> Key: FLINK-39313
> URL: https://issues.apache.org/jira/browse/FLINK-39313
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 2.2.0
> Reporter: Gustavo de Morais
> Assignee: Gustavo de Morais
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.3.0
>
>
> The StreamNonDeterministicUpdatePlanVisitor treats
> StreamPhysicalChangelogNormalize as transparent, never inspecting its
> filterCondition. When the optimizer pushes a WHERE clause with a
> non-deterministic function (e.g. NOW())
> into ChangelogNormalize on an upsert source, the filter asymmetrically
> drops -U records while passing +U records, corrupting the retract contract
> and causing incorrect results downstream.
