    This document describes the product specifications, billable items, billing modes, and instance prices of CKafka.

    Product Specifications

    CKafka instances are divided into Standard Edition and Pro Edition according to their specifications. The comparison of the two editions are as follows:

    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 Unavailable. You need to submit a ticket for assistance when the disk is full
    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
    Note:

    The automatic disk cleanup feature is enabled for the Pro Edition by default. When the instance disk is full, the oldest data will be automatically cleared to ensure that the instance is available.

    Billable Items

    The billable items are as follows:

    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.
  • Billing Modes

    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.
  • Note:

    In the pay-as-you-go billing mode, you can select configuration items such as traffic specification and disk capacity as needed, which are billed by the hour (a usage duration that is shorter than one hour will be calculated as one hour). Bills are generated once a month. After you purchase a pay-as-you-go instance, the system will allocate corresponding instance resources. Therefore, in this billing mode, the instance is billed by the instance price multiplied by the service time, regardless of whether the instance is used after purchase.

    Currently, capacity reduction in advance is not supported. You can submit a ticket to apply for capacity reduction. The backend will perform the capacity reduction operation for you before your next billing cycle starts. After, fees will be charged based on the reduced specifications.

    Monthly Subscription

    Pro Edition pricing

    CKafka Pro Edition provides more flexible specification selection modes and more stable upgrade capabilities. You can purchase and scale instances according to your specific business needs.

    Basic package

    After you select the peak bandwidth value for an instance, it will be automatically matched with a corresponding basic package. The basic package in each tier includes a certain number of partitions, and topics are not billed separately. The number of available topics in the package is equal to the number of partitions/the number of replicas.

    The tiers of peak bandwidth (x) are as follows:

    Peak Bandwidth Tier (MB/s) Number of Partitions in the Package
    40 ≤ x < 120 2,000
    120 ≤ x < 320 2,000
    320 ≤ x < 920 2,000
    920 ≤ x < 1,200 2,800
    x = 1,200 3,200
    x = 1,600 8,000
    x = 2,000 10,000
    x = 2,400 12,000
    x = 2,800 14,000
    x = 3,200 16,000
    Note:

    • The fees for the partitions in a package are already included in the package fees, so they will not incur additional fees.
    • If you need CKafka instances with higher specifications, please contact your Tencent Cloud rep or submit a ticket for assistance.

    The price of the basic peak bandwidth package varies by tier, as detailed below:

    Tier Peak Bandwidth Range (MB/s) Price (Monthly Subscription)
    Basic I 40–100 Starting at 360 USD/month and 53 USD/month for each extra 20 MB/s
    Basic II 120–300 Starting at 630 USD/month and 51 USD/month for each extra 20 MB/s
    Basic III 320–600 Starting at 1,200 USD/month and 49 USD/month for each extra 20 MB/s
    Basic IV 620–900 Starting at 2,340 USD/month and 43 USD/month for each extra 20 MB/s
    Basic V 920–1,200 Starting at 3,090 USD/month and 34 USD/month for each extra 20 MB/s
    Premium 1,600–10,000 Starting at 4,150 USD/month and 856 USD/month for each extra 400 MB/s

    For example, a 180 MB/s instance falls into the Basic II tier with 60 MB/s added to 120 MB/s, so the price of the package is 630 + 51 * (60 / 20) = 783 (USD/month)

    Partition package pricing

    After you select the peak bandwidth value, if the number of partitions in the corresponding basic package cannot meet your needs, you can purchase additional partition packages separately. The number of partitions can be increased in increments of 100, as priced below:
