Apache Airflow

I. Introduction

Product Name: Apache Airflow

Brief Description: Apache Airflow is an open-source platform to programmatically author, schedule, and monitor workflows. It uses a directed acyclic graph (DAG) model to define workflows as code, enabling easy visualization, versioning, and collaboration.

II. Project Background

  • Library/Framework: Apache Software Foundation
  • Authors: Airbnb (original creators)
  • Initial Release: 2014
  • Type: Workflow management and orchestration
  • License: Apache License 2.0

III. Features & Functionality

  • Workflow Orchestration: Defines and schedules complex workflows as DAGs.
  • Task Dependency Management: Manages dependencies between workflow tasks.
  • Task Scheduling: Schedules tasks based on various triggers and dependencies.
  • Monitoring and Alerting: Provides visibility into workflow execution and alerts for failures.
  • Extensibility: Offers a rich plugin architecture for custom operators and integrations.
  • User Interface: Provides a web interface for workflow management and monitoring.

IV. Benefits

  • Improved Workflow Visibility: Visualizes and monitors workflow execution.
  • Increased Productivity: Automates and schedules repetitive tasks.
