Integrate Live Presto Data into Custom Business Apps Built in PowerApps

Use the CData Cloud Hub to create a virtual SQL Server Database for Presto data and integrate live Presto 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 Presto 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 Presto data.

The CData Cloud Hub provides a pure SQL, cloud-to-cloud interface for Presto, allowing you to easily integrate with live Presto 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 Presto, leveraging server-side processing to quickly return Presto data.

Create a Virtual SQL Database for Presto 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 "Presto" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Presto.

    Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

    To enable TLS/SSL, set UseSSL to true.

    Authenticating with LDAP

    In order to authenticate with LDAP, set the following connection properties:

    • AuthScheme: Set this to LDAP.
    • User: The username being authenticated with in LDAP.
    • Password: The password associated with the User you are authenticating against LDAP with.

    Authenticating with Kerberos

    In order to authenticate with KERBEROS, set the following connection properties:

    • AuthScheme: Set this to KERBEROS.
    • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
    • KerberosRealm: The Kerberos Realm used to authenticate the user with.
    • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.
  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 Presto 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 Presto database you created earlier (like prestodb)
    • Set the Username and Password and click Create

Building a Data-Centric App for Presto Data

With the connection to the Cloud Hub configured, you are ready to integrate live Presto 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 Presto data that you can save and publish for use within your organization.

SQL Access to Presto Data from Cloud Applications

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