Kenneth Knowles updated BEAM-6350:
----------------------------------
Labels: stale-assigned triaged (was: triaged)
> Reuse same PCollectionView when created in translators
> -------------------------------------------------------
>
> Key: BEAM-6350
> URL: https://issues.apache.org/jira/browse/BEAM-6350
> Project: Beam
> Issue Type: Improvement
> Components: dsl-euphoria
> Affects Versions: 2.11.0
> Reporter: Marek Simunek
> Assignee: David Morávek
> Priority: P2
> Labels: stale-assigned, triaged
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> If for LeftJoin is used BroadcastHashJoinTranslator then from right side is
> created PCollectionView (as sideInput).
> If we use right side in multiple joins then PCollectionView is created
> multiple times which is not optimal behavior.
> Eg.
> {code:java}
> LeftJoin.of(left, right)..
> LeftJoin.of(anotherLeftPcollection, right)..
> {code}
> For example it will happen when we want to solve skew Join.
