确实应该这样设计, 不过现在一旦改动, 历史版本貌似没法兼容了

增加DCache的配置开关,默认是历史版本,是否可行?

还有个问题,DCache落地对应的mysql,分库分表,只有1,和10的选择。是在建立的时候指定的,后面不能修改?如果随着数据量增大,有不同的分库分表需求怎么办?还是不用太关注这个问题i?

是不能修改的, 所以使用的时候就提前考虑好未来数据的规模.
通常提前考虑好了, 一般就不用太关注这个问题, 如果确实有需要, 就只能手工操作了

那规模会很大,也只能指定分库分表为10,没有找到可以设定为其他的值,是不是这个10这个数量一般也够用,不用考虑其他值?

一般是10库, 10表, 相当于总共100表, 通常是足够了

DCache内的IDC有什么用? 获取数据的接口可以指定idc,设置的数据没有。获取接口中的idc设置不存在的对取数据没有影响

这个一般不要用, 这个用来做异地容灾的
