JDBC Driver for Presto

Build 20.0.7654

Establishing a Connection

Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Presto consists of three basic steps:

  • Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
  • Provide the driver class. For example:
    cdata.jdbc.presto.PrestoDriver
  • Provide the JDBC URL. For example:
    jdbc:presto:Server=127.0.0.1;Port=8080;
    
    or
    
    jdbc:cdata:presto:Server=127.0.0.1;Port=8080;

    The second format above can be used whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:presto:" or "jdbc:cdata:presto:" and can include any of the connection properties in name-value pairs separated with semicolons.

Connecting to Presto

Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

Securing Presto Connections

To enable TLS/SSL in the driver, set UseSSL to true.

Authenticating to Presto

Presto may be authenticated to by either LDAP or Kerberos. If the Presto server does not have authentication set up, leave AuthScheme set to NONE (default). In order to authenticate with either LDAP or Kerberos, follow the below steps:

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.
