> URL: https://issues.apache.org/jira/browse/FLINK-31466
> Project: Flink
> Issue Type: Improvement
> Reporter: Sergey Nuyanzin
> Assignee: Sergey Nuyanzin
> Priority: Major
> Labels: pull-request-available
>
> In https://issues.apache.org/jira/browse/CALCITE-4499 there has been done an
> optimization.
> Since Flink has it's own copy of slightly changed {{FilterJoiRule}} this
> optimization does not come with 1.28 update.
> The idea is to apply this change to {{FlinkFilterJoinRule}}
