    Assignee:     (was: Apache Spark)

> Reorder filter/join predicates to short-circuit isNotNull checks
> ----------------------------------------------------------------
>
>                 Key: SPARK-13668
>                 URL: https://issues.apache.org/jira/browse/SPARK-13668
>             Project: Spark
>          Issue Type: Improvement
>            Reporter: Sameer Agarwal
>
> If a filter predicate or a join condition consists of `IsNotNull` checks, we 
> should reorder these checks such that these non-nullability checks are 
> evaluated before the rest of the predicates.
> For e.g., if a filter predicate is of the form `a > 5 && isNotNull(b)`, we 
> should rewrite this as `isNotNull(b) && a > 5` during physical plan 
> generation.
