Latest Patents

Junhui He holds a patent titled "Idempotent event handling." This patent introduces a partition-based method to implement idempotence in an event-driven architecture. The method aims to reduce the pressure of database reading and writing, thereby enhancing the overall performance of event handling. To improve parallelism, He establishes a consumer cluster, which consists of multiple consumers sharing the responsibility of processing events. Events are distributed among different partitions within the cluster, with each partition containing a unique consumer worker equipped with its own cache. An event dispatch module is utilized to balance the load by dispatching events among the consumer workers. This is achieved by generating a partition identification for an event based on a hash of the context identification of the session established between the user and the application when the event was generated, followed by a modulo operation based on the number of consumer workers in the cluster.
