Hi Charles, the particular limit you're hitting is an internal limit that's currently not listed in the public documentation. Could you open a case using this link or file a limit increase on DeleteFaces API and we can then engage on the case to help.
We understand that the limit is not a good customer experience and there're a few options that's available to help.
The 2 pages I'm looking at are https://docs.aws.amazon.com/rekognition/latest/dg/limits.html and https://docs.aws.amazon.com/general/latest/gr/rekognition.html.
I don't see anything else. Could you check https://us-west-2.console.aws.amazon.com/servicequotas/home/services/rekognition/quotas/L-220834FB (Use the region you're working in) and see the history?
Some options include configuring exponential backoff and jitter, configuring retries, queuing as well. Alternatively, you could increase the service quota too.
