Curt Monash (Introduction to MemSQL) and GigaOm (Ex-Facebookers launch MemSQL to make your database fly):
As its name implies, MemSQL achieves its fast performance in part by keeping data in memory, but it doesn’t use memcached like Facebook does to keep its massive MySQL deployment up to speed. Rather, MemSQL takes a lesson learned from HipHop — Facebook’s tool for converting PHP code into faster C++ — and converts SQL to C++.
Another one… good to see innovation being back in SQL Land 🙂
