QPS limits - ApsaraVideo Media Processing - Alibaba Cloud Documentation Center

ApsaraVideo Media Processing (MPS) limits the queries per second (QPS) of API calls for each account. API calls are throttled if the QPS limit per account is exceeded. This topic describes the QPS limit per account on each API operation in MPS. To prevent your service from being interrupted by throttling, we recommend that you keep your number of API calls per second under the QPS limit.

QPS limit per account on an API operation

The QPS limit per account on an API operation specifies the maximum number of times that an Alibaba Cloud account and the Resource Access Management (RAM) users that belong to this account can call the API operation per second. For example, the QPS limit per account on the ActivateMediaWorkflow operation is 100 times per second. If you have an Alibaba Cloud account within which five RAM users are created and use the Alibaba Cloud account and the five RAM users to call the ActivateMediaWorkflow operation at the same time, the total number of calls per second cannot exceed 100.

Important

Not all API operations have QPS limits. The following tables describe the QPS limits on calling different API operations.
Take note of the units in the following tables. The default unit is times per second. Other units are provided if used, such as times per minute.
