We are here considering the *full replication mode* of Infinispan, in which every node maintains all copies of the same data items. This implies that there is no need to fetch data from remote nodes during transaction execution. Also, Infinispan was configured NOT TO use eager locking. In other words, during transaction's execution Infinispan acquires locks only locally.

So are you suggesting that this scheme maintains a single, global master node for the entire cluster, for *all* keys?  Doesn't this become a bottleneck, and how do you deal with the master node failing?
