Sorry I just looked even closer, I now think the actual best place for this log is probably in ComplexColumnPartSerde, in the getDeserializer method if serde is null. This way you can include the 'typeName' of the missing type, which isn't available in SimpleColumnHolder, my bad.

Ah, yes. Would the better place to log this warning be then in the constructor itself since that is the first place where serde gets set to null?

Either place seems fine to me

I think this is going to fail Travis for unused import

oh no! I just pushed a commit to remove the import.

(#9877) * Number based columns representing time in custom format cannot be used as timestamp column in Druid. Prior to this fix, if an integer column in parquet is storing dateint in format yyyyMMdd, it cannot be used as timestamp column in Druid as the timestamp parser interprets it as a number storing UTC time instead of treating it as a number representing time in yyyyMMdd format.

Another patch should follow this one so that the query path uses the correlation object instead of it's underlying maps. * Optimize join queries where filter matches nothing Fixes #9787 This PR changes the Joinable interface to return an Optional set of correlated values for a column. This allows the JoinFilterAnalyzer to differentiate between the case where the column has no matching values and when the column could not find matching values. This PR chose not to distinguish between cases where correlated values could not be computed because of a config that has this behavior disabled or because of user error - like a column that could not be found.

Our own implementation had a bug which did not fail the future if the applied function threw an exception, resulting in the future never completing. An attempt was made to fix this bug, however when running againts Guava's own tests, our version failed another half dozen tests, so it was decided to not continue down that path and scrap our own implementation. Explanation for how was this bug manifested itself: An exception thrown in BaseAppenderatorDriver.publishInBackground when invoked via transformAsync in StreamAppenderatorDriver.publish will cause the resulting future to never complete. This explains why when encountering https://github.com/apache/druid/issues/9845 the task will never complete, forever waiting for the publishFuture to register the handoff. As a result, the corresponding "Error while publishing segments ..." message only gets logged once the index task times out and is forcefully shutdown when the future is force-cancelled by the executor. * Document unsupported Join on multi-value column (#9948) * Document Unsupported Join on multi-value column * Document Unsupported Join on multi-value column * address comments * Add unit tests * address comments * add tests * Add REGEXP_LIKE, fix bugs in REGEXP_EXTRACT.

Druid will only accept http requests with the method: GET, PUT, POST, DELETE and OPTIONS. If a Druid admin wants to allow other methods, they can do so by using the ServerConfig#allowedHttpMethods config. If a Druid user would like to disallow OPTIONS, this can be done by changing the AuthConfig#allowUnauthenticatedHttpOptions config * Exclude OPTIONS from always supported HTTP methods Add HEAD as an allowed method for web console e2e tests * fix docs * fix security IT * Actually fix the web console e2e tests * Ignore icode coverage for nitialization classes * code review * Move shardSpec tests to core (#10079) * Move shardSpec tests to core * checkstyle * inject object mapper for testing * unused import * Fix native batch range partition segment sizing (#10089) * Fix native batch range partition segment sizing Fixes #10057. Native batch range partitioning was only considering the partition dimension value when grouping rows instead of using all of the row's partition values. Thus, for schemas with multiple dimensions, the rollup was overestimated, which would cause too many dimension values to be packed into the same range partition. The resulting segments would then be overly large (and not honor the target or max partition sizes). Main changes: - PartialDimensionDistributionTask: Consider all dimension values when grouping row - RangePartitionMultiPhaseParallelIndexingTest: Regression test by having input with rows that should roll up and rows that should not roll up * Use hadoop & native hash ingestion row group key * Fix nullhandling exception (#10095) Co-authored-by: Atul Mohan <atulmohan@yahoo-inc.com> * Make 0.19 brokers compatible with 0.18 router (#10091) * Make brokers backwards compatible In 0.19, Brokers gained the ability to serve segments. To support this change, a `BROKER` ServerType was added to `druid.server.coordination`. Druid nodes prior to this change do not know of this new server type and so they would fail to deserialize this node's announcement. This change makes it so that the broker only announces itself if the segment cache is configured on the broker. It is expected that a Druid admin will only configure the segment cache on the broker once the cluster has been upgraded to a version that supports a broker using the segment cache. * make code nicer * Add tests * Ignore icode coverage for nitialization classes * Revert "Ignore icode coverage for nitialization classes" This reverts commit aeec0c2ac2b07c1b9262e32201913c7194167271. * code review * Correct the position of the double quotation in distinctcount.md file (#10094) ``` "dimensions": "[sample_dim]" ``` should be ``` "dimensions": ["sample_dim"] ``` * QueryCountStatsMonitor can be injected in the Peon (#10092) * QueryCountStatsMonitor can be injected in the Peon This change fixes a dependency injection bug where there is a circular dependency on getting the MonitorScheduler when a user configures the QueryCountStatsMonitor to be used. * fix tests * Actually fix the tests this time * Information schema doc update (#10081) * add docs for IS_JOINABLE and IS_BROADCAST to INFORMATION_SCHEMA docs * fixes * oops * revert noise * missed one * spellbot * Remove payload field from table sys.segment (#9883) * remove payload field from table sys.segments * update doc * fix test * fix CI failure * add necessary fields * fix doc * fix comment * Web console: allow link overrides for docs, and more (#10100) * link overrides * change doc version * fix snapshots * Enabling Static Imports for Unit Testing DSLs (#331) (#9764) * Enabling Static Imports for Unit Testing DSLs (#331) Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Feature 8885 - Enabling Static Imports for Unit Testing DSLs (#435) * Enabling Static Imports for Unit Testing DSLs * Using suppressions checkstyle to allow static imports only in the UTs Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Removing the changes in the checkstyle because those are not needed Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Prevent unknown complex types from breaking DruidSchema refresh (#9422) * Update web address to datasketches.apache.org (#10096) * Join filter pre-analysis simplifications and sanity checks.

Previously, pre-analyses were computed for multiple levels of the query, some of which were unnecessary. - Remove JoinFilterPreAnalysisGroup and join query level gathering code, since they existed to support precomputation of multiple pre-analyses. - Embed JoinFilterPreAnalysisKey into JoinFilterPreAnalysis and use it to sanity check at processing time that the correct pre-analysis was done. Tangentially related changes: - Remove prioritizeAndLaneQuery functionality from LocalQuerySegmentWalker. The computed priority and lanes were not being used. - Add "getBaseQuery" method to DataSourceAnalysis to support identification of the proper subquery for filter pre-analysis. * Fix compilation errors. * Adjust tests. * Filter on metrics doc (#10087) * add note about filter on metrics to filter docs * edit doc to include having and filtered aggregator links * Fix UnknownTypeComplexColumn#makeVectorObjectSelector * Fix RetryQueryRunner to actually do the job (#10082) * Fix RetryQueryRunner to actually do the job * more javadoc * fix test and checkstyle * don't combine for testing * address comments * fix unit tests * always initialize response context in cachingClusteredClient * fix subquery * address comments * fix test * query id for builders * make queryId optional in the builders and ClusterQueryResult * fix test * suppress tests and unused methods * exclude groupBy builder * fix jacoco exclusion * add tests for builders * address comments * don't truncate * Closing yielder from ParallelMergeCombiningSequence should trigger cancellation (#10117) * cancel parallel merge combine sequence on yielder close * finish incomplete comment * Update core/src/test/java/org/apache/druid/java/util/common/guava/ParallelMergeCombiningSequenceTest.java Fixes checkstyle Co-authored-by: Jihoon Son <jihoonson@apache.org> * Revert "Fix UnknownTypeComplexColumn#makeVectorObjectSelector" (#10121) This reverts commit 7bb7489afc7a2cc496be93ae69681b6ab13a7c66. * update links datasketches.github.io to datasketches.apache.org (#10107) * update links datasketches.github.io to datasketches.apache.org * now with more apache * oops * oops * Fix Stack overflow with infinite loop in ReduceExpressionsRule of HepProgram (#10120) * Fix Stack overflow with SELECT ARRAY ['Hello', NULL] * address comments * fixes for ranger docs (#10109) * Fix UnknownComplexTypeColumn#makeVectorObjectSelector.

Druid will only accept http requests with the method: GET, PUT, POST, DELETE and OPTIONS. If a Druid admin wants to allow other methods, they can do so by using the ServerConfig#allowedHttpMethods config. If a Druid user would like to disallow OPTIONS, this can be done by changing the AuthConfig#allowUnauthenticatedHttpOptions config * Exclude OPTIONS from always supported HTTP methods Add HEAD as an allowed method for web console e2e tests * fix docs * fix security IT * Actually fix the web console e2e tests * Ignore icode coverage for nitialization classes * code review * Move shardSpec tests to core (#10079) * Move shardSpec tests to core * checkstyle * inject object mapper for testing * unused import * Fix native batch range partition segment sizing (#10089) * Fix native batch range partition segment sizing Fixes #10057. Native batch range partitioning was only considering the partition dimension value when grouping rows instead of using all of the row's partition values. Thus, for schemas with multiple dimensions, the rollup was overestimated, which would cause too many dimension values to be packed into the same range partition. The resulting segments would then be overly large (and not honor the target or max partition sizes). Main changes: - PartialDimensionDistributionTask: Consider all dimension values when grouping row - RangePartitionMultiPhaseParallelIndexingTest: Regression test by having input with rows that should roll up and rows that should not roll up * Use hadoop & native hash ingestion row group key * Fix nullhandling exception (#10095) Co-authored-by: Atul Mohan <atulmohan@yahoo-inc.com> * Make 0.19 brokers compatible with 0.18 router (#10091) * Make brokers backwards compatible In 0.19, Brokers gained the ability to serve segments. To support this change, a `BROKER` ServerType was added to `druid.server.coordination`. Druid nodes prior to this change do not know of this new server type and so they would fail to deserialize this node's announcement. This change makes it so that the broker only announces itself if the segment cache is configured on the broker. It is expected that a Druid admin will only configure the segment cache on the broker once the cluster has been upgraded to a version that supports a broker using the segment cache. * make code nicer * Add tests * Ignore icode coverage for nitialization classes * Revert "Ignore icode coverage for nitialization classes" This reverts commit aeec0c2ac2b07c1b9262e32201913c7194167271. * code review * Correct the position of the double quotation in distinctcount.md file (#10094) ``` "dimensions": "[sample_dim]" ``` should be ``` "dimensions": ["sample_dim"] ``` * QueryCountStatsMonitor can be injected in the Peon (#10092) * QueryCountStatsMonitor can be injected in the Peon This change fixes a dependency injection bug where there is a circular dependency on getting the MonitorScheduler when a user configures the QueryCountStatsMonitor to be used. * fix tests * Actually fix the tests this time * Information schema doc update (#10081) * add docs for IS_JOINABLE and IS_BROADCAST to INFORMATION_SCHEMA docs * fixes * oops * revert noise * missed one * spellbot * Remove payload field from table sys.segment (#9883) * remove payload field from table sys.segments * update doc * fix test * fix CI failure * add necessary fields * fix doc * fix comment * Web console: allow link overrides for docs, and more (#10100) * link overrides * change doc version * fix snapshots * Enabling Static Imports for Unit Testing DSLs (#331) (#9764) * Enabling Static Imports for Unit Testing DSLs (#331) Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Feature 8885 - Enabling Static Imports for Unit Testing DSLs (#435) * Enabling Static Imports for Unit Testing DSLs * Using suppressions checkstyle to allow static imports only in the UTs Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Removing the changes in the checkstyle because those are not needed Co-authored-by: mohammadshoaib <mohammadshoaib@miqdigital.com> * Prevent unknown complex types from breaking DruidSchema refresh (#9422) * Update web address to datasketches.apache.org (#10096) * Join filter pre-analysis simplifications and sanity checks. (#10104) * Join filter pre-analysis simplifications and sanity checks. - At pre-analysis time, only compute pre-analysis for the innermost root query, since this is the one that will run on the join that involves the base datasource. Previously, pre-analyses were computed for multiple levels of the query, some of which were unnecessary. - Remove JoinFilterPreAnalysisGroup and join query level gathering code, since they existed to support precomputation of multiple pre-analyses. - Embed JoinFilterPreAnalysisKey into JoinFilterPreAnalysis and use it to sanity check at processing time that the correct pre-analysis was done. Tangentially related changes: - Remove prioritizeAndLaneQuery functionality from LocalQuerySegmentWalker. The computed priority and lanes were not being used. - Add "getBaseQuery" method to DataSourceAnalysis to support identification of the proper subquery for filter pre-analysis. * Fix compilation errors. * Adjust tests. * Filter on metrics doc (#10087) * add note about filter on metrics to filter docs * edit doc to include having and filtered aggregator links * Fix UnknownTypeComplexColumn#makeVectorObjectSelector * Fix RetryQueryRunner to actually do the job (#10082) * Fix RetryQueryRunner to actually do the job * more javadoc * fix test and checkstyle * don't combine for testing * address comments * fix unit tests * always initialize response context in cachingClusteredClient * fix subquery * address comments * fix test * query id for builders * make queryId optional in the builders and ClusterQueryResult * fix test * suppress tests and unused methods * exclude groupBy builder * fix jacoco exclusion * add tests for builders * address comments * don't truncate * Closing yielder from ParallelMergeCombiningSequence should trigger cancellation (#10117) * cancel parallel merge combine sequence on yielder close * finish incomplete comment * Update core/src/test/java/org/apache/druid/java/util/common/guava/ParallelMergeCombiningSequenceTest.java Fixes checkstyle Co-authored-by: Jihoon Son <jihoonson@apache.org> * Revert "Fix UnknownTypeComplexColumn#makeVectorObjectSelector" (#10121) This reverts commit 7bb7489afc7a2cc496be93ae69681b6ab13a7c66. * update links datasketches.github.io to datasketches.apache.org (#10107) * update links datasketches.github.io to datasketches.apache.org * now with more apache * oops * oops * Fix Stack overflow with infinite loop in ReduceExpressionsRule of HepProgram (#10120) * Fix Stack overflow with SELECT ARRAY ['Hello', NULL] * address comments * fixes for ranger docs (#10109) * Fix UnknownComplexTypeColumn#makeVectorObjectSelector.

(#10279) * Add SQL "OFFSET" clause. Under the hood, this uses the new offset features from #10233 (Scan) and #10235 (GroupBy). Since Timeseries and TopN queries do not currently have an offset feature, SQL planning will switch from one of those to Scan or GroupBy if users add an OFFSET. Includes a refactoring to harmonize offset and limit planning using an OffsetLimit wrapper class. This is useful because it ensures that the various places that need to deal with offset and limit collapsing all behave the same way, using its "andThen" method. * Fix test and add another test. * introduce interning of internal files names in SmooshedFileMapper (#10295) * Redis cache extension enhancement (#10240) * support redis cluster * add 'password', 'database' properties * test cases passed * update doc * some improvements * fix CI * add more test cases to improve branch coverage * fix dependency check for test * resolve review comments * Optimize large InDimFilters (#10312) * Optimize large InDimFilters For large InDimFilters, in default mode, the filter does a linear check of the set to see if it contains either an empty or null. If it does, the empties are converted to nulls by passing through the entire list again. Instead of this, in default mode, we attempt to remove an empty string from the values that are passed to the InDimFilter. If an empty string was removed, we add null to the set * code review * Revert "code review" This reverts commit 61fe33ebf762764bb89108ddd966937f3313be71. * code review - less brittle * ExpressionFilter: Use index for expressions of single multi-value columns. (#10320) Previously, this was disallowed, because expressions treated multi-values as nulls. But now, if there's a single multi-value column that can be mapped over, it's okay to use the index. Expression selectors already do this. * Clarify SQL behavior for multi-value dimensions. (#10276) There are some known inconsistencies between SQL and native that users should be aware of. * Remove NUMERIC_HASHING_THRESHOLD (#10313) * Make NUMERIC_HASHING_THRESHOLD configurable Change the default numeric hashing threshold to 1 and make it configurable. Benchmarks attached to this PR show that binary searches are not more faster than doing a set contains check. The attached flamegraph shows the amount of time a query spent in the binary search. Given the benchmarks, we can expect to see roughly a 2x speed up in this part of the query which works out to ~ a 10% faster query in this instance. * Remove NUMERIC_HASHING_THRESHOLD * Remove stale docs * refactor internal type system (#9638) * better type tracking: add typed postaggs, finalized types for agg factories * more javadoc * adjustments * transition to getTypeName to be used exclusively for complex types * remove unused fn * adjust * more better * rename getTypeName to getComplexTypeName * setup expression post agg for type inference existing * more javadocs * fixup * oops * more test * more test * more comments/javadoc * nulls * explicitly handle only numeric and complex aggregators for incremental index * checkstyle * more tests * adjust * more tests to showcase difference in behavior * timeseries longsum array * Handle internal kinesis sequence numbers when reporting lag (#10315) * Handle internal kinesis sequence numbers when reporting lag * add unit test * Adding supported compression formats for native batch ingestion (#10306) * Adding supported compression formats for native batch ingestion * Update docs/ingestion/native-batch.md Co-authored-by: sthetland <steve.hetland@imply.io> * fix spellcheck Co-authored-by: Suneet Saldanha <suneet@apache.org> Co-authored-by: sthetland <steve.hetland@imply.io> * Add support for all partitioing schemes for auto compaction (#10307) * Add support for all partitioing schemes for auto compaction * annotate last compaction state for multi phase parallel indexing * fix build and tests * test * better home * Fix handling of 'join' on top of 'union' datasources. (#10318) * Fix handling of 'join' on top of 'union' datasources. The problem is that unions are typically rewritten into a series of individual queries on the underlying tables, but this isn't done when the union is wrapped in a join. The main changes are in UnionQueryRunner: 1) Replace an instanceof UnionQueryRunner check with DataSourceAnalysis. 2) Replace a "query.withDataSource" call with a new function, "Queries.withBaseDataSource". Together, these enable UnionQueryRunner to "see through" a join. * Tests. * Adjust heap sizes for integration tests. * Different approach, more tests. * Tweak. * Styling. * Move tools for indexing to TaskToolbox instead of injecting them in constructor (#10308) * Move tools for indexing to TaskToolbox instead of injecting them in constructor * oops, other changes * fix test * unnecessary new file * fix test * fix build * SQL support for union datasources. (#10324) * SQL support for union datasources. Exposed via the "UNION ALL" operator. This means that there are now two different implementations of UNION ALL: one at the top level of a query that works by concatenating subquery results, and one at the table level that works by creating a UnionDataSource. The SQL documentation is updated to discuss these two use cases and how they behave. Future work could unify these by building support for a native datasource that represents the union of multiple subqueries. (Today, UnionDataSource can only represent the union of tables, not subqueries.) * Fixes. * Error message for sanity check. * Additional test fixes. * Add some error messages. * Remove implied profanity from error messages.

Only the github `README.md` has been updated, not the `README.template` used for src and bin packages because presumably if you are reading from either of those you are just going to run locally and so the local quickstart is appropriate. * optimize announceHistoricalSegments (#9935) * optimize announceHistoricalSegment * optimize announceHistoricalSegment * revert offline SegmentTransactionalInsertAction uses a separate lock * optimize segmentExistsBatch: Avoid too many elements in the in condition * add unit test && Modified according to cr Co-authored-by: xiangqiao <xiangqiao@kuaishou.com> * Fix VARIANCE aggregator comparator (#10340) * Fix VARIANCE aggregator comparator The comparator for the variance aggregator used to compare values using the count.

Unlike the `Datasource` input, the `Interval` input did not have a blue outline to indicate that it was required as the `IntervalInput` component did not support an `intent` property. * Compaction config UI optional numShards (#10446) * Compaction config UI optional numShards Specifying `numShards` for hashed partitions is no longer required after https://github.com/apache/druid/pull/10419. Update the UI to make `numShards` an optional field for hash partitions. * Update snapshot * add vectorizeVirtualColumns query context parameter (#10432) * add vectorizeVirtualColumns query context parameter * oops * spelling * default to false, more docs * fix test * fix spelling * Remove Expr.visit.

(#10430) * RowBasedIndexedTable: Add specialized index types for long keys. Two new index types are added: 1) Use an int-array-based index in cases where the difference between the min and max values isn't too large, and keys are unique. 2) Use a Long2ObjectOpenHashMap (instead of the prior Java HashMap) in all other cases. In addition: 1) RowBasedIndexBuilder, a new class, is responsible for picking which index implementation to use. 2) The IndexedTable.Index interface is extended to support using unboxed primitives in the unique-long-keys case, and callers are updated to use the new functionality. Other key types continue to use indexes backed by Java HashMaps. * Fixup logic. * Add tests. * vectorize constant expressions with optimized selectors (#10440) * Web console: switch to switches instead of checkboxes (#10454) * switch to switches * add img alt * add relative * change icons * update snapshot * Fix the offset setting in GoogleStorage#get (#10449) * Fix the offset in get of GCP object * upgrade compute dependency * fix version * review comments * missed * Fix the task id creation in CompactionTask (#10445) * Fix the task id creation in CompactionTask * review comments * Ignore test for range partitioning and segment lock * Web console reindexing E2E test (#10453) Add an E2E test for the web console workflow of reindexing a Druid datasource to change the secondary partitioning type. The new test changes dynamic to single dim partitions since the autocompaction test already does dynamic to hashed partitions. Also, run the web console E2E tests in parallel to reduce CI time and change naming convention for test datasources to make it easier to map them to the corresponding test run. Main changes: 1) web-consolee2e-tests/reindexing.spec.ts - new E2E test 2) web-console/e2e-tests/component/load-data/data-connector/reindex.ts - new data loader connector for druid input source 3) web-console/e2e-tests/component/load-data/config/partition.ts - move partition spec definitions from compaction.ts - add new single dim partition spec definition * Fix UI datasources view edit action compaction (#10459) Restore the web console's ability to view a datasource's compaction configuration via the "action" menu. Refactoring done in https://github.com/apache/druid/pull/10438 introduced a regression that always caused the default compaction configuration to be shown via the "action" menu instead. Regression test is added in e2e-tests/auto-compaction.spec.ts. * Allow using jsonpath predicates with AvroFlattener (#10330) * Improve UI E2E test usability (#10466) - Update playwright to latest version - Provide environment variable to disable/enable headless mode - Allow running E2E tests against any druid cluster running on standard ports (tutorial-batch.spec.ts now uses an absolute instead of relative path for the input data) - Provide environment variable to change target web console port - Druid setup does not need to download zookeeper * Web console: fix lookup edit dialog version setting (#10461) * fix lookup edit dialog * update snapshots * clean up test * fix array types from escaping into wider query engine (#10460) * fix array types from escaping into wider query engine * oops * adjust * fix lgtm * Update version to 0.21.0-SNAPSHOT (#10450) * [maven-release-plugin] prepare release druid-0.21.0 * [maven-release-plugin] prepare for next development iteration * Update web-console versions * Test UI to trigger auto compaction (#10469) In the web console E2E tests, Use the new UI to trigger auto compaction instead of calling the REST API directly so that the UI is covered by tests. * adjustments to Kafka integration tests to allow running against Azure Event Hubs streams (#10463) * adjustments to kafka integration tests to allow running against azure event hubs in kafka mode * oops * make better * more better * vectorized group by support for nullable numeric columns (#10441) * vectorized group by support for numeric null columns * revert unintended change * adjust * review stuffs * Close aggregators in HashVectorGrouper.close() (#10452) * Close aggregators in HashVectorGrouper.close() * reuse grouper * Add missing dependency * Web console: Don't include realtime segments in size calculations.
