  4. In the Data Sources and Drivers dialog, click the Add icon (The Add icon) and select Amazon Redshift.

  5. At the bottom of the data source settings area, click the Download missing driver files link. Alternatively, you can specify user drivers for the data source. For more information about user drivers, see Add a user driver to an existing connection.

  6. From the Connection type list, select URL only.

  7. Paste the JDBC URL from the Redshift cluster settings to the URL field in CLion.

  8. In User and Password fields, specify your Redshift credentials.
