[infinispan-dev] Distributed execution framework

Thanks for writing this up dude.  It's nice and clear, pretty much what I had in mind.

A few points.

First, the section on Distributed Tasks Input.  I am guessing what you are trying to model here is access to the actual cache?  Doesn't the Callable in question just need a reference to the Cache?  Not sure I get what you mean by node-local data.  Are you assuming a view of global state that is locally resident on a node in question?  If so, double-counting may still happen if the task ends up on 2 nodes, both of which happen to own an entry.

Second, failover, perhaps initially we could just ship with a simple policy of throw an exception if a node fails.  And later add more failover and task migration policies.  I'd prefer to start simple and build out more complex features.  :)

Cheers
Manik
