public interface AsyncRequestContainer<REQUEST extends AsyncRequest<?>>
```
A container which is used to hold AsyncRequests. The role of AsyncRequestContainer is to serve as an intermediary carrier for data transmission between the runtime layer and the state layer. It stores the stateRequest from the runtime layer, which is then processed by the state layer.
Notice that the AsyncRequestContainer may not be thread-safe.
