redis hash slot A Redis® Cluster is divided into 16384 hash slots, and a deterministic formula is used to derive the key to hash slot mapping, that is [ CRC16( But in this example we'll assume they are just ten, from 0 to 9 ;) Different nodes will hold a subset of hash slots A given key foo is at slot: slot = crc16 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
