when we dont use aggregator in mapping ?..

Aggregator transformation is used to calculate values in a
group. It is the only t/r which can be used for aggregate
calculations e.g: Sum,avg,max,min,count....

So when we don't need any such aggregate calculations, than
we don't use aggregator transformation.
