我们用C实现了一个 gRPC 的域名解析插件（在grpc_plugin_registry.c里面注册），这个插件根据域名去zookeeper上找某个角色对应的ip和端口。当这个角色重启后，如果它是在其他机器上启动的，我们修改zk上的ip端口信息。此时，gRPC 却还是按照老的ip端口对它进行解析。我们期望 gRPC 能够在连接老的ip和端口失败N次后重新调用域名解析，解析到新的ip和端口。请问一下 gRPC 有办法实现吗？
We use C to achieve a gRPC domain name resolution plugin (register in grpc_plugin_registry.c), the plugin search the IP and port of one role in zookeeper. When this role is restarted, if it is started on other machines, we modify the IP port information on the ZK. At this point, gRPC is using the old IP port. We expect gRPC to be able to reconcile domain name resolution, parsing to new IPs and ports after connecting old IP and port failures n times. Will gRPC have a way to achieve it?
