Integrate Live Cassandra Data into Custom Business Apps Built in PowerApps

Use the CData Cloud Hub to create a virtual SQL Server Database for Cassandra data and integrate live Cassandra data into apps built in Microsoft PowerApps.

PowerApps 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 the CData Cloud Hub, you get instant, cloud-to-cloud access to Cassandra data from the apps you build using PowerApps. This article shows how to connect the Cloud Hub from PowerApps and build an app based on live Cassandra data.

The CData Cloud Hub provides a pure SQL, cloud-to-cloud interface for Cassandra, allowing you to easily integrate with live Cassandra data in PowerApps — without replicating the data. The CData Cloud Hub looks exactly like a SQL Server database to PowerApps 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.

Create a Virtual SQL Database for Cassandra Data

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

  1. Login to Cloud Hub and click Databases.
  2. Select "Cassandra" from Available Data Sources.
  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 Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connecting to the CData Cloud Hub

To use the Cloud Hub to integrate Cassandra data into your PowerApps, you need a new SQL Server connection:

  1. Log in to PowerApps
  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 Cloud Hub instance (myinstance.cdatacloud.net)
    • Set SQL database name to the name of the virtual Cassandra database you created earlier (like cassandradb)
    • Set the Username and Password and click Create

Building a Data-Centric App for Cassandra Data

With the connection to the Cloud Hub configured, you are ready to integrate live Cassandra data into the apps you build in PowerApps.

  1. Log in to PowerApps
  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 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 PowerApps. You can create more connections and apps to drive business — all without replicating Cassandra data.
