--------------------------------
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.
