To get up and running with this project:

1. Clone this repository.

2. Change into the jaffle_shop_duck directory from the command line:

   cd jaffle_shop_duckdb

3. Install dbt and DuckDB in a virtual environment.

   Expand your shell below:

   POSIX bash/zsh

   python3 -m venv venv
   source venv/bin/activate
   python3 -m pip install --upgrade pip
   python3 -m pip install -r requirements.txt
   source venv/bin/activate

   POSIX fish

   python3 -m venv venv
   source venv/bin/activate.fish
   python3 -m pip install --upgrade pip
   python3 -m pip install -r requirements.txt
   source venv/bin/activate.fish

   POSIX csh/tcsh

   python3 -m venv venv
   source venv/bin/activate.csh
   python3 -m pip install --upgrade pip
   python3 -m pip install -r requirements.txt
   source venv/bin/activate.csh

   POSIX PowerShell Core

   python3 -m venv venv
   venv/bin/Activate.ps1
   python3 -m pip install --upgrade pip
   python3 -m pip install -r requirements.txt
   venv/bin/Activate.ps1

   Windows cmd.exe

   python -m venv venv
   venv\Scripts\activate.bat
   python -m pip install --upgrade pip
   python -m pip install -r requirements.txt
   venv\Scripts\activate.bat

   Windows PowerShell

   python -m venv venv
   venv\Scripts\Activate.ps1
   python -m pip install --upgrade pip
   python -m pip install -r requirements.txt
   venv\Scripts\Activate.ps1

   Why a 2nd activation of the virtual environment?

   This may not be necessary for many users, but might be for some. Read on for a first-person report from @dbeatty10.

   I use zsh as my shell on my MacBook Pro, and I use pyenv to manage my Python environments. I already had an alpha version of dbt Core 1.2 installed (and yet another via pipx):

   $ which dbt
   /Users/dbeatty/.pyenv/shims/dbt

   $ dbt --version
   Core:
     - installed: 1.2.0-a1
     - latest:    1.1.1    - Ahead of latest version!
   
   Plugins:
     - bigquery:  1.2.0a1 - Ahead of latest version!
     - snowflake: 1.2.0a1 - Ahead of latest version!
     - redshift:  1.2.0a1 - Ahead of latest version!
     - postgres:  1.2.0a1 - Ahead of latest version!

   Then I ran all the steps to create a virtual environment and install the requirements of our DuckDB-based Jaffle Shop repo:

   $ python3 -m venv venv
   $ source venv/bin/activate
   (venv) $ python3 -m pip install --upgrade pip
   (venv) $ python3 -m pip install -r requirements.txt

   Let's examine where dbt is installed and which version it is reporting:

   (venv) $ which dbt
   /Users/dbeatty/projects/jaffle_duck/venv/bin/dbt

   (venv) $ dbt --version
   Core:
     - installed: 1.2.0-a1
     - latest:    1.1.1    - Ahead of latest version!
   
   Plugins:
     - bigquery:  1.2.0a1 - Ahead of latest version!
     - snowflake: 1.2.0a1 - Ahead of latest version!
     - redshift:  1.2.0a1 - Ahead of latest version!
     - postgres:  1.2.0a1 - Ahead of latest version!

   ❌ That isn't what we expected -- something isn't right. 😢

   So let's reactivate the virtual environment and try again...

   (venv) $ source venv/bin/activate

   (venv) $ dbt --version
   Core:
     - installed: 1.1.1
     - latest:    1.1.1 - Up to date!
   
   Plugins:
     - postgres: 1.1.1 - Up to date!
     - duckdb:   1.1.3 - Up to date!

   ✅ This is what we want -- the 2nd reactivation worked. 😎

4. Ensure your profile is setup correctly from the command line:

   dbt --version
   dbt debug

5. Load the CSVs with the demo data set, run the models, and test the output of the models using the dbt build command:

   dbt build

6. Query the data:

   Launch a DuckDB command-line interface (CLI):

   duckcli jaffle_shop.duckdb

   Run a query at the prompt and exit:

   select * from customers where customer_id = 42;
   exit;
   

   Alternatively, use a single-liner to perform the query:

   duckcli jaffle_shop.duckdb -e "select * from customers where customer_id = 42"

   or:

   echo 'select * from customers where customer_id = 42' | duckcli jaffle_shop.duckdb

7. Generate and view the documentation for the project:

   dbt docs generate
   dbt docs serve

1. Load the CSVs with the demo data set. This materializes the CSVs as tables in your target schema. Note that a typical dbt project does not require this step since dbt assumes your raw data is already in your warehouse.

   dbt seed

2. Run the models:

   dbt run

   NOTE: If you decide to run this project in your own data warehouse (outside of this DuckDB demo) and steps fail, it might mean that you need to make small changes to the SQL in the models folder to adjust for the flavor of SQL of your target database. Definitely consider this if you are using a community-contributed adapter.

3. Test the output of the models using the test command:

   dbt test

Some options:

• duckcli
• DuckDB CLI
• How to set up DBeaver SQL IDE for DuckDB

You may get an error like this, in which case you will need to disconnect from any sessions that are locking the database:

IO Error: Could not set lock on file "jaffle_shop.duckdb": Resource temporarily unavailable

This is a known issue in DuckDB. If you are using DBeaver, this means shutting down DBeaver (merely disconnecting didn't work for me).

Very worst-case, deleting the database file will get you back in action (BUT you will lose all your data).

If you're using a privacy-forward browser such as Firefox and Brave, or a tracking-cookie-blocking extension like UBlock Origin or Privacy Badger, you may see the below error. You can either change your cookie settings, use a browser like Chrome, or just ignore the error because it doesn't affect the demo
