+== FetchType.LAZY
+
+In Spring JPA, lazy loading is achieved by annotating a field or property with ``FetchType.LAZY``.
+This approach leverages JPA's built-in mechanisms to defer the retrieval of the related entity until it is accessed.
+
+In contrast, {product-name} takes a different approach.
+Instead of using annotations, you wrap the object intended to be loaded lazily in a ``Lazy``-wrapper.
+This wrapper encapsulates the object and ensures it is only loaded when needed.

+public class Owner extends Person
+{
+	private final List<Lazy<Pet>> pets = new ArrayList<>();
+	//...
+----
+
+The ``Lazy``-wrapper makes lazy loading **explicit and flexible**, avoiding JPA-specific overhead and potential exceptions.
+But it introduces a custom, less-standardized approach that may increase boilerplate and requires developers to remember to use the wrapper, which could lead to errors if overlooked.

 == Repositories
 
 Entities in a repository are by default **not lazy**.
