Wes McKinney commented on ARROW-1796:
-------------------------------------
Since we're on a critical path to get 0.11 out in the next week or two, I'm
moving this to 0.12
> [Python] RowGroup filtering on file level
> -----------------------------------------
>
> Key: ARROW-1796
> URL: https://issues.apache.org/jira/browse/ARROW-1796
> Project: Apache Arrow
> Issue Type: Improvement
> Reporter: Uwe L. Korn
> Assignee: Uwe L. Korn
> Priority: Major
> Fix For: 0.12.0
>
>
> We can build upon the API defined in {{fastparquet}} for defining RowGroup
> filters:
> https://github.com/dask/fastparquet/blob/master/fastparquet/api.py#L296-L300
> and translate them into the C++ enums we will define in
> https://issues.apache.org/jira/browse/PARQUET-1158 . This should enable us to
> provide the user with a simple predicate pushdown API that we can extend in
> the background from RowGroup to Page level later on.
