[java] how to implement load balance in grpc.

[kuizh...@gmail.com]

Nowadays,I'm studing grpc. I've read the doc on the github.  http://https://github.com/grpc/grpc/blob/master/doc/load-balancing.md  But i don't find an example about how to load balance in grpc.It would be appreciated if anyone could give me an example

Load Balancing comes in two parts: 

1.  The local load balancing logic

2.  The load balancing service that keeps track of all the servers you want to talk to.

I can't speak much about 2, but for 1 the logic in RoundRobinLoadBalancerFactory is a good example of how to implement your own load balancing logic.

Thank you for your reply.

I still have no idea about it. I don't konw what should to do in grpc client and server.I read the example github.com/saturnism/grpc-java-demos/tree/master/kubernetes-lb-example

In that example ,they create  NameResolver and NameResolverProvider.Do you have a simple grpc load balance example that includes  client and server.

Let's step back.  High level, what do you want to do?
