VVR on Windows Performance/Latency
I'm setting up a system that requires an RPO-0 disaster recovery between two database clusters. Because the distance is over 400km between them I'm going to use VVR in a bunker configuration about 30km from the primary database cluster. Communications between the bunker and the primary DB cluster will be sychronous (in sync override mode) From Primary to secondary will be async.
Does anyone here have any experience with such a configuration? If so, can you provide any feedback? Especially, how much of a performance hit have you seen on average?
