-------------------------------
Summary: Reduce the pressure of the list pod method on the k8s
cluster
Key: FLINK-31589
URL: https://issues.apache.org/jira/browse/FLINK-31589
Project: Flink
Issue Type: Improvement
Components: Deployment / Kubernetes
Reporter: liuzhuo
In the production environment, we found that if a cluster-level failure occurs,
the jobs of a cluster will failover at the same time, which puts a lot of
pressure on the k8s cluster.
Through the monitoring of k8s, we found that the method of list pod caused
relatively high pressure.
By querying the relevant information of fabric8, we found an optimization
scheme for the list pod, that is, adding the parameter of
{code:java}
ResourceVersion=0{code}
in the list pod can greatly reduce the pressure on the k8s cluster
