SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Large, unfiltered database selects in Laravel increase memory usage and slow down API responses by transferring and hydrating more data than you actually need.

Core Features & Use Cases

  • Select only required columns in base queries to reduce payload size and improve performance.
  • Apply column selection to eager-loaded relations to avoid unnecessary data transfer and keep N+1 issues under control.
  • Keep DTOs/resources aligned with the selected fields so you don’t accidentally rely on attributes you didn’t fetch.

Example: In an endpoint that returns paginated users and includes each user’s author details for related posts, selecting only id, name, and the specific post fields prevents returning unused columns while still supporting with() eager loading.

How do I select only specific columns in Laravel Eloquent to reduce memory usage?▼

Select specific columns in Laravel Eloquent by applying the `select()` method to your base queries and relation constraints, which reduces payload size and application memory pressure by avoiding `*`.

Why does my Laravel API use so much memory when returning paginated Eloquent models?▼

Laravel API memory usage spikes when returning paginated Eloquent models because unfiltered database selects transfer and hydrate more data than needed, increasing memory pressure and slowing responses.

How do I apply column selection to eager-loaded relations in Laravel?▼

Apply column selection to eager-loaded relations in Laravel by adding `select()` constraints inside your `with()` calls to avoid unnecessary data transfer and keep N+1 issues under control.

What is the best way to optimize Laravel Eloquent queries for large payloads?▼

The best way to optimize Laravel Eloquent queries for large payloads is selecting only required fields on base models and eager-loaded relations, ensuring returned DTOs or resources match the fetched data.

Can I use select columns with Laravel eager loading without breaking my DTOs?▼

Yes, you can use `select()` with Laravel eager loading without breaking DTOs by keeping your resources aligned with the selected fields, ensuring you do not rely on unfetched attributes.

When should I not use selective column fetching in Laravel Eloquent?▼

Avoid selective column fetching in Laravel Eloquent when your DTOs or resources require attributes you did not include in the `select()` statement, as accessing unfetched columns will cause errors.
