Hash Tagging Redis Keys in a Clustered Environment

Redis Cluster does not use consistent hashing, but a different form of sharding where every key is assigned to something called a hash slot

indo slot 388 hash-slot> IMPORTING source-id>: This subcommand changes the hash slot state to importing It must be executed at the node that is going to receive the hash

hash 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

Given a hashing table T with m slots, we want to store n = S keys, as maximum Important measure: load factor α = nm, the average number of keys per slot
