Hi Sam, we are using syncrepl mechanism, and we don't decide yet if the consumer will point to a specific IP ( let's say half of consumer on multimaster1 and the rest on multimaster 2) or pointing to Virtual IP of a RADWARE that is in charge of balancing ( only failover not load balancing).
In any case, I have to implent or found a solution more general as possible, in order to handle the two scenarios. If you have any suggestion or something already implemented I will appreciate your help.
