Web本文主要介绍分布式数据存储的核心算法,也就是数据分布的算法,主要包含:hash算法 、一致性hash算法(memcached) 以及redis cluster中使用的hash slot算法。 数据分布其实就是数据如何分布到多个不同的节点 … WebRedis 集群没有使用一致性hash, 而是引入了哈希槽的概念。 Redis 集群有 16384 个哈希槽,每个key通过CRC16校验后对16384取模来决定放置哪个槽.集群的每个节点负责一部分hash槽。这种结构很容易添加或者删除节点,并且无论是添加删除或者修改某一个节点,都 … mithya zee5 release date
hash算法、一致性hash算法以及hash slot算法的简单介绍
WebThe advanced feature is called key hash tag, and it works like this: if instead of using "user:1:friends" you use " {foo}user:1:friends", then Redis Cluster will only use the substring "foo" in order to compute the hash. So all keys with they hash tag {foo} will end up in the same hash slot, and you will be able to run multi-key operations on ...
