------------------------------
External issue URL: https://github.com/apache/arrow/issues/21421
> [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
> Components: C++, Python
> Affects Versions: 0.12.1
> Reporter: Philipp Moritz
> Assignee: Ben Kietzman
> Priority: Major
> Labels: csv, pull-request-available
> Fix For: 0.14.0
>
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> 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?
