[jira] [Created] (FLINK-30464) Exclude metrics during stabilization period from the scaling decision

Maximilian Michels created FLINK-30464:
------------------------------------------

             Summary: Exclude metrics during stabilization period from the scaling decision
                 Key: FLINK-30464
                 URL: https://issues.apache.org/jira/browse/FLINK-30464
             Project: Flink
          Issue Type: Bug
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.4.0
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
             Fix For: kubernetes-operator-1.4.0


The current code collects metrics as soon as the job goes into RUNNING mode, regardless of whether we are still in the stabilization period. This means the first metric collection window after rescaling will include metrics from the stabilization period which is not desired. The stabilization period is supposed to allow the job to stabilize and shouldn't be used to make new scaling decisions.
