Antoine Pitrou commented on ARROW-14578:
----------------------------------------

> The documentation for Dense union contains "Critically, the dense union allows for minimal overhead in the ubiquitous union-of-structs with non-overlapping-fields use case (``Union<s1: Struct1, s2: Struct2, s3: Struct3, ...>``)" which is incorrect and should be moved to the doc for sparse union.
