Answer: Use gsutil to batch copy the files in parallel.
The question focuses on optimizing batch file transfers to Cloud Storage for staging before ETL processing. Option B (using gsutil to batch copy files in parallel with the -m flag) is the correct choice because it leverages parallel processing to maximize transfer speed and efficiency, which aligns with Google Cloud best practices for large-scale data ingestion. The community discussion strongly supports B with 94% consensus, citing gsutil documentation and performance benefits. Option A (sequential transfer) is inefficient for large batches. Option C is incorrect as gsutil does not perform extraction—it only handles file transfer. Option D is misaligned since loading is part of ETL, not the transfer/staging step.

You are designing a solution for Mountkirk Games to optimize batch file transfers of game statistics into Cloud Storage. The files need to be staged for processing by an extract, transform, and load (ETL) tool. What is the recommended approach?
A
Use gsutil to batch move files in sequence.
B
Use gsutil to batch copy the files in parallel.
C
Use gsutil to extract the files as the first part of ETL.
D
Use gsutil to load the files as the last part of ETL.
