Code Review
This pull request introduces a new code sample and test for performing a BigQuery dry run query using BigQuery DataFrames. The feedback suggests removing an unnecessary global configuration for ordering_mode since no DataFrame operations are executed, and adding a safety check for query_job.total_bytes_processed to handle cases where it might be None and ensure type safety.
