Can I add a new column without rewriting an entire file?

I've been experimenting with Apache Arrow. I have used the column oriented memory mapped files for many years. In the past, I've used a separate file for each column. Arrow seems to like to store everything in one file. Is there a way to add a new column without rewriting the entire file?
