> Add a UUID type that is physically represented as an 128bit fixed sized binary. The addition of the type should add the annotation that a value in this column is a UUID. The important benefit would be that in the native language object models we could return the respective UUID class, e.g. {{java.util.UUID}} in Java and {{uuid.UUID}} in Python. For reference, Postgres and Parquet both have a UUID type as well do other data system have this small specialization.
