It's recommended to set all entity relationships like @ManyToOne, @OneToMany. to use lazy loading by default to enhance performance.When you need to load related entities eagerly for particular cases, you can override lazy loading either by using @EntityGraph or JOIN FETCH in your queries. Both approaches help prevent the N+1 query issue. Among these, @EntityGraph is often favored because it keeps fetching strategies separate from the query definitions, making the code cleaner and easier to maintain.
