Question: load balancing in cluster-gateway

[phantomnat]

Hi,

I have 2 questions regarding the load balancing while connecting the managed cluster through cluster-gateway.

First, I'm running 6 kubevela controllers pods (sharding mode) and 4 cluster-gateway pods and noticed that one cluster gateway has high cpu utilization compared to the other.

Should the requests from kubevela spread across all of the cluster-gateway pods?

Second, I found that cluster-gateway only connecting to a single kube-apiserver on the managed cluster.

Should the cluster-gateway connect to all of the servers?

Thank you.
