Setting Up Impersonation for Google BigQuery

If you are using Google BigQuery as a data warehouse and Google G Suite directory to manage users and groups that have access to AtScale and published cubes, you can set up impersonation for Google BigQuery.

Before you begin​

If you are an administrator or Super User for your AtScale organization, Impersonation is enabled from the Create a Data Warehouse dialog for Google BigQuery. To enable impersonation, choose Settings from the top navigation menu, then select Data Warehouses. Click on CREATE DATA WAREHOUSE, select Google BigQuery as the Data Warehouse type, and then enable Impersonation from the ensuing dialog.
