Feature #19972
Updated by Peter Amstutz over 1 year ago
arvados.Client currently does not perform any retry behavior when a request fails with a 5xx error.
5xx errors should be retried with a random backoff time. Possible behavior:
1st attempt wait 0-1 seconds
2nd attempt, wait 1-2 seconds
3nd attempt, wait 2-3 seconds
4nd attempt, wait 3-5 seconds
5th attempt, wait 5-8 seconds
The idea being that if the API server is overloaded, the clients should all select different retry intervals so that they don't just flood the API server by all retrying at a fixed time.
