title: GRPC loadbalancer example
body: <p>I am trying to build server set management mechanism with load balancing using GRPC/Java. </p>
  
  <p>By looking at the API doc, there are classes like:
  LoadBalancer, RoundRobinLoadBalancerFactory, etc. </p>
  
  <p>By looking at the names, it seems like they should do what I want to do. 
  However, I couldn't find any code examples using these class even I googled very hard. </p>
  
  <p>On the other hand, I found some Finagle/Thrift examples like this: <a href="https://github.com/benjumanji/finagle-serverset-example" rel="nofollow noreferrer">https://github.com/benjumanji/finagle-serverset-example</a></p>
  
  <p>I am wondering if anyone can share some working GRPC examples? Thanks!</p>
