Ismaël Mejía updated BEAM-7448:
-------------------------------
Status: Open (was: Triage Needed)
> Clean spark windowing
> ---------------------
>
> Key: BEAM-7448
> URL: https://issues.apache.org/jira/browse/BEAM-7448
> Project: Beam
> Issue Type: Improvement
> Components: runner-spark
> Reporter: Etienne Chauchot
> Assignee: Etienne Chauchot
> Priority: Major
>
> In some places the Spark runner uses both external windowing and internal
> windowing in collections such as
> {code:java}
> WindowedValue<KV<K, Iterable<WindowedValue<V>>>>
> {code}
> leading to unneeded mappers and dereference
> The external windowing information is duplicated so unneeded
