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.

• Go 1.24 or later (recommended for compatibility with recent updates).

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:

• RPC Protocols: Triple, gRPC compatible and HTTP-friendly
• Service Discovery: Nacos, Zookeeper, Etcd, Polaris-mesh.
• Load Balance: Adaptive, Random, RoundRobin, LeastActive, ConsistentHash
• Traffic Management: traffic split, timeout, rate limiting, canary release
• Configuration: yaml file, dynamic configuration(Nacos, Apollo, Zookeeper, etc.).
• Observability: Metrics (Prometheus), tracing (OpenTelemetry v1.21.0+ with insecure options and standardized span names), logging (with service registration lifecycle events).
• HA Strategy: Failover, Failfast, Failsafe/Failback, Available, Broadcast, Forking.
• Interoperability: Full compatibility with Apache Dubbo (Java) via Triple protocol generic calls, group/version wildcard matching, and TLS API redesign.

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:

• Intelligent Assistance: Enables code completion, hints, and real-time validation for configuration files in supported IDEs.
• Simplified Configuration: Helps you write valid and accurate configurations with ease.

For usage details, see the dubbo-go-schema README.

A comprehensive command-line tool for bootstrapping, managing, and debugging your Dubbo-Go applications.

Features:

• Project Scaffolding: Quickly create new application templates.
• Tool Management: Install and manage essential development tools.
• Interface Debugging: Provides commands to debug your services.

• dubbogo-cli
• dubbogo-cli-v2

A protoc plugin that generates golang code for the Triple protocol from your .proto (Protocol Buffer) definition files.

Features:

• Code Generation: Generates golang client and server stubs for the Triple protocol.
• Seamless Integration: Works alongside the official 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:

• Automatic Formatting: Splits import statements into three distinct groups: golang standard library, third-party libraries, and internal project packages.
• Code Consistency: Enforces a clean and consistent import style across the codebase.

For usage details, see the imports-formatter README.
