[Feature request] Raise NotImplementedError for specification of unused batch_size in DataFrame.read

[jggatter]

Hi team!

I noticed my editor was displaying batch_size in the function signature pop-up for DataFrame.read. After testing it a few times I wasn't sure if it was doing anything, so I took a peek and noticed that the param is immediately deleted as it is currently unused!

Until the parameter affects the behavior of the function, when a user passes a non-default value, would the team be able to raise a NotImplementedError or notify the user that it lacks of effect?

Negligible priority.

Thanks,
James
