Redis Cluster及hash slot 算法- 似水牛年- 简书 redis hash slot The CLUSTER SETSLOT command is an important piece used by Redis Cluster in order to migrate all the keys contained in one hash slot from one node to another redis crossslot keys in request don''t hash to the same slot The client sent a command about hash slots never served by the master of this replica The cluster was reconfigured and

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 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 Data Sharding Redis leverages a form of sharding in which every cache key is mapped to a “hash slot ” Within the cluster, there are 16,384 hash
