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 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.
