> Memory leaks in ParquetColumnVector
> -----------------------------------
>
> Key: SPARK-60098
> URL: https://issues.apache.org/jira/browse/SPARK-60098
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Filipe Oliveira
> Priority: Minor
>
> introduced the ParquetColumnVector class and alongside it 2 column vectors:
> `repetitionLevels` and `definitionLevels`. These vectors are allocated by the
> class but never closed.
>
> Meanwhile, other PRs have changed this class and also allocated column
> vectors but did not close them:
> * [https://github.com/apache/spark/pull/52557]
> * [https://github.com/apache/spark/pull/48851]
>
> When using OFF_HEAP mode these vectors will lead to memory leaks.
