Fabian Hueske commented on FLINK-7471:
--------------------------------------
Are you proposing to compute all aggregates for each record completely from
scratch?
How would we separate retracting and non-retracting aggregation functions from
each other?
Does this require a major refactoring of the code-generation and aggregation
infrastructure that we implemented some months ago?
> Improve bounded OVER support non-retract method AGG
