RULE DISTRIBUTION DEVICE, EVENT PROCESSING SYSTEM, RULE DISTRIBUTION METHOD, AND RULE DISTRIBUTION PROGRAM

摘要

Provided are a rule distribution device, an event processing system, a rule distribution method, and a rule distribution program that can process a large number of events in real time while reducing the load of the network and the load of the processing server. The rule distribution device includes: a rule reception unit (11) for receiving processing rules that stipulate event processes requested by applications and event conditions used to execute the event processes; a key attribute determination unit (14) for determining key attributes among the attributes included in the event conditions of the processing rules; a rule distribution destination calculation unit (13) for distributing a processing rule to a processing device selected from among the processing devices associated with the key attributes; and a distribution rule generation unit (15) for generating an event distribution rule that distributes an event output from a terminal to a processing device to which a processing rule that processes the event is distributed and for distributing the event distribution rule to an event distribution device installed between the processing device and the terminal.
