Martin created ARROW-6005:
-----------------------------
Summary: arrow::FileReader::GetRecordBatchReader() does not behave
as documented since ARROW-1012
Key: ARROW-6005
URL: https://issues.apache.org/jira/browse/ARROW-6005
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 0.14.1, 0.14.0
Reporter: Martin
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...
