通过qlib源码看,update时,只会更新比上次时间段多出来的时间,如果没有多出来时间,则不会做任何处理(即便特征集合不一样). 比如上次是0801-0820,这次是0728-0824,则只会将0821-0824的数据进行更新处理.就算是0728-0731区间的数据的都不会处理的. 你这个两次时间截止日期一模一样,所以不会做任何处理. 你这里应该用dump_fix

按照你的描述,2002年0801到2022年0801第一次使用dump_all,然后更新0802到0820,这是新增数据,因此你用update为何会有问题呢?为何又用fix 了呢? 最开始你的描述是因为你时间上重叠了,所以我回复的update没效果,只能用fix。 但是之后你的回复,时间上是不相同的,update会有效果,不需要用fix
