Understanding Event Sourcing

In this episode, we dive into an exploration of Event Sourcing, an architectural pattern that fundamentally changes how we think about application state. Rather than directly storing the current state, Event Sourcing rebuilds it from a sequence of events. We'll explore the key concepts that make this pattern work, including the critical distinction between state and events, and how the event store serves as the application's source of truth. The episode examines how entities evolve through time in this model, demonstrating why temporal awareness is essential when implementing Event Sourcing. We'll also clear up common misconceptions, particularly how this approach differs from simply emitting events, and discuss important performance considerations, especially when combined with Command Query Responsibility Segregation (CQRS). This introduction lays the groundwork for future episodes where we'll delve into practical implementation and the compelling benefits of Event Sourcing.If you want to know more check the article.
