dengziming opened a new pull request, #12238: URL: https://github.com/apache/kafka/pull/12238
*More detailed description of your change* Will will generate NoOpRecord periodically to increase metadata LEO, however, when a broker startup, we will wait until its metadata LEO catches up with the controller LEO, we generate NoOpRecord every 500ms and send heartbeat request every 2000ms. It's almost impossible for a broker to catch up with the controller LEO if the broker sends a query request every 2000ms but the controller LEO increases every 500ms, so the tests in `KRaftClusterTest` will fail.  *Summary of testing strategy (including rationale)* After this change, the tests in `KRaftClusterTest` all succeed. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
