Scenarios
When you select specifications for a new instance, base your decision on the current workload (such as peak bandwidth, storage, and the number of partitions) as well as future scalability needs. It is recommended to use monitoring data from the existing instance as a reference to ensure the new instance reserves a 20% to 30% performance buffer and verify version compatibility. TDMQ for CKafka (CKafka) supports online adjustment of instance specifications, allowing you to deploy an instance based on baseline requirements during the initial migration phase, and then scale in or out based on actual business pressure.
