💡 Idea

The retry based on Rican7/retry but fully reworked and focused on integration with the 🚧 breaker and the built-in context package.

ctx, cancel := context.WithTimeout(context.Background(), time.Minute)
defer cancel()

action := func(ctx context.Context) (err error) {
	req := req.Clone(ctx)
	resp, err = http.DefaultClient.Do(req)
	return err
}

how := []retry.How{
	strategy.Limit(5),
	strategy.BackoffWithJitter(
		backoff.Fibonacci(10*time.Millisecond),
		jitter.NormalDistribution(
			rand.New(rand.NewSource(time.Now().UnixNano())),
			0.25,
		),
	),
}

if err := retry.Do(ctx, action, how...); err != nil {
	log.Fatal(err)
}

A full description of the idea is available here.

🏆 Motivation

I developed distributed systems at Lazada, and later at Avito, which communicate with each other through a network, and I need a package to make these communications more reliable.

🧩 Integration

The library uses SemVer for versioning, and it is not BC-safe through major releases. You can use go modules to manage its version.
