----------------------------------
Summary: 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
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.
