    The short answer · 14 words

    In short

    Exponential backoff typically increases the waiting times between repeat attempts by a fixed factor.

    Practical

    The pattern can reduce the load by repetitions of temporary errors; it needs upper limits and appropriate error handling.

    Hypothetical example: An integration waits after HTTP 429 increasingly longer and takes into account `Retry-After`.

    SMEs can make integrations more robust if retry limits, idem potency and dead letter pathways are defined.

    At a glance

    Core
    After temporary errors, the interval typically grows exponentially and is often complemented by random jitter to avoid simultaneous repetitions.

    Questions about this term

    Which mistakes repeat?

    Only if a new attempt is meaningful and safe.

    Why Jitter?

    It distributes repetitions in time and reduces synchronized retry waves.

    ELI5 – Explained simply

    After each failure, the system waits much longer before trying again.

    Why it matters in practice

    The pattern can reduce the load by repetitions of temporary errors; it needs upper limits and appropriate error handling.

    Example

    Hypothetical example: An integration waits after HTTP 429 increasingly longer and takes into account `Retry-After`.

    Pitfalls and limits

    • Repeat permanent errors endlessly; no jitter; duplicate non-idempotents; ignore server hints.

    Origin & history

    Cloud clients often use limited exponential backoff with jitter; HTTP 429 and a possible retry-after header have been standardized since RFC 6585 of 2012.

    Use in mid-sized companies

    • SMEs can make integrations more robust if retry limits, idem potency and dead letter pathways are defined.
