Event-Driven Architecture Patterns

Event Sourcing Pattern

Problem: Need complete audit trail of all changes to application state.

Solution: Use an append-only store to record the full series of events that describe actions taken on data in a domain.

When to Use:

  • Requiring complete audit trail
  • Implementing temporal queries (point-in-time state)
  • Supporting event replay and debugging
  • Implementing CQRS with eventual consistency

Implementation Considerations:

  • Store events in append-only log
  • Rebuild current state by replaying events
  • Implement event versioning strategy
  • Handle event schema evolution
  • Consider storage growth over time
  • Implement snapshots for performance
