Flagpole Sitta is a gem that main purpose is to make it easier to effectively fragment cache in dynamic fashions in Rails. When ever a cache is created it is associated with any model and/or record you tell it to be from the view helper method. When that model and/or record is updated all it's associated caches are cleared. Flagpole also expects you to put all your database calls into Procs/Lamdbas. This makes it so that your database calls wont have to happen unless your cache hasn't been created. Thus speeding up response time and reducing database traffic.
