Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)

Fixes b/440342212.

In pandas args can be a positional argument while by_row is a keyword only argument https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.apply.html#pandas-series-apply. I would argue that we can adhere to that right now as I don't anticipate many people passing by_row positional argument, but if not, we should add an item in BigFrames 3.0 to make the breaking change.

Yeah, also thought about it. It’s difficult to fully match pandas API here so far. I have added some comments for potential breaking changes in the future. However, given that this is an edge case, I recommend we defer any such changes until there is a clear need based on user feedback.
