Set up a Connection

Prerequisites

The following are the prerequisites to establish a connection.

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 Sigma Computing administrator, as users may not have the required access to assign them independently.

Objects	Access Permission
Connector Validation	Read only
Crawling	Read only
Lineage	Read only
Delta Crawl	Read only
Workbooks	Read only
Pages	Read only
Datasets	Read only

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 Sigma, and complete the required parameters.

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

Field Name	Description
Connector Type	By default, "Sigma Computing" 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
License Add Ons	Auto Lineage Supported Data Quality Not Supported Data Access Not Supported Select the checkbox for Auto Lineage Add-On to build data lineage automatically.
Connector Name*	Enter a unique name for the Sigma Computing connection (Example: "Sigmacomputingdb").
Connector Environment	Select the environment (Example: PROD, STG) configured for the connector.
Connector Description	Enter a brief description of the connector.
Host Name*	Enter the Sigma IP address or hostname of the source system to establish a connection.
Connection String	Configure the connection string for the Azure Devops Repo database: Automatic mode: The system generates a connection string based on the provided credentials. Manual mode: Enter a valid connection string manually. Replace placeholders with actual database details. {sid} refers to the database name.
Client Id*	Enter the client ID generated for the service account that has been granted catalog access permissions.
Client Secret*	Enter the client secret associated with the specified client ID to authenticate the connection.
Proxy Enabled*	Select Yes to route API calls through a proxy server. Select No to bypass the proxy and connect directly.
