[jira] [Updated] (ARROW-12970) [Python] Efficient "row accessor"
for a pyarrow Table
[ https://issues.apache.org/jira/browse/ARROW-12970?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joris Van den Bossche updated ARROW-12970:
------------------------------------------
Summary: [Python] Efficient "row accessor" for a pyarrow Table (was: [Python] efficient "row accessor" for a pyarrow Table)
> [Python] Efficient "row accessor" for a pyarrow Table
> -----------------------------------------------------

> Key: ARROW-12970
> URL: https://issues.apache.org/jira/browse/ARROW-12970
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Reporter: Luke Higgins
> Priority: Minor
>
> It would be nice to have a nice row accessor for a Table akin to pandas.DataFrame.itertuples.
> I have a lot of code where I am converting a parquet file to pandas just to have access to the rows through iterating with itertuples. Having this ability in pyarrow natively would be a nice feature and would avoid memory copy in the pandas conversion.
