…make sure rewrite result stable (apache#43785) The result of successful rewriting by the cbo optimizer depends on the statistics. The priority of the optimizer consumption statistics in descending order is 1. the injected statistics 2. the statistics reported by be 3. and the statistics analyzed actively. When the pipeline runs the case, the statistics reported by be may not be timely. Therefore, the outcome that leads to the cbo optimizer's successful selection of overwrites is not very certain, so the statistics are currently injected manually in the test cases
