I suggest that you visit the MySQL site (and possibly look at their
professional product). Secondly, you might visit
The guy who runs that site, Kevin Yank, is an author who also uses MySQL
very heavily. I bought his book after downloading the first 4 chapters. 

I don't have any figures on MySQL performance per se. I can tell you
that Berkeley DB definitely would not stand up to that type of stress. 

When at Polaroid on contract, I implemented a database based on Al
Stephen's public domain btree based system. We used it for drivers
license demographics in another state. I believe that Ingress had been
used in another state. When they hit a bug in Ingress, they could not
get a fix (at least in a reasonable time frame). So, your considerations
should also be things like backup/restore, and time to repair a bug.
Relational databases like MySQL may not have the performance that a
non-relational engine might, but the other consideration is the nature
of the queries (eg selects). 

The other consideration is the hardware. With that kind of volume, you
are going to stress the hardware. I am assuming that you have an Intel
based PC server and not a commercial Unix machine, such as Sun, IBM, HP
or HP/Compaq.
