[jira] [Created] (FLINK-31318) Do not scale down operators while processing backlog

Gyula Fora created FLINK-31318:
----------------------------------

             Summary: Do not scale down operators while processing backlog
                 Key: FLINK-31318
                 URL: https://issues.apache.org/jira/browse/FLINK-31318
             Project: Flink
          Issue Type: Improvement
          Components: Autoscaler, Kubernetes Operator
            Reporter: Gyula Fora
            Assignee: Gyula Fora


Currently the autoscaler may try to scale down some operators even when the job is struggling to catch up. 

This can lead to a vicious cycle where the backlog keeps increasing. It makes sense to hold off scale down decisions until the job has caught up.
