[jira] [Created] (SAMZA-2352) Use min.compaction.lag.ms to avoid compacting the Kafka changelog topic

Xinyu Liu created SAMZA-2352:
--------------------------------

             Summary: Use min.compaction.lag.ms to avoid compacting the Kafka changelog topic
                 Key: SAMZA-2352
                 URL: https://issues.apache.org/jira/browse/SAMZA-2352
             Project: Samza
          Issue Type: Sub-task
            Reporter: Xinyu Liu
            Assignee: Xinyu Liu


To enable transactional state, we will need to avoid the head of the changelog (the ones after last checkpoint) not being log-compacted so we can trim the rest of the updates. We use min.compaction.log.ms to control the compaction time.
