Hi all, I'm trying to propose the metadata change for variant shredding in ( https://docs.google.com/document/d/1gAvt0x_ez89O8y-YqkCdMnTEykb-583YslYOgzf5sPg/edit?tab=t.0) and https://github.com/apache/iceberg/issues/11958.
Basically, in Iceberg format V3, we collect subcolumn lower/upper bounds into a variant value and then serialize it into binary. There will be no manifest format change. Can you please help take a look at this? Thanks, Aihua
