             Summary: Enhance Mapper API with lazy loaded value
                 Key: ISPN-2686
                 URL: https://issues.jboss.org/browse/ISPN-2686
             Project: Infinispan
          Issue Type: Enhancement
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 5.2.0.Beta6
            Reporter: Thomas Fromm
            Assignee: Vladimir Blagojevic


In situations where Map/Reduce is used and the value is not (always) needed at the Mapper, the value could be loaded lazy, when the map(..) interface is slightly changed:

map(Entry<KIn, VIn> entry, Collector<Entry<KIn, VIn>> collector) 

When entry.getValue() is called, the value should be loaded from store or maybe remote node.

Maybe this change to Entry would be also useful for event api ISPN-1802
