Hello!
When I saw KAFKA-4730/KIP-428 ("Streams does not have an in-memory windowed
store") were included in 2.3.0, I thought maybe it would be possible to
configure an in-memory stream-stream join using KStream#join. But I am not
seeing this in the API. My use case is joining streams of short-lived
events that service a request/response flow. The join doesn't have to be
durable at all.Dmitry
