Yash Datta updated SPARK-3968: ------------------------------ Shepherd: Yash Datta > Using parquet-mr filter2 api in spark sql, add a custom filter for InSet > clause > ------------------------------------------------------------------------------- > > 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 , like filtering on OPTIONAL columns as well. 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
