The 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.

Example #

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:

1. The command only works if all the specified slots are already associated with the node.
2. The command fails if the same slot is specified multiple times.
3. As a side effect of the command execution, the node may go into down state because not all hash slots are covered.

Usage in Redict 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 redict-cli, and mainly exists for API completeness.
