> DemensionAsMeaures is a way to get the SQL query's result directly through making use of Calcite, when several special measures cannot be matched with the pre-calculated cube. But it should only support the Max and Min when selected from the fact table, because the data in cubes has been aggregated so as to inaccurate results.
