> It would be nice if infinispan could provide a way to the common problem of searching and retrieve the first non null value.
> My attempt was to use the map reduce framework, but it would still scan all the keys and value even if the result as been found. Maybe Infinispan could provide a way to "stop" the map-reduce operation on all nodes when asked, ex, when the first non null value has been found ?
