package backoff

import "google.golang.org/grpc/internal/backoff"

Package backoff implement the backoff strategy for gRPC.

This is kept in internal until the gRPC project decides whether or not to allow alternative backoff strategies.

Variables ¶

var DefaultExponential = Exponential{Config: grpcbackoff.DefaultConfig}

DefaultExponential is an exponential backoff implementation using the default values for all the configurable knobs defined in https://github.com/grpc/grpc/blob/master/doc/connection-backoff.md.

Types ¶

type Exponential ¶

type Exponential struct {
	// Config contains all options to configure the backoff algorithm.
	Config grpcbackoff.Config
}

Exponential implements exponential backoff algorithm as defined in https://github.com/grpc/grpc/blob/master/doc/connection-backoff.md.

func (Exponential) Backoff ¶

func (bc Exponential) Backoff(retries int) time.Duration

Backoff returns the amount of time to wait before the next retry given the number of retries.

type Strategy ¶

type Strategy interface {
	// Backoff returns the amount of time to wait before the next retry given
	// the number of consecutive failures.
	Backoff(retries int) time.Duration
}

Strategy defines the methodology for backing off after a grpc connection failure.
