### What doesn't meet your expectations?

unstable test

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start with FlinkCatalogITCase.testCreateNoPkTable at line 172 and reproduce the failure from the linked GitHub Actions run. Investigate why creating the append_only_table intermittently reaches the 600-second timeout, then rerun the integration test to verify it completes reliably.
