holdenk opened a new pull request, #52950: URL: https://github.com/apache/spark/pull/52950
### What changes were proposed in this pull request? We plumb through non-determinism information, as with nullability, from projection to union. WIP: I need to double check the other set operations. ### Why are the changes needed? We need to be careful pushing through non-deterministic components & other changes. ### Does this PR introduce _any_ user-facing change? Yes, the attribute reference now has a determinism field. For backwards compat, unpack does not unpack that field, and it has a default value. ### How was this patch tested? Added a test in the filter pushdown logic. ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
