Welcome to the Apache Airflow Cookbook! This section provides practical examples and recipes for common Airflow use cases, helping you build robust and efficient data pipelines.
Getting Started
Before diving into specific recipes, ensure you have a basic understanding of Airflow concepts like DAGs, Operators, Tasks, and Connections.
Recipes
-
Triggering a DAG Run
Learn how to programmatically trigger other DAGs or specific DAG runs using Airflow's API and operators.
-
Managing Connections
Discover best practices for configuring and managing connections to various external services and databases.
-
Creating Custom Operators
Extend Airflow's functionality by building your own custom operators tailored to your specific needs.
-
Generating DAGs Dynamically
Explore techniques for creating DAGs on the fly based on external configurations or discovery.
-
Passing Data Between Tasks (XComs)
Understand how to use XComs to pass small amounts of metadata or results between tasks in a DAG.
-
Working with Sensors
Learn how to use sensors to wait for specific conditions to be met before proceeding with your pipeline.
-
Advanced Scheduling Strategies
Dive into more complex scheduling scenarios, including cron expressions, time deltas, and triggers.
-
Monitoring and Alerting
Set up effective monitoring and alerting mechanisms to keep track of your DAGs' health and performance.
Common Patterns
Here are some common patterns you'll encounter when building Airflow pipelines:
- ETL/ELT Pipelines: Extract, Transform, and Load data from various sources.
- Data Quality Checks: Implement automated checks to ensure data integrity.
- Machine Learning Workflows: Orchestrate model training, evaluation, and deployment.
- Reporting and Analytics: Automate the generation of reports and dashboards.
