Dongjoon Hyun updated SPARK-15958: ---------------------------------- Component/s: Spark Core > Make initial buffer size for the Sorter configurable > ---------------------------------------------------- > > Key: SPARK-15958 > URL: https://issues.apache.org/jira/browse/SPARK-15958 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.0.0 > Reporter: Sital Kedia > Assignee: Sital Kedia > Priority: Minor > Fix For: 2.1.0 > > > Currently the initial buffer size in the sorter is hard coded inside the code > (https://github.com/apache/spark/blob/master/sql/catalyst/src/main/java/org/apache/spark/sql/execution/UnsafeExternalRowSorter.java#L88) > and is too small for large workload. As a result, the sorter spends > significant time expanding the buffer size and copying the data. It would be > useful to have it configurable. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
