CLUSTER DELSLOTSRANGE start-slot end-slot [start-slot end-slot ...]
- Available since:
- Time complexity:
- O(N) where N is the total number of the slots between the start slot and end slot arguments.
- ACL categories:
CLUSTER DELSLOTSRANGE command is similar to the
CLUSTER DELSLOTS command in that they both remove hash slots from the node.
The difference is that
CLUSTER DELSLOTS takes a list of hash slots to remove from the node, while
CLUSTER DELSLOTSRANGE takes a list of slot ranges (specified by start and end slots) to remove from the node.
To remove slots 1 2 3 4 5 from the node, the
CLUSTER DELSLOTS command is:
> CLUSTER DELSLOTS 1 2 3 4 5 OK
The same operation can be completed with the following
CLUSTER DELSLOTSRANGE command:
> CLUSTER DELSLOTSRANGE 1 5 OK
However, note that:
- The command only works if all the specified slots are already associated with the node.
- The command fails if the same slot is specified multiple times.
- As a side effect of the command execution, the node may go into down state because not all hash slots are covered.
Usage in Redis Cluster
This command only works in cluster mode and may be useful for
debugging and in order to manually orchestrate a cluster configuration
when a new cluster is created. It is currently not used by
and mainly exists for API completeness.
Simple string reply:
OK if the command was successful. Otherwise
an error is returned.
