Anypoint MQ Channel Binding v0.0.1 ​

The Anypoint MQ channel binding object specifies the configuration for an Anypoint MQ destination, which can be an exchange, a queue, or a FIFO queue.

Overview ​

This binding allows you to describe the Anypoint MQ destination that corresponds to an AsyncAPI channel. You can specify the destination's name and its type, which determines the messaging model (e.g., publish-subscribe vs. point-to-point).

Channel Properties ​

PropertyTypeRequiredDescription
destinationstringNoThe name of the destination (queue or exchange). If not provided, the channel name is used as the destination name.
destinationTypestringNoThe type of the destination. Can be exchange, queue, or fifo-queue. Defaults to queue.
bindingVersionstringNoThe version of the Anypoint MQ channel binding. For this version, the value is 0.0.1.

Examples ​

Point-to-Point Queue ​

This example defines a standard queue for point-to-point messaging.

yaml
channels:
  user-processing-queue:
    bindings:
      anypointmq:
        destination: 'user-processing'
        destinationType: 'queue'
        bindingVersion: '0.0.1'

Publish-Subscribe Exchange ​

This example defines an exchange for broadcasting messages to multiple subscribers.

yaml
channels:
  domain-events:
    bindings:
      anypointmq:
        destination: 'domain-events-exchange'
        destinationType: 'exchange'
        bindingVersion: '0.0.1'

FIFO Queue for Ordered Processing ​

This example defines a FIFO queue to ensure that messages are processed in the exact order they are received.

yaml
channels:
  transaction-log:
    bindings:
      anypointmq:
        destination: 'transaction-log-queue'
        destinationType: 'fifo-queue'
        bindingVersion: '0.0.1'

Use Cases ​

Decoupling Services with Queues ​

Use a queue destination to send tasks to a pool of worker services. Each task will be processed by only one worker, allowing you to decouple the sender from the receivers.

Broadcasting Events with Exchanges ​

Use an exchange to publish events to multiple interested services. For example, a "user created" event could be sent to an email service, an analytics service, and a welcome campaign service simultaneously.

Maintaining Order with FIFO Queues ​

When the sequence of events is critical, such as in financial transactions or inventory updates, use a fifo-queue to guarantee that messages are processed in the order they were sent.
