Integrate with Presto Data in SnapLogic



Use CData Connect Cloud to connect to and integrate with live Presto data in SnapLogic.

SnapLogic's iPaaS platform helps organizations automate application, data and cloud integrations. When paired with CData Connect Cloud, SnapLogic gets access to live Presto data. This article demonstrates how to connect to Presto using Connect Cloud and integrate with Presto data in SnapLogic.

CData Connect Cloud provides a pure SQL Server interface for Presto, allowing you to query data from Presto without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Presto, leveraging server-side processing to return the requested Presto data quickly.

Configure Presto Connectivity for SnapLogic

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

  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.

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.

Connect to Presto from SnapLogic using Connect Cloud

To establish a connection from SnapLogic to CData Connect Cloud, you will need to download the JDBC Driver.

  1. Open the Client Tools page of CData Connect Cloud.
  2. In the Dev Tools section, click JDBC.
  3. Download and run the setup file.
  4. When the installation is complete, locate the JDBC Connect JAR file in the JDBC driver's installation directory, for example, C:\Program Files\CData\JDBC Driver for CData Connect\lib.
  5. Copy the JDBC Connect JAR file (cdata.jdbc.connect.jar).

After copying the JDBC CData Connect JAR file, you will need to paste it into the SnapLogic installation location and configure the connection to Connect Cloud.

  1. Log into SnapLogic.
  2. Click the Managers tab.
  3. Select a folder from the Project Spaces to add the JDBC JAR file to.
  4. Click the Files tab.
  5. Click the button in the top right to upload the CData Connect Cloud JDBC JAR file. It appears as a file once uploaded.
  6. Click the Designer tab.
  7. Click JDBC to expand the options for "snaps."
  8. Click and drag a Generic JDBC - Select "snap" onto the designer.
  9. Click Add Account > Continue.
  10. Enter the JDBC connection properties.
    • JDBC driver: add the CData Connect Cloud JAR file
    • JDBC driver Class: enter cdata.jdbc.connect.ConnectDriver
    • JDBC Url: enter a JDBC connection string for the JDBC driver. For example: jdbc:connect:AuthScheme=Basic;User={username};Password={PAT};
    • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
    • Password: enter the PAT you generated on the Settings page.
  11. Click Validate. If the connection succeeds, the "snap" is ready to use.
  12. Click Apply.

You can now create reports with the connected data.
