Ten years of blogging
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!
Ten years later!
Ten years ago today, I decided to start blogging and published this article about injecting a List of Spring beans using the @Autowired annotation.
How to find the source of an SQL query generated by Hibernate
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 find the source of an SQL query generated by Hibernate.
Knowing where a given SQL query originates from is very useful when trying to investigate performance issues caused by either long-running queries or queries that are executed excessively (e.g., N+1 query issues).
How to fetch multiple JPA collections with Blaze Persistence MULTISET
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 fetch multiple JPA entity collections without generating an implicit Cartesian Product with the MULTISET strategy offered by the Blaze Persistence open-source project.
The MULTISET fetch strategy is inspired by the MULTISET operator offered by jOOQ.
If you are not familiar with the MULTISET operator, then check out this article first, in which I explain why this jOOQ feature is truly revolutionary.
PostgreSQL JDBC Statement Caching
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’re going to see how the PostgreSQL JDBC Driver implements Statement Caching and what settings we need to configure in order to optimize the performance of our data access layer.
The best way to hide the JPA entity identifier
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 show you the best way to hide the JPA entity identifier so that the users of your application won’t be able to guess and access data that belongs to other users.
This has been a recurring question that I’ve been getting when running training or workshops, so I decided it’s a good idea to formalize it in an article.
The best way to use JPA bidirectional sync methods
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 what are the best way to use JPA bidirectional sync methods for one-to-many, one-to-one, and many-to-many associations.
For an introduction to why you need sync methods for your bidirectional JPA associations, check out this article first.

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 the SQL Server useBulkCopyForBatchInsert configuration property works when using JDBC, JPA, or Hibernate.
JDBC Profiling with VisualVM
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 do JDBC profiling using the VisualVM tool to find slow-running SQL queries or discover N+1 query issues.
