gorpc

A simple, easy to use, high performance, pluggable micro services framework

English | Chinese

Installation

Before installing gorpc, you need to install go and configure the go environment

In gopath mode, you simply execute the following command to install

go get -u -v github.com/lubanproj/gorpc

In the go modules mode, you simply import the package "github.com/lubanproj/gorpc", which automatically downloads the dependency when you execute the go [build|run|test]

Quick Start

git clone https://github.com/lubanproj/gorpc.git
cd gorpc/examples/helloworld
# start server
go run server/server.go
# start client，start another terminal and execute
go run client/client.go

Example

You only need three steps to complete a service call

1. define a service
2. use a server to publish a service
3. use a client to initiate a service call

1. define a service

type Service struct {

}

type HelloRequest struct {
	Msg string
}

type HelloReply struct {
	Msg string
}

func (s *Service) SayHello(ctx context.Context, req *HelloRequest) (*HelloReply, error) {
	rsp := &HelloReply{
		Msg : "world",
	}

	return rsp, nil
}

2. use a server to publish a service

func main() {
	opts := []gorpc.ServerOption{
		gorpc.WithAddress("127.0.0.1:8000"),
		gorpc.WithNetwork("tcp"),
		gorpc.WithSerializationType("msgpack"),
		gorpc.WithTimeout(time.Millisecond * 2000),
	}
	s := gorpc.NewServer(opts ...)
	if err := s.RegisterService("/helloworld.Greeter", new(helloworld.Service)); err != nil {
		panic(err)
	}
	s.Serve()
}

3. use a client to initiate a service call

func main() {
	opts := []client.Option {
		client.WithTarget("127.0.0.1:8000"),
		client.WithNetwork("tcp"),
		client.WithTimeout(2000 * time.Millisecond),
		client.WithSerializationType("msgpack"),
	}
	c := client.DefaultClient
	req := &helloworld.HelloRequest{
		Msg: "hello",
	}
	rsp := &helloworld.HelloReply{}
	err := c.Call(context.Background(), "/helloworld.Greeter/SayHello", req, rsp, opts ...)
	fmt.Println(rsp.Msg, err)
}

• CPU cores : 8
• Memory : 16G
• Disk : 540G

Result : The results were performed using gorpc-benchmark ，which performed three times to get the maximum

gorpc :

git clone https://github.com/lubanproj/gorpc-benchmark.git
cd gorpc-benchmark
# start gorpc server
go run server.go
# start gorpc-benchmark client，start another terminal and execute
go run client.go -concurrency=100 -total=1000000

The performance test results are as follows :

grpc :

Test grpc with the same machine :

git clone https://github.com/lubanproj/gorpc-benchmark.git
cd gorpc-benchmark/grpc
# run gorpc server
go run server.go
# run gorpc-benchmark client, start another terminal and execute 
go run client.go -concurrency=100 -total=1000000

The performance test results are as follows :
