In the realm of modern software development, managing and maintaining data integrity is paramount. Traditional approaches often involve updating the state of an application directly within a database. However, as systems grow in complexity, ensuring data consistency and traceability becomes more challenging. This is where Event Sourcing, coupled with a powerful distributed streaming platform like, emerges as a robust solution and a great data structure to work with.

What Is Event Sourcing?

At its core, Event Sourcing is a design pattern that captures every change or event that occurs in a system as an immutable and sequentially ordered log of events. Instead of persisting the current state of an entity, Event Sourcing stores a sequence of state-changing events. These events serve as a single source of truth for the system’s state at any given point in time.
