Colin McCabe created KAFKA-16624: ------------------------------------ Summary: Don't generate useless PartitionChangeRecord on older MV Key: KAFKA-16624 URL: https://issues.apache.org/jira/browse/KAFKA-16624 Project: Kafka Issue Type: Bug Reporter: Colin McCabe Assignee: Colin McCabe
Fix a case where we could generate useless PartitionChangeRecords on metadata versions older than 3.6-IV0. This could happen in the case where we had an ISR with only one broker in it, and we were trying to go down to a fully empty ISR. In this case, PartitionChangeBuilder would block the record to going down to a fully empty ISR (since that is not valid in these pre-KIP-966 metadata versions), but it would still emit the record, even though it had no effect. -- This message was sent by Atlassian Jira (v8.20.10#820010)
