> ArrayData specialization to enable RowEncoder primitive arrays support
> ----------------------------------------------------------------------
>
> Key: SPARK-33689
> URL: https://issues.apache.org/jira/browse/SPARK-33689
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.1
> Reporter: Artem Kupchinskiy
> Priority: Major
>
> Currently, even non-nullable array fields are represented as
> WrappedArray.ofRef in external rows. It leads to memory footprint, as well as
> unnecessary cycles in boxing/unboxing operations. Ideally, if arrays are
> non-nullable and contain primitive values, they should be represented as
> specialized less-overhead versions of WrappedArray.
