Common pitfalls of Event Sourcing and how to address them

Plenty of great content has been written about the problems Event Sourcing can help you solve. But after almost 10 years of using Event Sourcing in a distributed occasionally connected environment, I've experienced a lot of real-world challenges. In this talk, I'm going to talk about common challenges I've run into and the options I use to address them. I'll cover aggregate boundary challenges, problems finding the invariants, cross-domain communication, value types and events, versioning of events, eventual consistency of projections, projection bugs, time to rebuild projections, supporting blue/green deployments and more.
