Hi,

My understanding of how REPL_SYNC replication works is that on a user commit:
-locks are obtained for the keys on remote caches (during prepare)
-if the locks are successfully obtained, the cache commits and then replicates the changes to the remote instances

With REPL_SYNC and syncCommit=true it seems like there is the potential to optimize out one of these network round trips with more 1PC like semantics - we already do not have a success guarantee after the first phase (replication can fail).  

Is there a way to configure JBoss Cache to not obtain locks on remote instances during the prepare phase, and just try to replicate the changes during the commit?

Thanks,
Adam
