`ACT_RU_JOB`, `ACT_RU_TIMER_JOB`, `ACT_RU_SUSPENDED_JOB`, `ACT_RU_DEADLETTER_JOB`, `ACT_RU_HISTORY_JOB`, `ACT_RU_EXTERNAL_JOB` (with exception and custom value FKs to `ACT_GE_BYTEARRAY`, plus job scope and duedate indexes). + - **Removed extraneous `RETRIES_`** column from `ACT_RU_DEADLETTER_JOB` to match Flowable entity model (`DeadLetterJobEntityImpl`) and all standard relational dialects. + - `ACT_RU_TASK`, `ACT_HI_TASKINST`, `ACT_HI_TSK_LOG` (with `ACT_HI_TSK_LOG.ID_` configured as `INT64 NOT NULL GENERATED BY DEFAULT AS IDENTITY (BIT_REVERSED_POSITIVE)` per `GSQL-C1`). + - `ACT_RU_VARIABLE`, `ACT_HI_VARINST` (with FK to `ACT_GE_BYTEARRAY` and variable scope indexes). + - `ACT_RU_EVENT_SUBSCR` (with event config and scope indexes). + - Ensured all primary keys follow GoogleSQL `PRIMARY KEY (col)` syntax and columns are typed to native GoogleSQL types (`STRING(n)`, `STRING(MAX)`, `BYTES(MAX)`, `INT64`, `BOOL`, `TIMESTAMP`, `FLOAT64`). + +2. **Common Engine Drop DDL (`flowable.spanner.drop.common.sql`)**: + - Added `ALTER TABLE DROP CONSTRAINT ;` for all 12 foreign key constraints declared in `create.common.sql` (`ACT_FK_JOB_EXCEPTION`, `ACT_FK_JOB_CUSTOM_VALUES`, `ACT_FK_TIMER_JOB_EXCEPTION`, `ACT_FK_TIMER_JOB_CUSTOM_VALUES`, `ACT_FK_SUSPENDED_JOB_EXCEPTION`, `ACT_FK_SUSPENDED_JOB_CUSTOM_VALUES`, `ACT_FK_DEADLETTER_JOB_EXCEPTION`, `ACT_FK_DEADLETTER_JOB_CUSTOM_VALUES`, `ACT_FK_EXTERNAL_JOB_EXCEPTION`, `ACT_FK_EXTERNAL_JOB_CUSTOM_VALUES`, `FLW_FK_BATCH_PART_PARENT`, `ACT_FK_VAR_BYTEARRAY`). + - Added `DROP INDEX IF EXISTS ;` for all 67 secondary indexes created in `create.common.sql` prior to dropping tables. + - Dropped all 20 common tables in reverse-dependency order with `DROP TABLE IF EXISTS ...`. + +3. **Process Engine Core Schema DDL (`flowable.spanner.create.engine.sql`)**: + -

Converted nullable uniqueness constraint on `ACT_RE_PROCDEF (KEY_, VERSION_, DERIVED_VERSION_, TENANT_ID_)` to `CREATE UNIQUE NULL_FILTERED INDEX ACT_UNIQ_PROCDEF` per `GSQL-C5`. + - Converted uniqueness on `ACT_PROCDEF_INFO (PROC_DEF_ID_)` to `CREATE UNIQUE NULL_FILTERED INDEX ACT_UNIQ_INFO_PROCDEF`. + - Established secondary indexes on execution business key, root proc inst, reference ID, and runtime activity instances. + - Defined foreign key constraints linking common tables to engine tables. + - Populated engine seed properties: `('schema.version', '8.1.0.1', 1)` and `('schema.history', 'create(8.1.0.1)', 1)`. + +4. **Process Engine Core Drop DDL (`flowable.spanner.drop.engine.sql`)**: + - Stripped invalid `IF EXISTS` clause from all 31 `ALTER TABLE DROP CONSTRAINT ;` statements (Cloud Spanner GoogleSQL DDL parser does not support `IF EXISTS` on `DROP CONSTRAINT`). + - Corrected index names on `ACT_RE_MODEL` and `ACT_PROCDEF_INFO` to include missing `_IDX_`: `ACT_IDX_MODEL_SOURCE`, `ACT_IDX_MODEL_SOURCE_EXTRA`, `ACT_IDX_MODEL_DEPLOYMENT`, `ACT_IDX_PROCDEF_INFO_JSON`, and `ACT_IDX_PROCDEF_INFO_PROC`. + - Added missing unique index drops: `DROP INDEX IF EXISTS ACT_UNIQ_PROCDEF;` and `DROP INDEX IF EXISTS ACT_UNIQ_INFO_PROCDEF;`. + - Drops all 7 engine tables in reverse dependency order: `ACT_RU_ACTINST`, `ACT_RE_MODEL`, `ACT_PROCDEF_INFO`, `ACT_RU_EXECUTION`, `ACT_RE_PROCDEF`, `ACT_RE_DEPLOYMENT`, `ACT_EVT_LOG`. + +5. **Process Engine History Schema DDL (`flowable.spanner.create.history.sql`)**: + - Defined BPMN history tables: `ACT_HI_PROCINST`, `ACT_HI_ACTINST`, `ACT_HI_DETAIL`, `ACT_HI_COMMENT`, `ACT_HI_ATTACHMENT`. + - Converted nullable uniqueness on `ACT_HI_PROCINST.PROC_INST_ID_` to `CREATE UNIQUE NULL_FILTERED INDEX ACT_UNIQ_HI_PROC_INST` per `GSQL-C5`. + - Created foreign key secondary indexes on process instance, activity instance, detail, historic variable instance, historic identity link, and historic task instance. + +6. **Process Engine History Drop DDL (`flowable.spanner.drop.history.sql`)**: + - Added `DROP INDEX IF EXISTS` for all 19 history indexes (`ACT_UNIQ_HI_PROC_INST` + 18 secondary indexes) prior to table drops. + - Drops history tables with `DROP TABLE IF EXISTS ...` in reverse dependency order: `ACT_HI_ATTACHMENT`, `ACT_HI_COMMENT`, `ACT_HI_DETAIL`, `ACT_HI_ACTINST`, `ACT_HI_PROCINST`. + +## Decisions & Defaults +- **Table Partitioning / Layout**: Followed developer-confirmed policy [`SPN-D4`](file:///usr/local/google/home/vaibhavch/sam-teamfood/flowable-engine/.sam/plan.md#L46) using flat standalone tables with secondary indexes rather than interleaved composite keys, maintaining uniform `ID_ STRING(64)` primary keys across Flowable entities. +- **Identity Key Generation**: Applied native GoogleSQL `BIT_REVERSED_POSITIVE` identity generators (`GSQL-C1`) for auto-incrementing serial columns (`ACT_EVT_LOG.LOG_NR_` and `ACT_HI_TSK_LOG.ID_`) to avoid monotonically increasing sequential hotspotting without requiring separate sequences. +- **Nullable Uniqueness Constraint**: Used `CREATE UNIQUE NULL_FILTERED INDEX` (`GSQL-C5`) instead of standard unique constraints on nullable composite columns (`ACT_RE_PROCDEF`, `ACT_PROCDEF_INFO`, `ACT_HI_PROCINST`) to prevent treating multiple null keys as constraint collisions. +- **Index and Foreign Key Teardown Order**: Cloud Spanner strictly prohibits dropping a table if secondary indexes exist on it or if active foreign key constraints reference it. Teardown scripts are sequenced: Foreign Keys -> Indexes -> Tables. +- **GoogleSQL Drop Constraint Syntax**: Cloud Spanner does not support `ALTER TABLE ... DROP CONSTRAINT IF EXISTS`. All constraint drops use standard `ALTER TABLE DROP CONSTRAINT ;`. + +## Verification & Test Status +- Enhanced unit test suites following TDD: + - `SpannerCommonDdlTest` in `modules/flowable-engine-common`: + - Asserts that `DROP CONSTRAINT IF EXISTS` is never present in drop scripts. + - Extracts all foreign key constraints created in `create.common.sql` and verifies matching `ALTER TABLE ... DROP CONSTRAINT` statements in `drop.common.sql`. + - Extracts all created indexes from `create.common.sql` and verifies matching `DROP INDEX IF EXISTS` statements in `drop.common.sql`. + - Asserts absence of extraneous `RETRIES_` column in `ACT_RU_DEADLETTER_JOB`. + - Verifies all 20 common tables are created and dropped cleanly. + - `SpannerProcessEngineDdlTest` in `modules/flowable-engine`: + - Asserts that `DROP CONSTRAINT IF EXISTS` is never present in engine or history drop scripts. + - Extracts all foreign keys created in `create.engine.sql` and verifies matching drops in `drop.engine.sql`. + - Extracts all created indexes from `create.engine.sql` and `create.history.sql` and verifies matching `DROP INDEX IF EXISTS` statements in `drop.engine.sql` and `drop.history.sql`. + - Verifies all 7 engine tables and 5 history tables are created and dropped cleanly. +- TDD Red-Green cycle: + - **Red Phase**: Enhanced test assertions failed as expected on missing FK/index teardowns in `drop.common.sql`. + - **Green Phase**: Applied DDL fixes across all scripts; all tests passed cleanly. +- Full Test Suite Execution: + - `./mvnw test -pl modules/flowable-engine-common,modules/flowable-engine -am -Dtest=*Spanner* -Dsurefire.failIfNoSpecifiedTests=false`: + -

[`modules/flowable-engine-common/src/main/java/org/flowable/common/engine/impl/db/AbstractSqlScriptBasedDbSchemaManager.java`](file:///usr/local/google/home/vaibhavch/sam-teamfood/flowable-engine/modules/flowable-engine-common/src/main/java/org/flowable/common/engine/impl/db/AbstractSqlScriptBasedDbSchemaManager.java): + - Aligned DDL execution with Cloud Spanner's transaction model ([`JDBC-C5`](file:///usr/local/google/home/vaibhavch/.gemini/config/plugins/sam/skills/sam-knowledge/references/spanner/access/spanner-jdbc/conversion.md#L78)): Cloud Spanner rejects DDL statements executed inside a multi-statement transaction (`autoCommit = false`) with `FAILED_PRECONDITION: DDL-statements are not allowed inside a read/write transaction`. + - In `executeSchemaResource()`, when `databaseType` is `spanner`, the initial `autoCommit` state is saved and temporarily switched to `true` (`connection.setAutoCommit(true)`) so DDL statements execute in autocommit mode. The previous `autoCommit` setting is restored in a `finally` block before returning the connection to the MyBatis session. + - Added `isSpannerConcurrentSchemaChange()` collision detection and retry loop with exponential backoff (`200ms * retryCount`, up to 5 attempts) to prevent sequential DDL collisions when rapid schema operations are in progress (`JDBC-V5`). + - Added `isSpannerNotFoundException()` handling during drop operations (`"drop".equals(operation)` and `"spanner".equals(databaseType)`): ignores `NOT_FOUND` errors (e.g. "is not a constraint in", "Table not found", code NOT_FOUND) instead of setting `exception = e`, since GoogleSQL does not support `ALTER TABLE ...

For Spanner, DDL statements must execute in autocommit mode. Toggling `autoCommit` during schema operations preserves MyBatis transaction semantics for application DML while allowing DDL creation and teardown scripts to run seamlessly. +- **Teardown Ordering in Tests**: `processEngine.close()` cleans up active engine state before tables are dropped, ensuring clean, error-free shutdown. +- **Graceful Fallback**: Test suite gracefully skips emulator execution if the Spanner JDBC driver is not on the classpath or if the emulator port 9010 is not running, ensuring `mvn test` without `-Pspanner` continues to build cleanly. + +## Reviewer Rework & Teardown Idempotency Actions +1. **CI Workflow URL and Surefire Args**: + - Appended `;lenient=true;` to `-Djdbc.url` in `.github/workflows/spanner.yml`. + - Added `-Dsurefire.failIfNoSpecifiedTests=false` to Maven test command in CI so reactor builds with `-am` do not fail on upstream modules lacking Spanner tests. +2. **DataSource Resource Cleanup**: + - Implemented `AutoCloseable` on `ClosingDataSource` and invoked `close()` inside a `try ... finally` block in `SpannerEngineIntegrationTest.testFlowableSpannerConfigurationParsing()`. +3. **Teardown Idempotency on Spanner**: + - In `AbstractSqlScriptBasedDbSchemaManager`, ignored `NOT_FOUND` exceptions during drop statements on Spanner (`isSpannerNotFoundException`) so missing constraints do not abort or flag the drop as failed. + - In `ProcessDbSchemaManager`, separated engine and history drops into separate `try-catch` blocks so an engine drop error never bypasses history drop. + - In `flowable.spanner.drop.common.sql`, added defensive index drops for history indices on common tables before dropping common tables. +4. **Consecutive Verification Runs**: + -
