How many records can the wix database handle?

If I am pulling data from the backend and not displaying it in the front end (where things can get temperamental), how many records can Wix handle?
Can I add 100k or as much as 1 million records into Wix?
(assuming 10 columns per record with maybe 2 of those 10 being screenshot image uploads and the rest just text)

Can Wix backend handle it?

And on a front end question, can Wix handle 50,000 visitors visiting 10,000 dynamic pages throughout the course of a day without performance issues (payments being made etc.)?

I’d really appreciate answers to my specific questions. Thanks a lot in advance!

General DB limits are as follows:

500KB per record. There are no limits to number of fields.
10GB per site (millions of records)

Thank you.
