> The problem with {{FieldsDataType}} is that the method {{getFieldDataTypes}}
> does not keep the order of the fields stored in the logical type. Therefore
> at couple of locations we have to first iterate over the names in logical
> type and then get the DataTypes.
> {code}
> final RowType rowType = (RowType) fieldsDataType.getLogicalType();
> final String[] fieldNames = rowType.getFields()
> .stream()
> .map(RowType.RowField::getName)
> .toArray(String[]::new);
> final TypeInformation<?>[] fieldTypes = Stream.of(fieldNames)
> .map(name -> fieldsDataType.getFieldDataTypes().get(name))
> .map(LegacyTypeInfoDataTypeConverter::toLegacyTypeInfo)
> .toArray(TypeInformation[]::new);
> {code}
