@Enclosing public class FlinkJoinReorderRule extends org.apache.calcite.plan.RelRule<FlinkJoinReorderRule.Config> implements org.apache.calcite.rel.rules.TransformationRule
Flink join reorder rule, which can change the join order of input relNode tree.

It is triggered by the (MultiJoin).

In this rule, there are two specific join reorder strategies can be chosen, one is LoptOptimizeJoinRule, another is FlinkBushyJoinReorderRule. Which rule is selected depends on the parameter OptimizerConfigOptions.TABLE_OPTIMIZER_BUSHY_JOIN_REORDER_THRESHOLD.
