                 Key: ISPN-2923
                 URL: https://issues.jboss.org/browse/ISPN-2923
             Project: Infinispan
          Issue Type: Feature Request
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 5.2.5.Final
            Reporter: Mathieu Lachance
            Assignee: Vladimir Blagojevic


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 ?
