Analytical SQL and Data Warehouses built BookNest's warehouse models in dbt 37,942 , and Writing DAGs ran them from Airflow 129 with one BashOperator. That works, but Airflow then sees a single box where dbt sees a graph of models and tests. This section renders that graph as Airflow tasks with Astronomer 149,584 Cosmos, on dbt Core and on dbt's new engine.
