Build CockroachDB Visualizations in Tableau Desktop

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. 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.

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 without installing connectors. As you build visualizations, Tableau 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

Connectivity to CockroachDB from Tableau is made possible through CData Connect Cloud. To work with CockroachDB data from Tableau, 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.

Visualize Live CockroachDB Data in Tableau

To establish a connection from Tableau Desktop to the CData Connect Cloud Virtual SQL Server API, follow these steps.

1. In Tableau Desktop, open a new book. Under To a Server, select More, then Microsoft SQL Server.
2. Enter your credentials:
   • Server: enter the Virtual SQL Server endpoint and port separated by a comma: tds.cdata.com,14333
   • Database: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, CockroachDB1).
   • Authentication: select Use a specific username and password.
   • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
   • Password: enter the PAT you previously generated.
   • Require SSL: leave this selected.
3. Click Sign In.
4. Select the Database (Connect Cloud connection) you wish to work with and opt for a Live or Extract Connection type.
5. Select the table(s) you wish to visualize. If you select multiple tables, define the relationship between the tables using the appropriate columns.
6. Select the fields to visualize.
