> 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.
