> Key: FLINK-11310
> URL: https://issues.apache.org/jira/browse/FLINK-11310

> Issue Type: Improvement

> In FLINK-10474, we force translate IN into a predicate to avoid translating
> to a JOIN. In addition, we add a Rule to convert the predicates back to IN so
> that we can generate code using a HashSet for the IN.
> However, FLINK-10474 only takes Filter into consideration. It would be great
> to also convert predicates in Project to IN. It not only will improve the
> performance for the Project, but also will avoid the problem raised in
> FLINK-11308, as all predicates will be converted into one IN expression.
