A couple more thoughts. Maybe create: setNodeOrdering and getNodeOrdering, as well as make the ordering of nodes be automatically inherited. This might be better expressed as regions, but there may be thousands of regions for handling POJOs. And as for replication or cache storage, I'm not clear on how this might be handled. Perhaps this is just a hack? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984356#...
