[GitHub] [dubbo] AlbumenJ commented on issue #8307: 有没有dubbo3.0全新的基于应用粒度的服务发现机制支持TagRouter的例子或文档？

   > 我们测试过2.7.X的服务自省，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。
   
   可以使用中心化的元数据中心避免跨region连接
