Types ¶
type BackOff ¶
type BackOff interface {
// BackOff returns the amount of time to wait before the next retry given
// the number of consecutive failures.
BackOff(retries int) time.Duration
}
BackOff defines the methodology for backing off after a call failure.
type BackOffConfig ¶
type BackOffConfig struct {
// MaxDelay is the upper bound of BackOff delay.
MaxDelay time.Duration
// baseDelay is the amount of time to wait before retrying after the first
// failure.
BaseDelay time.Duration
// factor is applied to the BackOff after each retry.
Factor float64
// jitter provides a range to randomize BackOff delays.
Jitter float64
}
BackOffConfig defines the parameters for the default BackOff strategy.
