Build Amazon DynamoDB Visualizations in Tableau Online

Use the CData Cloud Hub to create a virtual MySQL Database for Amazon DynamoDB 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 Amazon DynamoDB data for visualizations, dashboards, and more. This article shows how to use a MySQL client to create a virtual database for Amazon DynamoDB and build visualizations from Amazon DynamoDB data in Tableau Online.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Amazon DynamoDB, allowing you to easily build visualizations from live Amazon DynamoDB 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 Amazon DynamoDB, leveraging server-side processing to quickly return Amazon DynamoDB data.

Create a Virtual MySQL Database for Amazon DynamoDB 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 "Amazon DynamoDB" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Amazon DynamoDB.

    The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

  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 Amazon DynamoDB Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Amazon DynamoDB 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 Amazon DynamoDB Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Amazon DynamoDB 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.
