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. Because Hibernate ORM does not offer built-in support for JSON, we are going to use the Hiberate Types library, which allows you to map entity attributes to JSON column types, no matter if you are using Oracle, SQL Server, PostgreSQL, or MySQL.
The JPA and Hibernate first-level cache
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.

Introduction In this article, I’m going to explain how the Hibernate Session doWork and doReturningWork methods work, and when you should use them.
Spring Boot performance monitoring
Introduction To ensure that your Spring Boot application fulfills the SLA (Service Level Agreement) requirements, you need a performance monitoring tool. In this article, I’m going to show you how you can monitor the data access layer of a Spring Boot application using Hypersistence Optimizer.
