             Summary: Disable Parquet's record-by-record filter in normal parquet reader and do it in Spark-side
                 Key: SPARK-17310
                 URL: https://issues.apache.org/jira/browse/SPARK-17310
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Hyukjin Kwon


Currently, we are pushing filters down for normal Parquet reader which also filters record-by-record.

It seems Spark-side codegen row-by-row filtering might be faster than Parquet's one in general due to type-boxing and virtual function calls which Spark's one tries to avoid.

Maybe we should perform a benchmark and disable this. This ticket was from https://github.com/apache/spark/pull/14671

Please refer the discussion in the PR.
