Luke Cwik updated BEAM-7912:
----------------------------
Status: Open (was: Triage Needed)
> Optimize GroupIntoBatches for batch Dataflow pipelines
> ------------------------------------------------------
>
> Key: BEAM-7912
> URL: https://issues.apache.org/jira/browse/BEAM-7912
> Project: Beam
> Issue Type: Improvement
> Components: runner-dataflow
> Reporter: Luke Cwik
> Assignee: Luke Cwik
> Priority: Minor
>
> 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.
