What is Apache Airflow?
Apache Airflow is an open-source platform that allows you to programmatically author, schedule, and monitor workflows. Workflows are represented as Directed Acyclic Graphs (DAGs), where each node represents a task, and the edges define the dependencies between these tasks. The significance of Airflow lies in its ability to handle complex workflows in a clear and efficient manner. It provides data engineers with a structured approach to manage their ETL (Extract, Transform, Load) processes, business operations, and even MLOps. With Airflow, you can visualize your workflow, monitor progress, and troubleshoot issues seamlessly.
Key Features of Apache Airflow
Airflow boasts several key features that make it a preferred choice for managing workflows:
- DAGs (Directed Acyclic Graphs): You can define workflows as DAGs, allowing for clear visualization of task dependencies and execution flow.
- Scheduling: Airflow provides powerful scheduling capabilities, enabling you to run tasks at specified intervals or trigger them based on certain events.
