org.axonframework.saga.annotation.AsyncAnnotatedSagaManager

A SagaManager implementation that processes Sagas asynchronously. Incoming events are placed on a queue and processed by a given number of processors. Modified saga state is persisted in batches to the repository, to minimize communication overhead with back-ends.

This SagaManager implementation guarantees a "happens before" type processing for each Saga. That means that the behavior of asynchronously processed events is exactly identical as the behavior if the events were processed completely sequentially. @author Allard Buijze @since 2.0
