>             Project: Flink
>          Issue Type: Bug
>          Components: Table API & SQL
>    Affects Versions: 1.3.1, 1.4.0

> Currently we added `Cleanup State` feature. But It not work well if we enabled the stateCleaning
on Unbounded ProcTime NonPartitioned Over window, Because in `ProcessFunctionWithCleanupState`
we has using the keyed state.
> So, In this JIRA. I'll change the  `Unbounded ProcTime NonPartitioned Over` to `partitioned
Over` by using NullByteKeySelector. OR created a `NonKeyedProcessFunctionWithCleanupState`.
But I think the first way is simpler. What do you think? [~fhueske]
