Integrate Live Cassandra 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 Cloud, you get instant, cloud-to-cloud access to Cassandra data from the apps you build using Power Apps. This article shows how to connect to Connect Cloud from Power Apps and build an app based on live Cassandra data.

CData Connect Cloud provides a pure SQL, cloud-to-cloud interface for Cassandra, allowing you to easily integrate with live Cassandra data in Power Apps — without replicating the data. CData Connect Cloud 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 Cassandra, leveraging server-side processing to quickly return Cassandra data.

Configure Cassandra Connectivity for Power Apps

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

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Cassandra" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Cassandra.

   Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Cassandra 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 Cassandra data from Power Apps.

Connecting to CData Connect Cloud

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

1. Log in to Power Apps
2. Click Dataverse -> Connections -> New connection
3. Select SQL Server
4. In the connection wizard:
   
   
   • Choose to connect directly
   • Set SQL server name to tds.cdata.com,14333
   • Set SQL database name to the name of the Cassandra connection (e.g. Cassandra1)
   • Set Username to a Connect Cloud user (e.g. user@mydomain.com)
   • Set Password to the PAT for the above user
   • Click Create

Building a Data-Centric App for Cassandra Data

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

1. Log in to Power Apps
2. Click Create and select "SQL"
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 Cassandra data that you can save and publish for use within your organization.

SQL Access to Cassandra Data from Cloud Applications

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