Integrate Live Kafka Data into Custom Business Apps Built in Power Apps

Power Apps is a service for building and using custom business apps that connect to your data and work across the web and mobile — without the time and expense of custom software development. When paired with CData Connect Server, you get instant access to Kafka data from the apps you build using Power Apps. This article shows how to connect to Connect Server from Power Apps and build an app based on live Kafka data.

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

Create a Virtual SQL Database for Kafka Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "Kafka" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Kafka.

   Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.

   Authorization Mechanisms

   • SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
   • SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
   • SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
   • Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.

   You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connecting to CData Connect Server

To use Connect Server to integrate Kafka data into your Power Apps, you need a new SQL Server connection:

1. Log in to Power Apps
2. Click Data -> Connections -> New connection
3. Select SQL Server
4. In the connection wizard:
   
   
   • Choose to connect directly
   • Set SQL server name to the address of your Connect Server instance (CONNECT_SERVER_URL)
   • Set SQL database name to the name of the virtual Kafka database you created earlier (like kafkadb)
   • Set the Username and Password and click Create

Building a Data-Centric App for Kafka Data

With the connection to Connect Server configured, you are ready to integrate live Kafka data into the apps you build in Power Apps.

1. Log in to Power Apps
2. Click Create, hover over "Start from data" and click Make this app
3. Select the SQL Server connection you created
4. Search for or choose a table to work with
5. Click Connect
6. Customize the newly created app just like you would any other, including changing the layout and setting the fields exposed in BrowseScreen, DetailScreen, and EditScreen

At this point, you have an app with read and write access to live Kafka data that you can save and publish for use within your organization.

SQL Access to Kafka Data from Applications

Now you have a direct connection to live Kafka data from Microsoft Power Apps. You can create more connections and apps to drive business — all without replicating Kafka data.
