We're moving from RBO to CBO. For those of you who use CBO, what mode do you use FIRST_ROWS or ALL_ROWS? And why?
My thinking is if it's a database where most of the querying is done on small sets of records, then we may want to use FIRST_ROWS. On the other hand, if our database is used to generate sizable reports, we might use ALL_ROWS. I also understand that we can always change it per session (with alter session) and per query (with hints).
