Orchestrate your dbt projects in Airflow

---

Run your dbt Core projects as Apache Airflow DAGs and Task Groups with a few lines of code. Benefits include:

• Run dbt projects against Airflow connections instead of dbt profiles

• Native support for installing and running dbt in a virtual environment to avoid dependency conflicts with Airflow

• Run tests immediately after a model is done to catch issues early

• Utilize Airflow’s data-aware scheduling to run models immediately after upstream ingestion

• Turn each dbt model into a task/task group complete with retries, alerting, etc.

Quickstart

Check out the Getting Started guide on our docs. See more examples at /dev/dags and at the cosmos-demo repo.

Example Usage

You can render a Cosmos Airflow DAG using the DbtDag class. Here’s an example with the jaffle_shop project:

This will generate an Airflow DAG that looks like this:
