Function Overview

Before using DMS for RabbitMQ, you must buy a RabbitMQ instance. RabbitMQ instances are physically isolated and exclusively occupied by each tenant.

Connect an open-source RabbitMQ client to a RabbitMQ instance before using the client to create and retrieve messages.
DMS for RabbitMQ provides sample code with SSL enabled and disabled. You can use the sample code to test whether your client and instance can be connected.

After creating a RabbitMQ instance, you can increase or decrease its specifications.

To access a RabbitMQ instance over a public network, enable public access and configure EIPs for the instance.

After creating a RabbitMQ instance, you can enable the following plug-ins: rabbitmq_amqp1_0, rabbitmq_delayed_message_exchange, rabbitmq_federation, rabbitmq_sharding, rabbitmq_shovel, rabbitmq_tracing, rabbitmq_mqtt, rabbitmq_web_mqtt, rabbitmq_stomp, rabbitmq_web_stomp, and rabbitmq_consistent_hash_exchange plug-ins. The plug-ins are disabled by default when an instance is created.
When plug-ins are enabled, the instance will not be restarted. However, enabling plug-ins rabbitmq_mqtt, rabbitmq_web_mqtt, rabbitmq_stomp, and rabbitmq_web_stomp will restart Keepalived and disconnect the instance. After the instance is disconnected, it may be automatically reconnected, depending on the service logic.

Open-source RabbitMQ provides many advanced features, such as lazy queues, quorum queues, dead lettering, and TTL. You can define these features by calling functions on your client or by using the RabbitMQ management UI.
Single active consumer and quorum queues are available only in RabbitMQ 3.8.35 and later versions, and not in 3.7.17.

Tags facilitate RabbitMQ instance identification and management.
You can add tags to a RabbitMQ instance when creating the instance or add tags on the details page of the instance later. Up to 20 tags can be added to an instance.

Cloud Eye monitors RabbitMQ instance metrics in real time. You can view these metrics on the console.

RabbitMQ operations are recorded by Cloud Trace Service (CTS), which is a log audit service provided by Huawei Cloud. CTS collects, stores, and queries records of operations on RabbitMQ instances, facilitating security analysis, compliance audit, resource tracking, and fault locating.

DMS for RabbitMQ provides REST APIs that support HTTP/HTTPS methods. You can call APIs to create, delete, and modify instances.
