Overview

Concrete tool for mapping Airflow starrocks connections to dbt starrocks profiles provided by astronomer-cosmos. This is a community-contributed profile mapping.

Description

The StarRocksUserPasswordProfileMapping maps an Airflow starrocks connection to a dbt starrocks profile. It translates connection parameters (host, login, password, schema, port, extras) into the YAML structure that dbt expects in `profiles.yml`. This is a community-contributed adapter (is_community=True).

Usage

Use this profile mapping when configuring Cosmos to run dbt commands against a StarRocks backend. Assign it to `ProfileConfig(profile_mapping=...)` when the target Airflow connection uses the `starrocks` connection type.
