ok i just saw the FAQ (http://wiki.apache.org/cassandra/FAQ#batch_mutate_atomic)
follow up question ... it states that "As a special case, mutations against a single key are atomic, but more generally no" ... i interpret that to also mean " .. mutations against a single key in the same CF ... " so if i have several mutatations against a single key, but multiple column families i assume this is not atomic? thx On Fri, 2010-08-06 at 11:08 -0700, Todd Burruss wrote: > if i am using batch_mutate to update/insert two columns in the same CF > and same key, is this an atomic operation? > > i understand that an operation on a single key in a CF is atomic, but > not sure if the above scenario boils down to two operations or > considered one operation. > > thx >
