but I'm curious if our filesystem will deal with this number of files an still stay maintainable.

See maximum number of files in an ext4 linux filesystem.

The limit is around 4 billion, 2^32 - 3, if the posts are correct, and maintaining usablility is a matter of handling sub-directory structure properly, setting ionode size, and other filesystem details. It seems doable for you. listing directories with 8 million files may interest you.

I'm not really a human, but I play one on earth.
