Presentation: A Stitch In Time Saves Nine_ Solving the N+1 Problem Presentation [PDF]
When dealing with databases, developers frequently run into the N+1 problem, in which they populate domain objects via queries in loops. This causes terrible performance drags. The talk shows how to solve the N+1 problem in plain PHP as well as Postgres. It concludes with a way of automating the PHP side, and includes editorializing about the origins of the N+1 problem in the developer mindset.
