Thanos Athanasopoulos commented on KAFKA-16798:
-----------------------------------------------
Hi [~gharris1727], thanks for your input !
I forgot to mention that, behaviorally, I have checked the lag in the
destination cluster and indeed the offsets are being synced after 60 seconds
and exactly at the time I receive the following logs in MM.
[2024-05-20 09:33:44,850] INFO [MirrorSourceConnector|task-0|offsets]
WorkerSourceTask\{id=MirrorSourceConnector-0} Committing offsets for 21
acknowledged messages (org.apache.kafka.connect.runtime.WorkerSourceTask:233)
[2024-05-20 09:33:44,854] INFO [MirrorSourceConnector|task-1|offsets]
WorkerSourceTask\{id=MirrorSourceConnector-1} Committing offsets for 12
acknowledged messages (org.apache.kafka.connect.runtime.WorkerSourceTask:233)
I will check your recommendations.
