Voldemort collections problem (VStack/VLinkedPageList)

[Tom Finn]

Hi

I found this article about collections operations on voldemort stores, but I am having problems understanding how to actually use it. I think the article does nto describe it that well, except for a on very small code sample.

When trying to use the VStack class, the constructor requires two Maps, one for the key and one for the value, which to me makes no sense. Any hints or explanations how that works?

Basically, what I want to be able to do is iterate over alle the keys in a store or preferably be able to access the keys in FIFO type order. I understand the collections can help with this, but I dont quite understand how its meant to solve that problem.

Any thoughts, hints or explanations would be much appreciated.

Sincerely 

Tom
