One developer wrote: “This book has served as a great reference for resolving multiple issues my current team has encountered while maintaining and upgrading a mature application codebase. It is simply the best persistent performance book that covers JDBC, Hibernate and JPA topics such as fetching, batching, flushing, relationships (must read chapter), transactions (that's a woow chapter!)”
What (Spring Boot 2.x, 3.x, Hibernate 5/6) are you running?
Standard Hibernate inspects every property of managed entities to see what changed. The book teaches advanced byte-code enhancement techniques to make dirty checking a zero-overhead operation. it’s a deep
A primary bottleneck in any enterprise application is connection acquisition. Establishing a physical database connection is an expensive cryptographic and network intensive operation.
The book covers a wide range of topics, from the basics of Java persistence to advanced techniques for optimizing performance. Here are some key takeaways:
A significant portion of the text is dedicated to demystifying Object-Relational Mapping (ORM) tools, specifically Hibernate. While ORMs are designed to boost developer productivity by automating SQL generation, they can inadvertently generate catastrophically inefficient queries if used incorrectly. 3. Advanced Performance Tuning The primary
Vlad Mihalcea’s High-Performance Java Persistence has become a modern classic for Java developers who want to master database access performance. This isn’t another beginner’s guide to JPA or Hibernate. Instead, it’s a deep, practical journey into the inner workings of JDBC, ORM frameworks, and databases themselves. The book is built on a single, crucial idea: to build a fast and scalable Java application, your persistence layer must resonate with your database system.
The most infamous performance antipattern in JPA is the N+1 query problem. The book dedicates significant real estate to this issue.
