90% of Airflow users run ETL/ELT pipelines. Here’s how they do it.

Hi John,

ETL and ELT pipelines are the backbone of every data product, but without clear patterns and best practices, they can quickly become fragile and hard to maintain. When that happens, your data misses the right location or format, and every downstream workflow suffers for it.

Best Practices for ETL and ELT Pipelines is the comprehensive guide to designing pipelines the way expert teams do, now updated with the latest capabilities in Airflow 3.

You’ll learn how to:

• Make key architectural decisions when designing ETL/ELT pipelines
• Apply Dag writing best practices, including testing strategies and scaling options
• Use Airflow 3 features like dynamic task mapping, data-aware scheduling, and custom task groups

Plus, you’ll also get a pre-flight checklist that helps ensure you’re taking the right approach before you begin coding.
