I'm currently building an app loading data from hundreds of Excel files.
One new file each date containing about 10,000 rows. I'm now about to enable incremental load in my script but not sure which approach to use. Is it for instance possible to exclusively load/add "todays file"? Last modified file etc?
I guess using unique ID-keys (I have to put them toghether myself) searching through millions of fields would be about as time consuming as doing a full reload?
