Yes, I have.
There are millions of videos available from the Pornhub API alone.
Tube Ace utilizes the native WP function wp_insert_post() to insert the API results as posts into the WordPress database.

Databases can also contain massive number of rows and huge size of entries. A MyISAM storage engine supports 232 rows per table, which is far far more than what average websites need.
WordPress creates entries other than the original post itself in the database. Each post can have unlimited meta attached to it, limited by the database itself. So if your posts are going to have a lot of meta data (Images, Custom fields, etc) then doing a heavy task such as a complicated meta query is gonna take considerable time and resources.
It is worth mentioning that you should clean up your database once in a while, to avoid unwanted performance decrease. You can either optimize it using scripts such as PHPMyAdmin or by using WordPress plugins.

You sure can. Wordpress doesn't limit the quantity of posts, taxonomies, users etc.. you can have on your site. It all depends on the capability of your host service.

But, as Cesar says, you are going to need a robust hosting plan (dedicated servers, maybe cloud-based content) to do it correctly.
