[jira] [Created] (KAFKA-9539) Add leader epoch in StopReplicaRequest

David Jacot created KAFKA-9539:
----------------------------------

             Summary: Add leader epoch in StopReplicaRequest
                 Key: KAFKA-9539
                 URL: https://issues.apache.org/jira/browse/KAFKA-9539
             Project: Kafka
          Issue Type: Improvement
            Reporter: David Jacot
            Assignee: David Jacot


Unlike the LeaderAndIsrRequest, the StopReplicaRequest does not include the leader epoch which makes it vulnerable to reordering. This KIP proposes to add the leader epoch for each partition in the StopReplicaRequest and the broker will verify the epoch before proceeding with the StopReplicaRequest.
