This PR implements automatic rebalance after pika cluster expansion. The specific verification method is as follows:

  1. Upgrade or update kubeblocks to 0.7.1-beta.1
# install
kbcli kubeblocks install --version 0.7.1-beta.1

# or upgrade
kbcli kubeblocks upgrade --version 0.7.1-beta.1
  1. Install the cluster
helm install pika ./pika && helm install pika-cluster ./pika-cluster
  1. Verify the cluster status
kubectl port-forward svc/pika-cluster-codis-fe 8080

Open codis-fe at http://127.0.0.1:8080/, and you can see the cluster has automatically rebalanced.

  1. Scale out
    First, edit pika-cluster/values.yaml to increase replicaCount.
    Then upgrade the cluster.
helm upgrade pika-cluster ./pika-cluster
  1. Verify the cluster status
    Observe the cluster status on codis-fe, and you can see the cluster rebalances again.
