Hi,

iam looking for performant way to do the following:

User login
Fetch all Friends from Twitter
Fetch all Followers from Twitter
Display all Friends wich aren't Followers

The Problem: How to do this in a performant way? An user can have up to 2 Million Friends or Followers. In the moment im Storing both inside an sqllite table an compare them through an loop. When the user comes back the table is cleared and process starts again.

This works finde on 100 - 1000 Friends.. but will be tricky with 500000 Friends. I cant cache the lists because they can change every moment..

Does someone knows a good way to handle such big amount of data?
