仔细思考了 Raft 关于配置变更的内容,发现论文中的搞法用代码根本无法实现...然后开始了 search 的阶段,翻到知乎一篇文章和作者的博士论文,感觉用这个可以实现配置变更。 在这里稍微记录一下。 新的发现 知乎作者 孙建良 的一篇 《Raft 一致性协议》 专栏里,提到了 Raft 作者的长达 240 页的博士论文里,关于配...
假设,一个 Raft 服务器集群的数量刚开始是 3 台,过了 2 个月,由于要搞类似 618,双11 大促,领导要增加系统可用性,那么就要增加到 5 台。 如果增加到 5 台,就带来了配置的变化,首当其冲的,就是 “服务器数量” 这个配置的变化,例如这个配置叫做 “server_count = 3”, 你需要将配置改成 “server_coun...
