| Map<TOuterKey,TMapInput,TInnerKey,TReduceInput>(IStreamable<TOuterKey, TMapInput>, Func<IStreamable<TOuterKey,TMapInput>,IStreamable<TOuterKey, TReduceInput>>, Expression<Func<TReduceInput,TInnerKey>>) |
The Map phase of a single input map/reduce operation. Allows the specification of streaming logic on the mapper, and a key selector for the next (reduce) stage. |
| Map<TOuterKey,TMapInput,TReduceInput>(IStreamable<TOuterKey,TMapInput>, Func<IStreamable<TOuterKey,TMapInput>,IStreamable<TOuterKey,TReduceInput>>) |
The Map phase of a single input map-only operation. Allows the specification of streaming logic on the mapper. |
