ApsaraVideo Live limits the queries per second (QPS) of an API operation for each account. If the number of calls of an API operation in a second or minute exceeds the limit, throttling is triggered. This topic describes the QPS limits on calling different API operations in ApsaraVideo Live. To prevent service interruptions, we recommend that you take note of the limit when you call an API operation.
QPS limit on calling an API operation
The QPS limit on calling an API operation indicates the maximum number of times that an Alibaba Cloud account and the RAM users that belong to the account can call the API operation per second or per minute. For example, the QPS limit on calling the AddLiveDomain operation is 30 times per second per account. If you have an Alibaba Cloud account and five RAM users that belong to the account, the Alibaba Cloud account and five RAM users all together can call the AddLiveDomain operation no more than 30 times per second.
Not all API operations have a QPS limit. The following tables describe the QPS limits on calling different API operations in ApsaraVideo Live.
