>                 Key: KAFKA-6910
>                 URL: https://issues.apache.org/jira/browse/KAFKA-6910
>             Project: Kafka
>          Issue Type: New Feature
>          Components: streams
>    Affects Versions: 1.1.0, 1.1.1
>            Reporter: Antony Stubbs
>            Priority: Major
>
> 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.
