Labels: auto-unassigned (was: stale-assigned)
> remove aggregateResultType from streaming.api.datastream.aggregate
> ------------------------------------------------------------------

> Key: FLINK-5914
> URL: https://issues.apache.org/jira/browse/FLINK-5914
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Shaoxuan Wang
> Assignee: Shaoxuan Wang
> Priority: Major
> Labels: auto-unassigned
>
> aggregateResultType does not seem necessary for
> streaming.api.datastream.aggregate. We will anyway not serialize the
> aggregateResult between aggregate and window function. Aggregate function
> itself provides a function to getResult(), window function here should just
> emit the same results as aggregate output. So aggregateResultType should be
> same as resultType. I think we can safely remove aggregateResultType, thereby
> user will not have to provide two same types for the
> streaming.api.datastream.aggregate.
> [~StephanEwen], what do you think?
