   **Connection Configuration Information Description**

   | Field                                 | Description                                                  |
   | -------------------------------------- | ------------------------------------------------------------ |
   | Name                                  | The name of the connection. Required and unique within the user. |
   | Host Address                          | The address of the database. If the URL field is filled in, the URL will take precedence. |
   | Port                                  | The port of the database. If the URL field is filled in, the URL will take precedence. |
   | Max Connections                       | Maximum number of connections in the connection pool.        |
   | Prefer to use database comment as dataset title | Choose whether to display the table name or the table comment as the title. When enabled, the title is displayed; when disabled, the table comment is displayed. |
   | URL                                   |                                                              |
   | zkRoot                                |                                                              |
   | Query Timeout (seconds)               | Default is 600. If the data volume is large, you can increase the timeout appropriately. |
   | Only show tables under the specified database/schema | When this option is selected and the database field is not empty, only tables under the specified db will be displayed. |

4. After filling in the parameters, click the `Validate` button to get the validation result (this validates the connectivity between HENGSHI SENSE and the configured data connection; you cannot add the connection if validation fails).

5. After validation passes, click `Execute Preset Code` to pop up the preset code for this data source, then click the execute button.

6. Click the `Add` button to add the `Hbase` connection.

> \[!CAUTION] Please Note
>
> 1. Parameters marked with \* are required; other parameters 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.
