While Amazon primarily sells the paperback and Kindle versions, the Kindle version provides a similar digital experience.
A specialized developer tool he created that automatically scans your Java project to detect Hibernate configuration errors and performance anti-patterns. It explains how to effectively use batching to
The book is divided into four parts:
Default Hibernate behavior executes SQL statements sequentially, forcing a network round-trip for every insert, update, or delete operation. This behavior destroys throughput during bulk operations. Configuring Automated Batching
Ordering inserts and updates allows Hibernate to group identical SQL statements together, maximizing the efficiency of a single JDBC batch execution block. Transaction Demarcation
While "free PDF" links may appear in search results, these are often outdated, incomplete, or bundled with malware. Supporting the author directly ensures you get the most current version, including updates for the latest Hibernate and Spring Boot releases. 💡 Summary for Senior Engineers
