Koha is, as we speak, in the process of transitioning from using MySQL
as its underlying repository, to using Index Data's Zebra
(http://indexdata.com/zebra), which is optimised for databases such as
large bibliographic sets.  To my knowledge, it is used for the Danish
national union catalogue, which has in the region of 30 million
records, and performs extremely well there.  It has also recently been
adopted (though not yet rolled out) by another institution that is
using it for its 20-million-record union catalogue.  There's no reason
to think it wouldn't work just fine with larger data-sets (but the
only larger data-set I know of is OCLC's WorldCat, so the issue
probably doesn't arise.)

Like Koha, Zebra is free (open source) software.
