Event-Driven Airflow 3.0: Real-Time Orchestration with Pub/Sub

Traditional time-based scheduling in Airflow can lead to inefficiencies and delays. With Airflow 3.0, we can now leverage native event-driven DAG execution, enabling workflows to trigger instantly when data arrives—eliminating polling-based sensors and rigid schedules. This talk explores real-time orchestration using Airflow 3.0 and Google Cloud Pub/Sub. We’ll showcase how to build an event-driven pipeline where DAGs automatically trigger as new data lands, ensuring faster and more efficient processing. Through a live demo, we’ll demonstrate how Airflow listens to Pub/Sub messages and dynamically triggers dbt transformations only when fresh data is available. This approach improves scalability, reduces costs, and enhances orchestration efficiency. Key Takeaways: How event-driven DAGs work vs. traditional scheduling, Best practices for integrating Airflow with Pub/Sub,Eliminating polling-based sensors for efficiency,Live demo: Event-driven pipeline with Airflow 3.0, Pub/Sub & dbt.

This session will showcase how Airflow 3.0 enables truly real-time orchestration.
