<p>A hybrid event processing network (EPN) having at least one event processing agent (EPA) consists of a first set of EPAs defined declaratively and a second set of EPAs defined dynamically at runtime via an interface. Deploying the hybrid EPN includes loading the hybrid EPN, constructing an EPN structure, and creating indexes of nodes of the EPN structure. Deploying the hybrid EPN further includes representing an event in a hybrid EPN, and, in response to the event occurrence at an event source, receiving a notification from the hybrid EPN based on the event, and publishing the notification in an event channel. Embodiments of the invention includes propagating the event received within the hybrid EPN, determining a subsequent EPA associated with the event within the hybrid EPN, and propagating the event to the subsequent EPA in the hybrid EPN until the last element of the hybrid EPN is reached.</p> |
