> 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.
> After adding this configuration, even if a large number of jobs failover, it
> does not cause too much pressure on the cluster and has achieved certain
> results
