[jira] [Updated] (SPARK-3968) Use parquet-mr filter2 api in spark
sql
[ https://issues.apache.org/jira/browse/SPARK-3968?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yash Datta updated SPARK-3968:
------------------------------
Description:
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 (will create a separate ticket for that) .
