-------------------------------------
Summary: [C++, Python] Allow specifying column names to CSV reader
Key: ARROW-4912
URL: https://issues.apache.org/jira/browse/ARROW-4912
Project: Apache Arrow
Issue Type: Improvement
Reporter: Philipp Moritz
Currently I think there is no way to specify custom column names for CSV files.
It's possible to specify the full schema of the file, but not just column names.
See the related discussion here: ARROW-3722
The goal of this is to re-use the CSV type-inference but still allow people to
specify custom names for the columns. As far as I know, there is currently no
way to set column names post-hoc, so we should provide a way to specify them
before reading the file.
Related to this, ParseOptions(header_rows=0) is not currently implemented.
Is there any current way to do this or does this need to be implmented?
