An asynchronous state change notification method, system and device

Abstract

The invention discloses an asynchronous state change notification method, system and device. When a target state in the system changes, the instance index corresponding to the changed target state is recorded; it is judged whether there is an unprocessed asynchronous notification event currently. ; if not, send the first asynchronous notification event to the event processing module, so that the event processing module performs notification callback based on the instance index of this record, and marks the first asynchronous notification event as processed after the notification callback is completed ; if so, wait for the unprocessed asynchronous notification event to complete processing, and do not trigger a new asynchronous notification event. It can be seen that during the period from when an asynchronous notification event is triggered due to state jitter to the completion of processing of the asynchronous notification event, only one asynchronous notification event is generated by the state jitter, thereby avoiding the waste of resources and low system operation efficiency caused by frequent notification callbacks. .

Description

technical field [0001] The present invention relates to the field of state change notification, in particular to an asynchronous state change notification method, system and device. Background technique [0002] In a software system, when a certain data state changes, specific actions need to be taken to deal with this state change. Usually, a subscription for state change is added, that is, when the state changes, the notification callback function is called immediately to notify the subscription. By. However, in some scenarios, state jitter may occur, that is, a state changes multiple times in a short period of time, and subscribers are notified each time it changes, especially when a state corresponds to multiple instances, This state jitter will be magnified exponentially, resulting in frequent notification callbacks. Frequent notification callbacks not only waste resources, but also seriously affect the operating efficiency of the system. [0003] Therefore, how to pr...
