-------------------------------------
seems it's already fixed?
> Share a single Row for CSV data source rather than creating every time

> Currently, CSV data source is creating each Row.
> Single row can be shared just like the other data sources.
> It is a bit not related but it might be great if some improvements were made
> in term of performances. This was suggested in
> https://github.com/apache/spark/pull/12268.
