> Currently, Kylin supports mail service to know the change around the cube.
> However, there are some issues about the design, e.g.
> * AbstractExecutable contains an implementation of the mechanism of a
> notification listener, but only support mail service, it does not belong
> there;
> * The current implementation is hard to scale to other notification e.g.
> Ding Talk(which is a popular production supports by Alibaba)
> I propose to refactor the current implementation to extract the notification
> logic and redesign a new common notification/listener
