Upgrade Process
Upgrading the operator won't affect the cluster.
Upgrading the Terraform script (and apply the upgraded version) won't affect the existing nodes, but the configuration of tidb-servers will be changed. Therefore, a rolling-update of tidb-servers will be triggered.
If you want to enable server-side tcp keepalive on an existing cluster, you have to manually release the EC2 instances in which the tidb-servers running to get them re-created using the new tcp_keepalived configuration.
