Michael Styles updated SPARK-17091:
-----------------------------------
Summary: Convert IN predicate to equivalent Parquet filter (was:
ParquetFilters rewrite IN to OR of Eq)
> Convert IN predicate to equivalent Parquet filter
> -------------------------------------------------
>
> Key: SPARK-17091
> URL: https://issues.apache.org/jira/browse/SPARK-17091
> Project: Spark
> Issue Type: Bug
> Reporter: Andrew Duffy
> Attachments: IN Predicate.png, OR Predicate.png
>
>
> Past attempts at pushing down the InSet operation for Parquet relied on
> user-defined predicates. It would be simpler to rewrite an IN clause into the
> corresponding OR union of a set of equality conditions.
