@Enclosing public class SimplifyJoinConditionRule extends org.apache.calcite.plan.RelRule<SimplifyJoinConditionRule.SimplifyJoinConditionRuleConfig>
Planner rule that apply various simplifying transformations on join condition. e.g. reduce same expressions: a=b AND b=a -> a=b, simplify boolean expressions: x = 1 AND FALSE -> FALSE, simplify cast expressions: CAST('123' as integer) -> 123
