Hi everyone, I’m looking for a review on KAFKA-20989, which fixes state cleanup when migrating controller servers during ZK-to-KRaft migration.
- JIRA: https://issues.apache.org/jira/browse/KAFKA-20989 - PR: https://github.com/apache/kafka/pull/23284 I also have a couple of questions: 1. Since this affects multiple pre-4.0 versions and trunk no longer contains ZK migration code, what is the preferred process for porting this fix across active 3.x branches (e.g., 3.9, 3.8)? 2. Are the current CI test failures expected flakes? They don't appear relevant to controller/migration changes and pass cleanly locally. If anyone could take a look, I'd greatly appreciate your feedback! Thanks, Youssef
