Event — Event-Driven Architecture Reference

Quick-reference skill for event-driven architecture, event sourcing, pub/sub patterns, and stream processing.

When to Use

• - Designing event-driven microservice architectures
• Implementing pub/sub or event bus patterns
• Building event sourcing and CQRS systems
• Choosing between event brokers (Kafka, RabbitMQ, etc.)
• Handling event ordering, idempotency, and exactly-once semantics
