@Value.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.
