Himanshu Gahlaut commented on LENS-630:
---------------------------------------
Apart from cumulative query cost calculation, another example of client code
which can be thought of while designing a QueryCost interface is
PriorityDecider in HiveDriver. The QueryCost interface built should be able to
return a cost using which PriorityDecider code can decide priority.

> Along with this, we can add a new field in QueryCost to return the query cost
> calculated by the implementation. normalizedQueryCost could be one name for
> that field.
