Często zadawane pytania

When should I use exponential backoff?
For API retries (429/5xx), queues, and DB clients — to avoid hammering the service.
What does a longer backoff give?
Slower retries and less load; too long without a cap delays recovery.
What values are typical?
Base 0.5–2 s, multiplier 2, max a few–tens of seconds; jitter 10–50%.
What looks “bad”?
Fixed short retries without cap/jitter, or uncapped growth into minutes.
