-------------------------------------------------------------
[~nthean] we'd love your help with this. It might be worth re-cycling the
existing in-memory store, which probably means going with separate key-value
stores for each time segment. A bit like how the persistent window store
recycles the RocksDb basic store.
This might require a KIP where we discuss the design first
(https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals).
We can guide you on that if you are interested. How does this sound?
I've tentatively assigned this JIRA to you :)

> Streams does not have an in-memory windowed store

> Key: KAFKA-4730
> URL: https://issues.apache.org/jira/browse/KAFKA-4730
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Affects Versions: 0.10.2.0
> Reporter: Eno Thereska
> Assignee: Nikki Thean
> Fix For: 0.11.0.0
>
>
> Streams has windowed persistent stores (e.g., see PersistentKeyValueFactory
> interface with "windowed" method), however it does not allow for windowed
> in-memory stores (e.g., see InMemoryKeyValueFactory interface).
> In addition to the interface not allowing it, streams does not actually have
> an implementation of an in-memory windowed store.
> The implications are that operations that require windowing cannot use
> in-memory stores.
