Event sourcing is an architectural pattern where state changes are stored as a sequence of events. The current state is rebuilt by replaying these events.
Key Concepts
Event store
Event versioning
Snapshots for performance
Projections
Temporal queries
Common Use Cases
Audit trails required
Complex state changes
Temporal queries
Rebuilding state
Distributed systems
Best Practices
Version events carefully
Implement snapshotting
Design immutable events
Use idempotent handlers
Consider event size

Consider event sourcing for domains where audit trails and temporal queries provide significant business value, and where the complexity trade-off is justified.
