[jira] [Commented] (PARQUET-1830) Vectorized API to support Column
Index in Apache Spark
[ https://issues.apache.org/jira/browse/PARQUET-1830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17161573#comment-17161573 ]

--------------------------------------
[~FelixKJose]Do we have Spark task created for implementing the short term solution?

> Key: PARQUET-1830
> URL: https://issues.apache.org/jira/browse/PARQUET-1830
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-mr
> Affects Versions: 1.11.0
> Reporter: Felix Kizhakkel Jose
> Priority: Major
>
> As per the comment on https://issues.apache.org/jira/browse/SPARK-26345. Its seems like Apache Spark doesn't support Column Index until we disable vectorizedReader in Spark - which will have other performance implications. As per [~zi] , parquet-mr should implement a Vectorized API. Is it already implemented or any pull request for the same?
