Matthias J. Sax updated KAFKA-4730:
-----------------------------------
Description:
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.
