### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Description Our current CI pipeline is spending too much time on Flink multi-version tests. In the linked run below, the longest CI job took more than 50 minutes, which is already very close to the current 60-minute timeout configured in CI: https://github.com/apache/fluss/actions/runs/25545481655/job/74980566947?pr=3229 The main bottleneck is the Flink multi-version test stage. At the moment, we run a broad set of Flink read/write tests across multiple Flink versions. This gives us coverage, but it also introduces a large amount of duplicated execution time. In practice, we do not need to run the full read/write test set on every supported Flink version. For compatibility validation, it should be enough to: - keep the full test suite on one primary Flink version; - keep only a small set of representative end-to-end read/write smoke tests on the remaining supported Flink versions; - retain dedicated tests only where a version-specific behavior actually needs coverage. This would still protect the core compatibility path while significantly reducing duplicated test time in CI. It should also reduce the risk of hitting the 60-minute timeout, especially as more tests are added later. A possible follow-up for this task is: - review the current Flink multi-version test matrix; - identify the minimal cross-version smoke coverage we really need; - move the rest of the read/write test coverage to a single representative version; - keep version-specific tests only when they validate behavior that is genuinely different across Flink versions. ### Willingness to contribute - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
