Sean Owen commented on SPARK-12260:
-----------------------------------

I'm asking what you can't do with updateStateByKey that you need to do?
This sounds pretty app-specific, and something you can maintain in your own app or repo to
start.

> Users often stop and restart their streaming jobs for tasks such as maintenance, software
upgrades or even application logic updates. When a job re-starts it should pick up where it
left off i.e. any state information that existed when the job stopped should be used as the
initial state when the job restarts.
