dajac opened a new pull request #8801: URL: https://github.com/apache/kafka/pull/8801
We have noticed that the `LiveLeaders` field in the LeaderAndIsrRequest is not used anywhere but still populated by the controller. It seems that that field was introduced in AK `0.8.0` and was supposed to be removed in AK `0.8.1`: https://github.com/apache/kafka/blob/0.8.0/core/src/main/scala/kafka/cluster/Partition.scala#L194. It has not been used since then. This PR proposes to simply stop populating the field for any version > 0. It avoids to compute the live leaders set and also reduces the size of the request on the wire. ### 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.
