The Asset Catalog captures Airflow assets (Dags, tasks, datasets) and data assets (tables) that are automatically emitted during Airflow job runs. Assets in Astro represent the storage and movements of data through Airflow jobs.
Astro Assets are distinct from Airflow Assets, a user-defined logical grouping of data. Astro Assets include but aren’t limited to Airflow Assets.
You can find a list of assets in your Organization in the Asset Catalog page of Observe.
After your Dags run at least once, Observe automatically stores information about the tasks, datasets, warehouse tables, and local files you use in your Dags as Assets. You can then find these assets in the Asset Catalog.
