Connecting to MongoDB

Connection Steps

Please follow the steps below to connect to a MongoDB data source.

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

2. Select the MongoDB data source from the list of 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.
   Port	The port 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.
   Max Connections	The maximum number of connections in the connection pool.
   Authentication Database	The database where the user for connection is created.
   Prefer using table comment as dataset title	Whether to display the table name or the table comment as the title.

   Query Timeout (seconds)	Default is 600. For large data volumes, you can increase the timeout.
   Show only tables under specified database/schema	If selected and the database field is not empty, only tables under that DB are shown.

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 MongoDB 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.
