------------------------------------
Summary: 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
Reporter: Alex Levenson
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.
