- Usage:
CLUSTER ADDSLOTSRANGE start-slot end-slot [ start-slot end-slot ...]
- Complexity:
- O(N) where N is the total number of the slots between the start slot and end slot arguments.
- Since:
- 7.0.0
The CLUSTER ADDSLOTSRANGE
is similar to the CLUSTER ADDSLOTS
command in that they both assign hash slots to nodes.
The difference between the two commands is that CLUSTER ADDSLOTS
takes a list of slots to assign to the node, while CLUSTER ADDSLOTSRANGE
takes a list of slot ranges (specified by start and end slots) to assign to the node.
Example
To assign slots 1 2 3 4 5 to the node, the CLUSTER ADDSLOTS
command is:
> CLUSTER ADDSLOTS 1 2 3 4 5
OK
The same operation can be completed with the following CLUSTER ADDSLOTSRANGE
command:
> CLUSTER ADDSLOTSRANGE 1 5
OK
Usage in Valkey Cluster
This command only works in cluster mode and is useful in the following Valkey Cluster operations:
- To create a new cluster,
CLUSTER ADDSLOTSRANGE
is used to initially set up master nodes splitting the available hash slots among them. - In order to fix a broken cluster where certain slots are unassigned.
