Apache Airflow

Apache Airflow is an open-source platform for authoring, scheduling, and monitoring workflows as Directed Acyclic Graphs (DAGs). It allows users to programmatically define complex data pipelines using Python, enabling dynamic task generation, dependency management, and execution across distributed systems. Airflow is designed for scalability, extensibility, and ease of use, making it a popular choice for orchestrating ETL processes, machine learning workflows, and business operations.

Features

• Python-based workflow definition using DAGs
• Dynamic pipeline generation with Jinja templating
• Rich web UI for monitoring, triggering, and debugging workflows
• Modular architecture with pluggable executors and operators
• Extensive integrations with cloud platforms (AWS, GCP, Azure)
• Built-in support for retries, alerts, and SLA monitoring
• Versioning and parametrization of workflows
• REST API for programmatic interaction
• Plugin system for custom extensions
• Role-based access control and authentication support

Capabilities

• Orchestration of batch and streaming data workflows
• Scheduling and execution of tasks with dependency resolution
• Distributed execution using Celery, Kubernetes, or Dask executors
• Integration with external systems via custom and prebuilt operators
• Metadata tracking and audit logging
• DAG versioning and backfill support
• Triggering workflows based on events or external inputs
• Extensible architecture for custom sensors, hooks, and operators
• Deployment on-premises or in cloud-native environments
