Every query engine has its expression framework to prune files. The current `Predicate` in `iceberg-rust` is very simple, it's not powerful yet. For example, it does not support Cast Expression and other complex expression. such as: filter = `abs( cast(id2 as int) ) > id2` Though this filter is rarely used, query engine can make its own effort to calculate the domain based on the stats (Such as ConstantFolder framework in [databend](https://github.com/datafuselabs/databend/blob/12c70e7c13b0466b5e7134e6872e23697975a6a8/src/query/storages/common/index/src/range_index.rs)) -- This is an automated message from the Apache Git Service.
