golang async GRPC example

[ltum...@gmail.com]

Hi,
The benchmark results on the grpc.io website show that golang's Sync qps performance is about half that of Java Async's.
- Please share any benchmarks done on Golang Async grpc.
- Also please share any sample code how to do Async Grpc in golang.

Thanks
Lax

Hey Lax,

There's only a sync implementation of gRPC in golang.

Best,
