In the last weeks I did some work on optimizing queries for the "Manage Supporter"-Interface in campaignion (online campaigning / online fundraising distribution). The goal is to filter Redhen contacts and then apply bulk-operations on them. In our larger databases we have up to 500,000 contacts and millions of activities - and the queries are not that simple either. How do you get “All supporters that signed at least two petitions last year but never made a donation”?
