> Currently Flink Streaming GBK is implemented using `SystemReduceFn#buffering`, that works on de-serialized values (we need to de-serialize value after shuffle and then serialize again when appending to bag state).
> We can remove this unnecessary serde cycle by using binary representation instead of de-serialized payload.
