Answer / srikanth
By using sorted input by performing calculations on groups
of data, informatica server need not to use cache for
holding data to perform calculations for a particular group
as the source data already comes in sorted order. Hence
reduced burden on informatica server, just performing
calculations which is a performance issue.
Ex: for calculating sum of salaries department wise, if
data comes in random order, server need to use cache for
holding data until all the entries for a particular
department is calculated (deptno 10,20....).
by using sorted input, server does not use cache and just
perofrms calculations assuming teh data comes in sorter
order thus improvement in performance.
