SPARK-3968 Use parquet-mr filter2 api in spark sql The parquet-mr project has introduced a new filter api (https://github.com/apache/incubator-parquet-mr/pull/4), 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 You can merge this pull request into a Git repository by running: $ git pull https://github.com/saucam/spark master Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/2841.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #2841 ---- commit 0bc54d3c0384606886a3e297cfdc85f44e2ea7e9 Author: Yash Datta <yash.da...@guavus.com> Date: 2014-10-16T12:15:21Z SPARK-3968: Change parquet filter pushdown to use filter2 api of parquet-mr commit 6adaf9b33f07ed247643ddf14020db69ece9d4fb Author: Yash Datta <yash.da...@guavus.com> Date: 2014-10-18T13:15:45Z SPARK-3968: Not pushing the filters in case of OPTIONAL columns ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
