> [Python] Provide for selecting a subset of columns to convert in
> RecordBatch/Table.from_pandas
> ----------------------------------------------------------------------------------------------

> Key: ARROW-1731
> URL: https://issues.apache.org/jira/browse/ARROW-1731
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Priority: Major
> Labels: beginner, pull-request-available
> Fix For: 0.10.0
>
>
> Currently it's all-or-nothing, and to do the subsetting in pandas incurs a
> data copy. This would enable columns (by name or index) to be selected out
> without additional data copying. We should add a {{columns=}} argument to the
> the {{from_pandas}} calls and do the subsetting when we dispatch the
> individual arrays for conversion to Arrow.
