   > Thanks @adriangb for pinging me, in Comet we would need to adapt to the 
changes, if I understood the changes we would need to use `CastExpr` instead of 
`CastColumnExpr` ?
   
   Yes I just checked and it seems like you’re actually using neither. 
Searching the codebase for `CastColumnExpr` all I found was your custom 
implementation: 
https://github.com/apache/datafusion-comet/blob/88c1ffcd083eb05bcbdcc85090e53b3398850946/native/core/src/parquet/cast_column.rs#L181.
 Now that `CastExpr` is more capable maybe you can just use that?
   
   You do use `CastExpr` but that shouldn’t change:
