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.

type Exponential ¶ Uses

type Exponential struct {
    // MaxDelay is the upper bound of backoff delay.
    MaxDelay time.Duration
}

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

func (Exponential) Backoff ¶ Uses

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 ¶ Uses

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.
