Yash Datta created SPARK-3968: --------------------------------- Summary: 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
