Jinfeng Ni created DRILL-3765:
---------------------------------
Summary: Partition prune rule is unnecessary fired multiple times.
Key: DRILL-3765
URL: https://issues.apache.org/jira/browse/DRILL-3765
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Reporter: Jinfeng Ni
Assignee: Jinfeng Ni
It seems that the partition prune rule may be fired multiple times, even after
the first rule execution has pushed the filter into the scan operator. Since
partition prune has to build the vectors to contain the partition /file /
directory information, to invoke the partition prune rule unnecessary may lead
to big memory overhead.
Drill planner should avoid the un-necessary partition prune rule, in order to
reduce the chance of hitting OOM exception, while the partition prune rule is
executed.
