Item | Pro Edition | Standard Edition |
Version | Compatible with open-source versions 0.10, 1.1, and 2.4, which can be freely selected upon purchase | Compatible with open-source versions 0.10 and 1.1. v1.1 is installed by default. Customized versions are not supported |
Instance type | Dedicated instance (each instance has a separate cluster of independent virtual nodes) | Shared physical node resources |
Stability SLA | 99.995% | 99.95% |
Instance specification | There are no fixed models, and the specifications can be customized according to the actual business scenario | There are 8 fixed instance types, including small, standard, and advanced |
Topic/Partition specification | The topic/partition capacity is much larger than that on the Standard Edition under the same bandwidth. Additional partition packages can be purchased within a certain range to increase the upper limit | Each model has a fixed upper limit |
Scalability | Its scalability is high, and the upper limits of bandwidth, topics/partitions, and disks can be increased separately | Its scalability is low, and its disk can be expanded separately |
Performance tuning | The performance can be customized according to the business scenario with fewer parameter restrictions | The numbers of topics and partitions are limited according to the different instance specifications |
Automatic disk cleanup | Available. Expired data is cleared regularly | |
Broker repair and upgrade | Targeted upgrades are available, and the upgrade process is fast and almost imperceptible with high stability | Subject to shared cluster resources, upgrades for problem fixes take a long time |
High availability | Custom multi-AZ deployment in the same region is supported to improve the disaster recovery capabilities | Multi-AZ deployment in the same region is not supported. It relies on backend migration and requires you to submit a ticket to apply, which generally takes 10 business days for processing |
Advanced features | Timed rebalance (you can customize the rebalance execution time during upgrade to avoid business peak hours. For more information, please see Upgrading Instances). Advanced monitoring (this includes network stability analysis and request delay analysis. For more information, please see Querying Advanced Monitoring Information). Dynamic message retention policy adjustments based on disk utilization (for more information, please see Adding Dynamic Message Retention Policies) | None |
Technical support | Parameter optimization consulting services are supported, helping you customize parameter configurations for certain special business scenarios. You can submit a ticket to apply for parameter optimization consulting services | Basic troubleshooting and problem fixing |
Item | Pro Edition | Standard Edition | Description |
Peak bandwidth | ✔ | ✔ | Throughput refers to the outbound and inbound bandwidth peak. For example, a throughput of 40 MB indicates that the outbound and inbound peak bandwidth is 40 MB. The replicas of an instance share the throughput equally. For example, for a throughput of 40 MB and three replicas, you should purchase a bandwidth with a throughput of 120 MB/s. |
Disk capacity | ✔ | ✔ | The disk capacity varies by instance specification. CKafka Standard Edition supports SSD cloud disks. CKafka Pro Edition supports SSD and premium cloud disks. |
Partition | ✔ | - | The number of partitions varies by instance specification, and additional partitions can be purchased separately for the Pro Edition. Topics are free of charge for the Pro Edition, and the maximum number of available topics is equal to the number of partitions/the number of replicas. The number of partitions cannot be reduced. The instance-level partition limit applies to the number of replicas. For example, if an instance has one topic with two replicas and each with four partitions, and two topics with three replicas and each with three partitions, then the total number of partitions in this instance will be (1 * 2 * 4) + (2 * 3 * 3) = 26. |
Mode | Pro Edition | Standard Edition | Description |
Monthly subscription | ✔ | - | The total fees of a purchased Pro Edition instance are (basic package price + partition package price * number of additional partitions / 100 + disk capacity price * disk capacity / 100) * number of months. For detailed prices, please see Pro Edition pricing. |
Pay-as-you-go | ✔ | ✔ | The total fees of a purchased Pro Edition instance are (basic package price + partition package price * number of additional partitions / 100 + disk capacity price * disk capacity / 100) * number of hours. For detailed prices, please see Pro Edition pricing. The total fees of a purchased Standard Edition instance are (basic package price + disk capacity price * disk capacity / 100) * number of hours. For detailed prices, please see Standard Edition pricing. |
