> Key: ARROW-1895
> URL: https://issues.apache.org/jira/browse/ARROW-1895
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.7.1
> Reporter: Phillip Cloud
> Assignee: Phillip Cloud
> Labels: pull-request-available
> Fix For: 0.8.0

> See the discussion here for details:
> https://github.com/pandas-dev/pandas/pull/18201
> In short we need a way to map index column names to field names in an arrow
> Table.
> Additionally, we're depending on the index columns being written at the end
> of the table and fixing this would allow us to read metadata written by other
> systems (e.g., fastparquet) that don't make this assumption.
