------------------------------------
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.
