batch-backoff

Provides exponential backoff for batch processes

Useful when you want exponential backoff when running async batch processes. eg. when you want the following to only result in a single backoff operation.

for i := 0; i < 20; i++ {
    doProcessCall()

    Backoff()
}

Install

go get github.com/johan-lejdung/batch-backoff

Usage

Import the package

import bboff github.com/johan-lejdung/batch-backoff

Create a new instance of the struct with:

backoff := bboff.NewExponentialBackoff(bboff.BackoffIntervals{
    StartInterval: 10 * time.Minute,
    Multiplier:    2,
    MaxInterval:   2 * time.Minute,
})

You use the library by first calling CanProceed().

You will get back (bool, BackoffBatch), where the bool indicates if you can proceed or not.

The batch is used when calling Backoff(batch BackoffBatch). If the call made after CanProceed() fails you just need to provice the BackoffBatch to the call of Backoff and the increments will handle it self.
