Tutorial: Run dbt Project jaffle_shop

If you're new to dbt, Databend recommends completing the official dbt tutorial available at https://github.com/dbt-labs/jaffle_shop. Before you start, follow Installing dbt-databend-cloud to install dbt and dbt-databend-cloud.

This tutorial provides a sample dbt project called "jaffle_shop," offering hands-on experience with the dbt tool. By configuring the default global profile (~/.dbt/profiles.yml) with the necessary information to connect to your Databend instance, the project will generate tables and views defined in the dbt models directly in your Databend database. Here's an example of the file profiles.yml that connects to a local Databend instance:

~/.dbt/profiles.yml
jaffle_shop_databend:
target: dev
outputs:
dev:
type: databend
host: 127.0.0.1
port: 8000
schema: sjh_dbt
user: databend
pass: ********

If you're using Databend Cloud, you can refer to this Wiki page for step-by-step instructions on how to run the jaffle_shop dbt project.
