# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Build Status][travis image]][travis] [![Coverage Status][coveralls image]][coveralls]
|
||
|
|
|
||
|
|
This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].

|
[Exponential backoff][exponential backoff wiki]
|
||
|
|
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
|
||
|
|
in order to gradually find an acceptable rate.
|
||
|
|
The retries exponentially increase and stop increasing when a certain threshold is met.

|
## Usage
|
||
|
|
|
||
|
|
Import path is `github.com/cenkalti/backoff/v4`. Please note the version part at the end.
|
||
|
|
|
||
|
|
godoc.org does not support modules yet,
|
||
|
|
so you can use https://godoc.org/gopkg.in/cenkalti/backoff.v4 to view the documentation.

|
* I would like to keep this library as small as possible.
|
||
|
|
* Please don't send a PR without opening an issue and discussing it first.
|
||
|
|
* If proposed change is not a common use case, I will probably not accept it.
