Thanks Yufei for starting this. I'm interested and would be happy to join. My schedule is pretty much open.
I have the full UDF implementation locally and am submitting it in smaller PRs, one after another as each is merged. The first one, which adds the UDF leaf types (Representation and Parameter), is here: https://github.com/apache/iceberg/pull/15994 I'm also working on the REST APIs. The list/load function endpoints are merged (https://github.com/apache/iceberg/pull/15180), and the create/drop/exists endpoints are in review: https://github.com/apache/iceberg/pull/17966 If it helps, I can also open the whole implementation as a draft PR so reviewers can see the full picture. Reviews on these would be very helpful.
