: For bulk operations (e.g., inserting thousands of records), executing individual statements is inefficient. The book dedicates significant space to batch updates , showing how to configure JDBC and Hibernate to group many operations into a single database round-trip, drastically reducing latency and improving throughput. Consider it your compass for navigating the complex
Creating a physical database connection is an expensive cryptographic and network operation. Applications must use a high-performance connection pool like .
