> 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.
