> This is to add queue number for queries after they were launched, in order to
> give users an idea of the sequence in which their queries were launched. Or
> in other words, to give them an idea of how many queries were launched before
> them which are still competing for resources with their query.
> Giving queue numbers from waiting query collection may not be correct as they
> are not consistent. When a candidate query is picked up from waiting state,
> it is removed from the collection and checked for cost constraints. If it
> fails the constraints, the query is added back to the waiting query
> collection. This causes inconsistency in terms of indices of queries within
> the collection. Because of this inconsistency, user might see their queue
> number increasing.
