Au-Miner opened a new pull request, #28382: URL: https://github.com/apache/flink/pull/28382
## What is the purpose of the change Fix the flaky `ChangelogNormalizeRestoreTest.testRestore` failure for the `changelog-normalize-source-mini-batch` variant. The test intermittently fails because `INSERT "six"` and `DELETE "six"` can end up in the same mini-batch, causing `addInput` to overwrite the INSERT with the DELETE, resulting in both records being silently dropped. ## Brief change log - *[ChangelogNormalizeTestPrograms.java]* Added one no-op `DELETE` padding record (`"seven"`) to `AFTER_DATA` to ensure `INSERT "six"` and `DELETE "six"` are always separated into different mini-batches by `CountBundleTrigger(size=2)`, regardless of processing-time watermark timing. ## Verifying this change This change is a test-only fix. The existing `ChangelogNormalizeRestoreTest.testRestore` test validates correctness. The padding DELETE records target non-existent keys, so they produce no output and do not affect `AFTER_OUTPUT` expectations. ## Does this pull request potentially affect one of the following parts - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Currentity, Coordination, Zookeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable -- This is an automated message from the Apache Git Service.
