) "> Consistent hash Algorithm (Consistent hashing) Zhang Liang The consistent hashing algorithm was first published in 1997.Consistent hashing and random treesHas been proposed, and is widely used in the cache system; 1. Basic scenarios For

One: HashMap before talking about consistent hashing, first review hashmap. When using HashMap, the key is mapped evenly into the HashMap internal array (Entry ""), and the mapping method uses the hash value of key to do the shift operation. And the

Consistent hashAlgorithmKarger and others at the Massachusetts Institute of Technology proposed in 1997 to solve the distributed cache. The design goal was to solve the hot spot issue on the Internet. The original intention was very similar to carp.
