dbt DuckDB (EDK preview)

dbt-duckdb from jwills

The dbt-duckdb utility is an adapter-specific dbt transformer for running SQL-based transformations on data stored in your warehouse.

EDK Preview

This utility is in a preview stage of readiness. It is based upon our Extension Developer Kit (EDK) which is the new way to build and add plugins to Meltano Hub. This preview of dbt will replace the native transformer once it comes out of preview. In the meantime, we would appreciate any feedback in the EDK repo and in the dbt Extension repo.

Getting Started


If you haven't already, follow the initial steps of the Getting Started guide:

  1. Install Meltano
  2. Create your Meltano project

Installation and configuration

  1. Add the dbt-duckdb utility to your project using
    meltano add
  2. meltano add utility dbt-duckdb
  3. Configure the dbt-duckdb settings using
    meltano config
  4. meltano config dbt-duckdb set --interactive

Next steps

  1. If you're running dbt for the first time in a new environment:
# create a starter dbt_project.yml file, a profiles.yml file, and models directory
meltano invoke dbt-duckdb:initialize

If you run into any issues, learn how to get help.


This plugin currently has no capabilities defined. If you know the capabilities required by this plugin, please contribute!


Settings for dbt itself can be configured through dbt_project.yml as usual, which can be found at transform/dbt_project.yml in your Meltano project.

The dbt-duckdb settings that are known to Meltano are documented below. To quickly find the setting you're looking for, click on any setting name from the list:

You can override these settings or specify additional ones in your meltano.yml by adding the settings key.

Please consider adding any settings you have defined locally to this definition on MeltanoHub by making a pull request to the YAML file that defines the settings for this plugin.
