base on The java implementation of Apache Dubbo. An RPC and microservice framework. # Apache Dubbo Project [](https://github.com/apache/dubbo/actions/workflows/build-and-test-pr.yml) [](https://codecov.io/gh/apache/dubbo)   [](http://isitmaintained.com/project/apache/dubbo "Average time to resolve an issue") [](http://isitmaintained.com/project/apache/dubbo "Percentage of issues still open") Apache Dubbo is an easy-to-use Web and RPC framework that provides multiple language implementations(Java, [Go](https://github.com/apache/dubbo-go), [Rust](https://github.com/apache/dubbo-rust), [Node.js](https://github.com/apache/dubbo-js), [Web](https://github.com/apache/dubbo-js)) for communication, service discovery, traffic management, observability, security, tools, and best practices for building enterprise-ready microservices. We are now collecting Dubbo user info to help us to improve Dubbo further. Kindly support us by providing your usage information on [Wanted: who's using dubbo](https://github.com/apache/dubbo/discussions/13842), thanks :) ## Architecture  * Consumer and provider communicate with each other using RPC protocol like triple, tcp, rest, etc. * Consumers automatically trace provider instances registered in registries(Zookeeper, Nacos) and distribute traffic among them by following traffic strategies. * Rich features for monitoring and managing the cluster with dynamic configuration, metrics, tracing, security, and visualized console. ## Getting started Follow the instructions below to learn how to: ### Programming with lightweight RPC API [5 minutes step-by-step guide](https://dubbo.apache.org/zh-cn/overview/quickstart/rpc/java) Dubbo supports building RPC services with only a few lines of code while depending only on a lightweight SDK (<10MB). The protocol on the wire can be [Triple](https://dubbo.apache.org/zh-cn/overview/reference/protocols/triple/)(fully gRPC compatible and HTTP-friendly), Dubbo2(TCP), REST, or any protocol of your choice. ### Building a microservice application with Spring Boot [5 minutes step-by-step guide](https://dubbo.apache.org/zh-cn/overview/quickstart/microservice) It's highly recommended to start your microservice application with the Spring Boot Starter `dubbo-spring-boot-starter` provided by Dubbo. With only a single dependency and yaml file, and optionally a bunch of other useful spring boot starters, you can enable all of the Dubo features like service discovery, observability, tracing, etc. Next, learn how to [deploy](https://dubbo.apache.org/zh-cn/overview/tasks/deploy/), [monitor](https://dubbo.apache.org/zh-cn/overview/tasks/observability/), and [manage the traffic](https://dubbo.apache.org/zh-cn/overview/tasks/traffic-management/) of your Dubbo application and cluster. ## More Features Get more details by visiting the links below to get your hands dirty with some well-designed tasks on our website. * [Launch a Dubbo project](https://dubbo.apache.org/zh-cn/overview/tasks/develop/template/) * [RPC protocols](https://dubbo.apache.org/zh-cn/overview/core-features/protocols/) * [Traffic management](https://dubbo.apache.org/zh-cn/overview/core-features/traffic/) * [Service discovery](https://dubbo.apache.org/zh-cn/overview/core-features/service-discovery/) * [Observability](https://dubbo.apache.org/zh-cn/overview/core-features/observability/) * [Extensibility](https://dubbo.apache.org/zh-cn/overview/core-features/extensibility/) * [Security](https://dubbo.apache.org/zh-cn/overview/core-features/security/) * [Visualized console and control plane](https://dubbo.apache.org/zh-cn/overview/reference/admin/) * [Kubernetes and Service mesh](https://dubbo.apache.org/zh-cn/overview/core-features/service-mesh/) ## Which Dubbo version should I use? | **Dubbo3** | **JDK** | **Dependencies** | **Description** | | --- | --- | --- | --- | | 3.3.0-beta| 1.8 ～ 17 | [dependency list](https://github.com/apache/dubbo/blob/3.3/dubbo-dependencies-bom/pom.xml#L94) | **- Unstable version** <br/> **- Features** <br/> &nbsp;&nbsp; - Triple - gRPC and cURL compatible.<br/> &nbsp;&nbsp; - Rest-style programming support.<br/> &nbsp;&nbsp; - Spring Boot Starters. | | 3.2.5 | 1.8 ～ 17 | [dependency list](https://github.com/apache/dubbo/blob/dubbo-3.2.5/dubbo-dependencies-bom/pom.xml#L94) | **- Stable version (active)** <br/> **- Features** <br/> &nbsp;&nbsp;- Out-of-box metrics and tracing support.<br/> &nbsp;&nbsp;- Threadpool Isolation<br/> &nbsp;&nbsp;- 30% performance<br/> &nbsp;&nbsp;- Native Image| | 3.1.11 | 1.8 ～ 11 | [dependency list](https://github.com/apache/dubbo/blob/dubbo-3.2.11/dubbo-dependencies-bom/pom.xml#L94) | **Stable version (not active)** | | **Dubbo2** | **JDK** | **Dependencies** | **Description** | | --- | --- | --- | --- | | 2.7.23 | 1.8 | [dependency list](https://github.com/apache/dubbo/blob/dubbo-2.7.23/dubbo-dependencies-bom/pom.xml#L92) | EOL | | 2.6.x, 2.5.x | 1.6 ～ 1.7 | | EOL | ## Contributing See [CONTRIBUTING](https://github.com/apache/dubbo/blob/master/CONTRIBUTING.md) for details on submitting patches and the contribution workflow. ### How does the Dubbo Community collaborate? The Dubbo Community primarily communicates on GitHub through issues, discussions, and pull requests. - Issues: We use issues to track bugs and tasks. Any **work-related** item is associated with an issue. - Discussions: We use discussions for questions, early proposals, and announcements. Any **idea-related** item is associated with a discussion. - Pull Requests: We use pull requests to merge a set of changes from contributors into Dubbo. We have also implemented [a project board](https://github.com/orgs/apache/projects/337) to monitor all the items. Any essential changes should be discussed on the mailing list before they happen. ### Seeking for help If you have questions such as: - What is Dubbo? - How do I use Dubbo? - Why did an unexpected result occur? Please start a discussion at https://github.com/apache/dubbo/discussions. However, if you encounter the following situations: - You're certain there's a bug that Dubbo needs to fix, - You believe a feature could be enhanced, - You have a detailed proposal for improving Dubbo, Please open an issue at https://github.com/apache/dubbo/issues.
