Good afternoon, I wanted to reach out and open a dialog about structs, the
evolution of them in schemas, and if support for such a feature is on the
road map or a hard pass for the arrow team.

Currently, it appears structs support removing a field, but will there be
support for adding fields later on? Are there any recommended patterns for
supporting such a field. For example, if a field foo is a struct with
sub_fields A, B and then later field C gets added, the old data can not be
loaded using the new schema.

Thank you.

Matthew Scanlon
