> Reporter: Hanoch Yang
> Priority: Blocker
>
> I find if one fragment have received records more than limit records, drill
> will not let other fragment cancel, but work unit received message, it will
> slow the query.
> case: what data i want locate in 2M region, but there is a 100M region and 2
> left 2M region. i use limit 10 to query. 4 fragement query 4 region, when one
> fragment get 10 record from 2M region, another 100M scanning fragment will
> not work. so all fragment must wait that fragment to finish scan, but it
> could have been unnecessary.
