Constants

const JitterFraction = 0.25

JitterFraction is the proportion of the base duration used for jitter. A value of 0.25 means the returned duration will be in the range [base * 0.75, base * 1.25].

Functions

func WithJitter

func WithJitter(d time.Duration) time.Duration

WithJitter adds +/-25% random jitter to a duration to prevent thundering herd effects. The result is always non-negative; if the computed value would go below zero (extremely short durations), zero is returned.
