Mastering Redis Clustering: A Comprehensive Guide

Redis Cluster doesn't use consistent hashing to do the distribution job Instead, it uses the hash slots Each cluster has 16384 hash slots that

Keys are partitioned using the concept of hash slots, of which there are 16384 in total, distributed across the cluster's nodes For example, if

redis hash slot Transactions in Redis only occur within the same hash slot, which ensures the highest throughput

redis crossslot keys in request don''t hash to the same slot The single key or multi-key operation must belong to the same hash slot of the shard By default, replica nodes with cluster mode turned on redirect all read
