Service Discovery & Configuration through xDS

题目3 - Service Discovery & Configuration through xDS

支持基于 xDS 的服务发现、服务配置，使得 Dubbo 可直接与 Mesh 架构的控制面通信

背景

xDS 是 Mesh 架构下定义的一套服务配置下发的通用协议，最开始来自于 Envoy，用于实现控制面与数据面的数据/配置下发。xDS 是一系列配置 API 的统称：

• Listener Discovery Service (LDS): Returns Listener resources. Used basically as a convenient root for the gRPC client's configuration. Points to the RouteConfiguration.
• Route Discovery Service (RDS): Returns RouteConfiguration resources. Provides data used to populate the gRPC service config. Points to the Cluster.
• Cluster Discovery Service (CDS): Returns Cluster resources. Configures things like load balancing policy and load reporting. Points to the ClusterLoadAssignment.
• Endpoint Discovery Service (EDS): Returns ClusterLoadAssignment resources. Configures the set of endpoints (backend servers) to load balance across and may tell the client to drop requests.

实现方案（目标）

主要是 Client 端对接 xDS 协议

• 实现基于 xDS 的服务发现
• 实现基于 xDS 的配置和规则下发

Hello sir,

I am Ronnie Gandhi, a Computer Science undergraduate student from IIT Roorkee enrolled in my pre-final year.

I am interested in working on this project. I have learnt networking and worked on fundamental concepts including the protocols as a part of my academic course curriculum. I can pick up any language of code quite easily. I would like to work on your project please inform me about how any specific things needed that might be helpful for the project.

A brief introduction about me, I have interned at Microsoft, Hyderabad in 2019 and I am currently interning there(remotely) as well in 2020 also I have done GSoC2019 under CGAL. I am really enthusiastic about contributing to the open-source community.

Sorry @RonnieGandhi , I missed your comment. We are about to start this project recently, please let me know if you are still interested.

what's the current status of supportinh xDS protocal-based service discovery & configuraiton.? (seems issue is still open)

what's the relationship between this issue and this code commit: https://github.com/apache/dubbo/pull/7112/commits
