You must have a ddw-catalogs dataset set up to hold your catalog files when you are done running the collector.

If you are using Catalog Toolkit , follow these instructions to prepare the datasets for collectors.

Setting up authentication for BigQuery connects to BigQuery using a Service Account associated with your project.

To set up authentication for BigQuery:

  1. Create a service account with the following roles BigQuery Data Viewer and BigQuery User. For additional information on predefined roles and permissions, see Google Cloud Platform documentation.

  2. After you create a service account, create a key for the account and download the associated JSON key file.

  3. Place this key file on the machine from where you plan to run the collector. You will need this file while running the collector.
