Jark Wu commented on FLINK-4692:
--------------------------------
Yes. I agree to move the sliding window to a separate issue. And we can discuss
the implementation more detail in that issue.
Option 2 is a nicer way but only support combinable aggregation. Maybe we can
implement approach-1 in the first version, and do improvement in the later
issues.
