Embrace Events and let CRUD die
The document discusses the concept of event sourcing in software development, emphasizing the importance of treating changes as first-class citizens and capturing domain events effectively. It contrasts traditional CRUD approaches with denormalization and read models for better performance, particularly in read-heavy applications. The author also highlights the significance of testing, including behavior-based testing, and the need for effective workshops like event storming to facilitate understanding and modeling of complex systems.
