The N+1 Problem in EF Core and how to overcome it
The N+1 problem is a common performance issue in ORMs (Object-Relational Mappers) like Entity Framework Core, where an initial query retrieves the parent objects, followed by N additional queries to retrieve the related child objects. This can lead to significant performance degradation, especially when dealing with large datasets.
In this article, we'll explore the N+1 problem in detail (and its solutions like eager loading, explicit loading, and lazy loading) and best practices for optimizing data access in EF Core applications.
