 Review comment:
   see `InvalidRelException` description. It should be logged at debug level.
   Is it safe to work further with null?

>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.13.0
>            Reporter: Gautam Kumar Parai
>            Assignee: Gautam Kumar Parai
>            Priority: Major
>             Fix For: 1.14.0

> Here is a sample query that may benefit from this optimization:
> SELECT * FROM T1 WHERE a1 = 5 AND a1 IN (SELECT a2 FROM T2); 
> Here the transitive predicate a2 = 5 would be pushed past the aggregate due 
> to this optimization.
