Connect to Stardog

The Stardog Enterprise Knowledge Graph Platform provides a foundation for a flexible semantic data layer designed to answer complex queries across data silos.

You can integrate your Databricks SQL warehouses (formerly Databricks SQL endpoints) and Azure Databricks clusters with Stardog.

Connect to Stardog manually

This section describes how to connect to Stardog manually.

Note

You can use Partner Connect to simplify the connection experience for a SQL warehouse.

Requirements

Before you connect to Stardog manually, you need the following:

• A cluster or SQL warehouse in your Azure Databricks workspace.

  • Compute configuration reference.
  • Create a SQL warehouse.

• The connection details for your cluster or SQL warehouse, specifically the Server Hostname, Port, and HTTP Path values.

  • Get connection details for an Azure Databricks compute resource.

• An Azure Databricks personal access token or a Microsoft Entra ID (formerly Azure Active Directory) token.. To create a personal access token, follow the steps in Azure Databricks personal access tokens for workspace users.

  Note

  As a security best practice, when you authenticate with automated tools, systems, scripts, and apps, Databricks recommends that you use personal access tokens belonging to service principals instead of workspace users. To create tokens for service principals, see Manage tokens for a service principal.
