safe with slot Redis Cluster does not use consistent hashing but a different form of data split with every key being a part of what is called a hash slot

The CLUSTER SETSLOT command is an important piece used by Redis Cluster in order to migrate all the keys contained in one hash slot from one node to another

redis crossslot keys in request don''t hash to the same slot There are 16384 hash slots in KeyDB Cluster, and to compute what is the hash slot of a given key, we simply take the CRC16 of the key modulo 16384 Every node

There are 16384 hash slots in Redis Cluster, and to compute the hash slot The user can force multiple keys to be part of the same hash slot by using a feature
