When you select specifications for a new cluster, base your decision on the current business load (including the message throughput, the number of connections, and the number of queues) as well as future scalability needs. Consider CPU, memory, disk, and node resources comprehensively. Use monitoring data from the existing cluster as a reference to ensure the new cluster reserves a 20% to 30% performance buffer, and verify version compatibility. TDMQ for RabbitMQ supports online adjustment of cluster specifications, allowing you to deploy based on baseline requirements during the initial migration phase, and then scale in or out based on actual business pressure.
