Nop Commerce Suggest to Upload 500 to 1,000 records at once.
so is it possible to upload thousands of record for e.g 50,000 to 1 Lac Record using the bulk import functionality of nopCommerce?
I tried the bulk importer but because of all the tracking in EntityFramework and the event published it was way to slow.
If you are comfortable with EF I suggest running some more targeted batches directly on the repositories like products, categories, tags and the corresponding mapping tables. You will need to write a custom plugin though.
