Redis Cluster: MOVED
hash slot Redis assigns keys to nodes by calculating the hash slot like this: Copy CRC16 mod 16384 CRC16 is a hashing function (
hash slot Every node in a Redis Cluster is responsible for a subset of the hash slots, so for example you may have a cluster with 3 nodes, where: Node A 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(
buitenboordmotor slot 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 I think redis cluster use consistent hashing The hash slots are similar to virtual nodes in consistent hashing Cassandra's data distribution is almost the
