Apache Dubbo-go is a high-performance RPC and microservice framework compatible with other Dubbo language implementations. It leverages Golang's concurrency features to provide efficient service governance, including service discovery, load balancing, and traffic management. Dubbo-go supports multiple protocols, such as Dubbo, JSONRPC, Triple(gRPC-compatible), gRPC, HTTP, HTTP2, and HTTP/3 (experimental), ensuring seamless integration in heterogeneous environments.
You can visit the official website for more information.
For detailed changes, refer to CHANGELOG.md.
3.3.1: Optimized configuration hot-reloading with content-based caching to prevent redundant notifications. Added experimental HTTP/3 support, Apollo integration, and Triple protocol OpenAPI generation. Fixed critical race conditions in service discovery under high-concurrency.
3.3.0: Introduced script routing, multi-destination conditional routing, Triple protocol keepalive and connection pooling, Nacos multi-category subscriptions, and enhancements for observability and interoperability.
To install Dubbo-go, use the following command:
go get dubbo.apache.org/dubbo-go/v3@latest
You can learn how to develop a dubbo-go RPC application step by step in 5 minutes by following our Quick Start demo.
It's as simple as the code shown below, you define a service with Protobuf, provide your own service implementation, register it to a server, and start the server.
func (srv *GreetTripleServer) Greet(ctx context.Context, req *greet.GreetRequest) (*greet.GreetResponse, error) {
resp := &greet.GreetResponse{Greeting: req.Name}
return resp, nil
}
func main() {
srv, _ := server.NewServer(
server.WithServerProtocol(
protocol.WithPort(20000),
protocol.WithTriple(),
),
)
_ := greet.RegisterGreetServiceHandler(srv, &GreetTripleServer{})
if err := srv.Serve(); err != nil {
logger.Error(err)
}
}
After the server is up and running, call your service via cURL:
curl \ --header "Content-Type: application/json" \ --data '{"name": "Dubbo"}' \ http://localhost:20000/greet.GreetService/Greet
Or, you can start a standard dubbo-go client to call the service:
func main() {
cli, _ := client.NewClient(
client.WithClientURL("127.0.0.1:20000"),
)
svc, _ := greet.NewGreetService(cli)
resp, _ := svc.Greet(context.Background(), &greet.GreetRequest{Name: "hello world"})
logger.Infof("Greet response: %s", resp.Greeting)
}
See the samples for detailed information on usage. Next, learn how to deploy, monitor and manage the traffic of your dubbo-go application by visiting the official website.
Dubbo-go provides robust service governance capabilities:
The tools/ directory and the dubbogo/tools repository provide several utilities to streamline your Dubbo-Go development experience.
A tool that provides JSON Schema for Dubbo-Go configuration files. This simplifies the configuration process by enabling editor assistance.
Features:
For usage details, see the dubbo-go-schema README.
A comprehensive command-line tool for bootstrapping, managing, and debugging your Dubbo-Go applications.
Features:
A protoc plugin that generates golang code for the Triple protocol from your .proto (Protocol Buffer) definition files.
Features:
protoc-gen-go to produce both Protobuf message code (.pb.go) and Triple interface code (.triple.go).Note: This tool replaces the deprecated protoc-gen-dubbo3grpc and deprecated protoc-gen-go-triple.
For usage details, see the protoc-gen-go-triple README.
This is a plugin for dubbo-go developers. A code formatting tool that organizes golang import blocks according to the Dubbo-Go community style guide.
Features:
import statements into three distinct groups: golang standard library, third-party libraries, and internal project packages.For usage details, see the imports-formatter README.
