Apache Airflow

Purpose: Apache Airflow is a platform for programmatically authoring, scheduling, and monitoring workflows.
Workflow language: Airflow workflows are defined in Python code.
Web interface: Its web application lets users monitor, schedule, and manage workflows and view task status and logs.
Scalability: Its modular architecture uses a message queue to orchestrate an arbitrary number of workers.
Workflow fit: Airflow is intended for batch workflows with a clear start and end that run on a schedule.
Operations: The web interface supports manually triggering DAGs, inspecting logs, monitoring task status, backfilling runs, and rerunning failed tasks.
Cloud integrations: Built-in plug-and-play operators support Google Cloud Platform, Amazon Web Services, Microsoft Azure, and other third-party services.
Providers: The community maintains more than 80 separately installable provider packages.
Provider releases: Providers can be upgraded or downgraded independently of the Airflow core release.
Secrets: Airflow can read connections, variables, and configuration from secret backends instead of its database, but secret-backend integrations do not allow writes.
Authentication: Airflow uses JWT authentication for its public REST API and internal Execution API.
Sensitive data: In Airflow 3 and later, sensitive credentials are masked in logs, the UI, and API outputs.
Deployment platforms: Airflow officially supports Linux-based deployment environments; macOS is supported for local development and Windows is unsupported for deployment except WSL2 development.
Community support: The project provides learning resources and community support through Slack and mailing lists.
