The talk will cover how we use Airflow at the heart of our Workflow Management Platform(WFM) at Booking.com, enabling our internal users to orchestrate big data workflows on Booking Data Exchange(BDX). High level overview of the talk: Adapting open source Airflow helm chart to spin up Airflow installation in Booking Kubernetes Service (BKS) Coming up with Workflow definition format (yaml) Conversion of workflow.yaml to workflow.py DAGs Usage of Deferrable operators to provide standard step templates to users Workspaces (collection of workflows), using it to ensure role based access to DAG permissions for users Using okta for authentication Alerting, monitoring, logging Plans to shift to Astronomer

As organizations grow, the task of creating and managing Airflow DAGs efficiently becomes a challenge. In this talk, we will delve into innovative approaches to streamlining Airflow DAG creation using YAML. By leveraging YAML configuration, we allow users to dynamically generate Airflow DAGs without requiring Python expertise or deep knowledge of Airflow primitives. We will showcase the significant benefits of this approach, including eliminating duplicate configurations, simplifying DAG management for a large group of workflows, and ultimately enhancing productivity within large organizations. Join us to learn practical strategies to optimize workflow orchestration, reduce development overhead, and facilitate seamless collaboration across teams.
