Set up a Connection

Prerequisites

The following are the prerequisites to establish a connection.

Ensure that the CSV files follow the required formatting standards for proper data processing and visibility. Refer to CSV Format Requirements.

Service Account User Permissions

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.

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

Objects	Access Permission
Connector Validation	Execute permission (x), Files: Read permission (r)
Crawling	Execute permission (x), Files: Read permission (r)
Folder	Execute permission (x), Files: Read permission (r)
Files	Execute permission (x), Files: Read permission (r)

Connection Configuration Steps

Users are required to have the Connector Creator role in order to configure a new

connection.

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

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

Field Name	Description
Connector Type	By default, "DSEFS" is displayed as the selected connector type.
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 DSEFS connection (Example: "DSEFSdb").
Connector Description	Enter a brief description of the connector.
Username*	Enter the valid username with access privileges to the Datastax Enterprise File System.
Password*	Enter the password for the provided username to authenticate access.
DSEFS URL*	Enter the complete and valid URL of the Datastax Enterprise File System instance (Example: https://xxxxxx.xxx).
Proxy Enabled*	Select Yes to route the connection through a configured proxy, or No to connect directly without a proxy.

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*

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.
