While the official Hibernate documentation tells you what a feature does, High-Performance Java Persistence tells you when and why to use it—and more importantly, when to avoid it.

Using Set vs. List for collections changes how Hibernate removes orphaned entities.
In the world of enterprise Java development, there is a pervasive myth that Java applications are inherently slow. While the JVM has evolved into a high-performance powerhouse, the bottleneck in most enterprise applications rarely lies in the business logic or the JVM itself. Instead, it almost always resides in the data access layer. Note: This article is a review and guide
Many performance issues in enterprise applications stem from a mismatch between object-oriented programming and relational database design. Vlad Mihalcea, a Java Champion and Hibernate expert, bridges this gap by explaining how to align your application logic with the underlying database's strengths. The book is structured into three distinct parts: High-Performance Java Persistence - Vlad Mihalcea
The book answers these by establishing a set of rules that govern data access performance. serves as a critical bridge between the world
To prove the value of the book, let's look at three micro-lessons you won't find in basic tutorials:
Many developers treat the database as a "magic box." They assume that calling save() or iterating over a list will result in optimal SQL execution. When the application slows down, the instinct is often to blame the garbage collector or add more hardware. Vlad Mihalcea argues, and proves, that the issue is usually a lack of understanding regarding how the ORM generates SQL.
This is the meat of the book. Mihalcea has a reputation for finding edge cases that cause LazyInitializationException or N+1 query problems.
