[jira] [Created] (FLINK-22054) Using a shared watcher for ConfigMap
watching
Yi Tang created FLINK-22054:
-------------------------------
Summary: Using a shared watcher for ConfigMap watching
Key: FLINK-22054
URL: https://issues.apache.org/jira/browse/FLINK-22054
Project: Flink
Issue Type: Improvement
Reporter: Yi Tang
While using K8s HA service, the watching for ConfigMap is separate for each job.
This will cost large amounts of connections.
Here we proposal to use a shard watcher for each FlinkKubeClient, and dispatch events to different listeners. At the same time, we should keep the same semantic with watching separately.
