Hi everyone, I've just configured Airbyte open source and I'm trying to understand how the dbt integration works. Airbyte Cloud seems to integrate with DBT Cloud, how does the open source version work?

In the open-source version of Airbyte, the tool in charge of transformation behind the scenes is actually called [dbt](https://blog.getdbt.com/what--exactly--is-dbt-/) (Data Build Tool). Before generating the SQL files, Airbyte sets up a dbt Docker instance and automatically generates a dbt project for you. This is created as specified in the [dbt project documentation page](https://docs.getdbt.com/docs/building-a-dbt-project/projects) with the right credentials for the target destination. The dbt models are then run afterward, thanks to the [dbt CLI](https://docs.getdbt.com/dbt-cli/cli-overview). You can learn more about how to integrate SQL based transformations with Airbyte syncs using dbt in this [tutorial](https://docs.airbyte.com/operator-guides/transformation-and-normalization/transformations-with-dbt). This tutorial is part of a series on transformations, which also includes [Transformations with SQL](https://docs.airbyte.com/operator-guides/transformation-and-normalization/transformations-with-sql) and [Transformations with Airbyte](https://docs.airbyte.com/operator-guides/transformation-and-normalization/transformations-with-airbyte). Please note that custom DBT transformations are currently supported in the open-source version of Airbyte but not in the Cloud version, as mentioned in the [product roadmap](https://app.harvestr.io/roadmap/view/pQU6gdCyc/launch-week-roadmap).
