Connect to Presto Data in DBVisualizer

Integrate Presto data with visual data analysis tools and data connection wizards in DBVisualizer

The CData JDBC Driver for Presto implements JDBC standards to provide connectivity to Presto data in applications ranging from business intelligence tools to IDEs. This article shows how to establish a connection to Presto data in DBVisualizer and use the table editor to edit and save Presto data.

Create a New JDBC Data Source for Presto Data

Follow the steps below to use the Driver Manager to provide connectivity to Presto data from DBVisualizer tools.

  1. In DBVisualizer, click Tools -> Driver Manager -> Create a New Driver.
  2. Enter a name for the data source.
  3. Enter the following in the URL Format box: jdbc:presto:
    The DBVisualizer Driver Manager.
  4. In the User Specified tab, click the Open File button and select the cdata.jdbc.presto.jar file, located in the lib subfolder of the installation directory.
  5. In the Driver Class menu, select the PrestoDriver class, cdata.jdbc.presto.PrestoDriver.

Define the Connection to the JDBC Data Source

Follow the steps below to save connection properties in the JDBC URL.

  1. In the Database tab, right-click the Database Connection node and click Create a Database Connection.
  2. In the Connection section, set the following options:

    • Database Type: If you selected the wizard option, the database type is automatically detected. If you selected the "No Wizard" option, select the Generic or Auto Detect option in the Database Type menu.
    • Driver: Select the driver you just created.
    • Database URL: Enter the full JDBC URL. The syntax of the JDBC URL is jdbc:presto: followed by the connection properties in a semicolon-separated list of name-value pairs.

      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.

      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 connection string is below:

      jdbc:presto:Server=127.0.0.1;Port=8080;
    • Database UserId: The username to use to authenticate to Presto.
    • Database Password: The password to use to authenticate to Presto.
  3. On the Connection tab, click Connect.

To browse through tables exposed by the Presto JDBC Driver, right-click a table and click Open in New Tab.

To execute SQL queries, use the SQL Commander tool: Click SQL Commander -> New SQL Commander. Select the Database Connection, Database, and Schema from the available menus.

See the "Supported SQL" chapter in the help documentation for more information on the supported SQL. See the "Data Model" chapter for table-specific information.
