EVENT PROCESSING WITH ENHANCED THROUGHPUT

The present systems and methods allow for rapid processing of large volumes of events. A producer node in a cluster determines a sharding key for a received event from an event stream. The producer node uses a sharding map to correlate the sharding key for the event with a producer channel, and provides the event to a producer event buffer associated with the producer channel. The producer event buffer transmits the event to a corresponding consumer event buffer associated with a consumer channel on a consumer node. The event processing leverages a paired relationship between producer channels on the producer node and consumer channels on the consumer node, so as to generate enhanced throughput. The event processing also supports dynamic rebalancing of the system in response to adding or removing producer or consumer nodes, or adding or removing producer or consumer channels to or from producer or consumer nodes.
