Nick White created ARROW-1689:
---------------------------------

             Summary: [Python] Categorical Indices Should Be Zero-Copy
                 Key: ARROW-1689
                 URL: https://issues.apache.org/jira/browse/ARROW-1689
             Project: Apache Arrow
          Issue Type: Improvement

It seems like [WriteIndices|https://github.com/apache/arrow/blob/0c8b861f93884f2868eb631d8fceee3a8b8905ec/cpp/src/arrow/python/arrow_to_pandas.cc#L955-L981] could reuse some of the logic in [ConvertValuesZeroCopy|https://github.com/apache/arrow/blob/0c8b861f93884f2868eb631d8fceee3a8b8905ec/cpp/src/arrow/python/arrow_to_pandas.cc#L1348-L1385] to avoid copying the integer indices array?
