能不能看一下 tidb.log ，关键字 nontransactional.go 类似这样的日志，有没有出现边界重复。
tidb.log 日志例举如下：
[2022/12/30 09:45:53.436 +08:00] [INFO] [nontransactional.go:423] [“start a Non-transactional DML”] [conn=3074535777447707195] [job=“job id: 1, estimated size: 1000, sql: INSERT INTO `test_order`.`test_order_target` SELECT * FROM `test_order`.`test_order` WHERE `id` BETWEEN 5 AND 100902”] [totalJobCount=30319]
