if we r using aggregator we enabled sorted input but the
records r not sorted what happen?
Answers were Sorted based on User's Feedback
When the 'Sorted Input' is enabled and if the data is not
sorted, then unexpected results will occur. It means the
session will succeed but the end result may not be the way
as per the business requirement.
Another point to be remembered is:
Group by columns in the Aggregator transformation must be
in the same order as they appear in the Sorter
transformation

Answer / vaibhav bhandeo
This technique is used when you want a performnce boost.
There will be an aggrigator cache created and will be
indexed. Although you have not given a sorted input it will
still work fine as it is indexed in cache. Please note this
is not like a page fault where you have to bring the page
from the secondary memory when not found in primary memory.
