Imagine a whimsical world where an imaginary postcard company thrives, flitting across the European landscape, selling its vibrant creations both directly and through resellers. Now, imagine arming this company with a powerful analytics suite that helps it navigate the waters of data, orchestrated seamlessly. Welcome to the Portable Data Stack, a magic toolbox designed to gather, manage, and analyze data with style. In this blog, we’ll walk you through the process of setting up this analytics suite, helping you conjure the insights you need to succeed.

Understanding the Components of the Stack

The Portable Data Stack consists of a mixture of modern tools that work together like a well-rehearsed orchestra, each playing its part perfectly:

• Dagster: The conductor of our data orchestration.
• Docker: The container that holds our instruments—ensuring they all play in harmony.
• DuckDB: Our speedy data warehouse, allowing us to store and query the data efficiently.
• dbt core: The modeler that structures our data into cohesive narratives.
• Superset: The visual maestro, giving a face to our numbers through elegant dashboards.

Getting Started: System Requirements and Setup

Let’s embark on our journey to set up the Portable Data Stack.

System Requirements

Before diving in, ensure you have Docker installed on your machine. You can find installation instructions here.

Setup Instructions

1. Begin by renaming .env.example to .env and specify your desired password. Remember: sensitive information is a secret, so don’t commit it!
2. Rename shared/db/datamart.duckdb.example to shared/db/datamart.duckdb, or alternatively, create an empty database file there.
3. With Docker Engine installed, navigate to the root folder of the project (where docker-compose.yml resides) and run:

   docker compose up --build

4. Once the Docker suite is up and running, access the Dagster interface at localhost:3000 and materialize the selected assets.
5. After materialization, explore the data through the Superset interface.

General Flow of Data Manipulation

Now that our tools are ready, let’s look at how data flows through this stack, using an engaging analogy:

Think of our setup as a vibrant bakery. We first bake our imaginary cupcakes (data generation) using kitchen appliances (Python scripts). Once baked, we carefully arrange them (import flat file and OLTP data into DuckDB, orchestrated by Dagster), then we skillfully decorate them (modeling data and building tables using dbt). Finally, we present our beautifully crafted cupcakes on a display case (analyzing data with Superset), inviting customers to delight in their flavors (data insights).

Troubleshooting Your Setup

While our journey so far is smooth sailing, you may encounter some bumps in the road. Here are a few troubleshooting ideas:

• Docker not starting? Ensure that Docker is properly installed and running. Check for any conflicts with other services running on your machine.
• Dagster or Superset not accessible? Verify that the ports (3000 for Dagster and 8088 for Superset) are not blocked by firewall or other software.
• Data not materializing? Double-check that all environmental variables in your `.env` file are correctly set.
