> In asynchronous execution model (FLIP-425) for state, the key is managed by the framework and automatically assigned before {{processElement}} or callback running. However in some cases, there should be an internal interface that allows to switch key and start a new process with this key. It is useful when implementing something like mini-batch, which triggers a batch of real logic for gathered elements at one time instead of the {{processElement}} for each element.
> Additionally, the processing invoked by this interface should have a higher priority than the normal input, as the semantics of this processing method is to continue processing the previously half-processed data.
