[rrd-users] Using RRD to calculate recently popular users

We are trying to see if RRDTool is a good fit to build a popularity service
for a social network.
The requirements are:
A unique score is given to every user based on various factors. The number
of such users could run into millions. We then feed this score along with
the userids to a datastore. We should then be able to query the store for
answers to questions like:
* Who are the top 5 active users in the network?
* Who are the top 5 active users in the last one month and how has their
activity changed in the last week?
The reasons why we choose RRD:
1. The data is time based.
2. We need some RR database since we intend to discard old data in a RR
I read that RRDTool allows only numeric data to be captured. But we need
some book-keeping data too that needs to be stored and retrieved later.
Is it possible to build such a service using RRDTool?
Any help is greatly appreciated.
