> The parquet-mr project has introduced a new filter api , along with several fixes . It can also eliminate entire RowGroups depending on certain statistics like min/max
> We can leverage that to further improve performance of queries with filters.
> Also filter2 api introduces ability to create custom filters. We can create a custom filter for the optimized In clause (InSet) , so that elimination happens in the ParquetRecordReader itself (will create a separate ticket for that) .
