Build Avro Visualizations in Tableau Cloud



Use CData Connect Server to create a virtual SQL Server Database for Avro data and build visualizations in Tableau Cloud.

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

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

Create a Virtual SQL Server Database for Avro Data

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

  1. Login to Connect Server and click Connections.
  2. Select "Avro" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Avro. Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.
  4. Click Save Changes
  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 Cloud.

Visualize Live Avro Data in Tableau Cloud

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

  1. Log into Tableau Cloud, select a project, and create a new workbook.
  2. In the new workbook, choose the Microsoft SQL Server Connector from the data wizard and fill in the values for your Connect Server instance.
    NOTE: Be sure to check the "Require SSL" checkbox.
  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 Avro Data from Applications

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