• rpc GetMinTS (GetMinTSRequest, GetMinTSResponse)

  tsopb.proto:25

  Get the minimum timestamp across all keyspace groups served by the TSO server who receives and handle the request. If the TSO server/pod is not serving any keyspace group, return an empty timestamp, and the client needs to skip the empty timestamps when collecting the min timestamp from all TSO servers/pods.
