    This document describes the specifications of TDMQ for Apache Pulsar pro clusters (elastic storage), including TPS, bandwidth, and the maximum number of topics, for reference during product selection.
    Note:
    1. The storage system of pro clusters uses three replicas to ensure high data availability.
    2. Pro clusters support online specification upgrades. For specific operations, see Upgrading Cluster Specifications. The upgrade process is theoretically imperceptible to businesses. However, clients may experience disconnections and reconnections when the server rebalances topic traffic.
    3. TDMQ for Apache Pulsar pro clusters (elastic storage) have a maximum of 100 namespaces regardless of the broker version.

    Must-Knows

    Maximum TPS for Message Sending and Receiving is calculated based on the sum of sent and received general messages with a message size of 4 KB. For advanced feature messages or large messages, the value should be multiplied by the corresponding multiplier. Peak Bandwidth indicates the maximum inbound and outbound bandwidth values. For detailed calculation methods, see Billing Overview of Pro Clusters.
    Topic x Number of Partitions indicates the total number of partitions of all topics in a cluster. For example, if a cluster contains 2 topics with 3 partitions each and 1 topic with 2 partitions, Topic x Number of Partitions is 8 (3 x 2 + 2 = 8).
