AWS S3 Bucket Unique Identifiers
Is using the combination of properties function standard practice, when importing AWS data via Cloudworks or is getting a unique identifier added many times better?
Currently the csv has no unique ID but I will push for one from my AWS admin if any examples can be mentioned. Its an AWS Detailed Billing Report with c14m rows for what its worth.

Yes, using a unique identifier is better (and faster) than using a combination of properties on an import.
So if it is possible to generate a unique code I would advise that.
I don't have any metrics on how much faster, but should be quite noticeable on a large list.1
