> [C++] CSV Add byte offset for error messages
> --------------------------------------------
>
> Key: ARROW-13252
> URL: https://issues.apache.org/jira/browse/ARROW-13252
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Nate Clark

> Priority: Major

>
> CSV parsing error messages will contain the row number when parallel parsing
> is not enabled but when parallel parsing is enabled there is no indication of
> where the error occurred in the input. In order to add that context the row
> byte offset can be added to the output.
>
> This can be done relatively easily for the parser but associating byte
> offsets with the data or row being decoded would require more metadata to be
> maintained in the DataBatch. Potentially doubling the size of ParsedValueDesc.
>
> This was mentioned and discussed in comments
