在BigQuery表中添加新列的成本是多少？

Question

I tried to search for this and found that from "Free operation" section of https://cloud.google.com/bigquery/pricing

You are not charged for list, get, patch, update and delete calls. Examples include (but are not limited to): listing datasets, updating a dataset's access control list, and updating a table's description.

But I am not sure if this also means table schema update.

As I can assume because BigQuery is a columner data storage , Adding a new column should not incur any cost.

Answer 1

Adding a new column does not incur query or storage costs. The new column will have NULL values for all existing rows in the table.
