我觉得，addMarker放在effect里面。

没有觉得reduce有间隔呀？有稍微详细点儿的代码么？

there is a `ShouldUpdate shouldUpdate,` parameter of page/component which let you to define your view rebuild timing.

@henry-hz I think they are different things. `shouldUpdate` is for **how** to update(rebuild) view, and stream subscription is like **when** to update state.

reducer 没有被执行。所以不会rebuid。

Same issue here.
