----------------------------------
Summary: Stop query hbase region when other fragment have received
more records than LIMIT records
Key: DRILL-7962
URL: https://issues.apache.org/jira/browse/DRILL-7962
Project: Apache Drill
Issue Type: Wish
Components: Storage - HBase
Affects Versions: 1.19.0
Reporter: Hanoch Yang
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.
