> Remove InSet filter pushdown from Parquet
> -----------------------------------------
>
> Key: SPARK-16400
> URL: https://issues.apache.org/jira/browse/SPARK-16400
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Reynold Xin
>
> Filter pushdown that needs to be evaluated per row is not useful to Spark,
> since parquet-mr own filtering is likely to be less performant than Spark's
> due to boxing and virtual function dispatches.
> To simplify the code base, we should remove the InSet filters.
