      @Nullable Object getFieldOrNull(RowData row)
      Converters and serializers always support nullability. The NOT NULL constraint is only considered on SQL semantic level but not data transfer. E.g. partial deletes (i.e. key-only upserts) set all non-key fields to null, regardless of logical type.
