QPS limits-ApsaraMQ for MQTT(MQTT)-阿里云帮助中心

ApsaraMQ for MQTT limits the frequency of API calls. These limits are measured in queries per second (QPS). If you exceed a QPS limit, your requests are throttled. Throttling can impact your business. To avoid service disruptions, call APIs within the specified limits.

ApsaraMQ for MQTT server-side API calls have QPS limits. These limits fall into two categories:

Per-user API QPS limits: If you exceed this limit, your requests are throttled. Service guarantees under the Service-Level Agreement (SLA) apply only to traffic within the specified limits. For the specific QPS limits for each API, see Table 1.
Per-source IP address QPS limits: If you exceed this limit, the source IP address is blocked.
Note
The global QPS limit for a single source IP address is 300 for all APIs.
