Introduction When I started writing High-Performance Java Persistence, I realized I needed a GitHub repository to host all the test cases I needed for the code snippets in my book, and that’s how the high-performance-java-persistence GitHub repository was born. The high-performance-java-persistence GitHub repository is a collection of integration tests and utilities so that you can test JDBC, JPA, Hibernate and jOOQ features with the utmost ease.
Introduction I’m happy to announce you that FlexyPool 2 has just been released! I started FlexyPool in 2014 because, at the time, I was working as a software architect on a large real-estate platform and we were about to launch the system into production. Because the system was split into multiple modules, we needed a way to figure out the right pool size for each module. To make matters worse, the front-end nodes could be auto-scaled, so we needed monitoring and same fallback mechanisms in case our initial assumptions did not hold… Read More
Introduction As previously explained, although Hibernate does not support database ARRAY column types by default, you can easily implement a custom Hibernate ArrayType. While the previous solution worked on PostgreSQL, in this article, you are going to see that it is fairly easy to adapt it to HSQLDB.

Because one of our community members asked me on the Hibernate forum about this topic, I decided it is a good opportunity to write about this lesser-known JPA Criteria API feature.

Most web designers I knew were very familiar with WordPress, not to mention that it powers 25% of all Internet websites. Four years, I’ve been using the Free Plan which, other than a Domain Name, does not cost… Read More
