larry98 opened a new issue, #43187: URL: https://github.com/apache/arrow/issues/43187
### Describe the enhancement requested We'd like to use parquet predicate pushdown on `is_in` expressions, but this currently isn't supported in `SimplifyWithGuarantee`. We implemented a proof of concept where we sort and deduplicate the `is_in` expression's value set, then have `SimplifyWithGuarantee` binary search on the inequality bound and slice the value set accordingly. This works well, but I'm not sure what the correct interface for enabling this code path should be. Our current approach adds a new field to `SetLookupOptions` which allows the user to declare whether the value set is pre-sorted and deduplicated. Any thoughts? I'd be happy to put up a PR if we agree on an interface. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
