   In the [example](https://github.com/apache/iceberg/issues/2270#issuecomment-786255694) above, I'd imagine Spark would load defaults from the session config, combine it with properties provided in the create table statement and pass to the catalog implementation. Meaning we would get a map with `k1 -> v1` (comes from the session conf) and `k2 -> custom_value` (comes from the statement directly), which will be persistent in the metadata.
   
   The idea of not persisting props and simply overriding at runtime seems interesting but it will be way harder to implement, I guess.
