Why I'm doing:
What I'm doing:
in this pr, I support expression reuse strategy on outer join's where predicates, just like what we do in scan predicates(#52889).
currently, this optimization applies to hash/nest loop outer joins.
For inner joins, both where and on predicates appear in the PhysicalJoinOperator's onPredicate , rather than predicates . I'm concerned that splitting the onPredicate clause might introduce additional risks, so I didn't do it in this pr, we can support this in the future if needed.
