• Event-Driven Architecture (EDA): Components emit and react to events asynchronously. This model is scalable, loosely coupled, and ideal for streaming and real-time systems.
  
  
• Request-Driven Architecture: Follows a synchronous request/response pattern (e.g., REST APIs), suitable for transactional operations and interactive user interfaces.

Snowplow supports event-driven workflows by emitting structured, first-party events from user activity, which can then be consumed and processed by event-based systems like Kafka, Flink, or Lambda.
