14. Type of Queues
 Queue: The queue is a storage area where messages are
stored for processing.
 Exchange: The exchange is used for broadcasting a
messages, like one message to multiple consumers. If any
message is send to the exchange, it will be forwarded to all
the the queues binded with it.
 FIFO (first in, first out): FIFO is a normal queue where
messages are stored.The FIFO queue is used when
message need to be consumed in order.

15. Type of Queues
 Queue: The queue is a storage area where messages are
stored for processing.
 Exchange: The exchange is used for broadcasting a
messages, like one message to multiple consumers. If any
message is send to the exchange, it will be forwarded to all
the the queues binded with it. we cannot bind FIFO queue
to exchange.
 FIFO (first in, first out): FIFO is a normal queue where
messages are stored.The FIFO queue is used when
message need to be consumed in order.

16.  The dead-letter queue or (undelivered-message queue) is the queue to which messages are
sent if they cannot be routed to their correct destination.
 Few things to remember before creating a DLQ.
The DLQ and parent queue both need to be:
 Same type of queue (standard or FIFO)
 Created in the same geographical region
 Created in the same environment and owned by the same Anypoint Platform account
Dead Letter Queue (DLQ)

DLQ Flowchart

18. Types of Connectors
 Subscriber to subscribe to the queue and listen for the receiving
message. (Event source)
 Publish to publish the message to the Queue.
 Consumer to consume a message from the queue.
 Ack to send an acknowledgement to the queue about the
successful consumption of the message and delete the message
from in-flight status.
 Nack to send negative acknowledgement to the queue stating the
consumed message is not processed successfully; changes the
status of the message from in-flight to in-queue to be consumed
again by an available consumer.
18

19. Message Acknowledgment
 Automatic: By default, the Subscriber source uses the AUTO acknowledgment mode.
With this mode, the messages that the Subscriber source retrieves are acknowledged
automatically after message flow processing succeeds.
 Immediate: When you use the IMMEDIATE acknowledgment mode, the consumed
message is acknowledged right before being dispatched to the Mule flow.
 Manual: When you use the MANUAL acknowledgment mode, the application logic
decides when to perform the acknowledgment of the message, using
the ACK or NACK sources. To perform the manual acknowledgment, you need the value
of ack token provided as part of the resulting message attributes.
19

20. Configuration
Main elements required:
 URL: Destination url.
 Client API ID: Id from
Client Apps.
 Client Secret: Secret
from client Apps.
20

21. Circuit Breaker
21
 The Subscriber source provides circuit breaking capability, which enables you to
control how the connector handles errors that occur while processing a consumed
message.
 For example, when connecting to an external service, you can use the circuit breaker to
handle any downtime of that service. The circuit breaker allows the system to stop making
requests and allows the external service to recover under a reduced load.
The circuit breaker has three states:
 Closed: Normal retrieval and processing of message based on the subscriber strategy.
 Half Open: Retrieve a single message and attempt to process it.
 Open: Scheduled message fetch are skipped and no more messages are processed.

22. Error Types
 ANYPOINT-MQ:ACKING
 ANYPOINT-MQ:TIMEOUT
 ANYPOINT-MQ:NACKING
 ANYPOINT-MQ:PUBLISHING
 ANYPOINT-MQ:CONSUMING
 ANYPOINT-MQ:CONNECTIVITY
 ANYPOINT-MQ:ILLEGAL_BODY
 ANYPOINT-MQ:RETRY_EXHAUSTED
 ANYPOINT-MQ:DESTINATION_NOT_FOUND

23. Anypoint MQ REST APIs
Anypoint MQ APIs enable you to use REST to send and receive messages, administer
queues and message exchanges, and analyse results.
Anypoint MQ provides these APIs:
 Anypoint MQ Admin API: This API allows users to manage their destinations.
 Anypoint MQ Broker API: This API allows clients to send & receive messages from
queues & exchanges.
 Anypoint MQ Stats API: This API allows users to view statistics for destinations.

25. Limitations of Anypoint MQ
 Anypoint MQ cannot be deployed on-premises.
Note: We have REST APIs to overcome this limitation.
 Max size of payload is limited to 10 MB, cannot process payloads larger than 10 MB.
