Aman Sinha commented on DRILL-3765: ----------------------------------- [~jni] I did not realize this was assigned to me for review...will do that soon. > 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: Aman Sinha > > 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)
