Let’s discuss Laravel Eager Loading with this article. As part of our Laravel Support Services, Bobcares provides answers to all of your questions.

Laravel Eager Loading

Eager Loading allows retrieving of all the items or the most related items altogether. However, Lazy loading only allows the retrieval of an item at a time. In the case of Databases, consider a database with two tables: questions and options. All options are linked to questions via the question_id column, and each question has several answers. To display our questions in the view, we must retrieve them from the database. There are two options for this. Let’s look into each of them:

Method 1: We obtain the questions, begin to loop through them, and then proceed to the database to retrieve the corresponding options for each question. “That’s lazy loading”, which means we’re holding off on retrieving the options until we need them.

Method 1: We retrieve the questions and associated alternatives directly from the database. So that when we display the questions, we do not make extra trips to the database to fetch the options, but rather display the options that already exist on the questions. And this is “Eager loading”.

Laravel Eager Loading: Advantages & Disadvantages

Laravel Eager Loading: Advantages

1. We get all we require all at once.

2. There is no lag when consumers access data while using the system.

3. Fewer queries to run against the database

Laravel Eager Loading: Disadvantages

1. We may be receiving info that we do not require.

2. The initial query is slow, which may be problematic if we need to retrieve *a lot* of records at once.

3. It takes up more memory.
