Imagine having a tool that can automatically detect if you are using Java Persistence and Hibernate properly.
No more performance issues, no more silly mistakes that can cost you a lot of time and money.
Now, you have this tool. It's called Hypersistence Optimizer.
Vlad Mihalcea is a Java Champion and one of the top Hibernate ORM project committers. He created the Hypersistence Optimizer tool which scans your application configuration and mappings and tells you what changes you need to do to speed up your data access layer.
He's been answering thousands of questions about Hibernate and JPA on StackOverflow for which he's got gold badges for Hibernate, Java, and JPA tags.
Whenever he finds something interesting, he likes to share it on his personal blog. He believes in Open Source Software, and he thinks every developer should get involved, one way or the other.
