Use the API Server and Redshift ADO.NET Provider to Access Redshift Data in Microsoft PowerPivot



Use the API Server to connect to live Redshift data in the PowerPivot business intelligence tool.

This article will explain how to use the API Server and the ADO.NET Provider for Redshift (or any of 200+ other ADO.NET Providers) to provide Redshift data as OData services and then consume the data in Microsoft Excel's PowerPivot business intelligence tool. Follow the steps below to retrieve and edit Redshift data in Power Pivot.

Set Up the API Server

Follow the steps below to begin producing secure Redshift OData services:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to Redshift

After you deploy the API Server and the ADO.NET Provider for Redshift, provide authentication values and other connection properties needed to connect to Redshift by clicking Settings -> Connections and adding a new connection in the API Server administration console.

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.

You can then choose the Redshift entities you want to allow the API Server access to by clicking Settings -> Resources.

Additionally, click Settings -> Server and set the Default Format to XML (Atom) for compatibility with Excel.

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.

Import Redshift Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

  1. In Excel, click the PowerPivot Window icon in the PowerPivot tab to open PowerPivot.
  2. Click Home -> Get External Data -> From Data Service -> From OData Data Feed.
  3. Add authentication parameters. Click Advanced and set the Integrated Security option to Basic. You will need to enter the User Id and Password of a user who has access to the CData API Server. Set the password to the user's authtoken.

  4. In the Base URL box, enter the OData URL of the CData API Server. For example, http://localhost:8032/api.rsc.

  5. Select which tables you want to import and click Finish.

  6. You can now work with Redshift data in Power Pivot.
