Welcome to your guide on leveraging the powerful combination of dbt and Trino for data transformation! In this blog, we’ll walk you through the setup process and tackle some potential hurdles you may encounter. Let’s dive right into it!

What is dbt and Trino?

Before we get started, let’s clarify what dbt and Trino are. Imagine dbt as an accomplished chef who crafts splendid gourmet dishes (data transformations). The kitchen (your data environment) is stocked with various ingredients (data sources), and dbt knows just how to turn those ingredients into a delightful meal (analytical insights). On the other side, we have Trino, which acts like the sous-chef, expertly handling multiple ovens (data connections) to ensure everything is cooking perfectly across different surfaces at once.

Setting Up Your dbt-Trino Connection

To connect your dbt project with Trino, follow these straightforward steps:

• Start by installing dbt:

pip install dbt-trino

• Configure your dbt profile for Trino or Starburst. This involves updating profiles.yml with your connection details. For detailed guidelines, refer to Starburst and Trino Setup.
• Ensure you are familiar with the necessary configurations specific to Trino and Starburst. Visit Starburst (Trino) configurations for more insights.

Troubleshooting Common Issues

While connecting dbt and Trino is typically smooth sailing, here are some common issues and how to troubleshoot them:

• Authentication Failures: Ensure that your credentials in profiles.yml are accurate. Sometimes, a missing character can cause headaches.
• Connection Issues: If you experience timeouts or cannot establish a connection, check your network settings or firewall configurations that may block access to Trino.
• SQL Query Failures: If you receive errors about SQL syntax or transformations, double-check your dbt model definitions. Each piece must align with SQL syntax supported by Trino.
