MEM002warningPro

unbounded-eager-load

Eager loading pulls all related records without a limit.

Applies to: JavaScript, Python, TypeScript

Why this matters

Loading all related records (e.g., include: { contacts: true }) pulls the entire relation into memory. A user with 50,000 contacts will load all of them in one query. Use pagination (take:) or select specific fields instead.
