Henry Cai commented on KAFKA-6150:
----------------------------------
We got about 120,000 lines of loggings from those two INFO loggings in one hour
on one broker, about 33 lines per second on the server log file.
> 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

> Priority: Major
> Labels: operability
> Fix For: 1.1.0

>
> 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.
