        FetchType is an enumeration in the Java Persistence API (JPA) that is used to define the fetching strategy for associations (relationships) between entities in a relational database.

        There are two main values for FetchType:

        • FetchType.EAGER: the association is loaded immediately when the owning entity is loaded.
        • FetchType.LAZY: the association is not loaded unless it is explicitly accessed.

        This rule raises an issue when the fetch argument is explicitly set to FetchType.EAGER.

        Why is this an issue?

        How can I fix it?

        More Info

        Using FetchType.EAGER can lead to inefficient data loading and potential performance issues. Eager Loading initializes associated data on the spot, potentially fetching more data than needed.
