--------------------------------------
Summary: [C++] CSV reader accept schema
Key: ARROW-6536
URL: https://issues.apache.org/jira/browse/ARROW-6536
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Neal Richardson
The CSV reader lets you specify {{column_types}}, but this is an
{{unordered_map}} of column name and type. Why not accept a Schema instead?
Isn't that essentially an ordered map? Seems that if you took a Schema, some of
the validation of what's being passed in would already have been handled. Plus,
I suspect that the Datasets project will want to do even more with passing a
Schema (e.g. selecting a subset of columns).
