Functions

func Spec

Spec returns a configuration specification for the round-robin peer list implementation, making it possible to select the least recently chosen peer with transports that use outbound peer list configuration (like HTTP).

cfg := yarpcconfig.New()
cfg.MustRegisterPeerList(roundrobin.Spec())

This enables the round-robin peer list:

outbounds:
  otherservice:
    unary:
      http:
        url: https://host:port/rpc
        round-robin:
          peers:
            - 127.0.0.1:8080
            - 127.0.0.1:8081
