Work with Live Redshift Data in Power Query

Power Query is a data transformation and data preparation engine. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Redshift data from Power Query. This article shows how to connect to Connect Cloud from Power Query through Microsoft Excel and get live access to Redshift data for transformation and preparation.

CData Connect Cloud provides a pure SQL, cloud-to-cloud interface for Redshift, allowing you to easily integrate with live Redshift data in Power Query — without replicating the data. CData Connect Cloud looks exactly like a SQL Server database to Power Query and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Redshift, leveraging server-side processing to quickly return Redshift data.

Configure Redshift Connectivity for Power Query

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

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Redshift" from the Add Connection panel
3. 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:

   1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
   2. On the Clusters page, click the name of the cluster.
   3. On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.
4. Click Create & Test
5. 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.

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 Redshift data from Power Query.

Working with Live Redshift Data in Power Query

With the connection to Connect Cloud configured, you are ready to work with live Redshift data in Power Query.

1. In Microsoft Excel, open the Power Query Editor (from the Data ribbon, click Get Data -> Launch Power Query Editor)
2. Click New Source -> SQL Server
3. In the SQL Server database modal:
   • Set Server to tds.cdata.com,14333
   • (Optional) Set Database to the name of the Redshift connection (e.g. Redshift1 )
4. In the SQL Server credentials modal, select "Database" and
   • Set User to your Connect Cloud username (e.g. user@mydomain.com )
   • Set Password to the PAT for the above user
5. Click Connect
6. Select the table(s) you wish to work with in the Navigator and click "OK"

At this point, you have live access to Redshift data from Power Query for transformation and preparation.
