…iming

Wait for the job to be fully running and use collision-free slot names so the Postgres newly-added-table failover test stops racing the runtime.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Skip redundant cancellation after stop-with-savepoint so PostgresPipelineITCase does not fail on already-terminated jobs.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Delay failover-sensitive assertions until snapshot data is visible so the MySQL newly-added-table test stops racing split handoff and upsert convergence.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Bound and simplify the varbinary sink waits in MySqlConnectorITCase so stalled conversions fail fast instead of hanging the suite.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Allow one balanced duplicate update pair in the MongoDB newly-added-table restore path so the test stays focused on required changelog coverage.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Replace fixed sleeps with sink polling in Oracle NewlyAddedTableITCase so upsert assertions wait for the actual emitted rows.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Use isolated databases, hourly-offset timezones, and bounded sink waits so SqlServerTimezoneITCase stops depending on unsupported timezone offsets and unbounded polling.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Tighten Iceberg commit coordination and its E2E assertions so concurrent schema and checkpoint activity no longer flakes MySqlToIcebergE2eITCase.

… assertions

Add shared log-fragment waits and explicit stream-split handoff checks so TransformE2eITCase and UdfE2eITCase only assert incremental output after snapshot completion.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Reduce the extreme route fan-out and wait for batch jobs to finish before validating output so RouteE2eITCase stops timing out on starved runners.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for the SQL Server pipeline job and stream split assignment to be fully ready before asserting incremental changes.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…eITCase

Allow the Oracle E2E assertions to match both fixture ids and legacy NUMBER renderings so customer snapshot checks stay stable across environments.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Use a direct fallback assertion for the optional retry duplicate pair so the MongoDB test helper compiles across the CI matrix.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for the Mongo source snapshot to reach the sink before replaying mutations, restore Oracle pipeline acceptance of legacy NUMBER id renderings, and narrow the keyed upsert wait in Oracle newly-added-table assertions.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Add a short post-snapshot pause before issuing incremental MySQL changes so the snapshot-to-binlog handoff completes and the first updates are not lost in CI.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for the varbinary PK snapshot rows to drain before issuing binlog changes so the handoff to incremental reading doesn't leave the test stuck waiting for missing records.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Run the wildcard multi-rule transform case at local single parallelism to avoid the Flink 2.2 batch scheduling flake already seen in neighboring transform cases.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Avoid ambiguous pipeline event matches and make the multi-table transform handoff deterministic in the flaky 2.x E2E path. Also assert the varbinary PK MySQL test through the values sink so snapshot and binlog results come from one stable sink.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Accept the legacy Oracle NUMBER rendering again when matching customer insert events so the pipeline E2E suites stay stable across 1.20 and 2.2 environments.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Bound the MySQL server-id conflict assertion to a failed job so Flink 2.x does not hang until CI timeout, and pace the Hudi schema-evolution loop so the 1.20 MOR lane is not hit by a burst of DDLs.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Assert the submitted job result future directly so the conflict test stays stable when Flink 2.x shuts the MiniCluster down quickly or reaches failure later than the status-poll timeout.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for the MySqlConnectorITCase job-result future to complete instead of asserting on a fixed timed get, which was timing out after the async conflict had already surfaced. Retry OceanBase JDBC container startup so transient \"Server is initializing\" readiness races do not fail CI.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Avoid Docker Hub pull flakes for testcontainers/ryuk on ephemeral GitHub Actions runners by disabling Ryuk for pipeline and source E2E jobs, where runner teardown already cleans up containers.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Trigger a checkpoint after the schema evolution batch so Hudi MOR validation reads a flushed sink state instead of a partial intermediate snapshot.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Delay Oracle snapshot-phase failover until the job is RUNNING so JM leadership revocation does not race cluster HA service initialization.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Retry transient JobNotFound, checkpoint, and JDBC readiness races so the Oracle newly-added-table tests, TiDB connector tests, and Iceberg whole-database E2E test stop failing on startup and recovery timing.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Install Maven 3.8.6 directly from the Apache archive so pipeline jobs do not fail in setup on transient 403 responses from the action download path.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Precreate Oracle's log mining flush table as the connector user and relax the SQL Server all-types assertion so source ITs stop failing on connector-owned state and alternate timestamp rendering.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Avoid the flaky MySQL varbinary values-sink handoff by collecting source rows directly with bounded waits, and precreate Oracle's log mining flush table in the same DBA session the test source uses.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Prime redo before the empty-table transition test and use a neutral SCN primer table so Oracle log mining starts from committed SCNs without tripping the flush-table path.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Treat concurrent LOG_MINING_FLUSH creation as benign and serialize local initialization so parallel Oracle readers do not fail on ORA-00955 during failover backfill.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for snapshot rows before issuing varbinary PK binlog writes and collect results asynchronously so the test no longer stalls waiting on sink materialization.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Validate the schema-evolution sink result before checkpointing and retry the checkpoint so transient job handoff does not fail the test.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Restore the LogMiner connection state before mining starts and seed the empty-table test redo earlier so resume positions stay inside available logs.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Wait for schema events by substring so wrapped taskmanager log lines still satisfy the readiness check in parallel UDF runs.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Fetch the snapshot and binlog rows in two phases so a transient iterator gap at the handoff cannot end collection before the binlog records arrive.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Retry transient checkpoint trigger races and force checkpoints before the Hudi validations that were reading stale whole-database state under CI timing.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Allow the newly added table test to accept the duplicate update pair that can be replayed after restart, matching the later assertion path and avoiding a flaky CI-only failure.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Use substring log matching for UDF value events so Flink 2 parallel batch runs do not fail when taskmanager output wraps the event text.
