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:
