声明要关心的服务及相关的地址列表，相比于拉取/订阅全量地址列表，这样做有很好的性能优势。
在应用级服务发现模型中，想做到精确地址订阅并不容易，因为 Dubbo Consumer 只声明了要消费的接口列表，Consumer 需要能够将接口转换为
Provider 应用名才能进行精准服务订阅，</p><p>为此，Dubbo 需要在元数据中心维护这一份 <code>接口名->应用名</code>
的对应关系，Dubbo3 中通过 provider 启动的时候主动向元数据中心上报实现。
接口 (service name) - 应用 (Provider application name) 的映射关系可以是一对多的，即一个 service
name 可能会对应多个不同的 application name。</p><p>以 zookeeper 为例，映射关系保存在以下位置:</p><div
