dubbo-3.3.0 Latest

Latest

The Apache Dubbo Team is excited to announce the release of Dubbo 3.3! As a leading open-source microservice framework, Dubbo continues to provide developers with high-performance, scalable, and flexible distributed service solutions. This release introduces the powerful Triple X protocol, support for Native Image AOT, and integration with Project Loom, further optimizing cloud-native capabilities and high-performance scenarios.

Key Features

1. Triple X Protocol

Comprehensive Traffic Support: Triple X seamlessly handles both north-south (client-server) and east-west (service-service) traffic, improving communication efficiency across distributed systems.
gRPC Compatibility: Triple X adheres to the gRPC protocol standard, using Protobuf for communication, enabling smooth interactions with gRPC services.
Built on HTTP: Triple X works with HTTP/1, HTTP/2, and HTTP/3, optimizing network communication for modern cloud-native infrastructures, with robust support for gateways and service meshes.

2. Native Image AOT Support

Faster Startup and Lower Memory Usage: Dubbo 3.3 introduces Native Image AOT (Ahead-of-Time Compilation) support, allowing developers to compile Dubbo applications into native binary files. This dramatically reduces startup times and memory consumption, making it an ideal fit for serverless (e.g., AWS Lambda) scenarios.

3. Project Loom Integration

Optimized Concurrency: Dubbo 3.3 supports Project Loom, enhancing thread management in high-concurrency scenarios through virtual threads. This simplifies asynchronous programming models and boosts concurrent processing capabilities, providing better performance for highly concurrent microservices.

4. Performance Enhancements

High-concurrency Optimization: Triple X achieves notable performance improvements in high-concurrency and weak-network environments, providing better throughput and response times.
Zero Copy Technology: Memory and CPU consumption are reduced with Zero Copy, resulting in higher efficiency in high-load environments.

5. Cloud-native Friendly

HTTP/3 and Cloud Integration: Triple X supports HTTP/3 for enhanced communication, especially in weak-network conditions, and integrates seamlessly with cloud-native service discovery and routing infrastructure.

6. Smooth Migration from Spring Web

Minimal Code Changes: Developers can migrate from existing Spring Web projects to Triple X with minimal code changes, maintaining compatibility with Spring MVC while gaining performance improvements.

Upgrade Guide

To fully leverage the new capabilities in Dubbo 3.3, including Triple X, Native Image AOT, and Project Loom, we recommend upgrading your Dubbo applications.

Explore the new features and experience the improvements in startup speed, memory efficiency, and concurrency performance with Dubbo 3.3.
