Apache Dubbo is an easy-to-use, high-performance WEB and RPC framework with builtin service discovery, traffic management, observability, security features, tools and best practices for building enterprise-level microservices.
Dubbo-python is a Python implementation of the triple protocol (a protocol fully compatible with gRPC and friendly to HTTP) and various features designed by Dubbo for constructing microservice architectures.
Visit the official website for more information.
Disclaimer: This project is in the early stages of development. Features are subject to change, and some components may not be fully stable. Contributions and feedback are welcome as the project evolves.
- Service Discovery: Zookeeper
- Load Balance: Random, CPU
- RPC Protocols: Triple(gRPC compatible and HTTP-friendly)
- Transport: asyncio(uvloop)
- Serialization: Customizable(protobuf, json...)
Before you start, make sure you have python 3.9+ installed.
-
Install Directly
pip install apache-dubbo
-
Install from source
git clone https://github.com/apache/dubbo-python.git cd dubbo-python && pip install .
Get up and running with Dubbo-Python in just 5 minutes by following our Quick Start Guide.
It's as simple as the code snippet below. With just a few lines of code, you can launch a fully functional point-to-point RPC service:
-
Build and start the server
import dubbo from dubbo.configs import ServiceConfig from dubbo.proxy.handlers import RpcMethodHandler, RpcServiceHandler class UnaryServiceServicer: def say_hello(self, message: bytes) -> bytes: print(f"Received message from client: {message}") return b"Hello from server" def build_service_handler(): # build a method handler method_handler = RpcMethodHandler.unary( method=UnaryServiceServicer().say_hello, method_name="unary" ) # build a service handler service_handler = RpcServiceHandler( service_name="org.apache.dubbo.samples.HelloWorld", method_handlers=[method_handler], ) return service_handler if __name__ == "__main__": # build service config service_handler = build_service_handler() service_config = ServiceConfig( service_handler=service_handler, host="127.0.0.1", port=50051 ) # start the server server = dubbo.Server(service_config).start() input("Press Enter to stop the server...\n")
-
Build and start the Client
import dubbo from dubbo.configs import ReferenceConfig class UnaryServiceStub: def __init__(self, client: dubbo.Client): self.unary = client.unary(method_name="unary") def say_hello(self, message: bytes) -> bytes: return self.unary(message) if __name__ == "__main__": # Create a client reference_config = ReferenceConfig.from_url( "tri://127.0.0.1:50051/org.apache.dubbo.samples.HelloWorld" ) dubbo_client = dubbo.Client(reference_config) unary_service_stub = UnaryServiceStub(dubbo_client) # Call the remote method result = unary_service_stub.say_hello(b"Hello from client") print(result)
