Integrate connectivity to Presto data with wizards in 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.
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.
- In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
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.
