• The query on the left was able to process 2.2 TB in 20 seconds. Impressive, but costly.
• The query on the right went over a similar table — but it got the results in only 5.4 seconds, and for one tenth of the cost (227 GB)

I see that the amount of data processed is different. So in 1st point 2200 GB processed in 20 sec and in 2nd point 227 GB in 5.4 sec. Am i missing anything?
