Enterprises want the flexibility to operate across multiple clouds, whether to optimize costs, improve resiliency, to avoid vendor lock-in, or for data sovereignty. But for developers, that flexibility usually comes at the cost of extra complexity and redundant code. The goal here is simple: write once, run anywhere, with minimum boilerplate. In Apache Airflow, we’ve already begun tackling this problem with abstractions like Common-SQL, which lets you write database queries once and run them on 20+ databases, from Snowflake to Postgres to SQLite to SAP HANA. Similarly, Common-IO standardizes cloud blob storage interactions across all public clouds. With Airflow 3.0, we are pushing this further by introducing a Common Message Bus provider, which is an abstraction, initially supporting Amazon SQS and expanding to Google PubSub and Apache Kafka soon after. We expect additional implementations such as Amazon Kinesis and Managed Kafka over time. This talk will dive into why these abstractions matter, how they reduce friction for developers while giving enterprises true multi-cloud optionality, and what’s next for Airflow’s evolving provider ecosystem.

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.

Airflow 3 introduces a major evolution in orchestration: native support for external event-driven scheduling. In this talk, I’ll share the journey behind AIP-82—why we needed it, how we built it, and what it unlocks. I’ll dive into how the new AssetWatcher enables pipelines to respond immediately to events like file arrivals, API calls, or pub/sub messages. You’ll see how this drastically reduces latency and infrastructure overhead while improving reactivity and resource efficiency. We’ll explore how it works under the hood, real-world use cases, best practices, and migration tips for teams ready to shift from time-based to event-driven workflows. If you’re looking to make your Airflow DAGs more dynamic, this is the talk that shows you how. Whether you’re an operator or contributor, you’ll walk away with a deep understanding of one of Airflow 3’s most impactful features.
