I think you meant reverse in the function name rather than reserve?

DataFusion expressions and Iceberg predicates do not have a one-to-one correspondence.
Exprin DataFusion, whereas they are merely components of predicates in Iceberg.AndandOrare operators in DataFusion, but they are treated as predicates in Iceberg.This disparity complicates the transformation process when using
TreeNode. To address this, I also refactored the code to simplify it.
