Scope of datapage

I have 2 picklist properties Country, State which populate list of values. I want to refer both of them to datapages what could be the scope of datapage? I dont want to refer them to RD as it is a performance impact.

Node Level:
If we specify a page in node level, then it can be accessed by all the requestors in the particular node.
Requestor Level:
If we specify a page in Requester level, then it can be accessed by all the threads opened by the requestor.
Thread Level:
If we specify a page in Thread level, then it can be accessed only by that particular thread.

If the State is being filtered based on Country, then you can opt for either node or thread. Select node only of you think the lists are static and wont be updated frequently.

@SohamM95

here both country and state are static values can I choose node?

is there any other option other than data pages for this scenario

@Yasvanth Tanuku

Node should be an inexpensive scope for this. Thread is also another way to go.
