> Flink runner per operator SDK harness option

> Key: BEAM-5520
> URL: https://issues.apache.org/jira/browse/BEAM-5520
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Reporter: Thomas Weise
> Assignee: Thomas Weise
> Priority: Major
> Labels: portability, portability-flink
> Time Spent: 2h
> Remaining Estimate: 0h
>
> For streaming pipelines, the runner currently uses a single SDK harness
> process for all subtasks of a job that get deployed on the same task manager.
> In common deployments with 16 or more tasks slots, many executable stage
> operators all use the same SDK harness process. To scale, we need an option
> to run separate harness processes per subtask.
