Appendix: Enabling Private IP Requests in BigQuery from a VPC (in case you need to)

1. Enable Private Google Access for your VPC network:

1. Go to the Google Cloud Console: https://console.cloud.google.com/
2. Navigate to VPC Networks under Networking > VPC Network.
3. Click on the name of the VPC network you want to modify.
4. Click on "Edit" at the top of the page.
5. Scroll down to the "Private Google Access" section.
6. Select "On" for the "Private Google Access" option.
7. Click "Save" to save the changes.

2. Create a Cloud NAT Gateway (if you don't have one) to allow instances without an external IP address to send traffic to Google APIs and services:

1. Go to the Cloud NAT page in the Google Cloud Console: https://console.cloud.google.com/networking/nat
2. Click "Create NAT Gateway".
3. Enter a name for your NAT gateway.
4. Select the region and VPC network where you want to create the NAT gateway.
5. Configure the Cloud Router, IP addresses, and other settings as needed.
6. Click "Create" to create the NAT gateway.

3. Configure BigQuery connections:

1. Go to the BigQuery Console: https://console.cloud.google.com/bigquery
2. Click on your project name and then click on "Project settings".
3. Under "Data access", click "VPC Service Controls".
4. Click "Add VPC Service Controls".
5. Select the VPC network you enabled Private Google Access for.
6. Click "Add" to apply the VPC Service Controls to BigQuery.

Now, BigQuery will be able to receive private IP in the request to access from your VPC network. Instances with private IP addresses in your VPC can access BigQuery securely without an external IP address.
