   @tristaZero I'm working on the optimizer in this [repo](https://github.com/guimingyue/shardingsphere) forked from apache shardingsphere. And I add an optimizer entrance class named [DefaultPlanner](https://github.com/guimingyue/shardingsphere/blob/65149fd329d343dcb7bf711fe63b02043e802e8e/shardingsphere-infra/shardingsphere-infra-optimize/src/main/java/org/apache/shardingsphere/infra/optimize/planner/DefaultPlanner.java). As many other optimizer, there is also a class containing a collection of rules. In this project, this class is [PlannerRules](https://github.com/guimingyue/shardingsphere/blob/65149fd329d343dcb7bf711fe63b02043e802e8e/shardingsphere-infra/shardingsphere-infra-optimize/src/main/java/org/apache/shardingsphere/infra/optimize/planner/PlannerRules.java)
