A single user can perform a maximum of 4 queries per second (QPS). Throttling is triggered when the number of calls per second exceeds the QPS limit. The throttling may affect your business. Thus, we recommend that you observe the QPS limit on this operation. For more information about what a single user means and the QPS details, see QPS limit on an API operation in ApsaraVideo Live.
