Request Throttling

Updated on 2024-10-29 GMT+08:00

What Is Request Throttling?

Request throttling is a method used by Huawei Cloud to control the frequency of calling open APIs. A quota refers to the maximum number of calls made to a single API within a specified time window.

Request Throttling for Partner Operations Capability APIs

NOTE:

Traffic quota: 10/1(s); API request throttling dimensions: source IP address, API, and ParentUid, indicating that a single user or source IP address can send up to 10 requests to the API every second.

Troubleshooting for Request Throttling Failure

The following is an example of error returned by an API:

{"status_code":429,"request_id":"7e6c1***********c610","error_code":"APIGW.0308","error_message":"The throttling threshold has been reached: policy user over ratelimit,limit:10,time:1 second","encoded_authorization_message":""}

Troubleshooting

Huawei Cloud provides default traffic quotas for partner operations capability APIs. Users can increase the quota based on their service requirements. They can monitor status code 429 and construct a retry mechanism. The retry mechanism should follow an exponential backoff plan to reduce the number of requests if necessary. They can also establish some randomness in the backoff timesheets to avoid severe herd mentality.

Adjusting Quotas

If the traffic quota cannot meet your service requirements and concurrency scenarios, submit a Huawei Cloud service ticket with the service scenario description attached. After receiving the service ticket, the Huawei Cloud after-sales service team will adjust the quota based on your requirements.
