damccorm opened a new issue, #19749: URL: https://github.com/apache/beam/issues/19749
The GroupIntoBatches transform can be significantly optimized on Dataflow since it always ensures that a key K appears in only one bundle after a GroupByKey. This removes the usage of state and timers in the generic GroupIntoBatches transform. Imported from Jira [BEAM-7912](https://issues.apache.org/jira/browse/BEAM-7912).
