Data quality is key to the success of an organization’s data systems. In Apache Airflow, implementing data quality checks in DAGs is both easy and effective. With in-DAG quality checks, you can halt pipelines and alert stakeholders before bad data makes its way to a production lake or warehouse.

Executing SQL queries — one of the most common use cases for data pipelines — is a simple way to implement data quality checks. In this webinar, we’ll cover everything you need to know about using SQL for data quality checks, including:

  • How to use the new Common SQL provider
  • How to implement column-level checks
  • How to implement aggregated table-level checks
  • How data quality metrics can be consumed via OpenLineage
  • How to design your pipeline to run, notify, and branch based on the results of data quality checks

Astronomer Webinars are biweekly, real-time online sessions for data pipeline authors hosted by Astronomer’s Apache Airflow experts. During an hour-long meeting, participants have a chance to dive into the most important features and practices related to Apache Airflow and data orchestration — from Airflow 2+ feature highlights to DAG writing best practices. At the end of each webinar, we open the floor to a Q&A to ensure the participants leave the event confident about their newly acquired knowledge.
