What is Apache Airflow?

Apache Airflow is an open-source platform for programmatically scheduling and monitoring workflows, also known as DAGs (Directed Acyclic Graphs). It is a powerful tool for automating and managing complex tasks, making it an ideal choice for enterprise automation. With Apache Airflow, you can define, schedule, and monitor workflows as a directed acyclic graph (DAG) of tasks. This allows you to manage complex dependencies and relationships between tasks, making it easier to automate and manage workflows.
