Antoine Pitrou commented on ARROW-4912: --------------------------------------- If there's no way to change column names post-hoc, then perhaps we should just add one? That sounds more universal than adding ad hoc options to the CSV reader. As for the header_rows=0, can you open a separate issue? > [C++, Python] Allow specifying column names to CSV reader > --------------------------------------------------------- > > Key: ARROW-4912 > URL: https://issues.apache.org/jira/browse/ARROW-4912 > Project: Apache Arrow > Issue Type: Improvement > Components: C++, Python > Affects Versions: 0.12.1 > Reporter: Philipp Moritz > Priority: Major > Labels: csv > > Currently I think there is no way to specify custom column names for CSV > files. It's possible to specify the full schema of the file, but not just > column names. > See the related discussion here: ARROW-3722 > The goal of this is to re-use the CSV type-inference but still allow people > to specify custom names for the columns. As far as I know, there is currently > no way to set column names post-hoc, so we should provide a way to specify > them before reading the file. > Related to this, ParseOptions(header_rows=0) is not currently implemented. > Is there any current way to do this or does this need to be implmented? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
