> For a join sql like A join B. The implementation of SortMergeJoinPlan
> currently inits the two iterators A and B one by one.
> By initializing A and B in parallel, we can improve performance in two
> aspects.
> 1) By overlapping the time in initializing.
> 2) If one child query is null, the other child query can be canceled since
> the final result must be null.
