It sounds like the "span" type could be implemented as a composite of
multiple Arrow arrays / schemas:
array 1 (data)
array 2 (view)
Unless I'm missing something, this feels like an application-level
concern rather than something that needs to be addressed in the
columnar format / metadata.
Well, couldn't the same theoretically be said about list arrays?
In the end, I suppose it all depends whether there's enough demand to
make it a core logical type inside Arrow, rather than something people
write custom code for in their application.
