dbt-postgres - Meltano Hub

dbt PostgreSQL

dbt-postgres (dbt-labs variant)

The dbt-postgres utility is an adapter-specific dbt transformer for running SQL-based transformations on data stored in your warehouse. This utility plugin is meant to be used in favor of the dbt-postgres transformer plugin type. Note that this plugin can only be run as part of an ELT pipeline with the meltano run command. If you are using meltano elt you should use the transformer plugins. We do recommend migrating to meltano run as the transformer plugin type will be deprecated in a future major Meltano release.

EDK Based Plugin

This utility is based on the Meltano Extension Developer Kit (EDK) which is the preferred way to build and add non-Singer plugins to Meltano Hub. For more information about the EDK, please read this section of the Meltano docs. If you have any feedback or suggestions, add them to the EDK repo.

Getting Started

Prerequisites

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

Installation and configuration

Add the dbt-postgres utility to your project using
```
meltano add
```
:

meltano add utility dbt-postgres

Configure the dbt-postgres settings using

meltano config

:

meltano config dbt-postgres set --interactive

Next steps

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-postgres:initialize

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

Capabilities

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

Settings

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. dbt also has adapter-specific documentation for PostgreSQL.

The dbt-postgres 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:

dbname
host
keepalives_idle
password
port
profiles_dir
project_dir
role
schema
search_path
skip_pre_invoke
sslmode
target_path
type
user

You can also list these settings using

meltano config

with the list subcommand:

meltano config dbt-postgres 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.
