YugabyteDB Connection Pooling
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 the overhead of acquiring a new connection when using YugabyteDB and why connection pooling is mandatory for performance.
From Hibernate Types to 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 explain why the Hibernate Types became Hypersistence Utils, and how you can migrate your old dependency to Hypersistence Utils 3.0.
Spring MDC Transaction Logging
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 to configure a Spring application to use MDC (Mapped Diagnostic Context) for transaction logging.
This technique is going to help us inject the Persistence Context information as well as the associated database transaction identifier in all the log entries emitted from within a @Transactional service method.
Spring Data Hibernate Entity Listeners
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 configure Spring Data to register several Hibernate Entity Listeners that can intercept entity state modifications.
As I explained in this article, JPA also offers an event listening mechanism that you can configure via the @EntityListeners, @PostPersist or @PostUpdate, or PostRemove annotations. However, the JPA solution is way too limited as it doesn’t allow you to interfere with the EntityManager directly.
Therefore, I prefer using the Hibernate Entity Listeners mechanism, which you can easily integrate with Spring Data, as this article demonstrates.
The best UUID type for a database Primary Key
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 UUID (Universally Unique Identifier) type works best for a database column that has a Primary Key constraint.
While the standard 128-bit random UUID is a very popular choice, you’ll see that this is a terrible fit for a database Primary Key column.
The best way to use UNION, INTERSECT, and EXCEPT with 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 write UNION, INTERSECT, and EXCEPT queries with Hibernate.
While you could have always used all these relational set operations using native SQL queries, starting with Hibernate 6, you can use UNION, INTERSECT, and EXCEPT in JPQL and Criteria entity queries.
This is all possible because of the new Semantic Query Model that Hibernate has introduced in version 6.
The best way to do the Spring 6 migration
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 you can get the most out of the Spring 6 and Hibernate 6 migration.
The tips in this article are based on the work I’ve done to add support for Spring 6 in Hypersistence Optimizer and the High-Performance Java Persistence project.
The Spring Data JPA findById Anti-Pattern
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 Spring Data JPA findById method can become an Anti-Pattern when using it to reference parent entity associations.
