Introduction In this article, we are going to see what is the best way to map the entity version property with JPA and Hibernate. Most often, we overlook the basic entity type mappings, focusing more on associations or querying options. However, basic types can also have a significant impact on application performance, especially if the type in question is used in many entity mappings.
Introduction In this article, we are going to see how optimistic locking version property works when using JPA and Hibernate. Most often, we overlook basic concepts and focus only on more advanced topics such as associations or queries, without realizing that basic mappings can also have a significant impact when it comes to persistence effectiveness and efficiency.
Introduction In this article, I’m going to show you how the JPA @Version entity property works when using Hibernate. The most significant benefit of adding a version property to a JPA entity is that we can prevent the lost update anomaly, therefore ensuring that data integrity is not compromised.
How to increment the parent entity version whenever a child entity gets modified with JPA and Hibernate
Introduction StackOverflow and the Hibernate forum are gold mines. Yesterday, I bumped on the following question on our forum: Usually, the rationale behind clustering objects together is to form a transactional boundary inside which business invariants are protected. I’ve noticed that with the OPTIMISTIC locking mode changes to a child entity will not cause a version increment on the root. This behavior makes it quite useless to cluster objects together in the first place. Is there a way to configure Hibernate so that any changes to an object cluster will cause the… Read More
Introduction In my previous post, I introduced the OPTIMISTIC_FORCE_INCREMENT Lock Mode and we applied it for propagating a child entity version change to a locked parent entity. In this post, I am going to reveal the PESSIMISTIC_FORCE_INCREMENT Lock Mode and compare it with its optimistic counterpart.
