12.6. Event Processing Modes

Rules engines process facts and rules to provide applications with results. Regular facts (facts with no temporal constraints) are processed independent of time and in no particular order. JBoss BRMS processes facts of this type in cloud mode. Events (facts which have strong temporal constraints) must be processed in real-time or near real-time. JBoss BRMS processes these events in stream mode. Stream mode deals with synchronization and makes it possible for JBoss BRMS to process events.
