I have a question about how replication works. Say you have 4 replicated caches: A, B, C and D. Assume also that cache A is the coordinator. When something is put into cache B and the change gets replicated out to the other caches, is the change:
1) sent first to the coordinator (A) and then from A to the other caches (C and D), or
2) does the change propagate directly to all other caches from A.
