- To ensure stability, the maximum size of a single message is 50 MB. Do not send a message larger than 50 MB.
- In the preceding tables, TPS (of production and consumption) is represented by the number of messages (2 KB each) processed per second. In the tests, persistence and queue mirroring were not enabled. Messages were retrieved immediately after creation and were not accumulated in the queues. The data is for reference only and may differ from that in your production environment.
- Performance is related to the queue quantity, message accumulation, number of connections, number of channels, number of consumers, queue mirroring, priority queue, message persistence, and the exchange type. Select instance specifications based on the pressure test result of the service model.
- A maximum of 2047 channels can be opened on a connection.
- Single-node instances can be used for testing. Do not use them for message production. Single-node flavors are not yet available.
Mapping Between Old and New Flavors
Old and new RabbitMQ instance flavors are compared as follows.

Instances with new flavors have the following features:
- New flavors provide better performance at the same price.
- Old flavors use non-exclusive resources. If the load is heavy, resources conflicts will occur. By contrast, new flavors use exclusive resources so they provide better performance and stability.
- New flavors support scale-out and scale-up to satisfy service changes.
- Larger flavors up to rabbitmq.32u64g.cluster are available now.
Storage Space Selection
In cluster mode, RabbitMQ persists messages to disk. When creating a RabbitMQ instance, select a proper storage space size based on the estimated message size and the number of replicas in a mirrored queue, which can be maximally equal to the number of brokers in the cluster.
For example, if the estimated message size is 100 GB, the disk capacity must be at least: 100 GB x Number of mirrored replicas + 100 GB (reserved).
For single-node instances, select a storage space size based on the estimated message size and the reserved disk space.
You can change the number of brokers in a cluster, but cannot change the specifications of a single-node instance.
