Gabor Szadovszky commented on PARQUET-1830:
-------------------------------------------
[~FelixKJose], agreed.
So this jira is to track the long term effort of having a vectorized API in
parquet-mr so our clients don't have to use our internal API to have fast
reading yet having our ppd filtering (including column indexes and bloom
filters) automatically executed under the hood.
> Vectorized API to support Column Index in Apache Spark
> ------------------------------------------------------
>
> 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?
