> Key: BEAM-2902
> URL: https://issues.apache.org/jira/browse/BEAM-2902
> Project: Beam
> Issue Type: Sub-task
> Components: runner-dataflow
> Reporter: Luke Cwik
> Priority: Minor
> Labels: portability, sickbay
> Fix For: 2.11.0
>
>
> Add support for user state in a ParDo.Multi by:
> * adding expansion/conversion logic within Dataflow service to add any needed
> GBKs to allow expansion.
> *OR*
> * Add support for expansion inside the Beam SDK once the PTransformMatcher
> exposes a way to know when the replacement is not required by checking that
> the preceding ParDos to a GBK are key preserving.
