--------------------------------------
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:

>
> 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.
