We can't avoid OOM.
> DS V2 Limit push-down should avoid out of memory
> ------------------------------------------------
>
> Key: SPARK-39065
> URL: https://issues.apache.org/jira/browse/SPARK-39065
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: jiaan.geng
> Priority: Major
>
> Currently, Spark DS V2 supports push down Limit operator to data source.
> But the behavior only controlled by pushDownList option.
> If the limit is very large, then Executor will pull all the result set from
> data source.
> So it will cause the memory issue as you know.
