Build Azure Table Visualizations in Tableau Online

Use the CData Cloud Hub to create a virtual MySQL Database for Azure Table data and build visualizations in Tableau Online.

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Azure Table, allowing you to easily build visualizations from live Azure Table 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, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Azure Table, leveraging server-side processing to quickly return Azure Table data.

Create a Virtual MySQL Database for Azure Table Data

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

  1. Login to Cloud Hub and click Databases.
  2. Select "Azure Table" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Azure Table.

    Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

  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 Azure Table Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Azure Table database in Cloud Hub 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 Cloud Hub 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 Azure Table Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Azure Table 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.
