BigQuery Ingestion Guide: Setup & Prerequisites

To configure ingestion from BigQuery, you'll need a Service Account configured with the proper permission sets, and an associated Service Account Key.

This setup guide will walk you through the steps you'll need to take via your Google Cloud Console.

BigQuery Prerequisites​

If you do not have an existing Service Account and Service Account Key, please work with your BigQuery Admin to ensure you have the appropriate permissions and/or roles to continue with this setup guide.

When creating and managing new Service Accounts and Service Account Keys, we have found the following permissions and roles to be required:

  • Create a Service Account: iam.serviceAccounts.create permission
  • Assign roles to a Service Account: serviceusage.services.enable permission
  • Set permission policy to the project: resourcemanager.projects.setIamPolicy permission
  • Generate Key for Service Account: Service Account Key Admin (roles/iam.serviceAccountKeyAdmin) IAM role
note

Please refer to the BigQuery Permissions and IAM Roles references for details

BigQuery Setup​

  1. To set up a new Service Account follow this guide

  2. When you are creating a Service Account, assign the following predefined Roles:

note

You can always add/remove roles to Service Accounts later on. Please refer to the BigQuery Manage access to projects, folders, and organizations guide for more details.

  1. Create and download a Service Account Key. We will use this to set up authentication within DataHub.

The key file looks like this:

{
   "type": "service_account",
   "project_id": "project-id-1234567",
   "private_key_id": "d0121d0000882411234e11166c6aaa23ed5d74e0",
   "private_key": "-----BEGIN PRIVATE KEY-----\nMIIyourkey\n-----END PRIVATE KEY-----",
   "client_email": "test@suppproject-id-1234567.iam.gserviceaccount.com",
   "client_id": "113545814931671546333",
   "auth_uri": "https://accounts.google.com/o/oauth2/auth",
   "token_uri": "https://oauth2.googleapis.com/token",
   "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
   "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/test%suppproject-id-1234567.iam.gserviceaccount.com"
}

Next Steps​

Once you've confirmed all of the above in BigQuery, it's time to move on to configure the actual ingestion source within the DataHub UI.
