In the vast landscape of software architecture, managing application state is a foundational challenge. Traditionally, applications store their current state in databases, overwriting previous values as changes occur. While seemingly straightforward, this approach often discards valuable historical information, making auditing, debugging, and understanding past system behavior difficult. Enter Event Sourcing, a powerful architectural pattern that fundamentally shifts how application state is managed. Instead of merely storing the latest state, Event Sourcing captures every change to that state as an immutable sequence of events, providing a complete, auditable history of everything that has ever happened within the system.
