`ReflectionBasedServiceDiscovery#doUnregister` recursion call and no break, looks like a bug. https://github.com/apache/dubbo/blob/c80b79174cd9f8621374728308b5cb87849d4caa/dubbo-registry/dubbo-registry-api/src/main/java/org/apache/dubbo/registry/client/ReflectionBasedServiceDiscovery.java#L187-L193

## What is the purpose of the change 原来为使用redis scan命令来扫描 /dubbo/com.xxx.yyy.XxxService/*的key 按照https://dubbo.apache.org/zh/docsv2.7/user/references/registry/redis/对redis注册中心的介绍 只有/dubbo/com.xxx.yyy.XxxService/providers 和/dubbo/com.xxx.yyy.XxxService/consumers 2种可能性。 在在使用ClusterRedisClient时，scan命令（参考：org.apache.dubbo.remoting.redis.jedis.ClusterRedisClient.scan）是迭代循环所有cluster node 来扫描每一个node，并合并扫描结果完成的，scan命令本来就很慢，使用ClusterRedisClient时会随着节点越多越慢 我的场景中有6个节点，每次需要5 ~ 20秒的扫描时间，每次启动时很慢且卡在初始化reference阶段；或者泛化每接口第一次调用或者硬编码每接口第一次调用时，都会构建Reference，构建reference时花费了很多时间 如果项目中service 接口很多时，有可能在启动或者重启后会导致worker线程阻塞而请求无法正常调用，目前在测试环境已经遇到了该现象，高并发请求时有可能引起雪奔，特别是存在dubbo http网关时的场景。 经过优化后，该场景在开发环境下从5 ~ 20秒性能提升至300~1000ms，提升5 ~ 20倍，基本上在300 ~...
多活场景下，dubbo 调用本地服务时，若本地的实例全部不可用，就需要通过 api 网关把请求转发到其它机房。 dubbo api网关要做以下几件事： 1、本地网关接收 dubbo 协议的调用请求，分析出调用的微服务名称（或接口名称）及参数等信息，之后 api网关按照请求信息找到位于其它机房的 api 网关，转发消息（应该需要转成HTTP 协议，还没深入考虑） 2、dubbo api 网关接收到其它api网关的请求，识别出请求的微服务名称，发送到该微服务的本地实例 ……
