A financial services company relies on a legacy system that generates output files in CSV format and stores them in Amazon S3. The company is adopting a new third-party analytics platform that supports advanced SQL queries but can only read data from Amazon Redshift or S3provided that the data is in a compatible format. The legacy application cannot be modified to change its output format. What is the most efficient solution, requiring the least operational maintenance, to make the CSV data usable by the new analytics tool?
