Apache Airflow is an open-source platform for orchestrating complex workflows and data pipelines. It allows users to schedule, monitor, and manage workflows as directed acyclic graphs (DAGs). Airflow is widely used for automating and orchestrating tasks in data engineering, machine learning, and other domains.
Workflows in Apache Airflow are defined as directed acyclic graphs (DAGs), where nodes represent tasks and edges define the sequence of task execution. Each task is a unit of work, and dependencies between tasks are explicitly defined, allowing for flexible and dynamic workflow execution.
Key components include the Airflow Scheduler (for managing task scheduling and execution), the Airflow Web Server (providing a user interface for DAG management), the Metadata Database (storing metadata and configuration), and Executors (defining how tasks are executed).
Apache Airflow supports dynamic workflows by allowing the definition of dynamic DAGs and tasks at runtime. Workflows can also be parameterized using Jinja templating, enabling the dynamic configuration of tasks based on parameters or external variables.
Unlike traditional schedulers, Apache Airflow provides a more expressive and dynamic way to define, schedule, and monitor workflows. It allows for complex dependencies between tasks, retries on failure, dynamic workflow generation, and a centralized web interface for monitoring and managing workflows.
