>                 Key: BEAM-10012
>                 URL: https://issues.apache.org/jira/browse/BEAM-10012
>             Project: Beam
>          Issue Type: New Feature
>          Components: sdk-py-core
>            Reporter: Chamikara Madhusanka Jayalath
>            Priority: Major
>
> Currently, portable runners are expected to do following when constructing a runner specific job.
> SDK specific job graph -> Beam runner API proto -> Runner specific job request
> Portable Spark and Flink follow this model.
> Dataflow does following.
> SDK specific job graph -> Runner specific job request
> Beam runner API proto -> Upload to GCS -> Download at workers
>  
> We should update Dataflow to follow the prior path which is expected to be followed by all portable runners.
> This will simplify the cross-language transforms job construction logic for Dataflow.
> We can probably start this by just implementing this for Python SDK for portions of pipeline received by expanding external transforms.
