Core Concepts
Understanding the fundamental concepts behind event sourcing and how they are implemented in ReckonDB.
What is Event Sourcing?
Event sourcing is a design pattern where the state of your application is determined by a sequence of events. Instead of storing just the current state, event sourcing stores all changes to the application state as a sequence of events.
Key Concepts
Events
Immutable facts that represent something that happened in your domain.
Event Store
The append-only log where events are stored.
Projections
Different views of your data built from the event stream.
Snapshots
Point-in-time captures of aggregate state for performance optimization.
