Domain 4.4: Managing storage and database solutions — GCP ACE Practice Question 38

How to approach this question

Identify the tools that provide query validation and byte estimation without execution.

Full Answer

BigQuery charges based on the amount of data processed (bytes read). Before running a query, you can see the estimated bytes processed in the top right corner of the BigQuery Console UI. Alternatively, using the CLI, you can append the `--dry_run` flag to the `bq query` command. Both methods are free and do not execute the query.

Common mistakes
