What is Retry Budget?
A bound on retry traffic, usually expressed relative to original requests or over a time window, that prevents retries from consuming unbounded capacity.
Why does Retry Budget matter?
When a dependency slows or fails, unrestricted retries multiply load exactly when the system has the least spare capacity.
Retry Budget in practice
Count retries separately from first attempts, cap them by service and tenant, honor deadlines, use jittered backoff, and stop retrying non-transient or non-idempotent failures.
What is the common confusion about Retry Budget?
A retry budget limits extra attempts. An error budget measures user-visible unreliability allowed by an SLO.
