Google Summer of Code 2024: Traffic Management for Dubbo-go and Dubbo-k8s - Feature Enhancement and Demonstration

Project Goal

The primary objective of this project is to improve and enhance the traffic management capabilities of Dubbo. This involves adding more comprehensive routing functionality to Dubbo-go, extending traffic control support in Dubbo-k8s, introducing service mesh traffic management capabilities to Dubbo, and integrating an xDS configuration module.

My Contributions (Pull Requests)

1. Script-based Routing in Dubbo-go: Implemented a new feature that allows the construction of routing rules based on scripts within Dubbo-go.
2. Upgraded Conditional Routing in Dubbo-go: Enhanced the existing conditional routing feature in Dubbo-go to offer more sophisticated and flexible routing conditions.
3. Configuration and Implementation in Dubbo-k8s Admin Section: Developed the configuration settings and implemented the writing mechanism for the admin section of Dubbo-k8s.
4. Scenario-based Configuration for Applications, Services, and Instances in Dubbo-k8s: Designed and implemented scenario-based configuration settings for applications, services, and instances within the admin section of Dubbo-k8s.
5. xDS Module Integration in Dubbo-k8s: Introduced the xDS module in Dubbo-k8s by integrating virtual service and destination rule functionalities, enabling the generation of xDS protocol data from traffic management rules.
