> ------------------------------------------------------------
>
> Key: HIVE-28202
> URL: https://issues.apache.org/jira/browse/HIVE-28202
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 4.0.0-beta-1, 4.0.0
> Reporter: Denys Kuzmenko
> Assignee: Denys Kuzmenko
> Priority: Critical
> Labels: hive-4.0.1-must, performance
> Fix For: 4.1.0
>
>
> `ReaderImpl.getRawDataSizeFromColIndices` changed behavior for handling
> struct type and now includes their subtypes. That caused an issue in Hive as
> the root struct index is always "included", causing size estimation for the
> complete schema, not just selected columns leading to incorrect split
> estimations.
