A replacement for groupcache HTTPPool that uses GRPC to communicate with peers.
server := grpc.NewServer()
p := NewGRPCPool("127.0.0.1:5000", server)
p.Set(peerAddrs...)
getter := groupcache.GetterFunc(func(ctx groupcache.Context, key string, dest groupcache.Sink) error {
dest.SetString(...)
return nil
})
groupcache.NewGroup("grpcPool", 1<<20, getter)
lis, err := net.Listen("tcp", "127.0.0.1:5000")
if err != nil {
log.Fatalf("Failed to start server")
}
server.Serve(lis)Use GRPCPoolOptions to set the GRPC client dial options such as using compression, authentication etc.
