How to integrate Metabase with Snowflake Data

Metabase is an open source data visualization tool that allows users to create interactive dashboards. When paired with CData Connect Cloud, users can easily create visualizations and dashboards linked to live Snowflake data. This article describes how to connect to Snowflake and build a simple visualization using Snowflake data.

CData Connect provides a pure cloud-to-cloud interface for Snowflake, allowing you to easily integrate with live Snowflake data in Metabase — without replicating the data. Connect looks exactly like a SQL Server database to Metabase and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Snowflake, leveraging server-side processing to quickly return Snowflake data.

Configure Snowflake Connectivity for Metabase

Connectivity to Snowflake from Metabase is made possible through CData Connect Cloud. To work with Snowflake data from Metabase, we start by creating and configuring a Snowflake connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Snowflake" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Snowflake.

   To connect to Snowflake:

   1. Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
   2. Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
   3. Set Warehouse to the Snowflake warehouse.
   4. (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
   5. (Optional) Set Database and Schema to restrict the tables and views exposed.

   See the Getting Started guide in the CData driver documentation for more information.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Snowflake Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. 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, you are ready to connect to Snowflake data from Metabase.

Connect to CData Connect from Metabase

After creating the virtual database, navigate to your Metabase instance. Use the SQL Server interface to connect to Connect Cloud.

1. Navigate to the administration screen (Settings -> Admin) and click "Add Database" from the "Databases" tab
2. Configure the connection to Connect Cloud and click "Save"
   • Database type: Select "SQL Server"
   • Name: Name the connection (e.g. "Snowflake (Connect Cloud)")
   • Host: tds.cdata.com
   • Port: 14333
   • Database name: The name of the connection you just created (e.g. Snowflake1)
   • Username: A Connect Cloud username (e.g. user@mydomain.com)
   • Password: The PAT for the above Connect Cloud user
   • Click to Use a secure connection (SSL)

Execute Snowflake Data with Metabase

Once you configure the connection to Connect Cloud, you can query Snowflake and build visualizations.

1. Use the "Write SQL" tool to retrieve the Snowflake data
2. Write a SQL query based on the Snowflake connection in CData Connect Cloud, e.g.
   
   

   SELECT Id, ProductName FROM Products

3. Navigate to the "Visualization" screen, choose a visualization, and configure the visualization
