We discussed it number of times, including (but probably not limited to): - http://lists.jboss.org/pipermail/infinispan-dev/2016-February/016414.html - http://lists.jboss.org/pipermail/infinispan-dev/2016-March/016490.html
You might also want to look into the internal lists... The biggest question - has anything changed? Do we have any other idea?
