It seems that if you create a query with a date-range outside the scope of the corresponding entity, the job takes much longer than if the range is within the scope. For example, consider a campaign with data from August 10th - August 15th. A query from Aug. 10 - 15 would run at a reasonable time, while a query from Aug 1 - 30 would take a much longer amount of time, even though the extra dates contain no additional data. I was wondering if this is to be expected, or if this is potentially an issue with implementation? Thanks!
