尊敬的作者,您好: 在学习您的geecache day4 一致性哈希章节中针对该算法有个疑问,“环上有 peer2,peer4,peer6 三个节点,key11,key2,key27 均映射到 peer2,key23 映射到 peer4。” 这个部分不太理解,当前环上有三个节点的话,key11映射的节点为 11%3=2顺时针映射peer2,key2映射的节点应该 2%3=2顺时针映射peer2,key27映射的节点为27%3=0顺时针映射peer2,key23映射的节点不也应该为23%3=2 peer2 吗? 这个地方一直没搞明白,望您有空点拨下。万分感谢。

是因为定义的哈希函数为 n%10吗?
Sorry, something went wrong.
peer后面跟的字母没有意义,我理解真正起到节点排序作用的是节点名称hash后的值,这里作者可能只是随便写了几个数字,(不然key2两边为什么会有key11和key23),理解作者的意思就好,我和你对一致性hash的理解是一致的
