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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
