[jira] [Commented] (SPARK-16060) Vectorized Orc reader

    [ https://issues.apache.org/jira/browse/SPARK-16060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15937711#comment-15937711 ] 

Liang-Chi Hsieh commented on SPARK-16060:
-----------------------------------------

cc [~rxin] If the approach based on Hive package is not ok for you, shall we directly go to make presto's ORC reader work for Spark SQL?

> Currently Orc reader in Spark SQL doesn't support vectorized reading. As Hive Orc already support vectorization, we should add this support to improve Orc reading performance.
