Configuration Item | Parameter | Parameter Description |
Basic Configuration | Product Form | Serverful: The classic form of CKafka. Users can purchase clusters of corresponding specifications based on requirements. As business volume changes, certain attention needs to be paid to the CKafka cluster. Serverless: A brand-new form of CKafka. The goal is to completely release the user's effort and focus more on business logic. Currently in public beta. |
| Billing Mode | Pro edition instances support two modes: Monthly Subscription and pay-as-you-go. Advanced Edition Instances support Monthly Subscription mode. Monthly Subscription: Payment is required in advance to use resources. It is mainly suitable for scenarios where the business is relatively stable and used for a long time. Pay-as-you-go: Use resources first and then pay. It is mainly suitable for short-term situations such as testing or when the traffic peak is uncertain. |
| Cluster Type | The professional edition is primarily aimed at production environment customers on a large scale. The advanced edition is mainly for test environment customers in small-scale scenarios. For specific differences, refer to product spec. Here you can select advanced edition. |
| Region | Select a region with resources close to those of the client deployment. For regions currently supported by CKafka, see Regions and Availability Zones. |
Cluster Configuration | Name | If not filled in, the default is unnamed. When purchasing multiple instances, you can create instance suffix numbers in automatic ascending order and specify a pattern string feature. For specific operations, refer to Batch sequential naming or naming with specified pattern strings. |
| Kafka version | Choose an appropriate Kafka version according to your business needs. See Version selection suggestions for CKafka. |
| Peak Bandwidth | Estimate the resource amount of peak bandwidth according to the rule of peak bandwidth of business traffic × number of replicas. CKafka will accumulate the bandwidth consumption of all replicas to calculate the actual peak bandwidth. |
| Disk | The currently supported disk types are SSD Cloud Block Storage and high-performance cloud block storage. For the differences in cloud disk types, please refer to Cloud Disk Type. |
| Partition specification | The Partition limit for a CKafka instance is the cumulative total of number of partitions * number of replicas. The number of partitions included in the package (i.e., the minimum value) is free of charge. Additional partitions are billed in units of 100. Downgrading is not supported at this time. |
| Message retention | Ranges from 24 to 2160 hours. The default message retention time is 72 hours. After exceeding the set retention duration, messages will be deleted to preserve sufficient disk space. CKafka supports the automatic adjustment of disk utilization. When the disk utilization reaches the threshold, you can choose to set the Dynamic Message Retention Policy to reduce message retention time or set the Automatic Disk Capacity Expansion to adjust disk space. For details, see Disk Water Level Processing. |
| Cross-AZ Deployment | The professional edition supports deployment in a maximum of 4 different availability zones, and the advanced edition supports deployment in a maximum of 2 different availability zones. For how cross-availability zone deployment works, please refer to Cross-AZ Deployment. |
Network Configuration | VPC Network | If users need to connect to other private networks, please refer to Add Routing Policy Modify the routing access rules. Select the network created in advance here. |
Other configuration | Tag | Tags are used to manage resources by category from different dimensions. For method of use, see Tag Management. Leave blank here. |
| Automatic Renewal | After checking, when the account balance is sufficient, instances and public network bandwidth will be auto-renewed monthly after expiration. |
