charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces DeferredIndexChangeService (interface + DeferredIndexChangeServiceImpl) to track pending deferred ADD INDEX operations within an upgrade session and emit the compensating SQL when subsequent schema changes interact with them: - RemoveIndex on a pending deferred ADD → cancel (DELETE) instead of DROP INDEX - RemoveTable → cancel all pending deferred indexes on that table - RemoveColumn → cancel pending deferred indexes referencing that column - RenameTable → UPDATE tableName in PENDING rows and update in-memory tracking - ChangeColumn (rename) → UPDATE columnName in PENDING column rows AbstractSchemaChangeVisitor delegates entirely to DeferredIndexChangeService, keeping SQL construction out of the visitor. The service is independently tested with 19 unit tests covering edge cases: multiple indexes on the same table, partial column matches, case-insensitivity, and single-UPDATE coverage for multi-index column renames.

Progress logged at 30s intervals. Stage 8: awaitCompletion() polls the queue for multi-instance deployments where non-executor nodes must block until index builds finish. Stage 9: DeferredIndexRecoveryService detects stale IN_PROGRESS operations (exceeded staleThresholdSeconds) and resets or completes them based on whether the index exists in the schema. Stage 10: DeferredIndexValidator force-executes any PENDING operations before a new upgrade runs, ensuring no missing indexes. Supporting changes: DeferredIndexTimestamps utility, retryBaseDelayMs config field, DAO.hasNonTerminalOperations(), SqlDialect base method for deferred index DDL. 28 tests (10 executor, 6 recovery, 4 validator, 8 unit) all passing. Coverage: Executor 87%/81%, Recovery 100%, Validator 100%, Timestamps 100%.

DeferredIndexExecutor.buildIndex() now uses a dedicated autocommit connection because PostgreSQL's CONCURRENTLY cannot run inside a transaction block. This is harmless for other platforms.

Subject: [PATCH 38/89] Ensure deferred index tables exist before parallel
 upgrade steps

Mark CreateDeferredIndexOperationTables as @ExclusiveExecution @Sequence(1)
so it acts as a barrier in GraphBasedUpgrade, guaranteeing the infrastructure
tables exist before any addIndexDeferred() step inserts into them.

Fix TestDeferredIndexService tests for awaitCompletion() throw-before-execute
behavior added in prior commit. Add integration test for fresh-database
same-batch upgrade and unit tests verifying graph dependency structure.

Subject: [PATCH 39/89] Rename DeferredIndexValidator to
 DeferredIndexReadinessCheck, wire into upgrade
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename the pre-upgrade readiness check to better reflect its purpose.
Wire it into Upgrade.findPath() so it runs automatically for both the
sequential and graph-based upgrade paths. If the DeferredIndexOperation
table does not yet exist (first upgrade), the check is a safe no-op.

Post-upgrade deferred index execution is NOT auto-wired — adopters
must explicitly call DeferredIndexService.execute() after upgrade.
The readiness check serves as a safety net: any forgotten pending
operations are force-built before the next upgrade proceeds.

This caused all integration tests using H2v2 to silently fall back to immediate AddIndex — the deferred index path was never exercised. Also fixes testDeferredAddFollowedByChangeIndex which previously asserted 0 operations after changeIndex (only correct when deferred was unsupported). With deferred support enabled, changeIndex on a pending deferred correctly cancels the old and re-tracks the new as PENDING.

charset=UTF-8 Content-Transfer-Encoding: 8bit When false (the default), addIndexDeferred() behaves identically to addIndex() — indexes are built immediately during the upgrade. The tracking table is unaffected. Checks at: - SchemaChangeSequence.Editor.addIndexDeferred() — primary gate - SchemaChangeSequence.Editor.addIndex() — gates forceDeferredIndexes - DeferredIndexReadinessCheckImpl — both methods are no-ops when disabled - DeferredIndexExecutorImpl.execute() — returns immediately when disabled Force-immediate and force-deferred overrides log at INFO level when triggered. Added integration test verifying disabled behavior. All deferred index config grouped under a section comment in UpgradeConfigAndContext.

Deferred index creation is now driven by the isDeferred() flag on the Index itself. SchemaChangeSequence.Editor.addIndex() resolves config overrides (kill switch, forceImmediate, forceDeferred) to set the effective deferred flag. AbstractSchemaChangeVisitor.visit(AddIndex) generates COMMENT ON TABLE for deferred indexes instead of CREATE INDEX. visit(RemoveIndex), visit(ChangeIndex), and visit(RenameIndex) use IF EXISTS for deferred indexes. visit(RemoveColumn) removes deferred indexes referencing the dropped column. visit(RenameTable) regenerates the deferred index comment.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the DeferredIndexOperationDAO-based executor with a comments-based approach: the executor opens a SchemaResource, finds indexes where isDeferred()=true (virtual indexes from table comments not yet physically built), and builds them using deferredIndexDeploymentStatements(). Remove DeferredIndexOperation POJO, DAO, status enum, and the CreateDeferredIndexOperationTables upgrade step. Remove forceBuildAllPending() from the readiness check — the visitor now handles deferred indexes in-place. Simplify DeferredIndexService: add getMissingDeferredIndexStatements() to expose raw SQL for applications that want custom execution. Remove getProgress() (no tracking table to query). Simplify UpgradeConfigAndContext: remove exponential backoff config (retryBaseDelayMs, retryMaxDelayMs, forceBuildTimeoutSeconds).

charset=UTF-8 Content-Transfer-Encoding: 8bit Add 8 new test scenarios covering previously untested code paths: - Same-step: add deferred then remove/change/rename in same step - Cross-step unbuilt: deferred index not yet built, later step removes/changes/renames it ("change the plan" path) - Cross-step built: deferred index physically built, later step removes/renames it Fix MetaDataProvider merge logic: physical indexes that match a DEFERRED comment declaration now get isDeferred()=true. Previously, built deferred indexes appeared as isDeferred()=false, causing the visitor to skip comment cleanup when they were later removed — leaving ghost virtual indexes.

Add indexExistsPhysically() check after failure — if the index exists in the catalog, treat as success and skip. This prevents noisy error logs on idempotent executor re-runs. Rewrite deferred-index-comments-dev.txt as a proper JIRA description matching the format of the tracking-table branch description (Confluence wiki markup with h2/h3 headings, ||tables||, {code} blocks, numbered lists, risks table, full test scenario table).

Only matching tables are loaded. PostgreSQL queries pg_description, Oracle queries ALL_TAB_COMMENTS, H2 queries INFORMATION_SCHEMA.TABLES. Add PostgreSQL invalid index detection: before building a deferred index, the executor checks pg_index.indisvalid. If an invalid index exists (from a crashed CREATE INDEX CONCURRENTLY), it is dropped before rebuild. Change indexExistsPhysically() to use raw JDBC DatabaseMetaData.getIndexInfo() instead of SchemaResource, bypassing the MetaDataProvider merge that marks built deferred indexes as isDeferred()=true.

charset=UTF-8 Content-Transfer-Encoding: 8bit The readiness check was a pass-through that returned its input unchanged. In the comments-based model, the MetaDataProvider already includes virtual deferred indexes from table comments — no schema augmentation is needed. Removes: DeferredIndexReadinessCheck interface, DeferredIndexReadinessCheckImpl, TestDeferredIndexReadinessCheckUnit, and all references in Upgrade, Upgrade.Factory, MorfModule, TestMorfModule, TestUpgrade, DeferredIndexService javadoc.
