Redis Cluster multi-key command optimisation with hash tags

There are 16384 hash slots in Redis 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

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