yeah, I tried that initially but the issue is that csv1 will be processed into the Silver bucket...all good here. Then the next day csv2 will land in the same Bronze S3 bucket as csv1, and it will have all the rows from csv1 and possibly some new data or updated data. Next time the batch runs, it will read both of these files therefore duplicating data in Silver. So that's why I tried AutoLoader...because it keeps track of which files it has already processed in the source. i'm getting ready to try the manifest file idea now....more soon
