Kenneth Knowles commented on BEAM-2364:
---------------------------------------
I notice the added label. We should ensure that this is not backwards
incompatible for users, of course.
> PCollectionView should not be a PValue, it should expand to its underlying
> PCollection

> Project: Beam
> Issue Type: Bug
> Components: sdk-java-core
> Reporter: Kenneth Knowles
> Assignee: Thomas Groh
> Labels: backward-incompatible
>
> This bug has been present for a very long time.
> It is a change to {{@Internal}} details but is going to be
> backwards-incompatible in a couple ways there, because backwards compatible
> behavior is incorrect. But we need to be very careful with the surrounding
> logic.
> The particular motivating need is that as long as a PCollectionView expands
> to only itself, the outputs for surgery and serialization are not correct.
> There may be a solution involving hardcoded logic, TBD.
