Hibernate: Myths & Over-Engineering. ORMs vs SQL vs Hexagonal — Gavin King | The Marco Show

Gavin King (creator of Hibernate; now at IBM, formerly Red Hat/JBoss) joins Marco to slice through decades of ORM dogma. From “repositories per entity” and lazy loading pain to stateless sessions, DRY as commandment #1, Jakarta Data, and why you should often just write a SQL query (or even better, a database view) for real-world legacy schemas. It’s pragmatic persistence for Java developers who ship. What you’ll learn: – When a single SQL (or a DB view) beats layers of repositories – The 3 inheritance mapping strategies (and why table-per-class hurts) – Why DRY is more than architecture astronautics; let design emerge via refactoring – Stateless Session vs stateful: fewer surprises, fewer “magical” bugs – How Jakarta Data 1.0/1.1 departs from Spring Data (and why that helps) – Handling legacy schemas, performance, and the truth about “leaky abstractions” – Sensible rules of thumb for SQL & round-trips – LazyInitializationException: friend, not foe (and how to avoid it) 🎁 Giveaway If you could add one exciting new feature to Hibernate (anything at all, even wild or AI-powered) what would it be?
