[jira] [Created] (KAFKA-7201) Optimize repartition operations

Bill Bejeck created KAFKA-7201:
----------------------------------

             Summary: Optimize repartition operations
                 Key: KAFKA-7201
                 URL: https://issues.apache.org/jira/browse/KAFKA-7201
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Bill Bejeck
            Assignee: Bill Bejeck
             Fix For: 2.1.0


When the topology has a key changing operation, any downstream processors using the key will automatically create a repartition topic.  In most cases these multiple repartition topics can be collapsed into one repartition operation occurring immediately after the key changing operation, thus reducing streams overall footprint.
