CAP 理论的提出者布鲁尔在提出 CAP 猜想的时候，并没有详细定义 **Consistency**、**Availability**、**Partition Tolerance** 三个单词的明确定义。

因此，对于 CAP 的民间解读有很多，一般比较被大家推荐的是下面 👇 这种版本的解。

在理论计算机科学中，CAP 定理（CAP theorem）指出对于一个分布式系统来说，当设计读写操作时，只能同时满足以下三点中的两个：

- **一致性（Consistence）** : 所有节点访问同一份最新的数据副本
- **一致性（Consistency）** : 所有节点访问同一份最新的数据副本
- **可用性（Availability）**: 非故障的节点在合理的时间内返回合理的响应（不是错误或者超时的响应）。
- **分区容错性（Partition tolerance）** : 分布式系统出现网络分区的时候，仍然能够对外提供服务。
