   > 1. Figure out a way to compute costs that encourages the SQL planner to push projects and filters above joins consistently.
   
   @gianm Thinking of different ideas....in addition to what we already have now... is it possible to add a new RelOptRule that when see two DruidJoinQueryRel, will push filter to the topmost DruidJoinQueryRel if the filter is on the inner DruidJoinQueryRel?
