Redis Cluster通过hash slot映射数据 - 稀土掘金 redis hash slot All 16384 slots covered After creating the cluster there are 16384 hash slots, divided by the 3 servers: Server 1 contains hash slots from 0 to redis hash slot The Redis cluster has 16384 hash slots Each key is checked modulo 16384 after CRC16 verification to determine which slot to place Each node in the cluster is

redis hash slot So how are keys related to slots? These slots are actually hash slots, in which each key is put through a hashing function to mathematically

redis crossslot keys in request don''t hash to the same slot  now redis-cli -h -p 6379 cluster nodes should show you all nodes 3 Divide range of hash slots into equal parts and assign it to Redis sharded data automatically into the servers Redis has a concept of hash slot in order to split data All the data are divided into slots There are 16384
