Alex Levenson updated PARQUET-40:
---------------------------------
Component/s: parquet-mr
> Take advantage of dictionary pages when performing rowgroup filters in the
> filter2 API
> --------------------------------------------------------------------------------------
>
> Key: PARQUET-40
> URL: https://issues.apache.org/jira/browse/PARQUET-40
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-mr
> Reporter: Alex Levenson
> Labels: filter2
>
> We currently only filter row groups via the min / max value in the row group.
> We should additionally inspect the dictionary of unique values in a row group
> (if it has one) -- this could dramatically increase our ability to drop
> entire rowgroups.
