You need to optimize batch file transfers into Cloud Storage for Mountkirk Games' new Google Cloud solution. The batch files contain game statistics that need to be staged in Cloud Storage and be processed by an extract transform load (ETL) tool. What should you do?

The correct option is to use gsutil to batch copy files in parallel. gsutil is a command-line tool for interacting with Cloud Storage, and its cp command supports parallel uploads for multiple files, significantly speeding up batch transfers. This is ideal for staging game statistics efficiently. Using gsutil to batch move files in sequence would be slower than parallel processing, especially for a large number of files. Extracting or loading files as part of ETL are functions typically handled by dedicated ETL tools or services (like Dataflow or Dataproc) after the files are staged in Cloud Storage, not by gsutil itself for the primary transfer. gsutil is primarily for data movement and management within Cloud Storage.
