网易的代理方案: 双写其实就是两边发,只是代理层做可以对业务透明,但是不能保证完全对数据一致性的,如果要实现严格一致性 一般都是 逻辑时钟+lastwin 方案。 并发情况下可能乱序: 比如(两个并发的set请求); 可以通过 https://developer.aliyun.com/article/690463 "redis-full-check 校验工具" 检出不同的数据。 |

1 携程 https://blog.csdn.net/zl1zl2zl3/article/details/107392588,逻辑时钟+LASTWIN
2 https://tech.meituan.com/2024/03/15/kv-squirrel-cellar.html 逻辑时钟 + LASTWIN
两个独立的集群绑定了同步关系,两个集群都可以进行读写,且数据互相同步。
3 快手:异步多活, hlc + lastwin
