createTable path reaches the converter without that resolution. Minor latency/failure-surface change on the master write path, unmentioned. +- getRemoteDbName() on ExternalTable delegates to db.getRemoteName() (ExternalTable.java:536), and the design resolves db separately via getDbNullable then table via db.getTableNullable. There is a latent assumption that dorisTable.getRemoteDbName() (== its parent db's remoteName) equals the remoteName of the db just fetched via getDbNullable. They should be the same object, but if cache invalidation races between the getDbNullable call and getTableNullable (concurrent refresh), the two could momentarily diverge. Legacy base dropTable has the identical structure so this is not a new risk, but it is unaddressed by any concurrency note. +- The E2E plan proposes lower_case_meta_names=true on a max_compute catalog and asserts post-create visibility. But ODPS project/db naming under name-mapping is environment-specific (mixed-case real DB must already exist on the ODPS side). If the test infra's ODPS project has no mixed-case database, the E2E silently can't exercise the mapping divergence and degenerates to local==remote, giving a green test that does NOT prove the fix (Rule 9 violation). The plan does not specify how the mixed-case remote object is provisioned, so the E2E may not actually fail pre-fix. +- Per Rule 9, the proposed UT 'testCreateTableUsesRemoteDbName' must use a real CreateTableInfoToConnectorRequestConverter (or assert on the dbName actually passed) — but the existing test mocks the converter statically (MockedStatic at line 227). If the new UT keeps mocking the converter, verify(metadata).createTable(argThat(req -> req.getDbName().equals('DB1'))) cannot work because the mocked converter returns a stub req unaffected by the dbName argument. The UT must capture the SECOND argument passed to convert() (the dbName) via the static-mock invocation, not the resulting request's getDbName(). The test-plan wording 'argThat(req -> req.getDbName()...)' is unimplementable against the existing mocking style and would either not compile against intent or pass vacuously. + +--- + +### 阶段 3 — 恢复分区可见 (partitions TVF / SHOW PARTITIONS) + +### FIX-PART-GATES — partitions() TVF + SHOW PARTITIONS analyze 网关 + 分区元数据 override + +**Scope**: review 发现 DDL-C1 / CACHE-C1 / CACHE-C2(severity major,regression=yes,对抗存活 3✓/0✗ ×3),含 ⚠️ Batch-D 红线。本 section 只设计、不写码。 + +#### Problem +翻闸(cutover)后 MaxCompute catalog 变成 `PluginDrivenExternalCatalog`、其表是 `PLUGIN_EXTERNAL_TABLE`。对一张真实分区的 MC 表执行两条用户命令在 FE **analyze 阶段直接抛错**,legacy 可用、翻闸即坏: +- `SELECT * FROM partitions('catalog'='mc','database'='d','table'='t')` → 抛 `AnalysisException("Catalog of type 'max_compute' is not allowed in ShowPartitionsStmt")`(若补了 catalog 网关,下一步又因表类型不在 allow-list 抛 `MetaNotFound`)。 +- `SHOW PARTITIONS FROM ` → 抛 `Table X is not a partitioned table`。 + +触发条件:翻闸后(`SPI_READY_TYPES` 含 max_compute、CatalogFactory 走 PluginDriven)对任意真实分区的 MC 表跑上述两命令。两条命令的 BE 取数支路 / dispatch / handler 都已由 T06c 接好,但因 analyze 网关挡在前面,这些 handler 是**不可达死代码**(`MetadataGenerator.dealPluginDrivenCatalog`、`ShowPartitionsCommand.handleShowPluginDrivenTablePartitions`)。 + +#### Root Cause +三个独立缺口,均为 T06c "FE 分发接线" 漏接 analyze 网关: + +1. **DDL-C1 / CACHE-C1(partitions() TVF 双重网关)** — `fe/fe-core/.../tablefunction/PartitionsTableValuedFunction.java:172-176` 的 catalog allow-list 只认 `internal / HMSExternalCatalog / MaxComputeExternalCatalog`,无 `PluginDrivenExternalCatalog`;`:184-185` 的 `getTableOrMetaException(...)` 允许类型只到 `OLAP/HMS_EXTERNAL_TABLE/MAX_COMPUTE_EXTERNAL_TABLE`,无 `PLUGIN_EXTERNAL_TABLE`。构造器 `:149` 即 eager `analyze()`,故双重挡死。已接好的 BE handler `MetadataGenerator.java:1317-1318`(dispatch)+`:1359-1377`(`dealPluginDrivenCatalog`,走 SPI + remote 名解析)永不可达。 + -

The 'equivalent: !getPartitionColumns().isEmpty()' phrasing for isPartitionedTable() is circular if getPartitionColumns itself depends on the prop. Correct the design to specify the exact prop-sourcing mechanism (re-fetch vs. cache-subclass). +- The Batch-D red-line (part D) is correct AND the existing Batch-D doc is factually wrong as the design states: the amendment at P4-batchD-maxcompute-removal-design.md:70-77 asserts 'P4-T06c adds a PluginDrivenExternalCatalog branch' for PartitionsTableValuedFunction — verified FALSE (the file contains no PluginDrivenExternalCatalog reference at all). The design's instruction to reword 'T06c adds' -> 'FIX-PART-GATES adds' and to gate the :173 MC-branch deletion behind this fix is a valid and necessary correction. No error here; this part is sound. + +**遗漏(gaps)**: +- PROP-SOURCING (load-bearing, unaddressed): The design's getPartitionColumns()/isPartitionedTable() both depend on the connector's `partition_columns` prop, but that prop is NOT persisted anywhere reachable at call time. Verified: PluginDrivenExternalTable.initSchema():108 stores `new SchemaCacheValue(columns)` (base class), and base SchemaCacheValue.java only holds `List schema` (no properties field). There is NO PluginDriven SchemaCacheValue subclass (grep confirms only Iceberg/Paimon/HMS/MaxCompute subclasses exist). ConnectorColumnConverter.convertColumn():67 drops all partition-key markers (it only carries isKey, and MaxComputeConnectorMetadata:141-146 builds partition ConnectorColumns with isKey=false). Therefore the design's stated 'minimal impl: filter getFullSchema() by the prop's name set' is impossible as written — getFullSchema() returns only Columns with no way to identify partition columns, and the prop is not in the cache. The override MUST either (a) re-call metadata.getTableSchema() via the connector SPI on every isPartitionedTable()/getPartitionColumns() call (a remote ODPS metadata round-trip), or (b) introduce a PluginDrivenSchemaCacheValue subclass that persists partition_columns and have initSchema() populate it. The design picks neither and the two design bullets contradict (one says 'read getTableSchema-exposed prop' = re-fetch; the other says 'filter getFullSchema()' = impossible). This must be resolved before implementation. +- PERF/BEHAVIOR DEVIATION not flagged: if the chosen sourcing is per-call getTableSchema() re-fetch (the only option without a new cache subclass), then isPartitionedTable() — called inside ShowPartitionsCommand.validate() at :264 and potentially in planner partition paths — issues a live remote metadata fetch each time, whereas legacy MaxComputeExternalTable.getPartitionColumns():92-97 reads from the cached MaxComputeSchemaCacheValue. Design does not register this as a deviation. +- TEST INFEASIBILITY for the proposed UT not acknowledged: the new 'assert isPartitionedTable()==true' test on PluginDrivenExternalTable requires stubbing the connector's getTableSchema() to return the partition_columns prop AND ensuring the schema-cache/init path is reachable (the existing PluginDrivenExternalTableEngineTest helper never triggers initSchema(); it only exercises getEngine/getEngineTableTypeName which don't touch schema). The test plan doesn't state how the prop is fed to the table under test, which is non-trivial given the prop is not cached. +- COLUMN-NAME MAPPING mismatch for the generalized claim: initSchema():98-105 remaps column names via metadata.fromRemoteColumnName() (e.g., JDBC lowercases), but MaxComputeConnectorMetadata writes the RAW remote partition names into the `partition_columns` prop at :140 BEFORE any mapping. So 'filter getFullSchema() (mapped names) by prop names (raw names)' breaks for any connector that remaps identifiers. MC itself does NOT override fromRemoteColumnName (verified — default returns name unchanged), so MC works today, but the design's central 'keyed on connector, any full-adopter reuses' claim is unsound for remapping connectors and must be either narrowed or fixed by mapping the prop names through fromRemoteColumnName. +- partition_values() TVF gate not mentioned: PartitionValuesTableValuedFunction.java:114-115 has the identical missing-PluginDriven catalog gate and :127 lacks PLUGIN_EXTERNAL_TABLE, and Batch-D's delete list includes its MC branch (~:115). The design scopes out partition_values entirely. This is DEFENSIBLE (verified :132-134 only ever supported HMS tables — 'Currently only support hive table's partition values meta table' — so MC tables always hit that throw even in legacy, meaning no regression and no Batch-D red-line equivalent), but the design should explicitly note it distinguished this case rather than silently omitting a file in the same Batch-D delete list. + +**额外风险**: +- Ordering fragility beyond Batch-D: getPartitionColumns() correctness relies on the prop's comma-separated order matching the schema-append order. Verified this holds today (MaxComputeConnectorMetadata:137-147 builds partitionColumnNames and appends columns in the same loop; legacy MaxComputeExternalTable.initSchema:181-197 appends in odpsTable partition-column order). But if a connector ever builds the prop and the column list in different orders, getPartitionColumns() would silently misorder — there's no invariant enforcing this. Worth a guard/assert or a doc note in the SPI contract for partition_columns. +- isPartitionedTable() is a TableIf default returning false and is consumed in more places than SHOW PARTITIONS (planner, DESCRIBE, partition-prune entry checks). Flipping it to true for MC PluginDriven tables WITHOUT also overriding supportInternalPartitionPruned()/getNameToPartitionItems() (which the design explicitly defers) can produce an inconsistent state: a table that reports isPartitionedTable()==true but supportInternalPartitionPruned()==false and getNameToPartitionItems()=={} (the ExternalTable defaults at :458/:478). Verified ExternalTable.initSchemaAndPartitionPrune-style logic uses these together (PartitionValuesTableValuedFunction/ExternalTable:440-446 gate on supportInternalPartitionPruned + getPartitionColumns + getNameToPartitionItems). The design registers the pruning loss as a known degradation, but should also verify no code path assumes isPartitionedTable()==true IMPLIES non-empty getNameToPartitionItems(), which could NPE/empty-prune-to-full-scan inconsistently rather than cleanly. +- follower/replay and gsonPostProcess: PluginDrivenExternalTable.gsonPostProcess():157-165 only fixes table type; the new overrides read live connector schema, so on a follower FE (or after replay) the first isPartitionedTable() triggers connector init. If the connector/session isn't ready on a follower at validate() time this could throw where legacy (cache-backed) did not. Not analyzed by the design; worth confirming follower behavior for the re-fetch path. +- The new 'non-partitioned guard' in PartitionsTableValuedFunction (design B: `else if (table instanceof PluginDrivenExternalTable && !table.isPartitionedTable())`) will, under per-call re-fetch sourcing, perform a remote getTableSchema() during TVF analyze for every partitions() call on a PluginDriven table — including non-MC connectors that declared no partition_columns (they'll re-fetch, get empty, and throw 'not a partitioned table'). Behavior is correct but adds a remote call to the analyze hot path that legacy MC avoided (legacy used cached getOdpsTable().getPartitions()). + +--- + +### 阶段 4 — 写回正确性 (affected rows) + +### FIX-WRITE-ROWS — INSERT affected rows 恒 0 — doBeforeCommit 补 loadedRows=getUpdateCnt() + +- **Problem**: 翻闸(SPI 事务模型,当前唯一 adopter = MaxCompute)后,对 PluginDriven 外表执行 `INSERT INTO ...` 数据被正确写入,但客户端返回 / `SHOW INSERT RESULT` / `fe.audit.log` 的 returnRows 恒为 `affected rows: 0`。触发条件:catalog 走 SPI 事务模型(`writeOps.usesConnectorTransaction()==true`,即 `connectorTx != null`)的任意 INSERT。JDBC / auto-commit handle 模型(`connectorTx==null`)不受影响。属可观察输出回归(数据不丢,但行数判读错误,影响用户、审计、上层工具)。 + +- **Root Cause**: 精确定位 + - `fe/fe-core/src/main/java/org/apache/doris/nereids/trees/plans/commands/insert/PluginDrivenInsertExecutor.java:146-150` —— `doBeforeCommit()` 只在 `insertHandle != null` 时调 `writeOps.finishInsert(...)`。事务模型下 `insertHandle` 恒为 null(handle 仅在 `beforeExec()` 的 JDBC 分支创建,而事务模型在 `:109-113` 早退),整段被跳过,`loadedRows` 永不赋值。 + - `loadedRows` 字段定义于 `AbstractInsertExecutor.java:69`(`protected long loadedRows = 0;`)。事务模型下,BE 的 MaxCompute sink 只通过 `TMCCommitData.row_count` 上报行数,从不更新 `num_rows_load_success`(DPP_NORMAL_ALL),故 `AbstractInsertExecutor.java:221-222` 取回 0,`loadedRows` 停在默认 0。 + - 下游 `BaseExternalTableInsertExecutor.java:197/201/203` 用 `loadedRows` 设 `setOk` / `setOrUpdateInsertResult` / `updateReturnRows` → 全部为 0。 + - legacy 基线 `MCInsertExecutor.java:74-78`:`doBeforeCommit()` 在 `finishInsert()` 之外还有 load-bearing 的一行 `loadedRows = transaction.getUpdateCnt();`。翻闸 restructure 只镜像了 `finishInsert` 的等价物(`connectorTx.commit` 经 txn manager),漏镜像 `loadedRows` 赋值。 + - 历史误判:`plan-doc/tasks/designs/P4-T05-T06-cutover-design.md:114`(W-c / gap G2)称 `doBeforeCommit ... → null for MC ⇒ correctly skipped`,把"跳过 doBeforeCommit"当作正确——本设计显式推翻该结论(见 Risk)。 + +- **Design**: 在 `PluginDrivenInsertExecutor.doBeforeCommit()` 的事务模型分支回填 `loadedRows`,镜像 legacy 可观察行为。 + - 不扩展任何 SPI:`getUpdateCnt()` 全链路已实现且仅差调用方 —— `ConnectorTransaction.getUpdateCnt()`(default,`fe-connector-api/.../ConnectorTransaction.java:96`)→ `MaxComputeConnectorTransaction.getUpdateCnt()`(`fe-connector-maxcompute/.../MaxComputeConnectorTransaction.java:158-160`,= `sum(TMCCommitData.getRowCount())`)→ 经 `PluginDrivenTransaction.getUpdateCnt()`(`PluginDrivenTransactionManager.java:183-184`)暴露 → `Transaction.getUpdateCnt()`(`Transaction.java:65` default)。`transactionManager.getTransaction(long)` 已声明 `throws UserException`(`TransactionManager.java:30`),与 `doBeforeCommit()` 现有签名 `throws UserException` 兼容。 + - 通用插件层修法,keyed on `connectorTx != null`(SPI 事务模型),非 hardcode maxcompute —— 任何未来事务模型 connector 自动受益;`connectorTx == null` 的 JDBC/auto-commit 路径保持原状(沿用 coordinator/DPP_NORMAL_ALL 取到的 `loadedRows`,与 legacy JdbcInsertExecutor 一致,不回填)。 + - 镜像 legacy 的 mirror 方式:legacy 用 `(MCTransaction) transactionManager.getTransaction(txnId)` 取 txn 再 `getUpdateCnt()`;翻闸已持有 `connectorTx` 字段且 `txnId == connectorTx.getTransactionId()`。两种等价取法:(a) 直接 `connectorTx.getUpdateCnt()`(`connectorTx` 是 executor 现有字段,最少耦合,无需 throws/lookup);(b) `transactionManager.getTransaction(txnId).getUpdateCnt()`(与 legacy 取法逐字一致,但引入 `throws UserException` 的 lookup)。推荐 (a):`connectorTx` 已在手、语义等价、不引入可失败的 manager lookup,改动最小;最终值与 legacy 一致(同一 `TMCCommitData.row_count` 累加链)。 + - 现有 `if (writeOps != null && insertHandle != null)` 的 `finishInsert` 分支不动(JDBC handle 模型仍需);新增逻辑作为事务模型独立分支。 + +- **Implementation Plan**: 逐文件逐方法 + - [fe-core] `fe/fe-core/.../insert/PluginDrivenInsertExecutor.java` `doBeforeCommit()`(:146-150):在现有 `finishInsert` guard 之外,新增事务模型回填分支 —— `if (connectorTx != null) { loadedRows = connectorTx.getUpdateCnt();

Verified the ORDER in legacy MCInsertExecutor.java:75-78 is: getTransaction -> `loadedRows = transaction.getUpdateCnt()` (line 76) THEN `transaction.finishInsert()` (line 77). i.e. legacy reads the count BEFORE finishInsert commits. The fix's recommended approach (a) reads `connectorTx.getUpdateCnt()` in doBeforeCommit BEFORE PluginDrivenTransactionManager.commit() (called later in onComplete:105). Order is preserved — but note getUpdateCnt() reads commitDataList which is independent of commit(), so order is immaterial here; the design's 'order 无关' claim is correct. No behavioral error, just confirming the mirror is faithful. +- The design says approach (b) `transactionManager.getTransaction(txnId).getUpdateCnt()` is 'with legacy 取法逐字一致'. Not quite literal: legacy casts to `(MCTransaction)` and calls the concrete getUpdateCnt; the SPI path returns a `PluginDrivenTransaction` whose getUpdateCnt delegates to connectorTx (PluginDrivenTransactionManager.java:183-184). Semantically equivalent, but (b) is NOT a byte-for-byte mirror. This does not affect the recommendation — (a) is the right choice and the design picks it — but the '逐字一致' characterization of (b) is slightly overstated. + +**遗漏(gaps)**: +- E2E affected-rows capture shape unverified. The design proposes `def res = sql "INSERT ..."; assertEquals(3, res[0][0])`, but no existing external-table write suite (hive/iceberg/mc) uses this pattern — they all verify via `order_qt_*` on a follow-up SELECT. Whether the Doris regression `sql` helper returns INSERT affected-rows as `res[0][0]` (vs. needing `SHOW INSERT RESULT` / a JDBC updateCount path) is unconfirmed in-repo; implementation should pin the exact accessor before claiming the E2E asserts the regression. This is a test-mechanics gap, not a design flaw. +- Multi-statement / multi-fragment accumulation not explicitly covered by the proposed UT. The real value comes from summing N `TMCCommitData.row_count` fed by multiple BE fragment reports; the proposed StubConnectorTransaction returns a single fixed N, so it does not exercise the `commitDataList.stream().sum()` accumulation path (that lives in MaxComputeConnectorTransaction, in fe-connector-maxcompute, which the fe-core UT cannot reach). E2E Test 4 (multi-batch, 3 separate INSERTs of 1 row each) is the only place real accumulation across the feed path is exercised, and the design only proposes asserting Test 1/Test 2 — adding an affected-rows assertion to Test 4 would close this. +- Design does not state whether `filteredRows` should also be backfilled. It correctly mirrors legacy MCInsertExecutor (which only sets loadedRows), and MC never populates DPP_ABNORMAL_ALL so filteredRows legitimately stays 0 — but the design should explicitly note this as an intentional non-change for completeness, since `afterExec`/`setOk` also report a filtered count. +- No mention of the empty-insert path. Verified independently it is safe (empty insert skips executeSingleInsert entirely, so doBeforeCommit never runs and loadedRows=0 is correct), but the design's risk section should have named it since `beginTransaction`/`connectorTx` are skipped there. + +**额外风险**: +- Strict-mode interaction is benign but undocumented. AbstractInsertExecutor.checkStrictModeAndFilterRatio (line 232-246) runs in executeSingleInsert BEFORE onComplete->doBeforeCommit, so it evaluates with loadedRows still 0. For MC this is harmless (filteredRows=0 too, so the ratio guard `filteredRows > ratio*(filteredRows+loadedRows)` is `0 > 0` = false). The backfill happening afterward cannot retroactively affect the strict-mode check — which matches legacy exactly. Worth a one-line note in the design so a future reader doesn't 'fix' the ordering and accidentally make the filter-ratio denominator non-zero. +- getUpdateCnt() is read off connectorTx without holding the synchronized lock that addCommitData/commit use (MaxComputeConnectorTransaction.addCommitData synchronizes on `this`, but getUpdateCnt streams commitDataList unsynchronized). At doBeforeCommit time all BE fragment reports have completed (coordinator.join returned) so no concurrent addCommitData is in flight — same as legacy MCTransaction.getUpdateCnt which is also unsynchronized. Low risk, but it relies on the join->doBeforeCommit happens-before edge; if a future change moves commit-data feed off the join path this read could race. Pre-existing in legacy, not introduced by this fix. +- If a future SPI transaction-model connector returns a stateful ConnectorTransaction but does NOT override getUpdateCnt(), the backfill will silently write 0 (SPI default returns 0) — re-introducing the exact symptom for that connector with no fail-loud. The fix is generic and correct for MC, but the 'any future transaction-model connector automatically benefits' claim is conditional on that connector implementing getUpdateCnt(). Worth flagging in the connector-author contract / SPI javadoc rather than relying on the default. +- The design proposes a doc correction to P4-T05-T06-cutover-design.md:114 and decisions-log but scopes it out of the code commit. Confirmed line 114 does say 'doBeforeCommit ... null for MC => correctly skipped' and is genuinely wrong about loadedRows. Risk: if the doc correction is deferred and forgotten, the stale 'correctly skipped' rationale could mislead a future reviewer into re-removing the backfill during batchD legacy cleanup. Recommend bundling the deviations/decisions-log note into the same change. + +--- + +## 3. 守门 / commit 计划 + +| issue | commit 标题(建议) | 守门(模块) | +|---|---|---| +| FIX-READ-DESC | `[P4-T06d] 读路径 TableDescriptor 类型混淆 — 补 buildTableDescriptor override 产 TMCTable` | mvn ... -pl :fe-connector-maxcompute ... + import-gate | +| FIX-READ-SPLIT | `[P4-T06d] byte_size split size sentinel — 默认 split 回填 size=-1` | mvn ... -pl :fe-connector-maxcompute ... + import-gate | +| FIX-DDL-ENGINE | `[P4-T06d] 无 ENGINE 的 CREATE TABLE — paddingEngineName/checkEngineWithCatalog 识别 PluginDriven` | mvn -f .../fe/pom.xml -pl :fe-core -am ... test-compile + checkstyle:check | +| FIX-DDL-REMOTE | `[P4-T06d] DDL 远端名解析 — CREATE/DROP TABLE 用 getRemoteName/getRemoteDbName 再发 connector` | mvn -f .../fe/pom.xml -pl :fe-core -am ... test-compile + checkstyle:check | +| FIX-PART-GATES | `[P4-T06d] partitions() TVF + SHOW PARTITIONS analyze 网关 + 分区元数据 override` | mvn -f .../fe/pom.xml -pl :fe-core -am ... test-compile + checkstyle:check | +| FIX-WRITE-ROWS | `[P4-T06d] INSERT affected rows 恒 0 — doBeforeCommit 补 loadedRows=getUpdateCnt()` | mvn -f .../fe/pom.xml -pl :fe-core -am ... test-compile + checkstyle:check | + +## 4. 合并 TODO(执行时勾选) + +**阶段 1 — 恢复读路径可用 (gate live SELECT)** +- [ ] FIX-READ-DESC — MaxComputeConnectorMetadata 缺 buildTableDescriptor override,导致翻闸后 toThrift 走 null 兜底产 SCHEMA_TABLE(无 mcTable),BE file_scanner 无条件 static_cast 到 MaxComputeTableDescriptor 类型混淆崩溃;修法为在 MC connector 补 override 产出 MAX_COMPUTE_TABLE+TMCTable,并把 endpoint/quota/properties 透传进 metadata。 + - [ ] test: fe-connector-maxcompute UT: MaxComputeConnectorMetadata.buildTableDescriptor (新增,放 fe-connector-maxcompute/src/test) + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_external_catalog_maxcompute.groovy + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_max_compute_all_type.groovy + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_max_compute_partition_prune.groovy +- [ ] FIX-READ-SPLIT — byte_size split 在翻闸 connector 用 .length(splitByteSize) 回填 rangeDesc.size,丢失 legacy 的 -1 sentinel,使 BE 把 byte-size split 误判为 row-offset → 默认路径静默读出错误数据;改 MaxComputeScanPlanProvider.java:268 为 .length(-1) 恢复 sentinel。 + - [ ] test: fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/MaxComputeScanRangeTest.java (new UT) + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_external_catalog_maxcompute.groovy (default byte_size read path) +**阶段 2 — 恢复 DDL 可用** +- [ ] FIX-DDL-ENGINE — paddingEngineName/checkEngineWithCatalog 在 MC instanceof 分支后新增 PluginDrivenExternalCatalog 分支(keyed on getType()=="max_compute"→ENGINE_MAXCOMPUTE,经 helper 通用化),纯 fe-core 最小改动,镜像 legacy 自动补 engine=maxcompute 行为;须先于 Batch D 删 legacy MC 分支落地。 + - [ ] test: fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/info/CreateTableInfoTest.java (UT: paddingEngineName/checkEngineWithCatalog PluginDriven 分支) + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_max_compute_create_table.groovy (E2E: Test1/Test2/Test3 无 ENGINE 的 CREATE TABLE 翻闸态由 FAIL 转 PASS, qt_test*_show_create_table 断言) +- [ ] FIX-DDL-REMOTE — 在 PluginDrivenExternalCatalog 的 createTable/dropTable override 内先用 getRemoteName/getRemoteDbName 把本地名解析成 ODPS 远端真名再交给连接器，mirror legacy MaxComputeMetadataOps，纯 FE 改动、不扩 SPI、不动连接器。 + - [ ] test: fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java + - [ ] test: regression-test/suites/external_table_p2/maxcompute/test_max_compute_create_table.groovy +**阶段 3 — 恢复分区可见 (partitions TVF / SHOW PARTITIONS)** +- [ ] FIX-PART-GATES — 给 PluginDrivenExternalTable 加 isPartitionedTable/getPartitionColumns override(keyed on connector 的 partition_columns 声明),并在 PartitionsTableValuedFunction.analyze 双网关补 PluginDriven 分支,打通 T06c 已接好的 SHOW PARTITIONS / partitions() TVF BE handler;不删 Batch-D 红线分支。 + - [ ] test: external_table_p2/maxcompute/test_external_catalog_maxcompute + - [ ] test: external_table_p2/maxcompute/test_max_compute_schema + - [ ] test: external_table_p2/maxcompute/test_max_compute_partition_prune +**阶段 4 — 写回正确性 (affected rows)** +- [ ] FIX-WRITE-ROWS — 在 PluginDrivenInsertExecutor.doBeforeCommit() 的事务模型分支(connectorTx != null)补一行 loadedRows = connectorTx.getUpdateCnt(),回填翻闸丢失的 affected-rows,镜像 legacy MCInsertExecutor;getUpdateCnt 全链路已就绪,纯 fe-core 一处赋值。 + - [ ] test: external_table_p2/maxcompute/write/test_mc_write_insert +- [ ] 全部落地后 → 用户跑 live 验证矩阵(SELECT/分区表 SELECT/SHOW PARTITIONS/partitions() TVF/无 ENGINE CREATE TABLE/INSERT affected rows/DROP TABLE/DB) 全绿 → 解锁 Batch D + +## 5. 本批次外(其余存活发现, 待用户定) + +> 以下为 review 存活但**未纳入本批**的 major/minor;

Identical: a key present in both the file and as a user `hive.*` prop resolves to the user value in both. + +# Risk Analysis + +- **Parity vs legacy:** file-resolution reuses the *same* `CatalogConfigFileUtils.loadHiveConfFromHiveConfDir`, so `hadoop_config_dir` base, comma-split, and fail-on-missing-file are identical. Precedence (file as base, user `hive.*` wins) matches `HMSBaseProperties.checkAndInit`. One subtle divergence to call out in tests: legacy keeps the loaded file as a live `HiveConf` and `addResource`s it (lazy, effective values resolved on read), whereas the fe-core hook eagerly flattens to a `Map` of effective values then re-`set`s them. For plain key/value `hive-site.xml` content these are equivalent; the only theoretical difference is XML `` flags or variable-substitution edge cases, which are not connection-critical and not exercised by HMS catalogs in practice. Acceptable and strictly closer to legacy than today's total drop. +- **Shared-code blast radius:** `ConnectorContext.loadHiveConfResources` is a NEW default method returning empty — zero behavior change for every other connector (maxcompute, jdbc siblings, trino) and for the `RecordingConnectorContext` test double (inherits the no-op default unless a test overrides it). `DefaultConnectorContext` gains one method; no existing method touched. The new `buildHmsHiveConf(props)` 1-arg overload delegates, so all existing callers/tests (`PaimonCatalogFactoryTest` 5 HMS tests, `PaimonConnector`) compile and behave unchanged. +- **Edge cases:** (a) `hive.conf.resources` absent/blank → hook gets blank → returns empty map → behaves exactly as today (no regression). (b) Referenced file missing → `CatalogConfigFileUtils` throws `IllegalArgumentException` ("Config resource file does not exist") which propagates out of CREATE CATALOG — fail-loud, matching legacy (today it is silently ignored, which is the very bug). This makes a previously-silent misconfiguration loud; intended per the finding's "at least make the drop loud." (c) Trino/plugin isolated classloaders: not applicable — paimon's `DefaultConnectorContext` runs in fe-core's classloader where `Config`/filesystem are reachable; only the resolved `Map` crosses into the connector, avoiding the `HiveConf`/`Configuration` cross-loader identity hazard noted at `PaimonConnector.java:152-157`. +- **Live-runtime caveat (unchanged by this fix):** the pre-existing B7 note that the live `metastore=hive` Thrift client is host-provided at cutover still stands; this fix only restores the file content into the `HiveConf` and does not alter the classloader story. + +# Test Plan + +## Unit Tests +All in the connector test dir; all PURE/offline (no live metastore). + +**`PaimonCatalogFactoryTest` (new tests; FAIL before fix because the 2-arg overload + base-merge do not exist / file keys are dropped):** + +1. `buildHmsHiveConfOverlaysResolvedHiveConfResourcesAsBase` — call `buildHmsHiveConf(props("uri","thrift://nn:9083"), map("hive.metastore.sasl.qop","auth-conf","hive.metastore.thrift.transport","custom"))`.

No change to `PaimonScanRange` (it already null-guards and empty-guards the map correctly). +4. **Parity behavior** — byte-faithful port of all 8 type cases, `Locale.ROOT` key lowercasing, and the "unsupported type → whole map dropped" rule. + +**Unsupported-type / null-map handling**: Legacy returns `null` for the whole map when any column is unsupported (binary), and the legacy native call site at `PaimonScanNode.java:457` then calls `setPaimonPartitionValues(null)`. The connector's `PaimonScanRange` already treats a null `partitionValues` as `Collections.emptyMap()` (`PaimonScanRange.java:71-73`) and `populateRangeParams` skips empty maps (`:214`), so emitting **no `columnsFromPath`** is the correct parity outcome. To keep the connector's existing non-null contract and avoid NPE risk, I will have `getPartitionInfoMap` **return `Collections.emptyMap()`** (instead of `null`) when any column is unsupported — functionally identical downstream (empty map ⇒ no `columnsFromPath`, same as legacy's null). This is the review's own recommended resolution ("不支持类型返回空 map ... 而非 Object.toString()"). + +**TZ semantics — IMPORTANT, distinct from predicate pushdown**: the connector-session-TZ memory note warns that paimon *predicate pushdown* must NOT use session-TZ (NTZ stays UTC). That caveat is about predicate literal→epoch conversion against stored file stats, and does NOT apply here. Partition-VALUE rendering is a separate concern and legacy explicitly DOES use the session TZ for the LTZ case (`PaimonUtil.java:623` `ZoneId.of(timeZone)` fed from `sessionVariable.getTimeZone()`). So for parity the connector must thread `session.getTimeZone()` into the LTZ case — and ONLY the LTZ case consumes it; all other cases ignore `timeZone`. + +**Bad-alias TZ (CST/PST) handling for the LTZ case**: legacy calls `ZoneId.of(timeZone)` directly with the raw stored Doris string, so legacy itself throws `DateTimeException` for Doris aliases like "CST"/"PST" (`ZoneId.of` rejects them; the connector cannot import the fe-core alias map). I will mirror legacy **exactly**: call `ZoneId.of(timeZone)` with no special degrade. If it throws, the exception propagates out of `planScan` — identical to legacy's behavior (legacy would throw the same `DateTimeException` from `serializePartitionValue`, NOT caught by its `catch (UnsupportedOperationException)`). This is the byte-parity, fail-loud choice consistent with `parseTimestampMillis`'s already-shipped rationale (a wrong zone ⇒ silently wrong partition values ⇒ wrong rows; degrading is unsafe with no BE re-apply for materialized partition values). I will NOT add a friendlier message here (keep the change minimal and behavior identical to legacy); the only realistic path to a bad alias for an LTZ *partition column* is exotic, and parity is the contract. + +# Implementation Plan + +**File: `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonScanPlanProvider.java`** (only file changed) + +1. **Add imports** (alongside existing `org.apache.paimon.*` and `java.*` import groups): + - `import org.apache.paimon.data.Timestamp;` + - `import org.apache.paimon.types.DataType;` + - `import java.time.LocalDate;` + - `import java.time.LocalTime;` + - `import java.time.ZoneId;` + - `import java.time.format.DateTimeFormatter;` + - `import java.util.Locale;` + (`BinaryRow`, `RowType`, `RowDataToObjectArrayConverter`, `LinkedHashMap`, `Collections`, `List`, `Map` already imported.) + +2. **Thread the session TZ at the single call site** in `planScan` (current `:213-215`): + ```java + for (DataSplit dataSplit : dataSplits) { + Map partitionValues = getPartitionInfoMap( + table, dataSplit.partition(), session.getTimeZone()); + ``` + +3. **Replace `getPartitionInfoMap` (`:383-400`)** with the type-aware port: + ```java + private Map getPartitionInfoMap(Table table, BinaryRow partitionValue, String timeZone) { + List partitionKeys = table.partitionKeys(); + if (partitionKeys == null || partitionKeys.isEmpty()) { + return Collections.emptyMap(); + } + RowType partitionType = table.rowType().project(partitionKeys); + RowDataToObjectArrayConverter converter = new RowDataToObjectArrayConverter(partitionType); + Object[] values = converter.convert(partitionValue); + + Map result = new LinkedHashMap<>(); + for (int i = 0; i < partitionKeys.size(); i++) { + try { + String value = serializePartitionValue( + partitionType.getFields().get(i).type(), values[i], timeZone); + result.put(partitionKeys.get(i).toLowerCase(Locale.ROOT), value); + } catch (UnsupportedOperationException e) { + // Legacy parity (PaimonUtil.getPartitionInfoMap): an unsupported partition column + // type (e.g. binary/varbinary) drops the ENTIRE map — BE then materializes no + // columnsFromPath for this split, rather than emitting non-deterministic [B@hash + // garbage.

This matches legacy AND matches the projection path in `planScan` (`:167-169` already lowercases field names). Paimon column names from `rowType().getFieldNames()` are conventionally lowercase already, so for the common case this is a no-op; for mixed-case it now correctly aligns key casing with what BE's `columnsFromPath` matching expects (legacy contract). +- **Shared-code blast radius**: ZERO. `getPartitionInfoMap` is private with a single caller (`planScan`); the new `serializePartitionValue` is a new package-private static with one caller. No SPI signature changes, no fe-core touch, no change to `PaimonScanRange`/handle/metadata. JNI path is unaffected in correctness (BE's JNI reader gets partition info from the serialized split, not `columnsFromPath`; legacy set the map on JNI splits too, so keeping the corrected map on JNI ranges is strictly more-correct and harmless). +- **TZ edge case (CST/PST)**: byte-identical to legacy — `ZoneId.of(rawDorisAlias)` throws `DateTimeException`, propagating out of `planScan`. This is NOT a new regression: legacy threw the same way from the same `ZoneId.of(timeZone)`. It only affects LTZ-typed *partition columns* (rare) under a non-IANA session zone; for all standard zones ("UTC", "Asia/Shanghai", offsets) it is correct. Consistent with the already-shipped fail-loud rationale in `parseTimestampMillis`. +- **TIME case (over-stated finding)**: ported for faithful parity, but practically unreachable — paimon `TIME` maps to UNSUPPORTED in `PaimonTypeMapping` (both directions), so a TIME partition column cannot be created/projected through Doris; legacy's `(Long) value` cast would also throw if it ever ran on the converter's `Integer`. Porting it verbatim (cast to `Long`) keeps byte-parity; if it ever executes it throws `ClassCastException` exactly as legacy would, surfaced loudly rather than silently wrong.

Preferred minimal addition: +- `keyLowercasedAndUnsupportedDropsMap` (only if a real `BinaryRow` for the partition is constructible with the paimon `BinaryRowWriter` available on the test classpath): assert a mixed-case DATE partition key renders lowercase in the result map, and a binary partition column yields `Collections.emptyMap()`. If `BinaryRow` construction proves brittle offline, omit and rely on the static-seam tests (the map wrapper is a trivial 6-line loop fully covered by the seam tests + the single-call-site thread of `session.getTimeZone()`). + +All new tests are offline, no fe-core, no mockito (pure paimon `DataTypes`/`Timestamp` + JUnit5, matching the existing connector test style and classpath — verified `DataTypes.DATE/TIMESTAMP_WITH_LOCAL_TIME_ZONE/FLOAT/DOUBLE/TIME` and `Timestamp.fromLocalDateTime` are on the test classpath). + +## E2E Tests + +Live-only / CI-skipped (no paimon cluster in unit CI; gated like `PaimonLiveConnectivityTest`).

Connector — extract token + emit normalized location keys +File: `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonScanPlanProvider.java` + +Thread `ConnectorContext` into the provider: +- `PaimonConnector.getScanPlanProvider()` (`PaimonConnector.java:91-95`): pass `context` into a new `PaimonScanPlanProvider(properties, catalogOps, context)` ctor (keep existing 2-arg ctor for the offline unit tests that pass no context, or default `context=null`). + +Add a pure static extractor (port of legacy `extractRawVendedCredentials`, paimon-SDK-only): +```java +static Map extractVendedToken(Table table) { + if (table == null) { + return Collections.emptyMap(); + } + FileIO fileIO = table.fileIO(); + if (!(fileIO instanceof RESTTokenFileIO)) { + return Collections.emptyMap(); + } + RESTToken token = ((RESTTokenFileIO) fileIO).validToken(); + Map raw = token == null ? null : token.token(); + return raw == null ?

Add a settable `FileIO fileIO` field (default `null`, with a `setFileIO(...)`), returning it from `fileIO()` so the scan tests can inject a hand-written `RESTTokenFileIO`-shaped double. (See Test Plan for the no-Mockito approach — the module forbids Mockito.) + +Files touched (summary): `ConnectorContext.java` (SPI), `DefaultConnectorContext.java` + `PluginDrivenExternalCatalog.java` (fe-core bridge wiring), `PaimonScanPlanProvider.java` + `PaimonConnector.java` (connector), `FakePaimonTable.java` (test fake), plus the new/extended tests below. + +# Risk Analysis + +- **Parity vs legacy:** The normalization path (`filterCloudStorageProperties` → `StorageProperties.createAll` → `getBackendConfigProperties`) is *identical* to legacy; only the token-extraction site moves into the connector. The gate changes from "metastore is `PaimonRestMetaStoreProperties`" to "table's `fileIO` is `RESTTokenFileIO`" — equivalent for the read path (a REST catalog table yields a `RESTTokenFileIO`; non-REST yields a different `FileIO`), and strictly more precise (won't try to vend on a REST catalog table that happens to have a non-token FileIO). Fail-soft on any extraction/normalization error matches legacy (`AbstractVendedCredentialsProvider` returns null/empty on exception). +- **Shared-code blast radius:** The new `ConnectorContext` method is a `default` no-op, so every other connector (maxcompute, etc.) and every existing `ConnectorContext` implementation (including the test `RecordingConnectorContext`) compiles and behaves unchanged. The `DefaultConnectorContext` ctor gains an overload; the existing 2-arg/3-arg ctors are preserved, and `CatalogFactory.java:106` keeps using the no-vended overload, so non-plugin-driven paths are untouched. The `PluginDrivenExternalCatalog` change only adds a supplier argument. +- **Static-key precedence:** Overlaying vended after static means a catalog that *also* set static `s3.*` keys gets the vended token winning — matches legacy (`getStoragePropertiesMapWithVendedCredentials` replaces base with vended when vended succeeds). Note static `location.s3.*` keys remain raw (un-normalized) and are not consumed by BE's native S3 client — that's the separate sibling P9 finding and out of scope here; this fix does not regress it. +- **Token freshness / expiry:** `validToken()` returns a currently-valid token at plan time (legacy did the same in `doInitialize`). Long-running scans that outlive token TTL are a pre-existing legacy limitation, not introduced here. +- **Edge cases:** empty token map → empty overlay (no-op); non-REST FileIO → empty (no-op); `context == null` (offline unit tests using the 2-arg ctor) → skipped, so the offline harness keeps working; null `validToken()`/`token()` → empty, no NPE. JNI path unchanged (it never used `location.*` creds; BE self-serves from the serialized `RESTTokenFileIO`). +- **No-fe-core-import rule:** The connector only references `org.apache.paimon.rest.{RESTToken,RESTTokenFileIO}` and `org.apache.paimon.fs.FileIO` (paimon SDK) plus the `ConnectorContext` SPI. No `org.apache.doris.datasource.*` import added to the connector. Verified the classes resolve from `paimon-core`/`paimon-common` on the connector classpath. + +# Test Plan + +## Unit Tests +All connector-side tests must use **hand-written fakes, no Mockito** (the module's harness comment and `pom.xml` forbid Mockito). Provide a tiny hand-written `RESTTokenFileIO` double is not possible (it's a concrete class with no no-arg ctor and a final-ish `validToken`), so split tests at the two seams: + +1. `PaimonScanPlanProviderTest.extractVendedToken_*` (new, in connector test dir): + - Because `extractVendedToken` keys on `instanceof RESTTokenFileIO`, drive it with a `FakePaimonTable` whose `fileIO()` returns (a) `null`, (b) a plain hand-written `FileIO` double (not a `RESTTokenFileIO`), and assert an **empty** map — proving non-REST tables vend nothing (INTENT: never leak/attempt vended creds for non-REST). The positive `RESTTokenFileIO.validToken()` branch is covered by the bridge test + E2E (a `RESTTokenFileIO` cannot be hand-constructed offline without a live REST stack). FAILS before if extraction logic were wrong; the current code has no extraction at all, so these tests pin the new contract. + +2. `PaimonScanPlanProviderTest.getScanNodeProperties_overlaysVendedCreds` (new): use a hand-written `ConnectorContext` double whose `vendStorageCredentials(raw)` returns a fixed map `{AWS_ACCESS_KEY=ak, AWS_SECRET_KEY=sk, AWS_TOKEN=tok, AWS_ENDPOINT=ep}` regardless of input, wire it through the 3-arg `PaimonScanPlanProvider` ctor with a `FakePaimonTable`. Assert the returned props contain `location.AWS_ACCESS_KEY=ak` … and that a colliding static key is overridden by the vended value. This FAILS before the fix (no overlay loop, no context param) and PASSES after. INTENT: the connector forwards normalized vended creds to BE under `location.*` with vended-wins precedence. + +3. `PaimonScanPlanProviderTest.getScanNodeProperties_noContext_unchanged` (new): construct with the 2-arg ctor (`context == null`) and assert the property set equals the pre-fix static-only set — guards the offline path and proves no NPE / no behavior change when the hook is absent. + +4. `DefaultConnectorContextVendTest` (new, fe-core test dir — fe-core may use Mockito/real objects): feed a raw OSS token map (`fs.oss.accessKeyId`/`fs.oss.accessKeySecret`/`fs.oss.securityToken`/`fs.oss.endpoint`, mirroring `PaimonVendedCredentialsProviderTest`) into `vendStorageCredentials` and assert the result contains the normalized BE keys `AWS_ACCESS_KEY`/`AWS_SECRET_KEY`/`AWS_TOKEN`/`AWS_ENDPOINT` (and that an empty input yields empty). This pins that the bridge reuses `StorageProperties.createAll` correctly and matches the legacy `PaimonVendedCredentialsProviderTest` + `getBackendPropertiesFromStorageMap` expectations (which already asserts `AWS_*` keys at `PaimonVendedCredentialsProviderTest.java:286-291`). FAILS before (method is a no-op default) and PASSES after. + +5. `RecordingConnectorContext` (connector test fake) needs no change — it inherits the no-op default, confirming the SPI addition is backward compatible. + +## E2E Tests +- A regression case under `regression-test/` analogous to the existing `test_paimon_s3.groovy`, but for a **REST/DLF catalog that vends per-table OSS/S3 credentials with no static `s3.*`/`oss.*` keys**, then `SELECT` a native-readable (ORC/Parquet) table and assert correct rows. This is **live-only / CI-skipped**: it requires a real Paimon REST server (or DLF) that issues vended STS tokens and a private OSS/S3 bucket — there is no offline double for `RESTTokenFileIO.validToken()` (it calls the REST server). Mark it gated behind the existing live-credential regression conf (same gating model as the live `PaimonLiveConnectivityTest`). The unit tests above cover the FE-side wiring deterministically; the E2E validates the end-to-end BE read with a real vended token. + +--- + +# ✅ IMPL SUMMARY (2026-06-11) + +**Status: DONE — connector UT green (PaimonScanPlanProviderTest 15/0); fe-core UT green (DefaultConnectorContextVendTest 2/0); fe-core compiles; imports clean; HEAD uncommitted.** + +## Fix (SPI + fe-core bridge + connector; default-no-op so other connectors unaffected) +- `ConnectorContext.java` (fe-connector-spi): added `default Map vendStorageCredentials(Map raw)` → empty. +- `DefaultConnectorContext.java` (fe-core): override replicates the EXACT legacy `AbstractVendedCredentialsProvider` tail — `CredentialUtils.filterCloudStorageProperties` → `StorageProperties.createAll` → `Collectors.toMap(StorageProperties::getType, identity)` → `CredentialUtils.getBackendPropertiesFromStorageMap`; fail-soft (empty) on any error.

It never ported the **primary** translation. In legacy the primary translation came from `StorageProperties.getHadoopStorageConfig()`, applied separately: + +- **filesystem/hms**: `PaimonHMSMetaStoreProperties.buildHiveConfiguration` (fe-core `PaimonHMSMetaStoreProperties.java:80-84`) iterates `storagePropertiesList` and `conf.addResource(sp.getHadoopStorageConfig())` BEFORE the `appendUserHadoopConfig` overlay. The filesystem/jdbc path feeds the same `getOrderedStoragePropertiesList()` into `CatalogContext` (`PaimonExternalCatalog.createCatalog:147` → `initializeCatalog`). +- **dlf**: `PaimonAliyunDLFMetaStoreProperties.initializeCatalog` (fe-core `PaimonAliyunDLFMetaStoreProperties.java:90-95`) selects the OSS/OSS_HDFS `StorageProperties` and `ossProps.getHadoopStorageConfig().forEach(hiveConf::set)`. + +For S3, `getHadoopStorageConfig` is `AbstractS3CompatibleProperties.appendS3HdfsProperties` (fe-core `AbstractS3CompatibleProperties.java:272-295`): from the canonical `s3.*`/`AWS_*` aliases it sets `fs.s3.impl`, `fs.s3a.impl`, `fs.s3a.endpoint`, `fs.s3a.endpoint.region`, `fs.s3.impl.disable.cache`, `fs.s3a.impl.disable.cache`, `fs.s3a.aws.credentials.provider`, `fs.s3a.access.key`, `fs.s3a.secret.key`, optional `fs.s3a.session.token`, and connection/path-style keys. + +For OSS, it is `OSSProperties.initializeHadoopStorageConfig` (fe-core `OSSProperties.java:315-326`): the S3A block above PLUS `fs.oss.impl` (Jindo), `fs.AbstractFileSystem.oss.impl`, `fs.oss.accessKeyId`, `fs.oss.accessKeySecret`, optional `fs.oss.securityToken`, `fs.oss.endpoint`, `fs.oss.region`. The canonical OSS aliases are declared on `OSSProperties` fields (fe-core `OSSProperties.java:48-91`): endpoint = `{oss.endpoint, s3.endpoint, AWS_ENDPOINT, endpoint, dlf.endpoint, dlf.catalog.endpoint, fs.oss.endpoint}`, accessKey = `{oss.access_key, s3.access_key, ..., dlf.access_key, fs.oss.accessKeyId}`, etc. + +So the connector's allow-list mismatches the keys Doris users actually pass (and the keys its own regression suite passes), and the credentials never reach the Paimon FileIO `Configuration`/`HiveConf`.

The existing two branches (paimon.* re-key, raw fs./dfs./hadoop. passthrough) are **preserved unchanged** for backward compatibility — we only ADD recognition of the canonical aliases the connector currently drops. + +Principles, matching existing style: + +1. **Alias resolution via `firstNonBlank`** over the same alias lists legacy `@ConnectorProperty(names=...)` declared (literal string keys, mirroring how `DLF_*`/`HMS_URI` aliases are already declared as literal arrays in `PaimonConnectorProperties`). No fe-core types. +2. **S3A block** (both flavors): when an access key is resolvable, set `fs.s3a.access.key`/`fs.s3a.secret.key`/`fs.s3a.aws.credentials.provider=...SimpleAWSCredentialsProvider`, optional `fs.s3a.session.token`; always set `fs.s3.impl`/`fs.s3a.impl` + `disable.cache`; set `fs.s3a.endpoint` and `fs.s3a.endpoint.region` when present. This is the verbatim legacy `appendS3HdfsProperties` minus the FE-config-derived connection/timeout defaults (those are not credentials; the existing code already omits them, and Hadoop S3A has its own defaults — keep that minimal-change boundary). +3. **OSS block** (additive): when an OSS access key / endpoint / region is resolvable from canonical `oss.*` aliases, set the Jindo `fs.oss.*` keys (`fs.oss.impl`, `fs.AbstractFileSystem.oss.impl`, `fs.oss.accessKeyId`, `fs.oss.accessKeySecret`, optional `fs.oss.securityToken`, `fs.oss.endpoint`, `fs.oss.region`). Because the canonical OSS endpoint/key aliases overlap with `s3.*` (legacy `OSSProperties` shares them), the S3A block also gets populated from the same values — which is exactly legacy behavior (`OSSProperties.initializeHadoopStorageConfig` calls `super` = the S3A block first). This is desirable: it preserves the legacy "even for OSS we append S3 props for `s3://`-scheme back-compat" comment (fe-core `AbstractS3CompatibleProperties.java:266-269`). +4. **Precedence**: the existing `paimon.*` re-key and raw `fs./dfs./hadoop.` passthrough run AFTER the canonical translation, so an explicitly-passed `fs.s3a.access.key` or `paimon.s3.access-key` still wins (last-write). This matches legacy ordering: `addResource(getHadoopStorageConfig())` (canonical) THEN `appendUserHadoopConfig`/raw (paimon.*) overlay. +5. **Endpoint-from-region derivation is NOT ported** for the filesystem S3 case (legacy `setEndpointIfPossible` lives in `AbstractS3CompatibleProperties` and constructs from URL/region). The regression and documented config always pass an explicit endpoint; deriving it would require porting the S3/OSS endpoint-pattern machinery (large, fe-core-coupled). We set `fs.s3a.endpoint`/`fs.oss.endpoint` only when the user supplied one. For the **DLF** flavor, `buildDlfHiveConf` already derives the DLF *metastore* endpoint from region (`PaimonCatalogFactory.java:466-470`); the OSS *storage* endpoint for DLF should likewise be derivable — see Implementation Plan note (mirror `OSSProperties.getOssEndpoint` only inside the OSS block to keep DLF parity, since DLF users typically pass `dlf.region`/`oss.region` not `oss.endpoint`). + +Helper method `firstNonBlank` already exists and is exactly the alias-priority primitive needed. + +# Implementation Plan + +All changes in `PaimonCatalogFactory.java` (one file; tests in a second).

Because `PaimonConnectorMetadata` inherits the default `ConnectorStatisticsOps.getTableStatistics` (which returns `Optional.empty()`), every paimon plugin table — normal AND system tables (`PluginDrivenSysExternalTable extends PluginDrivenExternalTable`, inherits the same `fetchRowCount`) — reports a base-table row count of -1 (UNKNOWN). + +Legacy `PaimonExternalTable.fetchRowCount()` and `PaimonSysExternalTable.fetchRowCount()` returned the REAL row count (sum of planned-split record counts).

No new fe-core dependency. + +2. **Offline unit-testability via a seam** — this is the load-bearing design decision and the reason I do NOT inline `table.newReadBuilder().newScan().plan().splits()` directly in the metadata method. The whole MVCC/time-travel logic was deliberately structured so `PaimonConnectorMetadata` calls plain-`long`-returning `PaimonCatalogOps` seam methods (see the seam Javadoc at `PaimonCatalogOps.java:79-83`: "return plain `long`s ... so the metadata layer's logic ... is unit-testable offline with `RecordingPaimonCatalogOps`"). The test double `FakePaimonTable.newReadBuilder()` THROWS `UnsupportedOperationException` (`FakePaimonTable.java:237-239`), so a metadata method that called `newReadBuilder()` directly could never be exercised offline. To stay consistent with the module's established pattern AND keep the new logic testable, add a single `long rowCount(Table table)` method to the `PaimonCatalogOps` seam: + + - `CatalogBackedPaimonCatalogOps.rowCount(Table)` does the real paimon work (`newReadBuilder().newScan().plan().splits()` sum), mirroring legacy line-for-line. + - `PaimonConnectorMetadata.getTableStatistics` resolves the table via the existing `resolveTable(handle)` (the same sys-aware resolver every metadata read path uses), calls `catalogOps.rowCount(table)`, applies the legacy `>0 ? n : UNKNOWN` rule, and wraps in `ConnectorTableStatistics(rowCount, -1)` (dataSize left UNKNOWN, matching JDBC reference and the fact legacy never computed a base-table dataSize here). + +`resolveTable` is sys-aware (`PaimonConnectorMetadata.java:931-937` → `PaimonTableResolver.resolve`), so a sys handle resolves its OWN synthetic table and `rowCount` plans the sys table's splits — this single override gives BOTH normal and sys paimon tables their real count, closing Finding 5.1 with the same code (no separate sys path needed, mirroring how legacy had two parallel-but-identical `fetchRowCount` bodies). + +dataSize: returned as -1 (UNKNOWN). Legacy `fetchRowCount` produced only a row count; there is no legacy base-table dataSize to port, and JDBC's reference override also returns dataSize=-1. Keeping dataSize unknown is faithful and avoids inventing a number. + +Error handling: a planning failure (remote IO, etc.) should NOT crash stats collection (which runs in background analysis / SHOW paths). Return `Optional.empty()` (→ FE falls back to -1) on exception, logging a warning — consistent with the connector's other best-effort read paths (e.g. `listDatabaseNames` `PaimonConnectorMetadata.java:96-99`, `collectPartitions` swallowing `TableNotExistException` at :869-873). This preserves the legacy END STATE (-1) on failure without a louder regression than legacy (legacy would have propagated, but legacy ran inside `fetchRowCount` whose callers tolerate exceptions becoming -1; empty-on-failure is the safer, equivalent-visible-result choice and matches the SPI's empty-if-unavailable contract). + +# Implementation Plan + +**File 1 — `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonCatalogOps.java`** + +Add one seam method to the interface (next to the E5 MVCC lookups block, with Javadoc matching the existing seam-rationale style): + +```java +/** + * Returns the total row count of {@code table} = sum of {@code split.rowCount()} over + * {@code table.newReadBuilder().newScan().plan().splits()} (legacy + * PaimonExternalTable.fetchRowCount / PaimonSysExternalTable.fetchRowCount).

Legacy summed `split.rowCount()` over `newReadBuilder().newScan().plan().splits()` and returned `>0 ? n : -1`; the seam impl is identical and the metadata wrapper reproduces the `>0` gate and the 0→UNKNOWN mapping. The only intentional divergence is failure handling (legacy let the exception propagate up `fetchRowCount`; we return empty→-1). The user-visible result is the same fallback (-1) but we avoid surfacing a transient planning error as a query-killing exception during background stats collection — strictly safer, and aligned with the SPI's empty-if-unavailable contract and the module's other best-effort read paths. +- **dataSize**: -1 (UNKNOWN). Legacy never produced a base-table dataSize in `fetchRowCount`, so this is not a regression; any future dataSize work is additive. +- **Shared-code blast radius**: Adding a method to the `PaimonCatalogOps` interface forces every implementor to provide it. There are exactly two: `CatalogBackedPaimonCatalogOps` (production, updated) and `RecordingPaimonCatalogOps` (test, updated). I grepped the module; no other implementor exists. `ConnectorStatisticsOps` / `ConnectorTableStatistics` are untouched, so no other connector (JDBC, MaxCompute) is affected. `fetchRowCount` in fe-core is untouched. +- **Cost-model direction**: Going from a constant -1 to a real positive count CHANGES plans (re-enables join reorder, may flip broadcast/shuffle). This is the intended correction (restoring legacy behavior). It is a planning change, not a correctness change — results stay identical; only plan shape/perf moves toward the legacy baseline. +- **Edge cases**: + - Empty table (0 rows) → `rowCount==0` → empty → -1, matching legacy (which logged and returned -1). + - System tables → resolved via sys-aware `resolveTable`; `rowCount` plans the sys table's own splits. Closes Finding 5.1 with the same code path; no extra sys branch. + - Time-travel / branch handles: `resolveTable` honors the handle's pinned identity (branch/scan options already on the handle), so stats reflect the handle's view. In practice `fetchRowCount` is called on the base table object (analysis path), so the handle is the latest base — but the code is correct for any handle the SPI is asked about. + - Planning cost: each `getTableStatistics` call drives a real `plan()` (one remote scan-plan), same cost as legacy `fetchRowCount`. Called from analysis / SHOW paths, not per-query-hot, so acceptable and unchanged from legacy. + +# Test Plan + +## Unit Tests + +New test class `PaimonConnectorMetadataStatisticsTest` in `fe/fe-connector/fe-connector-paimon/src/test/java/org/apache/doris/connector/paimon/`, driving a `RecordingPaimonCatalogOps` fake (no Mockito, fully offline), mirroring `PaimonConnectorMetadataMvccTest`'s `metadataWith(ops)` pattern.

WHY: a real positive count must reach the FE cost model (not -1) so join-reorder is not force-disabled. Also assert `ops.log` contains `"rowCount"` and `ops.lastRowCountTable == fakeTable`, proving the metadata layer planned the RESOLVED table (not some other handle) — locks the intent that stats are computed from the table the handle denotes. + +2. **`zeroRowCount_mapsToUnknownEmpty`** — `ops.rowCount = 0`; assert result is `Optional.empty()`. WHY: encodes the legacy 0→UNKNOWN(-1) contract; a future change that returned `(0,-1)` instead of empty would corrupt the FE which treats 0 as a real cardinality. This test fails if someone drops the `>0` gate. + +3. **`planningFailure_returnsEmptyNotThrow`** — a `RecordingPaimonCatalogOps` subclass (or a flag) whose `rowCount` throws `RuntimeException`; assert `getTableStatistics` returns `Optional.empty()` and does NOT propagate.

Recommended live regression (paimon p2 external suite, gated on a live paimon env): after `CREATE CATALOG` + `USE` a known paimon table with N committed rows, assert `SELECT COUNT(*)` and the reported stats agree — specifically that `SHOW TABLE STATUS`/`information_schema.tables.table_rows` reports N (not -1) for both a normal table AND a `tbl$snapshots` system table, matching the pre-migration (legacy) baseline. Note in the suite that this is a stats-only assertion (no row-correctness change) and that it must run against the same fixture used for the legacy parity baseline so any drift from legacy `fetchRowCount` is caught.

The map is a byte-for-byte replica of `TimeUtils.java:106-117`. Net effect: every id legacy accepted now resolves identically; ids legacy rejected still fail loud. +- **Blast radius:** Zero shared/fe-core code touched. The new constant is `private static` in one connector class; the only behavioral change is one extra arg to one `ZoneId.of` call reached only from `resolveTimeTravel`'s TIMESTAMP non-digital branch. Digital timestamps (`spec.isDigital()`, :530) never touch `ZoneId.of` and are unaffected (an existing test, `resolveTimestampDigitalUnaffectedByUnsupportedZoneAlias`, locks this). +- **`ZoneId.SHORT_IDS` stability:** It is a JDK-frozen constant (CST/PST/EST mappings are fixed). Legacy uses the same source, so the connector and legacy track each other across JDK versions automatically — no drift risk versus legacy. +- **Edge cases:** + - Offset ids (`+08:00`) and full IANA ids (`Asia/Shanghai`): pass through unchanged (resolved by `ZoneId.of`'s native parsing even with the map present) — verified. + - Case: legacy is case-insensitive; the replica `TreeMap(CASE_INSENSITIVE_ORDER)` matches.

The fe-core bridge `PluginDrivenScanNode.getLocationProperties:307-317` only **strips** the `location.` prefix — it never normalizes. So BE's native ORC/Parquet (FILE_S3) reader receives `s3.access_key` / `oss.access_key` / … , but it parses **only** the canonical `AWS_ACCESS_KEY` / `AWS_SECRET_KEY` / `AWS_ENDPOINT` / `AWS_REGION` / `AWS_TOKEN` (BE `s3_util.cpp:146-150`). + +Result on any **private** object-store bucket (S3 / OSS / COS / OBS): the native reader gets **no usable credentials → 403 / AccessDenied**. Public buckets and the JNI path are unaffected (the serialized paimon `Table` carries its own `FileIO`).

The engine already holds the authoritative parsed map: `DefaultConnectorContext.storagePropertiesSupplier` (= `catalogProperty.getStoragePropertiesMap()`) was wired in fix #1 for `normalizeStorageUri`. The connector replaces its raw passthrough loop with one overlay of this map; the existing `vendStorageCredentials` overlay stays **after** it (vended wins on collision — legacy precedence). This mirrors the `vendStorageCredentials` / `normalizeStorageUri` seams exactly (the task-list's recommended pattern) and is the single source of truth — no re-ported normalization that could drift. + +**Why full replacement (D-048, user-signed), not object-store-only**: `getBackendPropertiesFromStorageMap` is the exact legacy `getLocationProperties()` value. For HDFS catalogs it is **strictly ≥** the current passthrough — `HdfsProperties.getBackendConfigProperties()` preserves every user `hadoop.`/`dfs.`/`fs.`/`juicefs.` override **and** adds the legacy-derived defaults the current loop drops (the review §211 MINOR, folded in for free).

Legacy ships exactly this map → parity. Public buckets get the same `AWS_*` (possibly empty creds + anonymous provider) as legacy. +- **HDFS catalogs**: full replacement is strictly ≥ the old passthrough (preserves user `hadoop.`/`dfs.`/`fs.`/`juicefs.` + adds legacy defaults). Behavioral delta is an *improvement* matching legacy. The only dropped keys are `hive.*`, which legacy never sent to scan location props. +- **Empty storage map** (local-FS warehouse, or non-plugin ctor): returns empty → no overlay. Legacy `getBackendPropertiesFromStorageMap({})` is also empty → parity. BE reads local files without creds. +- **No-context (offline unit tests only)**: the static overlay is skipped (gated, like the vended overlay) → no `location.*` storage props. Production always wires the context (`PaimonConnector:93`), so this only affects unit tests. The old offline behavior (emitting raw `location.s3.*`) was the *bug* — emitting nothing offline is correct. +- **Vended precedence**: vended overlay runs after the static overlay (unchanged), so vended still wins on collision. For REST catalogs the static map may lack keys; the per-table vended overlay supplies them — same two-step structure as today, only the static step is fixed. +- **`AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS` edge (investigated → non-issue)**: unlike legacy (which merges vended INTO the static `StorageProperties` then normalizes ONCE, so keys are present before the provider-type is computed), the connector normalizes static and vended in two steps. So a REST catalog that *also* carries a static object-store endpoint **without** static keys could have the static overlay emit `AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS` (blank-key branch of `AbstractS3CompatibleProperties:124-128`), which the vended overlay (carrying keys → no provider-type) would not clear. **Verified harmless against BE**: both `s3_util.cpp` credential providers (`_get_aws_credentials_provider_v1:383-389`, `_v2:448-455`) check explicit `ak`/`sk` **first** and return `SimpleAWSCredentialsProvider`, never reaching the `Anonymous` branch when keys are present. So the vended keys always win on BE; no regression. (For the primary B-9 case — static catalog WITH keys — the provider-type is null and never emitted.) +- **Other connectors**: identity (empty) SPI default; only paimon calls it. Zero impact on es/jdbc/maxcompute/trino.

A fe-core-bridge-only fix (normalize in `PluginDrivenSplit.buildPath`) is **impossible for the DV path** — the connector bakes it into thrift before fe-core can intercept it. Mixing two mechanisms (bridge for data-file, SPI for DV) would be inconsistent; the SPI hook covers both and keeps format-specific thrift construction in the connector (the established design, `PluginDrivenScanNode.java:761`).

Legacy uses the identical 2-arg `of()`, so parity holds. Verified: the catalog's storage type == the warehouse scheme, so the map always has the entry for a working catalog. +- **Fail-loud**: matches legacy (2-arg `of()` throws `StoragePropertiesException` on missing props). A wrong/un-normalizable path → loud failure instead of silent BE corruption (Rule 12). +- **Vended-vs-static map (scope note)**: legacy overlays vended creds via `VendedCredentialsFactory.getStoragePropertiesMapWithVendedCredentials`; this fix uses the **static** `getStoragePropertiesMap()`. For **scheme** normalization the vended overlay is irrelevant (vended creds change `AWS_*` keys, not the scheme/bucket form) **as long as the warehouse endpoint is statically configured** (the overwhelmingly common case for OSS/COS/OBS — you need the endpoint to connect). The only divergence is a *pure-vended, no-static-storage-config* REST catalog, where `getStoragePropertiesMap()` may lack the entry and normalization throws. That edge overlaps the credential seam fixes (#2 `FIX-STATIC-CREDS-BE` / `FIX-REST-VENDED`) and is **explicitly out of scope** here; tracked in `deviations-log.md`. +- **Other connectors**: SPI method has an identity default; only paimon calls it.

Build a native `DataSplit` (RawFile + DeletionFile with `oss://` paths) through `planScan`; assert the resulting `PaimonScanRange` carries **both** the normalized data-file path (via `getPath()`) **and** the normalized DV path (via `getProperties().get("paimon.deletion_file.path")`).

Only iceberg-core + guava imports; no fe-core. `getPartitionDataJson` swaps fe-core `GsonUtils.GSON` → iceberg's bundled `org.apache.iceberg.util.JsonUtil.mapper().writeValueAsString(List)` (functionally equivalent — BE re-parses the JSON array; byte form is irrelevant). The timezone-bearing methods take a resolved `ZoneId` (from the provider's existing `resolveSessionZone`, alias-map-aware) instead of legacy's raw `String`+`ZoneId.of(tz)` — fixes the latent legacy crash on a non-canonical session `time_zone` (e.g. `"CST"`), consistent with the T02 alias-map fix. +3. **fileFormat = per-file** (`dataFile.format().name().toLowerCase(ROOT)`), paimon-style per-range override in `populateRangeParams`: `"orc"`→`FORMAT_ORC`, `"parquet"`→`FORMAT_PARQUET`, else leave the node default (`FORMAT_JNI`). Node-level `getScanNodeProperties` emits `file_format_type=jni` (paimon parity + forward-compat for P6.5 system-table JNI). *Deviation: legacy is table-uniform; per-file is strictly more correct (legacy has a latent wrong-reader bug on mixed-format tables — rare).* +4. **columns-from-path: unset-then-set, ordered by identity columns.** Provider pre-builds each range's `partitionValues` as a `LinkedHashMap` in `getIdentityPartitionColumns(table)` order, filtered to keys present in the file's `getIdentityPartitionInfoMap` (reproduces legacy's `getOrderedPathPartitionKeys`-ordered, present-filtered columns-from-path). `populateRangeParams` **unsets** the three columns-from-path lists (clear the parent's iceberg-invalid path-parsed values), then, if non-empty, sets keys/values/isNull from the map's entrySet (value `""`/isNull on Java-null). Range overrides `getPartitionValues()` so the parent uses `normalizeColumnsFromPath`; `populateRangeParams` then overwrites it. + - **Adversarial-review fix (Bug 2).** When a partitioned file's identity map is *empty* (partition-spec evolution from a transform to identity, or all-binary/fixed identity columns), `getPartitionValues()` is empty → the generic `PluginDrivenSplit.buildPartitionValues` collapsed empty→`null` → `FileQueryScanNode` fell back to Hive-style **path parsing**, which `throw`s `UserException` for iceberg's non-`key=value` file layout. Legacy never path-parses (it always supplies a non-null empty list). Fix: new `ConnectorScanRange.isPartitionBearing()` (default `false`; `IcebergScanRange` returns `true` when `partitionSpecId != null`) + `buildPartitionValues` returns a non-null empty list for a partition-bearing empty map (non-partition-bearing keep the legacy empty→null collapse → paimon byte-unchanged). +5. **Fail-loud on unsupported file format (Bug 1).** `buildRange` rejects a non-orc/parquet `dataFile.format()` with `"Unsupported format name: %s for iceberg table."`, restoring legacy `getFileFormatType()`'s `DdlException` guard instead of silently leaving the node default `FORMAT_JNI` (which BE would route to its system-table JNI reader). + +## `IcebergScanRange.populateRangeParams` (new override) — mirrors `setIcebergParams` +``` +public void populateRangeParams(TTableFormatFileDesc formatDesc, TFileRangeDesc rangeDesc): + TIcebergFileDesc fileDesc = new TIcebergFileDesc(); + fileDesc.setFormatVersion(formatVersion); + fileDesc.setOriginalFilePath(path); // raw data-file path (== range path; un-normalized) + if (partitionSpecId != null) fileDesc.setPartitionSpecId(partitionSpecId); + if (partitionDataJson != null) fileDesc.setPartitionDataJson(partitionDataJson); + if (formatVersion >= 3) { + fileDesc.setFirstRowId(firstRowId != null ? firstRowId : -1); + fileDesc.setLastUpdatedSequenceNumber(lastUpdatedSequenceNumber != null ? lastUpdatedSequenceNumber : -1); + } + if (formatVersion < 2) fileDesc.setContent(FileContent.DATA.id()); // v1 only (== 0) + // delete_files: T04 + + // native fileFormat (JNI = system tables, P6.5) + if ("orc".equals(fileFormat)) rangeDesc.setFormatType(TFileFormatType.FORMAT_ORC); + else if ("parquet".equals(fileFormat)) rangeDesc.setFormatType(TFileFormatType.FORMAT_PARQUET); + + formatDesc.setTableLevelRowCount(-1); // non-count path (COUNT = T05) + formatDesc.setIcebergParams(fileDesc); // table_format_type already "iceberg" (node) + + // columns-from-path: overwrite the parent's iceberg-invalid path-parsed values + rangeDesc.unsetColumnsFromPath(); + rangeDesc.unsetColumnsFromPathKeys(); + rangeDesc.unsetColumnsFromPathIsNull(); + if (!partitionValues.isEmpty()) { + keys=[], values=[], isNull=[] + for (k,v) in partitionValues: // LinkedHashMap already in identity-column order + keys.add(k); values.add(v != null ? v : ""); isNull.add(v == null) + rangeDesc.setColumnsFromPathKeys(keys); + rangeDesc.setColumnsFromPath(values); + rangeDesc.setColumnsFromPathIsNull(isNull); + } +``` +`getPartitionValues()` overridden → returns `partitionValues`.

The +whole-file `scan.planFiles()` choice is correct and intended (result-identical: under count pushdown BE's +count reader never reads the file, start/length irrelevant, and BE sums `table_level_row_count`); only the +cited reason was wrong. **Fixed** the rationale in `IcebergScanPlanProvider.planCountPushdown` Javadoc and +§1/§2 of this doc — no code-logic change. diff --git a/plan-doc/tasks/designs/P6-T06-iceberg-scan-fieldid-design.md b/plan-doc/tasks/designs/P6-T06-iceberg-scan-fieldid-design.md new file mode 100644 index 00000000000000..1d30c669c77859 --- /dev/null +++ b/plan-doc/tasks/designs/P6-T06-iceberg-scan-fieldid-design.md @@ -0,0 +1,196 @@ +# P6.2-T06 — iceberg field-id schema dictionary (`history_schema_info`) — design + +> **Task**: port the schema-evolution field-id dictionary so BE matches file↔table columns **by field-id** +> (rename/reorder-safe) on iceberg native (parquet/orc) reads, instead of falling back to NAME matching +> (which silently reads NULL/garbage for renamed columns) or DCHECK-aborting the whole BE on a missing +> column (CI #969249 class). **Highest-risk P6.2 task** — UT-invisible (only P6.6 docker e2e truly validates). +> **0 new SPI** (mirrors paimon `FIX-SCHEMA-EVOLUTION` — string property over `getScanNodeProperties` → +> `populateScanLevelParams`; `ConnectorColumn` unchanged).

But `PluginDrivenScanNode.buildColumnHandles` (`:1048`/`:1117`) calls `getColumnHandles( +currentHandle)` BEFORE `pinMvccSnapshot` (`:1059`), so `allHandles` is keyed by CURRENT/latest names. A column +**renamed** `a`→`b` (iceberg field-id 5, permanent) between the pinned snapshot and now: slot `a` → +`allHandles.get("a")` = null → **`a` is dropped from `columns`** → the T06 dict (keyed off `columns`) misses +field-id 5 → BE `iceberg_reader.cpp:181 children_column_exists("a")` **StructNode DCHECK → whole-BE crash**. +(The T06 §6 hypothesis was the FE `buildCurrentSchema` fail-loud; in fact the dropped column never reaches the +dict builder, so the failure is the BE DCHECK, not the FE throw. The design's two fixes — ① build the dict from +the handle's field-id, ② resolve `getColumnHandles` at the pinned handle — both fail: ① the handle is already +dropped upstream, ② `getColumnHandles` has no snapshot param ⇒ a shared fe-core/SPI change that ALSO does not +fix paimon's snapshot-id case.) + +**Option A (chosen, connector-local, 0 SPI / 0 fe-core / 0 paimon impact)**: when the handle carries a snapshot +pin, build the field-id dict from the FULL pinned schema (all columns) instead of the pruned `columns`. Safe and +correct for iceberg because: +1. **BE matches by file field-id, not FE projection.** `by_parquet_field_id` reads each file column's embedded + field-id and matches it to the table-side dict; the dict only needs to be a SUPERSET of the BE scan slots so + the `StructNode` lookup never misses. A full pinned-schema dict is exactly that superset, and the renamed + slot `a` (field-id 5) IS in it → no DCHECK, correct field-id match. +2. **iceberg projection is BE-tuple-driven, not FE-`columns`-driven.** `planScan`/`buildScan` never call + `scan.select(columns)` (verified — `columns` feeds ONLY the dict, line 482). So the upstream-dropped column + does not drop the data read; only the dict needs to be made robust. +3. **Reuses tested code.** Routes time-travel to T06's existing empty-`requestedLowerNames` → all-columns + branch; the dict is small FE→BE metadata, so the lost pruning under time-travel is negligible. Extra dict + entries beyond the slots are harmless (BE only looks up the slots it needs). + +The deeper cross-connector gap — `getColumnHandles` has no snapshot-aware overload, so paimon's snapshot-id +time-travel + rename is the SAME latent BE crash — is **registered as a P6.6 holistic concern** (shared fe-core, +needs paimon impact analysis), like the GLOBAL_ROWID blocker (T06 §6).

+**裁定（用户 2026-06-23 签字）= (B) 挪 T07**，理由： + +1. (B) 唯一的产品调用方是 **T07** 的通用 `RowLevelDmlCommand` 壳（RFC §5.4 原文把 extraction 写在 `RowLevelDmlCommand` 内；数据流图 line 163；task 表 T07 行明列「conflict-filter plumbing」）。在 T05 做 (B) → fe-core 留一段「只有单测、无产品消费者」的悬空抽取件，违反 Rule 2。 +2. (B) 的测试需手工合成 nereids analyzed plan 夹具（连接器测试套件禁 import nereids，测不到）；其测试基建天然属 T07。 +3. **同 T01→T03 先例**：`ConnectorWriteHandle.writeOperation` SPI 载体在 T01 无消费者 → 挪到首消费它的 T03（用户已签字「option B」精神）。 + +**T05 仍定义 SPI 接缝（`ConnectorPredicate` + `applyWriteConstraint`）** —— 接缝先就位、T07 直接调；连接器 override 现期仅 UT 消费（同 T04 整个事务类现期仅 UT 消费，gate-closed 无产品调用方，无回归）。 + +### 2.2 写约束转换惰性化（call-order 决定） + +数据流（RFC line 163-164）：`applyWriteConstraint(...)`（plan 时）→ `beginTransaction`/`planWrite`。即 **`applyWriteConstraint` 在 `beginWrite` 之前调** → 表尚未 load → `IcebergPredicateConverter`（需 `table.schema()`）此刻无法转换。 + +⟹ `applyWriteConstraint` **只暂存中立 `ConnectorPredicate`**；真正转 iceberg `Expression` 推迟到 **commit 时**（`buildWriteConstraintExpression(transaction.table())`，此时 schema 可得）。legacy 的 `conflictDetectionFilter` 字段存的是「已转好的 iceberg `Expression`」（因为 legacy 在 fe-core 命令里就转了）；连接器存中立形、commit 时转——语义等价，且正确处理 call-order。 + +### 2.3 转换丢弃不可转合取项 = 安全（更保守） + +`IcebergPredicateConverter.convert` 会静默丢弃不可转的合取项（scan 侧既有行为）。对 `conflictDetectionFilter` 而言：**丢一个合取项 = filter 变宽 = 冲突检测范围更大 = 更保守**（最坏只是多报冲突 → 多重试，绝不漏报 → 绝不产生错误结果）。与 scan 侧「丢不可下推谓词 = 多扫文件 = 安全」同理。登记 deviation（§6 DV-T05-c）。 + +--- + +## 3.

**分支** `catalog-spi-10-iceberg` @ `dcb86f9e784`。**仅改 fe-core 1 处 + UT**；连接器 0 改（已 ready，§3 实证）。 + +--- + +## 1. recon 推翻 RFC 的两处签字判断（D4/D5） + +起步 recon（独立读码 + 6-agent 对抗 wf `wf_b1bd42e4-675`，526k token）对照真实代码，证伪 RFC WS-PIN 的两块： + +**① 普通表 pin reorder（D4）= 非翻闸阻塞项，且全局改打破 paimon → 用户裁「移出 C1，留 P6.7」。** +- iceberg 普通表时间旅行**现已正确**：连接器 `IcebergScanPlanProvider:705-714`（T06/T07 Option A）在 handle 带 pin 时用**完整 pinned schema** 建 field-id 字典，绕开 latest-schema `columns`，注释明示其补「pin 落 buildColumnHandles 之后」坑。故「BE field-id DCHECK 崩」**非 live 缺口**；reorder 只是把 workaround 的正确性搬进 getColumnHandles 的重构。 +- 全局把 `pinMvccSnapshot` 提到 `buildColumnHandles` 之前会**打破 paimon `@branch` 读**（对抗 verdict=breaks）：paimon `getColumnHandles` 经 `PaimonTableResolver` 对 branch pin 敏感（`withBranch` 清 transient Table → reorder 后解析 branch schema，列名不同被静默丢列）。snapshot-id/tag/timestamp 走 `withScanOptions` 保 base Table、不受影响；jdbc/es/mc/trino 无 MVCC、无影响。**唯 paimon @branch 破**。 +- 另：实有**三**处 pin 点（`getSplits:688/694`、`startSplit:884/892`、`getOrLoadPropertiesResult:1064/1075`），RFC 只点两处，异常通道各异。 + +**② sys-table（D5 Option a「sys implements MvccTable」）机制行不通 → 用户裁「改用 getQueryTableSnapshot 线程」。** +- 真缺口在 sys：`tbl$snapshots FOR TIME AS OF X` 的 pin **从不进连接器 handle**。`PluginDrivenSysExternalTable.resolveConnectorTableHandle:80-81` 取**未 pin** 的 base handle，`getSysTableHandle:398-400` 又仅从 base 继承 pin → sys handle 恒未 pin → 连接器静默读 latest（legacy `IcebergScanNode.createTableScan` 认此时间旅行，翻闸即静默回归）。 +- D5「implements MvccTable」**修不了**：`MvccTableInfo` 按表名 key，pin 存 base 表 key（`tbl`），sys 查 `tbl$snapshots` key，**永不命中**；且 `BindRelation:571-574` 对 sys 表 early-return，`loadSnapshots(sysTable)` **从不被调用**。既不够、方向也偏。 + +--- + +## 2. 机制（rescoped C1）：pinMvccSnapshot 的 sys-fallback + +**唯一改点**：`PluginDrivenScanNode.pinMvccSnapshot()` —— 当 StatementContext 无 snapshot（sys 表恒如此）且 target 是 sys 表且查询带 `FOR TIME AS OF`/`@branch`/`@tag` 时，**直接委派源表 `MvccTable.loadSnapshot(...)`** 解析出 `ConnectorMvccSnapshot`，再经现有 `applyMvccSnapshotPin` 落到 sys handle。 + +```java +private void pinMvccSnapshot() throws UserException { + ConnectorMetadata metadata = connector.getMetadata(connectorSession); + Optional snapshot = MvccUtil.getSnapshotFromContext(getTargetTable()); + if (!snapshot.isPresent()) { + snapshot = resolveSysTableSnapshotPin(); // NEW + } + currentHandle = applyMvccSnapshotPin(metadata, connectorSession, currentHandle, snapshot); +} + +// package-private + 无 SPI 改：复用 source 的 loadSnapshot（TableSnapshot/scanParams→ConnectorTimeTravelSpec +// →resolveTimeTravel→ConnectorMvccSnapshot 的全套转换、not-found 文案、互斥校验都来自 loadSnapshot）， +// 不复制一行解析逻辑。guard checkSysTableScanConstraints 已先行拒掉不支持 pin 的连接器(@incr/paimon)。 +Optional resolveSysTableSnapshotPin() { + if (!(getTargetTable() instanceof PluginDrivenSysExternalTable)) { + return Optional.empty(); + } + if (getQueryTableSnapshot() == null && getScanParams() == null) { + return Optional.empty(); // 普通 sys scan（无时间旅行）= 不 pin + } + PluginDrivenExternalTable source = ((PluginDrivenSysExternalTable) getTargetTable()).getSourceTable(); + if (!(source instanceof MvccTable)) { + return Optional.empty(); // 防御：非 MVCC 连接器（guard 本已拒，双保险） + } + return Optional.of(((MvccTable) source).loadSnapshot( + Optional.ofNullable(getQueryTableSnapshot()), + Optional.ofNullable(getScanParams()))); +} +``` + +**为何零 SPI / 零 MvccTable-on-sys / 零 StatementContext 改**：`loadSnapshot` 解析出的 `ConnectorMvccSnapshot` 是表无关的快照坐标（snapshotId/ref/schemaId）；`applyMvccSnapshotPin:591-600` 解包后 `metadata.applySnapshot(sysHandle, …)` → `IcebergTableHandle.withSnapshot` **保留 sysTableName**（`IcebergTableHandle:141-144`）→ sys handle 带 pin。三处 pin 点都已调用 `pinMvccSnapshot`，故**三处自动覆盖**（修正 RFC「两处」）。 + +**普通表零影响**：context 有 snapshot（普通 MVCC 表路径）→ 走原逻辑，fallback 不触发；`instanceof PluginDrivenSysExternalTable` 把 fallback 严格限定 sys。 + +--- + +## 3. 端到端链路（已实证，§gap 唯一缺口=本设计补的那处） + +1. `tbl$snapshots FOR TIME AS OF X` → `handleMetaTable` 建 sys `LogicalFileScan` **携 tableSnapshot/scanParams**（`BindRelation:467-474`）。✓ +2. translator 经 `FileQueryScanNode` 公共尾 `setQueryTableSnapshot`/`setScanParams`（`PhysicalPlanTranslator:802-805`，对 PluginDrivenScanNode 分支同样生效）。✓ +3. guard `checkSysTableScanConstraints` 放行（iceberg `supportsSystemTableTimeTravel()=true`；@incr 仍拒）。✓ +4. **[GAP] `pinMvccSnapshot` 只读 StatementContext（sys 恒空）→ handle 未 pin** ← **本设计补**。 +5. 连接器 `planScan→planSystemTableScan→buildScan` 在 `handle.hasSnapshotPin()` 时 `useRef`/`useSnapshot`（`IcebergScanPlanProvider:238/305/338-342`）。✓ + +连接器侧（P6.5 T02/T05）已为此 ready：`getSysTableHandle` 保留 pin、`buildScan` 应用

RuntimeException（`PluginDrivenMvccExternalTable:251`）→ 经 pinMvccSnapshot 上抛（与普通表 analysis 期一致，文案已 user-facing）。可接受。 +- 多 pin 点重复调 `loadSnapshot`（getSplits + getOrLoadPropertiesResult 同查询都跑）= 每次重解析（含一次 base schema build，对 sys 浪费但无害）；普通表走 context 缓存无此。**niche 查询，留作后续可选缓存**，不在 C1 优化。 +- @incr 在 guard 即拒，不达 fallback；fallback 的 loadSnapshot 互斥校验（snapshot+scanParams 不可同存）= 双保险。 +- e2e（真 iceberg

一致，是其实现细节）： + +1. **partition_columns 已对**（de-risk RANGE 路径）：`IcebergConnectorMetadata.buildTableSchema:368-377` 已经按 master `loadTableSchemaCacheValue` 走 current spec 取**源列名**（无 identity 过滤、无 dedupe）发 `partition_columns` CSV。fe-core `PluginDrivenExternalTable.getPartitionColumns()` 据此解析 → DAY(ts) 表的分区列就是 `ts`(DATETIME)。故 (3/3) 用 `super.getPartitionColumns()` 拼 RangePartitionItem 的列类型天然正确。 +2. **NULL 分区 = 空 upperBound 信号**（唯一字节忠实方案）：master 对 NULL 值建 `[PartitionKey("0000-01-01"), nullLowKey.successor())`。`successor()` 依赖列的**类型+scale**（DATE→+1 天、DATETIME(scale)→+1 个最小单位），而连接器没有 Doris 列、不该重造 `successor`。故连接器发 `lowerBound=["0000-01-01"]`、**`upperBound=[]`（空）**，由 (3/3) fe-core 用真 `Column` 调 `lowerKey.successor()`。连接器内部 merge 用 `[0000-01-01, +1天]` 的 LocalDateTime 区间（NULL 分区永不 enclose 真分区，merge 值无关）。 +3. **merge 在 LocalDateTime 上做**：master 在 `Range.encloses` 上合并；因都是**对齐时间区间**（年/月/日/时边界），等价于 LocalDateTime 的 `lower<=lower && upper<=upper`。排序复刻 `RangeComparator`（lower 升、upper 降）。逐字移植内层 while（`first` 固定在外层 i、`second` 在内层推进、双 i++）。 +4. **freshness 查表用「全集」非「幸存集」**（移植陷阱）：master `mergeOverlapPartitions` 只从 `nameToPartitionItem`（幸存）删除被 enclose 的，`nameToIcebergPartition`（全集）**从不删**；`getLatestSnapshotId` 在全集里查 merge-set 的 max-lastUpdateTime。故连接器必须保留 `allByName`（全集）+ 单独 `survivors` 集，否则 freshness 查不到被 enclose 分区的 snapshot-id。每分区 `fresh = latest>0 ? latest : tableSnapshotId`（非空表 tableSnapshotId>0，不可达 throw）。 +5. **listPartitionNames（M-10）更通用**：不经资格门——SHOW PARTITIONS 对**任意** partitioned iceberg 表都该出真行（master 整体抛 `not allowed`，翻闸后单列 `listPartitionNames` 默认空=静默 0 行回归）。实现=current spec partitioned 才扫 PARTITIONS（unpartitioned/空表→空 list），返原始 `f1=v1/f2=v2` 名。 +6. **not-exist 降级**：`getMvccPartitionView`/`listPartitionNames` 都在 `context.executeAuthenticated` 内 `catch NoSuchTableException` → 分别 `unpartitioned()` / `emptyList()`（镜像 paimon `collectPartitions` 的 inside-auth catch + fe-core no-handle 降级）。snapshot = `table.currentSnapshot()`（最新；MTMV 分区视图永远读最新，time-travel pin 走 fe-core 空分区臂）。 + +## Implementation Plan（TDD） + +1. **connector-api**：新 `ConnectorMvccPartitionView` + `ConnectorMvccPartition` DTO + `getMvccPartitionView` 默认方法。 +2. **iceberg 连接器**：`IcebergPartitionUtils` 加分区枚举 + range 数学 + 合并 + snapshot-id 解析（移植 master，连接器类型）；`IcebergConnectorMetadata.getMvccPartitionView` + `listPartitionNames`。单测（真 InMemoryCatalog/FakeIcebergTable + PARTITIONS 表 fake）。 +3. **fe-core 通用模型**：`materializeLatest` 加 present 臂；`PluginDrivenMvccSnapshot` 加字段；accessor 改。Mockito 单测（present→RANGE/snapshot-id；absent→旧 LIST/timestamp 不变）。 +4. **mutation**（Rule 9/12）：门、range 边界、合并、snapshot-id 解析、freshness kind 选择、style 选择。 +5. **clean-room 对抗 review**（moderate+ 改动）。 +6. **e2e**：`test_iceberg_mtmv.groovy`（flip-gated，翻闸后才能跑）。 + +## Risk Analysis + +- **paimon 回归**：新方法默认 absent → paimon 走旧路径，**字节不变**（最大风险点，须单测守护旧臂）。 +- **格式化 parity**：RANGE 边界字符串须与 master 同（DATE vs DATETIME 格式）；连接器按 iceberg 源列类型决定，单测对照 master 输出。 +- **合并 fidelity**：`LocalDateTime` enclose 等价 `Range.encloses`（对齐时间区间，无部分相交——master 注释保证）；单测覆盖 DAY-in-MONTH。 +- **snapshot-id `≤0` 回退**：复刻 master

So it +deliberately: +- `buildConflictOr` (`:547`) accepts OR **only when all disjuncts reference the same single column** + → cross-column OR → `null` → guard throws. +- `buildConflictNot` (`:572`) accepts **only `NOT(IS NULL)`** → `NOT(comparison)` → `null` → throws. +- `buildConflictComparison` (`:705`) drops `NE` → `Not(EQ)` reaches `buildConflictNot` → not an IS NULL → throws. + +Master's rewrite converter `IcebergNereidsUtils.convertNereidsToIcebergExpression` (the authoritative matrix) +has **none** of those narrowings: `Or`/`Not` push any convertible child (cross-column OR ✓, NOT(comparison) ✓), +all-or-nothing (throws on any failure). Node set: `And/Or/Not, EQ/GT/GE/LT/LE, In, IsNull, Between`; NE via +`Not(EqualTo)`; **no** same-column / structural / UUID guards. + +**Why not just switch to scan mode?** Two reasons: +- Scan mode's `build()` has **no `ConnectorIsNull` / `ConnectorBetween` case** (the scan-side neutral converter + pre-lowers those to comparisons; the rewrite-side converter emits the nodes directly). So scan mode would + *drop* `IS NULL` / `BETWEEN` — a different regression. +- Scan mode's `buildAnd` (`:176`) **degrades** (drops unbindable arms, keeps the rest) because for scans + widening is safe (BE re-filters). For rewrite that **silently widens** the file set (e.g. + `c=3 OR (a=1 AND int_col='garbage')` → `c=3 OR a=1`, passing the top-level guard) — exactly the R7 violation. + +So the fix is a **dedicated REWRITE mode** mirroring master's matrix: broad (cross-column OR, any-child NOT, NE, +IsNull, Between) **and** strict all-or-nothing everywhere (no silent widen). + +## Design + +Add a third mode to the connector's `IcebergPredicateConverter`. **Engine-neutral, connector-internal: 0 fe-core, +0 SPI, 0 BE, no `instanceof Iceberg`/engine-name (iron rule clean).** + +``` +enum Mode { SCAN, CONFLICT, REWRITE } +``` + +- `SCAN` — unchanged scan pushdown (broad comparison matrix, `buildAnd` degrades, no IsNull/Between nodes). +- `CONFLICT`— unchanged O5-2 write-conflict matrix. +- `REWRITE` — **new**: master's rewrite matrix.

Post-flip the hadoop flavor binds the shared no-op `IcebergNoOpMetaStoreProperties.validate()` (no metastore rules), so a blank/missing `warehouse` degrades from a precise FE `IllegalArgumentException` at CREATE to a delayed, generic Iceberg-SDK error at first use (this is the **L-1** axis). +2. **`warehouse=hdfs://ns/path` → `fs.defaultFS` derivation** — legacy, when the warehouse was an `hdfs://` location, parsed the nameservice and injected `fs.defaultFS = hdfs://` into the catalog properties. The shared HDFS storage detection (`HdfsProperties.guessIsMe`) only recognizes the HDFS backend from `uri`/`fs.defaultFS`/`dfs.nameservices`/`hdfs.config.resources` — **never from `warehouse`**. Without the bridge, a hadoop iceberg catalog configured with only `warehouse=hdfs://ns/path` (relying on FE-side `core-site.xml`/`hdfs-site.xml` on the classpath for the HA nameservice, with no inline `uri`/`fs.defaultFS`/`dfs.*`) no longer binds HDFS storage, and the default FS is no longer pinned to the warehouse nameservice. + +### Impact (narrow → Medium) +Only an **HA-nameservice** hadoop catalog with `warehouse=hdfs://ns/path` and **no** `uri`/`fs.defaultFS`/inline `dfs.nameservices`/`hdfs.config.resources` breaks. A single-NN warehouse with an embedded authority (`hdfs://host:port/path`) still resolves at the SDK level, and any catalog that already supplies HA configs inline (or via `hdfs.config.resources`) is already detected. Workaround today: user adds an explicit `fs.defaultFS`/`uri`. Restoring the legacy auto-derivation removes the surprise. + +## Root cause + +The legacy logic lived in the `IcebergHadoopExternalCatalog` **constructor** (`git show master:fe/fe-core/src/main/java/org/apache/doris/datasource/iceberg/IcebergHadoopExternalCatalog.java`). On the flip path the runtime catalog is the generic `PluginDrivenExternalCatalog`; there is no iceberg constructor hook, and: +- the connector hadoop validate (`IcebergNoOpMetaStoreProperties.validate()`, shared with s3tables) is a no-op → axis 1 lost; +- nothing injects `fs.defaultFS` before storage detection → axis 2 lost. + +### Architecture constraint that pins WHERE axis 2 must be fixed +Storage detection is fe-core and runs **before** the connector is involved in storage: +`CatalogProperty.initStorageProperties()` → `getMetastoreProperties()` (line ~181) → `StorageProperties.createAll(getProperties())` (line ~195). The connector merely **consumes** the storage map fe-core builds (`DefaultConnectorContext` ← `catalogProperty.getStoragePropertiesMap()`). Therefore the `warehouse → fs.defaultFS` bridge **cannot** live in the connector — it must run in fe-core, on the property map fed to `StorageProperties.createAll`, before detection. (Validation axis 1 is free to live at the connector CREATE-time gate, which is where the review points and where the JDBC flavor already does `requireWarehouse()`.) + +## Design + +Mirror the **H-3 pattern** exactly: a neutral hook on `MetastoreProperties` (base = no-op), overridden by the iceberg filesystem flavor. H-3 added `initExecutionAuthenticator(...)` for the same class; this adds a sibling for storage-property derivation. + +### Fix — 4 files + +**(connector, axis 1)** `IcebergNoOpMetaStoreProperties.validate()` — add the warehouse-required check gated on the HADOOP provider only (s3tables, which shares this class, is intentionally untouched — out of M-1 scope). Verbatim legacy message. `isEmpty` (not `isBlank`) is the exact negation of the legacy `Preconditions.checkArgument(StringUtils.isNotEmpty(warehouse), ...)` — a whitespace-only warehouse passes legacy and must pass here too: +```java +if ("HADOOP".equals(providerName) && StringUtils.isEmpty(warehouse)) { + throw new IllegalArgumentException( + "Cannot initialize Iceberg HadoopCatalog because 'warehouse' must not be null or empty"); +} +``` +`warehouse` is the bound field from the connector base `AbstractMetaStoreProperties` (`@ConnectorProperty(names = {"warehouse"})`). Runs at CREATE via `IcebergConnectorProvider.validateProperties` → `bindForType("hadoop").validate()` — guaranteed fail-loud at CREATE regardless of `test_connection`. + +**(fe-core base, neutral SPI)** `MetastoreProperties` — new neutral hook: +```java +public Map getDerivedStorageProperties() { + return Collections.emptyMap(); +} +``` +Storage-config props derived from this metastore's own props that the raw catalog map lacks. Default: none → zero behavior change for every existing catalog type. + +**(fe-core generic, neutral merge)** `CatalogProperty.initStorageProperties()` — feed the derived props into the storage-detection map (reusing the `msp` already fetched on line ~181): +```java +if (checkStorageProperties) { + Map storageProps = getProperties(); + if (msp != null) { + Map derived = msp.getDerivedStorageProperties(); + if (MapUtils.isNotEmpty(derived)) { + storageProps = new HashMap<>(storageProps); + derived.forEach(storageProps::putIfAbsent); // derived = defaults: explicit user keys win + } + } + this.orderedStoragePropertiesList = StorageProperties.createAll(storageProps); + this.storagePropertiesMap = orderedStoragePropertiesList.stream() + .collect(Collectors.toMap(StorageProperties::getType, Function.identity())); +} +``` +Neutral: no engine name / `instanceof` / `if(iceberg)`; the generic code calls a polymorphic hook. For all non-overriding metastores `derived` is empty → identical to today. The merge is into a **copy** — the live persisted `getProperties()` is never mutated. + +**(fe-core iceberg, axis 2)** `IcebergFileSystemMetaStoreProperties.getDerivedStorageProperties()` override — replicate the legacy hdfs-warehouse parse: +```java +@Override +public Map getDerivedStorageProperties() { + if (StringUtils.isBlank(warehouse) || !StringUtils.startsWith(warehouse, HdfsResource.HDFS_PREFIX)) { + return Collections.emptyMap(); + } + String nameService = StringUtils.substringBetween(warehouse, HdfsResource.HDFS_FILE_PREFIX, "/"); + if (StringUtils.isEmpty(nameService)) { + throw new IllegalArgumentException( + "Unrecognized 'warehouse' location format because name service is required."); + } + return Collections.singletonMap(HdfsResource.HADOOP_FS_NAME, HdfsResource.HDFS_FILE_PREFIX + nameService); +} +``` +`HdfsResource`: `HDFS_PREFIX="hdfs:"`, `HDFS_FILE_PREFIX="hdfs://"`, `HADOOP_FS_NAME="fs.defaultFS"`. Same parse and verbatim message as the legacy constructor (`substringBetween(warehouse, "hdfs://", "/")`). This is the existing legacy-exempt iceberg metastore class (the one H-3 modified) — iceberg logic here is a polymorphic override, not a new fe-core `if(iceberg)` seam. + +### Result for `warehouse=hdfs://ns/path` (no uri/fs.defaultFS) +`getDerivedStorageProperties()` → `{fs.defaultFS: hdfs://ns}` → merged copy → `HdfsProperties.guessIsMe` sees `fs.defaultFS` → HDFS detected → `HdfsProperties.initNormalizeAndCheckProps` pins `fsDefaultFS=hdfs://ns` into `backendConfigProperties` (BE) and the storage Hadoop `Configuration` (iceberg SDK FileIO). Storage binding restored on both sinks. + +## Iron rule + +Clean. No new fe-core `if(iceberg)`/`instanceof Iceberg*`/`IcebergUtils` import/engine-name string. The generic `CatalogProperty` merge calls a neutral polymorphic hook; the iceberg derivation lives in the existing `IcebergFileSystemMetaStoreProperties`; the connector gate uses the connector-internal `providerName` discriminator (connector code, not fe-core). `HdfsResource` is an existing fe-core type already referenced across the metastore property package. + +## Known deviations (surfaced — Rule 7/11/12) + +- **Transient vs persisted derivation (LOW, cosmetic).** Legacy `catalogProperty.addProperty(fs.defaultFS, ...)` mutated the **persisted** props; this merges into a transient storage-detection **copy** and re-derives on every init. Functionally equivalent for storage binding, and cleaner (no derived key pollutes persisted props). Cosmetic consequence: `SHOW CREATE CATALOG` will not echo a derived `"fs.defaultFS"` line. Not a correctness axis of M-1. +- **`putIfAbsent` vs legacy overwrite (deliberate, surfaced).** Legacy `addProperty` overwrote any existing `fs.defaultFS`. In the transient-merge model overwrite would desync the storage map from the persisted props, so an explicit user `fs.defaultFS` wins here (`putIfAbsent`). The **M-1 target case (warehouse-only) is identical** under both; the divergence affects only a both-set misconfiguration. +- **empty-nameservice fail-loud timing (LOW).** Malformed `hdfs:///path` (non-blank warehouse, empty nameservice) throws at storage-init (CREATE via `test_connection`, default on; otherwise first use / replay) rather than legacy's constructor time.

The guard is connector-internal (no fe-core reach): it reads the connector's own flavor property and throws the connector-mandated `DorisConnectorException` (NOT fe-core `NotSupportedException`, which the import gate forbids). + +- New helper `isDlfCatalog()` next to `isHmsCatalog()` (`IcebergConnectorMetadata.java:1108`): + `IcebergConnectorProperties.TYPE_DLF.equalsIgnoreCase(catalogType())` (null-safe; `TYPE_DLF = "dlf"`). +- Guard inserted as the **first statement** of each method so it fails before any artifact build or remote call: + - createDatabase → `"iceberg catalog with dlf type not supports 'create database'"` + - dropDatabase → `"iceberg catalog with dlf type not supports 'drop database'"` + - createTable → `"iceberg catalog with dlf type not supports 'create table'"` (the real fail-open fix) + - dropTable → `"iceberg catalog with dlf type not supports 'drop table'"` + - renameTable → `"iceberg catalog with dlf type not supports 'rename table'"` + +Message parity: the first 4 are byte-identical to master's `IcebergDLFExternalCatalog`. `renameTable` is a **consistent extension** — master DLF did not override rename (it fell through to `HiveCompatibleCatalog`'s generic `UnsupportedOperationException`), so there is no master byte to match; the `'rename table'` wording follows the same template for symmetry. (Master's 5th guarded op, `truncateTable`, has **no** connector SPI counterpart, so nothing to guard there.) + +## Implementation Plan +1. `IcebergConnectorMetadata.java`: add `isDlfCatalog()` helper; prepend the 5 guards. +2. UT `IcebergConnectorMetadataDdlTest.java`: add DLF-flavor tests using the existing `metadata(ops, ctx, TYPE_DLF)` fixture — assert each of the 5 throws `DorisConnectorException` with the exact message, the recording seam `ops.log` stays empty (no remote op ran), and auth count is 0 (fails before the auth scope). + +## Risk Analysis +- Guard only fires when `iceberg.catalog.type == "dlf"` (case-insensitive); HMS/REST/Hadoop/Glue/JDBC/S3Tables catalogs are untouched → zero behavior change for the dominant flavors. +- No existing test exercises DLF DDL (recon-verified), so no assertion churn. +- createTable goes from fail-open (live DLF table creation) → fail-loud: strictly safer. +- Iron rule clean: connector-local property read + `DorisConnectorException`; no fe-core import, no engine-name branch in fe-core. + +## Test Plan +### Unit Tests +`IcebergConnectorMetadataDdlTest`: 5 new DLF-flavor cases (one per op) asserting throw + exact message + empty seam log + authCount 0.

GLOBAL_ROWID（被 `MaterializeProbeVisitor.SUPPORT_RELATION_TYPES` 精确类白名单挡，非 classifyColumn），故对 paimon 怎样都安全。③ FE override **不移植进 fe-core**（违「fe-core 不得 `if(iceberg)`」原则）而 **SPI 化**：新 `ConnectorScanPlanProvider.classifyColumn(name)→ConnectorColumnCategory` 默认 DEFAULT、iceberg override 持 ICEBERG_ROWID/row-lineage；`GLOBAL_ROWID` 留 fe-core（Doris 全局机制）。④ **RFC 漏的两处翻闸前置项**：[GAP-A] 翻闸后 iceberg 掉出 `MaterializeProbeVisitor` allowlist→lazy-top-N 失效（→**C5**）；[GAP-B] 隐藏列注入翻闸后缺失（→**随翻闸追踪**）。下列原文仅存档。 + +- **FE**：`PluginDrivenScanNode` 当前**无** `classifyColumn` override → 加之，对 `GLOBAL_ROWID_COL`/`ICEBERG_ROWID_COL` 返 `SYNTHESIZED`、row-lineage 返 `GENERATED`（移植 `IcebergScanNode:907-919`）。D7：connector-guard（仅 iceberg）vs 通用——查证 paimon lazy top-N 触达性。 +- **BE**：`iceberg_reader.cpp:229` 把合成列入 `_id_to_block_column_name`+field_id → `table_schema_change_helper.h:141` `get_children_node` DCHECK 崩。修：合成列走 `add_not_exist_children`（非 `add_children`），不入 field_id map。**不碰 `paimon_reader.cpp`**（iceberg-specific 文件）。 +- 验：FE mutation（去 override → 分类回落 REGULAR）；BE 留 P6.8 docker（合成列 top-N e2e）。 + +### WS-WRITE（C3） +- `visitPhysicalConnectorTableSink:630-681`（通用）补：合成列 `setMaterializedColumnName`（`$operation`/`Column.ICEBERG_ROWID_COL`，移植 `visitPhysicalIcebergMergeSink:613-615`）+ 分布（调 `getRequirePhysicalProperties:142-199` / `toDataPartition:3164-3251` 含 `DistributionSpecMerge:3224-3247`，替 :634 硬编码 UNPARTITIONED）。 +- **connector-guard**：合成列/MERGE 分布仅在

rewrite_data_files **现抛**「Unsupported」（连接器 :89-90，body 未端口）。 +- **judgment D3**：中立 scan-range SPI **不需**——rewrite = FE-plan + per-group 内部 INSERT-SELECT 经通用写路（BE 不见 `FileScanTask`），同 iceberg DELETE/MERGE。连接器内部持 `org.apache.iceberg.FileScanTask`/`RewriteDataGroup`（P6.4 已端口规划半）。 +- **5 seam 泛化**（legacy→通用）： + - SEAM-1/2/5 `(IcebergExternalTable) table`（`IcebergRewriteDataFilesAction:173,196`/`RewriteTableCommand:190`）→ `PluginDrivenExternalTable`（经 connector SPI 重得 iceberg `Table`，模板 `ConnectorExecuteAction:127-130`）。 + - SEAM-3 `(IcebergTransaction)`（`RewriteDataFileExecutor:61`）→ 通用 `ConnectorTransaction`（`IcebergConnectorTransaction` 已实现 SPI；P6.4-T06 有 `WriteOperation.REWRITE` 变体）。 + - SEAM-4 `instanceof PhysicalIcebergTableSink`（`RewriteTableCommand:188`）→ `PhysicalConnectorTableSink`（+ connector/capability 判，模板 `InsertIntoTableCommand:576`）。 +- **端口**：连接器侧补 rewrite executor body（现仅 `RewriteDataFilePlanner`/`RewriteDataGroup`/`RewriteResult` dormant，缺 distributed executor + action body）；连接器 `IcebergExecuteActionFactory` 注册 rewrite_data_files（去 :89 throw）。 +- **C4 中心设计问题（留 WS-REWRITE 子设计）**：per-group rewrite 的 INSERT-SELECT **读端**翻闸后如何精确读目标 file group（legacy 经 `UnboundIcebergTableSink`+特定 FileScanTask；通用路须以 `PluginDrivenScanNode`/connector 读相同 file 子集）——这是 C4 唯一非平凡处，子设计须落实。 +- 验：UT 证 dispatch 到连接器 rewrite + 5 seam 通用化 + ClassCast 消除；mutation；真 commit/compaction 留 P6.8 docker。 + +--- + +## 7. 有序 TODO（每条 = 一个 commit，含 code+test+doc） + +- [ ] **C1

`test_iceberg_position_deletes_sys_table.groovy` 659 行）转绿，解除翻闸 BLOCKER。 + +**非目标**： +- 不动 BE（reader/thrift 已在，本移植只补 FE 产出端）。 +- 不动 fe-core `IcebergScanNode`（HMS-iceberg 残留路径，其系统表两侧都恒抛）。 +- 不重构既有 sys-table JNI 通路（`$snapshots` 等继续走 `serializedSplit`+FORMAT_JNI，逐字节不变）。 +- 不改 `.out` 基线（若必须改 = 说明渲染有偏差，属于**回归**，须先查因，见 D3）。 + +**约束**： +- **fe-connector 不能 import fe-core**（无 `GsonUtils`、无 `Backend`、无 `SessionVariable`）。 +- **fe-core 不得增加任何 iceberg 知识**（架构铁律，HANDOFF 顶部裁定）。 +- BE 契约不可协商（见 §2）。 + +--- + +## 2. 不可协商的外部契约（T0.4 逐字段实证；实现时以本节为准） + +### 2.1 路由（v1 + v2 一致） + +``` +table_format_params 已设 && table_format_type=="iceberg" + && iceberg_params 已设 && iceberg_params.content 已设 && content ∈ {1,3} + && range.format_type ∈ {FORMAT_PARQUET, FORMAT_ORC} +``` +- 顶层 `TIcebergFileDesc.content`（字段 2，**pre-existing 且注释标记 deprecated**）是**唯一判别位**；普通数据 range 从不设它。 +- 🚨 **反向不变量（新增、载荷性）**：**普通数据路径绝不可把顶层 content 设成 1 或 3**，否则劫持正常扫描进此 reader。现状安全（`IcebergScanRange:334` 仅在 formatVersion<2 设 `content=DATA.id()`=0），但从此成为**必须守住的不变量**。 +- 🚨 `range.format_type` **PUFFIN 也必须发 FORMAT_PARQUET**（upstream `getNativePositionDeleteFileFormat`: PARQUET||PUFFIN→FORMAT_PARQUET，ORC→FORMAT_ORC，**AVRO 抛**）。连接器 `populateRangeParams:328-332` 在 fileFormat 既非 orc 也非 parquet 时**默认发 FORMAT_JNI** → 会误路由到 JNI reader。 + +### 2.2 `partition_data_json` —— **不是 JSON 解析！**（最容易踩死的一条） + +BE 把它喂给 **Doris STRUCT 文本 serde**（`data_type_struct_serde.cpp:489-601`），只是**恰好接受 JSON 对象语法**： +- 必须 `{` 开头 `}` 结尾（`:496-507`），否则直接失败。 +- 按 `map_key_delim=':'` / `collection_delim=','` 切分；key `trim_quote()` 后**小写**匹配字段名（`:540-548`）。 +- key 缺失 → `insert_default()` = NULL（`:580-585`）；未知 key 非严格模式**静默丢弃**（`:551-558`）。 +- 🚨 **`DataTypeNullableSerDe::from_string`（`data_type_nullable_serde.cpp:522-534`）吞掉一切解析错误 → 填 NULL 分区 → 返回 `Status::OK()`**。⇒ **形状错了不报错，是静默 NULL/错数据。** +- ⇒ 必须发**类型原生**的扁平对象：`{"p":42,"name":"abc"}`（数字/布尔不带引号，字符串带引号）。 +- ⚠️ 连接器现有 `IcebergPartitionUtils.getPartitionDataJson:204-212` 发的是 **`["42"]` JSON 数组** → 撞 `front()!='{'` → **静默 NULL**。**必须写第二个渲染器**（同一 thrift 字段被两条路以两种形状复用）。 + +### 2.3 `delete_files` —— 恰好 1 个 + +- BE 断言 `size()==1`（`iceberg_position_delete_sys_table_reader.cpp:179`），与数据路径发 N 个不同。 +- **两个 content 都要设且一致**：顶层 `iceberg_params.content`（路由）+ `delete_files[0].content`（reader 种类）。只设一个 → 误路由或 `delete file misses content` 报错。 +- `range.path` 必须**就是 delete 文件本身**（start/size = 其内切片）——reader 把 `_range` 直接交给 ParquetReader/OrcReader。`delete_files[0].path` **也要设**（DV reader 打开的就是它），upstream 设为 `rangeDesc.getPath()`（规范化后），`original_path` = 原始路径（供输出列）。 +- **DV(content=3) 专属**：`content_offset` / `content_size_in_bytes` / `referenced_data_file_path`（thrift 字段 9/10 由 #65135 新增，已在）。 +- PUFFIN vs parquet/orc 的判别**只看 `delete_files[0].content==3`**，不看 file_format（所以 PUFFIN 上那个"假的" FORMAT_PARQUET 永远不会被用到）。 +- **reader 从不读**：`format_version` / `original_file_path` / `first_row_id` / `last_updated_sequence_number` / `serialized_split` / `row_count` / `position_lower_bound` / `position_upper_bound` / `field_ids`。 + +### 2.4 易漏项（upstream 有设、漏了就错） + +- `tableFormatFileDesc.setTableLevelRowCount(-1)`。 +- **`rangeDesc.unsetColumnsFromPath()` + `unsetColumnsFromPathKeys()` + `unsetColumnsFromPathIsNull()`** —— 否则路径解析出的 `partition` key 会与系统表自己的 `partition` 槽**冲突**。 +- `partition_spec_id`。 +- `partition` 列未被投影时可跳过 `partition_data_json`（纯 FE 优化，BE 未设时渲染 NULL）；但**投影了却不发 = 静默 NULL**。 + +--- + +## 3. 架构决策 + +### D1 — smooth-upgrade 守卫：**不移植（用户 2026-07-15 裁定：不考虑兼容问题，按最终形态实现）** + +**⇒ 本移植 fe-core 零改动、SPI 零改动，全部落在 iceberg 连接器内部。**（原方案 a「SPI 中立能力问答 + fe-core 遍历 backendPolicy」与方案 b「仿 Trino NodeManager」**均作废**。） + +**裁定前查清的事实（保留备查，勿再重新发明）**： + +1. **smooth upgrade = 云模式独有的滚动升级**：同机老/新 BE 进程共存。`CloudSystemInfoService:523` 在发现同机要起新进程（`isSmoothUpgradeDst`）时把老 BE 标 `setSmoothUpgradeSrc(true)`；来源是 cloud meta-service（`cloud.proto:252 is_smooth_upgrade`），BE **不经 heartbeat thrift 上报**。设置点全库仅此一处，全在 `cloud/` 包下 ⇒ **非云模式永不为 true**。 +2. **守卫存在的根因在 thrift 设计**：#65135 复用了**已存在且标记 deprecated** 的 `TIcebergFileDesc.content`（字段 2，注释 "deprecated, a data file can have both position and delete files"）当路由判别位。老 BE **不读该字段** → 只看到 `FORMAT_PARQUET`+iceberg → 走**普通数据文件 reader** → 把 position-delete 文件当数据文件解析 → **静默错数据**（非报错）。upstream 因此 fail-fast。 +3. **本质是 FE↔BE 协议版本门，不是 iceberg 关切**。fe-core 已有同构成例：`SplitAggWithoutDistinct:216-225`（老 BE 不认识 `BUCKETED_AGGREGATION_NODE` → 引擎自己遍历 BE → 升级窗口期禁用该功能），**全在 fe-core、零 SPI 参与**。 +4. **Trino 先例在此不适用**（前一版设计框定失准，已纠正）：Trino `NodeManager` 暴露的是 node 拓扑/版本，**没有"同机新旧进程共存"这个概念**；把它塞进中立 SPI 等于让连接器理解 Doris 云上滚动升级。 + +**已知代价（用户已知悉并接受）**：云模式 smooth-upgrade 窗口期查 `$position_deletes` 会命中老 BE → **静默错数据**（非报错）。影响面 = 仅该窗口；本地部署（两个 p0 套件运行环境）不受影响。 +**连带**：upstream FE 单测 6「smooth-upgrade 守卫」**不移植**（其余 5 个照常在连接器侧重表达）。 + +### D2 — range 形状：**`IcebergScanRange` 加第三形状 + 显式判别位**（方案 a） + +`populateRangeParams` 现仅凭 `serializedSplit != null` 二选一。新增： +- 判别位 `positionDeleteSystemTableSplit`（镜像 fe-core `IcebergSplit` 命名）。 +- **新字段，不复用 `originalPath`** —— 该字段现语义 = "原始**数据**文件路径"，被可重写 delete 的 stash（`IcebergScanPlanProvider:626`）消费；position-delete 的 original_path 语义不同，**复用会串味**。 +- 分支次序：`positionDeleteSystemTableSplit` → 原生形状；`serializedSplit != null` → JNI 形状（不变）；否则数据文件形状（不变）。 + +**不新建 `ConnectorScanRange` 实现**：`ConnectorScanRangeType` 保持稳定，且该类已是连接器私有（Rule 3 surgical）。 + +### D3 — 对象 JSON 渲染器：Jackson + **`withExactBigDecimals` 的 mapper 副本**（T0.1 已实证） + +连接器无 gson 依赖；标准化在 `org.apache.iceberg.util.JsonUtil.mapper()`（Jackson）。upstream 用 fe-core 独占的 `GsonUtils.GSON`。 + +**T0.1

**语法变了（科学计数）** | +| `null` | `{}`（**省略 key**） | `{"p":null}` | ⚠️ 字节不同、**语义等价**（BE 两条路都到 NULL） | + +- **根因**（已实证定位）：`mapper.valueToTree()` 走 `JsonNodeFactory`，stock 的 `bigDecimalExact=false` → 去尾零 + 可能转科学计数。**不是 writer 的问题**。 +- **裁定**：用 `JsonUtil.mapper().copy().setNodeFactory(JsonNodeFactory.withExactBigDecimals(true))`，**hoist 成 `private static final`**（`.copy()` 每次分配）。 + - 🚨 **绝不可对 `JsonUtil.mapper()` 单例调 `setNodeFactory`/`configure`** —— 它是 iceberg-core 的**进程级 static**，被所有 iceberg REST/元数据序列化共享，改它会污染无关路径。`.copy()` 已实证不改动共享单例。 + - 备选（同样已实证复现 gson 字节）：`objectNode.put(name, bigDecimal)` 绕过 `valueToTree`。 +- **`null` 的字节差异接受**（记为已知偏差）：BE 对"key 缺失"与"`null` 字面量"都落到 `insert_default()`=NULL（`data_type_struct_serde.cpp:583-586` / `complex_type_deserialize_util.h:79-86`）。**不得为此改 BE**。 + +### D4 — 代码归属 +- 规划分支 → `IcebergScanPlanProvider`（在 `doPlanSystemTableScan` **进入 `buildScan` 之前**分叉）。 +- 分区对象 JSON + 二进制守卫 + 输出字段查找 → `IcebergPartitionUtils`（既有同族，已有 `getPartitionValues`/`serializePartitionValue`）。 + - ⚠️ **必须是新的第二个渲染器**，不可复用 `getPartitionDataJson:204-212`（它发的是 `List` 的 **JSON 数组** `["42"]`，撞 BE 静默 NULL 坑，见 §2）。 +

`IcebergPartitionUtils`**（镜像 `IcebergTypeMapping` 收 boolean 参而非读 map 的既有风格）。**无需改 SPI。** + +### D6 — schema 演进字典：**必须收窄 [D-065]（T0.3，blocker 级）** + +- **实证**：`[D-065]`（`IcebergScanPlanProvider:1037-1052,1090-1109`）对**所有** sys handle 跳过 `iceberg.schema_evolution` 字典，理由是"元数据表 schema 随 serialized FileScanTask 走" —— **该理由只对 JNI 路径成立**。 +- **position_deletes 是第一个走原生（parquet/orc）BE reader 的系统表**，两个 reader 都要 `params.history_schema_info` 解析 `row` 列： + - **v1 硬报错**：`InternalError("Iceberg position delete system table row schema is missing")`（`be/src/format/table/iceberg_position_delete_sys_table_reader.cpp:274-277` parquet / `:325-328` orc）——任何 `SELECT ... row ...` 即炸。 + - **v2 静默退化**：field id 缺失 → `mapping_mode()` 退回 BY_NAME（`format_v2/...:134-155`）→ **schema 演进下重命名列读错且不报错**。 +- **裁定**：把 `:1090` 的 `if (!systemTable)` 门**收窄**为"仅 JNI/serialized-split 系统表跳过"，对 position-delete sys handle **发字典**。 + - 字典须由**元数据表

→ 视图从 `SHOW TABLES` 消失。 +- **根因 B（认不出视图）**：`PluginDrivenExternalTable` 不 override `isView()`，继承 `ExternalTable.isView()==false`（`ExternalTable.java:141-143`）。 + +破坏： +- **(a) 查询视图** = ERROR：根因 A → "table not found"；即便强构造表对象，`IcebergConnectorMetadata.getTableHandle`→`tableExists`（view 为 false）→ `Optional.empty()` → 空 schema（`PluginDrivenExternalTable.java:214-216`）。落 `BindRelation case PLUGIN_EXTERNAL_TABLE:653-658`（与 PAIMON/MAX_COMPUTE/TRINO/LAKESOUL 共享 fall-through）无条件 `LogicalFileScan`。 +- **(b) DROP VIEW / 强制删库** =

pre-flip eager `isView` 一致**。 +3. **视图体 = lazy 方法**（critic 纠正，已实证）：pre-flip `getViewText()`/`getSqlDialect()`（`IcebergExternalTable.java:363-411`）是 lazy（各做一次 remote `loadView`+`currentVersion().summary()`，只在 BindRelation/SHOW CREATE 触发，**不在** `makeSureInitialized`）。故**不**做 eager `view.sql-text` reserved-key（会给每次列表/DESC 加远程读 = 行为变化）。改为 `ConnectorMetadata` lazy 方法 `getViewDefinition(session, handle)` 返回中立 DTO `ConnectorViewDefinition{sql, dialect}`（**一次 round-trip 同时拿 sql+dialect**，pre-flip 是两次 load，本设计可优化为一次）。`PluginDrivenExternalTable.getViewText()`/`getSqlDialect()` 调它。 +4. **drop/list/exists op**（connector-api 当前零 view 方法，已 grep）：`ConnectorMetadata`（或 ConnectorTableOps）新增

+**不会，零损失。** 三段论： + +1. **被排除的只有名字以 `__DORIS_GLOBAL_ROWID_COL__` 开头的列。** `__DORIS_` 是 Doris 引擎保留前缀；该名字由 `LazyMaterializeTopN:178`/`:190` 在 **post-optimizer 阶段合成**，不来自任何外部 catalog 的 schema。 +2. **该列不可能是表列**，故它**永远不可能是 skew 的真阳性载体** —— skew 的定义是"FE tuple 绑定的**表列** schema ≠ 本引用扫描版本的**表列** schema"。合成列在两个版本里都不存在（都由 reader 现造），无从 skew。 +3. **同一 tuple 里的所有真实表列仍被逐个校验。** carve-out 是 per-column 的 `continue`，不是提前 `return`。新增单测 `rowIdColumnIsExcludedNoThrow` 的 `bound = [id@1, rowid@MAX]` 正是为锁死这一点：`id`@1 仍走完整解析。若有人误写成 `return`，`columnAddedAfterScannedVersionThrows`（`bound = [id@1, added@9]`）不会红（它没有 rowid 列）—— 但 `rowIdColumnIsExcludedNoThrow` 本身也不会红。**这是一个已知的测试盲区**，见 R5。 + +**理论残余风险**：若某外部表真有一个列名字面以 `__DORIS_GLOBAL_ROWID_COL__` 开头，该列的 skew 会被漏检。但 (a) 这是 Doris 保留前缀；(b) 更重要的是 —— **既有 `:559` `classifyColumn` 会先把它分类成 `SYNTHESIZED` 而完全不从数据文件读取**，那个 breakage 比漏检 skew 严重得多且先发生。故本改动在这个假想场景下**不新增任何暴露**，与既有两处排除承担完全相同的假设（Rule 11：一致优先）。 + +## R4 — 触发器 2 的耦合 +

恒等于「第一个被绑定的引用的 pin」。C1-a = 恢复该行为（并保留本分支 scan 侧的 version-aware 改进）。 +2. **求值时机不变性（决定性理由）**：因为 `getOutput()` 惰性（`AbstractPlan:91-93`），blind 读可能在只有 1 个 pin 时 + 发生，也可能在有 N 个 pin 时发生。 + - 「第一个」：早求值 → 该表唯一 pin = 第一个；晚求值 → 仍是第一个。**答案与求值时机无关**。 + - 「最后一个」/「任意一个（HashMap 迭代序）」：早晚求值答案不同 ⇒ 引入不确定性。 + 实测反例：`t@tag(t1) JOIN t@tag(t3)`，若取「最后一个」且晚求值，两个 relation 都绑 t3 的 `{c1,c2}`， + t1 那侧的 scan（pinned `{c1}`）就会在 c2 上抛 ⇒ **打挂 `qt_sub_join_tag_with_tag_2`**。 +3. **HashMap 迭代序不可依赖**：现状 `:272` 是 `HashMap`，「任意一个」= 按 hash 桶序，跨 JDK/容量变化不稳定， + 且无法写出能表达意图的单测（Rule 9）。 + +## 为什么这不是「把 fail-loud 换成静默错误」（本设计最重要的论证） +

在**分析期**就要 fail-loud（如 OVERWRITE 落到只支持 INSERT 的连接器、`@branch` 落到不支持 branch 的连接器），早于建 sink。`supportedOperations()` 与 `planWrite` **同在 provider 一个类**：单一来源、不跨模块、契约测试保证两者不漂移（§E）。这是对「早准入」的务实让步，已与用户确认采用。 +

**by-design 保留（P5 后仍在 fe-core，非泄漏）**：`ConnectorContext.executeAuthenticated` doAs 面、存储凭据 NORMALIZATION 到 BE 规范 AWS_*/hadoop 键（`getBackendStorageProperties`/`vendStorageCredentials`，paimon 同赖）、fe-filesystem provider registry。**P5 不得把 normalization 挪进连接器**——边界是"连接器供 raw token/typed StorageProperties，fe-core 归一化"。 + +## 2. 已裁定的子决策（recon 推荐 default，本设计采纳） + +- **[D1] 鉴权器建在哪** = 连接器内 `IcebergConnector.pluginAuthenticator()` bespoke 建（从 `hms.kerberos()` facts），**不新增 SPI 方法**（铁律：无投机 SPI 面；Rule 2/3）。仅 iceberg，paimon 待后续 follow-up 复制同 pattern。 +- **[D2] 删除深度** = 完整删（用户裁定）。两个 storage hook 重新安置到 fe-core 非簇代码：vended gate → 从 raw prop 算（CUT 3）；derived-storage → 独立 helper / 通用化 HDFS warehouse 检测（CUT 4）。 +- **[D3] paimon 残留** = iceberg-only，登记 paimon follow-up（`[FU-paimon-hms-connector-auth]`）；CUT 1 写成可复制 pattern。 +- **[D4] fail-loud vs 静默 no-op** = iceberg 鉴权改**确定性 + kerberos 误配 fail-loud**（Rule 12）；`PluginDrivenExternalCatalog.initPreExecutionAuthenticator:157` 的通用 catch-swallow 仅保留给非 metastore 类型（jdbc/es）。 + +## 3. 刀序（7 刀，每刀独立 commit + build + test + checkstyle 0 + import-gate 净） + +> PREP（1-4，行为保持的增项/重新安置，各自独立可落）→ REWIRE（5，翻掉 plugin 路径对簇的依赖）→ DELETE（6,7）。CUT 5 需 1-4 全落；6/7 需 5。 + +### ✅ CUT 1（DONE `cf8dda9f058`，PREP，novel/最高风险，flip-gated）= 连接器自建 HMS-metastore Kerberos 鉴权器 +- **改**：`IcebergConnector.pluginAuthenticator()`（~738）。现仅 storage-kerberos gate（`properties.get("hadoop.security.authentication")=="kerberos"` → 从 storage conf 建）。**新增**：storage gate 不命中时，若 flavor==hms 且 `hms.kerberos()`（`MetaStoreProviders.bindForType("hms",…)` → `HmsMetaStoreProperties.kerberos()`）present-with-creds → `HadoopAuthenticator.getHadoopAuthenticator(new KerberosAuthenticationConfig(spec.getPrincipal(), spec.getKeytab(), …))`。 +- **等价证明**：`AbstractHmsMetaStoreProperties.kerberos()` javadoc 明写 mirrors `HMSBaseProperties.initHadoopAuthenticator`；fe-core `HMSBaseProperties:176-180` 正是 `new KerberosAuthenticationConfig(clientPrincipal, clientKeytab,…)` → `getHadoopAuthenticator`。连接器 `HadoopAuthenticator`+`KerberosAuthenticationConfig` 均 fe-kerberos（child-first bundled，非 fe-core 依赖）。 +- **precedence**：storage-kerberos（共用 principal 的常见场景）仍走现有 storage-conf 路（不改）；仅补 HMS-kerberos-simple-storage 窄场景。 +- **✅ 落地**：抽包内 static `IcebergConnector.buildPluginAuthenticator(properties, storageHadoopConfig)`；storage-kerberos 分支逐字不变；新增 HMS 分支用 `hms.kerberos()` 的 client principal/keytab 建 `KerberosAuthenticationConfig`（镜像 `HMSBaseProperties.initHadoopAuthenticator:176-180`）。新增 `IcebergConnectorPluginAuthenticatorTest` 5 例。**验收**：fe-connector-iceberg BUILD SUCCESS + checkstyle 0 + 5/5 绿 + mutation 击杀（翻 HMS 分支守卫 → 焦点用例转红）。 +- **⚠️ flip-gated（未跑，登记 ENG-3）**：真正证明须 Kerberized-HMS-on-simple-storage e2e（本地无集群）。注意 CUT 1 使 HMS-kerberos-simple-storage 场景从 fe-core-delegate doAs 立即改走 plugin-UGI doAs（同 principal/keytab，且 plugin-UGI 才是 plugin FileSystem 的正确副本 → 更正确），但该行为变更须 e2e 证明。 + +### ✅ CUT 2（DONE `eb9201dc0a6`，PREP）= SHOW CREATE 脱敏改绑，脱离 IcebergRestProperties +- **落地**：`DatasourcePrintableMap` 删 `getSensitiveKeys(IcebergRestProperties.class)` 反射 + import → 显式 add 4 键（byte-identical，超类链无 sensitive 键）。fe-core 不能引连接器承接类，故显式枚举（非连接器 provider）。 +- **⚠️ 实证纠正（recon 深挖）**：与 `S3Properties` 重叠不均、不可依赖——`iceberg.rest.secret-access-key` 是 S3Properties 敏感 secret-key 别名（冗余），但 `iceberg.rest.session-token` 是 S3Properties `sessionToken`（**非 sensitive**）别名 → 只由本处保护，省略即静默泄漏。故四键全显式。 +- **验收**：fe-core BUILD SUCCESS + checkstyle 0 + `DatasourcePrintableMapTest` 18/18（补断言全 4 键）；mutation 击杀（oauth2.token / session-token 丢 → 转红）；secret-access-key 因 S3 冗余覆盖 mutation 存活（预期）。 + +### CUT 3（PREP，align paimon）= iceberg vended gate 走 raw prop（SDK-free） +- **改**：使 iceberg vended 判定独立于 SDK provider——从 raw `iceberg.rest.vended-credentials-enabled` 算（paimon-style `isVendedCredentialsEnabled` gate，`CatalogProperty:186-192`），使其 `msp==null`（CUT 5 后）仍成立。**暂留** `VendedCredentialsFactory case ICEBERG`（仍返回同 boolean，本刀行为保持）；实删在 CUT 7。 +- **⚠️ 起步先解的设计难点（recon 后新发现，非 CUT 1 阻塞）**：paimon 靠 `msp.isVendedCredentialsEnabled()` 成立**是因为 paimon 保留 msp**；iceberg CUT 5 后 msp==null → 该机制失效 → vended 判定必须能在 msp==null 下工作。但通用 `CatalogProperty.initStorageProperties` 是引擎无关的，直接读 iceberg 专属串 `iceberg.rest.vended-credentials-enabled` 逼近铁律（引擎名判别新 seam）。**候选**：① 该 gate 在 CUT 5 前（msp 尚在）仍走 `msp.isVendedCredentialsEnabled()`，CUT 5 把"iceberg 无 msp 时 vended?"的判定连同鉴权/derived-storage 一起在 `PluginDrivenExternalCatalog`/连接器侧解决（连接器构造前的 init-order 阻塞使连接器供不了 → 需另设中立途径）；② 用中立、非引擎前缀的 vended 标志键。**须在动 CUT 3/CUT 5 前定夺**（届时按 `ask-user-explain-in-chinese-first` 找用户拍板或给出推荐）。 +- **UT**：raw prop true/false/缺省 三态断言 vended gate 结果与今日一致。 + +### ✅ CUT 4（DONE `0de34db83fb`，PREP，纯本地可验）= warehouse→fs.defaultFS 重新安置，脱离待删类 +- **落地**：`CatalogProperty` 新增包内 static `deriveHdfsDefaultFsFromWarehouse(props)`（逐字移植 iceberg 桥，keyed 仅在中立 `warehouse` 键 + hdfs scheme，无引擎名串=守铁律；空 nameservice fail-loud）。`initStorageProperties` 统一 derived 源：`msp!=null` 用 `msp.getDerivedStorageProperties()`（不变），`msp==null` 用中立 helper。 +- **⚠️ 关键：这是 recon 后确定的方案（放弃"通用化 HdfsProperties 对所有 engine 生效"的首选）** —— 通用化会误改非 iceberg catalog（如 paimon fs 只配 hdfs warehouse 时也会 putIfAbsent fs.defaultFS，若与 core-site.xml 的 fs.defaultFS 冲突则回归）。**msp==null 分支** 天然只覆盖 iceberg（post-CUT5）+ jdbc/es/maxcompute/trino（无 hdfs warehouse→no-op），**paimon 有 msp 不受影响**，且行为保持（CUT 4 时 iceberg 仍有 msp 走原路，helper 在 CUT 5 翻掉 iceberg msp 后接替，byte-identical）。 +- **验收**：新增 `CatalogPropertyDeriveHdfsWarehouseTest` 5 例（等价旧 IcebergFileSystemMetaStorePropertiesTest 派生用例）。fe-core BUILD SUCCESS + checkstyle 0 + 5/5 绿 + mutation 击杀 2/2。 +- **⚠️ CUT 3 借鉴受限**：本刀 msp==null 分支的中立 helper 模式**不能直接套用到 CUT 3 vended gate**——warehouse 是中立键，但 vended 判定要读 iceberg 专属键 `iceberg.rest.vended-credentials-enabled`（引擎名串=铁律），CUT 3 仍待用户拍板（见下）。 + +### CUT 5（REWIRE，flip-gated）= plugin 路径停止构造 fe-core iceberg 簇 +- **改**：删 `MetastoreProperties` 对 `Type.ICEBERG` 的 register + `IcebergPropertiesFactory` dispatch → type=iceberg 的 `getMetastoreProperties()` 返回 null（对齐 jdbc/es 既有 null-msp 路径）。CUT 1-4 落地后三活 hook 均有非簇归宿：鉴权器 ← 连接器（CUT 1）、vended gate ← raw prop（CUT 3）、derived-storage ← CUT 4。`initPreExecutionAuthenticator` 对 msp==null 跳过 fe-core 鉴权器（连接器独占）；实现 [D4] fail-loud。 +- **⚠️ 全 flavor e2e**（hms/hadoop/rest/glue/s3tables/dlf/jdbc）——这是翻掉簇的一刀，独立 commit。 + +### CUT 6（DELETE）= 死连通性探测 +- 删 4 个 `Iceberg*ConnectivityTester` + `AbstractIcebergConnectivityTester` + `CatalogConnectivityTestCoordinator:284-303` iceberg 臂 + imports。**前置核验**：iceberg override `checkWhenCreating`→`connector.testConnection`，从不走 base ExternalCatalog 连通性 → 臂死。 + +### CUT 7（DELETE）= fe-core iceberg 属性簇 +- 删

Decisions (from user, 2026-07-01) + +- **D1 — Approach:** create a connector-side **copy** of `CacheSpec` in `fe-connector-api`; fe-core + keeps its own copy. (Not a full move/single-source.) +- **D2 — Scope:** restore validation for **iceberg + paimon** together (add the `-2 → is wrong` + negative to the paimon test too). hudi/jdbc untouched (no `*meta_cache*` test, no surfaced need). + +--- + +## 4. Design + +### 4.1 New shared class + +`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/cache/CacheSpec.java` +— package `org.apache.doris.connector.api.cache`. + +Faithful copy of fe-core `CacheSpec`, with exactly two adaptations required by the module boundary: + +1. **Validators throw `IllegalArgumentException`** instead of `DdlException` (same message text + verbatim: `"The parameter " + key + " is wrong, value is " + value`). This is what the SPI wrapper + catches and re-wraps into `DdlException`, so the user-visible message is identical to legacy. +2. **Drop the `org.apache.commons.lang3.math.NumberUtils` dependency** — `fe-connector-api` has zero + third-party deps (only `fe-thrift` provided). Inline the long parse in `getLongProperty` with a + `try/catch (NumberFormatException) → default` (the connectors' own `propLong` already does this). + +Everything else (immutable value object, `PropertySpec`/`Builder`, the three `fromProperties` +overloads, `isCacheEnabled`, `toExpireAfterAccess`, `metaCacheKeyPrefix`/`isMetaCacheKeyForEngine`, +`applyCompatibilityMap`, constants `CACHE_NO_TTL`/`CACHE_TTL_DISABLE_CACHE`) is JDK-only and copied +unchanged. `fe-connector-api` is excluded from the plugin-zip and loaded once by the app classloader, +so there is no duplicate-class / classloader-split hazard. + +Placement rationale: `fe-connector-api` is the value-object home (siblings `DorisConnectorException`, +`ConnectorPropertyMetadata`), is visible to `fe-connector-spi` and every connector (transitively), and +is already a fe-core dependency. + +### 4.2 Wire validation into the providers (Phase 1 — required) + +Add the legacy checks to each provider's `validateProperties`, **before** the metastore validate, so +invalid cache knobs fail fast (and, for paimon, before the existing dead-knob warning). + +**Iceberg** — `IcebergConnectorProvider.validateProperties` (6 knobs, min values byte-exact to +`IcebergExternalCatalog.java:88-105`): + +| key | check | min | +|---|---|---| +| `meta.cache.iceberg.table.enable` | boolean | — | +| `meta.cache.iceberg.table.ttl-second` | long | `-1` | +| `meta.cache.iceberg.table.capacity` | long | `0` | +| `meta.cache.iceberg.manifest.enable` | boolean | — | +| `meta.cache.iceberg.manifest.ttl-second` | long | `-1` | +| `meta.cache.iceberg.manifest.capacity` | long | `0` | + +**Paimon** — `PaimonConnectorProvider.validateProperties` (3 knobs, byte-exact to deleted +`PaimonExternalCatalog.checkProperties`, recovered from git `0214560d5f3^`): + +| key | check | min | +|---|---|---| +| `meta.cache.paimon.table.enable` | boolean | — | +| `meta.cache.paimon.table.ttl-second` | long | `-1` | +| `meta.cache.paimon.table.capacity` | long | `0` | + +Both validators are `null`-tolerant (absent key → skip), so unset knobs and all currently-valid +catalogs are unaffected. Paimon keeps `warnIgnoredDeadTableCacheKeys` (valid-but-ignored warning) — +validation runs first and only rejects *invalid* values, matching old strictness without losing the +operator-friendly warning. + +Key constants: iceberg already declares them in `IcebergConnectorProperties` (`:62-67`); paimon +declares only `TABLE_CACHE_TTL_SECOND` today — add `TABLE_CACHE_ENABLE` / `TABLE_CACHE_CAPACITY` +constants (or reuse `DEAD_TABLE_CACHE_PREFIX + "enable"/"capacity"`). + +### 4.3 Adopt the shared parse to remove duplication (Phase 2 — recommended, separate commit) + +So the copy is a genuinely *reused* expression (not validator-only) and the hand-rolled duplicates +disappear, refactor the connectors' best-effort parsers onto the shared `CacheSpec`: + +- Iceberg: `IcebergScanPlanProvider.isManifestCacheEnabled`/`propLong` (`:1354-1375`) → + `CacheSpec.isCacheEnabled(...)`; `IcebergConnector.resolveTableCacheTtlSecond` and + `IcebergCatalogFactory` manifest option (`:114-121`) → shared parse. +- Paimon: `PaimonConnector.resolveTableCacheTtlSecond` / `schemaCacheTtlSecondOverride` + (`:125-137,158-172`) → shared parse. + +Behavior-preserving (identical formula), but touches the scan-plan path — guarded by existing +`IcebergScanPlanProviderTest`. **Deferrable**: if we skip Phase 2, trim the copy to the validators + +key helpers to avoid unused methods. + +--- + +## 5. Tests + +- **Iceberg** `test_iceberg_table_meta_cache.groovy` — **unchanged**; its CREATE (`:70-83`) and ALTER + (`:149-152`) `-2 → "is wrong"` assertions are exactly what Phase 1 makes pass. +- **Paimon** `test_paimon_table_meta_cache.groovy` — **add** a CREATE negative + (`meta.cache.paimon.table.ttl-second='-2'` → `exception "is wrong"`) and an ALTER negative + (`alter catalog ... set properties("meta.cache.paimon.table.ttl-second"="-2")` → `exception "is + wrong"`), mirroring iceberg. Keep the existing `ttl-second='0'` positive. +- **Unit (JUnit)** in `fe-connector-api`: port `CacheSpecTest`'s validator cases to the copy, asserting + `IllegalArgumentException` (not `DdlException`) with message containing the key; cover `-1` accepted + (min `-1`), `-2` rejected, non-numeric rejected, non-bool rejected, `null` skipped. +- **Provider unit tests**: extend `PaimonConnectorValidatePropertiesTest` (and add an iceberg + equivalent if none) with the `-2`/garbage cache-knob negatives + valid positives. +- Regression gate: `tools/check-connector-imports.sh` must stay green (new class imports no fe-core). + +--- + +## 6. Ordered TODO + +**Phase 1 — restore validation (required)** +1. Add `fe-connector-api/.../connector/api/cache/CacheSpec.java` (copy; validators → + `IllegalArgumentException`; inline long-parse, no `NumberUtils`). +2. Add `CacheSpecTest` in `fe-connector-api` (validator + parse cases). +3. `IcebergConnectorProvider.validateProperties`: add the 6-knob checks (before metastore validate). +4. `PaimonConnectorProvider.validateProperties`: add the 3-knob checks (before `warnIgnored…`); add the + two paimon key constants. +5. Paimon test: add CREATE + ALTER `-2 → "is wrong"` negatives. +6. Extend provider validate unit tests (paimon; iceberg if applicable). +7. Build fe (`fe-connector-api`, `fe-connector-iceberg`, `fe-connector-paimon`) + run new JUnit + + `check-connector-imports.sh` + checkstyle. Verify iceberg + paimon meta-cache regressions locally. + +**Phase 2 — remove duplication (recommended, separate commit)** +8. Refactor iceberg scan-path + factory parse onto shared `CacheSpec`; keep `IcebergScanPlanProviderTest` green. +9. Refactor paimon parse onto shared `CacheSpec`. + +**Wrap-up** +10. Update `plan-doc/HANDOFF.md`; commit per phase. + +--- + +## 7. Risks / alternatives + +- **Exception type.** If a validator threw `DorisConnectorException` it would escape the + `catch (IllegalArgumentException)` bridge and NOT surface as `is wrong`. Mitigation: throw + `IllegalArgumentException` (matches existing metastore validators). Covered by unit + regression. +- **Duplication (fe-core vs connector copy).** Two `CacheSpec` classes can drift. Accepted per D1; the + logic (message + min-compare) is tiny/stable. Full single-source move remains a future option. +- **Paimon behavior change.** Restoring paimon validation reintroduces a check intentionally removed at + cutover; accepted per D2. Only *invalid* values are rejected — valid catalogs unaffected; the + dead-knob warning is preserved. +- **Phase 2 scan-path touch.** Behavior-preserving but in a hot path; isolated to a separate commit and + gated by existing tests. Skippable (trim copy) if undesired. +- **Min-value divergence with hive** (iceberg/paimon accept `-1`, hive rejects it). Deliberately not + unified; `minValue` stays a caller argument so each connector keeps its legacy rule. + +--- + +## 8. Implementation outcome (2026-07-01) + +**Phase 1 (validation restored)** — new `fe-connector-api/.../connector/api/cache/CacheSpec.java` +(faithful copy; validators throw `IllegalArgumentException`; long-parse inlined) + `CacheSpecTest`. +`IcebergConnectorProvider.validateProperties` now checks the 6 iceberg knobs and +`PaimonConnectorProvider.validateProperties` the 3 paimon knobs (before its dead-knob warning). Added +paimon `TABLE_CACHE_ENABLE`/`TABLE_CACHE_CAPACITY` constants. Paimon regression got CREATE+ALTER +`-2 → "is wrong"` negatives. + +**Phase 2 (dedup)** — `IcebergScanPlanProvider.isManifestCacheEnabled` and +`IcebergCatalogFactory.appendManifestCacheProperties` now parse via the shared `CacheSpec.fromProperties` ++ `CacheSpec.isCacheEnabled`, deleting the hand-rolled `propLong` / `getBoolean` / `getLong` (and the now +unused `NumberUtils` import). This restores legacy no-trim semantics (fe-core `CacheSpec` never trimmed; +the connector's `propLong` had added trimming) — a behavior change only for whitespace-padded numeric +values, which no test/regression uses. + +**Scoping deviation (surfaced):** the ttl-only best-effort parsers — `IcebergConnector` +`resolveTableCacheTtlSecond` and `PaimonConnector` `resolveTableCacheTtlSecond` / +`schemaCacheTtlSecondOverride` — were **left as-is**. They are not `isCacheEnabled` re-implementations, and +each carries an operator `LOG.warn` on a bad value that `CacheSpec` does not; routing them through +`CacheSpec.fromProperties` would drop the warning and over-read enable/capacity. Deduping them would be a +regression, so they stay. + +**Test-intent conflict resolved (Rule 7):** the pre-existing paimon unit test +`deadTableCacheKeyIsAcceptedNotRejected` asserted `meta.cache.paimon.table.capacity=-5` is *accepted* +(warn-only) — the exact post-cutover behavior this task reverses. Replaced with `rejectsMalformedMetaCacheKnob` ++ `acceptsValidMetaCacheKnobs` per the restore directive. + +**Verification:** `fe-connector-{api,iceberg,paimon}` reactor build (`-am`, `-Drevision=1.2-SNAPSHOT`) +BUILD SUCCESS; checkstyle clean; full suites green — CacheSpecTest 9/9, +IcebergConnectorValidatePropertiesTest 11/11, PaimonConnectorValidatePropertiesTest 15/15, whole iceberg +module 892/0-fail (1 pre-existing skip). Regression-suite audit: no other suite feeds an invalid +`meta.cache.*` value that the restored validation would newly reject. **Not run** (no cluster): the +docker regressions `test_iceberg_table_meta_cache` / `test_paimon_table_meta_cache` — same code path is +covered by the provider unit tests. + +**Commit/staging caveat:** `IcebergScanPlanProvider.java` carried pre-existing uncommitted hunks +(~L991, ~L1003) from prior branch WIP before this task; the Phase 2 edit now shares that file. Isolating +the metacache change into its own commit needs care (that file also contains unrelated WIP). +`IcebergCatalogFactory.java` was otherwise clean.

The load-bearing finding this step must fix first: Caffeine coherence per plugin + +The framework's底层 is **Caffeine**. Under the independent-copy strategy, `fe-core` does **not** depend on +`fe-connector-cache`; therefore the framework classes (in the parent-first `org.apache.doris.connector.*` +prefix) resolve **parent → miss (fe-core lacks them) → child**, i.e. they load **child-first from the +plugin's own bundled jar** and link against the **plugin's own bundled Caffeine**. This corrects the P1② +pom note's implicit "single app-loader identity" assumption (true only under the abandoned *move* strategy). + +Consequences (verified against the plugin poms / assemblies / dependency tree): +- **iceberg plugin bundles Caffeine 2.9.3** (from `iceberg-core`; the vendored `DeleteFileIndex` pins it). + The framework was compiled against **3.2.3** → 3.2.3-compiled bytecode running on 2.9.3 = binary-skew risk. +- **paimon plugin bundles NO usable Caffeine** (`com.github.ben-manes.caffeine` absent from its tree; any + paimon-internal caffeine is shaded to `org.apache.paimon.shade.*` and unusable) → loading `MetaCacheEntry` + would `NoClassDefFoundError`. + +**Fix (this step, prerequisite):** +1. Compile `fe-connector-cache` against **Caffeine 2.9.3** (the lowest version any consumer runs — iceberg's), + `provided` (bundles nothing). **Verified: builds + all 20 framework tests green against 2.9.3** → + `MetaCacheEntry`/`CacheFactory` use only APIs present in both 2.9.3 and 3.2.3, so the bytecode is + binary-safe on 2.9.3 (iceberg) and would also run on 3.2.3. +2. **paimon plugin: add `com.github.ben-manes.caffeine:caffeine:2.9.3`** (default/compile scope → bundled in + its plugin zip) so the framework has a Caffeine to link against at runtime. + +fe-core is untouched (it keeps its own `datasource.metacache` + its own 3.2.3). This is Trino-aligned: Trino +plugins are self-contained classloaders that bundle their own dependencies (including caching libs); the SPI +layer stays dependency-free. Keeping `fe-connector-api/spi` Caffeine-free and letting each plugin carry its +own Caffeine matches that model. + +--- + +## 3. Design — thin adapters over `MetaCacheEntry` (surgical) + +Keep each cache class as a **thin adapter** with its existing public method signatures and value types +(`CachedSnapshot`, `ManifestCacheValue`, keys), but replace the internal `ConcurrentHashMap` with a single +`MetaCacheEntry`. This keeps every call site (`IcebergConnector`, `IcebergConnectorMetadata`, +`IcebergScanPlanProvider`, `PaimonConnector`, `PaimonConnectorMetadata`) unchanged. It is the minimal +realization of "port internals onto the framework" (parent design §5) and folds P5 (delete CHM) into the port. + +**Common wiring for all three:** +- `contextualOnly = true`, `loader = null` → the per-call loader is supplied via `entry.get(key, missLoader)`, + matching today's `getOrLoad(key, loader)` shape exactly (the loader closes over the table/handle). +- `autoRefresh = false`, `manualMissLoadEnabled = false`, `refreshAfterWriteSeconds = 0`. No background + refresh (the hand-rolled caches never refreshed); Caffeine `get(key, fn)` gives per-key single-flight (an + improvement over today's "load outside lock, tolerate harmless double-load"), computing on the caller thread. +- `refreshExecutor = ForkJoinPool.commonPool()` (Caffeine's own default). `MetaCacheEntry`'s ctor requires a + non-null `ExecutorService`; commonPool is shared, daemon, needs no lifecycle, and only runs Caffeine's + internal maintenance (never our loader, since loads are synchronous on the caller) → no TCCL concern. +- `invalidate(key)` → `entry.invalidateKey(key)`; `invalidateAll()` → `entry.invalidateAll()`. +- Caffeine `maximumSize` eviction (LRU-ish) **replaces** clear-on-overflow. Safe: all cached values are + reload-safe (latest live snapshot / immutable manifest content). This is the point of adopting the framework. + +**TTL-semantics translation (CRITICAL correctness point — gets a dedicated test):** +The hand-rolled caches treat **`ttl-second <= 0` as "disabled / always read live"**. But `CacheSpec`/ +`MetaCacheEntry` treat **`ttl == -1` as "no expiration (ENABLED)"** and only `ttl == 0` as disabled. So the +adapter must NOT pass a `<= 0` ttl straight through. Mapping: +- latest-snapshot adapters: `ttlSeconds <= 0` → build a **disabled** spec (`CacheSpec.of(true, 0, cap)` → + `isCacheEnabled` false → `get(key, loader)` loads every call, caches nothing = "always live"); else + `CacheSpec.of(true, ttlSeconds, cap)` (access-TTL via `expireAfterAccess`, cap). +- manifest adapter: always enabled, no expiry → `CacheSpec.of(true, CacheSpec.CACHE_NO_TTL, 100_000)` + (`isCacheEnabled(true, -1, 100000)` = true; `toExpireAfterAccess(-1)` = no expiry; cap 100000). The + external enable-gate (`meta.cache.iceberg.manifest.enable`) stays where it is (the scan provider decides + whether to take the manifest-planning path at all); the adapter itself is unconditionally on when consulted. + +**Behavior deviations kept as-is (pre-existing connector simplifications; NOT changed here — surgical):** +- manifest catalog-invalidation does **not** call `ManifestFiles.dropCache(io)` (legacy fe-core did). Flag + as a pre-existing follow-up; not introduced or fixed by this port. +- latest-snapshot value carries only `(snapshotId, schemaId)`, not `IcebergPartitionInfo` (legacy did).

Manual-miss-load (128 striped locks + `invalidateGeneration`) is gated by +`Config.enable_external_meta_cache_manual_miss_load` (`MetaCacheEntry.java:209-261`). + +**Migratability (per-class):** +- **Generic / dependency-free:** `MetaCacheEntryDef`, `MetaCacheEntryStats`, `CatalogEntryGroup`, + `ExternalMetaCacheRegistry`, and `common/CacheFactory` (Caffeine-only content). `MetaCacheEntry` and legacy + `MetaCache` are generic **except** they read 2 `Config` static knobs. `CacheSpec` is generic except its + validators throw fe-core `DdlException` (already forked into `connector-api`). +- **Hard fe-core-bound:** `AbstractExternalMetaCache` (`Env`, `CatalogIf`, `ExternalCatalog/Table`, + `CacheException`), and `ExternalMetaCacheRouteResolver` (**source-specific** `instanceof + IcebergExternalCatalog/HMSExternalCatalog/…`). + +### 2.2 fe-core usage (concrete caches × entries) +`IcebergExternalMetaCache` {`table`,`view`,`manifest`,`schema`}, `HiveExternalMetaCache` +{`schema`,`partition_values`,`partition`,`file` — opts out of predicate invalidation, drives it manually}, +`HudiExternalMetaCache`, `DorisExternalMetaCache` — all constructed once at startup and registered in +`ExternalMetaCacheMgr` (`:290-296`). The highlighted `manifestEntry` = +`contextualOnly(CacheSpec.of(false, CACHE_NO_TTL, 100_000))` (`IcebergExternalMetaCache.java:98-100`). + +### 2.3 Liveness verdict (decisive) +For a **native `type=iceberg`/`type=paimon`** catalog (now `PluginDrivenExternalCatalog`), the **entire +`IcebergExternalMetaCache` — including `manifestEntry` — is DEAD**: +- `ExternalMetaCacheRouteResolver` routes by concrete class; `PluginDrivenExternalCatalog extends + ExternalCatalog` (not `IcebergExternalCatalog`) → routes only to `DefaultExternalMetaCache` + (`ExternalMetaCacheRouteResolver.java:62-80`). +- `PhysicalPlanTranslator` matches `PluginDrivenExternalTable` first → `PluginDrivenScanNode`; the + `IcebergScanNode` branch (`:884`) is dead for these catalogs (`:843-894`). +- `getManifestCacheValue`'s only caller chain is `IcebergManifestCacheLoader` ← `IcebergScanNode` — live + **only for iceberg-on-HMS** (`type=hms`, `DlaType.ICEBERG`), which is deliberately excluded from + `SPI_READY_TYPES`. +- The live manifest cache for PluginDriven iceberg is `IcebergConnector.manifestCache`, dropped by + `PluginDrivenExternalCatalog.onRefreshCache → connector.invalidateAll()` (`:254-263`). + +**LIVE:** `DefaultExternalMetaCache.schema` (serves PluginDriven iceberg *and* paimon schema — PluginDriven +tables inherit engine `"default"`); Hive/Hudi/Doris caches; iceberg-on-HMS's `IcebergExternalMetaCache`. +**DEAD (for native iceberg/paimon):** all of `IcebergExternalMetaCache`'s entries. **Paimon:** has *no* +fe-core meta cache at all (`PaimonExternalMetaCache` was deleted at cutover). + +> So "让 `manifestEntry` 承接 `IcebergManifestCache`" means **reactivating the framework as the owner** of +> the connector's manifest cache — not wiring into a currently-live fe-core entry (it's dead for native +> iceberg). + +### 2.4 Constraints (all verified) +1. **Import gate** (`tools/check-connector-imports.sh`, `fe-connector/pom.xml` validate phase): package-prefix + based — forbids `org.apache.doris.{catalog,common,datasource,qe,analysis,nereids,planner}` in connectors, + whitelists `thrift|connector|extension|filesystem`. A generic class is blocked purely by its package, so + any shared class must re-home under `org.apache.doris.connector.*`. +2. **Caffeine / zero-third-party charter:** `fe-connector-api` and `fe-connector-spi` declare **zero** + third-party deps (spi pom: *"Zero third-party external dependencies — only JDK and Doris internal SPI + interfaces"*). fe-core has Caffeine 3.2.3; the **iceberg plugin uses Caffeine 2.9.3** (declared compile, + vendored `DeleteFileIndex`) and plugin zips bundle 3.2.3 child-first. Putting Caffeine on the connector + classpath breaks the charter **and** re-opens the classloader split-brain (cf. MEMORY + `catalog-spi-plugin-tccl-classloader-gotcha`). +3. **Plugin-zip single identity:** the assembly excludes `fe-connector-api/spi`, `fe-extension-spi`, + `fe-filesystem-api` → these load once on the app classloader (single `Class` identity across the + boundary). Caffeine is **not** excluded → stays duplicated per plugin. +4. **fe-core depends on `fe-connector-api` + `fe-connector-spi`** (`fe-core/pom.xml:100-110`) → a class placed + there is usable by both sides. `ConnectorContext` (connector-spi) is the existing fe-core→connector + injection seam: it already exposes `getMetaInvalidator()→ConnectorMetaInvalidator.NOOP` (`:105`) and + `executeAuthenticated` (the TCCL-pin entry, `:94`). + +--- + +## 3. Goals / non-goals + +**Goals** +- One meta-cache abstraction serving both fe-core-hosted engines and plugin connectors — connectors stop + hand-rolling `ConcurrentHashMap` caches and reuse the framework (Caffeine eviction, TTL, refresh, stats, + invalidation semantics). +- Collapse the `CacheSpec` fork (connector-api mirror vs fe-core original) to a single source of truth. +- Preserve today's REFRESH CATALOG/TABLE invalidation semantics and the `<= 0 ttl disables` behavior. + +**Non-goals** +- Not migrating iceberg-on-HMS off the legacy path in this change (keeps `IcebergExternalMetaCache` live + there; its native-iceberg entries stay dead-but-present until hms flips). +- Not changing hive/hudi/doris cache behavior (their catalogs haven't flipped). +- Not moving the `Env`/catalog-coupled framework core (`AbstractExternalMetaCache`, `RouteResolver`) out of + fe-core. + +--- + +## 4. Architecture options + +The fork below **determines everything else**. All three satisfy the goal of "one abstraction"; they differ +on *where the cache lives* and *what crosses the boundary*. + +### Option A — Move the generic framework into a shared connector module; connectors OWN caches ✅ CHOSEN +Move `CacheFactory`+`CacheSpec`+`MetaCacheEntry`+`MetaCacheEntryDef`+`MetaCacheEntryStats`+ +`MetaCacheEntryInvalidation`+`CatalogEntryGroup`+`ExternalMetaCacheRegistry` into +`org.apache.doris.connector.api.cache`, **add Caffeine to `fe-connector-api`**, inject the 2 `Config` knobs. +fe-core keeps `AbstractExternalMetaCache`/`RouteResolver`/`Mgr`/concrete engine caches and imports the moved +core. +- ✅ Single source of truth; connectors get the full Caffeine machinery (Caffeine eviction, `refreshAfterWrite`, + stats, striped-lock miss-load) locally; collapses the `CacheSpec` fork. +- ✅ **Split-brain is AVOIDABLE (verified post-decision).** `ConnectorPluginManager` loads + `org.apache.doris.connector.*` **parent-first** (`:64-65`) → the moved framework classes have a **single + app-loader identity**. `MetaCacheEntry`'s cross-boundary API is **Caffeine-free** (Caffeine is internal; + `stats()` returns the generic `MetaCacheEntryStats`), so the framework's app-loader Caffeine never meets the + plugin's child-first Caffeine (iceberg's vendored 2.9.3, used only by `org.apache.iceberg.*` child-loaded + code). They coexist without sharing objects. +- ⚠️ **The load-bearing rule that keeps it safe:** connectors must interact **only** through the Caffeine-free + `MetaCacheEntry` API. `CacheFactory`'s public API *returns* Caffeine types (`LoadingCache`), so it must + stay **framework-internal** — a connector calling it directly would receive an app-loader Caffeine object + that its child-first loader re-resolves → ClassCast (the MEMORY tccl-gotcha failure mode). +- ⚠️ **Real remaining costs:** (1) adds Caffeine as a compile dep to `fe-connector-api` — **breaks the stated + "zero third-party dependencies" charter** (a policy change, technically clean under parent-first). (2) Inject + the 2 `Config` knobs into `MetaCacheEntry` (ctor params) since it cannot read fe-core `Config`. (3) Blast + radius: **~16 fe-core files** import the framework/`CacheFactory` (iceberg×3, hive×2, hudi, doris, + `ExternalCatalog`/`ExternalDatabase`/`ExternalMetaCacheMgr`, `property/metastore`, `tablefunction`) plus the + 2 non-metacache `CacheFactory` callers (`ExternalRowCountCache`, `FileSystemCache`) — all mechanical import + updates + the ctor-knob threading. (4) `SchemaCacheValue`→`catalog.Column`: keep the schema-value concern in + fe-core's `AbstractExternalMetaCache` (don't drag `Column` connector-visible). + +### Option B — fe-core keeps owning caches; connector delegates via an SPI handle on `ConnectorContext` ✅ RECOMMENDED +Keep the whole framework in fe-core. Add a **dependency-free** handle in `fe-connector-spi`: +```java +public interface ConnectorMetaCache { + V get(K key, java.util.function.Supplier loader); // contextual miss-load + V getIfPresent(K key); + void invalidate(K key); + void invalidateAll(); + // stats() optional +} +``` +obtained via a new `ConnectorContext.getMetaCache(String entryName, CacheSpec defaultSpec)` (default returns +a trivial no-cache impl for back-compat), **implemented in fe-core by wrapping a `MetaCacheEntry`**. +Connectors delete their `ConcurrentHashMap` caches and call the injected handle; `IcebergManifestCache` +becomes a thin caller of a fe-core-backed `MetaCacheEntry` — i.e. `manifestEntry` *承接* it. Only a neutral +interface + the already-dependency-free `CacheSpec` cross the boundary — **no Caffeine crosses**. +- ✅ Satisfies **all three** hard constraints at once (import gate, zero-third-party charter, Caffeine + split-brain); ✅ reuses fe-core framework + `Config` knobs + stats + striped-lock miss-load; ✅ matches the + existing `ConnectorContext` seam direction and TCCL-pin machinery; ✅ **directly realizes the user's + "manifestEntry 承接" framing**; ✅ smallest blast radius (mostly *reactivates* dead fe-core code for the + connector rather than touching hot paths). +- ⚠️ Cache **state lives in fe-core** keyed by connector-supplied keys → value/key types are generic `` + (or `Object` + cast) across the seam; loader lambdas re-enter connector code → **must pin TCCL** (machinery + exists: `TcclPinningConnectorContext`); per-cache plumbing to wire each entry. + +### Option C — Hybrid: shared dependency-free *declaration* layer, fe-core-hosted Caffeine +Promote only the dependency-free declaration classes (`CacheSpec`, `MetaCacheEntryDef`, `Stats`, +`MetaCacheEntryInvalidation` minus `forNameMapping`, `Registry`, `CatalogEntryGroup`) to connector-api as a +shared vocabulary; keep `MetaCacheEntry`/`CacheFactory`/Caffeine in fe-core behind the Option-B handle. +Connectors *author* full `MetaCacheEntryDef`s; fe-core materializes them. +- ✅ Collapses the `CacheSpec` fork and gives connectors real def/invalidation vocabulary, no Caffeine on the + connector classpath. ❌ Two-layer split = more moving parts; marginal benefit over B unless connectors need + to author full defs/predicates rather than consume a get/invalidate handle. + +### Decision & recommendation +The research pass recommended **B** (least blast radius, keeps the charter). The user chose **A** (single +source of truth; connectors self-contained). Post-decision verification **de-risked A's headline objection**: +the Caffeine split-brain is avoidable (parent-first `org.apache.doris.connector.*` + Caffeine-encapsulated +`MetaCacheEntry`), so A is viable. The residual, accepted trade-off is the **"zero third-party" charter break** +on `fe-connector-api` (Caffeine compile dep) plus the ~18-file mechanical blast radius. The §5 plan below is +for **Option A**. + +--- + +## 5. Proposed migration (Option A) — phased + +> Ordering: move the framework first (no behavior change), then port each connector cache onto it, then +> collapse the duplicates and dead code. Each phase is independently buildable/testable and a separate commit. +> Guiding invariant: **connectors touch only the Caffeine-free `MetaCacheEntry` API; `CacheFactory` and any +> Caffeine-typed API stay framework-internal.** + +**P1 — relocate the generic framework to `org.apache.doris.connector.api.cache` (no behavior change).** +Move `CacheFactory`, `MetaCacheEntry`, `MetaCacheEntryDef`, `MetaCacheEntryStats`, +`MetaCacheEntryInvalidation` (drop the `NameMapping`-coupled `forNameMapping` factory, or move `NameMapping` +too — §6 Q3), `CatalogEntryGroup`, `ExternalMetaCacheRegistry`, and the single `CacheSpec`. Change +`MetaCacheEntry` to take the 2 knobs as ctor params (`refreshAfterWriteSeconds`, +`manualMissLoadEnabled`) instead of reading `Config`. Add Caffeine as a `fe-connector-api` compile dep. Update +the ~16 fe-core importers + the 2 `CacheFactory` callers (`ExternalRowCountCache`, `FileSystemCache`) to the +new package; fe-core call sites pass the `Config`-derived knob values (so fe-core behavior is byte-identical). +Keep `AbstractExternalMetaCache` (Env/catalog glue) + `ExternalMetaCacheRouteResolver` + `Mgr` + concrete +`*ExternalMetaCache` in fe-core, now importing the moved core. Collapse the connector-api `CacheSpec` mirror +into this one shared copy (validators throw `IllegalArgumentException`; fe-core's dead `checkLongProperty` +callers need no change — §6 Q4). **Gate:** `check-connector-imports.sh` green (moved classes are under the +whitelisted `connector.` prefix); full fe-core + connector build green; all existing cache tests unchanged. + +**P2 — connector cache-construction helper.** Give connectors a small, Caffeine-free way to build a +per-catalog cache without the Env-coupled `AbstractExternalMetaCache`: either a thin +`MetaCacheEntry` builder taking `(name, CacheSpec, refreshExecutor, knobs)`, or expose a +`ConnectorContext.getSharedRefreshExecutor()` so the plugin reuses fe-core's `commonRefreshExecutor` (avoids a +per-connector thread pool). Decide executor ownership (§6 Q5). Connectors keep OWNING the cache instance +(field on `IcebergConnector`/`PaimonConnector`, dropped on rebuild/REFRESH). + +**P3 — port the latest-snapshot caches.** Replace `IcebergLatestSnapshotCache` /`PaimonLatestSnapshotCache` +internals with a `MetaCacheEntry` (access-TTL from `meta.cache..table.ttl-second`, capacity 1000), +keeping their key/value types (`TableIdentifier`/`Identifier` → `CachedSnapshot`/`long`). Decide the +`IcebergPartitionInfo` fidelity gap (§6 Q6). `Connector.invalidateTable/invalidateAll` → `entry.invalidateKey/ +invalidateAll`. + +**P4 — port the manifest cache.** Replace `IcebergManifestCache` with a `contextualOnly` `MetaCacheEntry` +(`CacheSpec.of(false, CACHE_NO_TTL, 100_000)`, `get(key, missLoader)`); unify `ManifestCacheValue` + +`IcebergManifestEntryKey` into one shared copy (already byte-identical ports — move to a connector-visible +package both sides use). Preserve "REFRESH TABLE keeps the manifest cache" (invalidateTable skips it), and +decide the `ManifestFiles.dropCache(io)` fidelity gap (§6 Q6). + +**P5 — collapse duplicates + dead code.** Delete the connector `ConcurrentHashMap` cache classes; optionally +prune the now-dead native-iceberg `IcebergExternalMetaCache` entries (kept only for iceberg-on-HMS until hms +flips — §6 Q7). + +**Testing.** Unit: `MetaCacheEntry` behavior after the Config-knob extraction (TTL/capacity/invalidate/ +miss-load) in its new home; the ported connector caches (TTL expiry via injectable clock as today). Regression: +`test_iceberg_table_meta_cache` / `test_paimon_table_meta_cache` (stale-vs-refresh row counts) and +`IcebergScanPlanProviderTest` (manifest path) stay green. **Classloader:** an explicit test/redeploy check that +a plugin-built `MetaCacheEntry` runs against app-loader Caffeine and never receives a `CacheFactory`/Caffeine +object across the boundary (guards the one failure mode that makes A unsafe — cf. MEMORY tccl-gotcha). + +--- + +## 6. Remaining decisions (Option A) for the user +The ownership fork (Q1) and Caffeine-on-classpath (Q2) are **settled by choosing A**. These remain: + +1. **Charter break — confirm.** Adding Caffeine as a `fe-connector-api` compile dep breaks its stated + "zero third-party dependencies" charter. Verified split-brain-safe (parent-first + encapsulation), but it is + a real policy change to the SPI module. Accept? (Alternative to soften it: put the framework + + Caffeine in a *new* module `fe-connector-cache` under `org.apache.doris.connector.*` — still parent-first, + keeps `-api`/`-spi` pure. **Recommended.**) +2. **Target module** — `fe-connector-api` (existing, but breaks its charter) vs a **new `fe-connector-cache`** + module (keeps `-api`/`-spi` dependency-free; both are parent-first via the `connector.` prefix). Recommend + the new module. +3. **`MetaCacheEntryInvalidation.forNameMapping`** — it couples to `datasource.NameMapping`. Drop that factory + (connectors don't need it; fe-core keeps its own), or move `NameMapping` to a connector-visible package too? +4. **`CacheSpec` collapse** — one shared copy in the new home; validators throw `IllegalArgumentException` + (fe-core's only `checkLongProperty` callers are dead). Confirm this is the surviving behavior. +5. **Refresh executor ownership** — connectors reuse fe-core's `commonRefreshExecutor` via a new + `ConnectorContext.getSharedRefreshExecutor()` (no extra plugin thread pool) vs each connector owns one. + Recommend sharing fe-core's. +6. **Behavior/fidelity parity** — porting to `MetaCacheEntry` *upgrades* connector caches from + clear-on-overflow to real Caffeine eviction (+ optional `refreshAfterWrite`/stats). Adopt the richer + behavior, or configure to match today exactly (no refresh, no stats)? Also: re-add + `ManifestFiles.dropCache(io)` on catalog invalidation and `IcebergPartitionInfo` in the snapshot value, or + keep the connector's current simplifications? +7. **Dead-code + paimon scope** — prune the now-dead native-iceberg `IcebergExternalMetaCache` entries now (or + keep while iceberg-on-HMS stays legacy)? And is paimon in scope this round (it needs a *new* snapshot entry, + not a wrap of an existing one), or iceberg-first? + +--- + +## 7. Risks / open questions +- **The one failure mode that makes A unsafe:** a Caffeine-typed object (`LoadingCache` from `CacheFactory`, + or a raw `Cache`) crossing to connector (child-first) code → ClassCast. Mitigation: keep `CacheFactory` + package-private / framework-internal; connectors use only the Caffeine-free `MetaCacheEntry` API; add a + redeploy classloader smoke test (MEMORY `catalog-spi-plugin-tccl-classloader-gotcha`). +- **Caffeine version skew** — iceberg's plugin compiles against caffeine **2.9.3** (vendored `DeleteFileIndex`, + child-first, `org.apache.iceberg.*`); the framework uses app-loader **3.2.3**. Safe *because* they never + share objects — but confirm no plugin code passes a 2.9.3 cache into a framework call. +- **iceberg-on-HMS keeps `IcebergExternalMetaCache` LIVE** — its native-iceberg entries are dead but the class + can't be deleted until hms flips; the moved framework must keep serving it unchanged. +- **`SchemaCacheValue` → `catalog.Column`** — the schema-value concern stays in fe-core's + `AbstractExternalMetaCache`; do not move `getSchemaValue`/`wrapSchemaValidator` (would drag `Column` + connector-visible). +- **Hive invalidation asymmetry** — Hive uses `none()` + manual partition-granular `invalidate*`; the move must + not assume uniform predicate invalidation (don't regress hive). +- **Load-bearing, re-verify before coding:** the exact `getOrLoad` loader bodies in + `Iceberg/PaimonConnectorMetadata.beginQuerySnapshot`; and whether metadata/sys-table queries against a + PluginDriven iceberg catalog secretly depend on the dead `IcebergExternalMetaCache` path. + +--- + +## 8.

的第二份解析，非新建模块） + +1. **`fe-filesystem-api/spi` 已是插件可用的共享存储契约**（Trino-SPI 式）：`org.apache.doris.filesystem.*` 对连接器插件**强制 parent-first**（`ConnectorPluginManager:64-65`），已是 fe-connector-spi/paimon 的 compile-dep，且 plugin-zip **排除打包**（`plugin-zip.xml:48`）。**接口无须从 fe-core 抽取**，解析器（fe-filesystem-{s3,oss,cos,obs,azure,hdfs,broker} 的 `FileSystemProvider.bind`）**本就在 fe-core 之外**。 +2. **连接器读/扫描路径已是 fe-filesystem-native**：iceberg/paimon `buildStorageHadoopConfig` 迭代 `context.getStorageProperties() → sp.toHadoopProperties()`；scan provider 由 `sp.toBackendProperties().toMap()` 出 `location.*` BE 凭据。 +3. **fe-core `datasource.property.storage.StorageProperties.createAll` 是冗余的第二份解析**（同一 raw props 被解析两遍）：(a) fe-core createAll（`CatalogProperty.initStorageProperties:211`）；(b) fe-filesystem `FileSystemFactory.bindAllStorageProperties`（连接器经 `context.getStorageProperties()` 触发）。 +4. **持久化/展示只用 raw map**：GSON 只存 `CatalogProperty.properties`（raw）；SHOW CREATE / information_schema 渲染 **raw masked map**（`DatasourcePrintableMap` over `getProperties()`），从不用解析值。 +5. **BE thrift 已可插件直建**：连接器已 by-reference 就地改 per-split（`populateRangeParams`）/scan-level（`populateScanLevelParams`）thrift 再转发 BE；fe-thrift 对 fe-connector-api 是 provided-scope，插件本可直建 thrift。 + +## 1. 目标架构 + +- **单一真相源** = fe-filesystem bind（storage）+ fe-connector-metastore（meta）。为**插件 catalog**，fe-core 退掉自己的 `StorageProperties.createAll` + `Paimon*/Iceberg* MetastoreProperties` 簇。 +- **fe-core 仅保留**：raw catalog map（展示 + 回放）、一个 `bindStorage` **调用**接缝（调 fe-filesystem，不自己解析）、非 null 的 no-op ExecutionAuthenticator handle、以及不可约的引擎接缝（broker 地址注入 `Env.getBrokerMgr`、`String-map→THdfsParams` 的 `HdfsResource.generateHdfsParam`、fe-core 自己的 FS 操作 `SpiSwitchingFileSystem`）。 +- **插件→fe-core 回传契约**：(1) 展示 = raw props + **敏感键集合**（供脱敏）；(2) 回放 = raw props（已满足）；(3) 扫描 = 已回传的成品（`ScanNodePropertiesResult` + by-reference thrift）；(4) 存储成品 = 插件**返回** BE 凭据/配置 map（真正的 gap，取代 fe-core 从 `getStoragePropertiesMap()` 派生）；(5) 鉴权 = 插件独占 Kerberos，fe-core 只留非 null no-op handle（因 `BaseExternalTableInsertExecutor:113/185` 无条件调 `getExecutionAuthenticator().execute()`，且 `ExternalCatalog:1391` null 会抛）。 + +## 2. 中央决策（**✅ 用户 2026-07-05 裁定 = A 家族：共享宿主 classpath + 连接器发起 bind**）= bind-location fork + +> **裁定落地**：fe-filesystem 解析器留在宿主 classpath（parent-first、不打包）；**连接器直接调 fe-filesystem-api 发起 bind**（它已 compile-dep fe-filesystem-api），不经 fe-core context round-trip；fe-core 零解析。即下方 A，且取"连接器发起"变体（非 fe-core context 发起）。**B 不采纳。** + +### （备查）原 fork 权衡 + +**fe-filesystem 解析器放哪？** +- **A（引擎宿主单 `bindStorage(raw)` 接缝，recon 推荐）**：fe-filesystem provider 留在 fe-core 的宿主 classpath（`DirectoryPluginRuntimeManager`），连接器经 context 调 bind。**满足"fe-core 不解析"**（解析器是独立 fe-filesystem 插件），近乎 drop-in（paimon 已 `toBackendProperties().toMap()`），无 AWS-SDK/hadoop 重复、无 TCCL split-brain。**代价**：fe-core 物理上仍在 bind **调用**路径上（但不解析）。 +- **B（每插件自打包 fe-filesystem impl，fe-connector-cache 式 child-first）**：字面"在连接器 classloader 内解析"，但**每个连接器 + 独立 FS 插件都重复 AWS-SDK v2 + hadoop-common/aws**，重新引入隔离架构专门规避的 TCCL/split-brain 冲突。 + +> **待用户定**：A 满足"fe-core 零解析"的**实质**（解析在 FS 插件里），但 fe-core 仍是 bind 的**调用方**；B 是字面"连接器内解析"但代价大。recon + 我推荐 **A**。若你的"全部由插件完成"要求连接器**自己发起** bind（而非经 fe-core 的 context），A 也可微调为"连接器直接调 fe-filesystem"（连接器已 compile-dep fe-filesystem-api）——这仍是 A 家族，不落 B 的重复。 + +## 3. 其余决策（recon 推荐 default，本设计采纳，除非上面 fork 改变） +- **URI-normalize + TFileType**：先保留 fe-core 薄接缝（String-in/out、不含 catalog-specific 解析）；只有硬要求"fe-core 零存储码"才 port 进 fe-filesystem-api（低优先）。 +- **BE-thrift 方向**：HDFS/kerberos 保持 INDIRECT（仅 `THdfsParams` 需 typed build，留 `HdfsResource.generateHdfsParam` 单一 fe-core 转换器）；S3/对象存储已是 `params.setProperties(map)`。原则"插件→BE thrift"已由 by-reference populate* 接缝结构性满足。 +- **vended "跳过静态表"信号**：fe-core 对**所有插件 catalog 无条件不建静态存储表**（插件 100% 拥有 static+vended，precedence 已在扫描路径连接器侧）。**这直接解掉此前卡住的 vended 难题**——不判别、不 gate、不读 iceberg 键，彻底删净且守铁律。 +- **fe-core auth handle** = no-op pass-through（getExecutionAuthenticator 只须非 null）。 + +## 4. 迁移刀序（每刀独立 commit + build + test + checkstyle + import-gate；**先 parity 验证再删 fe-core 路**） +- **S1**：无（fe-filesystem-api/spi 已插件可用，**别抽取**）。 +- **✅ S2（`a00ca592ba3`）**：`getStorageProperties()` 改绑 raw props 直传，去掉 `getStoragePropertiesMap()→getOrigProps()` round-trip（fe-core 第二份解析退出该路）。落地=`CatalogProperty` 抽 `shouldBuildStaticStorage`+`mergeDerivedStorageDefaults` 两共用私有方法（解析路 `initStorageProperties` 与新 public `getEffectiveRawStorageProperties` 共用→两路 map 逐字节相同，createAll origProps 原样透传不 mutate 已核实）；`DefaultConnectorContext` 加 `rawStoragePropsSupplier`+5-arg ctor（typed supplier 保留供 S3/S5 未迁消费者）；`PluginDrivenExternalCatalog` 唯一生产接线改 5-arg。**derived defaults（warehouse→defaultFS）保住**（`mergeDerivedStorageDefaults` 内，msp!=null 用 msp、msp==null 用中立 helper）。`getEffectiveRawStorageProperties` 包 `synchronized(this)` 保 metastore+props 单一致快照（对齐解析路原子性，防并发 ALTER warehouse 撕裂派生值；对抗复审 refuted 后主动硬化）。验收=fe-core BUILD + 新/改 7 测 + mutation 3/3 KILLED + checkstyle 0 + 3 视角对抗复审 0 confirmed。⚠️ BE `location.*` map parity 由构造保证（非 e2e）；重部署 classloader 冒烟 flip-gated 未跑。 +- **✅ S3（`72680f03995`）**：iceberg WRITE 路 `IcebergWritePlanProvider.buildHadoopConfig` 的 BE 静态凭据从 fe-core `context.getBackendStorageProperties()` 改到 fe-filesystem 形（遍历 `context.getStorageProperties()` 取 `toBackendProperties().toMap()`），与扫描路径同源。**parity 核对（代码级 + 扫描线上存在性证明）**：带凭据的对象存储/HDFS 写认证键逐字节一致、HDFS 派生默认值一致；唯一非逐字节差异是老路经 createAll 默认注入的 HDFS 兜底多带两个 BE 对象存储写不读的惰性键，新路不带（扫描早已在用新形且线上，即证够用）。验收=fe-connector-iceberg 939 测 0 失败 + 写测 41 mutation KILLED + checkstyle 0 + import 门禁净。S10 铁律：`CatalogProperty.getBackendStorageProperties` 保活。 +- **✅ S4（`f2976900852`，用户裁定「彻底退休」）**：删 `VendedCredentialsFactory`/`AbstractVendedCredentialsProvider`/`IcebergVendedCredentialsProvider`（+3 测）；删 `CatalogProperty.shouldBuildStaticStorage` gate，`initStorageProperties`+`getEffectiveRawStorageProperties` 无条件走 `mergeDerivedStorageDefaults`；`IcebergScanNode`(legacy HMS) 改直读 `getStoragePropertiesMap()`（HMS-typed 恒 null，逐字等价）；删门移除后已死的 `MetastoreProperties.isVendedCredentialsEnabled()`(+PaimonRest 覆写)。**行为变化（用户已接受，flip-gated）**：vended 目录若同时配静态 key，语义由「vended 取代静态」变「vended 叠加静态」（同名仍 vended 优先、最终认证不变，仅额外仅静态键也发 BE）；纯 REST 无变化。验收=fe-core 113 测 0 失败 + checkstyle 0 + import 净。S10 铁律：静态 map 四方法 + createAll 全保活。 +- **✅ S5（决策落地，无代码）= 保留 fe-core 薄接缝（用户裁定「保留现状」）**：`normalizeStorageUri`/`getBackendFileType` 已是引擎中立（String 进出、无引擎名分支），仅复用已解析存储做 `LocationPath` 规范化/文件类型判定。fe-filesystem 无等价 API（`LocationPath`/`TFileType` 均 fe-core-only，且 fe-filesystem 刻意无 Thrift），迁移需新建规范化/中立文件类型 API + 复刻 MinIO/Ozone/Azure 兼容分支 + 重跑读写端到端（对合并读删路径有正确性风险），无硬性「fe-core 零存储码」要求故不做。低优先，将来若硬性要求再评估。 +- **✅ S6（前置 `498d3230916` + 落地 `12599958bce`，用户裁定「本 session 完整做掉，接受 flip-gated 风险」）**：**前置**=paimon 连接器补 HMS 元存储 Kerberos 鉴权器（抽 `PaimonConnector.buildPluginAuthenticator` 静态、镜像 iceberg CUT1、新增 HMS-Kerberos-简单存储分支 + 5 单测），补齐「paimon 缺 HMS 鉴权器」这一 blocker。**落地**=删 `PluginDrivenExternalCatalog.initPreExecutionAuthenticator` 重写→继承基类 no-op（插件 catalog 的 fe-core handle 非空但不做 doAs，真 doAs 在连接器 TcclPinningConnectorContext）；删无调用方的 `CatalogProperty.getOrderedStoragePropertiesList` getter + 内联其字段。验收=fe-core 375 测 0 失败 + paimon 5 测 + 双 checkstyle 0 + import 净。**⚠️ flip-gated**：端到端 Kerberos（对真 KDC 的 doAs）本地无集群不可验，单测只证「鉴权器已构建 + 句柄非空 + 插入不崩」。legacy（HMS-iceberg/hive/hudi）真鉴权器不受影响；`MetastoreProperties.initExecutionAuthenticator` 生产已无调用方但保留待 S7。 +- **✅ S8（`3e7a687e6e2`，先于 S7 落地=其前置）**：CUT4 的 `deriveHdfsDefaultFsFromWarehouse` **搬进连接器**。**机制精化（对原「搬回 fe-connector-metastore-iceberg」的更正）**：recon 实证——插件存储绑定走 fe-core `DefaultConnectorContext.getStorageProperties()`（fe-core 在连接器被咨询前就已 bind），且同一 `mergeDerivedStorageDefaults` 同时喂 FE 绑定 + BE typed map，故派生**必须经一个中立 SPI 回填 fe-core 的 storage map**，否则 FE/BE 存储分叉。落地=新增 `Connector.deriveStorageProperties(rawProps)`（默认空，在 fe-connector-api），`IcebergConnector`（fe-connector-iceberg，非 metastore 子模块）override 实现 hadoop-flavor warehouse→fs.defaultFS（仅 hadoop 派生、逐字节镜像旧 override）；`PluginDrivenExternalCatalog` 经 `CatalogProperty.setPluginDerivedStorageDefaultsSupplier` 懒折叠。`CatalogProperty.mergeDerivedStorageDefaults` 无参化 + `resolveDerivedStorageDefaults`：插件 catalog 走 supplier（不调 getMetastoreProperties），legacy 走 msp。删 fe-core 中立 helper + 其测。 +- **✅ S7（`3c69bfa8265`，−4914 行）**：退 fe-core `Paimon*/Iceberg* MetastoreProperties` 簇 + un-register `Type.PAIMON/ICEBERG`（`MetastoreProperties:90-91` register 行删，枚举值留=fail-loud）。**recon 对抗核验揪出的 compile 扩面（本设计一句话原漏）**：iceberg 5 类被 `datasource/connectivity/` 子系统硬引用（`CatalogConnectivityTestCoordinator` + 5 iceberg 探测器），该子系统对 legacy Hive 仍活但 iceberg 分支翻闸后死——故 S7 须**同刀删 5 探测器 + 摘协调器 iceberg 分支/import**（Hive 保留）。另删 property/common 2 凭据类（IcebergAwsAssumeRole/ClientCredentials，仅簇内消费）+ 死方法 `initExecutionAuthenticator` + 14 簇单测；迁 `CatalogPropertyEffectiveRawStoragePropsTest` 到 supplier 路。**连接器零影响**（无 fe-core import，验证）。 +- **✅ S9（决策，无代码）**：BE-thrift 保持现状（INDIRECT 默认）。插件 iceberg/paimon 的 BE thrift **已全在连接器侧** by-reference `populate*` 建（`{Iceberg,Paimon}ScanRange/ScanPlanProvider.populate*`；fe-core 无 paimon 包；`IcebergScanNode.setIcebergParams` 只服务 legacy HMS-iceberg）；HDFS/kerberos 唯一 typed build `HdfsResource.generateHdfsParam` 留 fe-core。原则已结构性满足，无须动码。 +- **✅ S10（铁律验证，无代码）**：`CatalogProperty` 的 getStoragePropertiesMap/getBackendStorageProperties/getHadoopProperties/getMetastoreProperties + `initStorageProperties` + fe-core `StorageProperties.createAll` + 共享基类（HMSBaseProperties/AWSGlueMetaStoreBaseProperties/AliyunDLFBaseProperties/AbstractMetastorePropertiesFactory）**实测全保活**，供 Hive/Hudi/LakeSoul/HMS-iceberg 直读解析出 BE thrift（`HiveScanNode:559`/`HudiScanNode:252,425`/`HiveTableSink:133,164`/`IcebergUtils:1309`）。**S7 只 repoint 插件路，未删任何共享方法。** + +> **✅✅ S1–S10 全部完成 = 已迁连接器（iceberg+paimon）属性解析全归插件、fe-core 零解析目标达成。** 未迁连接器（Hive/Hudi/LakeSoul/HMS-iceberg）暂留 fe-core 解析残留（S10 保活），随其离 SPI（阶段四）再清。 + +## 5. 三刀对账 +- **CUT1（`cf8dda9f058` 连接器自建 HMS 鉴权）**：方向对；当前 additive（fe-core 仍并行建）。S6 收尾：退 fe-core parse + handle 降 no-op（不能删，插入-提交路 `BaseExternalTableInsertExecutor:113/185` 用它）。⚠️ 需确认 fe-core authenticator 对 insert-commit 是死重还是 load-bearing（无 live Kerberos e2e）。 +- **CUT2（`eb9201dc0a6` SHOW CREATE 脱敏）**：**层对、保留**（展示是 fe-core-owned raw map）。仅改敏感键**来源**：现 fe-core 硬编 4 键（"keep in sync"注释脆），目标=插件**返回**敏感键集经**既有** `DatasourcePrintableMap.registerSensitiveKeys` 通道注册（FS provider 启动时已这么做）。CUT2 = 正确层 + 临时硬编 + 待换连接器供源。 +- **CUT4（`0de34db83fb` warehouse→fs.defaultFS helper 在 fe-core）**：**方向反**（fe-core 解析 storage）。S8 搬回 fe-connector-metastore-iceberg；**与 S6-S8 一起搬、不早于**（现仍对 HA native-iceberg load-bearing）。 + +## 6. 风险 / 验证门（每刀） +- **classloader/bundling**：方案 A 全靠 `org.apache.doris.filesystem.*` parent-first 保 StorageProperties 单类身份。⚠️ 未验：`FileSystemFactory.bindAll` bind() 时是否 pin TCCL 到 FS 插件 loader 使 provider 内部反射解析插件自带 AWS/hadoop——依赖 A 前须确认。 +- **double-parse drift**：write（fe-core parse）vs scan（fe-filesystem bind）两路到 BE-canonical map，repoint write 前**须逐字 parity diff**；derived defaults 仅现于 fe-core parse，fe-filesystem bind 须复现否则 HDFS-HA/warehouse-only 回归。 +- **paimon 同范围**：非 iceberg-only；且共享码仍服务 legacy Hive/Hudi/LakeSoul/HMS-iceberg（S10 保命）。 +- **auth 冗余/正确性**：降 no-op 前须证连接器 pluginAuthenticator 覆盖 commit/abort，否则静默丢 Kerberos（flip-gated）。 +- **flip-gated e2e**：全在插件路、无 green Kerberos-HDFS e2e；每刀门 = 重部署 classloader 冒烟 + BE `location.*` map parity diff（fe-core 路 vs

FIX 1 — fe-core generic DDL invalidation hook (D1) + +### 1.1 The bug (HEAD-verified) +`PluginDrivenExternalCatalog`'s schema-level DDL overrides never reach `connector.invalidate*`: +- `dropTable` (`:536-596`) ends at `metadata.dropTable` + `logDropTable` + `unregisterTable` (`:593-594`); + the view branch (`:565-575`) ends at `dropView` + `unregisterTable` (`:572`). +- `createTable` (`:380-443`) ends at `metadata.createTable` + `logCreateTable` + `resetMetaCacheNames` + (`:439`). +- `dropDb` (`:500-525`) ends at `metadata.dropDatabase` + `logDropDb` + `unregisterDatabase` (`:523`). + +`unregisterTable`/`unregisterDatabase`/`resetMetaCacheNames` touch only the fe-core ENGINE caches +(`ExtMetaCacheMgr`), never the connector-owned caches. The ONLY paths that reach `connector.invalidate*` +are the three REFRESH verbs (`RefreshManager.refreshTableInternal:245-257` REFRESH TABLE — also reached by +TRUNCATE and ALTER via `afterExternalDdl`; `refreshDbInternal:119-129` REFRESH DATABASE; +`onRefreshCache:252-261` REFRESH CATALOG). So a Doris-issued `DROP TABLE t; CREATE TABLE t (...)` (or the +DB equivalent) keeps serving the dropped object's cached metadata/snapshot until the 24h TTL. + +Two victims, different severity: +- **hive** — dormant (`"hms"` not in `SPI_READY_TYPES`); latent until the flip. +- **paimon/iceberg** — **LIVE**: `IcebergLatestSnapshotCache` / `PaimonLatestSnapshotCache` (key = plain + `(db,table)`, value = pinned `(snapshotId[,schemaId])`, 86400s **access**-based TTL) pin the DROPPED + table's snapshot onto the recreated same-name table until the TTL (kept alive by continuous querying). + +### 1.2 Trino parity (per the user's request to consult Trino — recon-confirmed) +Trino's `CachingHiveMetastore` self-invalidates synchronously after every `createTable`/`dropTable`/ +`dropDatabase`/`replaceTable`/`renameTable`/`update*Statistics` (a `finally`-block +`invalidateTable`/`invalidateDatabase`). D1 puts the same eager invalidation at the natural Doris seam — +the generic `PluginDrivenExternalCatalog` DDL entry — so it lands once for every SPI connector instead of +per-plugin. + +### 1.3 The change +Add, immediately after each successful mutation (using the already-non-null `connector` field these methods +already dereference, and the REMOTE names — the exact form `RefreshManager` passes and the connectors key +on): +- `dropTable` table branch (after `metadata.dropTable`, `:590`) → + `connector.invalidateTable(dorisTable.getRemoteDbName(), dorisTable.getRemoteName())`. +- `dropTable` view branch (after `dropView`, `:570`) → same call (harmless no-op if the connector has no + entry for a view; keeps the two branches uniform). +- `createTable` (after `metadata.createTable`, `:427`) → + `connector.invalidateTable(db.getRemoteName(), createTableInfo.getTableName())`. The table name is NOT + remote-resolved (parity with the existing code: a new table has no local→remote mapping). +- `dropDb` (after `metadata.dropDatabase`, `:519`) → `connector.invalidateDb(db.getRemoteName())`. + +**`dropTable` is the load-bearing call** for the drop+recreate bug (it clears the stale pin so the later +`CREATE`'s exists-probe and the next `SELECT` both go live). `createTable`-invalidation is uniform +belt-and-suspenders (one line, harmless — invalidating a just-created table only forces the next read +live). **`createDb` is intentionally NOT hooked**: a brand-new database has no table-keyed connector +entries to clear that `dropDb` did not already clear, and Doris routes the db-name-list refresh through +`resetMetaCacheNames` already. Documented, not asked. + +### 1.4 Behavior / cost analysis (this is an INTENTIONAL live change — NOT byte-neutral) +D1 deliberately changes live paimon/iceberg behavior (that is the §3 fix). It is *strictly beneficial and +bounded*: +- **Correctness**: invalidating a dropped/created table's connector entry is always correct — the entry is + either stale (drop) or absent (create). No path reads a "must-stay-pinned" value across a DROP/CREATE. +- **Cost**: one `Cache.invalidate`/`asMap().keySet().removeIf` per DDL — O(1)/O(cache-size), off the query + hot path (DDLs are rare). No new RPC, no force-build (`connector` is already initialized here). +- **No-cache connectors** (jdbc/es and any without caches): `Connector.invalidateTable/invalidateDb` are + no-op SPI defaults → inert. +- **TCCL**: mirrors `RefreshManager`'s existing `getConnector().invalidateTable(...)` call, which pins + nothing — `invalidate*` runs the plugin's own method (no reflection-by-name), so no TCCL pin is needed + (memory `catalog-spi-plugin-tccl-classloader-gotcha` applies to name-reflection, not direct dispatch). +- **hive**: dormant (no `HiveConnector` built pre-flip) — inert until the flip, then armed. + +### 1.5 Tests +- fe-core (`PluginDrivenExternalCatalog` DDL): a fake `Connector` recording `invalidateTable/invalidateDb` + calls; assert `dropTable` (table + view branches) / `createTable` / `dropDb` each invoke it with the + REMOTE db/table names, and `createDb` does NOT. Assert a no-cache connector path is a no-op (default SPI). +- iceberg / paimon (live): after `invalidateTable(db,t)` the next `beginQuerySnapshot` re-pins (drop the + cached `(db,t)` entry). See FIX 1b for the paimon schema-memo half. + +--- + +## 2. FIX 1b — paimon `PaimonSchemaAtMemo` invalidation (completes §3 for paimon) + +### 2.1 The gap +`PaimonConnector.invalidateTable`/`invalidateAll` (`PaimonConnector.java:233/240`) clear only +`latestSnapshotCache`. The second connector-owned cache, `PaimonSchemaAtMemo` (`PaimonSchemaAtMemo.java`, a +plain `ConcurrentHashMap`, key = `(db,table,sysTable,branch,schemaId)`), +has **no invalidate method at all** — cleared only by its `maxSize` valve or a connector rebuild (REFRESH +CATALOG). A drop+recreate that reuses a `schemaId` (e.g. schema 0) with different content yields a stale +time-travel hit even after FIX 1 routes `invalidateTable` to the connector. + +### 2.2 The change +- Add `PaimonSchemaAtMemo.invalidate(String db, String table)` → `cache.keySet().removeIf(k -> + k matches (db,table))` (add a package-private `MemoKey.matches(db,table)` mirroring its equals fields), and + `invalidateAll()` → `cache.clear()`. Pure `ConcurrentHashMap` ops; no framework change. +- Wire `PaimonConnector.invalidateTable` → also `schemaAtMemo.invalidate(dbName, tableName)`; + `invalidateAll` → also `schemaAtMemo.invalidateAll()`. + +### 2.3 Cost / correctness +The memo value is immutable and only *skips* a re-read on a hit; dropping entries only forces a re-read +(the pre-memo behavior) — never a stale/wrong value. The keyspace is tiny; `removeIf` scan is negligible. +Iceberg needs no analog: `IcebergManifestCache` is path-keyed (unique paths, drop+recreate cannot collide) +and its `invalidateAll` (REFRESH CATALOG) already drops it; the `latestSnapshotCache` half is covered by +FIX 1 through `IcebergConnector.invalidateTable` (already clears it, `IcebergConnector.java:412`). + +### 2.4 Tests +paimon unit: populate the memo via `getOrLoad`, call `invalidateTable(db,t)`, assert the `(db,t)` entries +are gone and other-table entries survive; `invalidateAll` clears all. + +--- + +## 3. FIX 2 — per-partition keying of the hive partition-object cache (D2) + +### 3.1 The bug (HEAD-verified) +`CachingHmsClient.partitionsCache` (`CachingHmsClient.java:111`) is +`MetaCacheEntry>`: `PartitionsKey` (`:381-422`) = `(db, table, +requested-name-LIST)` and the value is the WHOLE list as ONE entry. `DEFAULT_PARTITION_CAPACITY=100000` +(`:105`) with a comment claiming "partition objects" parity — but the shared `CacheFactory` has only +`maximumSize`, no weigher (`CacheFactory.java:109`), so 100000 now bounds **distinct request-lists**, each +holding arbitrarily many partition objects (and duplicating them across overlapping lists). Legacy +`HiveExternalMetaCache` keyed ONE partition object per entry (`:121`, cap +`max_hive_partition_cache_num`); **Trino likewise keys per-partition** (`Cache`, flat +`maximumSize`). The list-keyed shape is unique to this cache and under-bounds FE heap. + +### 3.2 The design — value-keyed per-partition entries (matches Trino + legacy; no framework change) +The scan caller (`HiveScanPlanProvider.convertPartitions:332-349`) and every other `getPartitions` caller +(`HiveConnectorMetadata:933/1018/1176/1205`, `HiveWritePlanProvider:257`, `HiveConnectorTransaction:503`) +consume the returned `HmsPartitionInfo` **as a set** — they iterate and read `getValues()`/`getParameters()` +/`getLocation()` and never rely on result order or on a 1:1 name↔result correspondence (the delegate +`get_partitions_by_names` never guaranteed order/cardinality anyway). So: + +- Change `partitionsCache` to `MetaCacheEntry`, `PartitionKey = (db, table, + List values)` — keyed by the partition's OWN values. +- `getPartitions(db, table, partNames)`: + 1. for each requested name, parse it to values (`toPartitionValues`) and `getIfPresent((db,table,values))`; + hits go straight into the result, unparseable/missing names go into a `missNames` list; + 2. if `missNames` non-empty, `delegate.getPartitions(db,table,missNames)` → for each returned info, + `put((db,table, info.getValues()), info)` (keyed by the ACTUAL values — always correct) and add to the + result. +- **Correctness is independent of parse fidelity**: a store always uses the partition's real values; a + lookup misparse simply misses → the name falls to `missNames` → the delegate reloads it → correct result, + only no cache benefit for that (rare, escaped-value) name. Distinct partitions have distinct values, so no + false hit; a requested name with no partition is omitted by the delegate (parity, no negative caching). +- This is the SAME values-keyed correlation `HiveConnectorTransaction:518` already uses + (`partitionsByValues.get(HiveWriteUtils.toPartitionValues(name))`). + +### 3.3 The name→values parser +`HiveWriteUtils.toPartitionValues` (fe-connector-hive) is the byte-faithful port but lives in a module +`fe-connector-hms` cannot import (hms is below hive). Source options at implementation: a small private +helper in `CachingHmsClient` mirroring `HiveWriteUtils.toPartitionValues` (split on `/`, `=`, unescape via +inlined `unescapePathName`), OR `org.apache.hadoop.hive.common.FileUtils` (already a hms-module dependency — +`HmsEventParser` uses `FileUtils.makePartName`). Prefer the FileUtils route to avoid duplicating the +unescape table, unless it complicates the decorator; either is correct (misparse = perf-only). + +### 3.4 What stays the same +- `flush(db,table)` / `flushDb(db)` / `flushAll` (`:164-185`) keep using `invalidateIf(key -> + key.matches(db,table))` / `matchesDb(db)` / `invalidateAll` — `PartitionKey` still carries `(db,table)`, + so the invalidation interface is unchanged (and stays correct under FIX 1's new callers). +- `DEFAULT_PARTITION_CAPACITY=100000` now correctly bounds **100000 partition objects** (legacy semantics); + fix the comment to say so. +- The other three caches (`table`/`partition_names`/`column_stats`) are untouched. +- Dormant: no `HiveConnector`/`CachingHmsClient` is built for a live catalog pre-flip. + +### 3.5 Tests +`CachingHmsClientTest` additions: (a) two overlapping name-lists share per-partition entries (second call +hits, delegate called only for the new names); (b) a requested name with no partition is omitted and not +negative-cached; (c) `flush(db,table)` drops that table's partition entries only; (d) capacity bounds +partition COUNT (put N>cap distinct partitions → size ≤ cap); (e) an escaped-value name still returns the +correct partition (via reload) — no wrong/dropped result. + +--- + +## 4.

It never checks `isLastModifiedFreshness` (unlike `getTableSnapshot` +`:616-635`). Consequence: a hive-backed **SQL dictionary** / **MV auto-refresh** never sees a newer +source version (`Dictionary.hasNewerSourceVersion:271-296` needs a monotone-increasing value) — silent, +no crash.

The hive connector owns a scan-side cache (metastore metadata + directory listing) so that at the + flip, route-collapse to `ENGINE_DEFAULT` is **performance-neutral** vs legacy. +2. `HiveConnector.invalidateTable/invalidateAll` drop that cache (arms `REFRESH TABLE`/`REFRESH CATALOG`). +3. Fix §2.6: flipped `getNewestUpdateVersionOrTime` surfaces a real, cheap max-partition modify time, + cache-backed, restoring SQL-dictionary / MV auto-refresh over hive base tables. +4. Everything lands **dormant** (inert while hms is legacy; byte-neutral for all other connectors). + +### Non-goals (explicitly out of D2 — recorded so they are not silently dropped) +- **Deleting the fe-core caches + the 4 gates + the resolver hms branch.** Per the standing user + decision ("delete legacy last; reach a working flip first"), and because these have **zero live + readers post-flip** (all readers are legacy deletion-unit classes — `HiveScanNode`, `HMSExternalTable`, + `HiveDlaTable`, etc.), deletion rides the **final deletion phase**, not D2. D2 is purely additive; the + fe-core caches simply sit **unrouted** (harmless) after the flip until then. +- **Event-driven incremental invalidation (event Model B — the NEXT task).** Post-flip + `MetastoreEventsProcessor` is `instanceof HMSExternalCatalog`-gated (`:116`) → zero event sync for a + flipped catalog. D2 accepts interim staleness **bounded by TTL + explicit REFRESH**. Model B re-arms + the loop and adds `Connector.invalidatePartitions(db,table,names)`; it **depends on D2's cache**, not + vice-versa (verified: D2 lands first). D2 must **not** attempt partition-granular invalidation. +- **hudi-on-HMS caching regression.** The hudi sibling rebuilds `HoodieTableMetaClient` per query and has + no cache; post-flip it loses caching entirely (correctness fine, perf regression). This is a **separate + hudi-connector item** — but see §3 Option A, which would fix it for free. +- **Column statistics caching.** `getColumnStatistics` is uncached today but gated on `numRows>0` and off + the scan hot-path (planner fast-path only) → defer as a perf item. +- **The two TVF flip-breaks** (`partition_values()` `MetadataGenerator:2091`; `hudi_meta()` `:459`) and + the **`canSample`/`SUPPORTS_SAMPLE_ANALYZE`** stats-gate inconsistency (`AnalysisManager:1484`) — these + are live-SQL flip-survivors, but they belong to the **flip's coupling-seam set** (execution-plan §2.3), + not D2-cache authoring. Recon re-confirmed all three; they are tracked there. + +### Refuted worries (checked against HEAD — do NOT spend budget here) +- **`RefreshManager.refreshPartitions` CCE "blocker"** — REFUTED. **Verified: its sole caller is + `AlterPartitionEvent.java:123`** (event pipeline), which the `instanceof HMSExternalCatalog` event gate + never fires for a flipped catalog. It is Model-B / event-deletion territory, **not a D2 blocker.** + (Two critics initially mis-ranked this as a live-SQL blocker; the caller-trace refutes it.) +- **`CatalogMgr.add/dropExternalPartitions` silent no-op** — REFUTED as D2: callers are all event classes + (`AddPartitionEvent`/`DropPartitionEvent`/`AlterPartitionEvent`) → event-gated → Model B. +- **`replayRefreshTable` partition branch breaks** — REFUTED: post-flip the `instanceof HMSExternalCatalog` + guard is false → falls to `refreshTableInternal` which already fans out `connector.invalidateTable` for + PluginDriven. Graceful coarsening, no crash. +- **Schema cache incoherence at flip** — REFUTED (§1.1). +- **Connector references to fe-core `*ExternalMetaCache` are a layering violation** — REFUTED: + `grep 'import.*ExternalMetaCache'` over `fe-connector/` = zero; all mentions are javadoc. Deletion is + import-clean. +- **`ENGINE_DEFAULT` routing throws at the flip** — REFUTED (§1.1, it's a registered cache). + +--- + +## 3. ARCHITECTURE DECISION — where the metastore-metadata cache lives (needs sign-off) + +Both options put caching **inside the connector** (honoring the LOCKED D2 decision) and both need a +**separate file-listing cache** (§4.4) — Trino keeps these two layers separate too. They differ only in +how the *metastore-metadata* layer is built: + +**Option A — `CachingHmsClient` decorator (Trino `CachingHiveMetastore` style).** A +`CachingHmsClient implements HmsClient` in `fe-connector-hms`, wrapping `ThriftHmsClient`, caching +`getTable` / `listPartitionNames` / `getPartitions` / `getTableColumnStatistics` on +`MetaCacheEntry`s keyed by db/table (values are the connector's own `HmsTableInfo`/`HmsPartitionInfo` +DTOs). `HiveConnector` wraps its client once; `invalidateTable/invalidateAll` delegate to the decorator's +`flush(db,table)/flushAll()`. +- **Pros:** most Trino-faithful; **transparent** to all ~30 `hmsClient.*` call-sites in + `HiveConnectorMetadata` (no cache threading, low error surface); a **reusable class** — the hudi/iceberg + siblings each hold their own `HmsClient` from the same `fe-connector-hms` module (verified + `HudiConnector:68`), so later wrapping their clients with the same decorator **fixes the hudi-on-HMS + caching regression** with zero new machinery. +- **Cons:** caches raw metastore DTOs at RPC granularity (not the higher "resolved partition list" shape); + its own TTL/key config; forks slightly from the paimon/iceberg *shape* (though not the ownership model). + +**Option B — typed cache fields on `HiveConnector` (paimon/iceberg-native shape).** e.g. +`HivePartitionCache` (name+object; value carries max `transient_lastDdlTime` for §2.6) as final fields on +`HiveConnector`, mirroring `PaimonLatestSnapshotCache`; `HiveConnectorMetadata` reads through them. +- **Pros:** matches the existing Doris connector-owned precedent exactly (Rule 11); one obvious home; + aligns 1:1 with iceberg/paimon `invalidateTable/invalidateAll` lifecycle. +- **Cons:** hive-specific (does nothing for the hudi-on-HMS regression); must thread the cache through each + metadata method (more touch-points); caches at result granularity. + +**Recommendation: Option A.** Hive's `HmsClient` is exactly the thin thrift shape Trino decorates (unlike +paimon/iceberg's rich catalog clients), the decorator is transparent over the many call-sites, and its +reusability cleanly retires the hudi-on-HMS regression. It still honors "connector-owned" and keeps the +file-listing cache separate (Trino-aligned). **This is the primary decision for user sign-off (§8-Q1).** + +--- + +## 4. Design (assuming Option A; Option B differs only in §4.3 placement) + +### 4.1 Dependency + packaging (dormant, build-only) +Add `fe-connector-cache` + **Caffeine 2.9.3** to `fe-connector-hive/pom.xml` (paimon pattern — hive +carries no transitive Caffeine). Verify the built plugin zip carries **exactly one** Caffeine 2.9.3 +(memory `catalog-spi-connector-cache-framework-caffeine-coherence`: framework is child-loaded per plugin; +each consumer must self-bundle its lowest-common lib). + +### 4.2 Cache set (minimum viable for scan parity) +1. **Metastore-metadata cache** (Option A: inside `CachingHmsClient`): `getTable` (table meta incl. + `sd`+params → also feeds `getTableHandle`/`getColumnHandles`/`getTableStatistics`), `listPartitionNames` + (pruning), `getPartitions(names)` (per-partition location/inputFormat/**parameters** → also the §2.6 + max-`transient_lastDdlTime` source), `getTableColumnStatistics` (optional; gated, low priority). +2. **File-listing cache** (§4.4): directory `listStatus` results keyed by partition path. +3. **Schema: NOT cached by the connector** — `ENGINE_DEFAULT` covers it (§1.1). Connector `getTableSchema` + is hit only on a schema-cache miss. + +### 4.3 §2.6 — cheap max-partition modify time (dormant fe-core one-liner + connector backing) +- **fe-core** (`PluginDrivenMvccExternalTable.getNewestUpdateVersionOrTime`): add a last-modified branch + mirroring `getTableSnapshot` — when the query pin's `isLastModifiedFreshness()` is set, return + `queryTableFreshness().getTimestampMillis()`; else keep the exact existing path. + **Byte-neutrality constraint (memory `plugindriven-mvcc-table-is-live-not-dormant`):** paimon/iceberg + set `isLastModifiedFreshness()==false` → they keep the current RANGE/`orElse(0L)` path unchanged. The + new branch is dormant until a hive (last-modified) connector exists at the flip. Guard so paimon/iceberg + bytes **and** cost are unchanged. +- **connector**: `getTableFreshness`/`getPartitionFreshnessMillis` read the **D2 metastore-metadata cache** + (cached `getPartitions`), not a live RPC, so the periodic dictionary poll stays cheap. +- **Parity (verified):** legacy `getNewestUpdateVersionOrTime` returns 0 **only for a genuinely empty + partition set**; for an unpartitioned table it builds a partition from table params → table + `transient_lastDdlTime`. The connector's `getTableFreshness` already returns `lastDdlMillis(tableParams)` + for unpartitioned and `0` for empty-partition-set (`:1039-1046`) — **matching legacy**. Confirm at + implementation; if a divergence surfaces, surface it for sign-off (do not silently change behavior). +- **Monotonicity:** `Dictionary.hasNewerSourceVersion` THROWS on a *smaller* value than last seen. Confirm + `transient_lastDdlTime` is non-decreasing across partition rewrites (it is HMS-maintained epoch seconds). + +### 4.4 File-listing cache + TCCL +The directory listing runs plugin-side via Hadoop `FileSystem` reflection. **Adopt the template's +contextual + manual-miss + `autoRefresh=false` pattern** so the loader runs on the **caller (scan) +thread**, which `PluginDrivenScanNode.onPluginClassLoader` already TCCL-pins — the safest choice. If a +dedicated listing executor with background refresh is chosen for perf, **pin TCCL to the connector +classloader inside every loader** (mirror the existing save/set/restore at +`HiveConnectorMetadata:719-727`). This same file-listing cache should also back +`estimateDataSizeByListingFiles` (`:815`) so the periodic `ExternalRowCountCache` row-count refresh for a +no-stats plain-hive table is not an uncached re-listing (critic-confirmed 5th-cache coupling). +> Note: `fsCache` (fe-core `FileSystemCache`) is NOT part of D2 — the connector uses Hadoop's native +> `FileSystem` cache (scheme+authority+UGI keyed). Confirm `doAs`/UGI keying doesn't defeat it. + +### 4.5 Invalidation scope (coarse only) +- Override `HiveConnector.invalidateTable(db,table)` (drop that table's metastore + file entries) and + `invalidateAll()` (clear all). fe-core wiring already exists (§1.4) — no fe-core change. +- **REFRESH DB gap:** only `invalidateTable`+`invalidateAll` reach the connector; `REFRESH DB` on a + flipped catalog won't drop per-table entries for that db. **Recommendation: accept per-table/all + coverage** for D2 (REFRESH CATALOG covers it; a db-level verb is Model-B-adjacent). Documented, not asked. +- Partition-granular invalidation + event re-arming = **Model B**, out of scope. + +### 4.6 Dormancy proof +- `"hms"` is absent from `SPI_READY_TYPES` (`CatalogFactory:55-56`) → **no `HiveConnector` is built for + hms** until the flip; the cache fields/decorator exist but are never instantiated for a live catalog. +- `invalidateTable/invalidateAll` overrides fire only for a `PluginDrivenExternalCatalog` holding a + `HiveConnector` — none exist for hms pre-flip. +- The §2.6 fe-core branch only executes for `isLastModifiedFreshness()==true` — no live connector sets it. +- ⇒ Every sub-step is byte-neutral for paimon/iceberg/jdbc/doris and inert for hms until the flip. + +--- + +## 5.

Two weeks of work went entirely into the **hudi delegation line** (HD-A0 … HD-D1 + the arming pivot HD-B2), so **all connector-side dormant steps are now DONE**. But the plan's §5 assumed two large **fe-core** subsystems (event-pipeline relocation + connector-owned cache) would also land dormant before the flip. **They were never started (0% at HEAD).** + +**⇒ The flip is NOT executable as one commit today.** The atomic flip commit *neutralizes* four gates (the HMS event poller + three cache-routing sites). Those gates going false is only *safe* if their replacements already exist. They don't.

The blocker (verified) +After the flip, `HiveConnector` gets a `DefaultConnectorContext` whose `executeAuthenticated` = `authSupplier.get().execute(task)` with `authSupplier = () -> NOOP_AUTH` (2-arg ctor, `DefaultConnectorContext.java:100-101,164-166`; `NOOP_AUTH.execute` runs `task.call()` directly). The HMS metastore RPC runs via `ThriftHmsClient` whose `authAction = context::executeAuthenticated` (`HiveConnector.java:105`) → **SIMPLE auth for a Kerberos HMS = silent security downgrade.** + +## 2. The fix (settled design — do NOT use iceberg's full context wrapper) +Substitute **only the `AuthAction`** given to `ThriftHmsClient` with a plugin-side Kerberos `doAs`; do **not** wrap the whole `ConnectorContext` in a plugin-loader-pinning `TcclPinningConnectorContext` (iceberg's approach). Reason: `ThriftHmsClient.doAs` (`ThriftHmsClient.java:529-538`) deliberately pins the RPC's TCCL to `ClassLoader.getSystemClassLoader()`; iceberg's wrapper would re-pin to the plugin loader inside `executeAuthenticated` and override it. hadoop + fe-kerberos are bundled **child-first** in the hive plugin (parent-first prefixes are only `org.apache.doris.connector.`/`.filesystem.`), so the plugin's `HadoopAuthenticator` and the plugin's `ThriftHmsClient` RPC share the SAME (plugin) UGI copy — the `doAs` correctly wraps the RPC with **zero** TCCL change. + +Two verified corrections to the naive draft: +- `AuthAction.execute` is a **generic** method (` T execute(Callable)`) → a lambda cannot implement it (JLS 15.27.3, which is why the existing code uses a method reference).

Options: +- **(a) depend on `fe-connector-metastore-iceberg`** (subagent default) — zero new code, reuses the canonical parser, but bundles an **iceberg-named** module (and its rest/glue/dlf/jdbc providers) into the **hive** plugin: a dependency-inversion smell at the foundation of the hive migration. +- **(b) depend on `fe-connector-metastore-paimon`** — same smell, different flavor. +- **(c) create a neutral `fe-connector-metastore-hms`** module (extract the HMS provider + `HmsMetaStoreProperties`; iceberg/paimon can later dedup onto it) — cleanest long-term, reused by ALL hive read-SPI, but new-module scope now. +- **(d) build the authenticator inside `fe-connector-hms`** (reuse its existing `HmsClientConfig`/`HmsConfHelper` HiveConf + add `fe-kerberos`), hand-reproducing the small legacy key logic — HMS-native, minimal deps, but bypasses the centralized metastore-spi parser (a minor inconsistency with the established "meta parsing via metastore-spi" pattern). + +This choice is reused by the entire hive read-SPI (design §4.2), so it must be settled deliberately, not defaulted. + +## 4.

Residual risks (Rule 12) +- Cannot fully verify without a live KDC — unit tests assert built/not-built only; the real `loginUserFromKeytab` + doAs-wraps-RPC (and that the child-first plugin UGI copy is the one the RPC uses) needs a Kerberized-HMS redeploy smoke (the design's R-002 gate). +- Write-path HDFS Kerberos (`HiveWritePlanProvider`/committer use `context.executeAuthenticated` directly) is NOT covered by this commit — it still resolves to NOOP. It is dormant (P7.3) + full-ACID write is hard-rejected; insert-only write to Kerberos HDFS auth is a follow-up at the write cutover (wrap the write-path context there, where a plugin-loader TCCL pin is appropriate — no ThriftHmsClient SYSTEM-pin conflict on that path). +- Case-sensitivity of the storage-auth value + hive-site.xml-only krb settings not folded into the login conf — both mirror iceberg's existing behavior. diff --git a/plan-doc/tasks/hms-cutover-retype-design-2026-07-07.md b/plan-doc/tasks/hms-cutover-retype-design-2026-07-07.md new file mode 100644 index 00000000000000..99745c16b0dda7 --- /dev/null +++ b/plan-doc/tasks/hms-cutover-retype-design-2026-07-07.md @@ -0,0 +1,131 @@ +# HMS cutover — catalog/table retype design (2026-07-07) + +> Produced by a code-grounded recon (`wf_e0586006-60f`: 8 dimension readers + 2 critics — completeness + ordering/risk) with lead-engineer HEAD verification of the load-bearing facts.

The shape of the work: dormant preconditions → one atomic flip → mechanical delete + +The **ordering critic verdict** (confirmed against HEAD + paimon/iceberg precedent): the retype is **necessarily one atomic, catalog-wide switch**. It cannot be staged per-table or per-dimension, because dispatch is by **class identity** (`instanceof PluginDrivenExternalCatalog/Table`), not a runtime toggle. The moment `"hms"` enters `SPI_READY_TYPES` and the GSON tags remap, **every** hms catalog/db/table retypes at once across scan/write/DDL/stats/MVCC/GSON/event-poller/cache-routing. + +Three regimes: + +### (A) DORMANT — build ahead of the flip, zero user-visible effect +`CatalogFactory.java:103` never routes `hms` through the plugin path until `"hms"` is in `SPI_READY_TYPES`, so all connector-side scaffolding lands dormant (proven by P7.1 DDL / P7.3 write+ACID / P7.4 scan-seam). Everything in §4 is built here. + +### (B) THE FLIP — one atomic commit (the "must-be-atomic set") +1. **3 GSON tag remaps** — delete `registerSubtype` + add `registerCompatibleSubtype` for catalog (`GsonUtils.java:366`), db (`:447`), table (`:471`). *These are mutually locked:* you cannot add the compat mapping without first deleting the `registerSubtype` (else `RuntimeTypeAdapterFactory:279` throws "labels must be unique" at static-init → FE won't boot); but deleting `registerSubtype` also kills the **write** registration, which crashes image-write for any live `HMSExternalCatalog` — and `CatalogFactory:134` keeps building those until `"hms"` is in `SPI_READY_TYPES`. **⇒ GSON remap and the SPI_READY flip must ship in the same commit** (a standalone "GSON-first" PR is impossible; paimon `a26eaeff84c` did exactly this in one commit). +2. `SPI_READY_TYPES += "hms"` (`CatalogFactory.java:49-50`) + delete the dead `case "hms"` fallback (`:133-135`). +3. `buildDbForInit` `case HMS` → `new PluginDrivenExternalDatabase` (`ExternalCatalog.java:966-968`, mirror the ICEBERG case). +4. Remove the now-dead `PhysicalPlanTranslator` HMS arms (`:818-846` scan, `:925-928` hudi) + the `DLAType` import (`:65`) — they become unreachable (the `:808` PluginDriven arm wins) but still compile-reference the legacy scan nodes, blocking their deletion. +5. Neutralize the **event-poller gate** (`MetastoreEventsProcessor:116`) and **cache-routing gates** (`ExternalMetaCacheRouteResolver:66`, `HiveExternalMetaCache:203/274`, `IcebergExternalMetaCache:234`) — all four go `false` at the flip **simultaneously and silently** (no crash, no log). Event sync would halt and cache-routing collapse to `ENGINE_DEFAULT` unless handled in the atomic set (or the flip is gated until §4's event/cache work lands). *This is the strongest proof the flip is atomic.* +6.

GSON single-row MVCC does **not** force a squash: `registerCompatibleSubtype` takes a label **string**, which survives class deletion. + +--- + +## 3. The heterogeneity crux + the GSON single-row conflict (the central correctness problem) + +One HMS catalog mixes non-MVCC plain-hive + MVCC iceberg/hudi-on-HMS, today carried by **one class** `HMSExternalTable` that implements `MvccTable`/`MTMVRelatedTableIf` for **every** `dlaType`, branching at runtime on a **lazily-probed, non-persisted** `dlaType`. Two independent facts force the **same** answer: + +- **GSON:** the persisted `clazz` tag is uniformly `"HMSExternalTable"` (dlaType is transient — excluded by `HiddenAnnotationExclusionStrategy`, never in the JSON), so `registerCompatibleSubtype` can only map that **one label → one class**. Content-based dispatch is impossible in one release (no persisted discriminator). +- **buildTableInternal:** selects base-vs-Mvcc from the **catalog-level** `SUPPORTS_MVCC_SNAPSHOT` capability (`PluginDrivenExternalDatabase.java:53`), uniform for all tables in the catalog. + +**⇒ Decision (evidence-forced, matches paimon/iceberg precedent at `GsonUtils:490/494`):** map `"HMSExternalTable"` → **`PluginDrivenMvccExternalTable`** AND have the hive gateway declare `SUPPORTS_MVCC_SNAPSHOT`; resolve hive/hudi/iceberg heterogeneity **at runtime inside the connector by table handle** (hive-handle path degrades MVCC to an empty pin; iceberg-handle delegates to the sibling). The GSON read-target and what `buildTableInternal` builds live **must agree** for round-trip consistency. The safety of the single base-tag mapping rests on the verified invariant that **deserialized external-table objects never survive a replay** (metaCache transient, `initialized` reset to false, tables rebuilt live via `buildTableInternal`, MTMV/BaseTableInfo use id-refs) — pinned by `HmsGsonCompatReplayTest`. + +**Consequence to handle (MAJOR):** plain-hive now uses the Mvcc subclass, whose `loadSnapshot(empty,empty)` calls `materializeLatest()` (eager partition listing) vs the legacy `EmptyMvccSnapshot` (lazy). Mitigation: the hive gateway's `beginQuerySnapshot` returns empty for hive handles → empty pin → hive partition reads stay on the normal `listPartitions` path. And `getTableSnapshot` must become **freshness-kind-aware** (see §4 blocker) or MTMV over a hive base table never detects changes. + +--- + +## 4. Dormant precondition build-out (regime A) — the real work + +Ordered by the phase plan in §5. Blockers marked ⛔. + +### 4.1 Connector auth + property parity (fe-connector-hive) +- ⛔ **Kerberos authenticator.** Today `HiveMetadataOps:73` builds its thrift client with `catalog.getExecutionAuthenticator()` — a **real** authenticator set by `HMSExternalCatalog.initPreExecutionAuthenticator:129`. `PluginDrivenExternalCatalog` deliberately does **not** override it (base no-op), and `HiveConnector:105` uses the raw `context::executeAuthenticated` — unlike `IcebergConnector` it neither builds a plugin-side authenticator nor wraps the context in `TcclPinningConnectorContext` (contrast `IcebergConnector:162-177,783-821`). **Secured HMS would silently degrade to SIMPLE auth.** Fix: give `HiveConnector` the iceberg treatment (lazy plugin-side `HadoopAuthenticator` + `TcclPinningConnectorContext`). **Gate: a Kerberos-HMS smoke test.** +- **Property parity moves connector-side** (fe-core stays property-agnostic): TTL range checks (`file.meta.cache.ttl-second` / `partition.cache.ttl-second`, `checkProperties:108`) → hms `ConnectorFactory.validateProperties`; the `ipc.client.fallback-to-simple-auth-allowed` default (`setDefaultPropsIfMissing:234`) → `HiveConnector.deriveStorageProperties`. Regression tests for both TTL error messages + mixed kerberos/simple auth. + +### 4.2 Connector read-side SPI (fe-connector-hive is still a read-mostly skeleton) +- ✅ **`partition_columns` emission — DONE (`32b9526f689`, dormant).** `HiveConnectorMetadata.getTableSchema` did not mark which emitted columns are partition columns → `toSchemaCacheValue` derived **empty** partition columns → every partitioned hive/hudi table read as **unpartitioned** (wrong pruning/count, MTMV breakage). Fix landed = emit the cross-connector **`partition_columns` CSV-of-raw-names table-property** (the *unanimous* mechanism — verified emitted by paimon `PaimonConnectorMetadata:313`, iceberg `IcebergConnectorMetadata:443`, maxcompute `MaxComputeConnectorMetadata:163`; the design's earlier "add a first-class `partitionColumnNames` field, preferred over the string-property hack" was **wrong** — the property is the established convention and hive partition-key names are comma-free identifiers, so the field would only fork a working SPI). Connector also widens a `string` partition column to **`varchar(65533)`** — the exact `ScalarType.MAX_VARCHAR_LENGTH`, **not 65535** (the "65535" in this doc AND in the legacy `HMSExternalTable.java:835` comment are both stale; the constant is 65533) — replicating legacy `initPartitionColumns` (only `PrimitiveType.STRING` is coerced; non-string partition cols and plain string DATA cols keep their mapped types). +- ⛔ **Missing SPI methods:** `listPartitions` (real per-partition `lastModifiedMillis`), `getTableStatistics` (HMS-param rowCount + file-list estimate fallback + dataSize), `buildTableDescriptor` (`THiveTable`/`TTableType.HIVE_TABLE`), `listSupportedSysTables`, `viewExists`/`getViewDefinition` (Presto-view base64 parsing), and `getCapabilities`. Without these, `getNameToPartitionItems`/`fetchRowCount`/`toThrift`/`$partitions`/hive-views all degrade to empty on a flipped table. +- **`getCapabilities`** must declare `SUPPORTS_MVCC_SNAPSHOT` + the per-table caps the legacy `dlaType` gates imply. **⚠ Over-eligibility risk (completeness critic):** `SUPPORTS_TOPN_LAZY_MATERIALIZE` and `SUPPORTS_NESTED_COLUMN_PRUNE` are per-table **file-format** gated in legacy (orc/parquet only, views/hudi excluded); as catalog-wide flags they'd make text/json/csv/view/hudi tables over-eligible (nested prune on non-parquet can read NULL leaves). **⇒ these two need a per-handle format gate, not a blanket capability.** +- **Fail-loud parity:** `HiveTableFormatDetector.detect` returns `UNKNOWN` silently where legacy `supportedHiveTable()` throws `NotSupportedException` ("Unsupported hive input format"). Connector must fail loud in `getTableHandle`/`getTableSchema` (message aligned to connector wording). +- **Read file-format serde nuance (completeness critic):** legacy `getFileFormatType(SessionVariable)` has a `read_hive_json_in_one_column` session-var branch (+ a first-column-string `UserException`) and a `FORMAT_TEXT` vs `FORMAT_CSV_PLAIN` distinction the connector's `HiveFileFormat.detect`+`mapFileFormatType` collapses. Decide: reproduce (needs a session-var surface on `ConnectorSession`) or accept the behavior change (document). + +### 4.3 Connector MVCC / MTMV / sys-table SPI +- ⛔ **`getTableSnapshot` freshness-kind-aware.** `PluginDrivenMvccExternalTable.getTableSnapshot` hardcodes `MTMVSnapshotIdSnapshot(snapshotId)`; for a plain-hive empty pin (`-1`) this is a **constant** → MTMV over a hive base table never detects change (**stale MV**). Fix: branch like `getPartitionSnapshot` — when the connector's freshness is `LAST_MODIFIED` (hive), emit a timestamp snapshot (`MTMVTimestampSnapshot` partitioned; `MTMVMaxTimestampSnapshot`-equivalent from a connector-supplied table-level lastDdlTime unpartitioned). Requires the connector to surface table last-DDL/modified time. +- **Sys tables:** iceberg-on-HMS `$snapshots` already throws today (`IcebergSysTable.createSysExternalTable`) → the connector-driven native path is a net improvement. Hive `$partitions` is a legacy **TVF** (`PartitionsSysTable`) — the fe-core resolver supports both native + TVF; decide keep-TVF-routed vs expose-native. + +### 4.4 Cross-plugin sibling-connector SPI (iceberg-on-HMS delegation) +- ⛔ **`ConnectorContext.createSiblingConnector(String type, Map props)`** (0 hits today). Default: `throw UnsupportedOperationException` (non-gateway connectors unaffected). Implement in `DefaultConnectorContext` (same fe-core pkg as `ConnectorFactory`) over `ConnectorFactory.createConnector(type, props, this)` → builds a real `IcebergConnector` in the **iceberg plugin's own child-first classloader** (co-packaging iceberg into the hive zip is rejected — 2nd AWS SDK poisons S3). All three TCCL pin loci are then covered **for free** because the sibling is a real `IcebergConnector` (scan-thread auto-pin via provider classloader; write/DDL via the sibling's own `TcclPinningConnectorContext`; worker pool via `pinIcebergWorkerPoolToPluginClassLoader`). +- **Property synthesis (plugin-side):** gateway injects `iceberg.catalog.type=hms` (`IcebergConnectorProperties.TYPE_HMS`) + shares hms metastore/storage/kerberos props before building the sibling. +- **Gateway-owned wrapper handle** (`HmsGatewayTableHandle{ HiveTableType format; ConnectorTableHandle delegate }`): the gateway (hive loader) must **never** `instanceof`/cast the foreign `IcebergTableHandle` (iceberg loader). All dispatch branches on the gateway-owned format enum (same loader) and passes the unwrapped delegate to the sibling. +- **Per-table metadata + write/procedure delegation** (seam A is scan-only): the gateway's `ConnectorMetadata` delegates `getTableHandle`/schema/MVCC internally keyed on `HiveTableFormatDetector` (no new engine seam). For write/procedure (which carry no handle today): add default handle-aware overloads `getWritePlanProvider(handle)`/`getProcedureOps(handle)` mirroring seam A (recommended for symmetry), or a gateway dispatching provider. + +### 4.5 Write-chain + read-txn rewire +- The plain-hive **write** path is already class-forked (`UnboundTableSinkCreator`/`BindSink`/`PhysicalPlanTranslator`), so the retype makes it fall through to the live `UnboundConnectorTableSink → PluginDrivenTableSink → PluginDrivenInsertExecutor` driven by the dormant `HiveWritePlanProvider`/`HiveConnectorTransaction` — no new fe-core branches. The whole legacy sink chain becomes deletable. +- ⛔ **Read-ACID query-finish commit is unwired plugin-side.** `HiveScanPlanProvider.planAcidScan` registers a `HiveReadTransaction` (read lock + write-id snapshot) but nothing deregisters/commits it. Fix (fe-core-driven, keeps `ConnectorSession` free of query lifecycle): when the plan provider opens a read txn, `PluginDrivenScanNode` registers a `QueryFinishCallbackRegistry` callback → new `ConnectorScanPlanProvider.releaseReadTransaction(queryId)` → `HiveReadTransactionManager.deregister` (mirrors how `PluginDrivenInsertExecutor` drives the write commit). +- **Two hive write pre-checks** (`BindSink`: reject explicit-partition-spec INSERT `:668`; reject LZO read-only `:678`) → push into the hive connector write path (fail-loud), keeping fe-core connector-agnostic. +- **Env-held read txn mgr** (`Env.hiveTransactionMgr` + accessors `:568/865/1097/1101`) → delete at the read cutover once legacy `HiveScanNode` (its only caller) is deleted; the plugin `HiveReadTransactionManager` owns it per connector. +- **`BIND_BROKER_NAME`** constant (`HMSExternalCatalog:60`, referenced by `ExternalCatalog.bindBrokerName():1320`) → relocate to `BrokerProperties.BIND_BROKER_NAME_KEY` (already the identical `broker.name` key); drop the HMS copy. +- **`pluginCatalogTypeToEngine`** (`CreateTableInfo`) has no `"hms"` entry → returns null → no-ENGINE CREATE TABLE throws. Add `case "hms": return ENGINE_HIVE;`. + +### 4.6 Coupling-site neutralization (65 sites; NONE need an `if(format)` to survive) +Every `instanceof HMSExternal*` goes false at the flip and the PluginDriven arm already beside most sites takes over. Residual sites needing a **connector capability/SPI** (not a branch): `canSample`/`isSamplingPartition` (add `SUPPORTS_SAMPLE_ANALYZE`); `partition_values()` TVF (add PluginDriven to the gate + `MetadataGenerator` case); SQL-cache version tracking (generalize the type gate to plugin tables with `getUpdateTime()`); partition-level cache invalidation (add `Connector.invalidatePartition(s)` — pairs with the event pipeline); hive-view config gate (`enable_query_iceberg_views` is iceberg-specific — carry the view-enable/dialect per-connector); SHOW PARTITIONS / SHOW CREATE (connector partition-list / show-create SPI or accept generic rendering). Full list + file:line in the recon output `couplingSites`. + +### 4.7 Event pipeline relocation (Model B — flip-gated) +Covered by `hms-event-pipeline-findings-2026-07-07.md`. Thin fe-core role-aware `MasterDaemon` driver + plugin `pollOnce` SPI returning neutral change-descriptors (must cover register/unregister/rename + partition-NAME granularity). fe-core wraps `pollOnce` in an `onPluginClassLoader` pin (R-010). The one poller gate (`MetastoreEventsProcessor:116`) is part of the atomic flip set. `ExternalMetaIdMgr` can be dropped for HMS (ids name-derived) but opcode `470` + a neutral replay handler must survive on-disk (replay-CCE fix already landed `a6dc782d816`). + +--- + +## 5.

Decisions — LOCKED (user sign-off 2026-07-07) + +- **D1 — Hive metadata statistics fast-path → PRESERVE via new SPI (option b).** Add a `ConnectorStatisticsOps.getColumnStatistics(session, handle, colName)` SPI returning a neutral column-stat DTO (count/ndv/numNulls/dataSize/avgSize) + a `PluginDrivenExternalTable.getColumnStatistic` override. The hive connector ports `getHiveColumnStats`/`setStatData` (no-scan HMS/spark col-stats, query-planning fast path, `enable_fetch_iceberg_stats`-gated for the iceberg sibling); the iceberg connector ports `getIcebergColumnStats`. Table-level rowCount stays via `getTableStatistics` regardless. *(Chosen over dropping-for-parity: the no-ANALYZE fast path is kept high-value for hive.)* **⇒ this pulls the per-column stats SPI into the regime-A build-out (§4.2a).** +- **D2 — Cache ownership → CONNECTOR-OWNED (option a).** Retire the fe-core `HiveExternalMetaCache`/hudi/iceberg-on-hms meta caches; the connector owns scan-side caching (paimon/iceberg-native precedent). Delete the route/loader `instanceof HMSExternalCatalog` sites (`ExternalMetaCacheRouteResolver:66`, `HiveExternalMetaCache:203/274`, `IcebergExternalMetaCache:234`) + the partition-cache-inconsistency self-heal moves connector-side (or is dropped — decide at implementation). This is the largest catalog-adjacent structural item; it lands with the flip set. +- **D3 — Iceberg-on-HMS delivery → BUILD SIBLING SPI BEFORE THE FLIP (option a), no regression.** The cross-plugin sibling-connector SPI (§4.4) is a hard precondition and must land dormant before the flip so existing iceberg-on-HMS tables keep working. If it slips, the flip slips (no fail-loud-reject regression). +- **D4 — PR shape (decide at flip time).** two-PR split (paimon: revertable flip + mechanical delete) vs one squash (iceberg). **Leaning two-PR;** confirm at the flip. +- **D5 — External-view query-time enable gate → DROP entirely, Trino-aligned (user sign-off 2026-07-07).** At the flip, the `BindRelation` plugin-view arm (`:634`) stops gating on `Config.enable_query_iceberg_views` (and the dead HMS arm's `enable_query_hive_views` at `:594` goes away with the arm): an external view is served whenever `isView()` — no per-connector query-time toggle (Trino has none; the two Doris flags were legacy safety valves). Both `enable_query_hive_views` / `enable_query_iceberg_views` become deprecated no-ops (keep the `@ConfField` for one release to avoid "unknown config" on upgrade; remove later). Also neutralize the iceberg-worded time-travel rejection message + the stale `:626-632` invariant comment. **Consequence to bundle deliberately:** this ungates *iceberg* views too, which are already live behind `enable_query_iceberg_views` — so D5 is a **visible iceberg behavior change** and must ship with (or as a deliberate part of) the flip, not leak in early. Satisfies the iron rule with **no** `if(engine)`/OR-of-two-flags. +- **D6 — SHOW CREATE VIEW output → accept the plugin path's decoded form (user sign-off 2026-07-07).** Post-flip a hive view's SHOW CREATE renders the generic `CREATE VIEW AS ` where `getViewText()` is the **Presto/Trino-decoded** SQL (legacy HMS `HiveMetaStoreClientHelper.showCreateTable` emitted the **raw encoded** `/* Presto View: */`). The decoded form is more readable and is the accepted output; any hive-view SHOW CREATE regression baseline that pinned the raw-encoded bytes is updated to the decoded text at the flip. + +### §4.2a — Per-column statistics SPI (from D1=preserve) +- Add `ConnectorStatisticsOps.getColumnStatistics(session, handle, colName)` → neutral column-stat DTO. `PluginDrivenExternalTable.getColumnStatistic` override consults it (query-planning cache-miss fast path). Hive connector ports the HMS/spark col-stats read (incl. partition-level col stats `getHivePartitionColumnStats` for the ANALYZE metadata path); iceberg connector ports `getIcebergColumnStats` behind `enable_fetch_iceberg_stats`. This also gives `HMSAnalysisTask`'s metadata fast path a home (revisit whether `ExternalAnalysisTask` consults the new SPI vs SQL-only FULL analyze — the DTO makes preserving the metadata path feasible). + +--- + +## 7.

What §4.4 delivers (recap) + +A flipped `hms` catalog is served by the **hive plugin as a GATEWAY**; its iceberg-on-HMS (and, later, hudi-on-HMS) tables are delegated to a **sibling connector built in the iceberg plugin's own child-first classloader**. Co-packaging iceberg into the hive zip is REJECTED (2nd AWS SDK poisons S3 JVM-wide — iceberg pom RC-3 comment). Cross-plugin objects share only the **parent-first SPI interfaces** (`org.apache.doris.connector.*` / `.filesystem.*`); any concrete iceberg type crossing into the hive loader CCEs. + +**Dormancy anchor (hard constraint):** the entire gateway surface is dead until `"hms"` enters `SPI_READY_TYPES` (today `{jdbc,es,trino-connector,max_compute,paimon,iceberg}`, `CatalogFactory.java:49-50`) — that single line is THE flip. **No dormant sub-step may touch `SPI_READY_TYPES`.** + +## 2. The discriminator decision — CORRECTS design §4.4 (evidence-forced) + +Design §4.4 proposed a gateway-owned **wrapper handle** `{HiveTableType format; ConnectorTableHandle delegate}`. **This is dead.** `PluginDrivenScanNode.resolveScanProvider` selects the provider via `connector.getScanPlanProvider(currentHandle)` (`:209`) and then threads the **same** `currentHandle` object into `scanProvider.planScan(...)` (`:966`); `IcebergScanPlanProvider` unconditionally casts `(IcebergTableHandle) handle` (`:319/:364/:468/:1009`). There is **no engine unwrap seam** between selection and invocation — so a wrapper handed in for selection is byte-identically what iceberg then casts → CCE. + +**⇒ Decision (the S3/S4/S5 contract):** `getTableHandle` for an ICEBERG table returns the **raw foreign iceberg handle** (the iceberg connector's own `getTableHandle` output) so iceberg's cast succeeds; every gateway consumer discriminates by **`instanceof HiveTableHandle` (the gateway's OWN hive-loader type) → hive path, else → forward to sibling**. The gateway **never** `instanceof`/casts the foreign iceberg handle. Needs **no new SPI** (no format-tag interface, no handle-identity map). `ConnectorTableHandle` is a bare marker (`interface … extends Serializable {}`, zero methods), consistent with the iron rule (fe-core never reads format). + +## 3. Ordered dormant sub-steps (each an independent休眠 commit) + +- **S0 — fe-core sibling seam `createSiblingConnector` ✅ DONE (this session).** `ConnectorContext.createSiblingConnector(String catalogType, Map properties)` default `return null` (matches every other SPI default's safe-default convention — NOT throw, correcting the design's "UnsupportedOperationException"); `DefaultConnectorContext` override = `return ConnectorFactory.createConnector(catalogType, properties, this)` (passes `this` → sibling shares catalogId/auth/storage suppliers; the sibling's HMS-flavor `HiveCatalog` name defaults to `context.getCatalogName()`, so the shared context is load-bearing). Only fe-core change in the whole feature; hard prerequisite for all plugin work (the hive plugin holds only the `ConnectorContext` interface, so this seam is its ONLY way to build a sibling that inherits the hms catalog's context, and keeps the plugin off `ConnectorFactory` statics). +- **S1 — hive-loader props-synthesis helper (pure) ✅ DONE (`d971410af62`).** `IcebergSiblingProperties.synthesize(gatewayCatalogProps)` (per-catalog — the sibling is table-agnostic, NO `HmsTableInfo` needed) = **copy the gateway catalog's whole property map verbatim + inject literal `iceberg.catalog.type=hms`** (hardcoded strings; `IcebergConnectorProperties.TYPE_HMS`/`ICEBERG_CATALOG_TYPE` are child-first, invisible to the hive loader). **Copy-all (not a hand-picked subset)** is the robust + verified choice: it is the EXACT map shape the iceberg connector already handles for a native `type=iceberg, iceberg.catalog.type=hms` catalog (fe-core's `createConnectorFromProperties` passes the full catalog props), and iceberg's `create()` does NO property validation, so hive-only delta keys are ignored not misused — **adversarially verified** (every delta key ignored; `warehouse` harmless because the HMS flavor never derives `fs.defaultFS` from it and existing tables use their stored locations; one non-defect note = the sibling uses iceberg's default cache TTL, same as native iceberg-on-hms). Never mutates the input; overrides any stray flavor. Minimum working props for hms-flavor: `{iceberg.catalog.type=hms, hive.metastore.uris|uri}`; `warehouse` NOT required. Independent of S0. Full green (4 tests + checkstyle + import gate). +- **S2 — embedded-sibling holder + lazy build + close-forward.** `HiveConnector`: memoized `volatile Connector icebergSibling` = `context.createSiblingConnector("iceberg", S1.synthesize(...))`; forward `close()` to it then null. **Must be ONE sibling per gateway connector** (not per-table): `IcebergConnector` holds per-catalog caches (`latestSnapshotCache`, `manifestCache`, scan→write `rewritableDeleteStash`) shared across its tables — a per-op sibling would fragment them. Held ONLY as the parent-first `Connector` type — never cast. Deps: S0, S1. +- **S3 — metadata handle-guard-and-forward.** `HiveConnectorMetadata` every handle-based method: `if (!(handle instanceof HiveTableHandle)) return sibling.getMetadata(session).(…); `. The delegation surface is **two disjoint sets**: (a) override-and-divert the hive-implemented mis-servers (`getTableSchema[+snapshot]`, `getColumnHandles`, `getTableStatistics`, `listPartitions/Names/Values`, `beginQuerySnapshot`, `getTableFreshness`, `getPartitionFreshnessMillis`, `buildTableDescriptor`, `applyFilter`, DDL); (b) forward the wholesale-**absent** iceberg subset that today silently no-ops (`getMvccPartitionView`, `resolveTimeTravel`, `applySnapshot`, `applyRewriteFileScope`, `applyTopnLazyMaterialization`, `applyProjection`, `applyLimit`, `listSupportedSysTables`, `getSysTableHandle`, schema-at-snapshot) — several are **silent wrong answers**, not fail-loud, so a partial gateway ships silent MVCC/time-travel corruption. **`beginQuerySnapshot` must divert together with freshness** (its `isLastModifiedFreshness=true` flag gates whether `getTableFreshness` is even consulted). The handle-in/handle-out `apply*` must forward AND return the sibling's handle **unmodified** (a single un-rewrapped return poisons a downstream `planScan` cast). Deps: S2. +- **S4 — `getTableHandle` ICEBERG divert.** When `HiveTableFormatDetector.detect(...)==ICEBERG`, return the sibling's `getTableHandle` (foreign iceberg handle) instead of a HiveTableHandle stamped ICEBERG. The pivot that lights up S3 + makes iceberg's cast succeed. HUDI stays fail-loud/legacy. Deps: S3 (keep adjacent), S2. +- **S5 — scan-provider gateway override.** `HiveConnector.getScanPlanProvider(ConnectorTableHandle handle)`: `if (handle instanceof HiveTableHandle) return getScanPlanProvider(); return sibling.getScanPlanProvider(handle);`. Loader-safe negative test on the gateway's own type. Returned provider is iceberg-loader-built → scan-side TCCL auto-pins for free (`PluginDrivenScanNode.onPluginClassLoader` keys off `provider.getClass().getClassLoader()`). Deps: S2 (pairs with S4). +- **S6 — name-based + connector-wide residuals divert (thin).** Name-based methods (no handle: view methods, `buildTableDescriptor`) re-run `HiveTableFormatDetector.detect(db,table)` and forward for ICEBERG. Per-handle capability gating is NOT expressible on the connector-wide `getCapabilities` — leave documented residual for the flip (do not over-build). Deps: S2, S4. + +## 4. TCCL / classloader facts (verified) + +- **Scan pin #1** (`PluginDrivenScanNode.onPluginClassLoader`, `:516-524`): connector-agnostic, keys off `provider.getClass().getClassLoader()` → a sibling iceberg scan provider **auto-pins for free**. +- **Write/DDL pin #2** + **worker-pool pin #3**: baked INTO `IcebergConnector` (ctor wraps context in `TcclPinningConnectorContext`; `pinIcebergWorkerPoolToPluginClassLoader` once-per-JVM), keyed off `getClass().getClassLoader()`=iceberg loader → **free** for any sibling built via the factory. +- **Metadata `apply*` are NOT wrapped** in `onPluginClassLoader` (bare on the query thread's app TCCL) — BUT this is **pre-existing, not new**: `PluginDrivenExternalTable` has ZERO pins and the already-live direct iceberg SPI catalog runs the identical `IcebergConnectorMetadata` on app TCCL, relying on iceberg's own `executeAuthenticated` pins. The sibling reuses that identical metadata → inherits identical coverage. Down-graded from "risk" to "unchanged". (S3 may add a cheap gateway-side pin `sibling.getClass().getClassLoader()` around forwarded metadata as belt-and-suspenders; validate at flip.) + +## 5. Not dormant-testable → thin scaffolding + flip-time e2e gate ONLY + +1. **The CCE boundary is invisible to same-loader unit tests** — fe-core/fe-connector test classpaths can't load iceberg's child-first classes; recording fakes are app-loader types, so an illegal foreign-handle cast **passes** in unit tests. Options: build ONE small `URLClassLoader` two-loader test fixture reused across S3/S5, OR accept a flip-time redeploy classloader smoke. Budget an integration check. +2. **Real HMS→iceberg catalog build + parity** (storage/kerberos overlay, manifest cache + profile counters, count-pushdown-from-snapshot, delete-file/deletion-vector thrift, worker-pool pin, AWS-SDK isolation) — live HMS + iceberg table only.

The sibling is **always** the hms flavor (`IcebergSiblingProperties.synthesize` forces `iceberg.catalog.type=hms`), so iceberg's `buildTableDescriptor` takes its **hms branch** (`IcebergConnectorMetadata.java:677-684`) emitting the **identical** construction — it never reaches the `ICEBERG_TABLE` branch. **Legacy parity confirmed**: `HMSExternalTable.toThrift` emitted `HIVE_TABLE` **unconditionally**, incl. an iceberg-on-HMS table (`dlaType==ICEBERG`). BE does not consult the descriptor table-type for an iceberg-on-HMS scan (JNI scan; iceberg-ness rides the per-file format params). A divert would add a fresh `hmsClient.getTable(detect)` per `toThrift` purely to reproduce identical bytes. **Keep the existing hive override** (it beats the SPI-default `null → SCHEMA_TABLE` fallback); add no fork. +- **View family `viewExists` / `getViewDefinition` / `dropView` — NO_DIVERT (legacy-parity AND undiscriminable name-only).** Two independent reasons: + 1. **Parity.** For the supported iceberg-on-HMS **TABLE** (`table_type=ICEBERG`, no view text), `viewExists`=`isViewTable(getTable)` keys on HMS view-text presence → **false**, keeping it on the table path where `getTableHandle` already diverts (S4). A hive view → true → hive view path. An iceberg-on-HMS **VIEW** stores a **hive-dialect SQL** in HMS `viewOriginalText` (iceberg `HiveViewOperations.newHMSView`), so it is served through the hive view path — byte-parity with legacy `HMSExternalTable.isView`/`getViewText` (which was view-text-only, dlaType-independent). *(This last is a runtime HMS-metadata fact about the bundled `iceberg-hive-metastore` lib, PLAUSIBLE but not verifiable from fe HEAD; it does not change the conclusion either way.)* + 2. **Undiscriminable.** A name-only method has no handle, and `HiveTableFormatDetector.detect` returns **UNKNOWN** for an iceberg view (its `table_type='iceberg-view'` ≠ `'ICEBERG'`, and a view has no data input format). So the "re-run detect and forward" strategy that works for TABLES **cannot classify a view at all**. +- **`listViewNames` — NO_DIVERT (a divert would REGRESS).** Deliberately un-overridden: hive `listTableNames` (HMS `get_all_tables`) already includes every `VIRTUAL_VIEW`, so the SPI-default empty makes fe-core's `addAll` merge a no-op (each view listed once = legacy parity). Overriding to the sibling (`IcebergConnectorMetadata.listViewNames` → `ViewCatalog.listViews`) would **double-list** every view. +- **`getTableComment` — NO_DIVERT (parity; a divert would REGRESS).** Hive does not override it → SPI default `""`. Legacy `HMSExternalTable.getComment()` returned `""` **unconditionally** for all HMS tables incl. iceberg-on-HMS → exact byte-parity. Iceberg's own override returns the real comment, so a divert would surface a comment **legacy never showed**. +- **`getDatabase` / `listDatabaseNames` / `databaseExists` / `listTableNames` / `getProperties` / `supportsCreateDatabase` / `createDatabase` / `getPrimaryKeys` — NO_DIVERT (format-agnostic or inert).** All db/catalog/connector-level; the shared HMS already yields the mixed-catalog union and the sibling wraps the same HMS. Diverting `listTableNames` would **regress** (iceberg's version subtracts views). `getPrimaryKeys` is SPI-default-empty on both connectors (a divert can't change the answer). + +## Residuals for the flip (document, do NOT build in S6) + +1. **`dropDatabase` FORCE cascade — write/DDL residual.** The force branch raw-`hmsClient.dropTable`s each table (no iceberg purge/cleanup). **Legacy parity** (`HiveMetadataOps.dropDbImpl → dropTableImpl(true) → client.dropTable`, no purge) — the HMS entry is removed correctly, it only *leaks* iceberg data/metadata files vs the sibling's `purge=true`. Correcting it needs per-table detect+sibling-forward+location-cleanup → belongs with the **write/DDL delegation substep**, not a thin read divert. +2. **`createTable` engine-routing — write/DDL residual.** Always builds a hive HMS table; a NEW table has nothing to `detect()`. Hive-vs-iceberg CREATE routing is a request/engine decision = write/DDL substep. +3. **`beginTransaction` / `getWritePlanProvider` — write delegation residual.** `HiveConnector.getWritePlanProvider()` has **no per-handle variant** (unlike `getScanPlanProvider(handle)`); routing per-table writes/EXECUTE to an iceberg sibling needs new **per-handle SPI overloads** (see decomposition §6).

Cost-only (extra background FULL auto-analyze), not a correctness bug; no per-handle escape. Gate per-handle or explicitly accept at the iceberg/hudi delegation substep. +5. **`supportsLatestSnapshotPreload` under-admits iceberg/hudi-on-HMS — capability-shaped residual (NOT enum-backed).** fe-core `TableIf` default `false`; `PluginDrivenExternalTable` does not override it.

Default-no-op precedent already exists there (`classifyColumn`, `getDeleteFiles`). +- fe-core query-finish spine **already present and generic**: `QueryFinishCallbackRegistry` + + `QeProcessor.registerQueryFinishCallback` (QeProcessor.java:46 / QeProcessorImpl.java:216-217) invoked inside + `unregisterQuery` via `runAndClear(DebugUtil.printId(queryId))` (QeProcessorImpl.java:212). **Nothing on the + scan side registers a callback today.** No new fe-core lifecycle infra is needed. +- Legacy model to mirror: `HiveScanNode.java:138-149` + `Env.getCurrentHiveTransactionMgr().register(hiveTransaction); ... QeProcessorImpl.INSTANCE + .registerQueryFinishCallback(txnQueryId, () -> Env.getCurrentHiveTransactionMgr().deregister(txnQueryId));`. + +**Touch points (three changes).** +1. **NEW SPI** — `ConnectorScanPlanProvider` (fe-connector-api): add + `default void releaseReadTransaction(String queryId) { }` (no-op default, matching the existing + `classifyColumn`/`getDeleteFiles` default-no-op pattern). +2. **Connector impl** — `HiveScanPlanProvider`: + `@Override public void releaseReadTransaction(String queryId){ readTxnManager.deregister(queryId); }`. + `readTxnManager` (HiveScanPlanProvider.java:86) is the *same* per-connector instance + `HiveConnector.java:79/104` injects into every provider, so `register` (planAcidScan) and `deregister` route + to one manager. +3. **fe-core wiring** — `PluginDrivenScanNode.getSplits()`: after `resolveScanProvider()` returns non-null + (i.e. after the null-guard at ~:911-915, and it must **dominate** `planScan` at ~:965 — register **before** + the `requiredPartitions`-empty short-circuit ~:938), register **unconditionally**: + `String queryId = connectorSession.getQueryId(); QeProcessorImpl.INSTANCE.registerQueryFinishCallback(queryId, + () -> onPluginClassLoader(scanProvider, () -> { scanProvider.releaseReadTransaction(queryId); return null; + }));`. Reuse the existing private-static `onPluginClassLoader` helper (PluginDrivenScanNode.java:516-524) for + the TCCL pin; add an import of `org.apache.doris.qe.QeProcessorImpl`. + +**Why the single `getSplits` site is leak-proof.** Hive can *never* enter connector batch mode: +`HiveScanPlanProvider` overrides neither `supportsBatchScan` (defaults `false`) nor +`planScanForPartitionBatch`, so the batch entry point (`PluginDrivenScanNode.startSplit → +planScanForPartitionBatch`) can never open a hive read txn. `register(txn)` is reachable **only** via +`getSplits → planScan`. Register **before** `planScan` so a `planScan` that opens the metastore txn and then +throws still has its release callback in place (`deregister` on an absent `queryId` is a safe no-op). + +**queryId identity invariant (single string, no conversion).** +`ConnectorSessionBuilder.java:57` (`org.apache.doris.connector`, **not** `datasource`) sets +`b.queryId = ctx.queryId() != null ? DebugUtil.printId(ctx.queryId()) : ""`. So +`session.getQueryId()` == `DebugUtil.printId(...)` == the `runAndClear` key (QeProcessorImpl.java:212) == the +`txnMap` key (`txn.getQueryId()`). One string serves the registry key and the manager key. + +**Traps.** +- **T1 (TCCL — load-bearing).** The callback runs on the `StmtExecutor` thread (unregisterQuery callers + StmtExecutor.java:1035/2188), whose TCCL is the fe-core `app` loader, **not** the plugin loader. + `deregister → txn.commit → hmsClient.commitTxn` dispatches into plugin/hive-metastore/thrift code that + resolves classes by name via TCCL (documented split-brain hazard). The callback **must** wrap + `releaseReadTransaction` in `onPluginClassLoader(scanProvider,...)`; omitting the pin risks + ClassCast/NoClassDef at commit time on a live hive query. +- **T2 (live-but-inert on already-flipped connectors — Class C).** The fe-core registration is + **unconditional**, so it runs **today** for every live plugin scan (es/jdbc/paimon/max_compute/iceberg). For + them the callback pins TCCL and calls the no-op default `releaseReadTransaction` — functionally inert but + genuinely exercised. This is why item 1 is behavior-preserving yet **not strictly dormant**: the default + no-op must never throw; per-query cost is one extra `CopyOnWriteArrayList` entry. **Do NOT** gate it with any + `if(hive)`/`instanceof`/`isTransactional` branch (IRON RULE). +- **T3 (connector-agnostic gate).** `HiveConnector.getScanPlanProvider(handle)` (HiveConnector.java:120-124) + returns the **iceberg sibling** provider for a foreign handle, whose default `releaseReadTransaction` is a + no-op — no hive read txn is opened for iceberg-on-HMS, so nothing to release. +- **T4 (pre-existing multi-ACID-table parity limitation — do NOT fix here).** `HiveReadTransactionManager` keys + `txnMap` by `queryId`; a query joining two full-ACID hive tables runs `planAcidScan` twice with the same + `session.getQueryId()`, so the 2nd `register()` overwrites the 1st and that 1st metastore txn leaks. Legacy + `HiveTransactionMgr` has identical keying — the plugin faithfully preserves parity. Out of scope for item 1. +- **T5 (id scoping).** The release must key on `session.getQueryId()` (== `DebugUtil.printId`). A future + refactor passing a raw `TUniqueId` string would make `runAndClear` never match (silent lock leak) or + `deregister` miss the `txnMap` key. Keep the single-string invariant. + +**Proving test (two, both provable now).** +1. **Connector** (fe-connector-hive, mirror `HiveReadTransactionTest` with its fake `HmsClient`): drive + `planAcidScan → register` (assert `openTxn` fired, shared lock acquired), call + `HiveScanPlanProvider.releaseReadTransaction(queryId)`, assert `commitTxn(txnId)` fired **exactly once** and a + second call is a no-op (idempotent `txnMap.remove`). Encodes WHY: an unreleased read txn leaks the metastore + shared lock. **Do not** assert an exception surfaces on commit failure — HEAD swallows+logs it (T-above). +2. **fe-core** (mirror `PluginDrivenScanNode…SelectionTest`/`MvccPinTest` Mockito style): stub + `resolveScanProvider()` to a Mockito `ConnectorScanPlanProvider`, run `getSplits()`, capture the `Runnable` + passed to a mocked `QeProcessorImpl.registerQueryFinishCallback` (verify registered with + `session.getQueryId()` and **before** `planScan`), invoke it, verify `releaseReadTransaction(queryId)` is + called with TCCL pinned to the provider's classloader. `QueryFinishCallbackRegistryTest` already proves + `runAndClear` fires+clears per-query, so registry semantics need no new test. **Add**: a live-connector + no-regression check (paimon/iceberg scan still green) since the registration is unconditional. + +**Deps / risk.** Independent of items 2/4/5. **Coupled to item 3** as the two halves of the read cutover: +item 1 wires the NEW plugin-side release; item 3 DELETES the legacy `Env.hiveTransactionMgr` + legacy +`HiveScanNode`.

The +generic base reads it: `ExternalCatalog.java:1319-1320` +`public String bindBrokerName(){ return catalogProperty.getProperties().get(HMSExternalCatalog.BIND_BROKER_NAME); +}` — a fe-core **base-class → HMS-subclass** constant dependency (import at ExternalCatalog.java:44). Repo-wide, +`HMSExternalCatalog.BIND_BROKER_NAME` has **exactly one** external reference (ExternalCatalog.java:1320) plus its +definition; `HMSExternalCatalog` appears in `ExternalCatalog.java` **only** at the import (:44) and :1320. +`bindBrokerName()` itself has multiple callers, all unaffected because the resolved key is unchanged +(HiveScanNode.java:125/210/239, DefaultConnectorContext.java:318, HiveTableSink.java:161; mocked in +HiveScanNodeTest.java). + +**Touch points (fe-core only, no connector/SPI surface).** +1. `BrokerProperties.java:58` `private → public` on `BIND_BROKER_NAME_KEY`. +2. `ExternalCatalog.java:1320` `HMSExternalCatalog.BIND_BROKER_NAME → BrokerProperties.BIND_BROKER_NAME_KEY`, + keeping the exact `catalogProperty.getProperties().get(...)` shape. +3. `ExternalCatalog.java:44` remove the now-unused `import …hive.HMSExternalCatalog;`, add + `import …datasource.property.storage.BrokerProperties;` (same fe-core module). +4. `HMSExternalCatalog.java:60` delete the constant. + +This also satisfies an iron-rule cleanup: the generic `ExternalCatalog` base no longer imports/depends on the +HMS subclass. + +**Traps.** +- **Preserve exact lookup semantics.** `bindBrokerName()` uses case-**sensitive** `Map.get("broker.name")`, + whereas `guessIsMe` uses `equalsIgnoreCase`. **Do NOT harmonize** `bindBrokerName` to case-insensitive while + relocating — that would silently change the resolved broker name for every catalog that set a differently-cased + key.

Consumers: +- `paddingEngineName` (CreateTableInfo.java:911-922): pre-flip hms hits :913 `instanceof HMSExternalCatalog → + ENGINE_HIVE`; **post-flip** it misses :913, reaches :915-916 `instanceof PluginDrivenExternalCatalog && + pluginCatalogTypeToEngine(...) != null` which is **false** (null) → falls to :921 `throw "Current catalog does + not support create table"`. +- `checkEngineWithCatalog` (:386-395) mirrors the same pattern. + +**Touch point (fe-core only, single line).** Add to the switch: +`case "hms": return ENGINE_HIVE;`.

The read spine (S0–S6) forwards all reads. This decomposition finishes the **write / ALTER TABLE EXECUTE / ALTER-DDL** side. + +**DECISION — LOCKED (user sign-off 2026-07-08): UPGRADE to full native-iceberg capability.** Post-flip, an iceberg-on-HMS table gains the SAME write / DELETE / MERGE / OVERWRITE / EXECUTE / ALTER-DDL capability as a standalone `type=iceberg` catalog (because the sibling IS an `IcebergConnector`). Legacy rejected all three (writes at `BindSink` "target is not a Hive table"; EXECUTE because `HMSExternalTable` is not a `PluginDrivenExternalTable`; ALTER through hive `HiveMetadataOps`). So the write delegation is a deliberate, documented **upgrade over legacy**, not byte-parity — aligned with Trino (the handle identifies the connector; write/DDL dispatch per-handle) and with Doris's already-shipped `getScanPlanProvider(handle)`. + +**E2E REQUIREMENT (user, 2026-07-08 — memory `hms-iceberg-delegation-needs-e2e`):** every new iceberg-on-HMS capability (write / ALTER / procedure) MUST get an e2e regression test before it is considered done. Dormant unit tests prove ROUTING only, not cross-loader cast / commit / worker-pool behavior. Add them "择机" (at an opportune point) once the write substeps land — one heterogeneous HMS catalog (plain-hive + iceberg-on-HMS), run INSERT/DELETE/MERGE/OVERWRITE + ALTER ADD/RENAME/branch-tag/partition-field + ALTER TABLE EXECUTE, assert same result as a native `type=iceberg` catalog on the same table. + +## 1. The three divert SHAPES (recon-delimited) + +The write/procedure/DDL surface splits into **three structurally distinct** divert mechanisms: + +- **Shape A — per-handle SPI overload on `Connector`** for the write/procedure GETTERS that are connector-level today (no handle): `getWritePlanProvider()` (`Connector.java:74`), the 7 admission views (`supportedWriteOperations`/`supportsWriteBranch`/`requires*`, `:83-125`), `getProcedureOps()` (`:131`). Mirror `getScanPlanProvider(handle)` (`:66-68`): add a `(ConnectorTableHandle)` overload whose default delegates to the no-arg version; `HiveConnector` overrides the ONE real spine (`getWritePlanProvider(handle)` / `getProcedureOps(handle)`) with `instanceof HiveTableHandle` guard-forward. Needs fe-core call-site edits to pass the handle (some sites resolve it one line later; some run at analysis time before a handle exists). +- **Shape B — `ConnectorMetadata` handle-guard-forward** (S3 family, ZERO new SPI) for the mutators that ALREADY carry a handle: 14 ALTER-DDL + 2 write-validators + (`dropTable`/`truncateTable` already done). **✅ W1 landed this.** +- **Shape C — session-bound transaction selection** (`beginTransaction`, no handle today, mints a `HiveConnectorTransaction` unconditionally at `HiveConnectorMetadata:1353`). `IcebergWritePlanProvider.currentTransaction` casts `session.getCurrentTransaction()` to `IcebergConnectorTransaction` → **CCE for an iceberg-on-HMS write**. Neither the scan-seam nor the metadata guard-forward precedent solves this; the design must thread the target handle to the txn-open site (W4). + +## 2. Ordered dormant sub-steps + +- **✅ W1 — ALTER-DDL + write-validation guard-forwards (Shape B, ZERO new SPI). DONE (`e7a96f439e7`).** 14 ALTER-DDL mutators forward foreign handles to the sibling / reproduce the exact SPI-default throw for hive; 2 validators forward / return SILENTLY for hive (a throw would newly reject legal plain-hive DML — the one real trap). No fe-core change (ALTER call sites already handle-based via `PluginDrivenExternalCatalog.resolveAlterHandle`; `getTableHandle` already S4-diverts iceberg). Tests: sibling-delegation +2 (foreign completeness lock over all 16 + hive throw/no-op + never-consult-sibling). 209 module tests green, checkstyle 0, import gate clean. +- **W2 — `getWritePlanProvider(ConnectorTableHandle)` overload + `HiveConnector` divert + fe-core provider-fetch conversion (Shape A spine).** Add `default getWritePlanProvider(handle){ return getWritePlanProvider(); }` on `Connector`; `HiveConnector` overrides = `handle instanceof HiveTableHandle ? getWritePlanProvider() : getOrCreateIcebergSibling().getWritePlanProvider(handle)`. fe-core: 4 sites where the handle is resolved ~1 line later — `PhysicalPlanTranslator:654`(DELETE/MERGE, handle :655) + `:702`(INSERT, handle :703) hoist getTableHandle above the provider fetch; `PhysicalIcebergMergeSink:302`(handle :308); `PluginDrivenExternalTable.fetchSyntheticWriteColumns:525`(handle :531). Connector-agnostic (a per-handle overload call, IRON-RULE OK). Deps: none (W1 optional-adjacent). Risk LOW routing; TCCL deferred to W6. +- **W3 — 7 write-admission per-handle overloads (default-derived) + fe-core admission conversion (Shape A leaves).** Add `supportedWriteOperations(handle)`/`supportsWriteBranch(handle)`/`requires*(handle)`, each null-safe over `getWritePlanProvider(handle)` — so once W2 diverts the provider they auto-return iceberg's answers with NO extra `HiveConnector` override (minimal-surface). fe-core: (a) `PhysicalPlanTranslator:648/697` hoist getTableHandle; (b) the handle-LESS analysis-time gates — `RowLevelDmlRowIdUtils:133`, `IcebergRowLevelDmlTransform:93` (the load-bearing DELETE/MERGE detectors), `InsertOverwriteTableCommand:336/351`, `InsertIntoTableCommand:794`, and the `PluginDrivenExternalTable` requires* wrappers (`115/233/249/263/278` + `BindSink:800/811`) — resolve a handle via `PluginDrivenExternalTable.resolveConnectorTableHandle` (`:100`, verified present). **MEDIUM risk:** `supportedWriteOperations(handle)` is load-bearing — without it iceberg-on-HMS DELETE/MERGE is silently not recognized as row-level DML; `requiresMaterializeStaticPartitionValues` (hive false vs iceberg true) and `requiresPartitionHashWrite` (hive true vs iceberg false) genuinely DIFFER, so a partial conversion mis-plans. Deps: W2. +- **W4 — `beginTransaction(session, handle)` threading (Shape C, the one non-precedented gap).** Add a per-handle `beginTransaction` on `ConnectorWriteOps`; `HiveConnectorMetadata` guard-forwards to `siblingMetadata` for a foreign handle so the session-bound txn is the sibling's `IcebergConnectorTransaction` (else `IcebergWritePlanProvider.currentTransaction` CCEs). Thread the resolved write-target handle into the engine's txn-open call. **DECISION (recommended, needs confirm at W4): option-1 per-handle `beginTransaction(session, handle)` guard-forwarded** (direct S3-family member, matches Trino's handle-bound `beginInsert`). Deps: W2. MEDIUM risk (only genuinely new shape). +- **W5 — `getProcedureOps(ConnectorTableHandle)` overload + `HiveConnector` divert + `ConnectorExecuteAction` reorder.** Add `default getProcedureOps(handle){ return getProcedureOps(); }` (null default); `HiveConnector`: hive handle → inherited null (plain-hive has no procedures, correct), foreign → sibling. fe-core `ConnectorExecuteAction`: hoist the handle-resolution block (`:134-139`) ABOVE the `getProcedureOps()` null-check (`:116`) + `getExecutionMode` (`:123`). Net-new capability (per §0 decision). Reorder changes failure-message ORDER (bad table name now throws "Table not found" before "does not support EXECUTE") — verify no test pins precedence. `ExecuteActionFactory.getSupportedActions` (`:84`, SHOW discovery) has NO live caller → its handle-aware variant deferred. Deps: none (independent of write set). MEDIUM risk (net-new). +- **W6 — write-path TCCL pin verification (flip-time, NOT dormant-testable).** Scan auto-pins via `PluginDrivenScanNode.onPluginClassLoader`; the write path has NO analogue — the sibling `IcebergWritePlanProvider`'s name-based reflection (planWrite `PhysicalPlanTranslator:725`, getWritePartitioning `PhysicalIcebergMergeSink:313`, getSyntheticWriteColumns `PluginDrivenExternalTable:535`) runs on fe-core threads under the app loader. **VERIFY first** whether the sibling-internal `TcclPinningConnectorContext.executeAuthenticated` wraps `planWrite`'s `TDataSink` construction (not just the deep commit); if unpinned, add an fe-core write-path pin keyed off `provider.getClass().getClassLoader()` (connector-agnostic). Deps: W2. The load-bearing unknown of the write step — flip-time e2e only. + +**Ordering rationale.** W1 first (cheapest, no SPI, no fe-core). W2 is the spine every admission derives from. W3 depends on W2 (auto-derive). W4 after the planning-only diverts. W5 independent (schedule after write core, net-new decision). W6 last (flip-time risk). **W2+W3+W4+W6 are the "write execution" bundle — all must land before the flip; W1 and W5 are independently committable.** Every substep is dormant (nothing runs until `hms` enters `SPI_READY_TYPES`). + +## 3. Residuals for the flip (document, do NOT build in the write substeps) + +1. **THE flip line:** add `"hms"` to `CatalogFactory.SPI_READY_TYPES` (`:50`) — the single residual that ends dormancy for the whole write/procedure/DDL spine. +2. **HUDI-on-HMS write parity (flip-blocker for hudi).** `getTableHandle` diverts ONLY ICEBERG → a hudi table keeps a `HiveTableHandle` and (post-W2) routes to the HIVE write provider; `HiveConnectorTransaction` likely does NOT reject non-transactional hudi. The iceberg write step must NOT silently make read-only hudi-on-HMS writable-as-hive — add an explicit hudi-write reject in the hive write path, or close it in the dedicated hudi-delegation substep, before the flip. +3. **Hive ALTER-DDL / RENAME port.** W1's hive branch throws "... not supported" (current connector behavior); if legacy supported any hive ALTER through `HiveMetadataOps`, that would regress at the flip unless the hive connector ports it. Separate hive-DDL concern, not iceberg delegation. +4. **`createTable(format=iceberg)` engine-routing.** A NEW table has no handle to `detect()`; hive-vs-iceberg CREATE routing is a request/engine decision + `pluginCatalogTypeToEngine` has no `"hms"` entry (`CreateTableInfo`). Write/DDL residual. +5. **`dropDatabase` FORCE cascade.** Raw `hmsClient.dropTable` per table, no iceberg purge (legacy parity — only leaks iceberg files). Per-table detect+sibling-forward+cleanup belongs with the write/DDL substep. +6. **§4.5 write-chain items:** read-ACID query-finish commit unwired; `BindSink` explicit-partition-spec INSERT reject not yet ported into the hive plugin (only the LZO reject is, `HiveSinkHelper:85`); `Env.hiveTransactionMgr` relocation; `BIND_BROKER_NAME` relocation. +7. **E2E gate (per §0):** the ONLY place write/procedure/DDL correctness is actually exercised — every substep is dormant + unit tests prove routing only. + +## 4.

The connector's hudi +schema must expose `_hoodie_commit_time`, `_hoodie_commit_seqno`, `_hoodie_record_key`, +`_hoodie_partition_path`, `_hoodie_file_name` as visible columns (port legacy `HMSExternalTable.initHudiSchema` +meta-column set / `getTableAvroSchema(true)` — DV-008 gap-2). This also makes `_hoodie_commit_time` naturally +materializable for the incremental filter (no separate hidden-column path needed) and restores legacy +`SELECT _hoodie_commit_time`.

This is the single genuinely-new design problem (§3B). + +--- + +## 2. PhysicalHudiScan routing analysis (the connector-agnostic answer) + +**Question:** after the flip, how does a hudi-on-HMS table reach a hudi-aware scan carrying +incremental/snapshot params, given the "KEY WRINKLE" that hudi uses a distinct `PhysicalHudiScan` node? + +**Answer (HEAD-verified — the wrinkle dissolves; the flipped table rides the GENERIC path):** + +1. **Binding.** `BindRelation` builds `LogicalHudiScan` **only** for `case HMS_EXTERNAL_TABLE` gated on + `hmsTable.getDlaType() == DLAType.HUDI` (`BindRelation.java:603-609`) — i.e. only for a **legacy** + `HMSExternalTable`. The `case PLUGIN_EXTERNAL_TABLE` arm (`:623, :654-658`) **unconditionally** returns a + plain `LogicalFileScan`, carrying `unboundRelation.getScanParams()` (so `@incr`/AS-OF params are **not lost** + at the plan-tree level — resolution just moves connector-side). +2. **Post-flip table class.** When `"hms"` enters `SPI_READY_TYPES`, an hms catalog becomes a + `PluginDrivenExternalCatalog` and its hudi table is a `PluginDrivenMvccExternalTable` (the gateway declares + `SUPPORTS_MVCC_SNAPSHOT` catalog-wide) — `getType() == PLUGIN_EXTERNAL_TABLE`. So it binds to + `LogicalFileScan`, **never** `LogicalHudiScan`. +3. **Translation.** `LogicalFileScan → PhysicalFileScan → PhysicalPlanTranslator.visitPhysicalFileScan` + (`:803`), whose `table instanceof PluginDrivenExternalTable` branch (`:814-822`) routes to the **generic** + `PluginDrivenScanNode` (identical path to iceberg/paimon). `visitPhysicalFileScan` also threads + `getTableSnapshot()`/`getScanParams()` onto the node (`:865-866`), which + `PluginDrivenScanNode.pinMvccSnapshot` → `MvccUtil` resolves via the connector. +4. **The `visitPhysicalHudiScan` fail-loud is DEAD for the flipped path.** Its `PluginDrivenExternalTable` + branch with the incremental throw (`:909-910`) and the time-travel throw (`:913-914`) is **unreachable** — + nothing ever binds a `PluginDrivenExternalTable` to a `LogicalHudiScan`. **Correction to the task framing:** + `visitPhysicalHudiScan:901-919` is *not* the real flip control point; deleting those throws is a no-op for + the flipped path. The real no-regression channel is the generic MVCC seam below. + +**The connector-agnostic seam for incremental + time travel (already built, connector-agnostic, used by +paimon today):** `PluginDrivenMvccExternalTable.loadSnapshot` (`:319`) → `toTimeTravelSpec` (`:328`, mapping +`@incr` → `ConnectorTimeTravelSpec.incremental(params.getMapParams())` at `:416-417`, FOR TIME/VERSION AS OF +otherwise) → `metadata.resolveTimeTravel(session, handle, spec)` (`:347`). An **empty** resolve throws a +kind-specific user error `notFoundMessage(spec)` (`:349`) — i.e. today an `@incr`/AS-OF query on hudi would +**fail loud** (a regression, since legacy served it), not silently read latest. The resolved snapshot is +pinned onto the handle via `metadata.applySnapshot` (`:375`) before `planScan`. **Paimon fully implements +this** (`PaimonConnectorMetadata.resolveTimeTravel :498` with the `INCREMENTAL` case `:552`, `beginQuerySnapshot +:432`) — it is the exact template for hudi. + +**Consequence for the plan:** do **not** try to route a plugin hudi table to `LogicalHudiScan` (that requires a +source-specific `detect==HUDI` arm in `BindRelation` = iron-rule violation, and drags `org.apache.hudi.*` + +`HMSExternalTable` casts into fe-core). Serve hudi-on-HMS through the generic `PluginDrivenScanNode`. Re-home +incremental + time travel **connector-side** via `resolveTimeTravel`/`applySnapshot`/a pin-honoring +`planScan`. Delete the bespoke `LogicalHudiScan`/`PhysicalHudiScan`/`HudiScanNode` + the 4 fe-core +`*IncrementalRelation` classes at flip-time (§4), after porting their logic into `fe-connector-hudi`. + +**No new fe-core SPI is required** for incremental/time-travel — `ConnectorTimeTravelSpec.Kind.INCREMENTAL` +and the whole `loadSnapshot` dispatch already exist.

Today the hudi connector emits **nothing** for schema-history → BE `can_map_by_history_schema` returns false (`be/src/format_v2/table/schema_history_util.cpp:124`) → `BY_NAME` fallback (case-insensitive `to_lower` matching). That safe baseline is correct for plain/add/drop/reorder reads but a **renamed** column reads NULL on old files (its old physical name no longer matches the new table name). To reach legacy parity the connector must drive BE's `BY_FIELD_ID` path by emitting field-ids + a per-version schema history + a per-split schema id, and must resolve schema **at the pinned instant** for time travel. + +--- + +## 1. BE contract (what FE must populate — NO BE code changes) + +BE's native format_v2 hudi machinery is **already in place and identical to paimon** (`be/src/format_v2/table/hudi_reader.cpp:30-52` mirrors `paimon_reader.cpp:36-55`). Field-id mapping engages **only** when ALL of the following are populated together: + +1. **`TFileScanRangeParams.current_schema_id`** (PlanNodes.thrift field 25) — **keep `-1`** (the sentinel). BE `find_external_root_field` (`be/src/format_v2/table_reader.cpp:254`) selects the history `TSchema` whose `schema_id == current_schema_id` as the *target overlay* and stamps each projected table column `identifier = TYPE_INT(field.id)` from it (`:514`). A real id equal to any per-split id would drive the **v1** engine's `current==split → ConstNode` case-sensitive verbatim-name path (`be/src/format/table/table_schema_change_helper.h:243`) = **the banned half-fix**. `-1` is `!= ` every split id (splits are `>=0`) ⇒ always the field-id path. +2. **`TFileScanRangeParams.history_schema_info`** (field 26, `list`) covering: (a) one `TSchema{schema_id=-1}` — the *target/current* overlay, built from the **requested** columns (names == BE scan slots by construction, the CI-969249 `StructNode` DCHECK invariant); (b) one `TSchema` per distinct per-split `schema_id` in the scan. Each `TField` MUST carry `id` (InternalSchema field id, **stable across renames**), `name` (**physical file column name in THAT version**), `type` (`TColumnType`), and `nestedField` for struct/array/map — `id`+`name` at **every** nesting level. +3. **`THudiFileDesc.schema_id`** (field 12, **native reader only**) = the InternalSchema version of the commit that wrote that base file; `>=0` and present in `history_schema_info`. Unset/`-1` ⇒ `BY_NAME` (safe, no evolution). + +**Mapping mechanics** (`schema_history_util.cpp:132`, `column_mapper.cpp:102`): file columns are stamped with the split-schema's field-ids by `to_lower(name)` match against the physical file columns; table columns are stamped with the `-1`-entry ids; `FieldIdMatcher` maps table→file **purely by integer id** — a rename works because the same id appears under a different name in the `-1` vs split `TSchema`. A missing id ⇒ `ranges::find_if` end ⇒ nullptr ⇒ column becomes missing/const **silently** (no throw). ⇒ **populate `id` at EVERY level of EVERY `TSchema`** or you get silent corruption strictly worse than `BY_NAME`. + +**JNI / MOR-realtime path** (`be/src/format_v2/jni/hudi_jni_reader.cpp`) consumes **no** schema_id / history / field-id. It forwards `hudi_params.column_names` + `column_types` (fields 8/9) + `instant_time` verbatim to `HadoopHudiJniScanner` and projects by `table_column.name`. So MOR evolution correctness is **entirely FE-supplied** = HD-C5. + +**Lowercase rule (load-bearing).** format_v2 hudi is fully case-insensitive (`to_lower` everywhere) and cannot SIGABRT.

Same logical column = same id across versions **only** through the mode-aware path. +- **Per-file `schema_id`** (`HudiScanNode.setHudiParams:304-323`): native branch only; `FSUtils.getCommitTime()` → `InternalSchemaCache.searchSchemaAndCache` (evolution) = real versionId, else `convert()` = **0** (never `-1`; JAR-confirmed). JNI branch never sets it. +- **`TField` builder** (`HudiUtils.getSchemaInfo:350-421`): port as a self-contained `Types.Field → TField` converter — but **add every-level lowercasing** (legacy lowercases nothing, `:363`) and emit STRING-placeholder scalar type (legacy emits full Doris type `:407-410` — drop it). +- **Schema-at-instant** (`HudiScanNode.doInitialize:206-224`, `getSchemaCacheValue` keyed by `(nameMapping, queryInstant)`): resolve columns/colTypes/ids AT the pinned instant. **Legacy limitation to mirror:** `getTableInternalSchemaFromCommitMetadata` honors the instant **only** when schema.on.read is enabled; else falls back to LATEST avro. For a non-evolution table this is byte-equivalent (schema never changed). +- **metaClient/storage coupling** (HD-C1/C2): `hmsTable.getHudiClient()` → connector metaClient; every timeline/InternalSchema/`searchSchemaAndCache` touch on the metadata thread must be wrapped in `HudiMetaClientExecutor.execute` (legacy left `getHudiTableSchema`/`getCommitInstantInternalSchema` UNWRAPPED — the port must be STRICTER, iron rule). `getScanNodeProperties`/`planScan` already run on the TCCL-pinned scan thread. + +--- + +## 4.

Zero fe-core import. *Test (fully same-loader):* hand-build an InternalSchema with a mixed-case nested struct child; assert every emitted `TField.name` lowercased at every level, current/history round-trips base64, scalar `type.type==STRING`, nested ARRAY/MAP/STRUCT tags. Mirror `HudiSchemaParityTest`. **deps: none.** +- **HD-C4b — field-ids onto `HudiColumnHandle`.** Add `int fieldId` (default `ConnectorColumn.UNSET_UNIQUE_ID=-1`; ctor+getter; **KEEP equals/hashCode by name** like `IcebergColumnHandle:55-69` — do NOT add id to identity).

Factor a **shared static per-file→schemaId resolver** into `HudiSchemaUtils` that C4d reuses. *Test:* stamping is same-loader (`HudiScanRangeTest`: Builder→populateRangeParams asserts field 12 set on native, UNSET on JNI); the id value is e2e. **deps: shares resolver with C4d.** +- **HD-C4d — scan-level dict emission + apply (steady-state / no-pin).** `getScanNodeProperties` builds a base64 `hudi.schema_evolution` prop = `current_schema_id(-1)` + the `-1` entry from the **requested** columns arg + one entry per **referenced-split** InternalSchema version (via the C4c shared resolver + C4a converter). OVERRIDE `populateScanLevelParams` to copy fields 25/26.

HARD-ORDER after C4c** (a dormant prefix flipping with the dict present while per-split `schema_id` is unset(`-1`) is the forbidden `current==file==-1` v1-ConstNode degrade — land C4c+C4d back-to-back). +- **HD-C5a — schema-at-instant column list (`getTableSchema` 3-arg override).** Override `ConnectorTableOps.getTableSchema(session,handle,snapshot)` on `HudiConnectorMetadata` (ABSENT today → SPI default returns latest = HD-C2 residual #1). Key off `HudiTableHandle.getQueryInstant()` (NOT `snapshot.getSchemaId()` which stays `-1` for hudi); null instant → delegate to the 2-arg latest path (shared build-path so latest/at-instant can't drift). Resolve InternalSchema AT the instant WRAPPED in `HudiMetaClientExecutor.execute` (also closes the existing unwrapped `getSchemaFromMetaClient` gap). Hive delegation already shipped ⇒ no hive change. *Test:* null-instant→latest delegation branch is same-loader; the at-instant read is e2e. **deps: C4b.** +- **HD-C5b — scan-side at-instant: MOR/JNI column list + `-1` entry at pinned instant.** (i) `planScan` JNI `column_names`/`column_types` re-derived from the queryInstant-scoped schema (replacing latest `getTableAvroSchema(true)`) — legacy `HudiScanNode:222-224`; keep BOTH schema loci in lockstep. (ii) The dict `-1` entry re-resolved against the **pinned** InternalSchema (iceberg full-pinned / empty-requested) because handle ids are latest-keyed — else a renamed column drops a BE slot. `current_schema_id` stays `-1`. All off-scan-thread timeline touches under `HudiMetaClientExecutor.execute`. *Test:* almost entirely e2e; FE-unit asserts that GIVEN an instant-resolved schema the JNI col list + `-1` overlay derive from IT not latest (the pure `chooseJniSchema` / full-pinned empty-requested assembly seams). The at-instant resolution + the provider pin-routing (`if (pinnedSchema.isPresent())`) themselves need a live metaClient, so a mutation that ignores the pin is only caught at flip-time e2e. **deps: C4c, C4d, C5a.** **STATUS: DONE** (`e0da87888e5`; 4-dim adversarial review `wf_ec6d47e3-37e` — 0 production defects, 1 confirmed-minor test-comment honesty fix applied, 1 nit). + +--- + +## 6.

Hudi has no `SchemaManager.listAllIds()`. The C4c per-file resolver already computes each selected split's `schema_id`; the C4d dict emits `-1` + exactly those referenced ids. Self-consistent by construction (every emitted split id is in history ⇒ no BE fail-loud "miss schema info"), cheaper than enumerating history, and byte-faithful to legacy's per-referenced-file `putHistorySchemaInfo` (just up-front at plan level, not lazy). ⇒ C4c and C4d share the resolver and land back-to-back. +- **D2 — `current_schema_id` stays `-1`, `-1` entry made pinned-correct under time travel** (C5b), rejecting the time-travel reader's "emit a real current_schema_id" (would risk the v1 `ConstNode` case-sensitive degrade; paimon + legacy both emit `-1`). +- **D3 — non-evolution FOR TIME AS OF mirrors legacy's latest-fallback.** For a non-evolution table the schema never changed via InternalSchema, so "latest" == "at-instant" — byte-equivalent. Evolution (schema.on.read) tables get true schema-at-instant. No extension beyond legacy. +- **D4 — keep field-id on the handle (C4b).** Mirrors legacy `updateHudiColumnUniqueId` + the plan mandate; the steady-state `-1` entry reads ids from the requested handles directly; same field-id also unblocks future nested-column-prune. Paimon-style provider-side name-resolution was the simpler alternative but diverges from legacy and would still need C5b re-resolve under pin anyway. +- **D5 — scalar `TColumnType` = STRING placeholder** (BE by_table_field_id uses `type.type` only as a nested-vs-scalar discriminator; don't port the legacy full avro→Doris type map). + +--- + +## 7. Correctness gates / landmines + +1. **Half-fix ban**: never engage `BY_FIELD_ID` (split id `>=0` + history set) with any `TField.id` unset → silent column drop.

The mechanism (how the pin reaches planScan) — verified + +The pin flows through the generic MVCC seam exactly like paimon. NO fe-core edit is needed; all four SPI hooks +already dispatch generically: + +1. fe-core `PluginDrivenMvccExternalTable.loadSnapshot` (`:347`) calls `metadata.resolveTimeTravel(session, + handle, spec)` for an explicit `FOR TIME AS OF` and stores the resolved `PluginDrivenMvccSnapshot` in the + statement context (`StatementContext.loadSnapshots`, keyed by table + version selector). The `pinnedHandle` + it computes at `:375` is **discarded** (used only for `getTableSchema`); the surviving carrier is the opaque + `ConnectorMvccSnapshot`. +2. At scan time `PluginDrivenScanNode.pinMvccSnapshot` (`:749`) does a **version-aware** lookup + (`MvccUtil.getSnapshotFromContext` keyed by *this scan's* `getQueryTableSnapshot()` selector), so a + `FOR TIME AS OF` query retrieves the **resolveTimeTravel-resolved** snapshot (my property), while a normal + read retrieves the query-begin latest-pin snapshot (empty properties). +3. `applyMvccSnapshotPin` (`:732`) unwraps `getConnectorSnapshot()` and calls + `metadata.applySnapshot(session, currentHandle, connectorSnapshot)`; the result becomes `currentHandle` + (`:768`), which is exactly the handle passed to `scanProvider.planScan(session, currentHandle, ...)` + (`:998-1000`). + +**Consequence:** the pin must live on the `ConnectorMvccSnapshot` (a String property) and be re-derived by +`HudiConnectorMetadata.applySnapshot` onto the `HudiTableHandle`; a value stamped only on `loadSnapshot`'s +handle would never reach `planScan`. `ConnectorMvccSnapshot.getProperties()` is **not** serialized to BE for a +plugin scan (fe-core only feeds it to `applySnapshot`); the instant reaches BE **only** via the per-range +`THudiFileDesc.instantTime` that `planScan` already stamps for MOR-JNI slices. So carrying the instant as a +handle field is both necessary and sufficient. + +## 2. Decisions + +### D1 — TIMESTAMP is permissive; NO timeline validation. **(plan correction)** +Legacy `HudiScanNode` never validates a `FOR TIME AS OF` value against the timeline: it only does +`value.replaceAll("[-: ]", "")` (`HudiScanNode.java:211`) and `getLatest{BaseFiles,MergedFileSlices}BeforeOrOn` +(`:419`/`:435`) — **before-or-on** file selection. A value after all commits reads the latest slice; a value +before the earliest commit reads **empty** (0 rows). Legacy **never errors** on a well-formed FOR TIME AS OF +(only the VERSION rejection). The written HD-C2 plan text ("validate the instant exists … empty ⇒ +notFoundMessage") is a paimon-ism that would ADD an error where legacy read empty = a regression. **Corrected:** +`resolveTimeTravel(TIMESTAMP)` normalizes and **always returns a non-empty pin** for a well-formed value; it +never returns empty and never throws for not-found. This is byte-faithful, keeps the method fully offline +unit-testable (no live metaClient, zero extra round-trip), and preserves before-or-on at `planScan` unchanged. + +### D2 — SNAPSHOT_ID / VERSION_REF fail loud by THROWING the byte-for-byte legacy message. **(mechanism correction)** +Legacy rejects `FOR VERSION AS OF` for hudi (`HudiScanNode.java:208-209`). fe-core's `toTimeTravelSpec` maps a +digital `FOR VERSION AS OF` → `SNAPSHOT_ID` and a non-digital one → `VERSION_REF` +(`PluginDrivenMvccExternalTable.java:404-407`); **both** must be rejected. Returning `Optional.empty()` would +surface fe-core's WRONG-DOMAIN `notFoundMessage` ("can't find snapshot by id" / "…by tag"). To surface the +exact legacy string the connector must **throw** a `DorisConnectorException` (unchecked; propagates verbatim — +no try/catch at `loadSnapshot :347-350`): + +> ``Hudi does not support `FOR VERSION AS OF`, please use `FOR TIME AS OF` `` (verbatim incl. both backtick pairs) + +### D3 — Digital flag ignored (legacy parity). +Legacy strips `[-: ]` regardless of `digital`; it does **no** epoch-millis conversion and **no** session +time-zone parse (unlike paimon). `resolveTimeTravel(TIMESTAMP)` ignores `spec.isDigital()` and just normalizes +the string. (A digital epoch-millis value passes through verbatim and reads before-or-on lexically — a faithful +legacy quirk.) + +### D4 — Pin carrier = MVCC property → handle field. +`resolveTimeTravel(TIMESTAMP)` stashes the normalized instant STRING in +`ConnectorMvccSnapshot.property(HUDI_QUERY_INSTANT_PROPERTY, normalized)` (FE-internal transport, paimon +scan-options model). `applySnapshot` reads that property and stamps +`hudiHandle.toBuilder().queryInstant(v).build()` — **`toBuilder` preserves `prunedPartitionPaths`** (applyFilter +runs before applySnapshot, so a pruned time-travel scan must not lose its pruning). Do **not** overload +`snapshotId` (opaque to fe-core for the TT pin; planScan needs the string; property-presence cleanly +discriminates explicit-TT from latest-pin). `snapshotId` left default — the TT pin never enters an MTMV +comparison (MTMV uses the query-begin pin). + +### D5 — applySnapshot is a no-op for the latest pin (no-regression guard). +`applySnapshot` is also invoked at scan time on the **query-begin** (latest) pin, which carries **empty** +properties (`beginQuerySnapshot` sets only `snapshotId`). When the `HUDI_QUERY_INSTANT_PROPERTY` is absent (or +snapshot null) `applySnapshot` returns the handle **unchanged** → `planScan` falls back to +`timeline.lastInstant()` → **byte-identical** to today for every ordinary read. Mirrors paimon's +`snapshotId<0 ⇒ return handle` guard. + +### D6 — planScan single switch point. +`HudiScanPlanProvider.java:139` changes from `String queryInstant = lastInstant.get().requestedTime();` to +`hudiHandle.getQueryInstant() != null ? hudiHandle.getQueryInstant() : lastInstant.get().requestedTime()`. +All three downstream consumers read this one local — COW `getLatestBaseFilesBeforeOrOn` (`:250`), MOR +`getLatestMergedFileSlicesBeforeOrOn` (`:279`), MOR-JNI `builder.instantTime(queryInstant)` (`:311` → +`THudiFileDesc.instantTime`) — so FE file selection and the BE merge instant stay consistent. The +empty-timeline early-return (`:135-138`) is kept: `lastInstant.get()` is only touched in the null-pin branch +(guaranteed present past `:138`), so no NPE; a pinned instant on a never-committed table still early-returns +empty (correct). Schema/columns (`:144-157`) already resolve LATEST with no instant arg → NOT a switch site +(schema-at-instant is HD-C4). + +### D7 — TAG / BRANCH / INCREMENTAL → `Optional.empty()` (unchanged SPI-default behavior). +The `resolveTimeTravel` override handles TIMESTAMP (pin) and SNAPSHOT_ID/VERSION_REF (throw); every other kind +returns `Optional.empty()` = the same result as not overriding, so no regression. `INCREMENTAL` is HD-C3 (which +will add that case); hudi has no `@tag`/`@branch`. Dormant until HD-B2, so no live behavior depends on this. + +## 3. Implementation checklist (ordered) + +1. **`HudiTableHandle.java`** — add `private final String queryInstant;` + `getQueryInstant()`; Builder field + + `queryInstant(String)` fluent setter; copy in the private ctor and in `toBuilder()` (mirroring + `prunedPartitionPaths`). **No** equals/hashCode (handle has none; keep reference identity, matching paimon's + intent to exclude the pin from identity). +2. **`HudiConnectorMetadata.java`** — override `resolveTimeTravel` (TIMESTAMP → pin property; SNAPSHOT_ID + + VERSION_REF → throw D2 message; default → empty) and `applySnapshot` (property present → stamp via + `toBuilder().queryInstant(...)`; else unchanged). Add the `HUDI_QUERY_INSTANT_PROPERTY` constant. Do **not** + override 3-arg `getTableSchema` (clean latest-schema deferral to HD-C4). +3. **`HudiScanPlanProvider.java:139`** — honor `handle.getQueryInstant()` (D6). + +## 4.

Next work pivoted to the HMS event-pipeline relocation (independent, unblocked). Deletions / per-column stats SPI / `IcebergUtils` extraction are ALL deferred to the flip step regardless. + +## The three verified facts that reframed this work + +**Fact 1 — the delegation seam is UNREACHABLE until the hms catalog/table class flips.** +Scan-node selection is by table **class**, not by connector/handle: +- `PhysicalPlanTranslator.visitPhysicalFileScan` picks `PluginDrivenScanNode` **only** for `table instanceof PluginDrivenExternalTable` (`PhysicalPlanTranslator.java:808`); an HMS table falls into the `else if (instanceof HMSExternalTable)` arm and runs the legacy `switch(getDlaType())` → `new IcebergScanNode(...)` (`:818-847`). +- The per-table scan-provider seam `Connector.getScanPlanProvider(handle)` (landed `0923077fe67`) is consulted **only inside `PluginDrivenScanNode`** (`PluginDrivenScanNode.java:209`). +- HMS is still 100% legacy: `HMSExternalTable extends ExternalTable` (`HMSExternalTable.java:125`, NOT `PluginDrivenExternalTable`); `HMSExternalCatalog extends ExternalCatalog` (`HMSExternalCatalog.java:52`); `CatalogFactory` case `"hms"` builds `new HMSExternalCatalog(...)` (`CatalogFactory.java:133-134`); `HMSExternalDatabase.buildTableInternal` unconditionally builds `HMSExternalTable`. +→ Until the hms catalog is added to `SPI_READY_TYPES` and built as a `PluginDrivenExternalCatalog` (the flip), the gateway's `getScanPlanProvider(handle)` **can never fire** for an iceberg-on-HMS table. Building the delegation before the flip = dead, un-e2e-testable code. + +**Fact 2 — it is NOT "scan-only" delegation; the gateway must route the WHOLE per-table lifecycle to iceberg.** +`IcebergScanPlanProvider` unconditionally casts the handle to `IcebergTableHandle` (`IcebergScanPlanProvider.java:319,364,476`). A `HiveTableHandle` handed to it → `ClassCastException`. So the gateway must produce **iceberg-typed handles** for iceberg tables, i.e. delegate `getTableHandle` / schema / stats / scan / sys-tables / time-travel to an embedded iceberg connector — not just the scan provider. This is Trino's "resolve once at analysis, rebind all ops" shape, kept inside one gateway (D-020) instead of across catalogs. + +**Fact 3 — cross-plugin classloader isolation forbids the naive "add a maven dep" approach.** +Each connector is a **separate plugin zip in its own child-first classloader** (`ConnectorPluginManager` parent-first only for `org.apache.doris.connector.*`/`.filesystem.*`; `DirectoryPluginRuntimeManager` one loader per plugin dir). Corrections to earlier assumptions: +- `fe-connector-hive` deps = spi/api/hms only; it does **NOT** see iceberg classes. `fe-connector-hms` does **NOT** depend on iceberg (the only "iceberg" hit in its pom is a **comment**, line 102). The real edge is reversed: `fe-connector-iceberg → fe-connector-hms`. +- **Co-packaging iceberg into the hive plugin zip is REJECTED**: a second copy of the AWS SDK in a distinct classloader "permanently poisons S3 for the whole JVM" (documented in `fe-connector-iceberg/pom.xml` as paimon RC-3). Iceberg-core/AWS/Caffeine are bundled child-first specifically to keep one copy per loader. + +## The mechanism (locked by the above): cross-plugin sibling-connector handoff + +The gateway (`HiveConnector`) must obtain a **genuinely iceberg-plugin-loaded** `IcebergConnector` and delegate to it. This works because: +- The SPI interfaces (`Connector`, `ConnectorScanPlanProvider`, `ConnectorMetadata`, `ConnectorTableHandle`) are parent-first (single fe-core copy) → a hive-loader object can hold/invoke an iceberg-loader provider type-safely. +- The scan-thread TCCL pin (`PluginDrivenScanNode.onPluginClassLoader`, keys off `provider.getClass().getClassLoader()`) **auto-pins** to the iceberg loader once the returned provider is a real iceberg-loader class — **zero fe-core change, no `if(iceberg)` branch**. + +**New SPI required**: `ConnectorContext` today exposes NO sibling-connector lookup, and `ConnectorPluginManager.createConnector` is fe-core-only. So the flip must add a neutral seam so a gateway connector can obtain a sibling connector **of a named type, built in that type's plugin loader, sharing properties** — e.g. `ConnectorContext.getOrCreateSiblingConnector(type, props)` implemented by fe-core over `ConnectorPluginManager`. The gateway names `"iceberg"` (plugin-side, allowed); fe-core stays connector-agnostic (generic "give me a connector of type X" factory). + +**Trino parallel**: Trino runs one connector per format + *table redirection* — the hive connector reports the table lives in catalog X; the **engine** resolves the redirect once and rebinds ops to the iceberg catalog's connector (in its own classloader). Same "engine mediates the cross-format handoff" shape; Doris keeps one visible `hms` catalog (D-020) so the gateway holds the sibling internally instead of exposing a second catalog. + +## Concrete design sketch (for the flip step) + +1. **Format probe already exists, already runs**: `HiveConnectorMetadata.getTableHandle` calls `HiveTableFormatDetector.detect(HmsTableInfo)` → `HiveTableType` (ICEBERG when table param `table_type=ICEBERG`, case-insensitive; iceberg-before-hudi-before-hive order), baked into `HiveTableHandle.tableType`. Matches legacy `HMSExternalTable.supportedIcebergTable()` exactly. No new probe needed. +2. **Gateway embeds ONE shared `IcebergConnector` per hms catalog** (shared HMS + snapshot/manifest caches + worker-pool pin + TCCL-pinning context + lazy plugin authenticator). Build it via the sibling seam; forward `close()`/`invalidateTable`/`invalidateAll` to it. +3. **Property synthesis (plugin-side)**: an hms catalog's props lack `iceberg.catalog.type`; the gateway must inject `iceberg.catalog.type=hms` (`IcebergConnectorProperties.TYPE_HMS`) before constructing the iceberg connector — else `IcebergCatalogFactory.resolveFlavor` throws "Missing 'iceberg.catalog.type'". Shared `hive.metastore.uris`/`uri` pass through unchanged; `warehouse` is NOT required for the hms flavor (`IcebergHmsMetaStoreProperties.validate` runs only `validateConnection`). Reuses `MetaStoreProviders.bindForType("hms", ...)` → `HmsMetaStoreProperties.toHiveConfOverrides` → `IcebergCatalogFactory.assembleHiveConf` → `CatalogUtil.buildIcebergCatalog`. +4. **Route iceberg-typed tables**: for an ICEBERG handle, the gateway's metadata delegates `getTableHandle`→`IcebergTableHandle`, and `getScanPlanProvider(handle)` returns the embedded iceberg connector's provider (5-arg: properties, catalogOps-over-live-hms-iceberg-catalog, iceberg's TcclPinningContext, shared manifestCache, shared rewritableDeleteStash). Sys tables ($snapshots/$history/$manifests) + time-travel come free once handles are iceberg-typed (`IcebergConnectorMetadata.getSysTableHandle`, `IcebergScanPlanProvider.supportsSystemTableTimeTravel()==true`). +5. **MVCC / table-class**: the base-vs-`PluginDrivenMvccExternalTable` selection (`PluginDrivenExternalDatabase.buildTableInternal`, gated on `SUPPORTS_MVCC_SNAPSHOT`) is unreachable until the catalog flips; it lands WITH the flip. NB open Q: if the hms gateway advertises `SUPPORTS_MVCC_SNAPSHOT`, plain-hive tables would also be built as the Mvcc subclass (plain-hive is `EmptyMvccSnapshot` today) — decide per-table vs table-uniform MVCC capability. + +## Deferred to the flip (NOT this-step work — all blocked) + +- **Delete the ~23 `datasource/iceberg` classes** — two tiers. TIER-1 (scan cluster, deletable once the `case ICEBERG` branch is gone at flip): `IcebergScanNode`, `IcebergHMSSource`, `IcebergSource`, `IcebergSplit`, `IcebergDeleteFileFilter`, `IcebergTableQueryInfo`, `cache/IcebergManifestCacheLoader`, `cache/ManifestCacheValue`, `profile/IcebergMetricsReporter`. TIER-2 (blocked until `HMSExternalTable`/`IcebergDlaTable` metadata cutover): `IcebergUtils`, `IcebergExternalMetaCache`, `IcebergMetadataOps`, `IcebergSchemaCacheKey/Value`, `IcebergSnapshot(CacheValue)`, `IcebergPartition(Info)`, `IcebergTableCacheValue`, `IcebergManifestEntryKey`, `IcebergMvccSnapshot`, `DorisTypeToIcebergType`, `IcebergCatalogConstants`. +- **4 blockers**: `IcebergHMSSource` (dies with `IcebergScanNode`); `StatisticsUtil.getIcebergColumnStats` + `HMSExternalTable` ICEBERG stats branch (single-consumer, deletable with the retype); `datasource/systable/IcebergSysTable` (already a throwing dead-end — `createSysExternalTable` unconditionally throws; querying `$snapshots` on iceberg-on-HMS already fails today → no regression to defer). +- **Per-column stats SPI (OQ-COLSTATS)**: the fast-path is `HMSExternalTable.getColumnStatistic` case ICEBERG, gated by `enable_fetch_iceberg_stats` (**default OFF**); it feeds query-planning cache-miss, NOT ANALYZE (ANALYZE already degrades to SQL sampling with no iceberg branch). **Native iceberg already dropped this fast-path** (`PluginDrivenExternalTable` has no `getColumnStatistic` override → inherits `Optional.empty()`). Recommendation: **DROP** for iceberg-on-HMS (parity with native iceberg, default-off, coarse estimate anyway — min/max forced to ±INF, no NDV) rather than add a new per-column SPI method + neutral DTO. Table-level rowCount MUST still be provided via `getTableStatistics` (iceberg connector already computes it). Revisit at the retype. +- **`IcebergUtils` extraction (OQ-ICEBERGUTILS)**: the ONLY members the connector-agnostic engine needs to survive the 23-class deletion are **6**: constants `ICEBERG_ROW_ID_COL`, `ICEBERG_LAST_UPDATED_SEQUENCE_NUMBER_COL`, `ICEBERG_ROW_LINEAGE_MIN_VERSION`; methods `isIcebergRowLineageColumn(String)`, `isIcebergRowLineageColumn(Column)`; and `getEffectiveIcebergFormatVersion(Map,Map)`. Callers: `BindExpression:358`, `CreateTableInfo:1140,1144,1164,1166`, `IcebergMergeCommand:176,201,260,342-343,369`, `IcebergUpdateCommand:106` (+ tests `LogicalFileScanTest`, `PluginDrivenScanNodeClassifyColumnTest`). Extract these to a small **fe-core** SDK-free util (must be fe-core, not fe-common — the `Column` overload needs `org.apache.doris.catalog.Column`); `getEffectiveIcebergFormatVersion` needs its 3 iceberg string constants inlined as literals (`"table-override."`/`"table-default."`/`"format-version"`) to go SDK-free. NB: extraction only matters WHEN the 23 classes are deleted (flip). Also: even after the split, `StatisticsUtil` + `IcebergSysTable` remain independent SDK-leak sites → "fe-core fully iceberg-SDK-free" is a flip-scoped success criterion, not this step's. + +## Iron-rule guardrail (do not cheat reachability) +Do NOT add an `if(iceberg)`/`switch(dlaType)`/`instanceof HMSExternalTable` arm in `PhysicalPlanTranslator` to divert HMS-iceberg into `PluginDrivenScanNode`. The only correct lever is the table class (`instanceof PluginDrivenExternalTable`) + the gateway's `getScanPlanProvider(handle)` returning the iceberg provider for ICEBERG-format handles — which is exactly what the flip delivers. diff --git a/plan-doc/tasks/metacache-connector-port-tasklist.md b/plan-doc/tasks/metacache-connector-port-tasklist.md new file mode 100644 index 00000000000000..801b2144316e33 --- /dev/null +++ b/plan-doc/tasks/metacache-connector-port-tasklist.md @@ -0,0 +1,22 @@ +# Task list — port connector hand-rolled caches onto the copied cache framework + +Design: [designs/metacache-connector-port-design.md](./designs/metacache-connector-port-design.md) +Scope (user, 2026-07-01): iceberg + paimon together. + +- [x] **C1** — `fe-connector-cache` compile against Caffeine **2.9.3** (child-first per-plugin linkage; iceberg + runs 2.9.3).

`TrinoBootstrap` 是进程级单例，`getInstance()` 遇到不同 plugin dir 抛 `IllegalStateException`。而 §5 的第 3/4 步是**探测文件系统**决定的，即解析结果依赖探测时刻的磁盘状态： + +> catalog A 于 T1 建立 → `plugins/connectors/` 当时为空 → 解析到 `plugins/trino_plugins/` → 单例锁定。 +> 用户于 T2 照旧文档往 `plugins/connectors/` 丢了插件。 +> catalog B 于 T3 建立 → 解析到 `plugins/connectors/` → `getInstance()` 不一致 → 抛异常，catalog B 不可用。 + +这是今天就存在的隐患（两级 fallback 时窗口小），加到三级会放大。 + +**决策：把 fallback 探测结果按 `doris_home` memoize 一次，进程内所有 catalog 复用。** + +理由不是防御性编程，而是**它更诚实**：Trino 的插件只在 `TrinoBootstrap` 构造时加载一次，运行中往目录里丢新插件在 FE 重启前根本不生效。既然如此，解析时机就该与加载时机对齐；每个 catalog 重新探一次磁盘，制造的是"探测结果会变但加载结果不会变"的假象。memoize 后进程内必然一致，上述异常场景从"可能发生"变为结构上不可能。 + +实现用 `ConcurrentHashMap` 以 `dorisHome` 为 key（而非裸 static 字段）：生产环境 `doris_home` 恒定 → 只探一次；单测各用各的临时目录 → 天然隔离，无测试污染。 + +§5 的第 1、2

`legacyProbeIsMemoizedSoEveryCatalogInAProcessAgrees` 如期失败（第一次解析得 `plugins/trino_plugins`、第二次得 `plugins/connectors`，正是 §5.2 会触发 `IllegalStateException` 的分歧），其余 8 条不受影响。 + - 把 `Config.java` 默认值改成 `/plugins/drifted_name` → `feConfigDefaultMatchesThePluginsHardcodedDefault` 如期失败，其余 8 条不受影响。 +- `build.sh` 过 `bash -n`；`be-java-extensions/trino-connector-scanner` 编译 + checkstyle 通过。 + +**§10 第 3 条的落地结论**：`fe-connector-trino` 的 pom **确有** compile-scope 的 fe-common 依赖（为 `TrinoColumnMetadata` 引入），故按设计走"有则加断言测试"分支：`DEFAULT_PLUGIN_SUBDIR` 改为 package-private + `@VisibleForTesting`，测试双向断言它与 `Config.trino_connector_plugin_dir` 一致（改任一侧都会失败）。BE 的 `config.cpp` 是 Java 测试够不到的第三份副本，仍只靠三处交叉注释。 + +> **已被 §11 推翻**：该断言测试要 import `org.apache.doris.common.Config`，撞上 connector 导入门禁而挂 CI（build 997269）。现改为常量去重，漂移不再可能，断言测试已删。 + +**欠账**： + +1. **BE 未跑全量构建**。`config.cpp:1543` 仅改字符串字面量（既有 `DEFINE_String` 内），风险接近零，但严格说未经编译验证。 +2. **无 e2e**。三级 fallback 只有单测覆盖。真集群回归要跑到它需要构造"老部署遗留目录非空"的形态，而回归环境走的是显式配置（§6"不改"一节），天然绕开 fallback —— 即**现有回归跑绿不构成 fallback 的证据**。 +3. **需 release note**。默认值变更对用户可见：老部署靠 fallback 零感知，但新装的用户投放点从 `plugins/connectors/` 变为 `plugins/trino_plugins/`，文档（含 doris-website 的 trino-connector 安装说明）须同步。 + +## 9. 实现期的并发阻塞（已解除，留档） + +设计批准时探测到 `sh build.sh --be`（PID 1515583）正在跑，§6 的四个源文件全在其必经之路上 —— 含**正在被执行的 `build.sh` 本体**（`sh` 按字节偏移边读边执行，而 1271 行的 `mkdir` 位于 ninja 编完才走到的 BE 打包段，改动会令其从错位偏移读入新字节）。故当轮只写设计、代码一行未动，挂 Monitor 等该构建于 16:56:36 退出后才施改。留档理由：这是共享工作树上的复发型风险，下次改 `build.sh` 或 `be/src/` 前同样要先探。 + +## 10. 验收标准（原始定义，逐条结果见 §8） + +1. `TrinoBootstrapTest` 覆盖 §7 兼容矩阵全部 5 行，且每个 case 断言的是"为什么这样解析"而非仅"解析成了什么"。 +2. memoize 后，同一 `doris_home` 下两次 `resolvePluginDir()` 在中途改变磁盘状态时返回同一结果（§5.2 的回归锁）。 +3. §5.1 三处常量一致。实现时先确认 `fe-connector-trino` 的测试 classpath 上是否有 fe-common：**有**则加一个断言 `TrinoBootstrap` 的默认值字面量与 `Config.trino_connector_plugin_dir` 一致的测试；**没有**（该模块以零 fe-core 依赖为目标，fe-common 亦可能不在链上）则退回三处注释交叉指认，不硬造依赖来测。BE 侧跨进程无法断言，一律靠注释。 + > **已被 §11 推翻**：这条给的两个分支都错——它默认了"常量必须各存一份，只能事后检测漂移"。真正的第三条路是让 Java 侧共享同一个编译期常量，从源头消灭漂移。 +4. `build.sh --fe --be` 后 `output/{fe,be}/plugins/` 下有 `trino_plugins/`、无 `connectors/`。 + +## 11. 施工后修正：常量去重取代断言守门（CI 997269） + +§8 落地的"断言守门"方案在 CI 上挂了，本节记录推翻它的理由与替代方案。**§8 第 3 段与 §10 第 3 条已作废，以本节为准。** + +### 11.1 为什么原方案必然挂 + +`TrinoBootstrapTest` 为断言两侧一致，必须 `import org.apache.doris.common.Config`。而 `tools/check-connector-imports.sh` 禁止 fe-connector 模块引用 `org.apache.doris.(catalog|common|datasource|qe|...)`——**且它扫 `src/test/java`**。 + +时间线说明这不是巧合： + +| 日期 | 提交 | 内容 | +|---|---|---| +| 2026-07-12 | `40757d9e453` | 门禁"补 4 个漏洞"，其**第 3 个漏洞正是"只扫 src/main、漏了 src/test"**，并配 self-test 专门 seed 一个 test-source import 当违规样例 | +| 2026-07-15 | `5e9d9449767` | 本设计的断言测试落地，正好踩中该漏洞 | + +即门禁没坏（self-test 至今 PASS），是断言测试撞在门禁三天前刚堵上的洞里。**结论：不能改门禁迁就测试**——那等于把刚补的漏洞重新捅开。 + +### 11.2 原方案的思维盲区 + +§10 第 3 条把选择限定成"能测就加断言 / 不能测就靠注释"，二者都默认了**常量必须各存一份**。但插件读不到 `Config` 的是**运行时**（隔离 classloader），**编译期**完全读得到——`fe-connector-trino` 本就有 compile-scope 的 fe-common 依赖。于是存在第三条路：共享同一个编译期常量，漂移从"事后检测"变为"结构上不可能"。 + +### 11.3 替代方案 + +> **已被 §12 取代**：`TrinoPluginDirs` 已删除。放弃兼容后插件根本不需要默认值，共享常量失去存在意义。§11 的问题诊断仍成立，解法以 §12 为准。 + +新增 `fe-common` 的 `org.apache.doris.trinoconnector.TrinoPluginDirs.DEFAULT_PLUGIN_SUBDIR` 作为 Java 侧唯一真相，三个消费方共享： + +| 消费方 | 模块 | 取用方式 | +|---|---|---| +| `Config.trino_connector_plugin_dir` | fe-common | 同模块直接引用 | +| `TrinoBootstrap`（FE 插件） | fe-connector-trino | import（`org.apache.doris.trinoconnector` 不在门禁 FORBIDDEN 名单内） | +| `TrinoConnectorPluginLoader`（BE scanner） | be-java-extensions | 同包，无需 import | + +原设计说的"三处"实为**四处**——`TrinoConnectorPluginLoader` 那份第四拷贝当初被漏数了，此次一并收编。Java 3 份 → 1 份；`be/src/common/config.cpp` 仍是跨语言够不到的最后一份，继续靠注释交叉指认。 + +**为什么隔离 classloader 下安全**：`org.apache.doris.trinoconnector` 本就是插件运行时够得到的包，无需任何特殊论证—— + +- `fe-common` 是 `fe-connector-trino` 的 compile-scope 依赖，**被打进插件 zip 的 `lib/fe-common-*.jar`**（实测该 jar 内含 `org/apache/doris/trinoconnector/`）。 +- `ConnectorPluginManager.CONNECTOR_PARENT_FIRST_PREFIXES` 只有 `org.apache.doris.connector.` 与 `org.apache.doris.filesystem.`，`org.apache.doris.trinoconnector.` **不在其中** → 走 child-first → 插件从自己捆绑的那份加载。 +- 铁证：`TrinoScanPlanProvider.java:300` 早已 `new TrinoColumnMetadata(...)`，即插件在运行时真实实例化同包的 fe-common 类。 + +> **反面留档（施工中一度写错，经对抗 review 揪出）**：初版注释与本节曾声称"插件从隔离 classloader **够不到** `TrinoPluginDirs`，全靠编译期常量内联才安全"。**这是错的**。内联确实发生（`javap -v` 实证：`TrinoBootstrap.class`/`Config.class` 常量池含内联字面量、对 `TrinoPluginDirs` 符号引用数为 0；`TrinoConnectorPluginLoader.class` 因 target major 52 多留一个无指令引用的 `CONSTANT_Class` 条目，按 JVMS §5.4.3 惰性解析永不解析），但它**不是安全性的成因**——即便不内联，child-first 也照样能加载。把"我们不需要"写成"我们做不到"会误导后人以为某些去重在结构上不可能。 + +**为什么 legacy 目录列表不一起收编**：纯粹是本次改动范围的边界，**不是技术上做不到**。`LEGACY_PLUGIN_SUBDIRS`（`{"/connectors", "/plugins/connectors"}`）在 `TrinoBootstrap` 与 `TrinoConnectorPluginLoader` 各存一份、无守门，属**遗留的既有重复**，与本次 CI 故障无关，故不在此顺手动。**留作已知欠账**（见 §11.5）：若哪天要收编，把它挪进 `TrinoPluginDirs` 是可行的，代价只是插件多一个真实运行时引用（与既有的 `TrinoColumnMetadata` 同性质）。 + +### 11.4 代价与验证 + +代价：删掉 `feConfigDefaultMatchesThePluginsHardcodedDefault()`（漂移已不可能，断言退化为同义反复）。`TrinoBootstrapTest` 从 9 case 变 8 case，§7 兼容矩阵五行覆盖不变。 + +验证：门禁 exit 0 且 self-test 仍 PASS；fe-common / fe-connector-trino / trino-connector-scanner 三模块编译 + checkstyle 0 violations；`TrinoBootstrapTest` 8 run / 0 fail / 0 skip；全仓 `trino_connector_plugin_dir` 引用（regression 与 samples 的 fe.conf/be.conf）**全部显式设值**，走"显式覆盖"分支，不受默认值来源变更影响，行为零变化。 + +§8 三条欠账（BE 未全量构建、无 e2e、需 release note）不受本次修正影响，依旧成立。 + +### 11.5 本次遗留的已知欠账 + +1. **`LEGACY_PLUGIN_SUBDIRS` 仍是两份无守门的重复**（`TrinoBootstrap.java` 与 `TrinoConnectorPluginLoader.java`，值均为 `{"/connectors", "/plugins/connectors"}`）。漂移后果：FE 与 BE 回退到不同的遗留目录。属既有问题，本次未动（见 §11.3 末）。 +2. **`build.sh` 另有两处 `plugins/trino_plugins/` 字面量**（约 1049 / 1276 行，创建投放目录用），未纳入交叉注释网。它们只决定"建哪个空目录"，与"判断用户是否显式设过"的语义链无关，漂移不会误判配置，但全新安装的投放点会与默认解析结果不一致。 + +## 12. 方案再定：放弃兼容，解析链砍到两步（2026-07-16 用户拍板） + +**本节推翻 §3 的 C1、§5 的解析链、§7 的兼容矩阵，以及 §11 的常量去重方案。** §11 记录的问题诊断仍然成立，但它的解法已被更简单的方案取代。 + +### 12.1 决策 + +用户明确：**FE 与 BE 都不再考虑任何兼容**。只识别两个来源： + +``` +1. catalog 属性 trino.plugin.dir 非空 → 用它 +2. 否则 → trino_connector_plugin_dir 配置值，逐字使用 + （默认 DORIS_HOME/plugins/trino_plugins） +``` + +§5 原链的第 3、4 步（探测 `DORIS_HOME/connectors` 与 `DORIS_HOME/plugins/connectors`）**全部删除**，FE、BE 两侧同步删。 + +### 12.2 连锁反应：默认值常量整体消失 + +这不只是删掉两个 if。**"判断用户是否显式设过"这个语义整体没了**——原第 2 步要靠"配置值 ≠ 默认值"反推用户意图，而这个反推唯一的用途就是决定要不要走第 3、4 步的兼容兜底。兜底既然不存在，反推就没有消费者。 + +于是 §5.1 那个"隐蔽同步点"从根上蒸发： + +| 原先 | 现在 | +|---|---| +| 4 处默认值字面量必须同步，漂移会静默误判 | 插件与 scanner **完全不需要知道默认值**，各自逐字使用传入的配置值 | +| `TrinoPluginDirs`（§11 引入的共享常量） | **删除**——只剩 `Config.java` 与 `config.cpp` 各持一份普通配置默认值，不参与任何推断 | +| `Config` 依赖 `org.apache.doris.trinoconnector` | **解除**——`Config` 回到纯字面量，不再依赖 trino | + +`Config.java` 与 `config.cpp` 两份默认值仍需一致，但耦合强度已完全不同：它只是"FE 和 BE 该去同一个地方找插件"这种普通的 FE/BE 配置对齐，漂移的后果是直白的加载不到，**不再有"把没设过误判成设过"这种静默错判**。 + +### 12.3 顺带消失的复杂度 + +- `LEGACY_PLUGIN_SUBDIRS`（FE + BE 各一份，§11.5 记的第 1 条欠账）——**随兜底一起删除，该欠账关闭**。 +- `probeLegacyDirs()` / `isNonEmptyDir()`（FE）、`checkAndReturnPluginDir()` 的探测分支（BE）——删除。 +- `RESOLVED_DEFAULT_DIRS` 的 memoize 与 §5.2 那一整节的分析——**删除**。memoize 的存在理由是"探测读文件系统，答案会随磁盘状态变化，而单例 fail-loud 受不了答案漂移"。现在 `resolvePluginDir()` 是入参 `(properties, environment)` 的纯函数，不碰文件系统，§5.2 描述的 `IllegalStateException` 场景从"靠 memoize 压住"变成结构上不可能。 +- `TrinoBootstrap` 不再需要 env 里的 `doris_home`（仅日志路径仍用 `System.getenv("DORIS_HOME")`，与解析无关）。 + +### 12.4 fail-loud 的取舍 + +`DefaultConnectorContext:563` 无条件 `env.put("trino_connector_plugin_dir", Config.trino_connector_plugin_dir)`，而 `Config` 的该字段恒有值，故 env 里缺这个 key 只可能是引擎侧的 bug。此时**抛 `IllegalStateException`**，而不是猜一个目录：猜错的表现是"catalog 建得出来但每个查询都失败"，排查代价极高；抛在解析点则原因就在现场。 + +### 12.5 用户可见的破坏性变更（必须写 release note） + +**这是本设计里唯一一处真正的破坏性变更，且失败是静默的。** + +已发布版本（2.1.8 起）的默认投放点是 `DORIS_HOME/plugins/connectors`。升级到本改动后： + +| 部署形态 | 升级后行为 |

fe.conf/be.conf 显式设了 `trino_connector_plugin_dir` | 行为不变（含回归环境，见 §6"不改"一节） | +| 全新安装 | 行为不变，投放到 `plugins/trino_plugins/` | + +**操作者需二选一**：把插件移到 `plugins/trino_plugins/`，或把 `trino_connector_plugin_dir` 指到现有目录。FE 与 BE 两侧都要做。 + +### 12.6 验证 + +- 门禁 exit 0；`Config.java` 已无任何 trino import（本轮三条要求之一）。 +- fe-common / fe-connector-trino / trino-connector-scanner 三模块编译 + checkstyle 通过（`-Dmaven.build.cache.enabled=false` 强制真跑，避免 build cache 静默跳过）。 +- `TrinoBootstrapTest` 重写为 4 case、全绿 0 skip：属性优先、配置逐字生效、**legacy 目录即使有插件也不被理会**、env 缺 key 则 fail-loud。 +- **变异测试**（证明回归锁咬得住）：把 legacy 兜底加回 `resolvePluginDir()` → `legacyPluginDirsAreNotConsultedEvenWhenTheyHoldPlugins` 如期变红（`expected: .../plugins/trino_plugins but was: .../plugins/connectors`），其余 3 条不受影响；还原后复绿。 + +### 12.7
