Welcome to Canonicalized! In this blog post, we’ll be discussing how to maximize the benefits of dbt (data build tool) in your data pipeline.
If you’re not familiar with dbt, it’s a framework that helps data analysts and engineers transform and load data into their data warehouse. It was developed by Fishtown Analytics and has quickly become a popular choice among data professionals due to its simplicity and powerful features. dbt provides a simple way to write and manage data transformations and offers features such as testing, documentation, and collaboration.
But how can you make the most out of dbt in your data pipeline? Here are a few tips:
1. Use dbt to standardize your data transformation processes
One of the main benefits of dbt is that it allows you to define your data transformations in code, rather than relying on manual processes or one-off scripts. This makes it easier to maintain your data pipeline and ensure that transformations are consistent over time. It also allows you to version control your data models, which is essential for tracking changes and debugging issues. Additionally, dbt uses Jinja, a templating language, which makes it easier to reuse code and reduce duplication in your data pipeline. This will help you in the long run, as your data models grow and you need to keep track of their dependencies.
2. Take advantage of dbt’s testing and documentation features
dbt includes built-in testing and documentation capabilities, which can help you ensure that your data is accurate and up-to-date.
You can use these features to validate your data and keep track of your transformations. For example, you can use dbt’s “snapshot testing” feature to test the validity of your data models by comparing them to a known “snapshot” of data. You can also use dbt’s documentation generation to generate documentation for your data models, which can be helpful for team members or stakeholders who are unfamiliar with the data.
3. Collaborate with your team
In addition to its testing and documentation capabilities, dbt also includes tools for collaboration. dbt includes features for managing and sharing data models and transformations within your team. This can help ensure that everyone is working with the same data, and make it easier to share knowledge and best practices.
For example, you can use dbt’s “packages” to share reusable code blocks with your team or the community, or use its “profiles” feature to manage connection details for different environments (e.g. staging, production).
4. Use dbt to automate your data pipeline
One of the biggest advantages of dbt is that it can be integrated into your existing data pipeline tools and processes. This allows you to automate the transformation and loading of data into your data warehouse. This can save you time and effort, and help ensure that your data is always up-to-date. For example, you can use dbt with a scheduling tool like Apache Airflow to run your data transformations regularly. You can also use dbt with a version control system like Git to track changes to your data models over time.
5. Utilize dbt’s data governance features
Data governance is an important part of any data pipeline, and dbt helps make it easier. dbt includes features such as user access control, data lineage tracking, and audit logging. This can help ensure that your data is secure and that only authorized users have access to sensitive data. Additionally, data lineage tracking can help you understand how your data is flowing through your data pipeline and identify any potential issues.
6. Leverage dbt’s integration capabilities
In addition to its data transformation, analysis, and governance features, dbt also includes a variety of integration capabilities. This makes it easy to integrate your data pipeline with other tools, such as business intelligence and analytics software. Additionally, dbt provides a variety of connectors for connecting to different data sources, making it easier to pull in data from different sources and load it into your data warehouse. This can help streamline your data pipeline and make it more efficient. Here’s the full list of supported data platforms.
7. Utilize dbt’s support resources
dbt also offers a variety of support resources to help you get the most out of the tool. From the official dbt documentation to the dbt Slack community, there are a variety of resources available to help you get started with dbt and maximize the benefits of your data pipeline.
When building a data pipeline, it is important to have a team of experts who are familiar with dbt and can help you get the most out of the tool. Working with dbt experts can help you take full advantage of the powerful features of dbt and ensure that your data pipeline is optimized for maximum efficiency.
8. Expand dbt’s capabilities with data analysis and visualization tools
dbt is a powerful tool for data transformation, but it does not include data analysis or visualization capabilities. To gain deeper insights into your data, it is recommended to use additional tools such as Tableau, Data Science Notebooks, or other visualization tools. These tools can help you analyze data distributions, explore data correlations, and visualize data with charts and graphs, which can lead to new insights and a better understanding of your data.
9. Building a Robust Data Pipeline with dbt, Airflow, and Great Expectations
Building a robust data pipeline is essential for data-driven decision-making, and by incorporating other powerful tools such as Airflow and Great Expectations, you can truly maximize the benefits of dbt in your data pipeline. Airflow provides a powerful user interface for scheduling and managing data pipelines, and Great Expectations helps ensure that your data is accurate and reliable. Together, dbt, Airflow, and Great Expectations make an unbeatable combination for building a robust data pipeline that will help you make the most out of dbt in your data pipeline.

10. Leverage advanced features
There are many other ways that you can use dbt to improve the efficiency and reliability of your data pipeline. Some additional tips include:
- Use dbt’s “macros” feature to create reusable functions for common data transformations. This can help reduce duplication and make your data models more maintainable.
- Use dbt’s “references” to create relationships between data models. This can make it easier to understand the dependencies between your data models and improve the performance of your data pipeline.
- Use dbt’s “partitions” to optimize the performance of your data models in platforms like BigQuery. This can be particularly useful for large datasets that may take a long time to process.
- Use dbt’s “hooks” and “operations” features to execute custom code at different stages of the data transformation process. This can be useful for performing additional checks or transformations on your data.
The company recently increased the prices for their Cloud offering. dbt Cloud is a paid service that includes additional features and support beyond what is available in the open-source version called dbt Core.
The increase in prices for dbt cloud has caused some controversy in the data community, with some users expressing frustration and disappointment. Some users have also noted that the increased prices may make dbt Cloud less accessible for organizations that heavily rely on the software.
Despite this, dbt remains a popular tool for data pipeline management, and many users continue to find value in both the open-source and cloud offerings. Additionally, there are other alternatives available on the market.
It is important to evaluate the needs of your organization and the resources available before choosing between open-source or cloud. And also, it is always helpful to keep an eye on the pricing structure of the tools you are using as it may change in the future and can affect your organization’s budget.
In conclusion, dbt is a powerful tool that can help you improve the efficiency and reliability of your data pipeline. By leveraging its standardization, testing, documentation, and collaboration features, you can maximize the benefits of dbt and achieve better results from your data transformation projects.
