Let me ask a (probably) stupid question. How is the sync rep
different from RAID-1?
When I first saw sync rep, I expected that it would provide the same
guarantees as RAID-1 in terms of durability (data is always mirrored
on two servers) and availability (if one server goes down, another
server continues full service).
What you describe is most like A-sync rep.
Sync rep makes sure that data is always replicated before confirming to
writer.
Really? RAID-1 is a-sync?
