Build CockroachDB Visualizations in Tableau Cloud

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

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

Configure CockroachDB Connectivity for Tableau Online

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

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

   Set the following to connect to CockroachDB.

   • Server: The host name or IP address of the server.
   • Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
   • Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
   • User: The Cockroach DB user account used to authenticate.
   • Password: The password used to authenticate the user.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add CockroachDB 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 CockroachDB data from Tableau Cloud.

Visualize Live CockroachDB Data in Tableau Cloud

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

1. Log into Tableau Cloud, select a account, 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 Cloud instance.
   • Set Server to tds.cdata.com,14333
   • Set Database to the CockroachDB connection you created (e.g. CockroachDB1)
   • Set Username to your Connect Cloud username (e.g. user@mydomain.com)
   • Set Password to a PAT for the above user
   • Check the Require SSL checkbox
3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINad tables as needed).
4. Select Dimensions and Measures and configure your visualization.

Real-Time Access to CockroachDB Data from Cloud Applications

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