You have an Azure Storage account that contains 100 GB of files. The files contain rows of text and numerical values. 75% of the rows contain description data that has an average length of 1.1 MB.
You plan to copy the data from the storage account to an enterprise data warehouse in Azure Synapse Analytics.
You need to prepare the files to ensure that the data copies quickly.
Solution: You modify the files to ensure that each row is less than 1 MB.
Does this meet the goal?

Answer options

Correct answer: A

Explanation

The solution of modifying the files so that each row is less than 1 MB is effective because it allows for faster data transfer, as many data transfer processes perform better with smaller payload sizes. The original average row size of 1.1 MB could lead to slower copying times, hence reducing it below 1 MB meets the goal. Therefore, option A is correct, while option B is incorrect as it contradicts the benefits of reducing row size.
