Alessandro Molina updated ARROW-10219: -------------------------------------- Fix Version/s: (was: 5.0.0) 6.0.0 > [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 > Assignee: Weston Pace > Priority: Major > Fix For: 6.0.0 > > > 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. > cc [~apitrou] [~romainfrancois] -- This message was sent by Atlassian Jira (v8.3.4#803005)
