A package for Optimistic Concurrency Control

This project is an improvement of the backoff package implemented by cenkalti/backoff. This package provides support for various other backoff algorithms and exposes them in a service-like fashion for use.

Backoff Algorithms such as Exponential Backoff are all part of a branch of computer science known as “Optimistic Concurrency Control”. The focus of these algorithms is to use feedback cycles and process staggering to determine an acceptable time at which a process can successfully complete its intended goal.

Supported Algorithms:

• Exponential Backoff
• Fibonacci (TBD)
• Equal Jitter (TBD)
• Full Jitter (TBD)
• Decorr (TBD)
• Custom Backoff (TBD)

• See the AWS Blog on Exponential Backoff and Jitter for more example information on the abovealgorithms

To install backoff, use go get:

go get github.com/defaltd/backoff

Import the backoff package into your code using this template:

package main

import (
    "fmt"
    "backoff"
)

func SayHello() {
    service := backoff.New(&backoff.Policy{
        Algorithm: backoff.AlgorithmExponential,
    })

    service.ExecuteAction(func() error { return client.MakeAPICall("Hello World"); })
}
