An event processing system comprising a processor and a non-transitory computer readable medium coupled to the processor. The non-transitory computer readable medium stores computer-readable code executable to provide a domain-agnostic service for analyzing data and process heterogeneous events conforming to a plurality of schemas using the service. The domain-agnostic service comprises an adaptive data model and an adaptive processing model. The adaptive data model supports runtime event type discovery and event schema management that reacts to new schemas discovered at runtime. The adaptive processing model supports configurable partitioning of events by event type and time and is reactive to create new aggregations and analyses based on the propagation of new partitions.
