> [PYTHON] serialize_pandas roundtrip loses columns name
> ------------------------------------------------------
>
> Key: ARROW-1586
> URL: https://issues.apache.org/jira/browse/ARROW-1586
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.7.0
> Reporter: Tom Augspurger
> Assignee: Phillip Cloud
> Priority: Minor
> Labels: pull-request-available
> Fix For: 0.8.0
>
>
> The serialize / deserialize roundtrip loses {{ df.columns.name }}
> {code:python}
> In [1]: import pandas as pd
> In [2]: import pyarrow as pa
> In [3]: df = pd.DataFrame([[1, 2]], columns=pd.Index(['a', 'b'],
> name='col_name'))
> In [4]: df.columns.name
> Out[4]: 'col_name'
> In [5]: pa.deserialize_pandas(pa.serialize_pandas(df)).columns.name
> {code}
> Is this in scope for pyarrow? I suspect it would require an update to the
> pandas section of the Schema metadata.
