6. Click the Add button to add the Kylin connection.

1. Parameters marked with * are required; others are optional.
2. When connecting to a data source, you must execute the preset code. Failure to do so may result in certain functions being unavailable during data analysis. In addition, when upgrading from a version prior to 4.4 to 4.4, you need to execute the preset code for existing data connections in the system.
