> For KTable aggregations, it has a pattern of {{table.groupBy(...).aggregate(...)}}, and the data is repartitioned in an inner topic based on the selected key in {{groupBy(...)}}.
> For KStream aggregations, though, it has a pattern of {{stream.selectKey(...).through(...).aggregateByKey(...)}}. In other words, users need to manually use a topic to repartition data, and the syntax is a bit different with KTable as well.
> h2. Goal
> To have similar APIs for aggregations of KStream and KTable
