Query, Visualize, and Share live Cloudant Data in Redash

Redash is a collaboration tool that lets you query, visualize, and share your data. When paired with CData Connect AI, Redash gets access to live Cloudant data. This article demonstrates how to connect to Cloudant using Connect AI and work with live Cloudant data in Redash.

CData Connect AI provides a pure SQL Server interface for Cloudant, allowing you to query data from Cloudant without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to Cloudant, leveraging server-side processing to return the requested Cloudant data quickly.

Configure Cloudant Connectivity for Redash

Connectivity to Cloudant from Redash is made possible through CData Connect AI. To work with Cloudant data in Redash, we start by creating and configuring a Cloudant connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Cloudant" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Cloudant.

   Set the following connection properties to connect to Cloudant:

   • User: Set this to your username.
   • Password: Set this to your password.
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Cloudant Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the 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 and a PAT generated, you are ready to connect to Cloudant data from Redash.
