------------------------------------
Summary: 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: Streaming
Reporter: Shaoxuan Wang
Assignee: Shaoxuan Wang
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?
