The intention of using poll(0) is to not block on rebalance but still return some data; however, if there's no fetchable partitions then there's no point of polling with 0ms. What's worse, with poll(0) we may fall into a busy loop since we may advance the system test with too small pace. ### 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.
