BigData / Apache Airflow Interview Questions
What is Apache Airflow?
Apache Airflow is an open-source platform for programmatically authoring, scheduling, and monitoring workflows. Originally created at Airbnb in 2014 and donated to the Apache Software Foundation, Airflow lets you define workflows as Directed Acyclic Graphs (DAGs) written in Python. The scheduler executes tasks on an array of workers while following the specified dependencies. The rich UI makes it easy to visualize pipelines running in production, monitor progress, and troubleshoot issues.
Key capabilities include dynamic pipeline generation, extensible operators, and a web-based UI for visibility into pipeline state.
