jolshan opened a new pull request #11170: URL: https://github.com/apache/kafka/pull/11170
Before we used the metadata cache to determine whether or not to use topic IDs. Unfortunately, metadata cache updates with ZK controllers are in a separate request and may be too slow for the fetcher thread. This results in switching between topic names and topic IDs for topics that could just use IDs. This change adds topic IDs to FetcherState created in LeaderAndIsr requests. It also supports updating this state for follower threads as soon as a LeaderAndIsr request provides a topic ID. I've opted to only update replica fetcher threads. Alter Log Dir threads will use either topic name or topic ID depending on what was present when they were created. ### 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.
