The maximum number of concurrent requests that an individual worker can service. Launch automatically scales the number of workers for the endpoint so that each worker is processing per_worker requests, subject to the limits defined by min_workers and max_workers.

• If the average number of concurrent requests per worker is lower than per_worker, then the number of workers will be reduced. - Otherwise, if the average number of concurrent requests per worker is higher than per_worker, then the number of workers will be increased to meet the elevated traffic.

Here is our recommendation for computing per_worker:

1. Compute min_workers and max_workers per your minimum and maximum throughput requirements. 2. Determine a value for the maximum number of concurrent requests in the workload. Divide this number by max_workers. Doing this ensures that the number of workers will "climb" to max_workers.
