Hi Wes, Thanks for the report! I like it (mostly because it's short and concise). Thank you.
I know nothing about Drill and am curious about the similar execution times and this sentence in the report: "Spark is the second fastest, that should be reasonable, since both Spark and Drill have almost the same implementation architecture.". Is this true that Drill is Spark or vice versa under the hood? If so, how is it possible that Drill is faster? What does Drill do to make the query faster? Could this be that you used a type of query Drill is optimized for? Just guessing and am really curious (not implying that one is better or worse than the other(s)).
