Keep your streams short! Or how to model event-sourced systems efficiently

In event-sourced systems, no data is lost. We record new facts after each business operation. That's a huge benefit but also a challenge. At some point, we realise that we have too many events in our streams. That causes a whole variety of issues: operational, performance, versioning, but also cognitive load and blurring the entire picture. In this talk, you'll learn how to deal with the temporal aspect of our system and why it's essential to keep your streams short. You'll learn strategies and techniques to model your domain into streams efficiently. Thanks to that, you'll learn to efficiently create and maintain your event-sourced system, avoiding common pitfalls.
