----------------------------------------------

Wouldn't that tell something about internal fragmentation in allocator? And 
accordingly tune the min allocation size..

> LLAP: output QueryFragmentCounters somewhere

> Right now, LLAP logs counters for every fragment; most of them are IO related 
> and could be very useful, they also include table names so that things like 
> cache hit ratio, etc., could be calculated for every table.
> We need to output them to some metrics system (preserving the breakdown by 
> table, possibly also adding query ID or even stage) so that they'd be usable 
> without grep/sed/awk.
