Review Comment:
The result returned by the AggregatingState#get is the output processed by
the user-defined AggregateFunction. At this stage, the returned data cannot be
serialized using the valueSerializer to calculate its size, so I didn’t include
the size of the AggregatingState's value in the statistics. WDYT?
