For Java developers, this is the realm of JDBC, Hibernate, EclipseLink, and JPA (Jakarta Persistence). However, achieving high performance in this space is notoriously difficult. Misconfigurations, lazy loading pitfalls, and SQL anti-patterns can kill throughput faster than any bottleneck in your business logic. Entities are managed
