Overview

Concrete tool for mapping Airflow trino connections to dbt trino profiles using certificate authentication, provided by astronomer-cosmos.

Description

The TrinoCertificateProfileMapping maps an Airflow trino connection to a dbt trino profile using the certificate authentication method. It extends TrinoBaseProfileMapping and sets `method="certificate"`, translating connection parameters into the YAML structure that dbt expects in `profiles.yml`.

Usage

Use this profile mapping when configuring Cosmos to run dbt commands against a Trino backend. Assign it to `ProfileConfig(profile_mapping=...)` when the target Airflow connection uses the `trino` connection type with certificate-based authentication.
