rajinisivaram opened a new pull request #9406: URL: https://github.com/apache/kafka/pull/9406
We currently stop polling in `Sender` in a transactional producer if there is only one broker in the bootstrap server list and `max.in.flight.requests.per.connection=1` and Metadata response is pending when InitProducerId request is ready to be sent. In this scenario, we attempt to send FindCoordinator to `leastLoadedNode`, but since that is blocked due to `max.in.flight=1` as a result of the pending metadata response, we never unblock unless we poll. This PR ensures we poll in this case. ### 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.
