> Use parquet-mr filter2 api in spark sql
> ---------------------------------------
>
> Key: SPARK-3968
> URL: https://issues.apache.org/jira/browse/SPARK-3968
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.1.0
> Reporter: Yash Datta
> Priority: Minor
> Fix For: 1.1.1
>
>
> 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) .
