Use CData Connect Cloud to connect to live Azure Synapse data in Redash for querying, visualizing, and sharing.
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 Azure Synapse data. This article demonstrates how to connect to Azure Synapse using Connect Cloud and work with live Azure Synapse data in Redash.
CData Connect Cloud provides a pure SQL Server interface for Azure Synapse, allowing you to query data from Azure Synapse 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 Azure Synapse, leveraging server-side processing to return the requested Azure Synapse data quickly.
Configure Azure Synapse Connectivity for Redash
Connectivity to Azure Synapse from Redash is made possible through CData Connect Cloud. To work with Azure Synapse data in Redash, we start by creating and configuring a Azure Synapse connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "Azure Synapse" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Azure Synapse.
Connecting to Azure Synapse
In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:
- Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
- Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.
Authenticating to Azure Synapse
Connect to Azure Synapse using the following properties:
- User: The username provided for authentication with Azure.
- Password: The password associated with the authenticating user.
- Click Create & Test
- Navigate to the Permissions tab in the Add Azure Synapse 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.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
