Vlad Mihalcea High-performance Java Persistence Pdf [2021] File

High-Performance Java Persistence, authored by Vlad Mihalcea, stands as a definitive guide for developers seeking to bridge the gap between Java application logic and relational database efficiency. While many developers treat Java Persistence API (JPA) and Hibernate as "black boxes" that magically handle data, Mihalcea argues that true performance requires a deep understanding of the underlying database engine and the abstraction layer’s inner workings. The book is not merely a manual for Hibernate; it is an exhaustive exploration of JDBC, database internals, and the nuances of transaction management.

His book is the culmination of that experience. It is not a beginner’s introduction to JPA. It is a masterclass for the intermediate developer ready to become an expert. Connection pooling (HikariCP, connection lifecycle)

• Optimistic Locking: Using @Version to prevent lost updates without heavy database locks.
• Pessimistic Locking: The difference between PESSIMISTIC_READ, PESSIMISTIC_WRITE, and the dreaded PESSIMISTIC_FORCE_INCREMENT.
• Non-repeatable reads and phantom reads: How to map isolation levels (Read Committed, Repeatable Read, Serializable) to JPA LockModeType.
