Pro Cluster Billing

Last updated: 2024-04-25 15:38:23
    This document describes the billing mode of TDMQ for Pulsar pro cluster.

    Billable Items

    TDMQ for Pulsar pro cluster is monthly subscribed (prepaid) with the following billable items:
    Cluster specifications
    Storage specifications

    Billable Specification

    Cluster specification limits

    Max Messaging TPS: Indicates the upper limit on the messaging (production and consumption) TPS of a TDMQ for Pulsar pro cluster.
    Note:
    The max messaging TPS varies by cluster specification. For more information, see Pro Cluster Specification.
    Peak Bandwidth: If it is set to 45 MB/s, both the outbound and inbound bandwidth of the TDMQ for Pulsar pro cluster can reach up to 45 MB/s, including the traffic of three replicas.
    Other resource limits: Besides TPS and bandwidth, cluster specifications also vary in terms of certain controlled resources and configuration limits. For details, see Pro Cluster Specification‌.

    Exceeded Specification Limits

    Pro Cluster - Fixed Storage

    If your actual usage exceeds the purchased cluster's specification limit, the current platform will not implement throttling measures (expected to be launched in Q3 2024). It is recommended to subscribe to the alarms for the cluster's core metrics, pay attention to metric changes and corresponding performance, promptly upgrade the cluster specification, and ensure stable business operation. We will consider providing elasticity in the future to avoid this issue.

    Pro Cluster - Elastic Storage

    If your actual usage exceeds the purchased cluster's specification limit, based on the sending/receiving ratio that you configured when creating the cluster, the platform will implement throttling . This will affect the normal sending and receiving of messages. It is recommended to subscribe to the cluster's core metric alarms and promptly upgrade the cluster specification to ensure stable business operation.

    Cluster TPS Specification

    1. Messaging TPS refers to the maximum sum of messages sent and subscribed per second.
    2. For advanced feature messages, there are two scenarios:
    For scheduled/delayed messages, transaction messages, and Key-Share subscription, the number of calls when sending messages should be multiplied by a factor of 5 times the rate of normal messages. For example, sending 1,000 delayed messages per second would result in a message send TPS of 1,000 x 5 = 5,000 times/second.
    For tag messages, production is calculated as normal messages, and the filtered message count will be increased in consumption measurement. For example, sending 1,000 messages per second, with a message subscription volume of 2,000 and a message filtered volume of 5,000, the message sending/receiving TPS would be 1,000 + 2,000 + 5,000 = 8,000 times/second.
    3. Message size is measured in 4 KB, and TPS is calculated based on different multiples depending on message size:
    Message size
    Multiples
    N ≤ 4 KB
    1
    4KB < N ≤ 16KB
    2
    16 KB < N ≤ 100 KB
    8
    100 KB < N ≤ 1 MB
    32
    1 MB < N ≤ 5 MB
    128
    For example, if the message receiving volume is 5,000 messages per second, and the message sending volume is 5,000 messages per second, with an average message body size of 8 KB, then the message sending and receiving TPS is (8/4)x(5,000+5,000)=20,000 times/second.

    Elastic Storage Costs

    TDMQ for Pulsar pro cluster (elastic storage) employs linear pricing for storage. Storage Costs = Message Storage Size x Storage Unit Price x Duration .
    Note
    Pulsar by default stores messages in three replicas, so the billed storage size is approximately three times the total size of the monitored messages.
