By implementing retries with exponential backoff and jitter, the developer can ensure that the message processing is retried reliably without overwhelming the service after an outage. Exponential backoff increases the delay between retry attempts, reducing the load on the service when it recovers, and jitter adds randomness to these delays to prevent synchronized retries. A dedicated error queue is not a retry mechanism but rather a way to separate unprocessable messages. Unlimited immediate retries could easily overwhelm the service, and increasing the message visibility timeout alone does not provide a mechanism for retrying message processing.
