Guarantees for decentralized event correlation
Gregory Aaron Wilkin, Patrick Th. Eugster · 2011
Many distributed applications rely on forms of event correlation, which result in atomic delivery of multiple events aggregated by following process-specific criteria. Generally, more than one process is aggregating events, implying that events are multicast. While delivery guarantees for multicast scenarios with single event/message delivery are well understood, existing systems and models for aggregated deliveries either consider only unicast, centralized setups, or focus on efficiency thus providing only best-effort guarantees.
