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.
