CLUSTER DELSLOTS slot [slot ...]

Available since 3.0.0.

Time complexity: O(N) where N is the total number of hash slot arguments

In Redis Cluster, each node keeps track of which master is serving a particular hash slot.

The DELSLOTS command asks a particular Redis Cluster node to forget which master is serving the hash slots specified as arguments.

In the context of a node that has received a DELSLOTS command and has consequently removed the associations for the passed hash slots, we say those hash slots are unbound. Note that the existence of unbound hash slots occurs naturally when a node has not been configured to handle them (something that can be done with the ADDSLOTS command) and if it has not received any information about who owns those hash slots (something that it can learn from heartbeat
