> 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
> Fix For: 2.3.0
>
>
> 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.
