[jira] [Commented] (SPARK-12918) Support R SQL UDF in SparkR

    [ https://issues.apache.org/jira/browse/SPARK-12918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15108110#comment-15108110 ] 

Sun Rui commented on SPARK-12918:
---------------------------------

Spark is now supporting vectorized execution via Columnar batch. See SPARK-12785 and SPARK-12635. Hope this could benefit SparkR UDF.
