Before diving into the book itself, it is crucial to understand the pedigree of its author. is a Java Champion and one of the top Hibernate ORM project committers . In addition to authoring this book, he created Hypersistence Optimizer , a tool that scans your application configuration and mappings to automatically identify performance issues in your data access layer. His expertise is built on years of real-world experience and thousands of hours of low-level investigation into how Hibernate, JPA, and database drivers behave under load. He runs a wildly popular blog (active since 2013) where he shares deep dives into Java, JPA, Hibernate, Spring, SQL, and database systems like Oracle, SQL Server, PostgreSQL, and MySQL. In short, when Vlad Mihalcea writes a book about database performance, the Java community pays attention.
