[jira] [Created] (FLINK-33598) Watch HA configmap via name instead of lables to reduce pressure on APIserver

Yun Tang created FLINK-33598:
--------------------------------

             Summary: Watch HA configmap via name instead of lables to reduce pressure on APIserver 
                 Key: FLINK-33598
                 URL: https://issues.apache.org/jira/browse/FLINK-33598
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / Kubernetes
    Affects Versions: 1.17.1, 1.18.0
            Reporter: Yun Tang
            Assignee: Yun Tang
             Fix For: 1.19.0, 1.18.1, 1.17.3


As FLINK-24819 described, the k8s API server would receive more pressure when HA is enabled, due to the configmap watching being achieved via filter with labels instead of just querying the configmap name. This could be done after FLINK-24038, which reduced the number of configmaps to only one.
