Re: [infinispan-dev] Invoking distributed exec and mapreduce over hotrod

Well, I feel exposing M/R over Hot Rod - from a protocol standpoint - would require a platform-independent mechanism of defining a closure (keeping in mind we need to allow this from non-Java clients too). So I reckon Javascript is the way to go, at least from a protocol standpoint. Now how we expose this in remote client APIs (Java, Python, etc) needs some thought, but at first glance it would seem as though we won't have a direct mapping to what we do on the embedded side of things.
