之前的分类器就不太适用，这里就要介绍一个叫做决策树RGHB个人化

正常情况下，OGG遇到异常报错，导致OGG进程中断Time Since Chkpt 50个小时后，解决报错后，启动该进程，一般来说2分内，会执行成功最少一个事务，会写入新的检查点，延迟的50个小时，会自动转换为lag at chkpt 50小时延迟。

异常情况或者说需要优化调整的情况是，启动进程，发现time since chkpt 延迟一直递增，不减少。说明存在事务未执行完毕。
实际遇到的情况1，进程同步4个表，其中一个表很大10G，并且目标端无主键！！！

因此目标端执行一条update sql执行效率非常低。 如何处理？？？
