How to connect to Redshift Data from IntelliJ

The CData JDBC Driver for Redshift enables you to access Redshift 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 Redshift data in IntelliJ.

Create a JBDC Data Source for Redshift

Follow the steps below to add the driver JAR and define connection properties required to connect to Redshift 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.redshift.jar, located in the installation directory.
   • JDBC Driver Class: In this menu, select cdata.jdbc.redshift.RedshiftDriver from the list.

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

     To connect to Redshift, set the following:

     • Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
     • Port: Set this to the port of the cluster.
     • Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
     • User: Set this to the username you want to use to authenticate to the Server.
     • Password: Set this to the password you want to use to authenticate to the Server.

     You can obtain the Server and Port values in the AWS Management Console:

     1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
     2. On the Clusters page, click the name of the cluster.
     3. On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Redshift JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.redshift.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     A typical JDBC URL is the following:

     jdbc:redshift:User=admin;Password=admin;Database=dev;Server=examplecluster.my.us-west-2.redshift.amazonaws.com;Port=5439;

Edit and Save Redshift 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.
