Why Do ORMs Sometimes Over-fetch Unnecessary Data? Are you curious about why ORMs sometimes fetch more data than necessary? In this video, we’ll explain how object-relational mappers work and why over-fetching happens. We’ll start by discussing the basic role of ORMs in simplifying database interactions and how they manage data retrieval. You’ll learn about common techniques like eager loading and lazy loading, and how these strategies can lead to retrieving extra data or multiple database queries, which can slow down your application. We’ll also cover the concept of the N plus one problem, a common challenge when working with related data in ORMs. Additionally, we’ll share practical tips on how to customize your queries, select only the fields you need, and choose the right fetch strategy to optimize performance. Monitoring your database queries is another key step, and we’ll show you how profiling tools can help identify unnecessary data transfers. Sometimes, writing raw SQL queries for specific parts of your application can give you more control and better efficiency. Understanding these concepts helps you balance the convenience of ORMs with the need for optimized data handling, keeping your app fast and responsive.
