Without the LazyToOneOption.NO_PROXY annotation, the parent-side of a @OneToOne association is always going to be fetched eagerly even if you set it to FetchType.LAZY and enabled bytecode enhancement lazy loading.
Mapping Java Records to JSON columns using Hibernate
Introduction In this article, I’m going to explain how we can map Java Records to JSON columns when using Hibernate.

Introduction In this article, I’m going to explain how the JPA and Hibernate first-level mechanism works and how it can improve the performance of your data access layer. In JPA terminology, the first-level cache is called Persistence Context, and it’s represented by the EntityManager interface. In Hibernate, the first-level cache is represented by the Session interface, which extends the JPA EntityManager one.
