After Installing the Connector you can connect and create a Data Source for data in Presto.

Setting Up a Data Source

Complete the following steps to connect to the data:

1. Under Connect | To a Server, click More....
2. Select the data source called Presto by CData.
3. Enter the information required for the connection.
4. Click Sign In.
5. If necessary, select a Database and Schema to discover what tables and views are available.

Using the Connection Builder

The connector makes the most common connection properties available directly in Tableau. However, it can be difficult to use if you need to use more advanced settings or need to troubleshoot connection issues. The connector includes a separate connection builder that allows you to create and test connections outside of Tableau.

There are two ways to access the connection builder:

• On Windows, use a shortcut called Connection Builder in the Start menu, under the CData Tableau Connector for Presto folder.
• You can also start the connection builder by going to the driver install directory and running the .jar file in the lib directory.

In the connection builder, you can set values for connection properties and click Test Connection to validate that they work. You can also use the Copy to Clipboard button to save the connection string. This connection string can be given to the Connection String option included in the connector connection window in Tableau.

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 connector, 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.
