Neal Richardson created ARROW-6536: -------------------------------------- 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).
