Create Apps from Presto Data in Qlik Sense Cloud



Use CData Connect Cloud to connect to Presto Data and build apps from live Presto data in Qlik Sense Cloud.

Qlik Sense Cloud allows you to create and share data visualizations and interact with information in new ways. CData Connect Cloud creates a live connection to Presto. By pairing Qlik Sense Cloud with CData Connect Cloud, you get true cloud-to-cloud connectivity to all of your SaaS and cloud-based Big Data and NoSQL sources — no need to migrate your data or write your integrations. Simply connect to Connect Cloud from Qlik Sense Cloud and get instant, live access to your Presto data.

In this article, we walk through two connections:

  1. Connecting to Presto in Connect Cloud
  2. Connecting to Connect Cloud from Qlik Sense Cloud to create a model and build a simple dashboard

Configure Presto Connectivity for Qlik Cloud

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

(Optional) Add a New Connect Cloud User

As needed, create Users to connect to Presto through Connect Cloud.

  1. Navigate to the Users page and click Invite Users
  2. Enter the new user's email address and click Send to invite the user
  3. You can review and edit users from the Users page

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 to the CData Connect Cloud OData service. 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.

Connect to Presto from Connect Cloud

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

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Presto" from the Add Connection panel
  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 Create & Test
  5. Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.

With the connection to Presto configured, you are ready to connect to Presto data from Qlik Sense Cloud.

Create a Qlik Sense App from Presto Data

This section walks through adding Presto data to a Qlik Sense app for visualizations, analytics, reporting, and more.

Create a New App and Upload Data

  2. Name and configure the new app and click "Create"
  3. In the workspace, click to open the new app
  4. Click to add data from files and other sources
  5. Select the Microsoft SQL Server connector and set the configuration properties.
    • Set Server to tds.cdata.com
    • Set Port to 14333
    • Set Database to the connection you created (e.g. Presto1)
    • Set User name to the Connect Cloud user (e.g. [email protected])
    • Set Password to the PAT for the above user
  6. Select an owner for the connection
  7. Select a Presto entity (Table) to view
  8. Click Next, configure the model, and load the data into Qlik Sense.
