Antony Stubbs updated KAFKA-6910:
---------------------------------
    Description: 
For large projects, it's a huge pain and not really practically at all to use a 
custom state store everywhere just to use in memory or avoid rocksdb, for 
example for running a test suite on windows.

It would be great to be able to set a global config for KS so that it uses a 
different state store implementation everywhere.

Blocked by KAFKA-4730 - Streams does not have an in-memory windowed store. Also 
blocked by not having an in-memory session store implementation. A version 
simple in memory window and session store that's not suitable for production 
would still be very useful for running test suites.
