Event scheduling system

The invention discloses an event scheduling system, which comprises a file transmission assembly, an event management assembly and a scheduling server, wherein the file transmission assembly sends a file arrival event to the event management assembly through a post-trigger way when a monitoring result shows that an external system introduces a file in; the event management assembly inquires whether a job flow corresponding to the file arrival event finishes instantiation or not, and determines the instantiation of the job flow or the transmission of the file arrival event according to a query result; and the scheduling server schedules and executes the instantiated job flow corresponding to the file arrival event when the file arrival event is received. The external system utilizes the file transmission assembly to input the file, the file transmission assembly sends the file arrival event to the event management assembly through the post-trigger way so as to guide the event management assembly to carry out t
