title: Finagle and load balancing
body: <p>I have seen in many places that Finagle has service discovery and load balancing capabilities, but I cannot find any reference to actual detailed implementation.</p>
  <p>How does Finagle client get the address of the Service Discovery?</p>
  <p>How is such a service discovery implemented?</p>
  <p>The documentation seems incomplete...</p>
  <p>Thanks!</p>
