David Arthur created KAFKA-15799: ------------------------------------ Summary: ZK brokers incorrectly handle KRaft metadata snapshots Key: KAFKA-15799 URL: https://issues.apache.org/jira/browse/KAFKA-15799 Project: Kafka Issue Type: Bug Reporter: David Arthur Assignee: David Arthur Fix For: 3.6.1
While working on the fix for KAFKA-15605, I noticed that ZK brokers are unconditionally merging data from UpdateMetadataRequest with their existing MetadataCache. This is not the correct behavior when handling a metadata snapshot from the KRaft controller. For example, if a topic was deleted in KRaft and not transmitted as part of a delta update (e.g., during a failover) then the ZK brokers will never remove the topic from their cache (until they restart and rebuild their cache). -- This message was sent by Atlassian Jira (v8.20.10#820010)
