Import Kafka Data into Microsoft Power Query
The CData API Server offers standards-based Web service endpoints that allow a variety of applications to access Kafka data. In this article, you will use the OData format to import Kafka data into Microsoft Power Query.
The CData API Server enables you to use REST, OData, JSON, or Open APIs to connect to and query Kafka data. The OData standard enables real-time access to the live data, and support for OData is integrated into PowerQuery. This article details how to import an OData feed of Kafka data into Microsoft Power Query.
Set Up the API Server
If you have not already done so, download the CData API Server. Once you have installed the API Server, follow the steps below to begin producing secure Kafka OData services:
Connect to Kafka
To work with Kafka data from Microsoft Power Query, we start by creating and configuring a Kafka connection. Follow the steps below to configure the API Server to connect to Kafka data:
- First, navigate to the Connections page.
-
Click Add Connection and then search for and select the Kafka connection.
-
Enter the necessary authentication properties to connect to Kafka.
- After configuring the connection, click Save & Test to confirm a successful connection.
Configure API Server Users
Next, create a user to access your Kafka data through the API Server. You can add and configure users on the Users page. Follow the steps below to configure and create a user:
- On the Users page, click Add User to open the Add User dialog.
-
Next, set the Role, Username, and Privileges properties and then click Add User.
-
An Authtoken is then generated for the user. You can find the Authtoken and other information for each user on the Users page:
Creating API Endpoints for Kafka
Having created a user, you are ready to create API endpoints for the Kafka tables:
-
First, navigate to the API page and then click
Add Table
.
-
Select the connection you wish to access and click Next.
-
With the connection selected, create endpoints by selecting each table and then clicking Confirm.
Gather the OData Url
Having configured a connection to Kafka data, created a user, and added resources to the API Server, you now have an easily accessible REST API based on the OData protocol for those resources. From the API page in API Server, you can view and copy the API Endpoints for the API:
Connect to Kafka Data from Power Query
-
In Microsoft Excel, open the Power Query Editor. From the Data ribbon, click Get Data -> Launch Power Query Editor:
-
Click New Source -> Other Sources -> OData feed:
-
In the OData feed connection, set the URL property to the OData Endpoint URL previously copied and click OK:
-
In the next step of the wizard, define the authentication credentials. Select Basic and then enter the credentials for a user authorized to make requests. Specify the User name and enter the user's authtoken in the Password field:
-
You can now access Kafka data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Transform Data to open the Query Editor. This will display the table data.
