> Byte-based GroupByKey in Flink Streaming
> ----------------------------------------
>
> Key: BEAM-11443
> URL: https://issues.apache.org/jira/browse/BEAM-11443
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Reporter: David Morávek
> Assignee: David Morávek
> Priority: P3
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> 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.
