------------------------------------

             Summary: Avoid creating dummy checkpoint files with no state stores
                 Key: KAFKA-6499
                 URL: https://issues.apache.org/jira/browse/KAFKA-6499
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang


Today, for a streams task that contains no state stores, its processor state 
manager would still write a dummy checkpoint file that contains some characters 
(version, size). This introduces unnecessary disk IOs and should be avoidable.
