QuantaStream 0.1.3

QuantaStream 0.1.3

QuantaStream 0.1.3 makes the path from discovery to a useful evaluation
coherent, whether you arrive from the website, GitHub repository, a release
post, or an already-extracted bundle.

Choose the evaluation that fits

• Run a first query: download the Linux/AMD64 bundle, restore the included
  TPC-H sample, run the local doctor, and query it through a MySQL-compatible
  client.
• Migrate a small MySQL model: use qstream-migrate to analyze a bounded
  table set, review generated mappings, load the data, and validate row counts.
• Connect Tableau: use Tableau's Other Databases (JDBC) connector with
  MySQL Connector/J and evaluate a curated analytical view.

Start at Evaluate QuantaStream 0.1.3.

Self-contained onboarding

The binary Getting Started
guide no longer assumes that another page performed the download first. It now
covers, in order:

1. prerequisites;
2. release download;
3. checksum verification and unpacking;
4. bundled sample restore;
5. engine startup;
6. local health checks;
7. first queries and shutdown.

The same guide also has a clear shortcut for users reading it from inside an
already-extracted bundle. WSL users are advised to unpack inside the Linux
filesystem to avoid slow extraction on /mnt/c.

The repository README now routes users by intent and leaves the executable
installation sequence in one canonical guide instead of duplicating commands.

Validation

• Passed go test ./... -count=1 -timeout=2m.
• Verified archive and packaged binary checksums.
• Verified that the bundled guide contains the complete ordered journey and
  the already-extracted-bundle branch.
• Passed the complete packaged smoke: bundled sample restore and query,
  fail-closed authentication checks, static credential and access-policy
  enforcement, loader ingest, doctor, WAL inspection, quiescent backup,
  validation, restore, support bundle, and restored-row query.

QuantaStream 0.1.2

QuantaStream 0.1.2

QuantaStream 0.1.2 is the recommended release for evaluating bitmap-native
analytics through familiar SQL and BI workflows. The Linux/AMD64 bundle offers
a short path to a first query, the MySQL migration workbench has been exercised
against Sakila, Superstore, and a seven-table FoodMart star, and Tableau users
can connect through the documented JDBC path and curated analytical views.

Three ways to evaluate

• Run a first query: restore the bundled TPC-H sample, run the local doctor,
  and query it through a MySQL-compatible client.
• Try your own MySQL model: use qstream-migrate to analyze a bounded table
  set, review generated mappings, load JSONL, and validate row counts.
• Connect Tableau: use Tableau's Other Databases (JDBC) connector with MySQL
  Connector/J, then evaluate a curated QuantaStream view in a worksheet or
  extract.

Start with the
evaluation guide
or the copy-paste
getting-started runbook.

Safer, clearer startup

• An omitted MySQL auth mode now fails startup with actionable guidance.
• Local evaluation must explicitly select --auth-mode permissive.
• Permissive authentication is rejected on non-loopback MySQL bind addresses.
• Networked operation must use --auth-mode static with configured credentials
  or a static account file.
• The single-node and distributed proxy entry points enforce the same behavior.
• The standard and distributed startup scripts require an explicit auth mode.

Permissive mode accepts every syntactically valid MySQL handshake. It is only
for an isolated loopback evaluation and is not a security boundary.

Authentication and SQL authorization remain separate. Static authentication
verifies identity, but authorization remains permissive unless an access-policy
file is configured. Consult the deployment guide before any shared or networked
use.

Onboarding and packaging

• Updated Getting Started, Quickstart, loader, development, deployment, and
  evaluation guidance to make the local permissive choice explicit.
• Updated the distributed proxy launcher to pass static auth and access-policy
  configuration through to the proxy binary.
• Updated the recommended download snippets for 0.1.2.

Validation

• Passed go test ./... -count=1 -timeout=2m.
• Verified archive, manifest, and binary checksums.
• Verified embedded version and source identity for commit 13ec26d4b695.
• The packaged end-to-end smoke proved:
  • omitted authentication is rejected;
  • network-bound permissive authentication is rejected;
  • explicit loopback permissive mode runs the bundled TPC-H sample;
  • static authentication accepts valid credentials and rejects an incorrect
    password;
  • access policy allows the reader and denies the blocked user;
  • loader ingest, doctor, WAL inspection, quiescent backup, validation,
    restore, support bundle, and restored-row query all pass.

QuantaStream 0.1.1

QuantaStream 0.1.1

QuantaStream 0.1.1 delivers initial Tableau support, a stronger single-node
experience, safer durability behavior, and broader MySQL-compatible metadata
and SQL coverage.

Highlights

• Added initial Tableau connectivity through MySQL Connector/J and Tableau's
  Other Databases (JDBC) path.
• Added Tableau compatibility coverage for connection setup, metadata discovery,
  worksheets, custom SQL, extracts, relationships, and Superstore-style queries.
• Mounted StringSearch in standard mode and improved StringLexBSI equality and
  prefix filtering behavior.
• Added ALTER TABLE ... ADD COLUMN, including populated standard-mode tables.
• Added loader flush and commit endpoints for explicit lifecycle control.
• Improved view expansion, date filters, grouped expressions, CASE, HOUR,
  relationship joins, and schema-scoped metadata probes.
• Exposed foreign-key metadata used by MySQL Workbench reverse engineering and
  Tableau relationship workflows.

Reliability and security

• Added torn-tail WAL recovery and startup truncation before subsequent writes.
• Added verified Pogreb startup handling around the local KV store.
• Bound the specialized TPC-H Q17 rewrite values instead of interpolating SQL
  literals.
• Added prepared-statement limits and strict binary date/time validation.
• Fixed MySQL CLI metadata handling and partitioned primary-key authority
  manifests.
• Restored standard-mode UPDATE and DELETE execution for residual predicates
  and row-local assignment expressions.
• Promoted the extended SQLRunner suites into the GitHub CI release gate.

Packaging and documentation

• Rebranded source-built admin commands as qstream-admin.
• Added neutral default SQL credentials in examples.
• Refreshed development, loader, relationship, provenance, and benchmark-scope
  documentation.
• The Linux/AMD64 bundle includes binaries, configuration, operational examples,
  checksums, provenance metadata, and a restorable TPC-H SF0.01 sample.

Current boundaries

• Tableau support is initial compatibility, not complete Tableau or MySQL SQL
  parity. Use the documented JDBC connection path.
• Native relationship vectors should be selected before loading. QuantaStream
  does not yet rebuild a relationship vector with ALTER TABLE ... ADD FOREIGN KEY on a populated table.
• The optimized correlated-subquery rewrite currently targets the documented
  TPC-H Q17 shape; other correlated aggregate shapes may use a slower path or be
  rejected.

Validation

• Passed go test ./... -count=1 -timeout=2m.
• Verified archive and binary checksums and embedded build identity.
• Passed the packaged end-to-end smoke covering the bundled TPC-H restore,
  interactive MySQL CLI query, JSON loader ingest, static auth and access
  controls, WAL inspection, quiescent backup, validation, restore, support
  bundle creation, and restored-row query.

Full changelog: v0.1.0...v0.1.1

QuantaStream 0.1.1-rc5

QuantaStream 0.1.1-rc5

This release candidate restores the supported standard-mode mutation paths uncovered by expanded SQLRunner validation.

Fixes

• Wired the existing projection-materialization kernel into inabox-standard mutation session handles.
• Restored correct UPDATE and DELETE behavior for residual predicates, including LIKE and NOT LIKE.
• Restored row-local UPDATE ... SET column = expression execution in standard mode.
• Added a standard-session regression test for mutation materialization wiring.
• Promoted the extended SQLRunner suites into the GitHub CI release gate.

Documentation

• Documented flat and nested loader event shapes and their intended batch and streaming use cases.

Release validation

• Passed go test ./... -count=1 -timeout=2m.
• Passed all core and extended inabox-standard SQLRunner suites, including the complete mutation suite with its original supported expectations.
• Verified archive and binary checksums and embedded version metadata.
• Passed loader, static auth, WAL, backup, restore, support-bundle, and restored-query artifact smoke checks.

This is a prerelease build intended for validation before QuantaStream 0.1.1.

QuantaStream 0.1.1-rc4

QuantaStream 0.1.1-rc4

This release candidate fixes two first-run issues found while validating RC3.

Fixes

• Fixed MySQL CLI interactive sessions disconnecting after automatic table and column completion. COM_FIELD_LIST metadata now includes the protocol-required default-value field, so the standard mysql command works without -A.
• Fixed BSI primary-key authority manifests for time-partitioned tables. Partitioned artifact roots are now discovered and recorded correctly instead of reporting a missing default bundle.

Release validation

• Restored and queried the bundled TPC-H SF0.01 backup.
• Confirmed all manifest-described authority artifacts are present.
• Exercised MySQL CLI automatic completion and verified the 60,175-row lineitem count.
• Passed loader, static auth, WAL, backup, restore, and support-bundle smoke checks.

This is a prerelease build intended for validation before QuantaStream 0.1.1.

QuantaStream 0.1.1-rc3

QuantaStream 0.1.1-rc3

Release candidate focused on hardening the 0.1.1 surface before wider testing.

Highlights

• Hardened MySQL prepared statement handling with a per-session cap and invalid binary datetime rejection.
• Hardened local WAL replay for torn-tail recovery and added KV store integrity checks.
• Bound Q17 correlated-subquery helper filter values instead of formatting literals back into SQL.
• Added schema column ID validation and catalog discovery readiness fixes.
• Documented nested streaming relationship payload support.
• Clarified relationship-vector benchmark wording and Q17-specific rewrite scope.

Notes

• This is a prerelease validation build.
• The public README remains pointed at the latest stable release until final 0.1.1.
• Full RBAC remains future work; current auth is static accounts plus access policy.
