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
