   > Comet generates the FileScanTasks from Iceberg Java. Does Iceberg Java 
provide `unified_partition_type`, otherwise we need to be sure Comet can 
generate these if you want Comet to work with this.
   
   Good point!  Iceberg Java doesn't provide unified_partition_type on 
individual FileScanTasks — Java computes it at a higher level via 
[Partitioning.partitionType(table) 
](https://github.com/apache/iceberg/blob/main/core/src/main/java/org/apache/iceberg/Partitioning.java#L240-L244)
   
   We can do the equivalent in Comet -
