Hi,



As suggested in the Mondrian spec, mondrian.rolap.aggregates.ChooseByVolume
determines whether to choose aggregate tables based on volumn or rows. My
question is that is there any study on this property to tell which method
(ByVolumn or ByRows) to choose aggTables is better under which
circumstances? If so, has Mondrian been evaluated against this property?
What is the result like? This information would be quite useful when coming
to tuning Mondrian for selecting aggregate tables?



Can anybody shed some light on this? I would be greatly appreciative if you
could help.



Thanks

Jie
