Reservation cost attribution

This feature lets you attribute reservation fees back to the specific query usage across any projects that used the reservation. This results in more accurate net costs on a per-project basis.

All BigQuery Reservations API customers have an "Analysis Slots Attribution" line item in their Cloud Billing data, indicating the share of the reserved slots consumed in each project. This includes both the Billing portal and the Cloud Billing export. The cost for this new item is zero. The changes don't affect your invoice totals.
