## 问题描述 registry、config-center、metadata-report 三个角色各自通过 `zookeeper.ValidateZookeeperClient(...)`（来自 `github.com/dubbogo/gost/database/kv/zk`）创建**独立**的 `*gxzookeeper.ZookeeperClient`： - `registry/zookeeper/registry.go` L69 `zookeeper.ValidateZookeeperClient(r, url.Location)` - `config_center/zookeeper/impl.go` L83 `zookeeper.ValidateZookeeperClient(c, url.Location)` - `metadata/report/zookeeper/report.go` L216 `gxzookeeper.NewZookeeperClient(...)` etcd / Nacos 实现同理，各自 new 一套 client。 ## 影响 单个 dubbo-go 应用对**同一个** ZK/etcd/Nacos 集群，同时维持 registry + config-center + metadata-report **三套连接/会话**。连接数与服务端 session 压力 ×3，在大规模部署下客户端连接数可观。 ## 建议修复 - 允许用户注入/共享同一个后端 client（例如通过 `WithXxxClient` option 或全局 client 池），让三个角色复用同一连接； - 或在框架层提供 backend client 工厂，按地址复用单例连接。 ## 参考 - `registry/zookeeper/registry.go` L69 - `config_center/zookeeper/impl.go` L83 - `metadata/report/zookeeper/report.go` L216 -- This is an automated message from the Apache Git Service.
