What are the rank caches?..

Answer / swetha

During the session ,the informatica server compares an inout
row with rows in the datacache. If the input row out-ranks a
stored row, the informatica server replaces the stored row
with the input row. The informatica server stores group
information in an index cache and row data in a data cache.
