Mechanisms¶
- Safe Missing-Referent Fallback
- Over-eager retries against a struggling dependency turn a small outage into a self-inflicted retry storm.
This sourceExplains that aggressive retries add load to an already overloaded dependency and can amplify the failure.

- Safe Retry Protocol
- The discipline is exponential backoff with jitter, a hard retry budget, and a circuit breaker
This sourceAmazon Builders' Library. (2019). Recommends exponentially increasing retry delays with randomized jitter and limiting retries with a retry budget or maximum attempt count.
- The discipline is exponential backoff with jitter, a hard retry budget, and a circuit breaker
- Timeout and Retry Recovery
- Its signature failure is livelock: participants that time out and retry in lockstep keep colliding, so the system is busy but frozen — motion without progress.
This sourceAmazon Builders’ Library (nd). Shows that clients retrying in lockstep can repeatedly collide and amplify overload, which jitter is designed to break.
- Its signature failure is livelock: participants that time out and retry in lockstep keep colliding, so the system is busy but frozen — motion without progress.
Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
