 ## Setting up fal with other adapter
 
 [fal](http://github.com/fal-ai/fal) offers a Python runtime independent from what database you are using and integrates seamlessly with dbt. It works by downloading the data as a Pandas DataFrame, transforming it in a local Python runtime and uploading it to the database. The only configuration change you need to do is adding it to the `profiles.yml` and setting the `db_profile` property as the database profile you are already using.
