Use rank transformation to return top or bottom N-no of position, it uses rank cache to perform rank. In rank cache it contains both index as well as data cache.
Index cache contains GROUP BY parts, while data cache contain calculated RANK values.
Rank cache is temporary and is cleaned up at end up session run.
