"... | Applies a GroupCombineFunction on a grouped {@link DataSet}.
A CombineFunction is similar to a GroupReduceFunction but does not perform a full data exchange. Instead, the
CombineFunction calls the combine method once per partition for combining a group of results. This
operator is suitable for combining values into an intermediate format before doing a proper groupReduce where
the data is shuffled across the node for further reduction. The GroupReduce operator can also be supplied with
a combiner by implementing the RichGroupReduce function. The combine method of the RichGroupReduce function
demands input and output type to be the same. The CombineFunction, on the other side, can have an arbitrary
output type.
@param combiner The GroupCombineFunction that is applied on the DataSet.
