Vtctld Server API

We are thrilled to discuss VtctldServer, the new gRPC API for performing cluster management operations with vtctld components. This is the (near-) culmination of long, steady migration that began back in Vitess v9 (!!!) and went GA in Vitess v15, so we’d like to talk a bit about the motivation behind the move, the design of the new API, and where we go from here. Why? # Vitess users may have found themselves invoking various cluster management operations (think CreateKeyspace, EmergencyReparentShard, Backup, and so on) via the vtctlclient program.
