Does AWS SDK handles session expiry automatically?

Question

I am writing a client to get the continuous messages from RabbitMQ and pushing to AWS SQS service. But I'm not sure about the session expiry, If the session expires do we need to recreate the session or AWS SDK handles it automatically?

log.Printf("PPU Message Broker: Pushing messages to SQS")
    sess, err := session.NewSession(&aws.Config{
        Region:      aws.String("us-east-1"),
        //Credentials: credentials.NewSharedCredentials("", "sqs_user"),
    })
    _, err = sess.Config.Credentials.Get()
    if err != nil {
        log.Fatalf("PPU Message Broker: Credentails Failed")
    }
    svc := sqs.New(sess)    
    result, err := svc.SendMessage(&sqs.SendMessageInput{
        MessageBody:    aws.String(string(data)),
        MessageGroupId: aws.String("TestGroup"),
        QueueUrl:       &qURL,
    })

There is a default configuration for session expiration, but you can specify yours:

In addition to NewSession, you can create sessions using NewSessionWithOptions. This function allows you to control and override how the session will be created through code, instead of being driven by environment variables only.

Use NewSessionWithOptions when you want to provide the config profile

Inside of the Options object, there is an attribute for changing the default expiration time, by default is 15 minutes:

// When the SDK's shared config is configured to assume a role this option // may be provided to set the expiry duration of the STS credentials. // Defaults to 15 minutes if not set as documented in the // stscreds.AssumeRoleProvider. AssumeRoleDuration time.Duration
