[jira] [Commented] (SPARK-37034) What's the progress of vectorized execution for spark?
[ https://issues.apache.org/jira/browse/SPARK-37034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17437213#comment-17437213 ] xiaoli commented on SPARK-37034: [~cloud_fan] Thanks very much. The hint in your answer helps me find ApplyColumnarRulesAndInsertTransitions class in spark, I could do more investigation now. > What's the progress of vectorized execution for spark? > -- > > Key: SPARK-37034 > URL: https://issues.apache.org/jira/browse/SPARK-37034 > Project: Spark > Issue Type: New Feature > Components: Spark Core >Affects Versions: 3.2.0 >Reporter: xiaoli >Priority: Major > > Spark has support vectorized read for ORC and parquet.

Please ask it in the dev-list instead of JIRA. A quick answer is: there is no plan to add vectorized execution into Spark in the near future, but there are third-party libraries doing it via the columnar API in the Spark query plan. > What's the progress of vectorized execution for spark? > -- > > Key: SPARK-37034 > URL: https://issues.apache.org/jira/browse/SPARK-37034 > Project: Spark > Issue Type: New Feature > Components: Spark Core >Affects Versions: 3.2.0 >Reporter: xiaoli >Priority: Major > > Spark has support vectorized read for ORC and parquet.

All of you have contribute to spark's vectorized read, so I guess you may know something about this question.
