Apache Airflow

Apache Airflow is a community-driven, open-source workflow orchestration platform that lets data engineers and developers define pipelines as Python code. It provides a modular, scalable architecture built around a message queue that can orchestrate an arbitrary number of workers. Airflow's web UI offers real-time monitoring, scheduling, and management of all workflows, while its extensive provider ecosystem enables plug-and-play integrations with virtually every major cloud and data platform.

• Pure Python Pipelines: Define DAGs (Directed Acyclic Graphs) entirely in Python — no XML or command-line magic required — enabling dynamic pipeline generation with loops, conditionals, and date-time scheduling.
• Scalable Architecture: Airflow's modular design uses a message queue to distribute work across an arbitrary number of workers, scaling from a single machine to large distributed clusters.
• Robust Web UI: Monitor, schedule, and manage workflows through a modern web application that provides full visibility into task status, logs, and historical runs.
• Extensible Operator Library: Easily define custom operators and extend existing libraries to match your environment's abstraction level.
• Jinja Templating: Parametrize pipelines elegantly using the built-in Jinja templating engine for clean, explicit pipeline definitions.
• Helm Chart & Docker Support: Deploy Airflow on Kubernetes using the official Helm Chart, or use the official Docker image for containerized deployments.
• Task SDK: Decouple DAG authoring from Airflow internals with the Task SDK, providing a stable, forward-compatible interface for writing tasks across Airflow versions.
• Provider Packages: Access 90+ independently versioned provider packages for integrations with Google Cloud, AWS, Azure, Snowflake, Databricks, dbt Cloud, Kafka, Spark, and many more.
• REST API & Python Client: Interact with Airflow programmatically via the official REST API and Python API client.
• Active Open-Source Community: Contribute via GitHub pull requests with no barriers; join a large Slack community for support and knowledge sharing.
