In JPA (Java Persistence API) and Hibernate applications, queries can sometimes take a long time to execute, especially when working with large data sets. To avoid long-running queries, it’s important to set a query timeout, which limits the maximum amount of time that a query is allowed to run before it times out. In this tutorial, we will learn how to set a query timeout for JPA/Hibernate applications.
The Java Persistence API (JPA) is a lightweight, POJO-based framework for Java persistence.
By using a standard persistence API, you can fetch, persist and manage data between Java objects and a Relational Database.
WildFly application server uses Hibernate ORM as JPA Provider. Within this section, you will find tutorials both for Hibernate standalone applications and for Jakarta Persistence API.

Jakarta Persistence API (JPA) is a Java specification for accessing, persisting, and managing data between Java objects/classes and a relational database. It is a part of the Jakarta EE platform, and it provides a standard approach for ORM (Object-Relational Mapping). In this JPA tutorial, we will learn how to use JPA to create, read, update, and delete (CRUD) data in a database.
