> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.34.0
> Reporter: Runkang He
> Assignee: Runkang He
> Priority: Major
> Labels: pull-request-available
>
> Currently '(1 < x) IS NOT TRUE' when pulled up predicates contain 'x IS NOT
> NULL' is not simplified, and keeps it as it is.
>
> It can and should be simplified to '1 >= x', which is more concise and useful
> for further simplification, such as CALCITE-5780
>
> Note that this Jira is splited from CALCITE-5780, which makes this part of
> codes more clear, and follows the principle that a Jira only discusses one
> issue.
