Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application, based on CData JDBC Driver for Presto.

Follow these steps:

1. Add the driver JAR file to the classpath. The JAR file is located in the installation directory's lib subfolder. Ensure that the .lic file is located in the same folder as the JAR file.
2. Provide the driver class. For example:
   

   cdata.jdbc.presto.PrestoDriver

3. Provide the JDBC URL. For example:
   

   jdbc:presto:Server=127.0.0.1;Port=8080;

   Or, if there is a conflict in your application between drivers using the same URL format, use this form to ensure that you are using the CData driver:
   

   jdbc:cdata:presto:Server=127.0.0.1;Port=8080;

   Ensure that the URL starts with either jdbc:presto: or jdbc:cdata:presto:. The URL 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 supports authentication via either LDAP or Kerberos. If the Presto server does not have authentication set up, leave AuthScheme set to NONE (default).

The following subsections describe the requirements for authenticating with either LDAP or Kerberos.

LDAP

To authenticate with LDAP, set these connection properties:

• AuthScheme: LDAP.
• User: The authenticating user.
• Password: The authenticating user's password.

Kerberos

For details on authenticating with Kerberos, see Using Kerberos.
