    name: event-driven

    Event-Driven Architecture

    Event Schema

    { eventId, eventType, timestamp, version, data, metadata }

    Broker Choice

    • Kafka: throughput, ordering, replay
    • SQS: simpler, managed
    • RabbitMQ: flexible routing

    Saga Pattern

    1. Order created → 2. Payment charged → 3. Stock reserved
    If any fails → compensating events

    CQRS

    • Write model: normalized
    • Read model: denormalized
    • Sync via events
