Embodiment Construction
[0025] Those skilled in the art understand that, as mentioned in the background art, when the status of a workflow task is abnormal, if the recovery method of pure event flow is adopted, the entire event flow needs to be traced back. If the recovery method of the traditional state machine is adopted, it may be impossible to recover. To the event of the ring graph leads to re-tracing the entire event flow, and event recovery efficiency is low.
[0026] In the embodiment of the present invention, an event stream is created in the process of workflow task status transfer. The event stream may include multiple events, and the events are obtained by dividing and defining the transfer links of the workflow task status in advance; the event stream also It may include at least one snapshot, and each snapshot may include a collection of at least part of the information of the event stream at a single point in time. It can be seen that the snapshot can record various events and event inform...
