Amazon SageMaker Canvas is a no-code machine learning platform that lets you generate predictions, prepare data, and build models without writing code. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Databricks data for building custom machine-learning models, predicting customer churn, generating texts, building chatbots, and more. This article shows how to connect to Connect AI from Amazon SageMaker Canvas using the RDS connector and integrate live Databricks data into your ML model deployments.
CData Connect AI provides a pure SQL, cloud-to-cloud interface for Databricks, allowing you to easily integrate with live Databricks data in Amazon SageMaker Canvas β without replicating the data. CData Connect AI looks exactly like a SQL Server database to Amazon SageMaker Canvas and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Databricks, leveraging server-side processing to quickly return Databricks data.
About Databricks Data Integration
Accessing and integrating live data from Databricks has never been easier with CData. Customers rely on CData connectivity to:
- Access all versions of Databricks from Runtime Versions 9.1 - 13.X to both the Pro and Classic Databricks SQL versions.
- Leave Databricks in their preferred environment thanks to compatibility with any hosting solution.
- Secure authenticate in a variety of ways, including personal access token, Azure Service Principal, and Azure AD.
- Upload data to Databricks using Databricks File System, Azure Blog Storage, and AWS S3 Storage.
While many customers are using CData's solutions to migrate data from different systems into their Databricks data lakehouse, several customers use our live connectivity solutions to federate connectivity between their databases and Databricks. These customers are using SQL Server Linked Servers or Polybase to get live access to Databricks from within their existing RDBMs.

Getting Started
Configure Databricks Connectivity for Amazon SageMaker Canvas
Connectivity to Databricks from Amazon SageMaker Canvas is made possible through CData Connect AI. To work with Databricks data from Amazon SageMaker Canvas, we start by creating and configuring a Databricks connection.
-
Log into Connect AI, click Sources, and then click Add Connection
π Adding a Connection
- Select "Databricks" from the Add Connection panel
π Selecting a data source
-
Enter the necessary authentication properties to connect to Databricks.
To connect to a Databricks cluster, set the properties as described below.
Note: The needed values can be found in your Databricks instance by navigating to Clusters, and selecting the desired cluster,
and selecting the JDBC/ODBC tab under Advanced Options.
- Server: Set to the Server Hostname of your Databricks cluster.
- HTTPPath: Set to the HTTP Path of your Databricks cluster.
- Token: Set to your personal access token (this value can be obtained by navigating to the User Settings page of your Databricks instance and selecting the Access Tokens tab).
π Configuring a connection (Salesforce is shown)
-
Click Save & Test
-
Navigate to the Permissions tab in the Add Databricks Connection page and update the User-based permissions.
π Updating permissions
Add a Personal Access Token
When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.
-
Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
-
On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
π Creating a new PAT
-
The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Databricks data from Amazon SageMaker Canvas.
Connecting to CData Connect AI from Amazon SageMaker Canvas
With the connection in CData Connect AI configured, you are ready to integrate live Databricks data into Amazon SageMaker Canvas using its RDS connector.
- Select a domain and user profile in Amazon SageMaker Canvas and click on "Open Canvas".
π Open SageMaker Canvas application
- Once the Canvas application opens, navigate to the left panel, and select "My models".
π Select My models
- Click on "Create new model" in the My models screen.
- Specify a Model name in Create new model window and select a Problem type. Click on "Create".
π Create a new model
- Once the model version gets created, click on "Create dataset" in the Select dataset tab.
π Select a dataset
- In the Create a tabular dataset window, add a "Dataset name" and click on "Create".
π Create a tabular dataset
- Click on the "Data Source" drop-down and search for or navigate to the RDS connector and click on " Add Connection".
π Select RDS connector
- In the Add a new RDS connection window, set the following properties:
- Connection Name: a relevant connection name
- Set Engine type to sqlserver-web
- Set Port to 14333
- Set Address as tds.cdata.com
- Set Username to a Connect AI user (e.g. [email protected])
- Set Password to the PAT for the above user
- Set Database name the Databricks connection (e.g., Databricks1)
π Create an RDS connection
- Click on "Create connection".
Integrating Databricks Data into Amazon SageMaker Canvas
With the connection to Connect AI configured in the RDS, you are ready to integrate live Databricks data into your Amazon SageMaker Canvas dataset.
- In the tabular dataset created in RDS with Databricks data, search for the Databricks connection configured on Connect AI in the search bar or from the list of connections.
π Search for the Databricks connection
- Select the table of your choice from Databricks, drag and drop it into the canvas on the right.
π Select a table of your choice
- You can create workflows by joining any number of tables from the Databricks connection (as shown below). Click on "Create dataset".
π Create the workflow and the dataset
- Once the dataset is created, click on "Select dataset" to build your model.
π Select the dataset to build a model
π Build a model from the dataset
- Perform analysis, generate prediction, and deploy the model.
At this point, you have access to live Databricks data in Amazon SageMaker that you can utilize to build custom ML models to generate predictive business insights and grow your organization.
SQL Access to Databricks Data from Cloud Applications
Now you have a direct connection to live Databricks data from Amazon SageMaker Canvas. You can create more connections, datasets, and predictive models to drive business β all without replicating Databricks data.
