Section titled “miniproto.media.retry.backoff_delay”
backoff_delay(attempt: int, *, base: float = DEFAULT_BACKOFF_BASE, cap: float = DEFAULT_BACKOFF_CAP, jitter: float = DEFAULT_BACKOFF_JITTER) -> float

Calculate a jittered exponential delay for a transient non-flood retry.

Parameters:

  • attempt (int) – Zero-based failed attempt; 0 produces approximately base seconds.
  • base (float) – Initial delay in seconds; defaults to :data:DEFAULT_BACKOFF_BASE.
  • cap (float) – Maximum unjittered delay in seconds; defaults to :data:DEFAULT_BACKOFF_CAP.
  • jitter (float) – Symmetric random fraction applied to the capped delay; defaults to :data:DEFAULT_BACKOFF_JITTER.

Returns:

  • float – A non-negative sleep duration in seconds. Randomization prevents synchronized retries.
