---------------------------------------
Summary: [C++] csv::TableReader column names, Read() arguments
Key: ARROW-10219
URL: https://issues.apache.org/jira/browse/ARROW-10219
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Neal Richardson
Fix For: 3.0.0
Some feature requests:
* csv::TableReader {{column_names}} method, and/or {{schema}} method. This will
(in most cases) require IO to get these from the file, but that's fine. There
are use cases (we've seen in R) where it would help to be able to get the names
from the file (e.g. when you specify column types, it's a map of column name to
type, so you can't currently specify types without also specifying names)
* Add Read(std::vector<int>) like how feather (and parquet?) have so that you
don't have to parse and allocate columns you don't want.
