-----------------------------------
Attachment: (was: tables-reduced.sql)
> ExprRewriter did not rewrite 'id = 0 OR false' as expected
> -----------------------------------------------------------
>
> Key: IMPALA-13203
> URL: https://issues.apache.org/jira/browse/IMPALA-13203
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 4.4.0
> Reporter: Zihao Ye
> Assignee: Zihao Ye
> Priority: Critical
> Fix For: Impala 4.5.0
>
>
> The comments in the SimplifyConditionalsRule class mention that 'id = 0 OR
> false' would be rewritten to 'id = 0', but in reality, it does not perform
> this rewrite as expected. After executing such SQL, we can see in the text
> plan that:
> {code:sql}
> Analyzed query: SELECT * FROM functional.alltypestiny WHERE FALSE OR id =
> CAST(0
> AS INT) {code}
> The issue appears to be that the CompoundPredicate generated by
> NormalizeExprsRule was not analyzed, causing the SimplifyConditionalsRule to
> skip the rewrite.
