Last modified:
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Hypersistence Optimizer is that tool!
Introduction
In this article, I’m going to show you 9 tips that will help you speed up your Oracle database application when using JPA and Hibernate.
To get the most out of the relational database in use, you need to make sure the data access layer resonates with the underlying database system, so, in this article, I’m going to present you several tips that can boost up the performance of your Oracle, JPA and Hibernate applications.

Introduction
Because performance tuning is very important when it comes to developing a data access layer, in this article, I’m going to show you how you can optimize the famous Hibernate Caveat Emptor application using Hypersistence Optimizer.
The Caveat Emptor application was created by Christian Bauer and Gavin King for the Hibernate in Action book they published in 2004 and was included in both the first and second editions of the well-known Java Persistence with Hibernate book.

Introduction
In this article, I’m going to explain why you should always use the Hibernate Dynamic Update feature for entities that map JSON properties.
Since Hibernate ORM does not offer support for JSON column types, we are going to use the Hibernate Types library, which provides a JsonType that allows you to map String, Map, List, JsonNode, Java Records, or POJOs on JSON columns, no matter if you are using PostgreSQL, MySQL, Oracle, SQL Server, or H2.

Introduction
In this article, we are going to see how SQL Server Foreign Key constraints are locking the parent record when executing a child record UPDATE.
This situation is specific to SQL Server and happens even when using the Read Committed Snapshot Isolation level.

Introduction
In this article, I’m going to explain how we can index JSON columns when using MySQL.
While other relational database systems provide GIN (Generalized Inverted Index) indexes, MySQL allows you to index a virtual column that mirrors the JSON path expression you are interested in indexing.
