| traffic management | adaptive load balance | 基于 Provider 的 CPU、RT、inflight 等指标动态选择实例。参考：[Dubbo 自适应负载均衡](https://cn.dubbo.apache.org/zh-cn/overview/reference/proposals/heuristic-flow-control/)、[Kitex 负载均衡](https://www.cloudwego.io/zh/docs/kitex/tutorials/service-governance/loadbalance/) | |
| traffic | adaptive rate limit | 根据 Provider 实际负载动态调整最大并发数并进行过载保护。参考：[Dubbo 自适应限流](https://cn.dubbo.apache.org/zh-cn/overview/manual/java-sdk/tasks/rate-limit/adaptive-concurrency-control/)、[Uber Cinnamon Auto-Tuner](https://www.uber.com/us/en/blog/cinnamon-auto-tuner-adaptive-concurrency-in-the-wild/)、[Netflix concurrency-limits](https://github.com/Netflix/concurrency-limits) | [#3336](https://github.com/apache/dubbo-go/issues/3336) |
| | load shedding | 根据请求优先级、服务和方法维度进行过载拒绝和降级。参考：[字节 KubeGateway](https://developer.volcengine.com/articles/7317093789460332570)、[Netflix Prioritized Load Shedding](https://netflixtechblog.com/enhancing-netflix-reliability-with-service-level-prioritized-load-shedding-e735e6ce8f7d) | |
| refactoring | metadata | 重构本地 Metadata、MetadataService、MetadataReport 和 Service Discovery 的边界。参考：[Nacos](https://github.com/alibaba/nacos)、[Dubbo Metadata](https://dubbo.apache.org/zh-cn/overview/what-is-dubbo/metadata/) | working in [#3188](https://github.com/apache/dubbo-go/issues/3188) |
| | registry | 统一 Registry 与 ServiceDiscovery 模型，完善事件、缓存和多注册中心支持。参考：[Nacos](https://nacos.io/zh-cn/)、[Dubbo Registry](https://dubbo.apache.org/zh-cn/overview/what/) | |
