When a large number of messages need to be processed, expanding the RabbitMQ instance is a common solution. Expansion can increase the throughput, storage capacity, and availability of a RabbitMQ cluster. DMS RabbitMQ provides three types of expansion solutions (node, specification, and disk) to better meet user requirements in different scenarios.
l Node expansion: Add nodes to the RabbitMQ cluster to increase the throughput and reliability of the system. Through expansion, you can distribute the loads of sending and consuming messages to more nodes, improving the concurrency processing capacity of the system.
l Specification expansion: Increases the processing power and performance of the system by increasing RabbitMQ resources.
l Disk expansion: Increases the storage capacity of the disk to more messages.
