"The CrossJoin change was to make the optimizer less optimistic"

Sounds like we will end up with what Julian calls a pessimiser :)

Change 8900 by emberson at bortei.head on 2007/03/20 15:28:08

	MONDRIAN
	   Revised RolapResult evaluation algorithm and the CrossJoin non-empty
	   optimization algorithm.
	   The CrossJoin change was to make the optimizer less optimistic so that
	   it would include values that occur in corner cases. It also
	   cached information between invocations.
	   Added ability for Calc's to cache evaluation data in the Query object.
	   Made the ResultLimit check also work when an Iterable, rather than a
	   List, is used to generate the RolapAxis object.
	   Enable test RolapResultTest.java testD2
