> 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.
