REDIS CLUSTERING & PARTITIONING FOR BEGINNERS

REDIS CLUSTERING & PARTITIONING FOR BEGINNERS redis hash slot Currently in Redis Cluster mode there are fixed number of slots and the hashing mechanism for the slot is also hardcoded to crc16 redis hash slot Note that normally clients willing to fetch the map between Cluster hash slots and node addresses should use CLUSTER SLOTS instead CLUSTER NODES, that provides

redis hash slot A Redis Cluster is divided into 16384 hash slots, and a deterministic formula is used to derive the key to hash slot mapping, [ CRC16

redis crossslot keys in request don''t hash to the same slot Transactions in Redis only occur within the same hash slot, which ensures the highest throughput  Redis sharding is a method of splitting the keyspace into 16384 hash slots for distribution across nodes It enhances scalability and manages traffic surges,
