How to connect to Presto Data from IntelliJ

The CData JDBC Driver for Presto enables you to access Presto as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Presto data in IntelliJ.

Getting Started

---

Create a JBDC Data Source for Presto

Follow the steps below to add the driver JAR and define connection properties required to connect to Presto data.

1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.

2. In the Data Source Properties dialog that appears, the following properties are required:

   • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.presto.jar, located in the installation directory.
   • JDBC Driver Class: In this menu, select cdata.jdbc.presto.PrestoDriver from the list.

   • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:presto: and includes connection properties separated with semicolons.

     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;

Edit and Save Presto Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
