Can tooling make event sourcing implementations easier? Carl and Richard talk to Einar Ingebrigsten about his work on cratis.io - a set of open-source tools for implementing event sourcing in your application. Einar discusses the foundational elements of event sourcing and the common implementation patterns he developed at Cratis. With extensive support for .NET, Cratis provides tooling for data storage, event response, replay management, and much more. Also in development is Cratis Studio for collaborating visually on an event model - and generating the code in the process.
