How to integrate Metabase with Cosmos DB 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 Cosmos DB data. This article describes how to connect to Cosmos DB and build a simple visualization using Cosmos DB data.

CData Connect provides a pure cloud-to-cloud interface for Cosmos DB, allowing you to easily integrate with live Cosmos DB 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 Cosmos DB, leveraging server-side processing to quickly return Cosmos DB data.

Configure Cosmos DB Connectivity for Metabase

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

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

   To obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

   • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
   • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Cosmos DB 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 Cosmos DB 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. "Cosmos DB (Connect Cloud)")
   • Host: tds.cdata.com
   • Port: 14333
   • Database name: The name of the connection you just created (e.g. CosmosDB1)
   • 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 Cosmos DB Data with Metabase

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

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

   SELECT City, CompanyName FROM Customers

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