**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `RowSelection::intersection` already exists for computing the intersection of two `RowSelection`s. This is useful when you have a filter predicate that filters on two columns that have been AND'ed together and need the intersection of the RowSelection of each side of the AND. Correspondingly, if you have a filter that is `A OR B` rather than `A AND B`, it is desirable to derive the union of the row selections of A and B. Therefore I propose that `RowSelection::union` be added as a feature, to complement `RowSelection::intersection`. **Describe the solution you'd like** https://github.com/apache/arrow-rs/issues/3003 introduced `RowSelection::intersection`, for which https://github.com/apache/arrow-rs/pull/3047 was submitted and merged. I will shortly be submitting a similar PR for `RowSelection::union`. **Describe alternatives you've considered** None **Additional context** I have a PR open on iceberg-rust, where I am using `RowSelection::intersection` but needed to implement a `RowSelection` union function myself. I think it makes more sense for it to live in here alongside `intersection` where others can make use of it too. -- This is an automated message from the Apache Git Service.
