dimitarndimitrov opened a new pull request, #18635: URL: https://github.com/apache/kafka/pull/18635
Although `MetadataCache`'s `getPartitionReplicaEndpoints` takes a single topic-partition, the `KRaftMetadataCache` implementation iterates over all partitions of the matching topic. This is not necessary and can cause significant performance degradation when the topic has a relatively high number of partitions. Note that this is not a recent regression - it has been a part of `KRaftMetadataCache` since its creation. ### 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.
