I've just started mucking about with Datamapper & merb and came across this from the DataMapper "Why Datamapper?" page. "ActiveRecord updates every column in a row during a save whether that column changed or not. So it performs work it doesn't really need to. Which is much slower, and is likely to eat data during concurrent access if you don't go around adding locking support to everything." Just sharing, I too am perfectly ok with the way ActiveRecord handles updates. On Jan 24, 2008 2:29 PM, Colin A.
