Shant Hovsepian commented on IMPALA-9470:
-----------------------------------------
It would be nice but not required to support pushing runtime bloom filters down
to parquet bloom filters if the bloom filter bitmaps can be made compatible.
> Use Parquet bloom filters

> Key: IMPALA-9470
> URL: https://issues.apache.org/jira/browse/IMPALA-9470
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Zoltán Borók-Nagy
> Priority: Major
>
> PARQUET-41 has been closed recently. This means Parquet-MR is capable of
> writing and reading bloom filters.
> Currently bloom filters are per column chunk entries, i.e. with their help we
> can filter out entire row groups.
> We already filter row groups in HdfsParquetScanner::NextRowGroup() based on
> column chunk statistics and dictionaries. Skipping row groups based on bloom
> filters could be also added to this funciton.
> Impala could also write bloom filters.
