Oskar Dudycz - Event-driven Modelling Anti-Patterns - EventCentric 2025

EventCentric 2025 - Organised by Aardling (https://aardling.eu/) https://eventcentric.eu   / eventcentric-eu   Have you heard about Passive Aggressive Events or CRUD sourcing? Or maybe about the Clickbait event? If you don't, check this talk, as knowing only best practices is one side of the coin. Knowing what NOT to do can be even more important. During the session, you'll learn the specifics of event-driven modelling, starting with worse practices and knowing why and how to avoid them. You'll hear the story of Rakso, who ended up with the distributed monolith and understand how ignoring modelling practices led him to that pitiful place. Thanks to that, you'll see what and how to avoid it in your case. You'll also find out that there's a thin line between bad and good practices: context.
