Major API Changes

Defaulting to tracking processors

When an Event Store (or Event Bus implementing StreamableMessageSource) is configured, Axon will default to using tracking processors. This may be overridden using the EventProcessingConfigurer.usingSubscribingProcessors() method.

In Axon 4, the Event Bus itself no longer implements StreamableMessageSource (as was the case in Axon 3), meaning that using the SimpleEventBus will also imply subscribing processors as the default.

Serialization

Instead of throwing an UnknownSerializedTypeException, serializers now return an UnknownSerializedType object, which provides access to the raw data in any supported intermediate representation, such as JsonNode or Dom4J Document.

New Module Structure

We noticed that axon-core was encompassing to big a portion of the whole framework. Thus, we have split it into a couple of reasonable components. It's been split into axon-messaging, axon-modelling, axon-eventsourcing, axon-disruptor and axon-configuration.

The Spring Cloud, AMQP, Kafka, Mongo and JGroups related modules are now published under another Maven Group ID, to emphasise their status as an extension to the framework, rather than a core module. This also means their release schedule may differ slightly from that of the core framework.

The new Group ID's are:

Module	New Group ID
Spring	org.axonframework.extensions.springcloud
AMQP	org.axonframework.extensions.amqp
Kafka	org.axonframework.extensions.kafka
JGroups	org.axonframework.extensions.jgroups
Mongo	org.axonframework.extensions.mongo

Other changes

• TrackingToken removed from AnnotatedSaga and SagaStore implementations
• EventProcessingConfiguration represents an interface for accessing event processing components
• SagaConfiguration is a configuration component carrier only - does not start any processors
• The org.axonframework.kafka.eventhandling.consumer.AsyncFetcher it's Builder solution has been made equal to the other Builder implementations introduced. This entails the following changes:

• The AsyncFetcher constructor has been made protected for overriding
• The AsyncFetcher#builder(Map<String, Object>) function is removed in favor of AsyncFetcher.Builder#consumerFactory(Map<String, Object>)
• The AsyncFetcher#builder(ConsumerFactory<K, V>) function is removed in favor of AsyncFetcher.Builder#consumerFactory(ConsumerFactory<K, V>)

• AsyncFetcher.Builder#withPollTimeout(long, TimeUnit) has been renamed to AsyncFetcher.Builder#pollTimeout(long, TimeUnit)

• The org.axonframework.kafka.eventhandling.producer.DefaultProducerFactory it's Builder solution has been made equal to the other Builder implementations introduced. This entails the following changes:

• The DefaultProducerFactory constructor has been made protected for overriding
• The DefaultProducerFactory#builder(Map<String, Object>) function is removed in favor of DefaultProducerFactory.Builder#configuration(Map<String, Object>)
• A DefaultProducerFactory#builder() is added to instantiate the DefaultProducerFactory.Builder
• DefaultProducerFactory.Builder#withCloseTimeout(int, TimeUnit) has been renamed to DefaultProducerFactory.Builder#closeTimeout(int, TimeUnit)
• DefaultProducerFactory.Builder#withProducerCacheSize(int) has been renamed to DefaultProducerFactory.Builder#producerCacheSize(int)
• DefaultProducerFactory.Builder#withConfirmationMode(ConfirmationMode) has been renamed to DefaultProducerFactory.Builder#confirmationMode(ConfirmationMode)
• DefaultProducerFactory.Builder#withTransactionalIdPrefix(String) has been renamed to DefaultProducerFactory.Builder#transactionalIdPrefix(String)

• Renamed CommitEntryConfiguration.Builder functions to align with new builder approach:

• withFirstTimestampProperty(String) -> firstTimestampProperty(String)
• withLastTimestampProperty(String) -> lastTimestampProperty(String)
• withFirstSequenceNumberProperty(String) -> firstSequenceNumberProperty(String)
• withLastSequenceNumberProperty(String) -> lastSequenceNumberProperty(String)
• withEventsProperty(String) -> eventsProperty(String)

• Renamed EventEntryConfiguration.Builder functions to align with new builder approach:

• withTimestampProperty(String) -> timestampProperty(String)
• withEventIdentifierProperty(String) -> eventIdentifierProperty(String)
• withAggregateIdentifierProperty(String) -> aggregateIdentifierProperty(String)
• withSequenceNumberProperty(String) -> sequenceNumberProperty(String)
• withTypeProperty(String) -> typeProperty(String)
• withPayloadTypeProperty(String) -> payloadTypeProperty(String)
• withPayloadRevisionProperty(String) -> payloadRevisionProperty(String)
• withPayloadProperty(String) -> payloadProperty(String)
• withMetaDataProperty(String) -> metaDataProperty(String)

• Renamed EventSchema.Builder functions to align with the new builder approach:

• withEventTable(String) -> eventTable(String)
• withSnapshotTable(String) -> snapshotTable(String)
• withGlobalIndexColumn(String) -> globalIndexColumn(String)
• withTimestampColumn(String) -> timestampColumn(String)
• withEventIdentifierColumn(String) -> eventIdentifierColumn(String)
• withAggregateIdentifierColumn(String) -> aggregateIdentifierColumn(String)
• withSequenceNumberColumn(String) -> sequenceNumberColumn(String)
• withTypeColumn(String) -> typeColumn(String)
• withPayloadTypeColumn(String) -> payloadTypeColumn(String)
• withPayloadRevisionColumn(String) -> payloadRevisionColumn(String)
• withPayloadColumn(String) -> payloadColumn(String)
• withMetaDataColumn(String) -> metaDataColumn(String)

• Renamed AbstractEventStorageEngine#getSerializer() to AbstractEventStorageEngine#getSnapshotSerializer()
• Renamed SimpleEventHandlerInvoker#eventListeners() to SimpleEventHandlerInvoker#eventHandlers()

Command Message Routing

Introduced the @RoutingKey annotation, which is an annotation of the @TargetAggregateIdentifier. Additionally, adjusted the AnnotationRoutingStrategy to check for a (meta-)annotated RoutingKey field i.o. @TargetAggregateIdentifier.

Domain Event Sequences

The contract to be able to provide the last known sequence for a given aggregate identifier has been moved from the EventStore to a (new) interface, the DomainEventSequenceAware.
