      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

      Currently, no throttling measures are taken by the system if your actual usage exceeds the upper limit of the purchased cluster specification. However, we recommend that you subscribe to the alarms for core cluster metrics, keep an eye on the processing performance in case of metric changes, and upgrade the cluster specification promptly to guarantee stable business operations. We may provide elasticity in this regard in the future to ease your worries.

      Cluster TPS specification

      1. Messaging TPS refers to the maximum sum of messages sent and subscribed per second.
      2. The message size is measured in 4 KB. For example, if the numbers of messages sent and received per second are both 5,000, and the average message body size is 8 KB, then the messaging TPS is (8 / 4) * (5,000 + 5,000) = 20,000 messages/sec.
      3. For advanced messages, that is, sequential, scheduled/delayed, and transactional messages, the number of calls for message sending needs to be five times that of general messages. For example, if 1,000 delayed messages are sent per second, the TPS for message sending is 1,000 * 5 = 5,000 messages/sec.
