Does wikimedia currently use MySQL enterprise edition
or community
edition?
wikimedia uses four-oh-forever ;-) (4.0.40, in-house fork), though
some servers are still at 4.0.26.
there is a plan of going up to 5.0, with incorporated innodb
scalability fixes (announced by google at mysqlconf a month ago) -
that way we may go after far more evil sharding, and with better data
locality - after full 8-core boxes CPU load. in theory. :)
