Just wondering what the ‘backfill’ means?

Questions & Help
1

Hello! So glad that the Canadian weekly patterns have already been available. Just wondering what the ‘backfill’ means? And then the directory hierarchy for the Apr 26-May 16, 2021 backfill contains ‘weekly’ and ‘test_delivery’ subdirectories. I wonder what’s the difference? Or is ‘test_delivery’ just for testing purposes? Thanks again!

Also, would like to add to my question. How come the Apr 26-May 16, 2021 data have been split into 5 parts for each week? While the rest of the data was 1 file per week? Thanks again!

Thanks for your answers Jeff! Also, when you mean by “full Canadian history”, do you mean getting a backfill of the weekly patterns data (prior to the May 2020 data)?
