There was a problem hiding this comment.
The change itself is straightforward. We provide the most substantive guidance about value handling https://pkg.go.dev/cloud.google.com/go/bigquery#RowIterator.Next, is there anything you think we should include there to clarify this behavior?
I added more information on that section about empty vs null arrays, do you think looks good ? |

BigQuery translates a NULL array into an empty array in the query result, although inside the query, NULL and empty arrays are two distinct values. This change brings the translation on the Go side more similar to the BQ backend. More on: https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types#array_nulls
Resolves #4950 #9383
