   I work with spark 3 and find Iceberg a great tool, but I have some complex UDF which calculate my partitions from the id column.
   do iceberg has an API to say iceberg use my UDF in the same way as bucket or truncate, to hide partitioning calculation?
   For now, I just create a custom physical optimization rule, which actually applies my UDF to a column in case this column is part of where clause or merge clause. But I have doubt that this is a good way, look like a hack.
