>
> Currently, `KafkaStreams.cleanup` cleans up all the task-level directories
> and the global directory. However it doesn't clean up the enclosing state
> store directory, though streams does create this directory when it
> initializes the state for the streams app. Feels like it should remove this
> directory when it cleans up.
> We notice this in ksql quite often, since every new query is a new streams
> app. Over time, we see lots of state store directories left around for old
> queries.
