In version 3.x of Dubbo, to maintain compatibility with the older 2.x versions, Dubbo adopted a dual registration method during service migration, registering services both at the interface level and the application level. This is why the number of connections appears to be doubled. you can see the explain in [chinese version](https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/upgrades-and-compatibility/service-discovery/migration-service-discovery/) or [english version](https://cn.dubbo.apache.org/en/overview/tasks/migration/service-discovery-samples/) . You can find the details of the interface-level services in the ZooKeeper path `/dubbo/com.example.ProductService/providers`, and the details of the application-level services under the ZooKeeper path `/dubbo/metadata/ProductApp`.In ZooKeeper, you can indeed see that the specific number of connections is 7. -- This is an automated message from the Apache Git Service.
