Connect to Presto Data in NetBeans

The CData JDBC Driver for Presto integrates connectivity to live Presto data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to Presto data in NetBeans. You will create a connection and edit and save Presto data in the Table Editor.

Create a JDBC Data Source for Presto in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

• Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.presto.jar file. The driver JAR is located in the lib subfolder of the installation directory.
• Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.presto.PrestoDriver from the menu.
• Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

1. In the Service window, right-click the Database node and click New Connection.

2. In the New Connection Wizard, enter the following connection properties:

   • Driver Name: In the menu, select the CData JDBC Driver for Presto.
   • User Name: Enter the username. This can also be defined in the JDBC URL.
   • Password: Enter the password. This can also be defined in the JDBC URL.

   • JDBC URL: Specify the JDBC URL.

     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.

     A typical JDBC URL is the following:

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

Query Presto Data

To connect to Presto data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data. You can also insert, update, or delete records in the Data Views window.
