Summary: KRaft Controller doesn't reconcile with Zookeeper metadata upon becoming new controller while in dual write mode. Key: KAFKA-15010 URL: https://issues.apache.org/jira/browse/KAFKA-15010 Project: Kafka Issue Type: Bug Components: kraft Reporter: Akhilesh Chaganti When a KRaft controller fails over, the existing migration driver (in dual write mode) can fail in between Zookeeper writes and may leave Zookeeper with incomplete and inconsistent data. So when a new controller becomes active (and by extension new migration driver becomes active), this first thing we should do is load the in-memory snapshot and use it to write metadata to Zookeeper to have a steady state. We currently do not do this and it may leave Zookeeper in inconsistent state. -- This message was sent by Atlassian Jira (v8.20.10#820010)
