> In {{FileSinkOperator}}, a serializer is created to write output data. When
> initializing it we should not read the
> {{ColumnProjectionUtils.READ_NESTED_COLUMN_PATH_CONF_STR}} property since
> this is only used for the read path, and the path may not match the schema
> for the output table (for instance, in the case of insert).
