This document mainly describes the specifications of the TDMQ for Apache Pulsar Pro cluster (elastic storage), including TPS, bandwidth, and topic quantity limit. They are used for your selection.
Note:
1. Pro cluster storage uses a triple replica mechanism to ensure data high availability.
2. Pro clusters support online upgrade configuration. For specific operations, see the document Upgrading Cluster. Theoretically, the upgrade process should be seamless for the business. However, during server-side Rebalance Topic operations, clients may experience disconnections followed by reconnections.

Notes

Message receiving/sending TPS limit is calculated based on the sum of sent and received messages assuming standard message type and a message size of 4 KB. Calculations for advanced feature messages and large messages need to be multiplied by the corresponding rate. Peak bandwidth refers to the exact values for inbound and outbound bandwidth. For the specific calculation method, see Pro Cluster Billing.
Topic Number of Partitions refers to the sum of the number of partitions for all topics under a cluster, i.e., if a cluster has 2 topics with 3 partitions each and 1 topic with 2 partitions, then the Topic Number of Partitions is: 3 * 2 + 2 = 8.
