Retries
3 engineering logs on Retries. Newest first.
- Retry storms: how the resilience layer became the outage
Why retries at every layer multiply rather than add, why a dependency recovering into full retry load never actually recovers, and why a retry budget is the only control that bounds the total.
- Idempotency keys: the API contract that makes retries safe
Why a timeout tells the client nothing about whether the write happened, why storing the key after the work is a race rather than a fix, and why the stored response has to be replayed rather than recomputed.
- Jitter is the cheapest reliability fix you are not using
Why independent clients converge on the same instant without any coordination, how retries, cron schedules, health checks and reconnects all self-synchronise, and why adding randomness is a one line fix for a class of outage.
