Use CData Connect Cloud to connect to live Redshift 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 Redshift data. This article demonstrates how to connect to Redshift using Connect Cloud and work with live Redshift data in Redash.
CData Connect Cloud provides a pure SQL Server interface for Redshift, allowing you to query data from Redshift 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 Redshift, leveraging server-side processing to return the requested Redshift data quickly.
Configure Redshift Connectivity for Redash
Connectivity to Redshift from Redash is made possible through CData Connect Cloud. To work with Redshift data in Redash, we start by creating and configuring a Redshift connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "Redshift" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Redshift.
To connect to Redshift, set the following:
- Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
- Port: Set this to the port of the cluster.
- Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
- User: Set this to the username you want to use to authenticate to the Server.
- Password: Set this to the password you want to use to authenticate to the Server.
You can obtain the Server and Port values in the AWS Management Console:
- Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
- On the Clusters page, click the name of the cluster.
- On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.
- Click Create & Test
- Navigate to the Permissions tab in the Add Redshift 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.
