kx has been doing this for ~4 years in the financial space. There's also at least one company selling software based on it in other industries...

kx is on its second major version and legitimately handles 1m-100m records per second and historical/real time databases in memory and on disk of unlimited size using standard linux/solaris/win hardware, filesystems, etc.

q, the latest version, is the k language w/ sql syntax embedded.
