var ExponentialCalculationsCount = int(math.Log(MaxExponentialBackoffDelay.Seconds()) / math.Log(ExponentialDelayFactor))
Count of exponential calculations before return max delay to prevent overflow with big numbers.
Functions ¶
func CalculateDelay ¶
CalculateDelay returns delay distributed from initialDelay to default maxDelay (32s)
Example:
Retry 0: 5s Retry 1: 6s Retry 2: 7.8s Retry 3: 9.8s Retry 4: 13s Retry 5: 21s Retry 6: 32s Retry 7: 32s
func CalculateDelayWithMax ¶
func CalculateDelayWithMax(initialDelay time.Duration, maxDelay time.Duration, retryCount int) time.Duration
CalculateDelayWithMax returns delay distributed from initialDelay to maxDelay based on retryCount number.
Delay for retry number 0 is an initialDelay.
Calculation of exponential delays starts from retry number 1.
After ExponentialCalculationsCount rounds of calculations, maxDelay is returned.
