0.13.0
> [Python] Support reading Parquet binary/string columns as pandas Categorical
> ----------------------------------------------------------------------------
>
> Key: ARROW-3325
> URL: https://issues.apache.org/jira/browse/ARROW-3325
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Priority: Major
> Labels: parquet
> Fix For: 0.13.0
>
>
> Requires PARQUET-1324 and probably quite a bit of extra work
> Properly implementing this will require dictionary normalization across row
> groups. When reading a new row group, a fast path that compares the current
> dictionary with the prior dictionary should be used. This also needs to
> handle the case where a column chunk "fell back" to PLAIN encoding mid-stream
