if u wont use the sorted input the aggregator transformation will reads the records and keep until all the calculations are done.
if we provided the sorted input it reads the records and release the records reaching next first record of new group.
the integration service will creates the cache for only the sorter keys and only one cache in sorter t/r. so by providing the sorted input we get the performance advantage.
