--------------------------------------
Can you show some pseudo codes? It's a bit difficult to follow what the JIRA
targets.
> class 'DataFrame' returns instance of type(self) instead of DataFrame
> ----------------------------------------------------------------------

> Key: SPARK-32423
> URL: https://issues.apache.org/jira/browse/SPARK-32423
> Project: Spark
> Issue Type: Wish
> Components: PySpark
> Affects Versions: 2.4.6, 3.0.0
> Reporter: Timothy
> Priority: Minor
>
> To allow for appropriate child classing of DataFrame, I propose the following
> change:
> class 'DataFrame' returns instance of type(self) instead of typeDataFrame
>
> Therefore child classes using methods such as '.limit()' will return an
> instance of the child class.
