Connection Steps

Please follow the steps below to connect to the Vertica data source.

1. Click "New Data Connection" in the upper right corner of the data connection page.

2. Select the Vertica data source from the data source types.

3. Fill in the required parameters for the data source connection as prompted.

   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, the URL takes precedence.

   Username	The username for the database.
   Password	The password for the database.
   Database	The name of the database.
   Schema	The schema of the database.
   Max Connections	The maximum number of connections in the connection pool.
   Encoding	The encoding setting for the database connection.
   Prefer using database comment as dataset title	Whether to display the table name or the table comment as the title.
   Hadoop Authentication Method	Hadoop authentication method. "simple" is simple authentication and requires no extra information; "Kerberos" requires additional information.
   realmA	Required when Hadoop authentication is set to Kerberos.
   kdcA	Required when Hadoop authentication is set to Kerberos.
   realmB	Required when Hadoop authentication is set to Kerberos.
   kdcB	Required when Hadoop authentication is set to Kerberos.
   server principal	Required when Hadoop authentication is set to Kerberos.
   URL	The JDBC URL of the database.
   Transaction Isolation Level for Read Operations	This setting only affects data reading; data writing still uses the default isolation level.
   Hierarchical loading of schema and tables	Default is Off. When enabled, schema and tables are loaded hierarchically. Only the schema is loaded during connection, and you need to click the schema to load the tables under it.
   Query Timeout (seconds)	Default is 600. For large data volumes, you can increase the timeout as needed.
   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 database will be displayed.

4. After filling in the parameters, click the Validate button to get the validation result (this checks 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 Vertica connection.

Please note

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.
