I have set up delta-syncrepl between provider A and consumer B, and it seems to work ok. Online updates to A are synch'ed to B. However, about once a month, there is a large update which contains hundreds of million records. Online update is going to take days. I tried to bring A offline, do slapda

I'd probably set it up a little differently. Something like this (very general/generic): 2 of your 6 servers as suppliers/masters, accepting writes. If you are using a load balancer, set it up so that you have a vip that always goes to one of these servers (the "primary" supplier), and directs t
