1.4.2. When to Choose Streaming

Choose streaming when:

  • Business value degrades with delay (fraud detection, stock trading)
  • Events must trigger immediate actions
  • Data arrives continuously with no natural batch boundary
  • Users expect real-time dashboards

Fabric tools for streaming: Eventstreams, KQL Databases, Spark Structured Streaming, Real-Time Intelligence

⚠️ Exam Trap: The exam tests whether you can match business requirements to processing paradigms. "Near real-time" doesn't always mean streaming—if "near real-time" means hourly refreshes, batch scheduling is the simpler answer.
