Antoine Pitrou resolved ARROW-1731. ----------------------------------- Resolution: Fixed Issue resolved by pull request 1924 [https://github.com/apache/arrow/pull/1924] > [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. > cc [~cpcloud] [~jreback] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
