> 熵的概念最早起源于[物理学](https://zh.wikipedia.org/wiki/物理学)，用于度量一个热力学系统的混乱程度。熵最好理解为不确定性的量度而不是确定性的量度，因为越随机的信源的熵越大。

在这里，你可以把反熵中的熵了解为节点之间数据的混乱程度/差异性，反熵就是指消除不同节点中数据的差异，提升节点间数据的相似度，从而降低熵值。

具体是如何反熵的呢？集群中的节点，每隔段时间就随机选择某个其他节点，然后通过互相交换自己的所有数据来消除两者之间的差异，实现数据的最终一致性。

## 4 日志复制

一旦选出了 Leader，它就开始接受客户端的请求。每一个客户端的请求都包含一条需要被复制状态机（`Replicated State Mechine`）执行的命令。
一旦选出了 Leader，它就开始接受客户端的请求。每一个客户端的请求都包含一条需要被复制状态机（`Replicated State Machine`）执行的命令。

Leader 收到客户端请求后，会生成一个 entry，包含`<index,term,cmd>`，再将这个 entry 添加到自己的日志末尾后，向所有的节点广播该 entry，要求其他服务器复制这条 entry。
