Let’s be brutally honest. Without the Transactional Outbox Pattern, your event-driven system is nothing more than a digital con artist. It’ll gladly take your customer’s money, and the moment it crashes, it ghosts them completely. You’re not building a reliable service; you’re building an automated rip-off machine. That might sound harsh, but the underlying risk…
What if I told you the Spring Event logic you just wrote, the code you believe is clean and decoupled, is actually a poison slowly sickening your entire system? This is the harsh reality of the limits of Spring Events when applied outside of a monolith. Inside a single application, Spring Events are a vitamin….
That “simple” change that just broke three unrelated modules? That isn’t a bug—it’s a symptom of a disease called tight coupling. And every time you make a direct service call, you’re making the disease worse. Your codebase becomes a tangled web of dependencies, making every future change a nightmare of unpredictable side effects. Most developers…
Most developers see @Transactional as a magic spell for data integrity. But a deeper understanding reveals it’s a powerful policy enforced by a proxy. This perspective immediately leads to a critical design question that is often overlooked: where should this policy be declared? This is not a simple coding convention. This decision directly impacts your…
We’ve all seen it. A critical operation fails halfway through, leaving data in a corrupted, inconsistent state. The @Transactional annotation was supposed to be the safety net, but it failed. The problem isn’t the tool. It’s the blind faith we place in it. To build truly resilient systems, we can’t just trust the magic. We…
