Say, we have two Hazelcast clusters located in two locations, namely London and Tokyo and we configure WAN replication in active-active mode to replicate a distributed map between them.
If one of the clusters, say London, is completely down. After resuming to services, we found that Hazelcast will not repopulate the data from Tokyo to London and leave London with an empty map.
My question is, if we want to repopulate the data to the downed site after coming back up, what can we do?
ps 1: Do you normally expect a distributed cache to behave like this?
ps 2: In this similar situation, what do you normally do to "recover"?
Thank you!!
