-----------------------------------
Summary: '(10 < x) IS NOT TRUE' when x is not nullable should be
simplified to '10 >= x'
Key: CALCITE-5798
URL: https://issues.apache.org/jira/browse/CALCITE-5798
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.34.0
Reporter: Runkang He
Currently '(10 < x) IS NOT TRUE' when pulled up predicates contain 'x IS NOT
NULL' is not simplified, and keep it as it is.
It can and should be simplified to '10 >= x', which is more concise and useful
for further simplification, such as CALCITE-5780
Note that this Jira is splited from CALCITE-5780, which make this part of codes
more clear.
