go - grpc 生成的 stub 线程安全吗？

Question

我正在看grpc的教程 https://grpc.io/docs/tutorials/basic/go.html

grpc 一元调用看起来像这样

conn, err := grpc.Dial(*serverAddr)
if err != nil {
    ...
}
defer conn.Close()
client := pb.NewRouteGuideClient(conn)
feature, err := client.GetFeature(context.Background(), &pb.Point{409146138, -746188906})
if err != nil {
        ...
}

我想知道我是否打电话

   client.GetFeature

来自多个线程，它是线程安全的吗？

调查此 issue你可以了解到:

@rubenv asks:

Can I use a client from different threads in parallel?

@iamqizhao replies:

On client, if you want to perform multiple rpc in parallel, you should spawn multiple goroutines to do that since the rpc is synchronous/blocking

答案是肯定的，但是不能共享流 ( source )。

@trevorgray, these kinds of concurrency topics are apparently still not documented, per #682.
