Overview

Concrete tool for mapping Airflow snowflake connections to dbt snowflake profiles provided by astronomer-cosmos.

Description

The SnowflakeUserPasswordProfileMapping maps an Airflow snowflake connection to a dbt snowflake profile. It translates connection parameters (host, login, password, schema, port, extras) into the YAML structure that dbt expects in `profiles.yml`. This is the standard user/password authentication variant.

Usage

Use this profile mapping when configuring Cosmos to run dbt commands against a Snowflake backend. Assign it to `ProfileConfig(profile_mapping=...)` when the target Airflow connection uses the `snowflake` connection type with username and password authentication.
