Are live writes replicated in real time, or are they locally staged (which is what Facebook does, I believe)

Also, do you mimic the eventually consistent behaviour of AWS, or do you offer a stronger form of consistency?

Live writes are written out with 4x redundancy in the local zone, then asynchronously replicated out to the remote zone. Some time later, it is erasure coded into a more space-efficient format, independently in each zone.
