> GetRecordBatchReader() should
> "Return a RecordBatchReader of row groups selected from row_group_indices, the
> ordering in row_group_indices matters." (that is what the doxygen string
> says),
> *but:*
> Since change ARROW-1012, it ignores the {{row_group_indices}} argument.
> The {{row_group_indices_}} in the {{RowGroupRecordBatchReader}} that is
> created are never used.
> Either the documentation should be changed, or the behavior should be
> reverted. I would prefer the latter, as I do not know how to make sure to
> read a specific row groups anymore...
