Answer / srikanth
HI
Among those 3 trans, filter does not use cache.
so it should be either agg or sorter.
Both agg and sorter uses cache as they process data in a
dependable fashion for performing calculations and sorting
data before the result is passed to next transfomration.
WE cant say which one uses more space. it depends on the
size of source data we are processing.
Agg needs to perform calculations on groups of data but if
the data in sorter is more, it takes more space than agg to
hold the data.
for ex, we are sorting on character data, server needs to
use ASCII values of alphabets to sort in order.
It depends on the size of the source data.
