> Skip runtime filter for outer joins when Expr not constant after null

> Key: IMPALA-10593
> URL: https://issues.apache.org/jira/browse/IMPALA-10593
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Steve Carlin
> Assignee: Stephen Carlin
> Priority: Minor
>
> Currently there is code that asserts that an Expr is not constant after
> substituting SlotRefs with constant nulls.
> A third party tool needs this restriction to be weakened. In a case where an
> Expr is checked and the Expr is not constant even after substituting nulls,
> the result will be to not generate a runtime filter for that Expr.
