> 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.
