For bulk inserts and updates, individual JDBC calls are inefficient. Mihalcea demonstrates how to configure Hibernate batching ( hibernate.jdbc.batch_size ) to reduce network latency and improve throughput dramatically. 4. Caching Mechanisms When to Use DTO Projections Mihalcea excels at
If you are using Spring Boot 3+, which requires Hibernate 6, this PDF remains the definitive guide.
