Event-Driven Architecture Patterns
Expert guidance for designing, implementing, and operating event-driven systems with proven patterns for event sourcing, CQRS, message brokers, saga coordination, and eventual consistency management.
When to Use This Skill
- Designing systems with asynchronous, decoupled communication
- Implementing event sourcing and CQRS patterns
- Building systems requiring eventual consistency and high scalability
- Managing distributed transactions across microservices
- Processing real-time event streams and data pipelines
- Implementing publish-subscribe or message queue architectures
- Designing reactive systems with complex event flows
Core Principles
1. Events as First-Class Citizens
Events represent immutable facts that have occurred in the system. Use past tense naming (OrderCreated, PaymentProcessed) and include all necessary context.
