This month Wes St. Clair will be talking about caching in Django.
It seems inevitable that if you grow a large, configurable Django app, you will end up in a place where you are hitting the database far more than you would like, and improving performance will require a large refactor and a loss of code maintainability. Sometimes, caching query results is the best solution. We will talk about caching strategies in general, and Django Cachops, an elegant and powerful ORM caching app.
IMT will happily provide Pizza and Soda.
Hope to see you there!
