Introduction
N+1 queries are a prevalent performance issue in software applications that involve retrieving data from databases. The N+1 query problem occurs when an application retrieves a collection of records and their associated data by making a separate query for each record, resulting in N+1 database queries (1 query to fetch the collection and N queries to fetch the associated data for each record). This inefficient querying pattern can significantly slow down applications and put unnecessary load on the database. In this comprehensive blog post, we will explore various techniques to avoid N+1 queries in Python, including best practices and
