> Key: ARROW-1593
> URL: https://issues.apache.org/jira/browse/ARROW-1593
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.7.0
> Reporter: Tom Augspurger
> Assignee: Wes McKinney
> Priority: Minor
> Labels: pull-request-available
> Fix For: 0.8.0

> I'm doing some benchmarking of Arrow serialization for dask.distributed to
> serialize dataframes.
> Overall things look good compared to the current implementation (using
> pickle). The biggest difference was pickle's ability to use pandas'
> RangeIndex to avoid serializing the entire Index of values when possible.
> I suspect that a "range type" isn't in scope for arrow, but in the meantime
> applications using Arrow could detect the `RangeIndex`, and pass {{
> pyarrow.serialize_pandas(df, preserve_index=False) }}
