Understanding the persistence context as a transactional buffer. You will learn how to write code that

The choice of primary key generation impacts write throughput. Strategies like GenerationType.IDENTITY disable Hibernate's ability to use JDBC batch inserts because the database must execute the insert immediately to determine the ID. Mihalcea advocates for GenerationType.SEQUENCE combined with optimized allocation sizes ( pooled or pooled-lo optimizers) to enable seamless write batching.

He has spent years solving performance issues for Fortune 500 companies. His blog, vladmihalcea.com , is consistently ranked as the top resource for Hibernate and JPA performance. When Vlad writes about the @SQLUpdate annotation or session-level batching, he writes from the perspective of someone who has profiled production systems running Terabytes of data.
