Also pinging on this one, maybe if I rephrase the questions I'll get an answer.
Does riak have a last modified field which can be used in a map reduce job, to say get updated values from a timestamp? Are last modified times copied when replicating a K/V across data centers with EDS? Is there some other scheme I could use to determine what has been replicated?
