Subject query performance with unequal drillbits
Date Tue, 21 Aug 2018 20:48:04 GMT
Hi community,
I am trying to find a way to tune Drill so that weaker drillbits get less
data to work on so that the weak link doesn't drag my performance down. I
have drillbits running on a variety of hardware and sometimes these shared
resources get really slow. It seems that the query plan always evenly
divides the data fragments so that each drillbit gets the same data to chew
on. How do I make it give weaker drillbits less data?

Alternatively, is there a way to limit and queue fragments of the query and
leave them unassigned, then assign to drillbits as their resources become
free, similar to MapReduce?

Thanks for you time,
Scott
