      Description

      SAMZA-1427 introduced a performance regression with KafkaCheckpointManager.

      We invoke the checkpoint manager once for each task and the old code would only read the delta for each subsequent call. The SAMZA-1427 code would reread the entire checkpoint topic for each call.

      This effect is even worse when log compaction is not running on the broker.
