> We have introduced the `EpochManager` to handle the watermark during async
> state processing. The inputs are divided into several epochs where a action
> is attached and triggered after all the inputs finished their async
> processing. However, the action itself may trigger more async procedures
> which blocks some synchronous action. Thus it is better to introduce two
> types of action, one is for triggered right after all the inputs finished,
> while another is for being triggered after all the async processing including
> the ones from the action finished.
