Do you have an example application where this particular side effect
of eventual consistency is problematic? Obviously memcached and
Cassandra are different because of eventual consistency. The question
is whether they are different enough to break an inconvenient number
of real applications. Do you depend on add returning a unique number
to each client in an application you've deployed? I have always
imagined it as being primarily for simple counters.
