## The N+1 Problem Explained
Say you query for a list of movies, and each movie includes some data about the director of the movie.
Also assume that the Movie and Director entities are owned by two different services.
In a naïve implementation, to load 50 movies, you would have to call the Director service 50 times: once for each movie.
In a naïve implementation, to load 50 directors, you would have to call the Director service 50 times: once for each movie.
This totals 51 queries: one query to get the list of movies, and 50 queries to get the director data for each movie.
This obviously wouldn’t perform very well.
