Introduction One of my major goals for Hibernate is to make sure we offer all sorts of performance improvements to reduce transaction response time and increase throughput. In Hibernate 5.2.10, we addressed the HHH-11542 Jira issue which allows you now to delay the database connection acquisition for resource-local transactions as well. In this article, I’m going to explain how Hibernate acquires connections and why you want it to delay this process as long as possible.
