Review Comment:
> The mentioned examples do not cover all of that. E.g. I could not find in
the linked Trino documentation how the ordering is defined (ASC/DESC) or the
null ordering (NULLS FIRST/LAST)
I think this is a critical point, and now I am biased toward to `WRITE
ORDERED BY` + `WRITE LOCALLY ORDERED BY`(I wondered how to express LOCALLY in
the metadata of Iceberg). I am trying to talk to Trino maintainers
