Query, Visualize, and Share live GraphQL Data in Redash

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

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

Configure GraphQL Connectivity for Redash

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

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

   You must specify the URL of the GraphQL service. The driver supports two types of authentication:

   • Basic: Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.
   • OAuth 1.0 & 2.0: Take a look at the OAuth section in the Help documentation for detailed instructions.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add GraphQL 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.

   • Server: enter the virtual SQL Server host name (tds.cdata.com)
   • User: 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 generated on the Settings page.
   • Port: enter 14333
6. Click Create.
7. Click Test Connection to ensure that the connection is configured properly.
