How to set Presto data as a JDBC data source in FineReport.

The CData JDBC Driver for Presto fully implements the JDBC standard and can provide Presto data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Presto data as JDBC data source in FineReport and view Presto data as a table in the Report Designer.

About Presto Data Integration

Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:

  • Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
  • Read and write access all of the data underlying your Trino or Presto instances
  • Optimized query generation for maximum throughput.

Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.

In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.


Getting Started


Set Up a JDBC Data Source of Presto Data

Follow the instruction below to set Presto data as a FineReport database connection.

  1. Copy the cdata.jdbc.presto.jar file from the lib folder in the CData JDBC Driver for Presto installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.presto.lic file as well.
  2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.
    3. 👁 FineReport Server Tab (Salesforce is shown.)

Next we will set up the data connection definition in the window.

  1. Database: Others
  2. JDBC Driver: cdata.jdbc.presto.PrestoDriver
  3. URL: A standard JDBC connection string using semicolon-separated connection properties.

    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.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Presto JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.presto.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)

    When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

    A typical JDBC URL is below:

     jdbc:presto:Server=127.0.0.1;Port=8080;
    4. 👁 FineReport data connection definition window (Salesforce is shown.)
  4. Click Connection pool attributes and set Test before getting connections to No.
    5. 👁 FineReport connection pool (Salesforce is shown.)

Click Test connection to ensure you have configured the connection properly. With the connection to Presto set up, you can use it as FineReport data source.

Select Presto Data in the Report Designer.

  1. Click to add a new template data set and select DB query to open the database query window.
    2. 👁 Adding a new DB query.
  2. Choose the JDBC connection that you created from the dropdown list.
  3. The Presto entities will appear as tables on the left pane.
  4. Write a SELECT statement for the Presto data tables and columns that you want to load.
    5. 👁 FineReport database query (Salesforce is shown.)
  5. Click preview and data is shown as table.
    6. 👁 FineReport database query preview (Salesforce is shown.)

With these simple steps, Presto can be used as a JDBC data source in FineReport.
