Could you please fix the failed unit tests and add a ALTER TABLE ... REORGANIZE PARTITION SQL to here: https://github.com/pingcap/tiflow/blob/master/tests/integration_tests/partition_table/data/prepare.sql#L28 to test whether TiCDC can handle this DDL expectedly.

@mjonss: Your PR was out of date, I have automatically updated it for you.

At the same time I will also trigger all tests for you:

/run-all-tests

trigger some heavy tests which will not run always when PR updated.

If the CI test fails, you just re-trigger the test that failed and the bot will merge the PR for you after the CI passes.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the ti-community-infra/tichi repository.
