Can we configure retry attempts on AWS Go SDK service calls

Question

AWS by default provides retries support on its service calls, which is usually set to a max of 3 attempts.

Can we configure the retry object to set retry attempts to 5?

Answer 1

Yes, AWS provides support to configure their retry and timeouts features. Here are two ways to increase the max number of retries to 5 in AWS Golang SDK v2:

1. Configure the retry logic on the AWS Config object cfg and it can be used with various AWS service clients using NewFromConfig function

cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRetryer(func() aws.Retryer {
    return retry.AddWithMaxAttempts(retry.NewStandard(), 5)
}))

client := s3.NewFromConfig(cfg)

2. Configure the retry logic only for a specific AWS service client

customRetry := retry.NewStandard(func(o *retry.StandardOptions) {
        o.MaxAttempts = 5
    })

sqsClient := sqs.NewFromConfig(creds,
    func(o *sqs.Options) {
        o.Retryer = customRetry
    },
)
