Aggregators Module Release Notes

Aggregators Module contains different types of aggregators that use a specified configuration to both store and release values. An aggregator scope is a component that collects those values until a specified condition is met, when it then executes a processor’s chain of components, with the list of aggregated elements as the payload.
