>             Project: Infinispan
>          Issue Type: Enhancement
>          Components: Distributed Execution and Map/Reduce
>    Affects Versions: 5.2.0.Beta6
>            Reporter: Thomas Fromm
>            Priority: Minor
>
> 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
