示例1: forward
// forward is used to forward to a remote region or to forward to the local leader
// Returns a bool of if forwarding was performed, as well as any error
func (s *Server) forward(method string, info structs.RPCInfo, args interface{}, reply interface{}) (bool, error) {
var firstCheck time.Time
region := info.RequestRegion()
if region == "" {
return true, fmt.Errorf("missing target RPC")
}
// Handle region forwarding
if region != s.config.Region {
err := s.forwardRegion(region, method, args, reply)
return true, err
}
// Check if we can allow a stale read
if info.IsRead() && info.AllowStaleRead() {
return false, nil
}
CHECK_LEADER:
// Find the leader
isLeader, remoteServer := s.getLeader()
// Handle the case we are the leader
