Describe, in detail, 2 real-world examples of possible data files of at least one billion rows, how long you think it takes, on average, to process them, and why it would be important for a business to be able to process such files as quickly as possible. You can use arenas such as social media, banking, worldwide weather statistics, or anything else that you can think of. How would you use the methods that were covered in this and the previous module to optimize processing times for such files?
