By default, the selected connection type is displayed as the Azure Data Lake. 

Credential Manager

Select the option from the drop-down menu, where you want to save your credentials:

OE Credential Manager: Azure Data Lake connection is configured with the basic Username and Password of the service account in real-time when OvalEdge establishes a connection to the Azure Data Lake database. Users need to add the credentials manually if the OE Credential Manager option is selected.

HashiCorp: The credentials are stored in the HashiCorp database server and fetched from HashiCorp to OvalEdge.  

AWS Secrets Manager: The credentials are stored in the AWS Secrets Manager database server and fetched from the AWS Secrets Manager to OvalEdge.

License Add Ons

All the connectors will have a Base Connector License by default that allows you to crawl and profile to obtain the metadata and statistical information from a datasource. 

OvalEdge supports various License Add-Ons based on the connector’s functionality requirements.

• Select the Auto Lineage Add-On license that enables the automatic construction of the Lineage of data objects for a connector with the Lineage feature. 
• Select the Data Quality Add-On license to identify, report, and resolve the data quality issues for a connector whose data supports data quality, using DQ Rules/functions, Anomaly detection, Reports, and more.
• Select the Data Access Add-On license that will enforce connector access via OvalEdge with Remote Data Access Management (RDAM) feature-enabled.

Connector Environment

The environment drop-down menu allows you to select the environment configured for the connector from the drop-down list. For example, PROD, or STG (based on the configured items in the OvalEdge configuration for the connector.environment).

The purpose of the environment field is to help you identify which connector is connecting what type of system environment (Production, STG, or QA).

Note: The steps to set up environment variables are explained in the prerequisite section.
