In this section, we will set up the necessary components to learn dbt.
We'll create a BigQuery data warehouse on Google Cloud, load data, and configure permissions. Then, we'll create a dbt Cloud account, connect it to BigQuery, and link our dbt project to a GitHub repository.
Link to project repository: https://github.com/insightahead/dbt-learning-project
We'll create a Google Cloud account, set up a BigQuery instance, and load data into the instance for dbt to later transform.
We'll also create a storage bucket to store data and ensure proper access settings.
Finally, we'll create a BigQuery dataset and tables within it to prepare for working with dbt.
In this lecture, we created tables inside our dataset using data from the files uploaded to our bucket.
Instead of manually creating 24 tables, we used a script to automate the process.
In this lecture, we'll create a dbt cloud account and link it to our BigQuery instance.
We'll sign up for a free dbt cloud account, create a project, and choose BigQuery as our data warehouse. Next, we'll configure the connection by creating a service account JSON file with the necessary credentials in BigQuery. After uploading the JSON file to dbt and testing the connection, we'll have successfully set up our dbt cloud account
In this lecture, we will set up our code repository using GitHub.
We will create a GitHub account, link it to our dbt Cloud account, and configure the repository settings.
We will then create a new repository on GitHub and connect it to our dbt Cloud project.
To ensure everything is correctly set up, we run a dbt command in the dbt Cloud IDE to build our first model in BigQuery.
After attending this lecture, you will gain an understanding of SQL models in dbt and their role in organizing business logic using SELECT statements and Common Table Expressions (CTEs).
By the end of this lecture, you will be able to set up a development environment in dbt, create branches, and use a Git workflow to manage your dbt project.
You will also be able to create and configure a simple dbt model, write SQL queries to manipulate and transform data and preview and execute models on a data warehouse platform like Google BigQuery.
After completing this lecture, you will understand the importance of staging in a data engineering pipeline and learn how to model the staging area in dbt.
You will explore the different transformations applied in the staging area.
By the end of this lecture, you will be able to identify the challenges and limitations of directly selecting raw data in dbt models.
You will learn about declaring and configuring a dbt source in a YAML file.
Additionally, you will explore how to use the source function to reference sources in dbt models for improved data management and gain hands-on experience in building your first source in dbt to enhance data pipeline flexibility and maintainability.
By the end of this lecture, you will be able to create and configure a dbt source YAML file, understand the importance of accurate indentation in YAML files, and learn how to troubleshoot parsing errors.
By the end of the lecture, you will be able to:
Utilize the source function effectively in data models.
Troubleshoot and fix common errors in data models.
Differentiate between project name and project ID in Google BigQuery.
Run and test SQL queries in the BigQuery editor.
Create and maintain data lineage in data models.
Apply version control practices for data model changes.
By the end of this lecture, you will be able to:
Add tests to a dbt source for data validation.
Use UNIQUE and NOT NULL tests to ensure data integrity.
Implement ACCEPTED VALUE tests for columns with a limited set of values.
Debug and resolve issues with test execution.
Utilize dbt Cloud IDE to run tests and analyze test results.
Understand the concept of dbt packages and their benefits.
Utilize the dbt hub for finding and implementing packages in your project.
Understand how to add the dbt code generation package to a project and create a packages.yml file.
Learn how to call and use macros in dbt, such as the generate source macro.
Explore ways to customize the generated source definitions, such as adding column names and descriptions.
Learn how to utilize the dbt hub and its packages to create staging models for each source in a project efficiently.
Understand the importance of documentation in dbt projects.
Learn how to add descriptions to sources, models, tables, and columns.
Discover how to generate and view the documentation for your dbt project.
Navigate the documentation page to understand the structure of your project and its components.
Understand the purpose and importance of the ref function in dbt.
Learning how to reference existing models using the ref function and Jinja syntax in dbt
Learning how to build a Directed Acyclic Graph (DAG) in dbt to visualize the dependencies between models
Learn how to use the dbt-codegen package to generate YAML for models.
Familiarize yourself with other useful macros available in the dbt-codegen package.
Know how to add descriptions, documentation, and tests to models in YAML files
Understand the purpose of a pull request or a merge request
Understand the importance of code review and collaboration when merging changes to the main branch
Be aware of the concept of environments in dbt and understand their purpose in deployment
Understand the concept of environments in dbt.
Understand the purpose of deployment environments in dbt.
Navigate to the environments section in dbt Cloud IDE.
Create a production environment with a specific dbt version.
Configure deployment credentials according to the warehouse being used.
Understand the components and purpose of a dbt job in a deployment environment.
Learn how to create and configure a dbt job, including specifying the environment, target name, and execution settings.
Explore the dbt build command and its role in running models, tests, snapshots, and seeds.
Execute a dbt job and monitor its progress from the queued state to successful completion.
Learn how to configure a dbt job to run on a schedule, including selecting specific days and times.
Explore custom cron schedules for more precise control over job execution timings.
Monitor and manage scheduled jobs, including viewing run history and generated documentation.
The dbt init command initializes a new dbt Core project
dbt clean deletes folders listed in the clean-targets of dbt_project.yml, often used for dbt_packages and target directories. It doesn't work with the dbt Cloud IDE'.
In dbt Cloud, dbt deps auto-cleans before installing packages, and the target folder can be removed manually from the sidebar.
