> MVP for SDK worker changes to support process_batch

> Key: BEAM-14294
> URL: https://issues.apache.org/jira/browse/BEAM-14294
> Project: Beam
> Issue Type: Sub-task
> Components: sdk-py-core
> Reporter: Brian Hulette
> Assignee: Brian Hulette
> Priority: P2
> Time Spent: 1h 40m
> Remaining Estimate: 0h

> The initial MVP may only work in some restricted circumstances (e.g.
> @yields_element on process_batch, or batch-to-batch without a 1:1
> input:output mapping might not be supported). These cases should fail early.
