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 convert the files to compressed delimited text files.
Does this meet the goal?

Answer options

Correct answer: A

Explanation

Converting the files to compressed delimited text files significantly reduces their size, which helps to improve transfer speeds when copying the data to Azure Synapse Analytics. This compression optimizes bandwidth usage and decreases the amount of data that needs to be moved. The other option, 'No', is incorrect because not compressing the files would likely result in slower data transfer times due to the larger file sizes.
