Hi, 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? etc. 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 fashion. 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. Thanks, -- Gautham Pai, Software Engineer, weRead Website: http://buzypi.in/ Blog: http://blog.buzypi.in/ weRead: http://weread.com/ "What's life without an impossible dream"
