The best way to write a Spring Data Exists Query
Last modified:
Are you struggling with performance issues in your Spring, Jakarta EE, or Java EE application?
Imagine having a tool that could automatically detect performance issues in your JPA and Hibernate data access layer long before pushing a problematic change into production!
With the widespread adoption of AI agents generating code in a heartbeat, having such a tool that can watch your back and prevent performance issues during development, long before they affect production systems, can save your company a lot of money and make you a hero!
Hypersistence Optimizer is that tool, and it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, Micronaut, or Play Framework.
So, rather than allowing performance issues to annoy your customers, you are better off preventing those issues using Hypersistence Optimizer and enjoying spending your time on the things that you love!
Introduction
In this article, I’m going to show you the best way to write a Spring Data Exists Query that’s efficient from an SQL perspective.
While doing consulting, I’ve encountered several options that are commonly used without developers knowing there are actually better alternatives.

Introduction
In this article, we are going to see what Serializability means and what guarantees does it offer.
Relational database systems provide a Serializable isolation level that’s supposed to provide transaction Serializability. However, as you will soon see, some databases even provide Strict Serializability, which is a combination of Serializability and Linearizability.

In this article, I’m going to show you the best way to configure the Spring Boot Application Properties file.
This is not just theoretical advice. I applied all these tips when developing RevoGain, a web application that allows you to calculate the gains you realized while trading stocks, commodities, or crypto using Revolut.

Introduction
In this article, I’m going to show you how to write EXISTS subqueries with JPA and Hibernate.
EXISTS subqueries are very useful as they allow you to implement SemiJoins. Unfortunately, many application developers are not aware of SemiJoins, and they end up emulating it using EquiJoins (e.g., INNER JOIN) at the cost of query performance.

Introduction
In this article, I’m going to show you how you can use the Keyset Pagination technique with Spring or Spring Boot.
While the default offset-based pagination provided by Spring Data PagingAndSortingRepository is useful in many situations, if you have a large result set that you have to iterate over, then the Keyset Pagination or Seek Method technique provides better performance.
