Last updated:2026-01-20 16:39:56
This document describes the billing modes and pricing details for the private network bandwidth of TDMQ for CKafka (CKafka).
Item | Applicable Scope | Description | Billing Mode |
Peak bandwidth (required) | Full series | This refers to the private network bandwidth. To estimate the peak bandwidth resource, calculate it based on the rule of Peak bandwidth of business traffic x Number of replicas. CKafka accumulates the bandwidth consumption of all replicas to calculate the actual peak bandwidth. For example, if the business requires 40 MB bandwidth and 3 replicas, you need to purchase a peak bandwidth of 120 MB/s. | Yearly/Monthly subscription and postpaid by hour |
Elastic bandwidth (optional) | Pro Edition | After this option is enabled, if the business traffic exceeds the purchased cluster bandwidth specification, the excess part will be billed based on actual usage. If the traffic does not exceed the specification, no additional fees will be incurred. This is suitable for scenarios where the business occasionally experiences burst traffic. | Pay-as-you-go |
