Nacos 架构 1. Nacos 提供可视化的控制台，可以对配置进行发布、更新、删除、灰度、版本管理等功能。 2. SDK 可以提供发布配置、更新配置、监听配置等功能。 3. SDK 通过 GRPC 长连接监听配置变更，Server 端对比 Client 端配置的 MD5 和本地 MD5 是否相等，不相等推送配置变更。 4. SDK 会保存配置的快照，当服务端出现问题的时候从本地获取。 间连接数及负载自动计算节点合理连接数，自 动触发 reblance，自动削峰填谷。实现周期较长，比较依赖算法准确性。 3. 连接⽣命周期 心跳保活机制 Nacos 架构 < 48 类型 TCP netty mina grpc rsocket tb remote 心跳保活机制 keepalive 机 制：通道无读 写事件时，发 送心跳包检 测，可设置超 时时间，间隔 次数 1.设置 TCP 参数 2 自定义心 跳，有事件 通知 参考：理解 TCP Keepalive： https://blog.csdn.net/chrisnotfound/article/details/80111559 grpc keepalive ：https://blog.csdn.net/zhaominpro/article/details/103127023 netty 的心跳检测：https://www.cnblogs
