Vlad Mihalcea High-performance Java Persistence Pdf -

How to reduce network round-trips by grouping SQL statements.

A significant portion of the book is dedicated to Hibernate, the most popular JPA implementation. Mihalcea moves beyond basic CRUD operations to tackle complex issues such as flushing strategies, second-level caching, and the often-misunderstood "N+1 query problem." He provides clear, evidence-based recommendations on mapping types, emphasizing that developers should prefer simple, efficient mappings over complex inheritance structures that can degrade performance. His analysis of entity state transitions and the persistence context helps developers avoid common pitfalls where the framework might perform unnecessary database round-trips. vlad mihalcea high-performance java persistence pdf
