redisexceptionsresponseerror_ crossslot keys in request don''t hash to the same slot Redis supports multi-key commands in Cluster Mode, such as Set type unions or intersections, mset and mget, as long as the keys all hash to the same slot

redis hash slot slot One shard can contain many hash slots, and a hash slot contains many keys The total number of hash slots in a database is always 16384 ( 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
