The best way to use JOIN FETCH and Pagination with Spring
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Introduction
In this article, we are going to see how we can use the JOIN FETCH clause when fetching a child collection eagerly while also limiting the number of parent records using pagination in a Spring Data JPA application.
I decided to write this article because the most common solution used in many projects turns out to be extremely inefficient.
The best way to use Spring Data query methods

Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.

Introduction
In this article, we are going to see how Spring Data query methods are built, when you should use them, and especially when you should avoid them.
I decided to write this article after answering this StackOverflow question, which depicts an 87-character-long Spring Data query method.
TL;DR, Don’t write query methods that cannot even fit on the screen.
The best way to use SQL NOWAIT
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.

Introduction
In this article, we are going to see what is the best way to use the amazing SQL NOWAIT feature that allows us to avoid blocking when acquiring a row-level lock.
Since all the top major database support this functionality, Hibernate offers a NOWAIT option that allows you to render the proper database-specific syntax associated with this feature without risking database portability.
YugabyteDB Architecture
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Introduction
In this article, we are going to explore the YugabyteDB architecture and see how it manages to provide automatic sharding and failover without compromising data integrity.
YugabyteDB is a distributed SQL database, so its architecture is different than the ones employed by traditional relational database systems.
The best way to generate a TSID entity identifier with JPA and Hibernate

Introduction
In this article, I will show you the best way to generate a TSID entity identifier with JPA and Hibernate.
Prior to continuing, if you are not familiar with the advantages of using compact Time-Sorted Identifiers, like TSID, check out this article first.
Fault Tolerance with Spring Data and YugabyteDB
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Introduction
In this article, we are going to see how we can achieve fault tolerance in your Spring Data application with the help of YugabyteDB.
As previously explained, YugabyteDB is an open-source distributed SQL database that combines the benefits of traditional relational databases with the advantages of globally-distributed auto-sharded database systems.
Scaling a Spring application with a YugabyteDB cluster
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Introduction
In this article, we are going to see that scaling the data access layer of a Spring application can be done very easily with a YugabyteDB cluster.
As I explained in this article, YugabyteDB is an open-source distributed SQL database that offers all the benefits of a typical relational database (e.g., SQL, strong consistency, ACID transactions) with the advantages of a globally-distributed auto-sharded database system (e.g., NoSQL document databases).
The awesome BaseJpaRepository from Hypersistence Utils
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Introduction
In this article, I’m going to explain how you can use the BaseJpaRepository from the Hypersistence Utils OSS project as an alternative to the default Spring Data JpaRepository.
The reason why I’m not using the default JpaRepository on any of my Spring projects is that it provides some terrible defaults that can be very easily misused, like:
So, there are two ways you can fix the problems induced by the default JpaRepository:
- You can use the
HibernateRepositoryto deprecate the questionable methods that you shouldn’t have inherited in every single JPARepository. - You can use a different
BaseJpaRepository, as I explained in this article.
While you could create your own BaseJpaRepository, as I did for this article, it’s much easier to get it from a battle-tested OSS project that you might have already added to your dependency list.
And since Hypersistence Utils already provides the BaseJpaRepository abstraction and its implementation, this article is going to show you how to use it.
