Chao Sun created SPARK-35361: -------------------------------- Summary: Improve performance for ApplyFunctionExpression Key: SPARK-35361 URL: https://issues.apache.org/jira/browse/SPARK-35361 Project: Spark Issue Type: Sub-task Components: SQL Affects Versions: 3.2.0 Reporter: Chao Sun

This proposes to move the call outside the loop over each input row. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
