The Marco Show is a bi-weekly podcast about AI, coding, and developer tools — hosted by Marco Behler, Developer Advocate for Java at JetBrains. Before JetBrains, Marco ran a consultancy in Munich, working with clients like BMW, Wirecard, and KVB, and built software at BWSO (now tresmo). He’s also a Java and Spring trainer, conference speaker, and writer of guides, courses, and videos. Each episode brings real conversations with tech people who actually build things: opposing opinions, hot takes, and useful insights for developers who want to go deeper.

    Hibernate: Myths & Over-Engineering. ORMs vs SQL vs Hexagonal — Gavin King

    📺 Note: This episode contains screensharing and live coding examples that work best visually. If you’d like to follow along, check out the full video version on YouTube: https://youtu.be/Qvh3VFlvJnE. Gavin King (creator of Hibernate) joins Marco to cut through the myths of Java persistence. When should you skip layers of repositories and just write SQL, or even model database views? What actually causes lazy-loading pain, and how do stateless sessions help? We cover Hibernate, JPA, and where Jakarta Data is headed, plus pragmatic advice for legacy schemas, performance, and keeping your code DRY. 💡 Topics in this episode: • SQL vs repositories (and why views can be your adapter layer) • The three inheritance strategies, and the trap of table-per-class • Stateless sessions vs stateful persistence contexts • LazyInitializationException explained (and avoided) • DRY first: let architecture emerge via refactoring • Jakarta Data 1.0/1.1: annotation processing, stateful repos, dynamic queries • Performance rule-of-thumb: minimize round-trips ⏱️ Timestamps (00:00) Teaser (01:00) Gavin King intro and early Hibernate motivation (03:59) Old-school open-source culture and discovery (08:39) SQL isn’t hard: minimize DB round-trips (10:03) “Leaky abstractions are good” (and why) (12:04) Architecture should emerge from code (15:44) DRY as commandment #1 (22:05) Reviewing a typical Spring Data setup (and pitfalls) (25:39) Inheritance strategies: joined vs single table vs table-per-class (30:06) One screen?
