> Key: ARROW-1983
> URL: https://issues.apache.org/jira/browse/ARROW-1983
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Jim Crist
> Priority: Major
> Fix For: 0.10.0
>
>
> Currently `pyarrow.parquet` can only write the `_common_metadata` file
> (mostly just schema information). It would be useful to add the ability to
> write a `_metadata` file as well. This should include information about each
> row group in the dataset, including summary statistics. Having this summary
> file would allow filtering of row groups without needing to access each file
> beforehand.
