[jira] [Created] (KAFKA-21281) MM2 sync can fail due to controller record limit being hit

Gaurav Narula created KAFKA-21281:
-------------------------------------

             Summary: MM2 sync can fail due to controller record limit being hit
                 Key: KAFKA-21281
                 URL: https://issues.apache.org/jira/browse/KAFKA-21281
             Project: Kafka
          Issue Type: Bug
          Components: mirrormaker
    Affects Versions: 4.4.0
            Reporter: Gaurav Narula
            Assignee: Gaurav Narula
         Attachments: DedicatedMirrorIntegrationTest.patch

Sync operations in MM2 can fail when the operations are > {{MAX_RECORDS_PER_USER_OP}} which is 10k.

An example of this would be syncing > 10k ACLs from the source cluster or attempting to sync ~200 topics with 50 partitions each in one go.

Refer to the integration test for a reproduction.
