One embodiment provides event handling in a cloud based multi-tenant identity management system. Embodiments receive a plurality of individual events and a request to create a group from the individual events. Embodiments publish the group as a composite event and persist the composite event in a composite queue. Embodiments then dispatch the composite event to a composite handler, parse the composite event and persist the individual events in respective event queues.

The embodiment of the invention discloses a complex event processing method and device. The method comprises the steps of: after receiving base events, determining an event mode to which the base events belong according to the event information of the base events, wherein the base events carry event labels; inputting the base events into a state machine instance corresponding to the event labels, wherein the state machine instance is created by a state machine defined according to the event mode to which the base events belong, and the base events belonging to the same state machine instance have the same event label; and outputting a complex event according to a state transition result according to the state machine instance. According to the embodiment of the invention, the complex event is output by means of the state transition result of the state machine instance, so that the consumed storage space of a system for storing a large number of base events is reduced; in addition, because the definition of the state machine specific to a certain event mode can be transformed according to actual application demands, the flexibility of the system in complex event processing is enhanced.

The invention discloses an event pattern matching method facing a real-time perceptual environment and a system thereof. According to the method, through considering influences of a system response timing constraint requirement and event pattern complexity on event pattern matching real-time performance, after utilizing a system response timing constraint acquisition module to obtain a timing constraint requirement of current service rule system response and utilizing an event pattern complexity analysis module to obtain quantized complexity of current event pattern, an event pattern priority assignment module gives priority of the current event model, when a composite event matching model shows that a single state node has a plurality of direct sub-state nodes, an event pattern matching model optimization and scheduling module allows direct sub-state nodes belonging to an event pattern with high priority to execute matching according to the priority of the current event model so as to satisfy a timing requirement of real-time perceptual environment system response. The invention also discloses an event pattern matching system facing the real-time perceptual environment corresponding to the above method.

When detecting the change of the compound event conditional expression, the rule comparison unit compares the compound event conditional expression before and after the change. The changed portion identifying unit identifies the changed portion based on the comparison result, and the parallel operation unit operates the compound event conditional expression before and after change in parallel for the detected compound event conditional expression including the identified changed portion. In this manner, the compound event processing apparatus disclosed herein is capable of dynamically changing the detected compound event condition expressions used in compound event processing.
