Harness internally imposed a limit to allow a certain number of requests per minute as well as per second.
The limit we have imposed is if an account exceeds 350 QPM or 350/60 = 5.833 QPS then the requests will be throttled for all the external facings APIs.
There are 14 external facing API resources and this limit applies to all those APIs.
350 QPM and 5.833 QPS
The limit gets imposed based on QPM as well as QPS.
The Ratelimiter decides on what seconds out of the 60 for every minute which 50 seconds it will allow 6 QPS and rest 10 seconds allow only 5.
While running queries you might sometimes observe 429s that is because of the above limit.
429 - Server Errors : The rate limit is exceeded.
