- To create a new cluster,
CLUSTER ADDSLOTSRANGEis used to initially set up primary nodes splitting the available hash slots among them. - In order to fix a broken cluster where certain slots are unassigned.
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
