> 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.
