??Article 1: Setting Up dbt with Databricks ??: Supercharge Your Data Transformations!
Hey there, Are you looking to supercharge your data transformations using the powerful combination of dbt and Databricks? In this article, we’ll walk through the steps to set up dbt with Databricks, enabling you to streamline your data transformation workflows and unlock the true potential of your data. Let’s dive in!
?? Why dbt and Databricks?
Before we begin, let’s understand why dbt and Databricks are a match made for your data transformation needs. dbt provides a structured and collaborative framework for managing your data transformations, allowing you to define models, run transformations, and ensure data quality through tests. On the other hand, Databricks offers a scalable and powerful environment for data processing and analytics, leveraging technologies like Apache Spark. Combining these two tools empowers you to accelerate your data transformation pipelines and drive data insights like never before.
?? Setting Up Your Environment
To set up dbt with Databricks, follow these steps:
1?? Create a dbt Cloud Account: Sign up for a dbt Cloud account if you haven’t already. dbt Cloud provides a collaborative and managed environment for running dbt projects.
2?? Create a dbt Project: Initialize a new dbt project.
3?? Configure Databricks Connection ??: configure the connection to your Databricks workspace. Add the necessary credentials, including the Databricks workspace URL, token, and cluster information. This will enable dbt to connect to your Databricks environment.
4?? Verify the Connection: To ensure the connection is established, click on the Test connection button. dbt will validate the connection settings and provide feedback on the connection status.
5?? Ready to Go!: With the connection successfully established, you’re now ready to leverage the power of dbt with Databricks. You can define models, write transformations in SQL or Jinja, and execute them against your Databricks cluster.
?? Getting Started with dbt and Databricks
To kickstart your data transformation journey with dbt and Databricks, try creating a simple dbt model. Define a model in the models directory of your dbt project, write SQL or Jinja code to transform your data, and save the output to a new table or view. Execute the model using the dbt run command, and dbt will orchestrate the transformation process and execute it on your Databricks cluster.

Note?: make sure to load and create tables in databricks based on those 3 data files before you run this code
with customers as (
select
id as customer_id,
first_name,
last_name
from jaffle_shop_customers
),
orders as (
select
id as order_id,
user_id as customer_id,
order_date,
status
from jaffle_shop_orders
),
customer_orders as (
select
customer_id,
min(order_date) as first_order_date,
max(order_date) as most_recent_order_date,
count(order_id) as number_of_orders
from orders
group by 1
),
final as (
select
customers.customer_id,
customers.first_name,
customers.last_name,
customer_orders.first_order_date,
customer_orders.most_recent_order_date,
coalesce(customer_orders.number_of_orders, 0) as number_of_orders
from customers
left join customer_orders using (customer_id)
)
select * from final
Execute the model using the dbt run command, and dbt will orchestrate the transformation process and execute it on your Databricks cluster.
In Databricks schema, you will find the table customers created
