[jira] [Created] (KAFKA-6150) Make Repartition Topics Transient

Guozhang Wang created KAFKA-6150:
------------------------------------

             Summary: Make Repartition Topics Transient
                 Key: KAFKA-6150
                 URL: https://issues.apache.org/jira/browse/KAFKA-6150
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang


Unlike changelog topics, the repartition topics could just be short-lived. Today users have different ways to configure them with short retention such as enforce a short retention period or use AppendTime for repartition topics. All these would be cumbersome and Streams should just do this for the users.

One way to do it is use the “purgeData” admin API (KIP-107) such that after the offset of the input topics are committed, if the input topics are actually repartition topics, we would purge the data immediately.
