[jira] [Created] (FLINK-34743) Memory tuning takes effect even if the parallelism isn't changed

Rui Fan created FLINK-34743:
-------------------------------

             Summary: Memory tuning takes effect even if the parallelism isn't changed
                 Key: FLINK-34743
                 URL: https://issues.apache.org/jira/browse/FLINK-34743
             Project: Flink
          Issue Type: Improvement
          Components: Autoscaler
            Reporter: Rui Fan
            Assignee: Rui Fan
             Fix For: kubernetes-operator-1.9.0


Currently, the memory tuning related logic is only called when the parallelism is changed.

See ScalingExecutor#scaleResource to get more details.

It's better to let the memory tuning takes effect even if the parallelism isn't changed. For example, one flink job runs with desired parallelisms, but it wastes memory.
