damccorm opened a new issue, #20779: URL: https://github.com/apache/beam/issues/20779
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. Imported from Jira [BEAM-11443](https://issues.apache.org/jira/browse/BEAM-11443). Original Jira may contain additional context. Reported by: dmvk. -- This is an automated message from the Apache Git Service.
