Query rate per second QPS(Query Per Second) indicates the peak number of requests sent to the server per second, which is the maximum number of concurrent requests that each API can allow per second. If the limit is exceeded, throttling may affect your business. Therefore, you must use it properly. After reading this topic, you can understand the API QPS limits for Real-Time Communication data service single users.

Maximum QPS per user

The API QPS limit for a single user refers to the maximum frequency that the account and its RAM users can call an API per second or every minute based on an Alibaba Cloud account. For example, if an Alibaba Cloud account and its corresponding five RAM users call the API DescribeCallList at the same time (the QPS of a single-user API is limited to 10 times per second), the total frequency of the Alibaba Cloud account and its corresponding five RAM users calling the API cannot exceed 10 times per second.

The Real-Time Communication Data Service Single User API QPS limits are as follows:
