URL: https://github.com/apache/dubbo/issues/8307


   
我们测试过2.7.X的服务自身,用dubbo.registry.parameters[registry-type]=service的dubbo服务的确在注册中心只注册一条信息,但是元数据没有dubbo.tag,看资料说consumer要先连接provider获取元数据,我们想在consumer连接provider之前就能根据tag确定要使用的provider,而不是连接provider之后才能确定需要访问的provider在哪儿,以避免出现跨region连接provider,我们感觉2.7.x的服务自省可能不符合我们的需求,或者是我们理解和用法有问题。
   
dubbo3.0推出了全新的基于应用粒度的服务发现机制,但是我们翻遍了https://dubbo.apache.org/zh/docs/v3.0/也没有找到相关的用例或文档说明。
