   @Jackie-Jiang Thank you. 
   
   Till some extent we are able to use star tree index with around 30 columns 
whose cardinality is around 100s. Since our requirement is adhoc query analysis 
we cannot make a star tree which fits most of the cases mainly when we have 
high cardinality columns(20000+). Where as our MVs serves 95% adhoc queries.
