Re: [infinispan-dev] transaction/query/mapreduce over hotrod

Mircea, I applaud the effort and your experiment! Having said that I think we have to engineer a much more plumbing for more complicated cases, e.g map/reduce (marshalling results, classloading etc etc). I am more and more convinced nowadays that all of this plumbing is better provided by AS itself rather than us reinventing the wheel here... WDYT?
