The reason for my question is MySQL's "cluster" support.
My reading of it is that their "clusters" have nothing to
do with what used to be called clusters - groups of
machines that share disk but not memory. The MySQL site
claims that their clusters give "high availability" aka
"5 nines". Looking more closely, "5 nines" means 99.999%
up time. Sounds good. 0.001% of a week is 10 minutes.
