Interface Summary
Interface	Description
DurableQueueConsumer	`DurableQueues` consumer
DurableQueueConsumerNotifications	Notification interface that `DurableQueueConsumer` can implement if they want to be notified about messages being added to the queue they're consuming from This is required for `DurableQueueConsumer`'s that use a `QueuePollingOptimizer`
DurableQueues	The `DurableQueues` concept supports intra-service point-to-point messaging using durable Queues that guarantee At-Least-Once delivery of messages. The only requirement is that message producers and message consumers can access the same underlying durable Queue storage.
DurableQueuesInterceptor
QueuedMessage	Represents a `Message` that has been queued using `QueueMessage`/`QueueMessages`/`QueueMessageAsDeadLetterMessage`
QueuedMessageHandler
QueuePollingOptimizer	Optimizer designed to work together with the `DefaultDurableQueueConsumer` The optimizer is responsible for optimizing the frequency by which the `DefaultDurableQueueConsumer` is polling the underlying database for new messages related to a given `QueueName`. If a given Queue doesn't experience a high influx of message, or a lot of message's have (`QueuedMessage.getNextDeliveryTimestamp()`) that is further into the future, then it doesn't make sense to poll the database too often. The `QueuePollingOptimizer.SimpleQueuePollingOptimizer` supports extending the polling sleep time (i.e.

Class Summary
Class	Description
DefaultDurableQueueConsumer<DURABLE_QUEUES extends DurableQueues,UOW extends UnitOfWork,UOW_FACTORY extends UnitOfWorkFactory<UOW>>	The default `DurableQueueConsumer` which provides basic implementation (including retrying messages in case of failure, polling interval optimization, etc.)
DefaultQueuedMessage	Represents a message queued onto a Durable Queue
Message	Encapsulates a Message, which is a `Pair` of Payload and its `MessageMetaData`
MessageMetaData	Encapsulated Metadata (like headers, correlation id, tracing id's, etc.) associated with a `Message`
NextQueuedMessage
OrderedMessage	Represents a message that will be delivered in order. This of course requires that message are queued in order and that the consumer is single threaded. All messages sharing the same `OrderedMessage.key`, will be delivered according to their `OrderedMessage.order` An example of a message key is the id of the entity the message relates to
PatternMatchingQueuedMessageHandler	Pattern matching `QueuedMessageHandler` for use with `DurableQueues`'s The `PatternMatchingQueuedMessageHandler` will automatically call methods annotated with the @MessageHandler annotation and where the 1st argument matches the actual Message payload type (contained in the `Message.getPayload()` provided to the `QueuedMessageHandler.handle(QueuedMessage)` method)
QueueEntryId	The unique entry for a message in a queue.
QueueName	The name of a Durable Queue
QueuePollingOptimizer.SimpleQueuePollingOptimizer	The `QueuePollingOptimizer.SimpleQueuePollingOptimizer` supports extending the polling sleep time (i.e.

Enum Summary
Enum	Description
DurableQueues.QueueingSortOrder	The sorting order for the `QueuedMessage.getId()`
QueuedMessage.DeliveryMode
TransactionalMode	The transactional behaviour mode of a `DurableQueues`
