What is the problem the feature request solves?

Arrow plans to remove dict_id from the Field struct. See apache/arrow-rs#5981 for more information.

It seems that Comet currently relies on using this dict_id to track dictionaries during FFI between Rust and JVM and removing it may require changes in Comet.

This ticket is for investigating this issue more.
