What is "large numbers of files"? 50? 100? I see it happens at 1000. That is not large numbers of files.

> query like select * from `/drill/data` limit 100 takes quite long to terminate, about 20+ seconds.
> /drill/data includes overall 1100 csv files, all in single directory.
> select * from `/drill/data/d2.csv` limit 100; terminates in 0.2 seconds.
