I understand more about what CALCITE-3192 does. > Enhance RexSimplify to simplify 'a>1 or (a<3 and b)' to 'a>1 or b' if column > a is not nullable > ---------------------------------------------------------------------------------------------- > > Key: CALCITE-3803 > URL: https://issues.apache.org/jira/browse/CALCITE-3803 > Project: Calcite > Issue Type: Improvement > Components: core > Reporter: Chunwei Lei > Assignee: Chunwei Lei > Priority: Major > > For {{a>1 or (a<3 and b)}}, with short-circuit, we know {{a<=1}} if {{a>1}} > is false when column a is not nullable.
