   @kosiew the root cause of the issue is how arrow writer handles data for 
`Dictionary(Decimal)`, and I suppose it'll mostly be fixed by 
https://github.com/apache/arrow-rs/pull/6987
   
   Regarding RG pruning not being enabled in case literal and column have 
different datatypes -- I think adding some safe casting to enable it would be a 
useful feature. For this, perhaps, 
[PruningPredicate](https://github.com/apache/datafusion/blob/main/datafusion/physical-optimizer/src/pruning.rs#L529)
 and its interactions with ParquetExec will be a good place to start dig in.
