Subject [jira] [Updated] (SPARK-3968) Use parquet-mr filter2 api in spark sql
Date Sat, 18 Oct 2014 13:19:33 GMT

     [ 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 . 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) .
