Loading/unloading data to/from Amazon S3

This scenario describes a Job that generates a delimited file and uploads the file to S3, loads data from the file on S3 to Redshift and displays the data on the console, then unloads the data from Redshift to files on S3 per slice of the Redshift cluster, and finally lists and gets the unloaded files on S3.
