There was a problem hiding this comment.
Awesome! Looks good
There is another type of nested schema in Arrow, though: ListVector. I mentioned it in a related issue: #1256. If we close the current issues, we should probably create a new issue for this type after this one. It would also allow us to do FrameColumn <-> List[Struct], for instance :)

Yes, let's do ListVector too. It's mentioned in #271 that won't be closed by this PR |
