Set up a Connection

Prerequisites

The following are the prerequisites to establish a connection.

Service Account User Permissions

Important: It is recommended to use a separate service account to establish the connection to the data source, configured with the following minimum set of permissions.

Note:👨‍💻Who can provide these permissions? These permissions are typically granted by the Google Drive administrator, as users may not have the required access to assign them independently.

Operation	Objects	Access Permission
Validate	Connector Validation	drive.metadata.readonly
Crawling	Crawling	drive.metadata.readonly
Crawling & Profiling	Folders	drive.metadata.readonly
Crawling & Profiling	Files	drive.readonly

Connection Configuration Steps

Important: Users are required to have the Connector Creator role in order to configure a new connection.

Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for Google Drive, and complete the required parameters.

Note: Fields marked with an asterisk (*) are mandatory for establishing a connection.

Field Name	Description
Connector Type	By default, "Google Drive" is displayed as the selected connector type.
Connector Settings
Credential Manager*	Select the desired credentials manager from the drop-down list. Relevant parameters will be displayed based on the selected option. Supported Credential Managers: OE Credential Manager AWS Secrets Manager HashiCorp Azure Key Vault
Connector Environment	Select the environment (Example: PROD, STG) configured for the connector.
Connector Name*	Enter a unique name for the Google Drive connection. (Example: "GoogleDrivedb").
Connector Description	Enter a brief description of the connector.
Google Service Account*	Enter the Google Service Account.
File Path*	Enter the .p12 file path.

Default Governance Roles
Default Governance Roles*	Select the appropriate users or teams for each governance role from the drop-down list. All users configured in the security settings are available for selection.
Admin Roles
Admin Roles*	Select one or more users from the dropdown list for Integration Admin and Security & Governance Admin. All users configured in the security settings are available for selection.
No of Archive Objects
No Of Archive Objects*	This shows the number of recent metadata changes to a dataset at the source. By default, it is off. To enable it, toggle the Archive button and specify the number of objects to archive. Example: Setting it to 4 retrieves the last four changes, displayed in the 'Version' column of the 'Metadata Changes' module.
Bridge
Select Bridge*	If applicable, select the bridge from the drop-down list. The drop-down list displays all active bridges that have been configured. These bridges facilitate communication between data sources and the system without requiring changes to firewall rules.

After entering all connection details, the following actions can be performed:

- Click Validate to verify the connection.
- Click Save to store the connection for future use.
- Click Save & Configure to apply additional settings before saving.
The saved connection will appear on the Connectors home page.

Manage Connector Operations

Crawl

Important: To perform crawl operations, users must be assigned the Integration Admin role.

Navigate to the Connectors page and click Crawl/Profile.
This action initiates the metadata collection process from the data source and loads it into the File Manager.

The files/folders will be added to the Data Catalog.

Note: Column-level details are not populated in the Data Catalog for the Google Drive connector. Only file and folder-level metadata is captured.

Managing connectors includes:

Connectors Health: Displays the current status of each connector using a green icon for active connections and a red icon for inactive connections, helping to monitor the connectivity with data sources.
Viewing: Click the Eye icon next to the connector name to view connector details, including databases, tables, columns, and codes.
