Use CData Connect Cloud to create a virtual MySQL Database for Cosmos DB data and build visualizations in Tableau Online.

Tableau Online is an analytics platform fully hosted in the cloud. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Cosmos DB data for visualizations, dashboards, and more. This article shows how to create a virtual database for Cosmos DB and build visualizations from Cosmos DB data in Tableau Online.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Cosmos DB, allowing you to easily build visualizations from live Cosmos DB data in Tableau Online without installing connectors or publishing worksheets and data sources from Tableau Desktop. As you build visualizations, Tableau Online generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Cosmos DB, leveraging server-side processing to quickly return Cosmos DB data.

Create a Virtual MySQL Database for Cosmos DB Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Cloud and click Databases.
  2. Select "Cosmos DB" from Available Data Sources.
  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 Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to build visualizations in Tableau Online.

Visualize Live Cosmos DB Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Cosmos DB database in Connect Cloud and building a simple visualization from the data.

  1. Log into Tableau Online, select a project, and create a new workbook.
  2. In the new workbook, choose the MySQL Connector from the data wizard and fill in the values for your Connect Cloud instance.
  3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINed tables as needed).
  4. Select Dimensions and Measures and configure your visualization.

SQL Access to Cosmos DB Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Cosmos DB data from your Tableau Online workbook. You can create new visualizations, build dashboards, and more, with no need to publish data sources and workbooks from Tableau Desktop.
