Event Sourcing with Kafka
Implement event sourcing architectures using Kafka to build resilient and auditable systems.
What is Event Sourcing?
Event Sourcing is an architectural pattern where all changes to application state are stored as a sequence of immutable events.
Instead of just storing the current state of an entity, you store every single action that led to that state. Think of it like a ledger in accounting.
This means your database doesn't just hold the 'current version' of data, but a complete, ordered history of every change.
Why Use Event Sourcing?
Event Sourcing offers several compelling benefits for modern applications:
- Full Audit Trail: You get a complete, unalterable history of everything that happened.
- Debugging & Analysis: Easily replay events to understand issues or analyze past behavior.
- Temporal Queries: Reconstruct state at any point in time.
- Resilience: If a read model fails, you can rebuild it by replaying events.
