Sometimes an asynchronous event might not be handled successfully. In such events, we would like to retry for a certain number of times before considering the message a dead letter.

A notification is retried with exponential back off [1].

Notes

  1. Requires RabbitMQ queues since RabbitMQ has native support for delaying message delivery and automatic dead letters.
