Sital Kedia created SPARK-15958: ----------------------------------- Summary: Make initial buffer size for the Sorter configurable Key: SPARK-15958 URL: https://issues.apache.org/jira/browse/SPARK-15958 Project: Spark Issue Type: Bug Affects Versions: 2.0.0 Reporter: Sital Kedia
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
