> In POFRJoin implementation POLocalRearrange is used to extract join keys from
> the input tuples. If keys match then to perform actual join input tuples are
> fed to Foreach which does a cross on its inputs. After keys are extracted
> using POLocalRearrange output; function getValueTuple(POLocalRearrange lr,
> Tuple tuple) is called to reconstruct the input tuple. It seems that this
> function call is unnecessary since we already have input tuple at that time.
> This is not a bug, but since this function would get called for every tuple,
> if it is eliminated, it should certainly help to improve performance.
