Sorabh Hamirwasia resolved DRILL-6678. -------------------------------------- Resolution: Fixed > Improve SelectionVectorRemover to pack output batch based on BatchSizing > ------------------------------------------------------------------------ > > Key: DRILL-6678 > URL: https://issues.apache.org/jira/browse/DRILL-6678 > Project: Apache Drill > Issue Type: Improvement > Components: Execution - Relational Operators > Affects Versions: 1.14.0 > Reporter: Sorabh Hamirwasia > Assignee: Sorabh Hamirwasia > Priority: Major > Labels: ready-to-commit > > SelectionVectorRemover in most of the cases is downstream to Filter which > reduces the number of records to be copied in output container. In those > cases if SelectionVectorRemover can pack the output batch to maximum > utilization that will reduce the number of output batches from it and will > help to improve performance. During Lateral & Unnest Performance evaluation > we have noticed a significant decrease in performance as number of batches > increases for same number of rows (i.e. Batch is not fully packed) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
