吐槽下Nacos服务发现

Posted 2022-02-01 流子

1.注销实例的API或者SDK（deregisterInstance）,会导致该条记录消失，如果只是modifyinstance,会导致永远驻留在数据中

2.游戏区做了迁移或者IP漂移的话，老的脏数据还是会在服务器列表里，没法通过zoneid去覆盖，只能通过人工去把该节点下线

3.目前为了减少线程占用，dir和game的底层用的是nacos API，基于http client封装，但为了实时同步（subscribe），dir服又同时用了nacos SDK

4.用Nacos SDK 的话，进程会新增10几个线程

5.每次有区服更新，会导致全量同步

6. 同步时冗余数据过多
