Introduction to Airflow
Apache Airflow is an open source tool for programmatically authoring, scheduling, and monitoring data pipelines. It has over 9 million downloads per month and an active OSS community. Airflow allows data practitioners to define their data pipelines as Python code in a highly extensible and infinitely scalable way.
A great way to explore Airflow features and use cases is using Astronomer's Airflow Quickstart.
