Connecting to KingbaseES

Connection Steps

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

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

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

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

   Connection Configuration Information

   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 value in the URL will take precedence.
   Port	The port of the database. If the URL field is filled in, the value in the URL will take 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.
   ssl	Whether to use an SSL connection.
   sslmode	Fill in according to the data source configuration, such as "disable", "allow", "prefer", "require", "verify-ca", "verify-full"
   Prefer using database comment as dataset title	Whether to display the table name or the table comment as the title. When enabled, the title is shown; when disabled, the table comment is shown.
   URL	The JDBC URL of the database.
   Transaction Isolation Level for Read	The transaction isolation level for read operations. This setting only affects reading data; writing data still uses the default isolation level.
   Hierarchical loading of schema and tables	Disabled by default. When enabled, schema and tables are loaded hierarchically. Only the schema is loaded during connection; you need to click the schema to load the tables under it.
   Query Timeout (seconds)	Default is 600. When the data volume is large, you can appropriately increase the timeout.
   Show only tables under the specified database/schema	When this option is selected and the database field is not empty, only the tables under that 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 KingbaseES connection.

Please note

1. Parameters marked with * are required; other parameters are optional.
2. You must execute the preset code when connecting to the data source. 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.
