Stop Joining Tables In Your “Modular” Monolith

Modular monoliths are all the rage, but is yours actually just a "Big Ball of Mud" with a clean coat of paint? In this video, I break down the hidden trap of joining tables across module boundaries and why database-level coupling is just as dangerous as tight coupling in your code. We’ll explore the "Simple Join" trap, why internal APIs provide better evolvability, and a real-world example to show how aligning with business functions can eliminate the need for cross-boundary queries entirely. 🔗 Kurrent https://kurrent.io 🔔 Subscribe:    / @codeopinion   💥 Join this channel to get access to a private Discord Server and any source code in my videos. 🔥 Join via Patreon   / codeopinion   ✔️ Join via YouTube    / @codeopinion   📝 Blog: https://codeopinion.com 👋 Twitter:   / codeopinion   ✨ LinkedIn:   / dcomartin   📧 Weekly Updates: https://mailchi.mp/63c7a0b3ff38/codeo... 00:00 - The Illusion of the Modular Monolith 00:43 - The "Simple" Join: A Hidden Coupling Trap 02:09 - Why Database-Level Coupling is Dangerous 03:01 - Solving Coupling with Internal APIs 04:19 - Requirements vs. Reality: Available to Promise (ATP) 06:38 - Architectural Trade-offs & Evolvability 08:36 - Final Thoughts: Is your Monolith a "Big Ball of Mud"?
