---------------------------------
Assignee: Heejong Lee
> PCollectionList support in cross-language transforms
> ----------------------------------------------------
>
> Key: BEAM-8804
> URL: https://issues.apache.org/jira/browse/BEAM-8804
> Project: Beam
> Issue Type: Improvement
> Components: beam-model
> Reporter: Heejong Lee
> Assignee: Heejong Lee
> Priority: Major
>
> Currently, Beam model doesn't have any information on the order of output
> PCollections from PTransforms. So, PCollectionList needs to be converted to
> PCollectionTuple when it goes across the cross-language boundary (or even in
> the same language, when it is converted between in-memory object and proto).
