[389-users] Re: Documentation as to how replication works

Ultimately, I think I mostly understand now. A change happens on a replica, it assigns a CSN to it and updates its RUV to indicate that that's now the newest CSN it has. Then a replication event occurs with its peers and those peers basically say "you have something newer; send me everything you originated after this last CSN from you that I know about". And then a replication event happens to their peers and they see that there's something new from that replica, etc.

Kind of, but it's the other way around: the supplier server with the new changes connects to a peer server and retrieves its ruv. From that it decides which of the changes it should to send. The consumer server doesn't ask for anything directly. The process is supplier-initiated.
