When the aggregator transformtaion executes all the output
data will get stored in the temporary location called
aggregator cache. when the next time the mapping runs the
aggreagator transformation runs for the new records loaded
after the first run. These output values will gets
incremented with the values in the aggregator cache. Thia
is called incremental aggregation. By this way we can
improve performance...
