"High-Performance Java Persistence" by Vlad Mihalcea is a comprehensive guide focusing on optimizing Java data access through in-depth coverage of JDBC, JPA, and Hibernate performance tuning. The book emphasizes practical techniques, including JDBC batching, DTO projections, and advanced caching, designed to resolve N+1 query issues and reduce database contention. You can find the book, including the PDF version, on the official Vlad Mihalcea website.
"High-Performance Java Persistence" by Vlad Mihalcea provides comprehensive, in-depth techniques for optimizing data access layers in Java applications using JDBC, Hibernate, and jOOQ. The book, frequently updated on Leanpub, covers critical areas including connection pooling, statement batching, and advanced database concurrency control.

Add these properties to your application.properties (Spring Boot): Official Book Information
spring.jpa.properties.hibernate.jdbc.batch_size=50
spring.jpa.properties.hibernate.order_inserts=true
spring.jpa.properties.hibernate.order_updates=true
spring.jpa.properties.hibernate.jdbc.batch_versioned_data=true
Mihalcea explains why order_inserts matters (grouping same-table inserts together).
@ManyToOne vs. @OneToManyMost developers map associations without considering the database cost. Vlad argues that @ManyToOne associations are almost always preferable to @OneToMany for performance. He details the "mapping" chapter with analysis of how Hibernate translates your Java code to SQL, including the performance hit of using Set vs. List collections.
Modern applications cannot rely on SELECT FOR UPDATE for everything. Mihalcea introduces:

Batch insert:

entityManager.persist(entity);
if (i % 20 == 0)
entityManager.flush();
entityManager.clear();

SELECT * FROM post WHERE id > :lastId ORDER BY id LIMIT 50
