Guozhang Wang commented on KAFKA-3185:
--------------------------------------

I think [~mjsax] has already started working on this, but did not yet assign this ticket to
himself.

There is indeed a list of newbie tickets for Kafka Streams:

https://issues.apache.org/jira/issues/?jql=project%20%3D%20KAFKA%20AND%20resolution%20%3D%20Unresolved%20AND%20component%20%3D%20streams%20AND%20labels%20in%20(newbie%2C%20%22newbie%2B%2B%22)%20ORDER%20BY%20priority%20DESC

Feel free to grab any that is not assigned yet.

> Currently the internal data is managed completely by Kafka Streams framework and users
cannot clean them up actively. This results in a bad out-of-the-box user experience especially
for running demo programs since it results internal data (changelog topics, RocksDB files,
etc) that need to be cleaned manually. It will be better to add a
> {code}
> KafkaStreams.cleanup()
> {code}
> function call to clean up these internal data programmatically.
