📄 Description

According to the repo:

nplusone is a library for detecting the n+1 queries problem in Python ORMs, including SQLAlchemy, Peewee, and the Django ORM.
Many object-relational mapping (ORM) libraries default to lazy loading for relationships. This pattern can be efficient when related rows are rarely accessed, but quickly becomes inefficient as relationships are accessed more frequently. In these cases, loading related rows eagerly using a JOIN can be vastly more performant. Unfortunately, understanding when to use lazy versus eager loading can be challenging: you might not notice the problem until your app has slowed to a crawl.

I myself used this tech so many times. It acts like a mid-level layer on the Django apps. It also uses a logging module in order to log every single moment during the process.
