Work Description: echauchot commented on pull request #11055: [BEAM-9436]
improve GBK
URL: https://github.com/apache/beam/pull/11055
Could not avoid materialization because ReduceFnRunner needs an
Iterable<WindowedValue<InputT>> but managed to avoid a flatmap step and memory
consumption with KV creation.
