Integrate Presto Data into Automated Tasks with Microsoft Flow

Use the CData Cloud Hub to create a virtual SQL Server database for Presto data and integrate live Presto data into your Microsoft Flow tasks.

Microsoft Flow is an online workflow service that automates events (known as workflows) across the most common apps and services. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to Presto data for visualizations, dashboards, and more. This article shows how to connect to the Cloud Hub from Microsoft Flow and integrate live Presto data into your workflows and tasks.

The CData Cloud Hub provides a pure SQL, cloud-to-cloud interface for Presto, allowing you to easily integrate with live Presto data in Microsoft Flow — without replicating the data. The CData Cloud Hub looks exactly like a SQL Server database to Microsoft Flow 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 Flow tasks, you need a new SQL Server connection:

  1. Log in to Microsoft Flow
  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

Integrating Presto Data into MS Flow Tasks

With the connection to the Cloud Hub configured, you are ready to integrate live Presto data into your Microsoft Flow tasks.

  1. Log in to Microsoft Flow
  2. Click My flows -> New and choose to create the flow from blank or template
  3. Add (or configure) a SQL Server action (like Get rows) and configure the action to connect to your Cloud Hub connection
  4. Select a Table to work with (from the drop-down menu) and configure any advanced options (like filters, orders, etc)
  5. Configure any actions to follow and test, then save the flow

SQL Access to Presto Data from Cloud Applications

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

To get SQL data access to 100+ SaaS, Big Data, and NoSQL sources directly from your cloud applications, see the CData Cloud Hub.
